    What people get wrong

    A prenup only helps if it holds up

    Couples sign a prenup assuming it locks in the deal, then find out years later that a court will not enforce it. The agreement is only as good as how it was written and signed — and the rules for that are stricter than most people expect.

    The short answer

    The short answer

    A prenuptial agreement is a contract signed before marriage that sets out how assets, debts, and sometimes spousal support will be handled if the couple divorces or one dies. It can override the default property rules that would otherwise apply. Whether a court enforces it depends on how it was made, and the requirements vary by jurisdiction.

    What it can and cannot cover

    A prenup typically governs property division, separate vs marital assets, debt, and in some places spousal support. It generally cannot pre-decide child custody or child support, which courts set on the child's best interests at the time. What a prenup may validly cover varies by jurisdiction — confirm locally.

    What makes one enforceable

    Enforceability commonly turns on a few things: full financial disclosure by both sides, each party having the chance for independent legal advice, no fraud or pressure, terms that are not unconscionable, and proper execution. Miss one and a court may set it aside. The exact tests vary by jurisdiction, so confirm locally.

    How it works

    1

    Disclose everything, in writing

    Both parties list their assets, debts, and income honestly. Incomplete disclosure is one of the most common reasons a prenup is later thrown out.

    2

    Give each side their own counsel and time

    Each party should have independent legal advice and sign well before the wedding, not on the eve of it. Pressure and last-minute signing undermine enforceability.

    3

    Draft and stress-test, then confirm

    Ask HAQQ privately to explain what your jurisdiction requires for a prenup to hold and to flag weak spots in a draft, then have each party's own lawyer finalize and witness it. This is legal information, not legal advice.

    FAQ

    Are prenups always enforceable?

    No — courts can set one aside for inadequate disclosure, pressure, unconscionable terms, or improper signing. Enforceability depends on how it was made and varies by jurisdiction.

    Can a prenup decide child custody or support?

    Generally no — courts set child custody and support on the child's best interests at the time, so a prenup usually cannot bind those terms in advance. This varies by jurisdiction.

    Do both of us need our own lawyer?

    It is strongly advisable — independent legal advice for each party is one of the main things that makes a prenup hold up. Some jurisdictions effectively require it; confirm locally.

    Can we make an agreement after marriage instead?

    Often yes — a post-nuptial agreement does a similar job after the wedding, though the requirements can be stricter. Availability and enforceability vary by jurisdiction.
