Enterprise Legal Research Agent
Legal research is a high-value, citation-heavy workflow well-suited to grounded agents. Harvey, Hebbia, Paxton, and CoCounsel from Thomson Reuters all target this space. The defining requirement: every claim must cite a verifiable source, and hallucinations are career-ending. RAG over curated legal corpora plus strict citation verification is the standard architecture.

Frequently asked questions
Aren't legal hallucinations a known scandal?
Yes — the 2023 Mata v. Avianca incident, where a lawyer submitted ChatGPT-invented cases, is the reason legal agents now mandate citation verification. Modern systems verify every cited case exists and contains the quoted text before returning an answer.
What data do legal agents ground on?
Curated legal corpora (Westlaw, Lexis, court dockets) plus firm-private documents (prior memos, precedents, contracts). Best systems cross-reference both and cite with pinpoint page/paragraph precision.
Does the agent draft pleadings?
Drafting yes — filing no. A partner/associate always reviews and signs. The liability and ethical obligations (Rule 11 in the US, similar elsewhere) remain on the human.
