STATE GUIDE · UPDATED 2026
Every OurPrenup agreement is built for the laws where you live.
Start your Iowa prenupYes — prenuptial agreements are legally enforceable in Iowa under the Uniform Premarital Agreement Act (UPAA) (Iowa Code § 596.1). 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.
Courts divide marital property fairly (not necessarily equally) unless your agreement says otherwise.
Yes. Iowa enforces prenuptial agreements under the Uniform Premarital Agreement Act (UPAA). The governing law is Iowa Code § 596.1. 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 Iowa, but strongly recommended — a notarized agreement is significantly harder to challenge in court, and OurPrenup's Iowa signing instructions include it.
No — Iowa does not require witnesses for a prenuptial agreement. Both partners' signatures (ideally notarized) are what matter.
No — Iowa 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.
No. Iowa is an equitable distribution state — without an agreement, courts divide marital property "fairly," which is not necessarily equally. A prenup replaces that uncertainty with rules you both chose.
No. Iowa does not allow prenuptial agreements to modify or waive spousal support — Iowa Code § 596.5(2) (verbatim): 'The right of a spouse or child to support shall not be adversely affected by a premarital agreement.' Spousal support provisions are affirmatively prohibited, not merely unauthorized. OurPrenup automatically leaves support to state law in Iowa agreements.
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 Iowa. OurPrenup builds sworn financial disclosure schedules for both partners into every agreement.
Iowa 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.
Attorney-drafted prenups in Iowa commonly run $1,500–$5,000+ per couple. OurPrenup is a flat $599 per couple for a complete Iowa-specific prenuptial agreement, financial disclosure schedules for both partners, a plain-language summary, and step-by-step Iowa signing instructions — with optional online e-sign and notarization for $50.

Both parties sign the prenuptial agreement.
Have the agreement notarized. While Iowa does not legally require notarization, we strongly recommend it. Notarized agreements are significantly harder to challenge in court.
