Confidentiality

Confidentiality and Privileged Communications

Confidentiality and privileged communications are closely related concepts in the law of evidence, but they are not identical. Both concern the protection of information shared in circumstances in which the law recognizes an interest in keeping the information from disclosure. Yet the legal consequences of confidentiality and privilege can be very different.

A communication may be confidential without being legally privileged. Conversely, a communication may qualify for an evidentiary privilege because it satisfies the specific requirements of a recognized legal doctrine. The distinction becomes particularly important when a party is asked to disclose information during discovery, at a deposition, under subpoena, or at trial.

Confidentiality generally concerns an expectation or legal duty that information will not be disclosed to unauthorized persons. Privilege is an evidentiary protection that can prevent compelled disclosure of qualifying communications or information in legal proceedings. Cornell’s Legal Information Institute describes privileged communication as a confidential exchange that is legally protected from compelled disclosure, subject to applicable exceptions and waiver.

The difference is fundamental:

Confidentiality concerns keeping information private; privilege concerns the legal ability to resist compelled disclosure.

The two concepts frequently overlap, but they should not be treated as interchangeable.

What Is Confidentiality?

Confidentiality generally refers to an obligation, expectation, or legal protection against unauthorized disclosure of information.

A communication may be confidential because the participants intend it to remain private, because a professional relationship imposes a duty of confidentiality, because a contract requires confidentiality, or because a statute protects the information.

Confidentiality can therefore arise in many contexts.

A lawyer may owe confidentiality to a client. A physician may have legal and professional obligations concerning patient information. A business may have contractual obligations concerning confidential information. An employee may have duties concerning proprietary information. A mediator may be subject to confidentiality requirements governing mediation communications.

Not all of these protections are evidentiary privileges.

The fact that information is confidential does not automatically mean that a court can never compel its disclosure.

What Is a Privileged Communication?

A privileged communication is a communication that falls within a recognized legal privilege protecting it from compelled disclosure.

The privilege may arise under federal common law, state law, statute, constitutional principles, or another recognized legal source.

Attorney-client privilege is a classic example. It generally protects qualifying confidential communications between a lawyer and client made for the purpose of obtaining or providing legal advice.

The protection can extend to many forms of communication, including:

  • oral conversations;
  • letters;
  • emails;
  • text messages;
  • memoranda;
  • electronic communications; and
  • other qualifying exchanges.

The form of communication is usually less important than the relationship, purpose, confidentiality, and circumstances surrounding the communication.

Confidentiality Does Not Automatically Create Privilege

One of the most important rules to understand is that confidentiality alone does not create an evidentiary privilege.

Imagine that two business partners have a private conversation about a dispute with another company.

They may reasonably expect the conversation to remain private. Nevertheless, that expectation does not automatically create an evidentiary privilege.

If one of the partners is later subpoenaed, the court must determine whether some recognized privilege actually protects the communication.

The same principle applies to private conversations between friends, family members, coworkers, or business associates.

Privacy is not the same thing as legal privilege.

The Relationship Between Confidentiality and Privilege

Although they are different concepts, confidentiality is often an essential component of a privilege.

For example, attorney-client privilege generally depends upon the communication being made confidentially in the context of the attorney-client relationship.

If a client intentionally makes a communication in front of an unrelated third party, the circumstances may demonstrate that confidentiality was not intended or maintained.

The loss of confidentiality can therefore destroy or prevent the privilege.

This produces an important distinction:

Confidentiality may be necessary for privilege, but confidentiality by itself is not sufficient to create privilege.

Why Does the Law Protect Confidential Communications?

The law protects certain confidential communications because some relationships depend upon candid communication.

Consider the attorney-client relationship.

A client may need to tell a lawyer facts that are embarrassing, damaging, complicated, or potentially adverse to the client’s interests. If every communication could later be compelled by an opposing party, clients might withhold information from their lawyers.

The attorney might then be unable to provide accurate legal advice.

The Supreme Court has repeatedly recognized this rationale. In Upjohn Co. v. United States, the Court explained that attorney-client confidentiality encourages clients to make full and frank disclosures, enabling lawyers to provide candid advice and effective representation.

The law therefore accepts a limited loss of evidence in order to promote relationships that serve broader legal and social purposes.

