Can AI write a legally binding contract?
Yes to drafting, and yes to the signature, but those are two different questions and only one of them is about AI. A contract drafted by AI and signed electronically is as binding as one drafted by a person, provided the signing meets the requirements of the US ESIGN Act or eIDAS in the EU: intent to sign, consent to do business electronically, a record associating the signature with the document, and retention of that record. What AI cannot do is tell you the terms are correct for your situation, which is legal advice and is a different profession.

What makes the signature binding
Not the drafting. Under ESIGN and eIDAS a signature is enforceable when there is clear intent to sign, the parties consented to electronic dealing, the signature is associated with the specific record, and that record is retained and reproducible. In practice that means a per-version content hash so each party demonstrably signed exact wording, verification of who signed, and a certificate of completion attached to the final document.
Where AI-drafted contracts actually go wrong
Rarely in enforceability, usually in the commercial terms. A model asked to draft a services agreement will produce something fluent that quietly omits a liability cap, or a fee schedule that does not match what you sell. The fix is structural rather than a better model: the language can be generated, the money should not be. In DocuDeal every figure is computed in code from your own catalog and the model never produces a number.
The sensible way to use it
Have a lawyer review your standard paper once, import it, and generate against it. You get the speed on every subsequent document and the review happened where it was worth paying for. Generating novel contract terms for a novel situation and signing them unreviewed is where people get hurt, and that is true whether a model or a junior wrote them.
What still needs a human or a notary
Notarised and in-person signing still needs a notary. Some jurisdictions and document types, including certain property, probate and family matters, exclude electronic signature entirely. And no AI output is advice on enforceability in your jurisdiction.
| Question | Answer |
|---|---|
| Can AI draft a contract? | Yes |
| Is an e-signature on it binding? | Yes, if ESIGN or eIDAS conditions are met |
| Does AI drafting weaken enforceability? | No. Who drafted it is not a factor |
| Can AI tell you the terms are right? | No. That is legal advice |
| Should AI calculate the fees? | No. Compute those in code from a price list |
| Does it replace a notary? | No |
General position under the US ESIGN Act and EU eIDAS. Not legal advice; requirements vary by jurisdiction and document type.
