Every OurPrenup agreement is built for the laws where you live.
Start your Arizona prenupYes — prenuptial agreements are legally enforceable in Arizona under the Uniform Premarital Agreement Act (UPAA) (ARS § 25-201). To be valid, the agreement must be in writing, signed voluntarily by both partners, and made with fair financial disclosure. It should be notarized (strongly recommended, though not legally required), and both partners should have a real opportunity to review it well before the wedding.
Most property acquired during the marriage is owned 50/50 unless your agreement says otherwise.
Yes. Arizona enforces prenuptial agreements under the Uniform Premarital Agreement Act (UPAA). The governing law is ARS § 25-201. The agreement must be in writing and signed by both partners, entered into voluntarily, and made with fair financial disclosure.
Notarization is not strictly required in Arizona, but strongly recommended — a notarized agreement is significantly harder to challenge in court, and OurPrenup's Arizona signing instructions include it.
No — Arizona does not require witnesses for a prenuptial agreement. Both partners' signatures (ideally notarized) are what matter.
No — Arizona does not require either partner to hire a lawyer for a valid prenup. Independent review is still recommended, and every OurPrenup agreement documents that both partners had the opportunity to seek counsel.
Yes. Arizona is a community property state — without an agreement, most property acquired during the marriage is owned 50/50. A prenup lets you set your own rules for what stays separate and what is shared.
Yes — Arizona allows couples to set, limit, or waive spousal support in a prenup, subject to fairness review and statutory safety valves that protect a spouse from being left in hardship. OurPrenup offers a full waiver, payment formulas with amounts you choose, or leaving support to state law.
Each partner must make a fair and reasonable disclosure of their assets, debts, and income before signing. Hiding assets is the fastest way to make a prenup unenforceable in Arizona. OurPrenup builds sworn financial disclosure schedules for both partners into every agreement.
Arizona has no fixed statutory deadline, but signing well before the wedding matters: agreements signed days before a wedding are the easiest to attack as pressured. Most attorneys recommend having the agreement finished at least 30 days before the wedding.
