Fault-Based Divorce Across the United States: State Variations, Procedure, and Legal Consequences

---

What Is Fault-Based Divorce?

Fault-based divorce is a form of marital dissolution in which the spouse seeking divorce alleges that the other spouse committed conduct recognized by state law as a legal ground for divorce.

Traditional fault grounds include conduct such as adultery, cruelty, desertion or abandonment, and certain forms of criminal conviction or imprisonment. Cornell Law School’s Legal Information Institute explains that fault divorce may be granted when one spouse proves that the other did something that resulted in the failure of the marriage, although the precise grounds differ from state to state.

For a useful general reference, see the Cornell Law School Legal Information Institute’s discussion of fault divorce and the traditional grounds for divorce.

The important feature of a fault system is therefore not simply that the marriage has ended. The petitioner must connect the dissolution to legally recognized misconduct.

That requirement distinguishes fault divorce from the modern no-fault model, under which a spouse generally asserts that the marriage has broken down without having to prove that the other spouse caused the breakdown.

Yet the modern American system is more complicated than a simple choice between “fault” and “no fault.”

In many jurisdictions, fault can disappear as a ground for dissolution while surviving as a consideration in alimony or other financial determinations.

That distinction is one of the most important features of contemporary American divorce law.

The United States Does Not Have One Fault-Divorce System

Divorce is primarily governed by state law. Consequently, the legal treatment of marital misconduct depends on the jurisdiction in which the divorce is filed.

The result is a national system containing several different models.

Model 1: No-Fault-Only Divorce

Some jurisdictions permit divorce only on no-fault grounds.

In these states, a spouse generally cannot obtain a divorce simply by alleging that the other spouse committed adultery, cruelty, abandonment, or another traditional fault.

The American Bar Association’s 2024 comparison of state statutes identifies jurisdictions in which the only statutory grounds for divorce are no-fault grounds such as irreconcilable differences or irretrievable breakdown.

Examples include:

• California
• Colorado
• Florida
• Hawaii
• Illinois
• Iowa
• Kentucky
• Maryland
• Michigan
• Minnesota
• Missouri
• Montana
• Nebraska
• Nevada
• North Carolina
• Oregon
• Washington
• Wisconsin
• Wyoming

The District of Columbia is also classified as no-fault-only in the ABA comparison.

This classification does not, however, mean that marital misconduct is legally irrelevant in every circumstance.

For example, the ABA chart notes that California is a no-fault-only jurisdiction while its alimony statute nevertheless contains provisions concerning domestic violence and certain criminal conduct. Florida similarly permits consideration of adultery and its economic consequences in determining alimony.

This illustrates why simply asking whether a state is a “fault state” can be misleading.

---

Model 2: Hybrid Fault and No-Fault Divorce

A much larger group of states allows a spouse to choose between no-fault and fault-based grounds.

In these jurisdictions, a petitioner may be able to allege that the marriage is irretrievably broken while also having the option of asserting specific misconduct.

The available grounds vary considerably.

For example:

• Georgia recognizes both fault and no-fault grounds, and its alimony law contains specific consequences for adultery and desertion.
• Texas recognizes no-fault divorce based on insupportability while also retaining fault grounds such as adultery and cruelty.
• Virginia recognizes fault grounds including adultery, felony conviction under specified circumstances, cruelty, and desertion, while also permitting divorce based on separation.
• Pennsylvania recognizes both fault and no-fault divorce and lists grounds including adultery, abandonment, cruel and barbarous treatment, bigamy, and imprisonment.
• South Carolina permits fault grounds while also recognizing a no-fault separation ground.

The existence of a fault option does not mean that most divorces in that jurisdiction necessarily proceed on fault grounds.

Instead, it means that the law preserves the possibility of using misconduct as the legal basis for dissolution where the statutory requirements are satisfied.

---

A Statistical View of the Modern American System

The numerical picture is useful because it shows how far American divorce law has moved away from the traditional fault-only model.

The ABA’s 2024 50-state comparison states that all states recognize some form of no-fault divorce. Its classification separately identifies states where fault remains an available ground and states where only no-fault grounds are available.

Using that classification, 19 states plus the District of Columbia fall into the no-fault-only category, while 31 states retain fault grounds alongside no-fault divorce.

That means that approximately:

• 38% of the 50 states are classified as no-fault-only;
• 62% of the states retain some fault-based ground.

