Family Property, Spousal Support, and Child Support in Canada: Financial Consequences of Relationship Breakdown

Family Property, Spousal Support, and Child Support in Canada: Financial Consequences of Relationship Breakdown

1. Introduction

The breakdown of a marriage or common-law relationship can produce financial consequences that extend far beyond the immediate question of who will live in the family home. Separation may require the division of property accumulated during the relationship, the valuation of businesses and pensions, the allocation of debts, the payment of spousal support, and the establishment of financial arrangements for children. These questions are closely connected, but Canadian law treats them as distinct legal issues governed by different statutes, principles, and jurisdictional rules.

Canada does not have one national system for dividing family property or determining every form of financial support following separation. Family law is constitutionally divided between federal and provincial and territorial authority. The federal government has jurisdiction over divorce, while provinces and territories regulate property rights, civil obligations, and much of the law governing family relationships outside divorce proceedings. The result is a legal framework in which the applicable rules may depend on whether the parties were married, whether they are seeking a divorce, where they lived, where their property is situated, and whether children are involved.

Three major financial questions must therefore be distinguished:

1. Family property division: determining which assets and liabilities are included in the financial accounting between former partners and how their value is to be allocated.
2. Spousal support: determining whether one former spouse or partner must provide financial support to the other, and, if so, in what amount and for how long.
3. Child support: determining the financial contribution each parent must make toward the needs of their children after separation.

These obligations are not interchangeable. A spouse may have a right to a share of family property without being entitled to spousal support. A person who receives spousal support may also be entitled to child support on behalf of a child. Conversely, a parent may have to pay child support even where the other parent has no entitlement to spousal support.

The central principle is that separation does not extinguish financial responsibilities created during a relationship or by parenthood. Canadian law attempts to address the economic consequences of relationship breakdown, recognise the contributions made by both partners, protect children from the financial effects of parental separation, and provide a framework for resolving disputes fairly.

This article examines the principal legal rules governing family property, spousal support, and child support across Canada, with particular attention to the differences between common-law provinces and Quebec’s civil-law system.

2. Constitutional and Legislative Foundations

The financial consequences of separation are governed by a combination of federal and provincial or territorial legislation.

2.1 Federal authority over divorce

The federal government has constitutional authority over marriage and divorce under section 91(26) of the Constitution Act, 1867. The principal federal statute is the Divorce Act, which regulates divorce and certain related matters, including:

• Spousal support orders in divorce proceedings.
• Child support orders in divorce proceedings.
• The financial obligations of spouses arising from divorce.
• The relationship between child support and spousal support.
• The recognition and enforcement of certain support arrangements.

The Divorce Act does not establish a comprehensive national system for dividing matrimonial property. Property division is principally governed by provincial and territorial law. The federal Department of Justice expressly recognises that the rules governing property division vary across Canada. Ministère de la Justice+1

2.2 Provincial and territorial authority

Provinces and territories regulate property and civil rights, the administration of justice, and many aspects of family relationships. Their legislation commonly addresses:

• Division of property following marriage breakdown.
• Rights relating to the matrimonial or family home.
• Division or valuation of pensions.
• Property claims between unmarried partners.
• Spousal support outside divorce proceedings.
• Child support where the parents are not divorcing.
• Domestic contracts and separation agreements.
• Procedures for obtaining and enforcing family-law orders.

The applicable legislation differs considerably. Ontario, British Columbia, Alberta, Manitoba, Saskatchewan, the Atlantic provinces, and the territories each have their own statutory framework.

A person seeking a divorce may therefore rely on federal law for support claims while relying on provincial or territorial law for property division. The two processes may take place within the same family-law proceeding, but they remain legally distinct.

2.3 The significance of Quebec’s civil-law system

Quebec regulates private-law family relationships primarily through the Civil Code of Québec. Its legal framework includes:

• Family patrimony.
• Matrimonial regimes.
• Civil unions.
• Parental authority and obligations.
• Support between spouses and relatives.
• Obligations arising from parenthood.
• The division of certain family assets and pension rights.

Quebec’s system differs structurally from the common-law property regimes used elsewhere in Canada. It is therefore misleading to assume that concepts such as equalization of net family property, used in Ontario, operate in the same way in Quebec.

The Civil Code of Québec is the principal legislative source for these rules. Les Publications du Québec

3. Family Property Division: General Principles

Family property division concerns the financial adjustment between partners when their relationship ends. The purpose is not necessarily to divide every physical object equally or to give each person half of every asset. Instead, legislation establishes a method for identifying relevant property, determining its value, applying exclusions and deductions, and calculating any payment required to achieve the legally prescribed result.

3.1 Legal ownership and family-property rights

An important distinction exists between ownership of an asset and entitlement to a financial adjustment upon separation.

A house may be registered in the name of one spouse alone. A bank account may belong legally to only one partner. A business may have been incorporated and owned by one spouse. Nevertheless, the applicable family-property legislation may include the value of these assets in a calculation between the parties.

This does not necessarily transfer legal title to the other spouse. In many jurisdictions, the law creates a right to an equalization payment or another form of financial adjustment rather than an automatic transfer of ownership.

The legal analysis must therefore distinguish:

• Who legally owns the asset.
• Whether the asset is included in the family-property regime.
• Whether an exclusion or exemption applies.
• What valuation date the law uses.
• Whether a debt associated with the asset is deductible.
• Whether the result is an entitlement to property itself or to a monetary payment.

3.2 Marriage and common-law relationships

One of the most important differences in Canadian family law concerns the legal consequences of marriage compared with cohabitation outside marriage.

Marriage generally activates a statutory family-property regime. The precise mechanism differs by jurisdiction, but married spouses commonly acquire rights to a financial adjustment when the relationship ends.

Common-law partners do not necessarily receive the same rights. In some provinces, legislation provides a property-sharing regime for qualifying unmarried partners. In others, the parties may have to rely on ordinary property law, unjust enrichment, constructive trust principles, or a domestic agreement.

The length of cohabitation may be relevant, but it does not automatically create identical property rights throughout Canada.

The distinction is particularly important for people who have lived together for many years, purchased property jointly, contributed to a partner’s business, or organised their relationship around one partner earning income while the other provided unpaid domestic and caregiving work.

A person should not assume that a long relationship automatically produces the same property rights as marriage. Equally, a person should not assume that an unmarried partner has no possible claim. The applicable provincial or territorial law must be examined.

