AI Legal Brief Writing: Faster Drafts, Stronger Arguments

This post details how Harvey's AI assists litigators in drafting briefs and motions faster and building stronger arguments, grounded in citable authority, with every citation verified by the lawyer. It emphasizes the distinction between general-purpose chatbots and grounded legal AI, highlighting the importance of verifiable sources, confidentiality, and the attorney's role in verification, judgment, strategy, and accountability. Best practices for using AI on briefs are provided, focusing on verification, grounding drafts in matter-specific information, using secure platforms, treating output as a first pass, and building verification into the workflow. Harvey supports litigation drafting by generating grounded first drafts of briefs and motions from authoritative primary law, tying arguments to real sources with traceable citations. Drafting occurs directly in Microsoft Word, allowing attorneys to draw on firm precedent and approved language. Custom agents apply firm-specific standards and drafting guidelines consistently across matters, amplifying legal judgment rather than replacing it.
