As of 13 August 2026, AI cannot draft a UK prenuptial agreement.

What to actually do

1. Hand it to a person

   The route this page recommends

   Someone with a licence or accountable authority has to sign this before it counts.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface gets you a draft, but you cannot verify it yourself. That is the catch.

   How to actually do it

   1. Open GOV.UK guidance on getting legal advice and make a note of whether your matter is in England and Wales, Scotland or Northern Ireland.
   2. Gather both parties’ current details, intended wedding or civil partnership date, financial objectives, proposed arrangements and any concerns about future separation.
   3. Collect supporting documents for assets, debts, income, pensions, businesses, trusts, inheritances and property, and record the date and source of each valuation.
   4. Paste the supplied prompt into a chatbot, replace the jurisdiction and facts slots, and ask it to produce the working draft and solicitor handover checklist.
   5. Compare the draft’s factual statements and financial schedules against the documents you gathered, deleting any claim or figure that cannot be supported.
   6. Send the working draft and complete disclosure documents to a family solicitor for advice, independent advice for each party, revisions and advice on signing before the ceremony.

   Prompt

   I need an informational working draft for a proposed prenuptial agreement under the law of [England and Wales / Scotland / Northern Ireland]. This is not professional advice and must not be treated as a finished legal document.
   
   Use only the facts I provide. Do not invent assets, debts, valuations, children, business interests, inheritances or legal rules. First list the information that is missing or unclear. Then produce a clearly labelled working draft with neutral placeholders for anything missing.
   
   The draft should cover, where relevant:
   1. The parties and intended marriage or civil partnership.
   2. The governing jurisdiction and any jurisdictional uncertainty.
   3. Financial disclosure by each party, including assets, debts, income, businesses, pensions, trusts, inheritances and expected gifts.
   4. Property owned before the relationship and property acquired during it.
   5. Treatment of future income, savings, gifts, inheritances and business growth.
   6. Housing and living expenses.
   7. Treatment of pensions and other long-term assets.
   8. Arrangements for children, while making clear that children’s welfare cannot be predetermined by the agreement.
   9. Review events and a review date.
   10. Disclosure, independent legal advice, signing, witnesses and timing before the wedding or civil partnership.
   11. Severability, changes and dispute resolution.
   
   For every clause, add a short note explaining its purpose, the factual assumption it depends on and the issue a family solicitor must check. Flag provisions that may be unsuitable, uncertain or dependent on current law. Do not state that the agreement will be binding or enforceable. End with a solicitor handover checklist and a list of documents each party should gather. Here are the facts: [paste your facts here].