3.3 The family home

The family home frequently represents the most valuable asset in a relationship. It may also have special statutory protection.

Depending on the jurisdiction, the family home may be subject to rules concerning:

• Consent before sale or mortgage.
• Possession or occupation after separation.
• Restrictions on unilateral transfer.
• Inclusion in property division.
• Special treatment of inherited or premarital property.
• Valuation and sale arrangements.

The fact that one spouse purchased the home before marriage does not necessarily mean that its full value is excluded from family-property calculations. Some jurisdictions treat the matrimonial home differently from other premarital assets.

For example, Ontario’s Family Law Act contains a distinctive rule concerning the matrimonial home. In calculating net family property, a spouse generally cannot deduct the value of a matrimonial home owned on the date of marriage if it remains the matrimonial home at the relevant valuation date. The rule can therefore produce a different result from the treatment of other assets acquired before marriage. ontario.ca

The family home may also create practical difficulties. One spouse may wish to remain in the property with the children, while the other may seek its sale or a payment reflecting their interest. A court may have to consider possession, financial capacity, mortgage obligations, children’s circumstances, and the broader property division.

Property division and parenting arrangements remain legally separate questions. The parent who has more parenting time does not automatically become the sole owner of the family home.

3.4 Debts and liabilities

Family-property calculations may include debts as well as assets. These can include:

• Mortgages.
• Personal loans.
• Credit-card balances.
• Lines of credit.
• Business liabilities.
• Tax debts.
• Student loans.
• Other legally recognised financial obligations.

The treatment of debt depends on the applicable statute and the circumstances in which the liability arose. Some debts may be excluded or treated differently, particularly where they were incurred for an improper purpose or are not legally attributable to the relevant property calculation.

It is also essential to distinguish the internal financial allocation between spouses from the rights of creditors. A separation agreement may state that one spouse is responsible for a mortgage or loan, but this does not necessarily release the other spouse from liability to the lender. Unless the creditor agrees to a change or the loan is refinanced, a person whose name remains on the loan may continue to be legally responsible.

This is a frequent source of financial risk after separation.

4. Property Division in Common-Law Provinces and Territories

Although the legislation varies, many common-law jurisdictions use a system designed to recognise the economic partnership created by marriage.

The mechanisms are not identical. Some jurisdictions calculate the value of property accumulated during marriage; others distinguish between family assets, excluded property, and property acquired before or during the relationship.

4.1 Ontario: Equalization of net family property

Ontario provides one of the clearest examples of a statutory equalization model.

Under the Family Law Act, each spouse calculates their net family property. Broadly, this involves determining the value of property owned on the valuation date, deducting qualifying debts and liabilities, and applying statutory deductions for certain property owned at marriage or received through specified sources.

The valuation date is generally the earliest of the date the spouses separate with no reasonable prospect of resuming cohabitation, the date a divorce proceeding begins, the date the marriage is declared a nullity, or the date of death, as applicable under the statute.

The spouse with the higher net family property will generally owe the other spouse an equalization payment equal to one-half of the difference between the two net family property amounts.

The calculation is not the same as dividing every asset in half. One spouse may retain the house, while the other retains investments or a business interest, provided the overall financial adjustment satisfies the statutory framework.

Certain assets may be excluded, subject to statutory conditions. These can include inheritances and gifts received from third parties during marriage, provided the relevant requirements are met. However, the matrimonial home is subject to special rules, and an inheritance used to acquire or improve the matrimonial home may lose the protection that might otherwise have applied.

Ontario’s regime also recognises the possibility of an unequal division in exceptional circumstances where equalization would be unconscionable under the statutory test.

4.2 British Columbia: Family property and excluded property

British Columbia’s Family Law Act provides a system based on family property and family debt.

Family property generally includes property acquired by either or both spouses during the relationship, as well as certain interests acquired before separation. The definition can include real estate, bank accounts, investments, businesses, pensions, and other valuable interests.

The legislation also recognises excluded property, which may include:

• Property owned by a spouse before the relationship began.
• Gifts received from third parties.
• Inheritances.
• Certain trust interests.
• Certain damages or compensation awards.

However, the increase in value of excluded property during the relationship is generally treated as family property. This distinction can be significant where one spouse owned a property or business before the relationship but its value increased substantially during the relationship.

The default position is equal division of family property and family debt, subject to statutory exceptions and judicial discretion. A court may order unequal division where equal division would be significantly unfair, applying the statutory factors.

The British Columbia approach therefore differs from Ontario’s net-family-property equalization calculation, even though both systems seek to recognise the economic partnership of spouses.

4.3 Alberta and other provinces

Alberta’s Family Property Act provides for the distribution of property following the breakdown of a marriage or qualifying adult interdependent relationship. It gives courts discretion to distribute property in a manner considered just and equitable under the statutory framework.

The legislation recognises different categories of property and permits consideration of factors such as the parties’ contributions, the duration of the relationship, the circumstances in which property was acquired, and the financial consequences of the relationship.

Other provinces and territories have their own statutory systems. Saskatchewan, Manitoba, Nova Scotia, New Brunswick, Prince Edward Island, Newfoundland and Labrador, Yukon, the Northwest Territories, and Nunavut each have legislation that must be consulted independently.

The terminology may also differ. A statute may refer to family property, matrimonial property, marital property, or an equivalent concept. These expressions should not be treated as interchangeable without examining the relevant legal definitions.

5. Family Property in Quebec: Family Patrimony and Matrimonial Regimes

Quebec’s system is particularly important because it combines a mandatory family-patrimony framework with matrimonial regimes governing other property.

5.1 Family patrimony

Under the Civil Code of Québec, married spouses and civil-union partners are generally subject to the rules of family patrimony, irrespective of their matrimonial regime.

The family patrimony includes specified categories of property used by the family, such as:

• Family residences.
• Rights conferring use of family residences.
• Furniture used to furnish or decorate family residences.
• Motor vehicles used for family transportation.
• Certain pension rights accumulated during the marriage or civil union.

The basic principle is that the net value of the family patrimony is divided equally, subject to statutory rules, deductions, and possible judicial adjustments.

Importantly, the law divides the value of the family patrimony rather than necessarily dividing each physical asset. One spouse may retain the residence while the other receives an appropriate financial adjustment.

The family-patrimony regime is designed to protect economic contributions that may not appear in formal ownership documents. A spouse who devoted substantial time to childcare and domestic responsibilities may have contributed to the family’s economic life even if the other spouse earned most of the income and held title to most assets.