Confidentiality Versus Evidentiary Privilege

The distinction can be illustrated through several questions.

Suppose a lawyer receives confidential information from a client.

The first question may be:

Does the lawyer have a duty not to disclose the information?

That is a confidentiality question.

A second question may be:

Can an opposing party compel the lawyer to reveal the information in litigation?

That is an evidentiary privilege question.

A third question may be:

Can the lawyer disclose the information with the client’s consent?

That may depend on the applicable professional-conduct rules and the scope of the client’s consent.

A fourth question may be:

Has the client waived the evidentiary privilege by voluntarily disclosing the communication?

That is a privilege and waiver question.

The answers to these questions do not necessarily coincide.

Attorney Confidentiality Is Broader Than Attorney-Client Privilege

The distinction is especially important in the legal profession.

An attorney’s duty of confidentiality is broader than the evidentiary attorney-client privilege.

The attorney’s professional duty generally concerns information relating to the representation of a client and can apply even when no litigation is pending and no court is demanding disclosure.

Cornell’s discussion of the attorney’s duty of confidentiality distinguishes it from attorney-client privilege by explaining that the professional duty operates throughout the attorney-client relationship and afterward, rather than only when a legal demand for disclosure arises.

For example, a lawyer may have a professional duty not to disclose information learned from a client even though the particular information would not qualify for the evidentiary attorney-client privilege.

This distinction matters because lawyers must analyze both questions independently:

Is disclosure professionally prohibited?

and

Is the information protected from compelled disclosure under an evidentiary privilege?

The Attorney-Client Privilege

Attorney-client privilege protects qualifying confidential communications between a lawyer and client concerning legal advice or legal services.

The privilege is designed to encourage candid communication between clients and lawyers.

A communication generally must satisfy several requirements before the privilege applies.

The parties must have the appropriate relationship. The communication must generally be confidential. It must ordinarily concern legal advice or legal services. And no exception or waiver may defeat the privilege.

The privilege generally belongs to the client.

A lawyer therefore cannot simply decide that a privileged communication should be disclosed because the lawyer personally believes disclosure would be useful.

The client’s privilege must be respected unless an applicable exception, waiver, legal requirement, or other governing doctrine permits or requires disclosure.

Privilege Protects Communications, Not Everything About the Relationship

A common misconception is that once a lawyer becomes involved, everything concerning the client becomes privileged.

That is not the law.

Attorney-client privilege generally protects qualifying communications, not every fact relating to the client.

Suppose a client tells a lawyer:

“I was at the warehouse at 8:00 p.m.”

The communication to the lawyer may be privileged if it satisfies the requirements of the attorney-client privilege.

But the underlying fact that the client was at the warehouse is not necessarily privileged merely because the client communicated it to the lawyer.

The opposing party may be able to discover that fact from another source.

Privilege therefore does not ordinarily allow a person to make an independently discoverable fact disappear simply by telling it to a lawyer.

Confidentiality and the Purpose of the Communication

The purpose of a communication can determine whether privilege applies.

Consider a company executive who sends an email to the company’s lawyer.

The email might ask:

“What are our legal obligations under this contract?”

That communication is directed toward legal advice.

But another email might say:

“Please prepare the quarterly sales report.”

The fact that the recipient happens to be a lawyer does not automatically make the communication privileged.

Lawyers often perform business, administrative, financial, managerial, and other functions in addition to providing legal advice.

The privilege generally concerns communications made for the purpose of obtaining or providing legal advice rather than communications that merely happen to involve a lawyer.

Dual-Purpose Communications

Modern professional relationships often produce communications serving more than one purpose.

A client may ask a lawyer to provide legal advice concerning a business transaction. The same communication may also involve commercial, financial, tax, regulatory, or strategic considerations.

These are sometimes called dual-purpose communications.

Courts have developed different approaches for determining whether such communications fall within attorney-client privilege.

The question can become particularly difficult when legal and non-legal functions are intertwined.

The mere presence of a legal issue does not automatically make every communication privileged.

The precise governing test can depend on the jurisdiction and circumstances.

This issue illustrates why privilege cannot be determined simply by asking whether a lawyer was involved.

Confidentiality and Third Parties

The presence of a third party can have significant consequences for confidentiality and privilege.

