Everything engaged couples need to know about making a prenuptial agreement valid and enforceable in Mississippi — in plain English, reviewed by attorney James Sexton, Esq.
Yes — prenuptial agreements are legal in Mississippi and enforced like any other contract when fairly executed.
Mississippi has no premarital-agreement statute and never adopted the UPAA — prenups are governed by case law. The foundation is Smith v. Smith, 656 So. 2d 1143 (Miss. 1995), where the Mississippi Supreme Court held an antenuptial agreement is as enforceable as any other contract. Mabus v. Mabus, 890 So. 2d 806 (Miss. 2003), supplies the working standard: ordinary contract principles plus a heightened requirement that the agreement be fair in the execution — meaning voluntary, informed, and supported by fair financial disclosure. Divorce cases are heard by chancellors, Mississippi's equity judges, who decide enforceability.
A Mississippi prenup is enforceable when it was entered voluntarily and was fair in the execution — with each party disclosing their finances or already knowing the other's.
The agreement should be a written contract signed by both parties before the marriage. As with any significant contract, a signed writing is the baseline for enforcement in Mississippi.
Both parties must sign free of duress or coercion, understanding the agreement's terms. In Mabus, the court stressed that the wife understood the deal and signed to protect her own anticipated inheritance.
Each party must disclose their financial assets — either through disclosure statements exchanged with the agreement or through independent knowledge of each other's financial condition.
Beyond ordinary contract rules, Mississippi chancellors ask whether the process of making the agreement was fair: no hidden assets, no ambush, and a real chance to seek advice. Counsel isn't required, but the opportunity matters.

Mississippi chancellors set aside prenups that were signed involuntarily or were unfair in the execution — most often because assets were concealed or the agreement was sprung on a spouse without real disclosure.
Because Mississippi treats a prenup as an ordinary contract with a fairness overlay, the attack points are familiar: fraud, duress, concealment, and lack of disclosure. Mabus v. Mabus shows what survives — the agreement was enforced because the wife wanted it, understood it, knew she could hire her own attorney, and signed voluntarily. Chancellors have broad equitable discretion, so a clean process is everything: exchange financial statements, sign well before the wedding, and give each side a genuine chance to get advice.

No — Mississippi has no statute requiring notarization of prenuptial agreements. It's still strongly recommended as proof the signatures are genuine, and it's available as an add-on.
Yes — a spouse can argue it was signed involuntarily or wasn't fair in the execution, typically pointing to concealed assets or missing disclosure. An agreement with exchanged financial statements and an unpressured signing is hard to unwind.
No. Mississippi has no premarital-agreement statute and hasn't adopted the UPAA. Prenups are governed entirely by case law — chiefly Smith v. Smith (1995), which made them enforceable like ordinary contracts, and Mabus v. Mabus (2003), which set the fairness standard.
No — in Mabus v. Mabus, the agreement was enforced even though the wife knew she could hire her own attorney and chose not to. What matters is the genuine opportunity. Trusted Prenup offers an optional attorney-review add-on for couples who want it.
Yes. Mississippi courts, including in Mabus, have enforced prenups that address alimony. As with the rest of the agreement, the provision must be voluntary and fair in the execution.
