Attorney-Client Privilege
Attorney-client privilege is a legal protection that generally prevents compelled disclosure of confidential communications between a lawyer and client made for the purpose of seeking or providing legal advice.
The privilege is one of the oldest recognized protections in the law of evidence. Its central purpose is to encourage clients to communicate fully and honestly with their lawyers so that lawyers can provide informed legal advice. As the Supreme Court explained in Upjohn Co. v. United States, the privilege is intended to encourage “full and frank communication” between attorneys and their clients and thereby promote broader interests in compliance with law and the administration of justice.
In federal litigation, attorney-client privilege is particularly important during discovery. A document, email, text message, or conversation may be highly relevant to a lawsuit but nevertheless protected from compelled disclosure if it falls within the privilege.
The Cornell Law School Legal Information Institute’s explanation of attorney-client privilege describes the doctrine as protecting confidential communications between attorney and client concerning the client’s request for or receipt of legal advice.
But the privilege has limits. It does not protect every communication with a lawyer, every document in a lawyer’s possession, or every fact known by a client and lawyer. The communication generally must be confidential and connected to the provision or receipt of legal advice. The privilege can also be waived, and numerous exceptions and special rules affect its application.
Understanding those boundaries is essential to understanding modern civil discovery.
What Is Attorney-Client Privilege?
Attorney-client privilege is an evidentiary privilege protecting qualifying confidential communications between an attorney and client.
The privilege generally permits the client to refuse to disclose protected communications and to prevent others from disclosing them.
For example, suppose a business owner sends an email to the company’s lawyer stating:
We received a demand letter. What legal obligations do we have, and what should we do next?
If the communication is confidential and made for the purpose of obtaining legal advice, it may fall within the attorney-client privilege.
Similarly, a lawyer’s confidential response providing legal advice may also be protected.
The important point is that the privilege generally protects the communication, not simply the underlying subject matter.
Why Does the Privilege Exist?
The privilege rests on a policy judgment.
Effective legal representation requires accurate information.
A client who fears that every confidential communication with a lawyer could later be compelled in court might withhold important facts.
That could prevent the lawyer from:
- identifying legal problems;
- evaluating risks;
- advising the client about compliance;
- assessing litigation exposure;
- negotiating effectively;
- or developing an appropriate legal strategy.
The privilege therefore encourages clients to communicate candidly.
It is not primarily designed to protect clients from embarrassment or unfavorable facts.
Its purpose is to facilitate the professional relationship between lawyer and client and the provision of legal advice.
The Privilege Is a Rule of Evidence
Attorney-client privilege is fundamentally a rule concerning protected communications and compelled disclosure.
Federal Rule of Evidence 501 provides the general federal framework for privileges.
Unlike many of the Federal Rules of Evidence, the federal rules do not provide a comprehensive statutory definition of attorney-client privilege.
Instead, federal courts generally apply the principles of common law as developed by the federal courts, subject to Rule 501 and applicable governing law.
The Cornell text of Federal Rule of Evidence 501 provides the starting point for understanding federal privilege law.
The Basic Elements of Attorney-Client Privilege
Although formulations vary somewhat among jurisdictions, a typical attorney-client privilege analysis asks whether:
- there is an attorney-client relationship;
- the communication was between protected participants;
- the communication was intended to be confidential;
- the communication concerned legal advice or services;
- the privilege has not been waived;
- and no applicable exception defeats the protection.
Each element matters.
A communication can involve a lawyer and a client and still fail to qualify as privileged.
An Attorney-Client Relationship Must Exist
The privilege ordinarily requires an attorney-client relationship.
A person cannot simply label a conversation “privileged” and thereby create the privilege.
The relationship must actually exist under the applicable law.
This creates practical problems in situations such as:
- initial consultations;
- prospective clients;
- communications with a lawyer before formal engagement;
- communications with former clients;
- and communications with lawyers serving multiple roles.
The precise rules concerning prospective clients and other preliminary communications may vary by jurisdiction.
Who Is the Client?
The identity of the client is sometimes obvious.
An individual who hires a lawyer for personal legal advice is ordinarily the client.
But organizational clients create more complicated questions.
A corporation is a legal entity and cannot literally speak to its lawyer itself.
Its communications occur through:
- officers;
- directors;
- employees;
- agents;
- or other representatives.
