STATE GUIDE · UPDATED 2026
Every OurPrenup agreement is built for the laws where you live. In Ohio, a prenup is formally called an antenuptial agreement.
Start your Ohio prenupYes — prenuptial agreements are legally enforceable in Ohio under Ohio law. 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. Ohio enforces prenuptial agreements under long-standing court decisions (case law). The agreement must be in writing and signed by both partners, entered into voluntarily, and made with fair financial disclosure.
Ohio law formally calls a prenup an "antenuptial agreement." It works the same way: a written contract two people sign before marriage that sets out property and financial rights.
Notarization is not strictly required in Ohio, but strongly recommended — a notarized agreement is significantly harder to challenge in court, and OurPrenup's Ohio signing instructions include it.
Witnesses are recommended (2) in Ohio, though not strictly required. More formality makes the agreement harder to challenge.
No — Ohio 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. Ohio 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.
Yes — Ohio 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 Ohio. OurPrenup builds sworn financial disclosure schedules for both partners into every agreement.
Ohio 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.
