Privileges in Evidence

Privileges in Evidence

Privileges are rules of evidence that protect certain communications, relationships, or information from compelled disclosure in legal proceedings. They represent an important exception to the general principle that courts should have access to relevant evidence.

A privileged communication may be relevant, reliable, and otherwise admissible, yet still be protected from disclosure because the law has determined that preserving a particular relationship or constitutional interest is more important than obtaining that evidence.

Privileges therefore involve a deliberate limitation on the truth-finding function of the judicial system. The law recognizes that some relationships work properly only when people can communicate with a reasonable expectation that their communications will remain protected. If every conversation between a client and lawyer, patient and psychotherapist, or spouses could later be compelled in court, people might withhold information necessary for those relationships to function effectively.

The concept is broader than confidentiality. A communication may be confidential in an ordinary sense without being legally privileged. Privilege is a legal protection against compelled disclosure.

In the federal system, privileges are principally governed by Federal Rule of Evidence 501. Unlike many other areas of evidence, the Federal Rules of Evidence do not contain a comprehensive catalog of every recognized privilege. Instead, federal privilege law generally develops through common-law principles, constitutional provisions, federal statutes, and judicial decisions. In federal civil cases involving claims or defenses governed by state law, Rule 501 generally directs federal courts to apply the privilege law of the relevant state.

What Is an Evidentiary Privilege?

An evidentiary privilege is a legal protection that allows a person, relationship, or institution to resist compelled disclosure of certain protected information in a legal proceeding.

The protection can arise in several ways.

A privilege may be based on:

• the United States Constitution;
• federal statutes;
• federal common law;
• state statutes;
• state common law;
• or judicially recognized doctrines.

The precise scope depends on the privilege involved and the jurisdiction in which the issue arises.

Cornell’s Legal Information Institute describes privilege in evidence as a rule protecting certain communications from disclosure in legal proceedings. Privileges are grounded in public policy judgments that the benefits of protecting particular relationships can outweigh the loss of potentially relevant evidence.

The central idea can be expressed simply:

Relevant evidence is not necessarily discoverable or admissible if a valid privilege protects it.

Why Does the Law Recognize Privileges?

The principal justification for privileges is not that the protected information is unreliable.

Quite often, privileged communications may be extremely reliable and highly relevant.

The reason for protection is instead that the legal system considers another interest sufficiently important to justify restricting access to the information.

For example, a person seeking legal advice may need to tell a lawyer facts that would be embarrassing, damaging, or otherwise sensitive. If the client believed that every communication could later be compelled by an opposing party, the client might withhold information from the lawyer.

That could impair the lawyer’s ability to provide competent legal advice.

Similarly, a patient may be less willing to communicate honestly with a psychotherapist if the patient knows that every disclosure could automatically become evidence in later litigation.

The law therefore accepts a certain evidentiary cost in exchange for encouraging protected communications.

Privilege Is an Exception to Ordinary Evidence Principles

The ordinary structure of evidence favors the presentation of relevant information.

A fact that helps prove or disprove a material issue will ordinarily be considered potentially useful to the factfinder.

Privilege operates differently.

A court may conclude:

“This information is relevant, but the law protects it from compelled disclosure.”

This is why privileges are often described as exceptions to the truth-seeking function of litigation.

The existence of a privilege does not mean that the information is false, irrelevant, or unreliable. It means that the legal system has decided that the information should not be compelled or used in the ordinary manner despite its potential evidentiary value.

Because privileges limit the availability of evidence, courts commonly approach privilege claims carefully and require the party asserting the privilege to establish its applicability.

Federal Rule of Evidence 501

Federal Rule of Evidence 501 is the central federal rule governing privileges.

Unlike rules concerning relevance, hearsay, authentication, or character evidence, Rule 501 does not provide a detailed list of every privilege.

Instead, it provides that federal privilege questions generally are governed by common-law principles as interpreted by federal courts in light of reason and experience, subject to the Constitution, federal statutes, and rules prescribed by the Supreme Court.

There is also an important state-law provision.

When a federal civil case involves an element of a claim or defense for which state law supplies the rule of decision, Rule 501 generally requires the federal court to apply the privilege law determined by that state.

This means that the same communication can potentially receive different privilege treatment depending on the jurisdiction and the legal basis of the proceeding.

Privileges Are Not the Same as Confidentiality

Confidentiality and privilege are closely related but are not identical concepts.