The question then becomes whether a particular communication between an organizational representative and corporate counsel falls within the corporation’s attorney-client privilege.
Corporate Attorney-Client Privilege
The Supreme Court addressed the scope of corporate attorney-client privilege in Upjohn Co. v. United States, 449 U.S. 383 (1981).
The case involved communications between corporate employees and company attorneys during an internal investigation.
The Supreme Court rejected a narrow approach that would have limited corporate privilege primarily to communications from a small group of corporate decision-makers.
Instead, the Court recognized that employees may communicate with corporate counsel when the communications concern matters within the scope of their corporate responsibilities and are made for the purpose of obtaining legal advice for the corporation.
The decision is particularly important because corporate legal advice often depends on information gathered from employees throughout an organization.
The Corporate Client and the Individual Employee
An employee communicating with corporate counsel must understand an important distinction.
The lawyer may represent the corporation, not the individual employee.
A conversation can therefore be privileged while the privilege belongs to the corporation.
The employee may not personally control whether the corporation later waives the privilege.
Corporate counsel may also need to clarify whom the lawyer represents.
This becomes particularly important during:
- internal investigations;
- employment disputes;
- regulatory investigations;
- corporate litigation;
- mergers and acquisitions;
- and compliance investigations.
Communications Must Be Confidential
Confidentiality is central to attorney-client privilege.
A communication generally must be made with an expectation that it will remain confidential.
If a client voluntarily shares a privileged communication with an unrelated third party, that disclosure may destroy the privilege or constitute a waiver.
This does not mean that every person other than the lawyer and client destroys confidentiality.
Certain third parties may be necessary to facilitate the legal relationship.
For example, an interpreter may participate in a privileged communication without necessarily destroying the privilege.
The precise result depends on the circumstances and applicable law.
Confidentiality Does Not Mean Secrecy From Everyone
Attorney-client privilege does not require that the lawyer and client communicate in complete isolation.
A person assisting in the legal communication may sometimes be considered sufficiently connected to the attorney-client relationship.
Examples can include:
- interpreters;
- certain legal staff;
- necessary agents;
- and other persons whose participation is reasonably necessary to facilitate legal advice.
But adding unnecessary third parties creates substantial risk.
A client should not assume that copying unrelated people on an attorney-client email preserves privilege.
The Communication Must Concern Legal Advice
The attorney-client privilege protects communications made for the purpose of obtaining or providing legal advice.
This is one of its most important limitations.
A lawyer can perform many functions.
A lawyer may act as:
- legal adviser;
- negotiator;
- business consultant;
- accountant;
- administrator;
- board member;
- investigator;
- or business executive.
The privilege does not automatically cover communications merely because a lawyer is involved.
Legal Advice Versus Business Advice
Suppose a company’s general counsel sends an email recommending:
We should expand into this market because the profit margin is likely to be high.
That may be ordinary business advice rather than legal advice.
Now suppose the general counsel writes:
Based on the applicable regulatory requirements, entering this market without obtaining the required approval could expose the company to substantial penalties.
That communication is more clearly connected to legal advice.
A single communication can sometimes contain both business and legal components.
Courts may need to determine the primary or predominant purpose, or otherwise apply the jurisdiction’s particular test, to decide whether the privilege applies.
A Lawyer’s Involvement Is Not Enough
One of the most common misunderstandings is:
If a lawyer sent it, it must be privileged.
That is incorrect.
The relevant question is not simply whether an attorney participated.
The inquiry concerns the nature and purpose of the communication.
For example:
- an ordinary business report prepared by a company employee does not automatically become privileged because a lawyer receives a copy;
- an ordinary business meeting does not become privileged merely because the company’s lawyer attends;
- a public announcement drafted by counsel is not necessarily privileged;
- and a business document does not become privileged merely because it was later sent to an attorney.
Facts Are Not the Same as Communications
Attorney-client privilege generally protects qualifying communications.
It does not ordinarily allow a client to refuse to disclose an underlying fact simply because the client told the fact to a lawyer.
For example, suppose a client tells a lawyer:
I signed the contract on June 15.
The confidential communication concerning that fact may be privileged.
But the underlying historical fact—that the client signed the contract on June 15—is not necessarily transformed into a privileged fact merely because it was communicated to counsel.
This distinction is fundamental.
Privilege protects qualifying communications, not the existence of facts.
