The legal profession has massively adopted generative AI since 2024, but with a particular requirement: absolute confidentiality of files and intellectual rigor that tolerates no "hallucinations". Several US law firms have been penalized for citing non-existent case law invented by ChatGPT. This guide presents the stack that respects professional secrecy, high-ROI use-cases (contracts, jurisprudence) and the method to systematically validate AI responses in a legal framework.

Why adopt AI in this profession
Standard contract drafting repetitive and time-consuming
Case law research lengthy in Lexis, Dalloz, Doctrine databases
Continuous legal watch facing legislative and regulatory changes
Large file synthesis for trial preparation
Client data confidentiality: impossible to send a file to a public LLM
