Legal Research Assistant

Customer brief

A law firm wants a research assistant over case law, statutes and the firm's prior briefs. Must cite with pinpoint accuracy. Hallucinated citations are career-ending. Must handle multi-jurisdiction queries.

Discovery questions

Ask these before designing a solution.

  • 1Which jurisdictions and how are they structured (federal, state, EU)?
  • 2What is the citation format required (Bluebook, etc.)?
  • 3How current must the law be — same day, week, month?
  • 4Are prior briefs and memos in scope?
  • 5What is the tolerance for hallucinated citations?
  • 6Is there an existing legal research platform to integrate or replace?
  • 7What is the attorney workflow — research, drafting, both?
  • 8How is attorney-client privilege protected?
Constraints
  • Zero tolerance for hallucinated citations
  • Pinpoint citations (page, paragraph) required
  • Multi-jurisdiction
  • Attorney-client privilege protection
  • Law currency — daily updates for statutes
  • Must integrate into attorney workflow, not replace judgment
Requirements
  • Structured citation with verified source (not model-generated citation)
  • Hybrid retrieval: vector for semantic + exact for citation numbers
  • Citation verification step — does the cited case/section actually exist and contain the proposition?
  • Jurisdiction filter at query time
  • Privilege log — every query and source logged
  • Refusal when no verified source found
  • Human-in-the-loop for adversarial arguments
