Missouri has not adopted the Uniform Premarital Agreement Act. Unlike most states, Missouri does not have a statute that governs the validity of prenuptial agreements. Instead, the rules come entirely from Missouri court decisions, which have developed a clear two-part standard over the years.
Missouri is an equitable distribution state, not a community property state. Without a prenuptial agreement, a court divides marital property in a way it considers fair, which is not the same as an even split and depends on the court’s assessment of the circumstances. A prenuptial agreement lets you decide these terms in advance rather than leaving them to a judge.
To be enforceable in Missouri, a prenuptial agreement must satisfy two separate requirements:
Both requirements must be met. An agreement that was signed voluntarily but is grossly one-sided can fail, and so can a fair-looking agreement that was signed without proper disclosure.
There is an important timing point. Missouri evaluates conscionability as of the date the agreement was signed, not at the time of divorce. That is different from a few states that re-examine fairness years later based on changed circumstances. In Missouri, what matters is whether the agreement was fair and properly made when it was signed. Because of that, anyone signing a Missouri prenup should think carefully about whether its terms still protect them if their circumstances change, since the agreement is judged by the moment it was made.
To be valid, the agreement must be in writing and signed. Oral agreements are not enforceable. Notarization or witnessing is strongly recommended, as is independent counsel for each party. Missouri courts look closely at whether both parties had their own lawyer and whether there was enough time before the wedding to review and revise the agreement, since a last-minute signing can suggest duress.
Missouri requires two things, and both have to hold: the agreement must have been made fairly and with full financial disclosure, and the terms themselves must be conscionable. Missouri also judges fairness as of the day you sign, not at divorce. That means full, documented disclosure and genuinely fair terms are both essential, and it means you should make sure the agreement still protects you if your situation changes, because the court looks at the moment it was signed. We draft for both halves of that standard.

I spent years helping couples navigate divorce. The financial damage I saw was not inevitable. Assets split under laws couples never understood, decades of work undone. Most of it could have been addressed clearly and fairly before the wedding with a well-crafted prenuptial agreement. I built Prenups.com to make that process accessible for any couple that wants to start their marriage on the same page, financially and legally.

A prenuptial agreement in Missouri, also called an antenuptial or premarital agreement, is a written contract signed before marriage that sets out how a couple’s property, debts, and spousal maintenance will be handled if the marriage ends in divorce or death. Missouri has no prenup statute, so these agreements are governed by Missouri case law, which requires both procedural fairness and conscionable terms.
Yes. Missouri enforces prenuptial agreements that meet its two-part standard. The agreement must have been entered into freely, fairly, knowingly, in good faith, and with full financial disclosure, and the terms must be conscionable, meaning not grossly one-sided. Missouri courts will set aside agreements that fail either part.
A valid Missouri prenup must be in writing and signed, entered into voluntarily with full financial disclosure, and conscionable in its terms. Notarization or witnessing is strongly recommended, as is independent counsel for each party. Oral agreements are not enforceable, and missing disclosure is one of the most common reasons an agreement fails.
At Prenups.com, a Missouri prenuptial agreement is a flat fee of $3,500. There is no hourly billing and no surprise charges. The fee includes drafting, all revisions and negotiation, and coordinated online signing. Postnuptial agreements are $4,500. Complex or high net worth matters are handled through our Platinum service starting at $10,000.
Most Missouri prenuptial agreements are completed in about two to three weeks from the initial consultation, depending on how quickly both parties review and respond. We recommend starting well before the wedding, because Missouri courts treat a last-minute signing as a sign of possible duress, which can undermine the agreement.
Yes. A prenuptial agreement must be signed before marriage and takes effect on the date of marriage. If you are already married, the equivalent document is a postnuptial agreement. Missouri does not set a fixed statutory waiting period, but enough time to review and revise before the wedding is important to show the agreement was made freely.
Yes. A Missouri prenup can be challenged if it was not entered into freely, fairly, and with full disclosure, or if its terms were unconscionable when signed. Missouri judges conscionability as of the date the agreement was signed, not at the time of divorce, so the focus is on whether the agreement was fair and properly made at that time.
A Missouri prenup can identify and protect separate property, divide property and assets on divorce or death, address debts, gifts, and inheritances, set spousal maintenance terms subject to the conscionability standard, protect a business, and include estate planning provisions, including protection for children from prior relationships.
A Missouri prenup cannot determine child support, custody, or visitation, which the court decides based on the child’s best interests. It also cannot be enforced if it was not made freely and with full disclosure, or if its terms were unconscionable when signed, and it cannot include terms that violate public policy or law.
Missouri does not strictly require each party to have a separate attorney, but courts look closely at whether both parties had independent counsel. Separate representation is strong evidence that the agreement was entered into knowingly and voluntarily, which is part of Missouri’s procedural fairness requirement. We strongly recommend it.
Yes. A prenuptial agreement is one of the most effective ways to protect a business in Missouri. It can confirm that a business is separate property, address how growth in value during the marriage is treated, and prevent a spouse from acquiring a marital interest in the company. This is especially important for founders, partners, and professional practice owners.
Yes. Missouri recognizes postnuptial agreements, which are held to the same general standards as prenups: they must be in writing, entered into freely and with full disclosure, and conscionable in their terms. At Prenups.com, a Missouri postnuptial agreement is a flat fee of $4,500.