A communication can be confidential in an ordinary sense without being legally privileged.

For example, two friends may have a private conversation. They may reasonably expect that neither will repeat it publicly. But that expectation does not automatically create an evidentiary privilege.

A privilege requires a recognized legal doctrine protecting the communication or information from compelled disclosure.

The distinction becomes especially important in professional relationships.

Attorney-client confidentiality is broader in some respects than the attorney-client evidentiary privilege. A lawyer’s professional duty of confidentiality can apply outside litigation and outside formal evidentiary proceedings, whereas evidentiary privilege specifically concerns legal protection against compelled disclosure in contexts governed by the privilege doctrine.

Privilege Versus Privacy

Privilege should also be distinguished from privacy.

Privacy generally concerns a person’s interest in controlling access to personal information or activities.

Privilege is a legal rule concerning compelled disclosure or use of information in legal proceedings.

A person can have a legitimate expectation of privacy without possessing an evidentiary privilege.

For example, private medical information may receive protection under privacy statutes, professional duties, or other legal doctrines. Whether a particular medical communication is privileged in litigation is a separate question.

This distinction is particularly important because federal privacy law and evidentiary privilege do not operate identically.

Attorney-Client Privilege

The attorney-client privilege is one of the best-known evidentiary privileges.

It generally protects confidential communications between a lawyer and client made for the purpose of obtaining or providing legal advice or legal services.

The privilege encourages clients to communicate candidly with their lawyers.

The protection can extend to different forms of communication, including oral conversations, letters, emails, text messages, and other communications when the requirements of the privilege are satisfied.

The privilege generally belongs to the client rather than the lawyer.

The client may assert the privilege when a party seeks protected communications in discovery, at a deposition, through a subpoena, or in another legal proceeding.

What Must Be Present?

Although formulations vary somewhat by jurisdiction, attorney-client privilege generally requires several basic elements.

There must be an attorney-client relationship or a communication made in circumstances in which legal representation is being sought.

The communication must generally be confidential.

The communication must concern legal advice or services rather than merely ordinary business matters.

And the communication must not fall within an applicable exception.

The privilege therefore does not protect everything a client tells a lawyer.

A lawyer may wear several roles. A client may communicate with a lawyer about business strategy, personal matters, administrative tasks, or purely factual matters. The question is whether the particular communication falls within the legal-advice relationship protected by the privilege.

Attorney-Client Privilege Is Not a General Secrecy Rule

A common misunderstanding is that everything transmitted between a lawyer and client is automatically privileged.

That is incorrect.

The privilege protects qualifying communications, not every piece of information known by the lawyer.

For example, the underlying facts may exist independently of the communication.

Suppose a client tells a lawyer:

“I was present at the warehouse at 9:00 p.m.”

The communication may be privileged if it qualifies as a confidential communication for legal advice.

But the underlying fact that the client was present at the warehouse is not transformed into a privileged fact merely because the client told the lawyer about it.

An opposing party may be able to obtain the underlying facts from another source even though the client’s communication to the lawyer is protected.

The Crime-Fraud Exception

Attorney-client privilege does not ordinarily protect communications made for the purpose of obtaining legal assistance to further a crime or fraud.

This is commonly known as the crime-fraud exception.

The exception reflects a fundamental distinction between seeking legal advice about past conduct and using a lawyer’s services as part of an ongoing or planned unlawful scheme.

The mere fact that a lawyer represents a person accused of wrongdoing does not destroy the privilege.

A client can confidentially tell a lawyer about past conduct and seek legal advice concerning it.

The critical question is whether the communication falls within the circumstances covered by the crime-fraud exception.

Waiver of Attorney-Client Privilege

Privilege can be lost through waiver.

One of the most common ways waiver occurs is disclosure of a privileged communication to a third party whose presence is inconsistent with confidentiality.

For example, if a client deliberately forwards a privileged legal email to an unrelated third party, the disclosure may undermine the privilege.

Federal Rule of Evidence 502 addresses waiver and related issues involving attorney-client privilege and work product. Under specified circumstances, an inadvertent disclosure does not necessarily produce a complete waiver, particularly when reasonable precautions were taken and reasonable corrective steps followed the disclosure.

Privilege questions involving waiver are highly fact-specific.

Attorney-Client Privilege and Corporate Clients

Attorney-client privilege also applies in appropriate circumstances to communications involving organizations.