This is an important statistic, but it should not be interpreted as meaning that 62% of American divorces are fault-based.

The statistic measures legal availability, not actual use.

A state may preserve adultery, cruelty, abandonment, or imprisonment as statutory grounds while most couples continue to use a no-fault ground.

The distinction between what the law permits and what divorcing spouses actually use is therefore essential.

---

Why the Number of “Fault States” Can Be Misleading

Lists of fault-divorce states frequently produce apparently contradictory results.

One source may identify approximately two-thirds of the states as retaining fault grounds, while another may identify a smaller or larger number.

There are several reasons.

First, states have different statutory structures.

Second, some states recognize special categories such as covenant marriage, which may impose different divorce requirements.

Third, some states permit misconduct to affect alimony or property while not recognizing misconduct as an independent ground for divorce.

Fourth, terminology differs.

A state may describe a ground as “cruel treatment,” “cruel and inhuman treatment,” “indignities,” “willful desertion,” “abandonment,” or another statutory formulation.

Consequently, counting states requires a definition of what qualifies as a “fault state.”

The safest approach is to examine the actual statute rather than rely exclusively on a generalized label.

---

The Most Common Fault Grounds

Although statutory language varies, several categories recur throughout American divorce law.

1. Adultery

Adultery is one of the classic fault grounds.

Cornell’s Legal Information Institute describes adultery in the divorce context as extramarital sexual intercourse involving a married person and someone who is not that person’s spouse.

The legal significance of adultery varies considerably.

In one state, adultery may simply establish grounds for divorce.

In another, it may potentially affect alimony.

In another, it may have limited or no relevance to property division.

The petitioner may also face evidentiary problems.

An accusation that a spouse had an affair is not necessarily equivalent to proving the statutory elements of adultery.

Evidence may include:

• admissions;
• communications;
• photographs;
• testimony;
• financial records;
• travel records;
• other circumstantial evidence.

The evidentiary requirements are state-specific.

---

2. Cruelty

Cruelty traditionally refers to conduct that makes continued marital life intolerable or unsafe.

Modern statutes may encompass physical abuse, serious threats, severe mental or emotional mistreatment, or other conduct defined by the particular jurisdiction.

Cornell’s Wex explains that cruelty in the divorce context has historically included the willful and persistent infliction of unnecessary physical or mental suffering.

The significance of the term is therefore highly dependent on case law.

A single unpleasant argument will generally not be equivalent to a statutory finding of cruelty.

At the same time, serious domestic violence can have consequences extending well beyond the divorce ground itself, including protective orders, custody determinations, and financial issues.

---

3. Abandonment and Desertion

Abandonment or desertion generally concerns the unjustified departure of one spouse from the marital relationship.

The precise elements vary.

A state may require proof of:

1. physical separation;
2. an intention to end marital cohabitation;
3. absence of consent;
4. absence of legal justification;
5. a specified period of time.

Some jurisdictions distinguish between actual desertion and forms of constructive desertion.

The terminology should therefore not be treated as nationally uniform.

Pennsylvania, for example, identifies abandonment of the marital home without reasonable cause for at least one year as a fault ground under its divorce statute.

---

4. Imprisonment or Felony Conviction

Some jurisdictions recognize incarceration or felony conviction as a ground for divorce.

The requirements can include:

• a conviction;
• a specified sentence;
• a minimum period of confinement;
• absence of reconciliation;
• or other statutory conditions.

The mere fact that one spouse has been arrested does not ordinarily satisfy such a ground.

The distinction between an arrest, conviction, and qualifying imprisonment can therefore be legally significant.

---

5. Substance Abuse

Some states recognize alcohol or drug abuse as a fault-based ground or as conduct relevant to another statutory ground.

Substance abuse may also become important independently of the divorce ground.

For example, evidence of severe substance abuse may become relevant to:

• child custody;
• visitation;
• financial misconduct;
• household expenses;
• marital property;
• spousal support;
• protective measures.

Consequently, the same evidence can have several different legal functions.

---

Fault as a Ground Versus Fault as a Financial Factor

This is perhaps the most important distinction in modern American divorce law.

A state can have:

No fault-based ground for divorce, but still permit consideration of certain misconduct when determining financial consequences.

