A qualified protection under civil procedure rules that shields materials prepared by or for an attorney in anticipation of litigation from routine discovery. The doctrine covers both factual compilations and opinion work product reflecting mental impressions and strategy. An opposing party may overcome the protection only by demonstrating substantial need for the materials and an inability to obtain their substantial equivalent without undue hardship.

Attorney Interview Summaries Withheld
After a cargo vessel fire, Woodridge Manufacturing's counsel interviewed crew members and dockworkers to prepare a defense. The attorney prepared written summaries of those interviews. When cargo owners later sued and sought the summaries in discovery, the court denied the motion because the summaries were prepared in anticipation of litigation and the owners made no showing of substantial need or undue hardship in obtaining the facts elsewhere.
Corporate Investigation Notes Protected
Willowbrook Capital's in-house counsel directed project managers to have engineers and technicians participate in confidential interviews after a product failure that was expected to produce litigation. Counsel prepared a root-cause report and interview notes. When plaintiffs later moved to compel production, the court denied the motion because the materials were prepared in anticipation of litigation and the plaintiffs failed to show substantial need or inability to obtain equivalent facts through other discovery.
Inadvertent Production Triggers Return
Winterhaven Logistics' outside counsel inadvertently produced a memorandum containing counsel's analysis of settlement strategy and anticipated deposition tactics during expedited document production. Upon discovering the error, counsel immediately notified opposing counsel and demanded return of the document. The court granted the protective order requiring sequestration and return because the memorandum constituted protected work product prepared in anticipation of litigation.

Common questions
Frequently Asked
4
How does work product immunity differ from the attorney-client privilege?+
Work product immunity protects materials prepared by or for an attorney in anticipation of litigation regardless of whether they involve client communications. The attorney-client privilege applies only to confidential communications between attorney and client for the purpose of obtaining legal advice. Work product protection is qualified while the privilege is absolute.
Supporting sources
What showing must a party make to overcome work product protection?+
The requesting party must demonstrate substantial need for the materials and an inability to obtain their substantial equivalent without undue hardship. Even when that showing is made, opinion work product reflecting mental impressions and legal theories receives heightened protection and is rarely ordered produced.
Does work product protection apply to materials originally created for a non-litigation purpose?+
No. Materials must be prepared in anticipation of litigation. Documents created in the ordinary course of business retain no work product protection even if they later become relevant to anticipated litigation.
Supporting sources
What happens when work product is inadvertently produced during discovery?+
Upon prompt notification of the claim, the receiving party must return, sequester, or destroy the material and refrain from further use until the claim is resolved. The rule requires reasonable steps to retrieve any copies already disseminated.