Suppose a client privately communicates with a lawyer.

The communication may qualify for attorney-client privilege.

Now suppose the client invites an unrelated friend into the room and discusses the same subject.

The third person’s presence may demonstrate that the communication was not intended to remain confidential and may destroy or prevent the privilege.

But third-party participation does not automatically defeat privilege in every circumstance.

Some third parties may be necessary to facilitate the attorney-client relationship.

An interpreter, for example, may be essential to communication between lawyer and client.

Similarly, certain agents, employees, consultants, or other representatives may participate in a protected communication when their involvement is necessary to facilitate legal advice.

The question is whether the third party is consistent with the confidential relationship and the purpose of the privilege.

Confidentiality in Digital Communications

Modern communications create additional challenges.

Attorney-client communications may occur through:

  • email;
  • text messages;
  • secure client portals;
  • videoconferencing;
  • messaging applications;
  • cloud-based document systems;
  • shared electronic workspaces; and
  • other digital platforms.

The fact that communication is electronic does not automatically destroy privilege.

But digital communication can create additional risks.

A message may be copied to unnecessary recipients. An email may be forwarded outside the protected relationship. A document may be uploaded to an inappropriate platform. A shared device may expose confidential information to someone who is not part of the protected relationship.

The underlying principle remains the same: confidentiality depends on the circumstances and the reasonable preservation of the protected relationship.

Confidentiality and Accidental Disclosure

Accidental disclosure creates a particularly important distinction between confidentiality and privilege.

Suppose a lawyer inadvertently sends a privileged email to the wrong recipient.

The mistake may compromise confidentiality, but the legal consequences depend on the governing rules.

Federal Rule of Evidence 502 provides specific protections concerning certain inadvertent disclosures of attorney-client privileged and work-product material.

Under Rule 502(b), an inadvertent disclosure does not result in waiver in circumstances where the disclosure was inadvertent, reasonable steps were taken to prevent disclosure, and reasonable steps were promptly taken to rectify the error. The precise application depends on the circumstances and governing law.

Thus, an accidental disclosure should not automatically be treated as equivalent to an intentional decision to abandon privilege.

Waiver of Privilege

A privilege may be waived.

Waiver generally occurs when the holder of the privilege acts inconsistently with maintaining the protection.

Voluntarily disclosing a privileged communication to an unnecessary third party is a classic example.

For instance, if a client deliberately forwards a confidential attorney email to an unrelated business associate, that disclosure may affect the privilege.

Waiver can also arise when a party selectively discloses privileged communications while attempting to prevent disclosure of other communications concerning the same subject.

The precise scope of waiver varies according to the privilege and applicable law.

Confidentiality and Waiver Are Not Identical

A useful distinction is that confidentiality concerns the circumstances under which information is maintained as private, while waiver concerns the legal consequences of conduct that relinquishes a privilege.

A communication can be confidential but not privileged.

A privileged communication can lose protection through waiver.

And a disclosure can potentially affect confidentiality without necessarily producing every consequence associated with waiver.

The legal analysis therefore requires identifying the specific protection involved rather than using “confidential” and “privileged” as interchangeable labels.

Confidentiality in the Medical Context

Medical relationships provide another useful example.

Patients generally have strong legal and ethical interests in keeping medical information confidential.

But medical confidentiality and physician-patient privilege are not the same thing.

Physician-patient privilege is primarily a matter of state law in the United States. The Federal Rules of Evidence do not create a general federal physician-patient privilege. By contrast, federal common law recognizes a psychotherapist-patient privilege.

Medical information can also be protected by statutes and regulations concerning privacy.

HIPAA, for example, regulates the use and disclosure of protected health information in circumstances covered by the statute. It should not simply be equated with a universal evidentiary privilege.

Thus, a person should not assume that:

medical information = privileged evidence

The applicable legal protection must be identified separately.

Confidentiality and Psychotherapist-Patient Communications

Mental-health communications provide another important example of the relationship between confidentiality and privilege.

The federal psychotherapist-patient privilege protects certain confidential communications between a patient and a qualifying mental-health professional.

The Supreme Court recognized this federal privilege in Jaffee v. Redmond, emphasizing the importance of confidential communications to effective psychotherapy.