The ABA’s 50-state comparison expressly warns that whether fault may be considered in granting a divorce is a separate question from whether conduct may be considered when awarding alimony or dividing property.

This means that a state should not automatically be classified as either “fault” or “no fault” for every legal purpose.

Example: California

California is classified as no-fault-only for purposes of obtaining a divorce.

Yet the ABA’s statutory analysis identifies provisions under which documented domestic violence and certain criminal convictions can affect spousal-support questions.

Example: Florida

Florida is also classified as no-fault-only.

Nevertheless, its alimony statute permits consideration of adultery and the economic consequences resulting from it.

Example: Georgia

Georgia permits fault-based divorce.

Its alimony statute goes further by providing that a spouse may be denied alimony where the separation was caused by that spouse’s adultery or desertion.

Example: Texas

Texas recognizes fault grounds while also permitting no-fault divorce based on “insupportability.”

Its maintenance statute expressly includes marital misconduct, including adultery and cruel treatment, among factors relevant to maintenance.

These examples demonstrate why the consequences of misconduct must be examined independently from the question of whether misconduct can establish the divorce itself.

---

A Comparative State Snapshot

Jurisdiction	Fault ground available?	No-fault divorce?	Can fault or misconduct matter in financial issues?
California	No	Yes	Yes, in specified circumstances
Colorado	No	Yes	Generally limited
Florida	No	Yes	Yes, particularly regarding adultery and economic consequences
Georgia	Yes	Yes	Yes
Illinois	No	Yes	Generally no fault factor in maintenance statute
Maryland	No	Yes	Yes, in specified alimony considerations
New York	Yes	Yes	Yes, in specified circumstances
North Carolina	No	Yes	Yes, particularly in alimony
Pennsylvania	Yes	Yes	Yes
South Carolina	Yes	Yes	Yes
Texas	Yes	Yes	Yes
Virginia	Yes	Yes	Yes
Washington	No	Yes	Generally limited
Wisconsin	No	Yes	Generally limited

The table illustrates a crucial principle: the legal effect of marital misconduct cannot be predicted solely from whether a state permits fault-based divorce. The ABA’s statutory comparison shows substantial differences among states concerning alimony and other consequences.

---

The Procedure: What Makes a Fault Divorce Different?

The general architecture of a divorce case remains familiar:

1. establishing jurisdiction;
2. satisfying residency requirements;
3. filing the petition or complaint;
4. serving the other spouse;
5. responding to the petition;
6. resolving temporary issues;
7. conducting discovery where necessary;
8. negotiating or mediating;
9. proceeding to trial if necessary;
10. obtaining a final judgment.

Fault-based divorce adds another layer:

The petitioner must establish the alleged fault under the applicable state law.

That additional issue can change the character of the litigation.

---

Step One: Choosing the Proper Jurisdiction

Before deciding whether to file on fault grounds, the petitioner must determine whether the chosen state court has authority to hear the divorce.

Residency rules vary significantly.

The ABA’s state-by-state comparison demonstrates that some jurisdictions require approximately six months of residence, while others have substantially shorter requirements or special exceptions.

This is especially important when spouses live in different states.

The state in which the marriage occurred is not automatically the state in which the divorce must be filed.

The relevant questions may include:

• Where does either spouse reside?
• How long has the spouse lived there?
• Where is the marital home?
• Where did the alleged misconduct occur?
• Where are the children located?
• Does the state have personal jurisdiction over the respondent?
• Does the state have jurisdiction over the relevant property?

Fault therefore does not replace ordinary jurisdictional analysis.

---

Step Two: Identifying the Statutory Ground

The petitioner must determine which statutory ground applies.

For example, the relevant state may permit:

• adultery;
• cruelty;
• abandonment;
• desertion;
• felony conviction;
• imprisonment;
• substance abuse;
• other specifically defined misconduct.

The petition should identify the legally recognized ground rather than simply describing the marriage as unhappy.

A general statement that a spouse behaved badly may not satisfy a statutory requirement.

---

Step Three: Pleading the Necessary Facts

A fault-based petition may require more factual specificity than a no-fault petition.

The petitioner may need to identify:

• the nature of the misconduct;
• when it occurred;
• where it occurred;
• the relationship between the misconduct and the marriage;
• any statutory waiting period;
• whether the conduct continued;
• whether the petitioner forgave or condoned the conduct;
• and other facts required by state law.