A corporation can obtain legal advice through its lawyers, and communications made for the purpose of obtaining or providing that advice may be privileged.

But corporate privilege creates difficult questions about who is acting for the client and whether a particular communication concerns legal advice.

Employees may communicate with corporate counsel. Outside consultants may participate. Business executives may be involved in the same communication.

The presence of multiple participants does not automatically destroy privilege, but the circumstances must be examined carefully.

The key issue remains whether the communication falls within the protected attorney-client relationship and was made for the purpose of obtaining or providing legal advice.

Work Product Protection

Attorney work product is closely related to privilege but is analytically distinct from the attorney-client privilege.

The work-product doctrine protects certain documents and tangible materials prepared in anticipation of litigation or for trial.

It can cover materials prepared by attorneys as well as materials prepared by certain representatives of a party.

Federal Rule of Civil Procedure 26(b)(3) provides the principal federal protection.

Work product is generally divided into ordinary work product and opinion work product.

Ordinary work product may include factual materials prepared in anticipation of litigation.

Opinion work product includes an attorney’s mental impressions, conclusions, opinions, legal theories, and litigation strategy.

Opinion work product receives particularly strong protection.

Work product is therefore not simply another name for attorney-client privilege.

Attorney-client privilege primarily protects qualifying confidential communications between attorney and client.

Work-product protection primarily protects qualifying litigation-preparation materials.

The two doctrines can overlap, but they serve different functions.

Spousal Privilege

Spousal privilege, sometimes called marital privilege, encompasses more than one doctrine.

Two major forms are commonly distinguished:

spousal testimonial privilege, and

marital communications privilege.

Although the details vary among jurisdictions, understanding the distinction is essential.

Spousal Testimonial Privilege

Spousal testimonial privilege generally concerns whether one spouse can be compelled to testify against the other in certain criminal proceedings.

Its traditional rationale is the protection of marital harmony and the marital relationship.

The precise holder of the privilege and its scope vary by jurisdiction.

In federal criminal law, the Supreme Court’s decision in Trammel v. United States is particularly important because it addressed the federal marital privilege and the authority of the witness spouse.

The privilege is generally associated with testimony by one spouse against the other rather than simply with confidential communications.

Marital Communications Privilege

Marital communications privilege protects qualifying confidential communications between spouses.

Unlike testimonial privilege, it focuses on the communication itself.

A communication must generally have been intended to remain confidential.

For example, a private conversation between spouses may qualify, while a statement made openly in front of unrelated third parties ordinarily will not.

Cornell distinguishes these two forms of spousal privilege and notes that their scope and operation can differ substantially.

Privilege and Divorce

The fact that spouses are involved in litigation against each other creates particularly important questions.

Spousal privileges generally do not operate in the same way when the spouses are themselves opposing parties in litigation such as divorce proceedings.

State law becomes especially important in this area because privilege doctrines involving spouses can differ significantly among jurisdictions.

The existence of a marriage therefore does not create a universal rule that every communication between spouses is protected in every legal proceeding.

Physician-Patient Privilege

Physician-patient privilege protects certain confidential communications between a physician and patient.

Its purpose is to encourage patients to provide complete information necessary for medical treatment without fear that the information will later be compelled in litigation.

But physician-patient privilege illustrates why privilege law must always be analyzed jurisdiction by jurisdiction.

There is no general physician-patient privilege under the Federal Rules of Evidence comparable to the federal psychotherapist-patient privilege. Physician-patient privilege is primarily created by state statutes and therefore varies significantly among states.

This distinction is extremely important.

A person cannot assume that medical information is automatically privileged merely because it was communicated to a doctor.

The applicable state law, the nature of the proceeding, the relationship between the patient and provider, and any statutory exceptions may determine whether the information is protected.

Physician-Patient Privilege Versus Medical Privacy

Medical privacy and physician-patient privilege are not identical.

Medical privacy may be protected by statutes, regulations, professional obligations, contractual duties, and other legal mechanisms.

Privilege concerns whether information can be compelled or used in a legal proceeding.

For example, HIPAA protects certain health information in specified circumstances, but HIPAA should not simply be treated as a universal evidentiary privilege.

The existence of medical privacy protections therefore does not automatically answer an evidentiary privilege question.

Psychotherapist-Patient Privilege

The federal courts recognize a psychotherapist-patient privilege.