Again, however, the existence of a professional relationship does not mean that every piece of information associated with that relationship receives identical protection.

The communication, purpose, participants, confidentiality, and applicable exceptions must be examined.

Confidentiality and Spousal Communications

Spousal communications provide another illustration.

Some jurisdictions recognize a marital communications privilege protecting qualifying confidential communications between spouses.

The privilege is concerned with the communication itself rather than simply the fact that the speakers are married.

A private communication may therefore receive protection that an openly made statement does not.

At the same time, spousal privileges vary significantly among jurisdictions, and different doctrines may govern confidential communications and compelled testimony by a spouse.

Marriage alone therefore does not establish that every communication between spouses is privileged.

Confidentiality in Mediation

Confidentiality can also play an important role in mediation and other dispute-resolution processes.

Parties are often encouraged to speak openly during settlement discussions.

If participants believed that every statement made during mediation could later be introduced against them, they might be less willing to negotiate honestly or explore potential compromises.

For that reason, statutes, court rules, regulations, contracts, or procedural rules may protect mediation communications from disclosure.

The exact protection varies by jurisdiction and by the type of proceeding.

Confidentiality in mediation therefore demonstrates another important principle: a legal system can protect communications through rules other than traditional evidentiary privilege.

Confidentiality and Settlement Negotiations

Settlement negotiations provide another important example.

Federal Rule of Evidence 408 generally restricts the use of certain statements and offers made during compromise negotiations when offered to prove or disprove the validity or amount of a disputed claim.

This is not simply a traditional evidentiary privilege.

Instead, Rule 408 is an evidentiary exclusionary rule addressing the use of particular compromise-related evidence.

This distinction matters because different legal doctrines can protect information for different reasons.

Some rules protect communications because of a confidential relationship. Others restrict evidence because admitting it would undermine public policies such as encouraging settlement.

Confidentiality and Work Product

Confidentiality can also intersect with the attorney work-product doctrine.

Work product generally protects qualifying materials prepared in anticipation of litigation or for trial.

The doctrine is different from attorney-client privilege.

A lawyer’s litigation strategy memorandum, for example, may reveal the lawyer’s mental impressions and legal theories. It may receive work-product protection even though it is not a communication between lawyer and client.

Cornell’s discussion of attorney work product distinguishes opinion work product, including an attorney’s mental impressions and legal theories, from ordinary work product.

Confidentiality can therefore be relevant to the handling of work-product materials without being the source of the protection itself.

Confidentiality and Discovery

The distinction between confidentiality and privilege becomes especially important during discovery.

Discovery rules generally permit parties to obtain relevant information within the scope of discovery, subject to applicable limitations and protections.

A party cannot ordinarily resist discovery merely by labeling a document “confidential.”

The party must identify a recognized legal basis for withholding it.

That basis might be:

  • attorney-client privilege;
  • work-product protection;
  • a statutory privilege;
  • a constitutional protection;
  • a protective order;
  • a specific discovery limitation; or
  • another recognized legal doctrine.

The word “confidential” on a document therefore does not itself create a privilege.

Confidential Documents and Protective Orders

Courts can also issue protective orders governing sensitive information.

A protective order may restrict how discovery material is used, who may access it, or whether it may be disclosed publicly.

A protective order is not necessarily the same as an evidentiary privilege.

A document may be subject to a protective order while remaining discoverable.

For example, the court might permit discovery of sensitive business information but restrict its use to the litigation and limit public disclosure.

Privilege, by contrast, may prevent the information from being compelled in the first place.

Confidentiality and Public Disclosure

Once information becomes publicly known, the analysis can change substantially.

Many confidentiality-based protections depend upon the information remaining confidential.

If a client voluntarily publishes a previously confidential communication, for example, the circumstances may undermine a claim that the communication remains confidential.

However, public availability does not automatically resolve every privilege issue.

Different doctrines protect different interests, and the consequences of disclosure depend on the particular privilege, the manner of disclosure, and applicable law.

Confidentiality and Privilege in Corporate Communications

Corporate environments make confidentiality particularly complicated.

A corporation may have lawyers, executives, employees, accountants, consultants, investigators, and outside professionals participating in a single project.

A document may be marked “Attorney-Client Privileged and Confidential,” but the label alone does not determine whether privilege exists.