The level of detail required depends on the jurisdiction and the particular ground.

---

Step Four: Evidence and Discovery

This is where fault-based litigation can become significantly more complicated.

A no-fault divorce may require comparatively little evidence concerning why the marriage ended.

A contested fault case can require evidence concerning events occurring months or years earlier.

Discovery may involve:

• text messages;
• emails;
• photographs;
• financial records;
• medical records where legally obtainable;
• police reports;
• employment records;
• witness testimony;
• social-media evidence;
• deposition testimony;
• expert evidence in appropriate cases.

The admissibility of particular evidence remains governed by applicable procedural and evidentiary rules.

---

Step Five: Defenses to Fault Allegations

Historically, fault-based divorce systems developed a number of doctrines through which the respondent could challenge the petitioner’s entitlement to rely on misconduct.

Depending on the jurisdiction and the particular ground, concepts such as condonation, connivance, recrimination, collusion, or provocation may appear in historical or modern divorce law.

Their contemporary importance varies substantially.

A petitioner should therefore not assume that an old common-law defense automatically applies in a modern state court.

---

Step Six: Settlement and Mediation

A fault allegation does not necessarily require a trial.

The spouses may still resolve:

• property division;
• support;
• custody;
• parenting arrangements;
• debt;
• attorney-fee issues;
• and other financial matters through negotiation or mediation.

Indeed, a contested fault allegation may become one of the issues negotiated as part of a broader settlement.

The parties may agree on financial and parenting issues even when they disagree sharply about the underlying marital misconduct.

---

Step Seven: Trial and Proof

If the parties cannot resolve the dispute, the fault allegation may become a contested issue at trial.

The petitioner bears the burden imposed by the applicable state law.

The court may examine:

• documentary evidence;
• testimony from the spouses;
• third-party witnesses;
• expert evidence;
• communications;
• financial records;
• photographs or recordings where admissible;
• and other relevant evidence.

The precise burden and standard of proof depend upon state law.

The court may then determine whether the statutory ground has been established.

---

Why Fault-Based Divorce Can Take Longer

Fault litigation introduces an additional factual dispute into the divorce.

Instead of asking only:

“Has the marriage broken down?”

the court may have to ask:

“Did the alleged misconduct occur?”

and sometimes:

“Does that conduct satisfy the statutory definition of the particular fault ground?”

The parties may disagree over:

• whether an affair occurred;
• whether conduct constituted cruelty;
• whether a departure constituted abandonment;
• whether the statutory period has elapsed;
• whether the petitioner consented to or forgave the conduct;
• or whether the alleged conduct actually falls within the statutory definition.

The result can be greater discovery, more testimony, more motions, and potentially a longer trial.

This does not mean that every fault divorce is lengthy or contested. It means that the potential factual scope of the case is broader.

---

Does Proving Fault Mean You Get More Property?

Not necessarily.

This is one of the most persistent misconceptions about fault divorce.

A spouse who proves adultery, cruelty, or abandonment does not automatically receive a larger share of marital property.

Property-division systems differ.

Some states use equitable distribution.

Others use community-property principles.

Some statutes expressly limit the relevance of marital misconduct to property division, while others permit certain forms of misconduct or economic misconduct to be considered.

Therefore, the question should never simply be:

“Is this a fault state?”

Instead, the more useful question is:

“Does this state’s property-division law permit this particular type of misconduct to affect the property award?”

That is a much narrower and more legally accurate inquiry.

---

Does Fault Affect Alimony?

In some jurisdictions, yes.

This is one area in which marital misconduct can remain particularly significant.

The ABA’s 50-state comparison identifies numerous jurisdictions whose alimony statutes expressly permit consideration of fault or other non-economic conduct.

Examples include Georgia, Mississippi, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, and West Virginia, among others.

But the effect is not uniform.

A statute may:

• expressly list marital misconduct as a factor;
• distinguish economic misconduct from personal misconduct;
• focus on domestic violence;
• limit the relevance of adultery;
• impose restrictions on support for a spouse convicted of certain offenses;
• or leave considerable discretion to the court.

Thus, proving fault does not produce a nationally standardized financial result.

---

Does Fault Affect Child Custody?

Fault-based divorce should not be confused with a general rule that the “innocent spouse” automatically receives custody.

Modern custody decisions are generally structured around the best interests of the child and related statutory factors.