The Supreme Court addressed the federal privilege in Jaffee v. Redmond.

The privilege protects confidential communications between a patient and a licensed psychotherapist or certain other recognized mental-health professionals when the requirements of the privilege are satisfied.

The underlying rationale is that effective mental-health treatment depends on the patient’s willingness to communicate candidly.

The privilege is therefore designed to protect the therapeutic relationship rather than merely to protect medical records.

Communications Versus Underlying Facts

One of the most important distinctions in privilege law is the difference between a communication and the underlying fact.

Privilege often protects the communication itself, not the existence of the underlying event.

Suppose a client tells a lawyer:

“I signed the contract on Monday.”

The communication may be privileged.

But the fact that the contract was signed on Monday is not necessarily privileged merely because it was communicated to the lawyer.

The opposing party may seek evidence of the signing from the contract, witnesses, electronic records, or other sources.

This principle prevents privilege from becoming a mechanism for hiding otherwise discoverable facts merely by communicating those facts to a protected professional.

Privilege and Discovery

Privilege plays an especially important role during discovery.

Discovery is designed to allow parties to obtain relevant information before trial. But discovery is not unlimited.

Privileged material may be protected from compelled disclosure even when it is relevant to the dispute.

A party responding to a discovery request may therefore assert privilege rather than produce a protected communication or document.

The party may be required to identify the privilege being asserted and provide enough information to allow the opposing party and court to evaluate the claim without revealing the privileged substance itself.

In federal civil litigation, privilege intersects with the broader discovery rules governing attorney-client communications and work product.

Privilege Logs

When privileged documents are withheld during discovery, parties may use a privilege log.

A privilege log typically identifies withheld materials sufficiently to permit the opposing party to evaluate the claim without disclosing the protected content itself.

Depending on the governing rules and court orders, the log may identify information such as:

• the date of the document;
• the author;
• the recipients;
• the general type of document;
• the privilege asserted; and
• a general description of its subject matter.

The purpose is to permit meaningful evaluation of the privilege claim without forcing disclosure of the very information the privilege is designed to protect.

The precise requirements vary by jurisdiction and court.

Privilege and Third Parties

Confidentiality is central to many privileges.

A communication that occurs in the presence of an unnecessary third party may lose its privileged character because the circumstances demonstrate that confidentiality was not maintained.

But the presence of a third person does not automatically destroy every privilege.

For example, an interpreter may be necessary to facilitate communication between attorney and client.

Similarly, certain representatives or agents may participate in a privileged relationship when their involvement is necessary to provide or receive the protected service.

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

Waiver

Waiver occurs when the holder of a privilege intentionally or, in some circumstances, inadvertently relinquishes the protection.

The rules governing waiver differ among privileges.

Common circumstances that can create waiver include:

• voluntary disclosure of the protected communication;
• disclosure to an unnecessary third party;
• placing privileged communications affirmatively at issue;
• failing to maintain confidentiality;
• using protected information in a manner inconsistent with the privilege.

Waiver can sometimes be limited rather than complete.

Federal Rule of Evidence 502 was designed in part to address the consequences of certain disclosures of attorney-client privileged and work-product material.

The precise effect of waiver depends on the governing rule, privilege, circumstances, and jurisdiction.

Privilege and Inadvertent Disclosure

Modern litigation creates a particular risk of accidental disclosure.

Electronic discovery may involve millions of documents, multiple review teams, automated search systems, and rapid production schedules.

A privileged email can therefore accidentally appear in a production set.

The existence of an accidental disclosure does not necessarily mean that all privilege protection has disappeared.

Federal Rule of Evidence 502 establishes specific rules governing certain disclosures, including circumstances in which an inadvertent disclosure does not operate as a waiver.

Courts also frequently consider the precautions taken before disclosure and the steps taken after the error is discovered.

Who Holds the Privilege?

The identity of the privilege holder matters.

Different privileges belong to different people.

For example, attorney-client privilege generally belongs to the client.

Other privileges may belong to the witness, patient, spouse, or another protected person.

Determining the holder matters because the holder ordinarily has the authority to assert or waive the privilege.

A lawyer may have a professional obligation not to disclose information, but that does not necessarily mean that the lawyer personally owns the client’s evidentiary privilege.

The distinction becomes particularly important when a dispute arises over waiver.