Legal Advice About Existing Facts
Suppose a company discovers that an employee altered a financial record.
The company communicates confidentially with its lawyer about what happened.
The communication seeking legal advice may be privileged.
But the underlying conduct does not become privileged simply because lawyers discussed it.
A party generally cannot shield unfavorable facts from discovery by communicating those facts to counsel.
This principle prevents attorney-client privilege from becoming a mechanism for hiding evidence.
Attorney Communications to Clients
Privilege can protect communications in both directions.
It may cover:
- a client’s confidential request for legal advice;
- the lawyer’s confidential legal advice;
- and confidential exchanges necessary to obtain or provide that advice.
For example:
Client: “Are we legally permitted to terminate this agreement?”
Attorney: “The contract’s termination clause appears to permit termination under these circumstances, but notice must be provided in the manner specified.”
Both communications may qualify if the other requirements of privilege are satisfied.
Emails and Attorney-Client Privilege
Attorney-client privilege applies to electronic communications just as it can apply to oral communications.
Potentially privileged communications may include:
- emails;
- text messages;
- secure messages;
- video conferences;
- messaging-platform communications;
- electronic documents;
- and other communications.
But the medium itself does not create the privilege.
A privileged email remains privileged because of its content, purpose, participants, and circumstances—not because it is an email.
Attorney-Client Privilege in E-Discovery
Attorney-client privilege is particularly important in e-discovery because electronically stored information can contain enormous numbers of communications involving attorneys.
A document collection may include:
- emails between employees and counsel;
- attachments;
- internal forwarding;
- legal memoranda;
- draft agreements;
- litigation communications;
- and messages involving outside counsel.
During review, parties must identify materials that may be protected by privilege.
This often requires sophisticated document-review procedures.
Privilege Logs
When a party withholds responsive information on the basis of attorney-client privilege or work-product protection, Federal Rule of Civil Procedure 26(b)(5) generally requires the party to:
- expressly make the claim; and
- describe the nature of the documents or communications withheld in a manner that enables the opposing party to assess the claim without revealing the protected information itself.
This is often accomplished through a privilege log.
A privilege log may identify:
- date;
- author;
- recipients;
- general subject;
- document type;
- and privilege asserted.
The goal is to permit the opposing party to evaluate whether the privilege claim appears legitimate without forcing disclosure of the protected substance.
Privilege and Attachments
Attachments can create complicated privilege questions.
An email between a client and lawyer may be privileged, but an attachment to that email is not necessarily privileged.
For example, a client might send a lawyer:
Please advise whether this contract creates a legal problem.
The email requesting advice may be privileged.
The underlying contract may not be privileged merely because it was attached to the privileged email.
The distinction between the communication and the underlying document is critical.
Preexisting Documents
A party generally cannot take an otherwise discoverable document and make it privileged simply by sending it to a lawyer.
Suppose a company has a financial report created in the ordinary course of business.
If the company later sends that report to its lawyer, the report does not automatically become privileged.
Its original character remains relevant.
Attorney-client privilege is not a mechanism for retroactively transforming ordinary business records into privileged material.
Waiver of Attorney-Client Privilege
Privilege can be waived.
Waiver generally occurs when the holder of the privilege acts inconsistently with maintaining confidentiality or otherwise intentionally relinquishes the protection.
For example, voluntarily disclosing a privileged communication to an unrelated third party may waive the privilege.
Waiver can have significant consequences in litigation.
The precise scope of waiver can vary.
A disclosure may sometimes affect only the particular communication disclosed, while in other circumstances the waiver may extend to related communications.
Who Holds the Privilege?
The attorney-client privilege generally belongs to the client, not the attorney.
This distinction matters.
The lawyer has a professional duty to protect confidential client information, but the evidentiary privilege itself is generally controlled by the client.
The client may assert the privilege.
The client may also waive it.
For a corporation, the corporation generally controls the privilege.
Lawyers Cannot Simply Waive the Client’s Privilege
Because the privilege belongs to the client, an attorney ordinarily cannot unilaterally waive the client’s attorney-client privilege simply because the attorney possesses the communication.
Counsel must generally act consistently with the client’s privilege rights and applicable professional duties.
The exact rules governing authority to waive privilege can depend on the circumstances and the type of client involved.
Inadvertent Disclosure
Large-scale litigation creates a practical problem.