Official Quebec guidance explains that the family-patrimony rules apply automatically to married and civil-union couples, subject to exceptions, and that the value of qualifying property is generally divided equally. Gouvernement du Québec+1

5.2 Matrimonial regimes

In addition to family patrimony, Quebec spouses are governed by a matrimonial regime.

Where the spouses have not entered into a marriage contract selecting another regime, the default regime is generally the partnership of acquests.

Under this regime, property is classified broadly as either private property or acquests. Private property generally includes certain assets owned before marriage and specified categories of property acquired during marriage, while acquests generally include property acquired through the spouses’ work or income during the marriage.

On dissolution of the matrimonial regime, the net value of acquests is divided according to the applicable rules.

Spouses may also choose separation as to property through a marriage contract made before a notary. However, choosing separation as to property does not remove the mandatory family-patrimony rules.

The distinction matters because the family patrimony and matrimonial regime operate as separate legal mechanisms. The first identifies specified family assets subject to statutory sharing; the second governs the broader proprietary relationship between spouses.

5.3 De facto spouses

Quebec historically treated de facto spouses differently from married and civil-union partners in property division and spousal support. Cohabitation alone did not generally confer the same rights to family patrimony or spousal support.

However, Quebec introduced a parental union regime that came into force on 30 June 2025. It applies to qualifying de facto couples who become parents of a common child through birth or adoption on or after that date, subject to the statutory conditions. The regime creates a parental union patrimony and associated legal consequences. It does not make all unmarried cohabitants equivalent to married spouses.

Accordingly, the date on which a child was born or adopted, the parties’ relationship status, and any applicable agreement or opt-out mechanism may be legally significant. This is an important recent development for couples living together in Quebec.

6. Valuation, Excluded Property, Pensions, and Businesses

A property division is only as reliable as the identification and valuation of the assets and liabilities included in it. Disputes often arise not because the parties disagree about the general legal principle, but because they disagree about what an asset is worth, when it should be valued, or whether it qualifies for exclusion.

6.1 Valuation dates

Family-property statutes establish the date at which assets and liabilities are valued. This date may be the date of separation, the date proceedings begin, or another date prescribed by legislation.

The valuation date matters because financial circumstances can change considerably after a relationship ends. A business may increase or decrease in value. Investments may rise or fall. A spouse may incur new liabilities. Property may be sold, transferred, or damaged.

A court may also have to distinguish between changes in value attributable to ordinary market conditions and changes resulting from one spouse’s conduct.

The applicable statute may permit adjustments where a party has deliberately depleted assets, transferred property to defeat the other’s claim, or incurred liabilities in circumstances that justify a different treatment.

6.2 Inheritances and gifts

Many provincial statutes exclude certain gifts and inheritances received from third parties during a relationship. The rationale is that these assets were not necessarily created through the joint economic partnership of the spouses.

However, exclusion is not automatic in every circumstance. The recipient may have to establish the source of the asset and demonstrate that it remained identifiable or was dealt with in a way that preserved its statutory status.

For example, an inheritance deposited into a separate account may be easier to trace than an inheritance mixed with ordinary household funds and used over several years. The purchase of a family residence with inherited money may also have special consequences, as Ontario’s matrimonial-home rules illustrate.

The distinction between the original asset and any increase in value is equally important. Some statutes treat the original inheritance as excluded but include its appreciation in family property. Others may provide a different result depending on the circumstances.

6.3 Pensions and retirement benefits

Pension rights can represent a substantial part of the economic value accumulated during a relationship. They may include:

• Defined-benefit occupational pensions.
• Defined-contribution pension plans.
• Public-sector retirement benefits.
• Registered retirement savings plans.
• Locked-in retirement accounts.
• Government pension credits.
• Certain deferred compensation arrangements.

The fact that a pension has not yet been paid does not necessarily remove it from the property calculation. Its value may have to be determined actuarially or under statutory valuation procedures.

Pension division can be complex because the parties may have to distinguish between benefits accrued before, during, and after the relationship. The governing pension legislation and family-property statute may also impose particular procedures for dividing benefits or transferring amounts between accounts.

In Quebec, pension rights accumulated during marriage or civil union are among the categories included in family patrimony, subject to the relevant statutory rules.

6.4 Businesses and professional practices

A privately held company, partnership interest, professional practice, or family business may be one of the most difficult assets to value.

The valuation may require consideration of:

• Tangible assets and liabilities.
• Goodwill.
• Earnings and cash flow.
• Market conditions.
• Shareholder agreements.
• Minority interests.
• Restrictions on transferring shares.
• Tax consequences of a proposed sale or transfer.
• Whether the business depends heavily on the personal services of one spouse.

The spouse who operates the business may argue that its value is inseparable from their future labour. The other may argue that the business was built during the relationship through joint financial and non-financial contributions.

A professional valuation may be necessary. Courts may also have to consider whether a proposed valuation assumes a hypothetical sale, continued operation, or another appropriate method.

The inclusion of a business in a family-property calculation does not necessarily mean that the non-operating spouse becomes a shareholder or acquires management rights. The usual objective is to determine its value and reflect that value in the financial adjustment.

6.5 Financial disclosure

Full and accurate disclosure is fundamental to a fair property division. Relevant information may include:

• Bank and investment statements.
• Tax returns and notices of assessment.
• Pension statements and actuarial valuations.
• Mortgage and loan records.
• Corporate financial statements.
• Partnership agreements.
• Property appraisals.
• Trust documents where legally relevant.
• Records of significant transfers and gifts.

A spouse who conceals assets, undervalues property, or provides incomplete financial information may face adverse consequences. Courts can make disclosure orders, draw appropriate inferences, impose costs consequences, or grant other remedies available under the relevant law.

7. Domestic Contracts and Separation Agreements

Canadian family law permits spouses and, in many jurisdictions, qualifying unmarried partners to regulate aspects of their financial relationship through domestic contracts.

The terminology and legal requirements differ by province. Common forms include:

• Marriage contracts or prenuptial agreements.
• Cohabitation agreements.
• Postnuptial agreements.
• Separation agreements.

These instruments may address property division, spousal support, responsibility for debts, the use or sale of a family residence, and other financial arrangements.

7.1 Marriage and cohabitation agreements

A marriage contract or cohabitation agreement may establish how property will be treated if the relationship ends. It may also clarify the parties’ respective financial responsibilities during the relationship.

