Verified brief drafting and authority research
Westlaw Brief Builder helps litigators research supporting authorities, map arguments to claims, draft briefs and motions, and validate citations, quotes, and legal assertions against Westlaw and Practical Law sources.
Why the human is still essential here
Lawyers remain in control of strategy, choose which arguments and authorities to pursue, confirm relevance, and bear responsibility for final verification and filing decisions.
