Death Was Never the Deal

A.M. v. J.M., 2026-Ohio-2532 (8th Dist.), decided July 2, 2026, Case Nos. 114462 and 114488

An antenuptial agreement is a contract, and a contract procured by one side's silent edit can be reformed. In A.M. v. J.M., 2026-Ohio-2532 (8th Dist.), the court affirmed reformation of a prenup that Husband's counsel drafted to pay Wife her $3 million plus a share of net assets at Husband's death, after the negotiation emails confirmed payment on divorce. Nobody flagged the change for Wife's counsel. The trial court rewrote the payment trigger to match the bargain, and the Eighth District affirmed.

The legal hook is unilateral mistake plus knowledge. Reformation ordinarily requires a mutual mistake, but Ohio courts will reform an instrument where one party is mistaken and the other knows it and takes advantage. The panel found clear and convincing evidence on both prongs and rejected the argument that reformation requires an ambiguous document. The agreement was clear. It was clearly wrong.

The money followed. The court affirmed a $10,048,372 property-division payment built on Husband's own exhibits, spousal support covering household expenses until that payment is made in full, $8,000 per month in child support under R.C. 3119.04's above-guidelines framework, and contempt for $250,000 in unpaid interim attorney fees. Waiver ran through the opinion; arguments Husband left out of his trial brief were gone on appeal.

Two footnotes for court-watchers. The entire panel sat by assignment from the Ninth District, and both non-authoring judges concurred in judgment only, without opinion. A judgment-only concurrence on a reformation holding this significant leaves the doctrine a little softer than the syllabus suggests.

Practice point: preserve the negotiation file. The emails confirming the intended payment trigger decided this case, and the drafting lawyer's silence supplied the knowledge element. Draft the prenup, then read it against the correspondence line by line before anyone signs.