Such agreements can be particularly useful where one or both partners own a business, have substantial premarital assets, expect an inheritance, have children from previous relationships, or wish to maintain separate financial arrangements.

However, an agreement cannot necessarily override every statutory protection. Certain rights relating to the family home, child support, or other matters may be subject to mandatory legal rules.

7.2 Separation agreements

A separation agreement may resolve financial matters without requiring the parties to litigate every issue.

A comprehensive agreement can address:

• The division of real estate and personal property.
• The payment of equalization or other property adjustments.
• The treatment of debts.
• Pension division.
• Spousal support.
• Child support.
• Responsibility for extraordinary child-related expenses.
• Life insurance or security for support obligations.
• The timing and method of payments.
• Procedures for resolving future disagreements.

A separation agreement should distinguish clearly between property payments, spousal support, and child support. They have different legal purposes and may receive different tax treatment.

7.3 Validity and enforceability

A domestic contract may be challenged where there has been a failure to disclose significant assets or liabilities, where a party did not understand the nature or consequences of the agreement, or where the agreement was affected by coercion, undue influence, fraud, or other legally recognised grounds.

Independent legal advice is particularly important where the parties have unequal bargaining power or the agreement contains substantial financial waivers.

Courts do not necessarily set aside an agreement merely because one party later considers it unfair. The relevant statutory test and the circumstances surrounding its negotiation and execution must be examined.

7.4 Child support cannot simply be contracted away

Parents may agree on child-support arrangements, but they cannot conclusively determine that a child has no right to financial support.

Child support is treated as an obligation owed for the benefit of the child, not merely as a private financial entitlement belonging to the receiving parent. A court may refuse to enforce an agreement that fails to provide adequately for the child’s needs or is inconsistent with the applicable legal framework.

The same principle is relevant when parents agree to an amount below the applicable guideline figure. The court may examine whether the proposed arrangement is justified and consistent with the child’s interests.

8. Spousal Support: Purpose and Legal Foundations

Spousal support, sometimes called maintenance or alimony, is financial assistance that one spouse or qualifying partner may be required to provide to the other following separation or divorce.

It is not an automatic consequence of marriage breakdown. A difference in income alone does not establish entitlement. The court must examine the legal basis for the claim, the parties’ financial circumstances, the history of the relationship, and the economic consequences of separation.

8.1 Federal law and provincial law

The Divorce Act governs spousal support claims between married spouses who are divorcing. It applies throughout Canada.

Provincial and territorial legislation governs spousal support for unmarried partners and for married couples who separate but do not obtain a divorce. The eligibility requirements and relevant factors differ between jurisdictions.

In some provinces, common-law partners may qualify for spousal support after living together for a prescribed period or having a child together. In others, eligibility depends on a statutory definition of spouse or adult interdependent partner.

Quebec has historically taken a different approach: de facto spouses do not generally acquire the same statutory right to spousal support merely by living together. The parental union regime introduced in 2025 creates a new framework for qualifying parents, but it should not be confused with the legal status of marriage or civil union. Ministère de la Justice+2

8.2 Objectives of spousal support under the Divorce Act

Section 15.2 of the Divorce Act identifies the purposes and objectives of spousal support. These include:

1. Recognising economic advantages or disadvantages arising from the marriage or its breakdown.
2. Apportioning financial consequences arising from childcare responsibilities, beyond the separate obligation to support the child.
3. Relieving economic hardship arising from the breakdown of the marriage.
4. Promoting the economic self-sufficiency of each spouse within a reasonable period, so far as practicable.

These objectives reflect the reality that partners may have organised their economic lives around shared responsibilities. One spouse may have reduced working hours, abandoned a career opportunity, relocated, or undertaken most childcare duties to enable the other to pursue employment or professional advancement.

The resulting income disparity may continue long after the relationship ends.

Spousal support can therefore have both compensatory and non-compensatory purposes. It may recognise a disadvantage caused by the relationship, or respond to financial need arising from the breakdown itself.

8.3 Factors considered by courts

Under the Divorce Act, courts consider the condition, means, needs, and other circumstances of each spouse. Relevant considerations include:

• The length of time the spouses lived together.
• The functions performed by each spouse during the relationship.
• The economic consequences of those roles.
• The financial resources and obligations of each party.
• The care of children.
• Existing support orders or agreements.
• The parties’ ability to become self-sufficient within a reasonable period.

The law does not require a court to award support simply because one spouse earns more. A spouse with a lower income may have sufficient assets or independent resources, or the income difference may not be connected to the relationship or its breakdown.

Conversely, a spouse who has little current income may have a strong claim where the relationship created lasting economic disadvantages.

8.4 Marital misconduct

Canada’s divorce system is based on no-fault principles. The reasons why the marriage ended do not ordinarily determine entitlement to spousal support.

Adultery, abandonment, or other misconduct is not a general basis for increasing or reducing support. The legal focus is on economic consequences, needs, resources, and the statutory objectives rather than punishment for personal behaviour.

9. Compensatory and Non-Compensatory Support

Canadian courts recognise different legal foundations for spousal support. These are not rigid categories that always operate independently; a claim may involve more than one rationale.

9.1 Compensatory support

Compensatory support recognises economic disadvantages resulting from the roles adopted during the relationship.

For example, one spouse may have left paid employment to care for children while the other continued working and advanced professionally. The spouse who left employment may have lost earnings, pension contributions, professional experience, and future career opportunities.

The economic disadvantage may persist even after the children become independent. The spouse who remained in employment may have accumulated greater earning capacity and retirement savings.

In Moge v. Moge, [1992] 3 SCR 813, the Supreme Court of Canada emphasised the importance of recognising the economic consequences of marital roles and the unequal impact that relationship breakdown can have on spouses.

Compensatory support is not simply a reward for performing domestic work. It is an attempt to address the economic disadvantages associated with the division of responsibilities during the relationship.

9.2 Non-compensatory support

Non-compensatory support may be available where a spouse experiences financial need arising from the relationship breakdown, even where there is no clear career sacrifice or direct economic disadvantage attributable to marital roles.

In Bracklow v. Bracklow, [1999] 1 SCR 420, the Supreme Court recognised that spousal support may be justified by a relationship-based obligation arising from the circumstances of the marriage and the resulting financial need.

The decision demonstrates that support is not confined to cases where one spouse can prove a specific lost career opportunity. The parties’ mutual obligations and the economic consequences of their relationship may also be relevant.