Nevertheless, misconduct can become relevant where it bears directly on parenting or the child’s welfare.

Examples can include:

• domestic violence;
• serious substance abuse;
• neglect;
• conduct creating a danger to the child;
• criminal behavior;
• or other circumstances demonstrating that a parent may pose a risk.

The fact that one spouse committed adultery, standing alone, does not necessarily establish that the spouse is an unfit parent.

The legal relevance of the misconduct must therefore be separated from moral judgment.

---

Fault-Based Divorce and Domestic Violence

Domestic violence deserves separate consideration because it can affect multiple parts of a family-law case simultaneously.

A history of violence may be relevant to:

• the availability of protective orders;
• custody;
• visitation;
• child safety;
• spousal support;
• attorney fees;
• and, in some jurisdictions, the divorce itself.

The legal system may therefore treat serious abuse differently from ordinary marital misconduct.

This is another reason why a simple list of “fault grounds” can obscure the more complicated legal consequences of the underlying conduct.

---

Covenant Marriage: A Special Category

A particularly unusual feature of American family law is the existence of covenant marriage in certain states.

Arizona, Arkansas, and Louisiana recognize special covenant-marriage regimes under which couples voluntarily enter a marriage subject to additional requirements concerning divorce. The ABA’s state comparison specifically notes that Arizona, Arkansas, and Louisiana have different divorce rules for covenant marriages.

This creates an important distinction.

The ordinary divorce rules applicable to a conventional marriage may not fully describe the options available to a spouse in a covenant marriage.

Consequently, someone researching fault divorce must first determine not only where the divorce is filed, but also what legal form of marriage exists.

---

Fault Divorce and the Problem of State-by-State Terminology

Legal terminology can make comparative research difficult.

One state may use:

• adultery;
• cruelty;
• abandonment.

Another may use:

• cruel and inhuman treatment;
• desertion;
• indignities.

A third may combine several concepts into a broader statutory category.

Therefore, two states may appear to have different laws while addressing similar conduct, or appear similar while actually imposing different elements.

For legal research, the statutory language and controlling case law matter more than the label attached to the ground.

---

Is Fault Divorce Faster Than No-Fault Divorce?

Sometimes, but there is no universal rule.

A fault ground can occasionally allow a spouse to avoid a separation period that would otherwise apply under a particular state’s no-fault procedure.

On the other hand, proving fault can create additional litigation that makes the case substantially longer.

The practical calculation therefore involves two competing possibilities:

Fault may eliminate a waiting requirement in some circumstances.

But:

Fault may also create an evidentiary dispute that takes longer to resolve.

The answer depends on the particular jurisdiction and facts.

---

Is Fault Divorce More Expensive?

It can be.

The additional costs may arise from:

• discovery;
• depositions;
• subpoenas;
• expert testimony;
• investigation;
• contested hearings;
• additional attorney time;
• evidentiary disputes;
• and trial preparation.

But cost should not be described as an inevitable consequence of fault divorce.

A case involving clear documentary evidence and an uncontested response may proceed relatively efficiently.

Conversely, even a nominally no-fault divorce can become expensive when spouses dispute property, support, custody, or business interests.

The degree of contest, rather than the label alone, is often the better predictor of litigation expense.

---

What Happens If the Petitioner Cannot Prove Fault?

The consequences depend on the state.

In a jurisdiction where a no-fault ground is independently available, failure to prove fault does not necessarily mean that the marriage must remain intact.

The petitioner may still be able to obtain a divorce under the applicable no-fault ground.

But the procedural consequences can differ where the petitioner has chosen a particular statutory route or where other disputed issues depend upon the fault allegation.

This is another reason why fault should not be treated as a universal national procedure.

---

Can a Divorce Be Stopped After It Begins?

The possibility of stopping a divorce also depends on the procedural stage and state law.

Before filing, there is obviously no court case to dismiss.

After filing, a petitioner may in some circumstances seek dismissal.

After service, however, the case is no longer entirely within the petitioner’s unilateral control. The respondent may have filed an answer, counterclaim, or other request for relief.

After a settlement has been reached, additional contractual and procedural questions may arise.

And once a final divorce judgment has been entered, reconciliation does not ordinarily undo the judgment. The parties generally would need to remarry if they wished to become spouses again.

The precise procedure for dismissal, withdrawal, settlement, or reopening of a case is governed by state law and court rules.

