Can I Use AI to Write My Will? What Could Go Wrong
AI can draft the text of a will — but the text is the easy part. A will is only valid if it's executed with your state's strict formalities (typically signing before witnesses who meet specific requirements), and if it fails, your state's intestacy rules decide who gets everything — your document becomes irrelevant. For anything beyond the simplest estate, have a licensed estate attorney review before you sign.
Why wills are different from every other AI draft
Most contracts get tested while you're alive: if something's wrong, you notice, argue, renegotiate. A will is the one document that is only ever tested after you can no longer explain what you meant, fix an error, or sign a corrected version. Every defect is permanent. That's why wills are governed by unusually strict formal requirements — and why they're the worst possible place to rely on an unreviewed draft.
The failure modes, from worst to most common
1. Invalid execution — the document simply doesn't count
Every state has execution formalities: the testator's signature, usually two witnesses (with rules about who may witness — beneficiaries witnessing can void their gifts in some states), sometimes specific signing sequences. Some states recognize handwritten (holographic) wills; many don't. Electronic wills are recognized in some states and not others. AI will happily produce a beautiful document and say nothing enforceable about how to execute it in your state. If execution fails, you die intestate — and state law's default family tree, not your wishes, distributes your estate.
2. Ambiguity your heirs will fight over
"I leave my property to my children, divided fairly." Which property? Which children — stepchildren, estranged children? What is "fairly"? You won't be there to answer. Ambiguities in wills are resolved through probate litigation, which consumes the estate you were trying to pass on. AI drafts, tuned to sound agreeable, are especially prone to warm, vague language that reads well and litigates terribly.
3. Ignoring what a will can't control
Life-insurance proceeds, retirement accounts, and jointly titled property generally pass by beneficiary designation or title, outside the will. A will that "leaves everything" to one person while your 401(k) beneficiary form still names an ex-spouse produces exactly the outcome you didn't want — and AI drafting the will text has no way to know what your beneficiary forms say.
4. Missing tax and family-situation planning
Blended families, special-needs beneficiaries (whose government benefits an outright gift can destroy), minor children, business ownership, out-of-state property — each has planning consequences a template can't see. This is judgment work, not drafting work.
A reasonable way to use AI here
Use AI to clarify your own thinking: inventory your assets, decide who gets what, understand the vocabulary (executor, guardian, residuary estate). Bring that organized picture to a licensed estate attorney in your state — many offer flat-fee review or simple-will packages — and let the professional make it valid, unambiguous, and properly executed. You'll have done the expensive thinking for free, and paid only for what actually requires a license: the judgment and the sign-off.