Courts examine the substance and circumstances of the communication.

Relevant questions can include:

Who created the communication?

Who received it?

Was counsel acting as legal counsel?

What was the purpose of the communication?

Was the communication intended to remain confidential?

Were the recipients necessary to obtain or provide legal advice?

Was the communication later disclosed outside the protected group?

These questions are much more important than the title placed at the top of a document.

Confidentiality Does Not Mean Absolute Secrecy

Even genuine professional confidentiality is rarely absolute.

Legal systems recognize circumstances in which disclosure may be permitted or required.

For lawyers, professional rules may permit disclosure in specified circumstances, such as preventing certain serious harm, complying with law or court order, defending the lawyer against allegations, or other circumstances recognized by the applicable professional rules.

The exact exceptions vary by jurisdiction and governing ethical code.

Cornell’s discussion of attorney confidentiality identifies several circumstances in which disclosure may be permitted under professional-conduct rules.

The existence of exceptions does not make confidentiality meaningless. It means that confidentiality is a legal duty with defined boundaries rather than an absolute prohibition on disclosure under every circumstance.

Confidentiality After the Professional Relationship Ends

Confidentiality obligations can survive the end of the relationship that created them.

For example, a lawyer’s duty of confidentiality generally continues after representation ends.

The termination of an attorney-client relationship therefore does not ordinarily mean that the lawyer becomes free to disclose information previously obtained through the representation.

The same principle can apply in other professional relationships depending on the governing law.

The continued existence of a confidentiality obligation after termination demonstrates again that professional confidentiality is broader than an evidentiary privilege tied to a particular proceeding.

Confidentiality After Death

Certain privilege protections can also survive the death of the person who held the privilege.

Attorney-client privilege provides an important example.

In Swidler & Berlin v. United States, the Supreme Court recognized the continuing force of attorney-client privilege after a client’s death in the circumstances before the Court.

The rationale included the importance of assuring clients that their communications with counsel will remain confidential, thereby encouraging candid communication in the first place.

The survival of a particular privilege after death depends on the doctrine involved and applicable law.

Who May Assert Privilege?

The identity of the privilege holder depends upon the particular privilege.

Attorney-client privilege generally belongs to the client.

Some privileges belong to patients or other protected individuals.

Certain privileges may involve shared or specially defined rights.

This distinction matters because the holder ordinarily has the authority to assert or waive the protection.

The person who happens to possess the information is not necessarily the person who controls the privilege.

Privilege and Compelled Testimony

A privileged communication may be protected when a witness is asked to disclose it in court.

The protection can arise in several procedural settings.

A party may assert privilege:

  • in response to a subpoena;
  • during discovery;
  • during a deposition;
  • in response to interrogatories;
  • during document production;
  • during testimony at trial; or
  • in another proceeding involving compelled disclosure.

The precise procedure for asserting privilege varies.

But the basic concept remains the same: a valid privilege can prevent otherwise relevant information from being compelled.

Privilege and the Duty to Preserve Evidence

Privilege should also be distinguished from the duty to preserve potentially relevant evidence.

A party generally cannot destroy evidence merely because the evidence is confidential or potentially privileged.

Privilege concerns whether protected information must be disclosed.

Preservation concerns whether potentially relevant evidence must be retained.

A party may therefore have a duty to preserve a privileged document even though the document ultimately will not have to be produced because it is privileged.

This distinction becomes particularly important in electronic discovery.

Privilege Logs and Confidentiality

During litigation, a party may withhold documents on privilege grounds while identifying them in a privilege log.

The purpose is to allow the opposing party and court to evaluate the claim without revealing the protected substance.

A document may therefore be described without disclosing the very communication that the privilege protects.

The requirements for privilege logs vary by jurisdiction, court rules, and procedural orders.

When Confidentiality Is Lost

Confidentiality may be undermined when information is voluntarily disclosed outside the protected relationship.

Common examples include:

  • forwarding a privileged email to an unrelated third party;
  • discussing a privileged legal consultation publicly;
  • posting confidential information online;
  • distributing confidential documents to unnecessary recipients;
  • allowing unauthorized persons access to protected communications.

But accidental disclosure requires a more careful analysis.