---

The Practical Decision: When Does Fault Actually Matter?

A spouse considering a fault-based filing should distinguish among three separate questions.

Question 1: Can I obtain a divorce on fault grounds?

This depends on whether the state recognizes the alleged conduct as a statutory ground.

Question 2: Can I prove the fault?

The existence of misconduct is not enough. The petitioner must satisfy the applicable evidentiary requirements.

Question 3: Will proving fault actually change the outcome?

This is perhaps the most important question.

If proving adultery will not affect property, support, custody, or timing in a meaningful way, pursuing an extensive fault case may provide little practical benefit.

If the misconduct has a legally recognized effect on alimony, property, custody, or another significant issue, the analysis may be different.

---

A Better Way to Compare Fault Divorce Laws

When comparing states, researchers should examine at least five separate variables:

Variable	Question
Divorce ground	Can misconduct itself establish the divorce?
Definition	What exactly constitutes the alleged fault?
Evidence	What must the petitioner prove?
Financial effect	Can misconduct affect property or support?
Family consequences	Can the conduct affect custody or protective orders?

This five-part framework is considerably more useful than simply labeling a state “fault” or “no fault.”

For example, a state can be no-fault-only for dissolution while still allowing evidence of domestic violence or adultery to influence particular financial questions.

---

Fault-Based Divorce in Historical Perspective

The modern American system represents a major transformation from the traditional model.

Historically, divorce was generally structured around the concept that one spouse had committed a legally recognized marital offense.

That model could make divorce difficult where neither spouse could prove legally sufficient misconduct.

The emergence of no-fault divorce changed the underlying legal philosophy.

Rather than requiring the state to determine which spouse caused the marriage to fail, no-fault systems generally allow the marriage to end once the statutory requirements for marital breakdown are satisfied.

Cornell’s Wex describes no-fault divorce as the modern dominant model and notes that every state now recognizes some form of no-fault divorce, while many have retained fault-based alternatives.

The surviving fault grounds are therefore remnants of an older system incorporated into a modern hybrid structure.

---

Why Fault Grounds Survive

The continued existence of fault grounds is not necessarily accidental.

Several legal considerations help explain their persistence.

First, some misconduct has consequences that extend beyond the mere fact that the marriage ended.

Second, legislatures may regard serious misconduct as relevant to financial support.

Third, fault grounds can sometimes provide an alternative to waiting or separation requirements.

Fourth, some spouses seek a formal judicial finding concerning serious misconduct.

Fifth, certain forms of misconduct may be independently relevant to children, financial resources, or safety.

The continuing existence of fault grounds therefore reflects more than a desire to preserve an older moral conception of marriage.

It can also reflect the practical consequences of misconduct within a family relationship.

---

Divorce Statistics Do Not Tell Us How Often Fault Is Used

The United States maintains extensive statistics concerning divorce rates, but those statistics should not be confused with statistics concerning the legal grounds used in individual divorce cases.

The CDC’s National Center for Health Statistics publishes state divorce rates and explains that the rate represents the number of divorces per 1,000 people living in the state.

However, national divorce-rate statistics do not establish how many divorces were filed on grounds of:

• adultery;
• cruelty;
• abandonment;
• imprisonment;
• or other fault grounds.

This distinction is important for researchers.

A state can have a high divorce rate without having a high rate of fault-based divorce.

Conversely, a state may preserve numerous fault grounds while most divorcing couples use no-fault procedures.

The existence of a statutory option therefore should not be interpreted as evidence of its frequency of use.

---

Frequently Asked Questions

Is fault-based divorce still legal in the United States?

Yes. Every state recognizes some form of no-fault divorce, but many states also retain fault-based grounds. The precise number depends on how the legal categories are defined and whether special marriage regimes are included. The ABA’s 2024 50-state statutory comparison identifies 31 states as permitting fault grounds in addition to no-fault grounds.

Which states allow fault-based divorce?

A substantial majority of states retain at least some fault-based grounds, although the exact grounds differ. Examples include Alabama, Alaska, Arizona, Connecticut, Georgia, New Jersey, New York, Pennsylvania, South Carolina, Texas, and Virginia. State statutes should be consulted because the list and legal classifications can change.

Is adultery a ground for divorce?

