Good to know

The act was renumbered and amended by Chapter 366, 2024 General Session, and the current version is effective September 1, 2024.

An issue of fraud is decided by the court as a matter of law (Utah Code 81-3-205(3)).

What this means in practice

Sign well before the wedding. Courts may look closely at an agreement presented shortly before the ceremony, and some states set a minimum time between receiving the final draft and signing it. Leaving time to read, ask questions and negotiate helps show the agreement was entered voluntarily.

Exchange full financial information in writing. A schedule of each party's assets, debts and income attached to the agreement creates a record of what was disclosed. Where a party gives up the right to more information, that waiver should usually be in writing and signed as well.

Consider separate lawyers for each party. Even where independent counsel is not strictly required, having each person advised by their own attorney can make the agreement harder to challenge later. Terms about child support or custody are generally not binding, and spousal support waivers can face extra scrutiny, so a local attorney can confirm what is allowed.

General information, not legal advice. Laws change, and cities can add their own rules, so check the current statute before you rely on it.
