Claude for Due Diligence Document Registers

Produce a register of requested versus received evidence, stale documents, and unanswered questions. Keep an audit trail of source filenames.

Published September 22, 2026 · Dr. Connor Robertson

What to provide

Data room index, request list, received files, and version dates.

Starting prompt

Compare the diligence request list with this data room index. Mark received, partial, missing, or outdated; cite filenames and dates; propose one follow-up question per gap.

Trial case

Add two similarly named files from different periods. The register should identify each period, flag the older version, and show which request remains unanswered.

Review gate

The deal team confirms document completeness and routes accounting, legal, and tax conclusions to the respective specialists.

How to score the result

Open requests at each diligence checkpoint and duplicate asks sent to the seller.

Use the current approved source and keep it available to the reviewer. Check a small set of finished outputs against the previous process before adopting this workflow.
