Family agreements and planning under Ohio law

Ohio's family agreement landscape changed more in 2023 than in the preceding half-century: after generations of banning them, Ohio legalized postnuptial agreements. Married Ohio couples can now do what their neighbors in every surrounding state could always do — restructure their financial arrangement mid-marriage, by contract. Add Ohio's long-enforced prenups, its contract remedies for unmarried partners, and its adoption framework, and the planning toolkit here is fuller than it's ever been. This page is the map; the linked pages do the work.

Prenups — and Ohio's new postnup era

Ohio has enforced prenuptial agreements for decades under standards set by its Supreme Court: voluntary execution, full disclosure (or full knowledge) of assets, no coercion, and terms that don't promote divorce. Spousal support provisions get an extra look — they must be conscionable at the time of enforcement, not just at signing.

The 2023 revolution: Ohio amended ORC 3103.06 to permit postnuptial agreements — signed during marriage — provided they're in writing, entered freely without fraud, duress, coercion, or overreaching, made with full disclosure, and not the product of an attempt to divorce. Couples can now update a stale prenup, resolve a financial rift without divorcing, restructure around a business, or coordinate estate plans mid-marriage. The catch: the statute's requirements are exacting, the case law is young, and drafting discipline matters even more than usual in a regime this new. Full analysis: prenuptial and postnuptial agreements in Ohio.

Living together without marrying

Ohio abolished common-law marriage for relationships formed after October 10, 1991 (older ones, validly formed, survive). Modern unmarried Ohio couples get no equitable division, no support rights, no automatic inheritance — title and contract control everything. Written cohabitation agreements are enforceable and, for couples with property, disparate incomes, or shared ventures, essential: cohabitation agreements in Ohio.

Adoption in Ohio

Ohio adoption runs through probate court under ORC Chapter 3107 — stepparent, relative, agency, and private placements. Ohio's system features strict consent timing (a birth mother's consent can't be executed until at least 72 hours after birth), grounds to dispense with a parent's consent (including failure to communicate or support for a year without justifiable cause), and the Ohio Putative Father Registry — plainly: a registry where a man who may have fathered a child outside marriage must sign up within fifteen days of the birth to preserve his right to notice of an adoption. Ohio's window is among the shortest anywhere. Details: adoption in Ohio.

The planning connection

Agreements and estate plans interlock — prenups waiving elective shares, divorce revoking will and beneficiary provisions automatically under Ohio statutes, ERISA exceptions that override everything. See estate planning and divorce in Ohio.

Plan while it's easy

Brown Carrington drafts Ohio agreements with litigation-tested precision — and we've been putting Ohio's new postnup statute to work since it arrived.

Straight answers.

Are postnups really legal in Ohio now?

Yes — since March 2023, by statute. Requirements are strict and the doctrine is young; this is not a DIY document.

Are Ohio prenups enforceable?

Yes, under well-settled Supreme Court standards — with spousal support terms tested again at enforcement.

Does living together create rights in Ohio?

Not for relationships formed after October 1991. Contracts, deeds, and estate documents are the only structure you'll have.

Do Ohio prenups need witnesses?

Ohio requires marital agreements to be executed with the formalities the statutes prescribe — and standard practice adds notarization and counsel acknowledgments regardless, because execution ceremony is the cheapest challenge-proofing available.

Should we update our pre-2023 Ohio prenup now that postnups are legal?

If circumstances have moved — a business grown, wealth arrived, provisions aged badly — yes, that's the new statute's highest use. A fresh postnup with current disclosure beats litigating a stale prenup's fairness a decade from now.

Can an Ohio agreement protect a family business across generations?

That's core use: classify the interest and its appreciation, fix valuation methodology, and coordinate with buy-sell agreements and the estate plan. In the active-appreciation state, the agreement is what keeps a divorce court out of the growth story.