The legal consequences depend on the applicable privilege and waiver rules, and federal Rule 502 provides specific protections for certain inadvertent disclosures involving attorney-client privilege and work product.

The Importance of Intent

Intent often matters in confidentiality analysis.

A communication generally must be intended to remain confidential for many privileges to apply.

For example, a statement made loudly in a public location where unrelated people can easily hear it may not have the same confidential character as a private conversation.

The question is not always whether someone could theoretically have overheard the communication. Courts may examine the circumstances and whether the participants reasonably intended confidentiality.

Confidentiality is therefore a contextual concept.

The Importance of Purpose

Purpose is equally important.

A communication with a lawyer may involve legal matters but still be primarily commercial or administrative.

A communication with a physician may concern something unrelated to medical treatment.

A communication between spouses may concern a matter unrelated to the marital relationship.

The legal protection depends on the specific doctrine and its purpose.

Courts therefore generally examine what the communication was actually intended to accomplish rather than relying solely on the identities of the participants.

A Practical Framework for Analyzing Confidentiality and Privileged Communications

When evaluating a potentially protected communication, a structured analysis is useful.

Identify the Communication

Determine exactly what information is being protected.

Is it an oral statement, email, text message, memorandum, medical record, legal document, recording, or other material?

Identify the Participants

Determine who communicated with whom.

The identities and relationships of the participants can determine whether a privilege is even potentially available.

Identify the Purpose

Ask why the communication occurred.

Was it for legal advice, medical treatment, psychotherapy, marital communication, litigation preparation, settlement, business administration, or another purpose?

Determine Whether Confidentiality Was Intended

Examine whether the participants intended the communication to remain confidential.

Consider the setting, recipients, communication method, and circumstances.

Determine whether the protection comes from:

  • evidentiary privilege;
  • professional confidentiality;
  • statute;
  • constitutional law;
  • contract;
  • protective order; or
  • another doctrine.

Examine Third-Party Participation

Determine whether additional people participated.

Then ask whether their participation was necessary or consistent with maintaining confidentiality.

Check for Exceptions

Determine whether an exception applies.

For attorney-client communications, for example, crime-fraud principles may become relevant.

Check for Waiver

Determine whether the person holding the protection voluntarily disclosed the information or otherwise acted inconsistently with confidentiality.

Determine the Scope

Finally, determine exactly what is protected.

The protection may cover a communication without protecting the underlying facts.

Common Misunderstandings

“Confidential means privileged.”

Not necessarily.

A confidential communication may lack any recognized evidentiary privilege.

“If I tell my lawyer something, it is automatically privileged.”

Not necessarily.

The communication must satisfy the requirements of attorney-client privilege, including its relationship and purpose requirements.

“Everything in a lawyer’s file is privileged.”

No.

A lawyer’s file may contain privileged communications, work product, discoverable factual material, public documents, administrative records, and other information subject to different rules.

“A confidentiality label creates privilege.”

No.

Writing “CONFIDENTIAL” or “ATTORNEY-CLIENT PRIVILEGED” on a document does not itself establish privilege.

“HIPAA makes all medical information privileged.”

No.

HIPAA and evidentiary privilege are different legal regimes. Physician-patient privilege is primarily a matter of state law, while federal law recognizes a psychotherapist-patient privilege.

“Privilege protects the underlying facts.”

Generally, no.

Privilege usually protects qualifying communications or materials rather than independently existing facts.

“Privilege can never be waived accidentally.”

Not necessarily.

Accidental disclosure can create difficult waiver questions, but federal Rule 502 provides specific protection for certain inadvertent disclosures when its requirements are satisfied.

“A court cannot ever see privileged material.”

Not necessarily.

Courts may conduct procedures such as in camera review when necessary to resolve a privilege dispute. The review itself does not mean that the material is ultimately admissible or discoverable.

Why Confidentiality and Privilege Matter

Confidentiality and privileged communications are essential parts of the architecture of evidence law.

The judicial system seeks relevant evidence because accurate adjudication depends upon reliable information. Yet unrestricted access to every communication would undermine relationships that the law considers important.

People must sometimes be able to speak candidly with lawyers, therapists, physicians, spouses, mediators, and other protected professionals or participants.

The law therefore creates different forms of protection.

Some are professional duties of confidentiality.

Some are evidentiary privileges.