A party may accidentally produce a privileged email among thousands or millions of documents.
Federal Rule of Evidence 502 addresses certain circumstances involving inadvertent disclosure.
Under Rule 502(b), inadvertent disclosure does not result in waiver in federal proceedings when:
- the disclosure is inadvertent;
- the holder of the privilege or protection took reasonable steps to prevent disclosure; and
- the holder promptly took reasonable steps to rectify the error.
The Cornell text of Federal Rule of Evidence 502 provides the federal framework for these issues.
This rule is especially important in modern e-discovery.
Rule 502 and Court Orders
Rule 502 also permits certain agreements and court orders concerning disclosure of privileged or protected information.
A court order can provide particularly valuable protection in complex litigation involving enormous document collections.
Parties may agree on procedures for:
- inadvertent disclosure;
- clawback;
- privilege review;
- and treatment of mistakenly produced materials.
The goal is to reduce unnecessary litigation over accidental disclosures.
Clawback Agreements
A clawback agreement is an arrangement under which parties establish procedures for returning or destroying privileged material that is inadvertently produced.
For example, the parties might agree that if a producing party identifies a privileged document after production, it can notify the receiving party and request its return or destruction.
The receiving party may then be required to stop using the document while the privilege claim is resolved.
Clawback procedures can significantly reduce the risk associated with large-scale document productions.
Selective Disclosure and Fairness
Privilege waiver can become complicated when a party voluntarily discloses part of a privileged communication.
A party generally should not be able to selectively disclose favorable portions of a privileged communication while simultaneously using privilege to hide unfavorable portions when fairness requires broader disclosure.
Courts may therefore examine whether a partial disclosure creates a broader waiver.
Rule 502 also contains provisions addressing certain subject-matter waiver issues.
Subject-Matter Waiver
A particularly important concept is subject-matter waiver.
If a party discloses a privileged communication concerning a particular subject, the opposing party may argue that fairness requires disclosure of additional communications concerning the same subject.
But federal law does not treat every disclosure as automatically waiving every communication on the same topic.
Rule 502(a) limits subject-matter waiver in federal proceedings to circumstances involving an intentional disclosure that is itself made in a federal proceeding or to a federal office or agency and concerns the same subject matter, where fairness requires consideration of the undisclosed communications together.
The details matter.
The Crime-Fraud Exception
Attorney-client privilege does not protect communications used to further certain criminal or fraudulent conduct.
This is commonly called the crime-fraud exception.
The principle is straightforward:
The privilege exists to facilitate lawful legal advice, not to allow a person to use a lawyer’s services to facilitate a crime or fraud.
For example, communications seeking assistance in carrying out an ongoing fraudulent scheme may fall outside the privilege.
The existence of the exception does not mean that a lawyer’s knowledge of a client’s past wrongdoing automatically destroys privilege.
The precise application depends on the nature and purpose of the communications.
Legal Advice Concerning Past Conduct
A client may confidentially tell a lawyer about past conduct and ask what legal consequences follow.
That communication can potentially be privileged even if the underlying conduct was unlawful.
For example:
I violated the reporting requirement last year. What legal consequences could follow, and what should I do now?
The client is seeking legal advice about existing circumstances.
That is fundamentally different from:
How can I continue violating the reporting requirement without being detected?
The latter may implicate the crime-fraud exception.
The distinction between advice concerning past conduct and assistance in furthering ongoing or future wrongdoing can be critical.
Joint Clients
Sometimes two or more clients share a lawyer.
For example, two business partners may jointly retain one attorney concerning a transaction.
Communications among the joint clients and their common lawyer may receive privilege protection when the requirements are satisfied.
But joint representation creates special issues concerning:
- control of the privilege;
- later disputes between the clients;
- conflicts of interest;
- and whether one client may later assert privilege against another concerning communications made during the joint representation.
The exact rules vary by jurisdiction.
Common Interest
Separate parties may sometimes share privileged information under a common-interest doctrine or similar rule without necessarily waiving privilege.
This may occur when parties with aligned legal interests coordinate their legal positions.
For example, two defendants with closely aligned legal interests may exchange certain privileged communications through their attorneys.
The doctrine is not simply a general “business interest” exception.
Its application depends on the relevant jurisdiction and the nature of the shared legal interest.
Common Interest Is Not the Same as Common Business Interests
Two companies may have a shared commercial objective without having a sufficiently aligned legal interest to preserve privilege.
