Prenuptial Agreement Requirements in Alabama

At a glance

Requirements one by one

Alabama uses statutes plus the Allison/Barnhill test

Alabama has not enacted a comprehensive premarital-agreement act. Ala. Code § 8-9-2 supplies the Statute of Frauds writing rule. Ala. Code § 30-4-9 makes spousal contracts subject to the law governing confidential relationships, and Brown cites that rule while explaining why courts closely examine antenuptial agreements. Section 43-8-72 separately governs waivers of a surviving spouse's statutory rights at death.

The controlling enforceability rule comes from Allison v. Stevens as stated in Barnhill v. Barnhill and reaffirmed by Brown. The party seeking enforcement must prove one of two alternative tests.

The agreement must express the marriage consideration in a signed writing

Section 8-9-2 makes an agreement based on consideration of marriage void unless the agreement, a note, or a memorandum expressing the consideration is written and subscribed by the party to be charged or that party's authorized signer. Because enforcement may run in both directions, both prospective spouses should sign. Barnhill and Lemaster hold that the marriage itself may supply sufficient consideration.

The statute does not contain a separate effective-on-marriage sentence. Its rule instead applies because the agreement is made upon consideration of the planned marriage.

Disclosure depends on the enforcement route and the rights being waived

Barnhill's second alternative requires knowledge of the party's interest in the other estate and its approximate value. Lemaster explains that general knowledge may satisfy that standard on the facts; exact net worth was not required there. Alabama has no statutory form by which a party simply waives that knowledge requirement.

A waiver of death rights has an additional statutory rule. Section 43-8-72 requires a written contract, agreement, or waiver signed by the waiving party after fair disclosure. That condition applies to elective-share, homestead- allowance, exempt-property, and family-allowance rights even if the agreement passes the general Barnhill test.

Independent advice belongs to Barnhill's second alternative

Brown emphasizes that the two Allison/Barnhill tests are separate. Competent independent advice is an element of the second route, together with voluntary execution and knowledge of the estate interest and approximate value. It is not an element stated in the first route, which instead requires adequate consideration and an entirely fair, just, and equitable transaction from the other party's point of view.

Neither the statutes nor these cases set a fixed review period or number of days before the wedding. Timing, pressure, and access to advice remain evidence in the fact-specific voluntariness and fairness inquiry.

The proponent may satisfy either fairness test

Under the first route, the proponent must prove adequate consideration and that the entire transaction was fair, just, and equitable from the other party's viewpoint. Under the second, the proponent must prove free and voluntary entry, competent independent advice, and full knowledge of the estate interest and its approximate value. Barnhill says satisfying either route is enough, and Brown reaffirmed that courts must not collapse them into one test.

A valid agreement may waive alimony and support

The agreement enforced in Barnhill barred claims for support and alimony. Brown likewise affirmed denial of alimony based on an enforceable antenuptial agreement. Alabama's governing provisions do not contain a UPAA-style public- assistance override; the support term instead stands or falls under the Allison/Barnhill framework.

Child support and custody remain under court control

Willis calls a parent's attempted exchange of visitation for release from child support a legal impossibility and says the child's support right cannot be waived by parental agreement. For custody, § 30-3-152 requires the court to consider joint custody but authorizes whatever custody form serves the child's best interests, including joint custody without both parents' consent.

Substantive changes should not be oral

Lemaster holds that an oral modification going to the substance of an agreement has no effect when the agreement falls within the Statute of Frauds and the death-right waiver must also be written. Harrison upheld a finding that the spouses had not mutually agreed to rescind their prenup. It expressly left open whether every postnuptial rescission must independently satisfy Barnhill.

What trips people up

• Notarization is not a universal Alabama prenup formality. The governing statutes and Allison/Barnhill cases do not require a notary, witnesses, acknowledgment, oath, or recording for every prenup. A notary block may help prove execution, but it should not be described as the statewide validity rule.
• Death-right waivers have their own disclosure condition. A prenup that addresses divorce property and support may also waive rights at death, but § 43-8-72 independently requires fair disclosure for that waiver.
• Unequal wealth alone is not the fairness test. Lemaster rejected invalidity based merely on disparity in net worth where the evidence otherwise satisfied the governing standard and showed no fraud, duress, or other culpable conduct.
• A rescission needs proof of mutual agreement. Harrison did not create a complete rescission formula; it affirmed because the claimed mutual decision to void the agreement was not proved.

Common questions

Can an authorized representative sign the memorandum?

Section 8-9-2 permits subscription by another person only when the party to be charged has lawfully authorized that signer in writing.

What does a waiver of “all rights” cover at death?

Unless the document says otherwise, § 43-8-72 treats that language as waiving the elective share, homestead allowance, exempt property, family allowance, intestate benefits, and benefits under a will signed before the waiver.

What if the agreement promises an additional benefit that is not delivered?

Lemaster distinguished validity from performance. It held the antenuptial agreement valid but remanded for the trial court to decide whether failure to provide promised housing and a vehicle supported a contract-damages claim.