Some are statutory protections.

Some are constitutional.

Some arise from procedural rules.

Understanding which protection applies is more important than simply describing information as “confidential.”

The central lesson is therefore:

Confidentiality and privilege overlap, but they answer different legal questions.

Confidentiality asks whether information is subject to an obligation or expectation of restricted disclosure.

Privilege asks whether the law gives a person a right to resist compelled disclosure of qualifying information in a legal proceeding.

That distinction becomes indispensable when analyzing discovery, subpoenas, depositions, professional obligations, and trial evidence.

Key Takeaways

Confidentiality and privilege are related but distinct legal concepts.

Confidentiality generally concerns an obligation or expectation that information will remain private.

Evidentiary privilege is a legal protection against compelled disclosure of qualifying communications or information.

A communication may be confidential without being privileged.

Confidentiality is often an important element of a privilege, particularly attorney-client privilege.

Attorney-client privilege protects qualifying confidential communications concerning legal advice or legal services.

An attorney’s professional duty of confidentiality is broader than the evidentiary attorney-client privilege and can apply outside litigation.

Privilege generally protects communications rather than independently existing underlying facts.

The presence of an unnecessary third party can undermine confidentiality and privilege.

Digital communications can be privileged, but careless forwarding, copying, or sharing can create waiver problems.

Medical confidentiality and physician-patient privilege are not identical, and physician-patient privilege is primarily governed by state law.

Work-product protection is distinct from attorney-client privilege.

Protective orders and confidentiality agreements are not necessarily evidentiary privileges.

Privileges may be waived, although specific rules such as Federal Rule of Evidence 502 protect against certain forms of inadvertent waiver.

The applicable privilege always depends on the jurisdiction, relationship, purpose of the communication, confidentiality, exceptions, and possible waiver.

Frequently Asked Questions

What is the difference between confidentiality and privilege?

Confidentiality generally concerns keeping information private or restricting its disclosure. Privilege is a specific legal protection that can allow a person to resist compelled disclosure of qualifying information in a legal proceeding.

Is every confidential communication privileged?

No. A communication can be private and confidential without falling within any recognized evidentiary privilege.

What is a privileged communication?

A privileged communication is a communication protected by a recognized legal privilege from compelled disclosure, subject to applicable exceptions and waiver.

Does attorney-client confidentiality equal attorney-client privilege?

No. Attorney-client confidentiality is a broader professional duty. Attorney-client privilege is an evidentiary doctrine that protects qualifying communications from compelled disclosure.

Does attorney-client privilege protect facts?

Generally, no. It protects qualifying communications rather than facts that independently exist and can be obtained from another source.

Can a third party destroy attorney-client privilege?

An unnecessary third party’s presence or receipt of a communication can undermine confidentiality and potentially destroy or waive privilege. But third parties who are necessary to facilitate legal advice may sometimes participate without defeating protection.

Does labeling a document “privileged and confidential” make it privileged?

No. Courts examine the substance, purpose, participants, and circumstances of the communication. A label alone does not create privilege.

Can confidential information be disclosed in court?

Potentially. Confidentiality by itself does not necessarily prevent compelled disclosure. Whether disclosure can be compelled depends on the applicable privilege, statute, protective order, constitutional protection, or other legal doctrine.

Does HIPAA create an evidentiary privilege?

HIPAA primarily regulates protected health information and does not create a universal evidentiary physician-patient privilege. Physician-patient privilege is primarily a matter of state law.

Can privileged communications be accidentally disclosed?

Yes. Accidental disclosure can occur, particularly in electronic discovery. Under Federal Rule of Evidence 502, certain inadvertent disclosures do not result in waiver when specified requirements are satisfied.

Does privilege protect an entire lawyer’s file?

No. Different materials in a lawyer’s file may receive different forms of protection. Attorney-client communications, work product, factual materials, and public documents must be analyzed separately.

Can privilege survive the end of a relationship?

It can. Certain privileges, including attorney-client privilege, can continue after representation ends. The precise effect depends on the particular doctrine and applicable law.

Why does the law protect privileged communications?

The law recognizes that some relationships depend upon candid communication. Protecting those communications can encourage people to seek advice, disclose relevant information, and participate honestly in relationships that serve important legal or social purposes.