For example, businesses cooperating on a commercial transaction are not automatically entitled to exchange privileged communications merely because they both want the transaction to succeed.
The analysis concerns the legal interests being coordinated.
Former Clients
The attorney-client privilege does not necessarily disappear immediately when an attorney’s representation ends.
Confidential communications made during the attorney-client relationship may remain protected.
This is distinct from the lawyer’s continuing professional duties concerning former-client confidentiality.
The precise treatment of privilege after representation ends can depend on the nature of the communication and applicable law.
The Privilege After the Client’s Death
The privilege may survive the client’s death.
The Supreme Court addressed this issue in Swidler & Berlin v. United States, 524 U.S. 399 (1998).
The Court recognized that the attorney-client privilege ordinarily survives the client’s death.
This reflects the broader purpose of encouraging clients to communicate candidly with lawyers without fearing that those communications will later become available simply because the client dies.
There are circumstances in which privilege may be affected by disputes involving the deceased client’s estate or other legal interests, but death alone does not automatically terminate the privilege.
Attorney-Client Privilege Versus Attorney Work Product
Attorney-client privilege and the work-product doctrine are related but distinct.
Attorney-client privilege protects qualifying confidential communications between attorney and client concerning legal advice.
The work-product doctrine protects certain materials prepared in anticipation of litigation or for trial.
The distinction can be summarized as follows:
| Attorney-Client Privilege | Work-Product Doctrine |
|---|---|
| Protects qualifying confidential communications | Protects qualifying litigation-preparation materials |
| Focuses on attorney-client communications | Can protect materials prepared by attorneys and certain others |
| Exists to facilitate legal advice | Exists to protect litigation preparation |
| Generally belongs to the client | Protection is generally asserted by the party whose litigation preparation is involved |
| Does not require pending litigation | Generally requires preparation in anticipation of litigation |
| May protect legal advice communications | Can protect mental impressions, strategies, and factual work product |
The Cornell explanation of the attorney work-product doctrine provides a useful comparison.
A Communication Can Involve Both Protections
Some materials may implicate both attorney-client privilege and work-product protection.
For example, a lawyer may send a client an email providing legal advice concerning a pending lawsuit.
The email may involve:
- confidential attorney-client communication; and
- litigation-related legal analysis.
The two doctrines remain legally distinct even when they overlap.
Attorney-Client Privilege Versus Confidentiality
Attorney-client privilege should also be distinguished from the lawyer’s broader duty of confidentiality.
Attorney-client privilege concerns compelled disclosure in legal proceedings and related contexts.
Professional confidentiality obligations are broader.
A lawyer may have ethical duties not to reveal confidential information even when a particular communication is not protected by the evidentiary privilege.
Therefore:
Not every confidential client communication is necessarily privileged, and privilege does not exhaust a lawyer’s confidentiality obligations.
Attorney-Client Privilege and Discovery
In civil litigation, privilege functions as an important limitation on discovery.
Rule 26(b)(1) generally permits discovery of relevant, nonprivileged information within the scope of proportional discovery.
The word nonprivileged is critical.
A document may be:
- relevant;
- important;
- highly probative;
- and responsive to a discovery request,
yet still be protected from disclosure by attorney-client privilege.
Responding to a Discovery Request
Suppose a plaintiff requests:
All communications between the defendant and its attorneys concerning this lawsuit.
The defendant may have a legitimate privilege objection.
But simply saying:
PRIVILEGED.
may not be sufficient.
The party must comply with the applicable procedural requirements for asserting privilege.
This can include identifying withheld materials sufficiently to allow the opposing party to evaluate the claim without revealing the protected substance.
Privilege Is Not a Substitute for a Discovery Objection
Privilege should be asserted carefully.
A party should not use attorney-client privilege as a general objection to avoid producing nonprivileged information.
For example, suppose a lawyer possesses:
- an ordinary business contract;
- a publicly available government report;
- a nonprivileged invoice;
- and a privileged memorandum analyzing the legal consequences of the contract.
The mere fact that all four documents are in the lawyer’s file does not make all four privileged.
Privilege applies according to the nature of the material.
Attorney-Client Privilege and Experts
Attorney-client privilege can become complicated when experts are involved.
Communications between counsel and testifying experts are generally governed by the specialized expert-discovery rules in Rule 26(b)(4), rather than simply being treated as ordinary attorney-client communications.
