The short answer
A contract drafted with AI can be fully binding: US law looks at the agreement, not the tool. AI saves time on the first draft of a service agreement, NDA or contractor agreement, but it invents citations and mixes up state rules. In 2023 a federal judge fined lawyers $5,000 for filing six fake cases ChatGPT made up. Check every clause and citation, and hand high-stakes deals to a lawyer.

Can AI write a legally valid contract?
Yes, a contract drafted with AI can be fully enforceable. In US contract law what matters is a real agreement: an offer, acceptance, consideration and lawful terms the parties understand. No law asks which tool typed it. The risk is elsewhere: AI writes clauses that sound legal but do not fit your situation, mixes up state rules, or invents a citation. It saves time on the first draft, not on the review.
For a small business the documents are usually the same: a service agreement, an independent contractor agreement, a simple NDA, terms and conditions for your website, an estimate that becomes a contract when signed. For some, AI and a careful read are enough; for others you still want a lawyer.
Which contracts can you draft with AI, and which need a lawyer?
| Document | AI and a review enough? | Why |
|---|---|---|
| Simple mutual NDA | Often yes | Standard structure, limited stakes |
| One-off service agreement | Yes, checking payment and liability clauses | You know the scope; AI formats it |
| Independent contractor agreement | First draft yes, review advised | Worker classification rules vary by state and agency |
| Website terms for consumer sales | Not without review | Consumer protection, auto-renewal and refund rules |
| Partnership or operating agreement, business sale, commercial lease | No | High stakes, tax consequences, custom drafting |
| Employment agreements with non-competes | No | State law differs sharply and changes often |
How do you draft a contract with AI, step by step?
- Write the deal in plain English first: who does what, for how much, by when, and what happens if someone is late or cancels. Ten lines are enough.
- Name the governing law: “agreement between two businesses, governed by Ohio law.” Without it, AI blends rules from everywhere.
- Ask for an outline before any text: scope, term, price and payment, obligations, liability, termination, disputes.
- Draft clause by clause, reading each one against your real situation.
- Ask the AI to attack its own draft from the other side’s point of view: which clauses hurt them, what is missing.
- Verify every legal citation in an official source. If you cannot find it, delete it.
- Get a lawyer’s review whenever the stakes exceed what you could afford to lose.
Does a contract need to be in writing, and are e-signatures valid?
Many contracts are valid even when oral, but some must be in writing to be enforced. Under the statute of frauds, the most common are contracts for the sale or transfer of land, contracts that cannot be completed within one year, and contracts for the sale of goods worth $500 or more. For a small business, the simple rule is: put it in writing anyway.
Electronic signatures are valid for most business contracts. The federal E-SIGN Act (15 U.S.C. 7001) says a contract may not be denied legal effect, validity or enforceability solely because an electronic signature or electronic record was used in its formation. Most states have also adopted the Uniform Electronic Transactions Act.
What mistakes does AI make in contracts?
- It invents authority. In June 2023 a federal judge in New York fined lawyers $5,000 after they filed a brief citing six court decisions that ChatGPT had made up (Mata v. Avianca). The same risk applies to any statute or case cited in your contract.
- It picks the wrong state: a Delaware venue clause or a California-specific rule in a contract between two Texas businesses.
- It writes one-sided clauses that a court may refuse to enforce, especially against consumers.
- It forgets the basics: payment terms, late fees, what happens when a client cancels the day before.
How do you review a contract AI wrote?
Read it as if the other side wrote it against you. Five questions catch most problems:
- Are the price, due dates and late fees clear and in numbers?
- What happens if either side wants out?
- Is your liability capped, and at what amount?
- Is the governing law and venue stated?
- Does every statute or case cited actually exist?

How does Extra help with contracts?
At Extra (hello-extra.com), the AI agent platform for small businesses, this is the job of Clara, the legal agent. Clara reviews a contract, annotates it, flags risky clauses, compares two versions and exports the marked-up document. She is most useful right after the first draft, whether you wrote it yourself, from a template or with AI.
Clara is not a lawyer and does not replace counsel for an operating agreement, a business sale or a dispute. The plan is $99 per month for all eight agents (see pricing).
Which prompts should you give AI to draft a contract?
The contract is only as good as the prompt. These three produce solid first drafts.
- Outline: “Outline a services agreement between two businesses, governed by Ohio law: scope, term, fees and payment, each party’s obligations, liability cap, termination, dispute resolution. No text yet.”
- Clause: “Draft the payment clause: invoice on delivery, Net 30, a late fee of 1.5% per month on overdue balances. Short sentences, no needless legalese.”
- Critique: “You are the client’s lawyer. Review this agreement and list the clauses that hurt the client, the ones missing, and every statute or case that needs checking.”
Check any late fee against your state’s limits before you use it; the 1.5% figure above is only an example for the prompt. Keep the final reviewed version as your house template: the next contract starts there, not from a fresh generation. It is faster and safer, because each clause has been checked once.
Also keep a record of what was negotiated: a contract edited through a long email thread quickly becomes unreadable. Comparing two versions before signing keeps you from signing a clause you thought was removed.
Checklist before you sign
- Governing law and venue named.
- Price, due dates and late fees in numbers, within your state’s limits.
- Termination and cancellation terms for both sides.
- A liability cap you can live with.
- Every citation checked in an official source.
- A lawyer’s review for anything you could not afford to lose.
Frequently asked questions
Is a contract written by ChatGPT legally binding?
Yes, if it reflects a real agreement and follows the law. Validity does not depend on the tool; errors do.
Is it better to start from a template?
Often yes. Check the template’s date and source, and make sure the AI does not drop a required clause while “simplifying” it.
Do you need to print and sign by hand?
Not for most everyday business contracts: e-signatures are valid under the E-SIGN Act. A few documents, like some real estate and family law papers, can have extra formalities, so check if yours is one of them.
