Key takeaways

  • Prenups are legal and enforceable in Kentucky under case law — the Kentucky Supreme Court's 1990 decisions in Edwardson v. Edwardson and Gentry v. Gentry.
  • Kentucky has NOT adopted the Uniform Premarital Agreement Act; there is no prenup statute, only judge-made rules plus KRS 371.010(5)'s writing requirement.
  • Kentucky courts take a "second look": a prenup must not be unconscionable at the time of enforcement, not just when it was signed.
  • Full financial disclosure and a voluntary, pressure-free signing are non-negotiable under the Gentry test.
  • Maintenance can be addressed or waived, but the waiver is reviewed again at divorce for unconscionability (Lane v. Lane).

Are prenups legal in Kentucky?

Yes — prenuptial agreements are legal and enforceable in Kentucky under the Kentucky Supreme Court's decisions in Edwardson v. Edwardson and Gentry v. Gentry.

Kentucky is one of the minority of states with no premarital-agreement statute — it never adopted the Uniform Premarital Agreement Act. Modern enforceability dates to 1990, when the Kentucky Supreme Court decided Gentry v. Gentry, 798 S.W.2d 928, and Edwardson v. Edwardson, 798 S.W.2d 941, sweeping away the old rule that prenups contemplating divorce were void. The agreement must be in writing under KRS 371.010(5), Kentucky's statute of frauds for promises made in consideration of marriage, and it must satisfy the court-made fairness tests both when signed and when enforced.

What makes a prenup enforceable in Kentucky?

A Kentucky prenup is enforceable when it was signed voluntarily with full disclosure and is not unconscionable — judged both at signing and again at the time of enforcement.

In writing

KRS 371.010(5) requires any agreement made in consideration of marriage to be in writing and signed. Oral prenups are unenforceable in Kentucky.

Full financial disclosure

Edwardson requires full disclosure of each party's assets, debts, and income before signing. Concealment or material misrepresentation is a classic basis for setting a Kentucky prenup aside.

Free of fraud, duress, or mistake

The first prong of the Gentry test asks whether the agreement was obtained through fraud, duress, or mistake. Signing well before the wedding, with time to get advice, is the practical answer.

Conscionable at signing AND at enforcement

Kentucky's distinctive rule: courts review the agreement again at divorce to make sure changed circumstances haven't made enforcement unconscionable. Terms that are reasonable, not punitive, survive that second look.

What you can & can't include

You can include

  • Which assets remain non-marital vs. marital property
  • How property acquired during the marriage is divided
  • Responsibility for premarital and marital debt
  • Maintenance (spousal support) terms or waivers

  • Estate rights and provisions on death

You can't include

  • Child custody or parenting time
  • Child support obligations
  • Terms that are unconscionable or violate public policy
  • Penalties or incentives around divorce or personal conduct

How Kentucky courts evaluate enforcement

Kentucky courts apply the three-prong Gentry test — fraud or duress, unconscionability, and materially changed circumstances — and will decline to enforce a prenup that fails any prong at the time of divorce.

The second look is what makes Kentucky different. Even a prenup that was perfectly fair on the wedding day can be refused enforcement if, by the time of divorce, circumstances have changed so dramatically that holding a spouse to it would be unconscionable — Lane v. Lane, 202 S.W.3d 577 (Ky. 2006), did exactly that with a maintenance waiver after a long marriage. The defense is drafting terms that stay reasonable over time, disclosing everything, and signing without pressure. Kentucky courts routinely enforce agreements built that way.

Kentucky prenup FAQ

How much does a prenup cost in Kentucky?

Attorney-drafted prenups in Kentucky typically run $1,500–$5,000 or more. Trusted Prenup creates a state-specific Kentucky prenup online for a flat $599, with optional notarization and attorney-review add-ons.

Does a Kentucky prenup need to be notarized?

No — Kentucky law requires only a written, signed agreement under KRS 371.010(5). Notarization is still wise as proof of who signed and when, and it's available as an add-on.

Can a prenup be challenged in Kentucky?

Yes, on three grounds from the Gentry test: fraud, duress, or mistake in obtaining it; unconscionability; or changed circumstances that make enforcement unreasonable at divorce. Full disclosure and fair terms are the antidote to all three.

Does Kentucky follow the Uniform Premarital Agreement Act?

No. Kentucky is one of the minority of states that never adopted the UPAA, so prenups are governed by Supreme Court case law — chiefly Edwardson v. Edwardson and Gentry v. Gentry (1990) — rather than a statute.

What is Kentucky's second-look rule?

Kentucky courts review a prenup twice: it must not be unconscionable when signed, and it must still not be unconscionable when enforcement is sought at divorce. A waiver that leaves one spouse in hardship after a long marriage can be set aside even if it was fair on the wedding day.

Can maintenance be waived in a Kentucky prenup?

Yes, couples can limit or waive maintenance — but under Lane v. Lane, that waiver gets re-examined at divorce and won't be enforced if changed circumstances have made it unconscionable. Reasonable, non-punitive terms are what survive.

Is an online prenup valid in Kentucky?

Yes — Kentucky enforces properly executed prenuptial agreements regardless of how they were drafted. What matters is execution: a written agreement, voluntary signatures, full financial disclosure, and Kentucky's signing formalities. The full picture is in are online prenups legally binding.