9.3 Contractual support

A spouse may also be entitled to support under a valid agreement. The parties may have negotiated a support arrangement in a marriage contract, cohabitation agreement, or separation agreement.

However, the enforceability and interpretation of the agreement remain subject to applicable law. Courts may consider whether the agreement was properly negotiated, whether relevant disclosure occurred, and whether the statutory framework permits the particular terms to be enforced.

9.4 The Supreme Court’s approach

In Moge and Bracklow, the Supreme Court rejected an excessively narrow understanding of spousal support. The cases establish that entitlement may arise from different circumstances and that the legal analysis must reflect the economic realities of the relationship.

In Leskun v. Leskun, 2006 SCC 25, the Court confirmed that spousal support is not intended to punish misconduct. The economic consequences of conduct may be relevant where they affect a spouse’s ability to become self-sufficient, but moral blame is not the governing principle.

10. The Spousal Support Advisory Guidelines

The Spousal Support Advisory Guidelines (SSAG) are an important practical instrument in Canadian family law.

They were developed to improve consistency and predictability in determining the amount and duration of spousal support. They provide formulas that take account of factors such as:

• The parties’ incomes.
• The length of the relationship.
• Whether there are dependent children.
• The amount of child support.
• The parties’ ages and circumstances.
• The nature of the support claim.

The Guidelines are advisory rather than legislation. They do not create an automatic right to support, and they do not replace the statutory analysis required by the Divorce Act or provincial law.

Their role is to assist courts and parties once entitlement has been established or is not seriously disputed. They can help identify a reasonable range of support and provide a framework for negotiations.

10.1 Amount of support

Spousal support may be paid periodically, usually monthly, or as a lump sum. The appropriate structure depends on the circumstances.

Periodic payments may be appropriate where the recipient needs continuing financial assistance or where the parties’ financial circumstances may change over time.

A lump-sum payment may be appropriate where the parties wish to achieve a final financial settlement, where ongoing payments would be impractical, or where the parties can structure a transfer of assets to address the support obligation.

The choice of payment structure may also have tax consequences.

10.2 Duration of support

There is no universal rule that spousal support must end after a fixed number of years.

The duration may depend on:

• The length of the relationship.
• The age of the parties.
• The time required for the recipient to improve earning capacity.
• Childcare responsibilities.
• Health and employment circumstances.
• The compensatory basis of the claim.
• The terms of any agreement or court order.

Some awards are time-limited. Others may be indefinite, particularly after long relationships or where the recipient’s ability to become self-sufficient is limited.

Indefinite support does not necessarily mean support is payable for life without review. It may remain subject to variation, termination, or other statutory conditions.

10.3 Self-sufficiency

The Divorce Act recognises the objective of promoting self-sufficiency within a reasonable period where practicable.

However, self-sufficiency is not an absolute requirement that every recipient must immediately become financially independent. A court may recognise that a person cannot realistically restore a lost career, overcome long-term economic disadvantages, or obtain sufficient income while continuing to care for children.

The obligation must be understood in the context of the relationship’s history and the recipient’s actual circumstances.

11. Child Support: A Legal Right of the Child

Child support is one of the most important financial obligations arising from parental separation. Its purpose is to ensure that children continue to receive financial support from both parents even when the parents no longer live together.

Unlike spousal support, child support is not based on whether one parent sacrificed career opportunities or whether the relationship created an economic disadvantage. It arises from the legal responsibilities of parenthood.

A parent’s obligation to support a child is not extinguished by divorce, separation, the end of a common-law relationship, or the fact that the child primarily resides with the other parent.

11.1 Federal and provincial child-support legislation

The applicable child-support rules depend on the family’s circumstances.

The federal Divorce Act governs child support where married spouses are divorcing. The Federal Child Support Guidelines, made under the Act, establish the principal calculation framework.

Provincial and territorial legislation governs child support where parents were never married or where married parents separate without divorcing. These jurisdictions have their own legislation and guidelines.

There are also designated-province arrangements under which provincial guidelines apply in certain divorce cases where both parents live in the same designated province. New Brunswick, Manitoba, and Quebec have such arrangements.

The result is that the legal framework must be identified before calculating support. It is not sufficient to know only that the parents live in Canada. Ministère de la Justice+2

11.2 Who must pay child support?

Both parents have a legal responsibility to contribute to their child’s financial needs.

Where a child primarily resides with one parent, the other parent will generally pay support calculated under the applicable guidelines. The parent receiving the payment is not necessarily personally entitled to the money: the obligation exists for the benefit of the child.

Where parenting time is shared, the calculation may take account of both parents’ incomes and the amount of time the child spends with each parent.

The obligation is not determined by gender. A mother may be required to pay child support to a father, or a father to a mother. The relevant factors are the legal parent-child relationship, applicable parenting arrangements, income, and statutory rules.

11.3 Children entitled to support

Child-support legislation generally covers children who have not reached the age of majority, subject to the applicable statutory definition and circumstances.

In some situations, support may continue after the child reaches the age of majority. This may occur where the child remains dependent because of full-time education, disability, illness, or another legally recognised reason.

The precise test differs between the Divorce Act and provincial or territorial legislation. It is therefore incorrect to assume that child support always ends automatically on a child’s eighteenth or nineteenth birthday.

11.4 Child support and parenting arrangements

Parenting time and child support are separate legal questions.

A parent does not lose the right to receive child support simply because the other parent has contact with the child. Equally, a parent does not avoid child support merely because they have limited parenting time.

The child’s right to financial support is not a bargaining instrument to be exchanged for parenting time. A parent cannot lawfully treat access to the child as conditional upon payment, or refuse to pay support because the other parent has allegedly breached a parenting arrangement.

The law seeks to protect children from having their financial interests subordinated to disputes between adults.

12. Calculating Child Support Under the Federal Guidelines

The Federal Child Support Guidelines establish a structured method for calculating child support.

The principal components are:

1. The basic table amount.
2. Special or extraordinary expenses.
3. Adjustments for shared or split parenting arrangements.
4. The treatment of income and financial circumstances under the Guidelines.

12.1 The table amount

The basic amount is determined primarily by the paying parent’s annual income, the number of children, and the province or territory in which the parent ordinarily resides.

The Federal Child Support Tables provide monthly amounts corresponding to income and family size. Each province and territory has a separate table because tax rules and other financial factors differ.