As discussed in expert discovery, Rule 26(b)(4)(C) protects certain attorney-expert communications but expressly leaves some categories discoverable.
This distinction is particularly important because a testifying expert is not ordinarily the attorney’s client.
Attorney-Client Privilege and Third-Party Consultants
A third-party consultant may sometimes participate in a privileged legal communication if the consultant’s involvement is reasonably necessary to facilitate the lawyer’s provision of legal advice.
But simply hiring a consultant does not automatically extend privilege.
Courts may examine:
- the consultant’s role;
- the purpose of the communication;
- whether the consultant was necessary to the legal advice;
- and whether confidentiality was maintained.
Government Lawyers and Government Clients
Attorney-client privilege can apply in government settings, although the identity and interests of the client may raise special questions.
A government lawyer may represent:
- an agency;
- a department;
- a government entity;
- or another authorized governmental client.
Communications between government lawyers and officials or employees can potentially receive privilege protection when the applicable requirements are satisfied.
Privilege and Regulatory Investigations
Attorney-client privilege can become particularly important during regulatory or internal investigations.
A company may ask counsel to investigate:
- potential legal violations;
- regulatory compliance;
- employee misconduct;
- financial reporting issues;
- or other legal risks.
The privilege analysis depends on the purpose and nature of the communications.
Merely describing an investigation as “legal” does not automatically make every related document privileged.
Investigations Conducted by Lawyers
When lawyers conduct internal investigations, courts may examine whether the communications were made for the purpose of obtaining legal advice.
Upjohn is especially important in this context.
The privilege can protect communications between corporate counsel and employees made to gather information for the purpose of providing legal advice to the corporation.
But underlying facts and preexisting documents remain distinct from the protected communications themselves.
Privilege and Corporate Records
Corporate records can present difficult privilege questions.
Consider a board meeting.
The company may have:
- ordinary business minutes;
- financial materials;
- legal advice from counsel;
- attorney memoranda;
- and communications about pending litigation.
Not everything associated with the meeting is necessarily privileged.
Courts examine the specific communication or document and its purpose.
Privilege and Draft Documents
Draft documents can raise additional issues.
A draft contract circulated internally may be an ordinary business document.
A confidential email from counsel explaining the legal consequences of proposed language may be privileged.
A lawyer’s draft memorandum prepared for the client may potentially be privileged or work product depending on its purpose and applicable law.
The label “draft” alone does not determine the result.
Privilege and Communications With Former Employees
Former employees can create complicated privilege issues during corporate litigation.
A former employee may possess information relevant to the company’s case.
Corporate counsel may communicate with that person, but the privilege analysis depends on the circumstances and applicable law.
The fact that someone once worked for the corporation does not automatically mean every later communication with corporate counsel belongs to the corporation’s privilege.
Waiver Through Conduct
Privilege can sometimes be lost through conduct that is inconsistent with maintaining confidentiality.
Examples can include:
- voluntarily disclosing a privileged communication to an adversary;
- publicly revealing legal advice;
- using privileged advice offensively in litigation;
- or intentionally producing privileged material.
Courts generally examine the circumstances carefully.
Putting Legal Advice at Issue
A party can sometimes place privileged legal advice at issue by making its legal advice or reliance on counsel part of its claim or defense.
For example, a party might assert:
We acted this way because our lawyer told us the conduct was lawful.
That assertion may create a privilege problem because the party is attempting to use legal advice as part of its substantive position.
A party generally cannot selectively use favorable legal advice while simultaneously preventing the opposing party from examining communications necessary to evaluate that assertion.
The exact scope of any resulting waiver depends on applicable law and the circumstances.
The Crime-Fraud Exception Versus Waiver
These concepts should not be confused.
Waiver generally occurs because the privilege holder has acted inconsistently with maintaining confidentiality.
The crime-fraud exception concerns the nature and purpose of the communication itself.
A communication made to facilitate certain criminal or fraudulent conduct may fall outside the privilege even if the client never voluntarily disclosed it.
Burden of Establishing Privilege
The party asserting attorney-client privilege generally bears the burden of establishing that the privilege applies.
This is important in discovery disputes.
A party cannot simply label every communication with counsel as privileged.