Adultery remains a traditional fault ground in jurisdictions that retain fault divorce. Whether it is available, how it is defined, what evidence is required, and what consequences it may produce depend on state law.

Is cruelty a ground for divorce?

Cruelty remains a fault ground in many jurisdictions that retain fault divorce. Its legal definition varies and may include serious physical or mental suffering, abuse, or other conduct making marital life legally intolerable.

Can fault affect alimony?

Yes, in some states. The ABA’s state-by-state comparison identifies numerous jurisdictions whose statutes permit fault or non-economic misconduct to be considered in alimony decisions.

Can adultery affect property division?

Potentially, but there is no national rule. Some jurisdictions consider particular forms of marital misconduct or economic consequences associated with misconduct, while others expressly limit the relevance of fault.

Does cheating automatically affect child custody?

No. Custody is generally determined according to the child’s best interests and applicable statutory factors. Adultery by itself does not automatically establish that a parent is unfit.

Is fault divorce more expensive?

It can be, because proving misconduct may require additional discovery, evidence, witnesses, and litigation. However, the cost of a divorce depends on the overall complexity and degree of dispute.

Is fault divorce faster?

Not necessarily. A fault ground may sometimes avoid a separation requirement, but proving fault can also substantially lengthen litigation.

Can a spouse refuse to grant a divorce?

In a modern no-fault system, one spouse’s refusal generally does not permanently prevent dissolution if the statutory requirements are satisfied. Fault-based systems historically gave greater importance to the respondent’s ability to contest the alleged misconduct, but contemporary state law varies.

Does every state have the same definition of abandonment?

No. The required period of separation, intent, justification, consent, and other elements differ by jurisdiction.

Can someone file for divorce in a state where the spouse does not live?

Possibly. Divorce jurisdiction depends on state residency, domicile, personal jurisdiction, and other statutory requirements. A spouse should not assume that the state where the marriage occurred is automatically the proper forum.

Does a fault finding mean the innocent spouse automatically receives more money?

No. Financial consequences depend on the state’s property and support laws. Some states give misconduct substantial significance in particular circumstances, while others largely exclude it.

Key Takeaways

• Every U.S. state recognizes some form of no-fault divorce, but states differ substantially in whether they also permit fault-based grounds.
• The American Bar Association’s 2024 50-state statutory comparison classified 19 states plus the District of Columbia as no-fault-only jurisdictions, while the remaining states retained some form of fault ground.
• Common fault grounds include adultery, cruelty, abandonment or desertion, felony conviction or imprisonment, and other forms of serious marital misconduct.
• A state may prohibit fault as a ground for obtaining a divorce while still allowing certain misconduct to influence alimony, property-related decisions, or other financial consequences.
• Fault-based divorce generally requires more factual proof than a no-fault divorce because the spouse asserting fault must establish the statutory ground.
• The exact definition of adultery, cruelty, abandonment, and other grounds differs considerably among states.
• Filing on fault grounds does not automatically mean that the court will award the innocent spouse more property, more support, or a different custody arrangement.
• Residency, jurisdiction, waiting periods, evidentiary requirements, and available defenses remain matters of state law.
• A divorce based on fault should therefore be analyzed as a state-specific legal procedure, not as one uniform national process.

Conclusion

Fault-based divorce remains an important part of American family law, but it no longer represents the basic structure of divorce throughout the United States.

The modern system is better understood as a spectrum of state approaches.

At one end are jurisdictions that permit divorce only on no-fault grounds. At the other are states that preserve traditional fault grounds alongside no-fault procedures. Between those categories are numerous variations concerning adultery, cruelty, abandonment, imprisonment, domestic violence, economic misconduct, alimony, and property.

The most important lesson is therefore that “fault divorce” is not a single national procedure.

The legal analysis must distinguish between:

• the ground for obtaining the divorce;
• the conduct that must be proved;
• the evidentiary requirements;
• the effect of misconduct on alimony;
• the effect on property;
• the possible relevance to custody;
• residency and jurisdiction;
• and the procedural consequences of choosing a fault-based route.

For anyone researching divorce law in the United States, the correct starting point is consequently not simply the question, “Is fault divorce legal?”

The more precise questions are:

What fault grounds does this state recognize? What must be proved? And what legal consequences can follow if the misconduct is established?

That state-specific approach provides a far more accurate picture of modern American divorce law than a simple fault-versus-no-fault classification.
