Can I Use an AI-Drafted Prenup?
As a starting draft, yes. As the document you actually sign — not without an attorney licensed in your state. A prenup is unusual among contracts: it's tested only once, years later, at the worst possible moment, by a judge applying your state's specific fairness and procedure rules. Defects that would be harmless in an ordinary contract — a missing disclosure schedule, a skipped waiting period, an overreaching clause — can void a prenup entirely. And in several states, having independent lawyers on each side is itself part of what makes the agreement stick.
Why prenups punish drafting mistakes more than any other contract
Most contracts get performed and forgotten. A prenup exists for exactly one scenario: a divorce or death, often decades after signing, where one side now has every incentive to attack it. Courts oblige by scrutinizing prenups harder than ordinary agreements — asking not just what was signed but how: Was it voluntary? Was there fair financial disclosure? Was it unconscionable? Did each side understand what they were giving up? An AI can produce clean-looking clauses; it cannot make the signing process meet your state's procedural requirements — and the process is where prenups die.
The state-law minefield
- Procedure rules differ sharply. California, for example, requires a waiting period between receiving the final agreement and signing it, and makes a spousal-support waiver unenforceable unless the waiving party had their own lawyer. New York requires the agreement to be acknowledged with deed-level formality. A generic AI draft knows none of this unless you did — and asks for none of it.
- Financial disclosure is the classic killer. Most states condition enforceability on fair and reasonable disclosure of each side's assets, debts and income. AI drafts routinely include a boilerplate "each party has disclosed" recital with no actual schedules attached — a sentence that claims disclosure happened is not disclosure.
- Some things a prenup simply can't do. Child support and custody can't be predetermined; provisions that "promote divorce" or regulate personal conduct are unenforceable in many states. AI drafts, trained on internet templates, include these routinely.
- Independent counsel is more than advice. In several states, each party having (or knowingly waiving) their own attorney is a factor courts weigh — and for certain waivers, a requirement. This is the rare contract where the lawyer's involvement is part of the product's validity, not just its quality.
The sensible workflow
Use AI for what it's genuinely good at here: producing a first draft that forces the real conversation — what's separate property, what happens to the house, how you'd treat future earnings. That conversation is the valuable part, and having a concrete draft makes it easier. Then bring the draft to an attorney licensed in the state where you'll marry or live: they'll fix the state-specific mechanics, attach real disclosure schedules, run the signing procedure correctly, and — where the rules call for it — put independent counsel on each side. Reviewing and finalizing an existing draft costs a fraction of drafting from scratch.
Is there a case for skipping the lawyer?
Honestly, less than for almost any other document we cover. A prenup that fails validity gives you the worst of both worlds: you relied on protection that evaporates precisely when you need it, and your state's default divorce rules — the thing you were trying to opt out of — apply anyway. If the stakes are low enough that this outcome doesn't bother you, you may not need a prenup at all; if they're high enough that you want one, they're high enough to have it done right.
