Attorney-Client Privilege vs. Work Product Doctrine
A detailed comparison of these two evidence rules, including key differences, exam strategies, and guidance on when to apply each.
Overview
Attorney-client privilege and the work product doctrine are both protections against disclosure, but they arise from different sources, protect different things, and can be overcome under different circumstances. Understanding the distinction is essential for both evidence and civil procedure exams.
Attorney-client privilege is an evidentiary privilege that protects confidential communications between a client and their attorney made for the purpose of obtaining or providing legal advice. The privilege belongs to the client, not the attorney, and can only be waived by the client. It applies in all proceedings (trial, deposition, grand jury) and protects the communication itself, not the underlying facts. The privilege can be overcome only by waiver or the crime-fraud exception.
The work product doctrine, established in Hickman v. Taylor (1947) and codified in Federal Rule of Civil Procedure 26(b)(3), protects materials prepared by or for a party or their representative in anticipation of litigation. Unlike attorney-client privilege, work product protection is not absolute. Ordinary work product (factual material) can be discovered upon a showing of substantial need and inability to obtain the equivalent without undue hardship. Opinion work product (the attorney's mental impressions, conclusions, opinions, and legal theories) receives near-absolute protection and is virtually never discoverable. Work product protection can be asserted by either the attorney or the client.
Key Differences
| Aspect | Attorney-Client Privilege | Work Product Doctrine |
|---|---|---|
| Source | Common law evidentiary privilege (also codified in some jurisdictions) | Federal Rule of Civil Procedure 26(b)(3); Hickman v. Taylor |
| What is protected | Confidential communications between attorney and client | Materials prepared in anticipation of litigation |
| Can it be overcome? | Only by waiver or crime-fraud exception (absolute protection) | Ordinary work product: yes, with substantial need; Opinion work product: virtually never |
| Who holds it | The client (only client can waive) | Both attorney and client can assert |
| Scope | Covers communications even outside litigation context | Only covers materials prepared in anticipation of litigation |
Exam Tips
On exams, analyze attorney-client privilege first, then work product as a separate protection. A document can be protected by both, one, or neither. The classic exam pattern involves a memorandum from attorney to client: the communication may be privileged, and the memo as a document may be work product. If privilege is waived (e.g., the client shares the communication with a third party), work product protection may still apply. Remember: privilege protects the communication, while work product protects the document or material. For work product, always distinguish between ordinary (facts) and opinion (mental impressions) work product, as the standard for overcoming each differs dramatically.
When to Apply Which
Apply attorney-client privilege when the issue is whether a confidential communication between attorney and client must be disclosed. Apply the work product doctrine when the issue is whether litigation preparation materials must be produced in discovery. The two protections often overlap but are analytically distinct. A key scenario: if a client tells their lawyer facts in confidence, the communication is privileged, but the underlying facts are not. If the lawyer then writes a memo analyzing those facts, the memo is work product. The opposing party can depose the client about the facts but cannot obtain the privileged communication or the attorney's mental impressions.