Privilege and Former Relationships

The end of a relationship does not always terminate a privilege.

For example, attorney-client privilege can continue to protect qualifying communications after representation ends.

Similarly, certain confidential marital communications may remain protected after a marriage ends, depending on the applicable jurisdiction and doctrine.

By contrast, some privileges depend upon an existing relationship at the time disclosure is sought.

The legal effect of termination therefore depends on the particular privilege.

Privilege and Death

Privilege can also survive the death of the person who originally held it.

The Supreme Court’s decision in Swidler & Berlin v. United States recognized the continuing force of attorney-client privilege after the client’s death in the circumstances presented there.

The Court emphasized that the privilege serves purposes broader than simply protecting a living client’s immediate interests. The assurance of confidentiality can be necessary for people to communicate candidly with counsel in the first place.

Whether another privilege survives death depends on the particular doctrine and applicable law.

Constitutional Privileges

Not all privileges are ordinary evidentiary privileges created by common law or statute.

Some protections arise directly from the Constitution.

The most important example is the Fifth Amendment privilege against self-incrimination.

The Fifth Amendment provides that a person may not be compelled in a criminal case to be a witness against himself.

This protection differs fundamentally from relationship-based privileges.

Attorney-client privilege protects qualifying communications within a particular professional relationship.

The privilege against self-incrimination protects an individual against compelled testimonial self-incrimination in circumstances covered by the Fifth Amendment.

The constitutional privilege therefore has its own rules, limitations, exceptions, and jurisprudence.

Privilege Against Self-Incrimination

The privilege against self-incrimination is particularly important in criminal proceedings.

A person may invoke the privilege when compelled testimony could be incriminating within the meaning of the Fifth Amendment.

The privilege is not simply a general right to refuse to answer every difficult question.

Its scope depends on whether the compelled response would be testimonial, incriminating, and compelled in circumstances to which the Fifth Amendment applies.

The doctrine also differs between testimony and physical evidence.

For example, the constitutional privilege generally protects against compelled testimonial communication, not every form of compelled evidence.

The constitutional nature of this protection makes it distinct from ordinary relationship-based privileges.

Governmental and Institutional Privileges

The law also recognizes certain privileges involving governmental interests.

Examples can include protections involving government deliberations, national security, certain investigative materials, or other governmental functions.

These doctrines can arise from constitutional principles, statutes, common law, or specialized rules.

Governmental privileges are particularly complex because they require courts to balance individual access to evidence against institutional interests such as public safety, effective administration, and protection of sensitive governmental information.

They should therefore be analyzed separately from ordinary personal privileges.

Privilege Is Different from the Work-Product Doctrine

Because attorney-client privilege and work product frequently appear together in litigation, they are sometimes treated as interchangeable.

They are not.

Attorney-client privilege protects qualifying confidential communications between lawyer and client.

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

A document can therefore be protected as work product even though it does not constitute an attorney-client communication.

For example, an attorney’s internal litigation strategy memorandum may contain no communication from the client at all. It may nevertheless receive work-product protection because it reflects preparation for litigation and the attorney’s mental impressions or legal theories.

Privilege Is Different from the Hearsay Rule

Privilege and hearsay address different questions.

Hearsay generally concerns an out-of-court statement offered for its truth.

Privilege concerns whether protected information may be compelled or disclosed at all.

A communication can therefore be:

• non-hearsay but privileged;
• hearsay but not privileged;
• both hearsay and privileged;
• or neither.

For example, a confidential attorney-client communication may be privileged even if it is not being offered to prove the truth of anything.

The hearsay analysis and privilege analysis must therefore be conducted separately.

Privilege Is Different from Relevance

Privilege is also different from relevance.

Relevant evidence tends to make a material fact more or less probable.

Privilege can protect evidence that is highly relevant.

For example, suppose a party’s confidential communication to counsel directly addresses a disputed issue. The communication may be extremely probative.

If it is protected by attorney-client privilege and no exception or waiver applies, its relevance does not eliminate the privilege.

This demonstrates the fundamental nature of privilege: it can exclude evidence precisely because it is relevant.

Privilege and the Factfinder

When a valid privilege applies, the protected information generally is not presented to the factfinder in the ordinary course.

This can create difficult consequences.

The jury may never hear evidence that would potentially affect its decision.

But that result is intentional.

