A Mississippi prenuptial agreement is a written contract two people sign before they marry. It records who owns what, how property and debt get divided if the marriage ends, and whether either spouse pays support. Mississippi law requires it to be in writing and signed by the spouse it is enforced against.[1]
How much does a prenup cost in Mississippi? Most couples pay $1,500 to $3,000 for a simple agreement, and more when a business or real estate is involved. A prenup cannot decide child custody or child support, and it cannot include conditions that break the law or public policy. The rules that apply in every state are set out in our general prenuptial agreement guide.

A prenuptial agreement, also called an antenuptial agreement, is a contract signed before the wedding that fixes ownership rights in advance. Mississippi is an equitable distribution state rather than a community property state, so without an agreement a judge divides marital assets in whatever way the judge considers fair. That is rarely an even split. A prenup lets the couple set those rules themselves.
Mississippi has not adopted the Uniform Premarital Agreement Act. Prenuptial agreements here run on ordinary contract law, with one extra requirement that courts describe as fairness in the execution.
Mississippi uses several names for the same contract. Prenups, prenuptial agreements, antenuptial agreements and premarital agreements all mean the same thing. The title at the top of your document does not change how a judge reads it.
Work through the agreement in the order a judge will later read it. Start early, put every asset and debt in writing, give each spouse time to read and negotiate, and complete it well before the wedding. Most challenges in Mississippi come from a rushed signature or from one spouse leaving something out of the financial disclosure.
Open with the full legal name of each spouse, the planned date of marriage, and a statement that both are signing freely. This part of the contract also names any children from an earlier relationship, because a prenup is often the place where an inheritance for them is protected.
The conditions each spouse puts forward are the substance of the agreement. Decide in advance how separate and marital property are classified. Set out how assets and debts are split in the event of divorce, and what happens on the death or disability of one spouse. Read what the other side proposes and either agree to it or say no before you commit.
The contract takes effect when the marriage is registered, so both signatures and the date have to be in place before the ceremony. Mississippi does not require notarization by statute, but a notarised signature is strongly recommended because it removes any later argument about whose signature is on the page.
Mississippi has not adopted the Uniform Premarital Agreement Act, so there is no premarital agreement statute to follow. Courts here treat prenuptial agreements as ordinary contracts and apply an extra fairness test drawn from Mississippi Supreme Court decisions. One statutory rule does apply directly: an agreement made in consideration of marriage must be in writing and signed by the party to be charged.[1]
unless, in each of said cases, the promise or agreement upon which such action may be brought, or some memorandum or note thereof, shall be in writing, and signed by the party to be charged therewith or signed by some person by him or her thereunto lawfully authorized in writing.
Two things make a Mississippi prenup valid on its face. It is in writing, and both spouses have signed it before the wedding. Everything else, notarization included, is evidence rather than a requirement.
Mississippi courts add a fairness in the execution test on top of the ordinary contract rules. It has two parts. The agreement must have been signed voluntarily, without coercion, undue influence or duress. And each spouse must have made full disclosure of their finances, or already have known what the other owned.
Whether a Mississippi judge will also review the fairness of the terms themselves is unsettled. The safe approach is an agreement that is both properly executed and reasonable in substance.
A Mississippi judge can set aside all or part of a prenuptial agreement. The usual grounds are a signature obtained by pressure, a financial disclosure that turns out to be incomplete, or provisions that stray into matters a private contract cannot settle. Mississippi courts have repeatedly rejected the argument that a spouse simply did not read the document before signing it.
A prenup can settle almost anything about money. It can classify each spouse's separate and marital property, and divide assets and debts on divorce or death. It can waive or limit alimony, protect an inheritance or a gift, and shield a business or a professional practice. What it cannot do is decide a matter that belongs to a judge, or one the law puts beyond private agreement.
The content of a Mississippi prenuptial agreement is yours to negotiate, and it can cover:
It cannot:
A Mississippi prenuptial agreement fails for one of four reasons. The signature was given under pressure. The financial disclosure left something out. The terms reach into matters a private contract cannot settle. Or the promise was never put in writing at all. The first two account for most challenges, and both are avoidable while the contract is still being drafted.
Handing your partner an agreement to sign in the week of the wedding is the most common reason these contracts get challenged. Mississippi courts look closely at timing when they judge whether a signature was voluntary.
Prenups are not void merely because one spouse later regrets the deal, or because the split now looks lopsided. Mississippi courts hold a party to a contract they signed. The state has also not settled whether a judge may review the fairness of the terms themselves at all.
Most couples in Mississippi pay between $1,500 and $3,000 for a straightforward prenuptial agreement. A moderate agreement with real estate and retirement accounts runs $3,000 to $5,000. A complex one with business interests or out-of-state property reaches $5,000 to $10,000. The hourly rate in the state runs roughly $200 to $500, and a flat fee quote is common for simple work.
| Complexity | Typical cost | What it fits |
|---|---|---|
| Simple | $1,500 to $3,000 | Salary income, no business, no children from an earlier relationship |
| Moderate | $3,000 to $5,000 | Real estate, retirement accounts, modest separate property |
| Complex | $5,000 to $10,000 | Business interests, property in more than one state, an expected inheritance |
Three things move the price:
Many Mississippi firms quote flat fee pricing for prenuptial agreements rather than billing by the hour, and a first consultation is often free or credited against the flat fee. Ask whether a quote is a flat fee or an hourly rate before work starts, and get the pricing in writing.
Prenups drafted from a free template cost nothing to start. Plenty of couples use one to draft a first version, then pay an attorney for a legal review before they commit.
No rule makes a lawyer compulsory, and Mississippi courts have enforced prenuptial agreements where one spouse chose not to use one. In Mabus v. Mabus, 890 So. 2d 806, the Mississippi Supreme Court held in 2003 that a prenuptial agreement is not automatically invalid because one party lacked independent counsel. The signing still had to be voluntary, and the disclosure adequate.
An attorney is still worth the cost in most situations. A lawyer who drafts these agreements will know how Mississippi applies the fairness in the execution standard. A separate review by each spouse's own attorney also removes the strongest argument a challenger has.
An attorney earns the fee when:
If only one of you retains counsel, say so in the document and make sure the other spouse has time to get advice on it. A short consultation with a Mississippi family law attorney will tell you whether your finances are simple enough to handle on your own.

Mississippi has no premarital agreement statute. Most of the rules set out above come from decisions of the Mississippi Supreme Court, and from what family law attorneys practising in the state publish. The one statutory rule that applies directly is the statute of frauds. The source cited below is the state's official edition of the Miss. Code Ann.
