Are prenuptial agreements enforceable in Alabama?

Federal & State Law Editorial TeamLast reviewed: 2026-05-17

Alabama applies a long-standing common-law test that places the burden on the proponent to prove fairness or disclosure.

1. Governing Statute / Common Law

Alabama has no general prenup statute. The controlling decisions are Barnhill v. Barnhill, 386 So. 2d 749 (Ala. 1980) and Tibbs v. Anderson, 580 So. 2d 1308 (Ala. 1991). Ala. Code § 30-4-9 (general spousal contract authority) provides statutory backdrop.

2. Formality Requirements

The agreement must be in writing and signed by both parties. Acknowledgment and witnesses are best practice; agreements affecting real property must comply with the Statute of Frauds.

3. Voluntariness

Per Barnhill, the proponent must prove the spouse against whom enforcement is sought entered the agreement freely and voluntarily, with competent independent advice and full knowledge of her interest in the estate and its approximate value.

4. Disclosure

The proponent must prove EITHER: (a) the consideration was adequate and the entire transaction was fair, just, and equitable from the other party's point of view, OR (b) the agreement was freely and voluntarily entered into with competent independent advice and full knowledge of the other party's estate and approximate value. Tibbs clarifies this is an either/or test favorable to enforcement when disclosure is robust.

5. Unconscionability

Substantive fairness is part of prong (a) of the Barnhill test. The agreement is reviewed at execution; Alabama does not apply a "second look" at enforcement for property provisions.

6. What Cannot Be Waived

Child support and custody cannot be predetermined. Alimony waivers are generally enforceable if Barnhill is satisfied.

7. Key Alabama Case Law

Barnhill v. Barnhill (1980); Tibbs v. Anderson (1991); Strait v. Strait, 686 So. 2d 1230 (Ala. Civ. App. 1996).
