Contract drafting
Draft a first contract draft (NDA, T&C, service agreement) in 5-10 minutes instead of 1-2 hours, with high quality and legal compliance.
Contract drafting represents a major part of a business lawyer's and corporate counsel's work — often 30 to 50% of billed time for recurring contracts (NDA, T&C, service agreements, distribution agreements). Generative AI now allows producing a correct legal first draft in a few minutes, compliant with applicable law and adaptable to your situation. But beware: an unreviewed AI contract is a major risk — imprecise clauses, obsolete references, missed mandatory mentions. This guide presents the secure workflow, prompts that produce solid legal output, and solutions to preserve client data confidentiality (which strictly forbids the use of free ChatGPT in firms).
Step-by-step workflow
Choose the confidentiality-appropriate solution
For sensitive contracts: never free or Plus ChatGPT. Use Claude for Work, ChatGPT Team/Enterprise, or dedicated legal solutions (Doctrine AI, Predictice). Verify data isn't used for training and activate opt-outs.
Define contract parameters
Before requesting drafting: contract type, parties, applicable law, amounts/durations, specific necessary clauses (non-compete, exclusivity, IP, GDPR). It's the brief that determines quality.
Have a structured first draft produced
Request a contract with standard structure: preamble, definitions, object, party obligations, price/duration, IP, confidentiality, GDPR if applicable, termination, applicable law, jurisdiction. Verify all mandatory mentions are present.
Verify legal references
Critical step: always verify every law article cited, every case law mentioned, every effective date. AI can invent references. Cross-check with official databases before any operational use.
Refine and validate
Iterate with AI on clauses requiring adjustment (e.g., adapt non-compete clause to precise situation, harden/soften penalties). Final human validation essential. For high-stakes contracts, double validation by a colleague.

Frequently asked questions
Can a lawyer use free ChatGPT to draft a contract?
No, that's a violation of professional secrecy and probably GDPR. The free and Plus versions of ChatGPT may use your data to train models. Only ChatGPT Team/Enterprise, Claude for Work or dedicated legal solutions (Doctrine AI, Predictice) contractually guarantee non-use of data.
Can AI replace a lawyer for contract drafting?
For very standardized and low-stakes contracts (simple NDA, classic service between individuals/small businesses): yes in some cases, subject to validation by a professional. For high-stakes, custom contracts, or those with legal specifics: no, AI produces a draft that only a lawyer can transform into an enforceable, adapted contract. Legal responsibility remains human.
Can AI invent law articles or case law?
Yes, that's the major risk. Several lawyers have been sanctioned (USA, Canada, France) for citing non-existent rulings generated by AI. The absolute rule: always verify each reference in an official database (official court databases, government legal portals) before any use. Unverified reference = unusable.
Are AI-generated contracts legally enforceable?
A contract is enforceable if it meets contract law conditions (consent, capacity, object, cause), regardless of whether it was drafted by a human or AI. But in case of dispute, drafting responsibility falls on the lawyer or counsel who validated it. AI is just a tool — legal responsibility remains 100% human.