The tables are intended to provide a predictable starting point and reduce the need for courts to calculate every case from first principles.

The Federal Child Support Tables were updated with effect from 1 October 2025, reflecting more recent tax information. The updated tables apply under the federal framework and have also been adopted in the provincial and territorial systems that use the Federal Tables, except Quebec, which has its own model.

12.2 Determining income

Income is central to child-support calculations.

The Guidelines generally use the concept of annual income, subject to statutory adjustments and special rules. The starting point is often income reported for income-tax purposes, but the court may adjust the figure where the tax return does not accurately reflect the parent’s financial circumstances.

Relevant income sources may include:

• Employment income.
• Self-employment income.
• Business income.
• Investment income.
• Rental income.
• Certain employment benefits.
• Pension income.
• Other financial resources recognised by the Guidelines.

A parent who owns a company may have a financial position that is not accurately represented by their declared salary. For example, the parent may receive shareholder benefits, retain profits in a corporation, or control the timing of distributions.

The Guidelines permit courts to address circumstances in which the ordinary income figure does not provide a fair picture of the parent’s resources.

12.3 Imputing income

A court may impute income where a parent’s reported income is not a reliable representation of their financial capacity or where the parent is intentionally avoiding their support obligations.

Potential grounds include:

• Unreasonable underemployment or unemployment.
• Deliberate income reduction.
• Failure to provide adequate financial information.
• Diversion of income through a corporation or another entity.
• Unreasonable deductions from business income.
• Other circumstances specified by the Guidelines.

Imputing income is not automatic whenever a parent earns less than the other parent considers appropriate. The court must examine the evidence, the parent’s circumstances, employment opportunities, health, caregiving responsibilities, and the applicable statutory provisions.

The objective is to prevent manipulation of income calculations while recognising legitimate reasons why a parent’s earnings may have declined.

12.4 Special and extraordinary expenses

The basic table amount does not necessarily cover every significant expense associated with raising a child.

Section 7 of the Federal Child Support Guidelines permits courts to make additional orders for qualifying special or extraordinary expenses. These may include:

• Childcare expenses required because of employment, illness, disability, or education.
• Medical and dental insurance premiums attributable to the child.
• Health-related expenses not covered by insurance.
• Extraordinary educational expenses.
• Post-secondary education expenses.
• Extraordinary extracurricular activities.

The expenses must meet the relevant statutory requirements. A parent cannot automatically classify every optional activity or ordinary household expense as an additional child-support obligation.

Courts generally consider the necessity and reasonableness of the expense, the child’s needs, the family’s previous spending patterns, and the financial means of the parents.

Where an expense is shared, the allocation is commonly based on the parents’ respective incomes after taking account of applicable contributions, subsidies, tax benefits, and other relevant factors.

12.5 Shared parenting arrangements

Where each parent exercises at least 40 per cent of parenting time over the course of a year, the shared-parenting provisions of the Federal Guidelines may apply.

The calculation is not necessarily a simple subtraction of one parent’s table amount from the other’s.

Under section 9, the court considers:

• The amounts that would otherwise be payable under the applicable tables.
• The increased costs of shared parenting arrangements.
• The conditions, means, needs, and other circumstances of each parent and the child.

The fact that parenting time is shared does not automatically eliminate child support. One parent may still earn substantially more than the other, and the child’s standard of living may differ significantly between households.

12.6 Split parenting arrangements

A split-parenting arrangement occurs where there are two or more children and each parent has primary care of at least one child.

The Guidelines provide a method that takes account of the amounts each parent would otherwise pay under the tables. The resulting calculation reflects the financial obligations running in both directions.

The method differs from the ordinary primary-residence model and should not be confused with shared parenting.

13. Child Support in Quebec

Quebec uses a distinctive child-support calculation model.

The system is based on the parents’ respective disposable incomes, the number of children, the basic parental contribution, and additional expenses.

The model is designed to recognise that both parents have an obligation to contribute to the child’s needs in proportion to their financial means.

The calculation generally involves:

1. Determining each parent’s annual income.
2. Calculating the disposable income of each parent under the applicable rules.
3. Establishing the basic parental contribution according to the number of children.
4. Allocating the contribution between the parents.
5. Taking account of parenting time and additional expenses.

Quebec’s model differs from the federal table system, although the underlying principle remains similar: both parents contribute to the financial support of their children.

The Civil Code of Québec and the provincial child-support determination framework must therefore be considered together when examining support obligations in Quebec.

14. Child Support, Spousal Support, and Financial Priority

A separation may involve simultaneous claims for child support and spousal support.

These obligations serve different purposes, but they interact because the paying parent has finite financial resources.

Under the Divorce Act, child support has priority over spousal support. Where the available income is insufficient to satisfy both obligations fully, the statutory framework gives priority to the child’s financial entitlement.

This principle reflects the special legal status of child support. A child should not be deprived of financial assistance because the parents are also disputing their respective financial positions.

The interaction can be especially important where one parent has a relatively low income but is responsible for supporting several children and a former spouse.

The court must consider the applicable guidelines, the parties’ financial means, and the statutory priority rules rather than treating the two obligations as entirely independent.

15. Variation, Review, and Termination of Support

Support arrangements are based on financial and personal circumstances that may change over time. Canadian family law therefore provides mechanisms for varying support orders and agreements.

15.1 Material changes in circumstances

A support order may be varied where the legal requirements for variation are satisfied. Depending on the type of support, a relevant change may include:

• A substantial increase or decrease in income.
• Job loss or a significant change in employment.
• Retirement.
• A serious illness or disability.
• A change in the child’s needs.
• A change in parenting arrangements.
• A child becoming financially independent.
• A change in the recipient’s financial circumstances.

The precise test depends on the applicable statute and the terms of the original order or agreement.

A party should not assume that a change in circumstances automatically changes the legal obligation. Unless the order or agreement provides otherwise, a variation may require a new agreement or court order.

15.2 Variation of child support

Child support may be varied where the legal requirements are met, including where income changes or the circumstances affecting the calculation have materially changed.

The updated Federal Child Support Tables that came into force on 1 October 2025 did not automatically amend every existing child-support order. However, the updated amount may be relevant when determining whether a change in circumstances justifies variation.

The Department of Justice explains that a party may seek a variation where the new table amount differs from the amount in an existing order and the difference is legally significant. Ministère de la Justice+1

Parents should also recognise that child support is not necessarily frozen at the amount originally agreed. Financial disclosure and periodic review may be necessary to ensure that support continues to reflect the parents’ actual circumstances.

