Work-product doctrine

Born in Hickman v. Taylor and codified at Federal Rule of Civil Procedure 26(b)(3), the doctrine has two tiers. Ordinary work product — documents and things prepared in anticipation of litigation — is discoverable only on a showing of substantial need and undue hardship. Opinion work product — counsel’s mental impressions, conclusions, and legal theories — is protected almost absolutely.

Why it matters in practice

The recurring fight is “anticipation of litigation.” Routine business documents don’t qualify just because litigation later arrived, and dual-purpose materials (an investigation run partly for business reasons) generate the hardest calls — many courts ask whether the document was prepared because of litigation. Unlike attorney-client privilege, work product extends to materials prepared by non-lawyers for the litigation effort, and disclosure to allies doesn’t automatically waive it; disclosure to adversaries does.

For fact-work teams the practical edge: your chronologies, witness outlines, and analysis memos are work product — the selection and arrangement of facts reflects counsel’s thinking — but the underlying facts are not protected, and neither are the source documents themselves. Label litigation-support artifacts accordingly and produce the records, not the analysis.

In the fact record

A fact platform sits squarely inside this doctrine: the record’s facts trace to discoverable sources, while the curation — significance calls, issue tags, examination plans — is the protected layer. Keeping the two distinguishable is good hygiene for exactly this reason.