The party may need to establish facts showing:
- who participated;
- their relationship;
- the purpose of the communication;
- the confidential nature of the exchange;
- and the legal nature of the advice involved.
Privilege logs and supporting declarations may become important when the claim is disputed.
Courts Interpret Privilege Carefully
Privileges restrict access to potentially relevant evidence.
For that reason, courts generally apply privilege doctrines carefully rather than assuming that every arguably confidential communication is protected.
At the same time, courts recognize that the privilege would be ineffective if parties could defeat it through overly broad interpretations of what constitutes a disclosure.
The resulting analysis is highly fact-specific.
Common Mistakes Concerning Attorney-Client Privilege
Assuming everything sent to a lawyer is privileged
It is not.
Assuming everything created by a lawyer is privileged
It is not.
Confusing facts with communications
A client cannot normally shield an underlying fact simply because it was communicated to counsel.
Copying unnecessary third parties
Adding unrelated people to a privileged communication can jeopardize confidentiality.
Treating business advice as legal advice
A lawyer’s participation does not automatically convert business communications into privileged communications.
Assuming privilege belongs to the lawyer
The privilege generally belongs to the client.
Ignoring waiver
Voluntary disclosure can destroy or limit protection.
Confusing privilege with work product
The two doctrines have different purposes and requirements.
Assuming an inadvertent disclosure always destroys privilege
Federal Rule of Evidence 502 can protect certain inadvertent disclosures when its requirements are satisfied.
Using privilege as a blanket discovery objection
Only qualifying information is protected.
A Practical Example
Imagine that a corporation receives a government demand concerning its accounting practices.
The corporation’s general counsel begins an internal investigation.
The lawyer interviews several employees and asks questions designed to determine what happened and what legal obligations the company may have.
An employee provides confidential information to the lawyer.
The lawyer later sends the company’s executives a confidential memorandum explaining the potential legal consequences.
Several different categories of information now exist.
The employee’s underlying factual knowledge is not automatically privileged.
The employee’s confidential communication to counsel made for the purpose of obtaining legal advice may be privileged.
The lawyer’s confidential legal advice to the company may also be privileged.
A preexisting accounting spreadsheet reviewed by the lawyer does not become privileged merely because counsel examined it.
A memorandum prepared by counsel in anticipation of litigation may also implicate the work-product doctrine.
The proper analysis therefore requires examining each communication or document rather than treating the entire investigation as privileged.
Attorney-Client Privilege in the Digital Age
Digital communication has made privilege both more important and more difficult to administer.
A single privileged email can be:
- forwarded;
- copied;
- attached to another email;
- stored on a cloud platform;
- synchronized across devices;
- included in an electronic archive;
- or accidentally produced during discovery.
Organizations therefore need effective information-management practices.
Counsel may also need to establish procedures concerning:
- privilege review;
- email collection;
- document retention;
- access controls;
- confidential communications;
- and inadvertent production.
Attorney-Client Privilege and E-Discovery Review
Large document reviews often use dedicated teams or technology-assisted review.
Reviewers must distinguish among:
- privileged communications;
- work product;
- responsive nonprivileged documents;
- duplicates;
- irrelevant material;
- and potentially responsive documents requiring additional analysis.
A privileged document should not be withheld merely because it contains the word “attorney.”
Likewise, a responsive document should not be produced merely because it does not look like a traditional legal memorandum.
Privilege review is a substantive legal determination.
Attorney-Client Privilege and Settlement Communications
Communications with counsel concerning settlement may involve several different legal protections.
A lawyer’s advice to a client about the legal consequences of settlement may be attorney-client privileged.
A communication with the opposing party during settlement negotiations raises different issues, including the separate rules governing compromise offers and negotiations under Federal Rule of Evidence 408.
The protections should not be conflated.
Attorney-Client Privilege and Litigation Strategy
Legal strategy can also involve work-product protection.
For example, a lawyer may tell a client:
We believe the opposing party’s causation theory is vulnerable, and we should focus discovery on the underlying expert methodology.
The communication may contain both legal advice and litigation strategy.
The attorney-client privilege and work-product doctrine may overlap, but they remain distinct sources of protection.
Why Privilege Matters in Civil Procedure
Attorney-client privilege directly affects the scope of civil discovery.
Civil litigation is based on broad information exchange, but discovery does not require parties to disclose everything they know.
Privilege is one of the principal boundaries.