15.3 Variation of spousal support

Spousal support may be varied where the applicable legal test is met. The original order or agreement is important because it may define the circumstances in which support can be reviewed or changed.

A recipient’s remarriage or entry into a new relationship does not automatically terminate spousal support in every case. The financial consequences of the new relationship, the terms of the order, and the legal principles governing variation must be considered.

Likewise, the paying spouse’s retirement does not necessarily end support. The court may examine whether retirement was reasonable, whether it was anticipated, and how the parties’ financial circumstances have changed.

15.4 Termination

Spousal support may terminate under the terms of an order or agreement, following a court decision, or upon the occurrence of a legally relevant event.

The death of a party, a specified end date, a review provision, or a material change may be relevant, depending on the terms and applicable law.

Child support generally ends when the child no longer falls within the statutory definition of a child entitled to support. However, post-majority dependency may extend the obligation.

16. Enforcement of Family Support Obligations

A support order is not merely a private promise. It is a legal obligation that can be enforced through statutory enforcement systems.

16.1 Provincial and territorial enforcement programs

Every province and territory has mechanisms for enforcing support obligations. These programs may be responsible for collecting payments, monitoring arrears, and taking enforcement action where a person fails to comply.

The precise procedures differ, but enforcement measures may include:

• Deductions from employment income.
• Garnishment of bank accounts.
• Seizure of certain assets.
• Registration of liens or charges.
• Interception of certain federal payments.
• Suspension or restriction of licences in legally authorised circumstances.
• Other statutory enforcement measures.

The federal Family Orders and Agreements Enforcement Assistance Act provides mechanisms that can assist with the enforcement of family support obligations, including certain federal tracing and interception measures.

16.2 Maintenance enforcement programs

A recipient may be able to register a support order or qualifying agreement with the provincial or territorial maintenance enforcement program.

Once registered, the program may collect payments and use authorised enforcement procedures. This can reduce the need for the recipient to pursue enforcement personally.

However, the existence of an enforcement program does not mean every payment dispute will be resolved immediately. Administrative procedures, objections, appeals, and jurisdictional questions may arise.

16.3 Arrears

Unpaid support can accumulate as arrears. A person who fails to pay support may face enforcement measures even where they believe their financial circumstances have changed.

A paying parent should not unilaterally reduce payments because of unemployment, illness, retirement, or a disagreement about parenting time. The appropriate legal route is to seek a variation or other relief under the applicable law.

A court may consider the reasons for non-payment, the parties’ conduct, the recipient’s circumstances, and the interests of the child when addressing arrears.

The Supreme Court of Canada considered the principles governing retroactive child support in D.B.S. v. S.R.G., 2006 SCC 37. The decision established that retroactive child support claims require a contextual analysis, including the circumstances of the child, the conduct of the payor, the recipient’s delay, and the hardship that retroactive relief may cause.

17. Tax Consequences of Property Division and Support

Although family-property and support law is principally concerned with civil obligations, tax treatment can affect the practical value of a financial settlement.

The tax consequences of property transfers and support payments are not identical.

17.1 Property transfers

Certain transfers of property between spouses or former spouses may qualify for tax-deferred treatment under the Income Tax Act, provided the statutory conditions are met.

However, a transfer that appears to be a simple division of assets may have tax implications if it involves capital property, corporate shares, investment accounts, or real estate.

The parties should distinguish between the market value of an asset and its after-tax economic value. A property worth $500,000 may not represent the same net financial benefit as an asset of equal market value that carries a substantial unrealised tax liability.

17.2 Spousal support

For many payments made under qualifying written agreements or court orders, periodic spousal support is generally deductible by the payer and included in the recipient’s taxable income under the applicable federal tax rules.

Lump-sum payments may receive different treatment. The legal character of the payment, the terms of the agreement or order, and the tax legislation must be examined.

17.3 Child support

Child support payments under the current tax framework are generally neither deductible by the payer nor taxable income to the recipient.

This treatment reflects the principle that child support is money provided for the child’s benefit rather than income transferred to the other parent for their personal use.

Because the tax consequences can be substantial, separation agreements should identify clearly which payments constitute spousal support, child support, property equalization, or another form of financial settlement.

18. Practical Example: A Marriage Breakdown Involving Property, Support, and Children

Consider a married couple who have lived together for fifteen years and have two children. One spouse has worked full-time throughout the marriage, while the other reduced employment to care for the children and manage most domestic responsibilities.

The family owns a home, two vehicles, retirement investments, and a small business. The spouses have a mortgage, personal debt, and different levels of retirement savings.

Following separation, several distinct legal questions arise.

18.1 Property division

The first task is to identify the applicable property regime. If the couple lives in Ontario, the calculation would generally involve each spouse’s net family property and the statutory equalization process.

The family home must be treated according to Ontario’s special matrimonial-home rules. The business and retirement investments must be valued, and relevant debts must be identified.

If the couple lives in British Columbia, the family-property and excluded-property framework would apply instead. If they live in Quebec, the family-patrimony regime and matrimonial regime would have to be examined.

The result could differ substantially depending on the jurisdiction.

18.2 Spousal support

The spouse who reduced employment may have a claim for compensatory spousal support because the division of responsibilities during the marriage affected their earning capacity and career development.

The court would consider the length of the marriage, the parties’ incomes, the role each performed, the financial consequences of childcare responsibilities, and the recipient’s prospects for self-sufficiency.

The Spousal Support Advisory Guidelines may assist in determining an appropriate range, but entitlement must first be established under the applicable law.

18.3 Child support

The parents must also determine child support. The basic calculation would depend on the applicable guidelines, their incomes, the number of children, and the parenting arrangement.

If the children primarily reside with one parent, the other parent will generally pay the applicable table amount, subject to the statutory rules.

If parenting time is shared, the court may apply the shared-parenting calculation. Additional expenses, such as childcare or certain educational and medical costs, may also have to be allocated.

18.4 Financial settlement

The parties may resolve the issues through a separation agreement. The agreement could provide that one spouse retains the family home, subject to refinancing and an appropriate financial adjustment, while the other receives investments or a lump-sum payment.

It could also establish periodic spousal support, child support, responsibility for extraordinary expenses, and a process for exchanging updated income information.

The example illustrates why family property, spousal support, and child support must be analysed separately even though they form part of one overall financial settlement.