The legal system accepts the loss of certain evidence because it believes that protecting the underlying relationship or constitutional interest produces a greater systemic benefit.

Privilege is therefore a policy choice embedded within the law of evidence.

The Burden of Establishing Privilege

The party asserting privilege generally bears the burden of establishing that the privilege applies.

This commonly requires showing:

1. that a recognized privilege exists;
2. that the relevant relationship or circumstances fall within the privilege;
3. that the communication or material satisfies the substantive requirements;
4. that confidentiality was maintained when confidentiality is required;
5. and that no waiver or exception defeats the protection.

The precise burden and procedure can vary depending on the privilege and jurisdiction.

Courts may examine documents in camera when necessary to determine whether a privilege applies without requiring the disputed material to be publicly disclosed.

In Camera Review

An in camera review occurs when a judge examines disputed material privately rather than requiring the parties or public to view it.

This procedure can be particularly useful in privilege disputes.

Suppose a party claims that an email is attorney-client privileged while the opposing party argues that it is an ordinary business communication.

The judge may examine the email privately to determine whether the privilege applies.

In camera review does not itself establish privilege. It is a procedural mechanism that can assist the court in resolving the privilege dispute.

Common Mistakes in Privilege Analysis

One of the most common mistakes is assuming that every confidential communication is privileged.

Confidentiality is important, but confidentiality alone does not create a privilege.

Another mistake is assuming that privilege protects facts.

Usually, privilege protects qualifying communications or materials rather than facts that independently exist.

A third mistake is assuming that hiring a lawyer makes everything related to the lawyer privileged.

It does not.

A fourth mistake is assuming that privilege rules are identical throughout the United States.

They are not.

A fifth mistake is treating privacy statutes such as HIPAA as synonymous with evidentiary privilege.

They serve different legal functions.

Finally, parties sometimes assume that once privilege is established, it can never be waived. Privilege can be waived under appropriate circumstances, although some federal rules provide protection against certain forms of inadvertent waiver.

A Practical Framework for Analyzing a Privilege Claim

When a party asserts privilege, a structured analysis can help.

Identify the Information

Determine exactly what is being withheld.

Is it a conversation, email, document, recording, photograph, report, memorandum, testimony, or other material?

Identify the Claimed Privilege

Determine which doctrine is being invoked.

For example:

• attorney-client privilege;
• marital communications privilege;
• spousal testimonial privilege;
• psychotherapist-patient privilege;
• physician-patient privilege under applicable state law;
• Fifth Amendment privilege against self-incrimination;
• work-product protection;
• or another recognized privilege.

Identify the Governing Law

Determine whether the proceeding is in federal or state court and whether federal or state law governs the privilege question.

Rule 501 makes this especially important in federal civil cases involving state-law claims or defenses.

Identify the Relationship

Ask whether the parties have the relationship required by the claimed privilege.

A lawyer-client relationship, psychotherapist-patient relationship, or marital relationship may be essential to the analysis.

Determine Whether the Communication Was Confidential

If confidentiality is an element of the privilege, determine whether the circumstances demonstrate an intention that the communication remain confidential.

Determine the Purpose of the Communication

The purpose matters greatly.

For attorney-client privilege, a communication made to obtain legal advice is fundamentally different from a communication concerning ordinary business administration.

Examine Third-Party Participation

Determine whether anyone outside the protected relationship was present or received the communication.

Then determine whether that person’s participation was consistent with maintaining the privilege.

Check for Exceptions

Even when the basic elements are satisfied, an exception may apply.

Crime-fraud principles, litigation-related exceptions, statutory exceptions, and other doctrines can limit protection.

Check for Waiver

Determine whether the holder voluntarily disclosed the material or otherwise acted inconsistently with maintaining the privilege.

Consider the Scope of Protection

Finally, determine exactly what is protected.

A privilege may protect the communication without protecting the underlying facts.

Why Privileges Matter to the Evidence System

Privileges reveal that evidence law is not concerned exclusively with obtaining every piece of available information.

The legal system also protects relationships and social interests that it considers important enough to justify limiting access to evidence.

This creates a fundamental tension.

On one side is the interest in discovering the truth.

On the other is the interest in encouraging confidential communications, protecting constitutional rights, preserving important relationships, and maintaining certain institutional functions.

Privileges represent the point at which the law deliberately chooses not to maximize the amount of evidence available to the court.