It reflects the legal system’s judgment that certain communications should remain protected because protecting them promotes a more important institutional interest: effective legal representation and informed compliance with the law.
Without such protection, the discovery system could undermine the very attorney-client relationship that helps parties understand and comply with their legal obligations.

Frequently Asked Questions
What does attorney-client privilege protect?
It generally protects confidential communications between a lawyer and client made for the purpose of obtaining or providing legal advice.
Does attorney-client privilege protect everything I tell my lawyer?
Not necessarily. The communication must satisfy the requirements of the applicable privilege law. Underlying facts, business information, and communications unrelated to legal advice may not be protected.
Who owns attorney-client privilege?
The privilege generally belongs to the client, who ordinarily has the authority to assert or waive it.
Does privilege apply to emails?
Yes. Emails can qualify for attorney-client privilege when they satisfy the applicable requirements. The electronic format does not prevent privilege from applying.
Does copying a lawyer on an email make the email privileged?
No. Merely copying an attorney does not transform an otherwise nonprivileged communication into a privileged one.
Are communications with corporate lawyers privileged?
They can be. Under Upjohn, qualifying communications between corporate counsel and employees can receive privilege protection when made for purposes of obtaining legal advice for the corporation and the applicable requirements are satisfied.
Are facts protected by attorney-client privilege?
Generally, no. The privilege protects qualifying communications, not simply the underlying facts discussed in those communications.
What is the difference between attorney-client privilege and work product?
Attorney-client privilege primarily protects confidential attorney-client communications concerning legal advice. The work-product doctrine protects certain materials prepared in anticipation of litigation or for trial.
Can attorney-client privilege be waived?
Yes. Voluntary disclosure to third parties, placing legal advice at issue, and other conduct can result in waiver or limitation of the privilege.
Does accidentally producing a privileged document always waive privilege?
No. Federal Rule of Evidence 502 provides protection for certain inadvertent disclosures when its requirements are satisfied, including reasonable precautions to prevent disclosure and prompt steps to rectify the error.
What is the crime-fraud exception?
It is an exception to attorney-client privilege for certain communications made to further a crime or fraud. The privilege generally does not protect using legal advice to facilitate ongoing unlawful conduct.
Does privilege survive the client’s death?
Generally, yes. The Supreme Court held in Swidler & Berlin v. United States that attorney-client privilege ordinarily survives the client’s death.
Can a lawyer waive the client’s privilege?
The privilege generally belongs to the client, so the lawyer does not ordinarily have independent authority to waive the client’s privilege simply because the lawyer possesses the communication.
What is a privilege log?
A privilege log is a disclosure used in litigation to identify information withheld on privilege or work-product grounds with enough information for the opposing party to evaluate the claim without revealing the protected substance.
Is every document in a lawyer’s file privileged?
No. Lawyers can possess nonprivileged documents, including contracts, business records, public records, and other materials that were not created as privileged communications.
Conclusion
Attorney-client privilege is one of the fundamental protections governing the relationship between lawyers and clients.
Its central principle is simple:
A client should be able to communicate candidly with a lawyer about legal matters without automatically exposing those communications to compelled disclosure.
But the doctrine is considerably more precise than the phrase “everything between a lawyer and client is confidential.”
Privilege generally protects qualifying communications, not underlying facts. It requires a genuine attorney-client relationship and a connection to legal advice. Confidentiality matters. Unnecessary third-party participation can create waiver issues. Business advice may fall outside the doctrine even when a lawyer provides it. And documents do not become privileged simply because they are sent to, reviewed by, or stored by an attorney.
The doctrine becomes particularly important in civil discovery. A party may possess enormous amounts of electronic information that is relevant to litigation, yet some of that information may be protected because it contains confidential attorney-client communications. Rule 26 and the procedures governing privilege claims provide mechanisms for asserting that protection, while Rule 502 addresses important questions concerning waiver and inadvertent disclosure.
Attorney-client privilege must also be distinguished from the work-product doctrine. The two protections often operate together, especially in litigation, but they serve different purposes and have different requirements.
Ultimately, attorney-client privilege represents a deliberate balance between two competing interests. Civil litigation seeks broad access to relevant information, while the legal system also recognizes that effective legal representation requires a protected space in which clients can tell their lawyers the truth and lawyers can provide candid legal advice. The privilege protects that space—but only within the boundaries established by law.