20. Frequently Asked Questions

1. Is family property always divided equally in Canada?

No. The rules differ between provinces and territories. Some jurisdictions use equalization calculations, while others apply statutory distribution systems with different exclusions and judicial discretion. Quebec has its own family-patrimony and matrimonial-regime framework.

2. Does a spouse automatically receive half of everything owned by the other spouse?

No. Family-property legislation does not necessarily divide every asset in half. It establishes which property is included, what deductions or exclusions apply, and how the financial adjustment is calculated.

3. Does the spouse whose name is on the house automatically own it after separation?

Not necessarily. Legal title is important, but family-property legislation may create rights to the value of the property or special rights relating to occupation and disposition of the family home.

4. Is a house owned before marriage protected from division?

Not always. The treatment of premarital property differs between jurisdictions. Ontario, for example, has special rules for the matrimonial home that may prevent a spouse from deducting its value at the date of marriage.

5. Do common-law partners have the same property rights as married spouses?

Not throughout Canada. Some provinces provide property-sharing rights for qualifying common-law partners, while others require claims to be established through different legal principles. Quebec has historically treated de facto spouses differently, although its parental union regime introduced new rights for qualifying parents from June 2025.

6. Can an inheritance be excluded from family property?

Often, but not automatically. The applicable statute may require the inheritance to be traceable and may treat increases in its value differently. Using inherited funds for a family residence can have particular consequences.

7. Are pensions divided after divorce?

Pension rights accrued during a relationship may be included in the family-property calculation. The applicable statute and pension legislation determine how the value is assessed and whether benefits can be divided or transferred.

8. Can a family business be included in property division?

Yes. A business interest may be valued and included in the applicable calculation, even if only one spouse operates the business. The non-operating spouse does not necessarily become an owner or manager.

9. What is an equalization payment?

In a system such as Ontario’s, an equalization payment is generally a monetary payment designed to equalise the relevant net family property values of spouses. It does not necessarily involve dividing each asset physically.

10. Is spousal support automatic after divorce?

No. Entitlement depends on the applicable law and the circumstances of the relationship. A difference in income alone does not guarantee support.

11. Can a husband receive spousal support from his wife?

Yes. Spousal support is gender-neutral. Either spouse may be entitled to receive support if the legal requirements are satisfied.

12. Can a common-law partner claim spousal support?

In many provinces and territories, qualifying common-law partners may claim support. Eligibility depends on the applicable statutory definition and conditions. Quebec’s rules are different, particularly for de facto spouses who do not fall within the new parental union regime.

13. Does adultery affect spousal support?

Ordinarily, no. Canadian divorce law does not use spousal support to punish marital misconduct. The relevant issues are financial circumstances and the statutory objectives of support.

14. How long does spousal support last?

There is no universal duration. Support may be temporary, time-limited, reviewable, or indefinite, depending on the relationship, economic circumstances, and the terms of the order or agreement.

15. Are the Spousal Support Advisory Guidelines legally binding?

No. They are advisory tools that assist courts and parties in assessing appropriate amounts and durations. They do not replace the legal test for entitlement.

16. Who must pay child support after separation?

Both parents have a legal responsibility to support their children. The applicable guidelines determine how that responsibility is allocated, taking account of income and parenting arrangements.

17. Does a parent have to pay child support if they share parenting time equally?

Potentially, yes. Shared parenting does not automatically eliminate support. The calculation may consider both parents’ incomes, the costs of the arrangement, and the child’s circumstances.

18. At what age does child support end?

It depends on the applicable legislation and the child’s circumstances. Support may continue after the age of majority where the child remains dependent because of education, disability, illness, or another legally recognised reason.

19. Can parents agree that no child support will be paid?

They can negotiate arrangements, but they cannot conclusively waive the child’s legal entitlement. A court may scrutinise an agreement that does not adequately provide for the child.

20. Are extracurricular activities included in basic child support?

Ordinary expenses are generally reflected in the basic table amount. Qualifying special or extraordinary expenses may be allocated separately under the applicable guidelines.

21. What happens if a parent hides income to avoid child support?

A court may examine the parent’s financial records and, where justified, impute income. Deliberate underemployment, income diversion, or inadequate disclosure may affect the calculation.

22. Can child support be changed after a court order?

Yes, where the legal requirements for variation are met. A material change in income, parenting arrangements, or the child’s needs may justify a new order.

23. Can spousal support and child support be paid at the same time?

Yes. A person may be required to pay both. Under the Divorce Act, child support has priority where the paying spouse cannot meet both obligations fully.

24. What happens if a parent refuses to pay court-ordered support?

The recipient may use the relevant provincial or territorial maintenance enforcement program. Depending on the circumstances, enforcement measures may include income deductions, garnishment, asset seizure, and other statutory remedies.

25. Does a separation agreement have to be approved by a court?

Not necessarily. A properly executed agreement may be legally binding without a court order, subject to the applicable statutory requirements. However, converting or filing an agreement through the relevant legal procedure may be useful for enforcement, and child-support provisions remain subject to the child’s legal interests.

22. Conclusion

The financial consequences of relationship breakdown in Canada are governed by a complex interaction of federal, provincial, and territorial law. Property division, spousal support, and child support are related but legally distinct obligations, each serving a different purpose.

Property division addresses the economic interests accumulated during a relationship. Its precise operation depends on the applicable provincial or territorial regime, the parties’ legal status, the nature and value of their assets, and the statutory treatment of exclusions and liabilities. The differences between Ontario’s equalization system, British Columbia’s family-property framework, and Quebec’s family patrimony demonstrate why a single national explanation cannot replace jurisdiction-specific analysis.

Spousal support recognises that a relationship may create economic advantages and disadvantages that survive separation. It may compensate a spouse for career sacrifices, address financial need, or respond to the continuing consequences of childcare responsibilities. It is not a penalty for marital misconduct, nor is it an automatic entitlement based solely on income inequality.

Child support has a distinct and particularly important function. It protects the child’s right to financial support from both parents, regardless of the parents’ relationship status or personal disagreements. The federal and provincial guidelines seek to make that responsibility predictable, proportionate to parental means, and responsive to the child’s needs.

Ultimately, Canadian family law seeks to establish a fair financial framework after a relationship ends without treating the end of the relationship as the end of the responsibilities created during it. Understanding the applicable jurisdiction, distinguishing property claims from support claims, and ensuring complete financial disclosure are essential to reaching a lawful and workable settlement.
