Drafting contracts is one of the most time-consuming tasks in legal and business operations. AI can generate first drafts, review existing documents, flag unusual clauses, and translate legalese into plain English — in minutes rather than hours. Here’s how to use it safely and effectively.
What AI Can and Cannot Do in Contract Drafting
AI can: Generate first drafts from templates, suggest standard clauses, explain complex language, flag deviations from standard terms, and compare two contract versions.
AI cannot: Provide legal advice, guarantee enforceability, understand jurisdiction-specific nuances without guidance, or replace a qualified solicitor for significant transactions.
Generating a Contract First Draft
Claude is the best model for legal drafting due to its large context window and instruction-following ability:
Draft a [contract type] between [Party A: describe] and [Party B: describe]. Key terms: [list your key commercial terms]. Governing law: England and Wales. Include standard clauses for: definitions, obligations of each party, payment terms, intellectual property ownership, confidentiality, limitation of liability, and termination. Use formal legal language.
Always treat the output as a starting point, not a final document.
Reviewing Contracts You’ve Received
Review this contract [paste or upload PDF]. Flag: unusual or non-standard clauses, one-sided provisions, potential liabilities, ambiguous language, and anything that would disadvantage [your party]. Summarise in plain English. List issues by severity: Critical / High / Medium / Low.
This pre-screening takes 2 minutes and surfaces issues before your legal team spends time on a full review.
Plain English Summaries
For non-lawyers who need to understand what they’re signing:
Summarise this contract in plain English in bullet points. Explain: what each party is agreeing to do, what they’re agreeing not to do, how long it lasts, how it can be ended, and what happens if there is a dispute. Use plain language — no legal jargon.
NDAs and Standard Agreements
For simple, lower-risk documents like NDAs, mutual confidentiality agreements, or basic service agreements, AI can generate near-final drafts. Use this approach:
- Generate the first draft with AI
- Review it yourself against your standard template
- Have a solicitor review any clause you’re uncertain about
- Save the approved version as your standard template