That choice can sometimes make litigation more difficult. But the legal system accepts that cost because certain relationships would function differently if every communication could later be compelled.

Key Takeaways

Privileges protect certain communications, information, relationships, or interests from compelled disclosure.

Privilege is different from confidentiality, privacy, relevance, hearsay, and work-product protection.

Federal Rule of Evidence 501 is the principal federal rule governing privileges, but it does not provide a comprehensive statutory list of every privilege.

Federal privilege law generally develops through common law, constitutional provisions, federal statutes, and judicial decisions.

In federal civil cases involving claims or defenses governed by state law, state privilege law may control under Rule 501.

Attorney-client privilege protects qualifying confidential communications made for the purpose of obtaining or providing legal advice.

The attorney-client privilege belongs generally to the client and can be waived.

The crime-fraud exception can prevent attorney-client protection for qualifying communications used to further a crime or fraud.

Work-product protection is distinct from attorney-client privilege and generally concerns materials prepared in anticipation of litigation or for trial.

Spousal privilege includes distinct doctrines concerning confidential marital communications and testimony by one spouse against another.

Physician-patient privilege is primarily a matter of state law in the United States, while federal law recognizes a psychotherapist-patient privilege.

The Fifth Amendment privilege against self-incrimination is constitutional and fundamentally different from relationship-based evidentiary privileges.

Privilege generally protects qualifying communications or materials rather than the underlying facts themselves.

The party asserting privilege generally must establish that the privilege applies.

Privilege disputes may arise during discovery, depositions, subpoenas, and trial.

Frequently Asked Questions

What is privilege in evidence?

Privilege is a legal protection that prevents certain communications, information, or testimony from being compelled or disclosed in legal proceedings when the requirements of the applicable privilege are satisfied.

What is the purpose of evidentiary privilege?

The primary purpose is to protect relationships or interests that the legal system considers sufficiently important to justify restricting access to otherwise relevant evidence.

Is every confidential communication privileged?

No. Confidentiality is often an element of a privilege, but confidentiality alone does not create a legal privilege.

What is the most common evidentiary privilege?

Attorney-client privilege is one of the most widely recognized privileges and is particularly important in both litigation and legal practice.

Does attorney-client privilege protect everything a lawyer knows about a client?

No. It generally protects qualifying confidential communications made for the purpose of obtaining or providing legal advice, rather than every fact or piece of information known by the lawyer.

Who owns attorney-client privilege?

The privilege generally belongs to the client, who ordinarily has the authority to assert or waive it.

Can attorney-client privilege be waived?

Yes. Disclosure of protected communications or other conduct inconsistent with confidentiality can result in waiver, although federal law provides specific protections concerning certain inadvertent disclosures.

Is work product the same as attorney-client privilege?

No. Attorney-client privilege protects qualifying confidential communications between lawyer and client. Work-product protection generally protects materials prepared in anticipation of litigation or for trial.

Is there a federal doctor-patient privilege?

There is no general physician-patient privilege under the Federal Rules of Evidence. Physician-patient privilege is primarily established by state law. Federal law does recognize a psychotherapist-patient privilege.

Are communications between spouses always privileged?

No. Different spousal privileges apply in different circumstances, and their scope varies by jurisdiction. The distinction between spousal testimonial privilege and marital communications privilege is particularly important.

Does privilege protect facts?

Usually, privilege protects qualifying communications or materials rather than independently existing facts. A party may often be required to disclose a fact even if the party previously communicated that fact to a lawyer.

Can privileged information be discovered?

Generally, properly protected privileged material is not subject to ordinary compelled disclosure. However, whether a particular item is privileged depends on the applicable doctrine, and exceptions or waiver may eliminate protection.

Does privilege apply equally in every state?

No. Privilege law varies considerably among states. Federal Rule of Evidence 501 also makes the governing law particularly important in federal civil cases involving state-law claims or defenses.

Why does the law protect evidence that may be relevant?

The law recognizes that unrestricted disclosure could undermine relationships and constitutional interests that society considers important. Privilege therefore reflects a policy decision to sacrifice some potentially useful evidence in order to preserve those interests.

Is the Fifth Amendment privilege the same as attorney-client privilege?

No. The Fifth Amendment privilege against self-incrimination is a constitutional protection against certain forms of compelled self-incriminating testimony. Attorney-client privilege is a relationship-based protection for qualifying communications between lawyer and client.
