Prenups in Missouri - Frequently Asked Questions
Are prenuptial agreements enforceable in Missouri?
Yes. Prenups are enforceable in Missouri when the basic procedural requirements are met: voluntary signing, full and fair financial disclosure, independent counsel for both parties (or a knowing waiver), and terms that are not unconscionable. As an equitable distribution state, Missouri courts retain some discretion to set aside provisions that become unconscionable at enforcement.
What can a prenup cover in Missouri?
In Missouri, a prenup can address property division, alimony (waiver, cap, or duration limits), debt allocation, business interests, inheritance protection, and how to handle a future home purchase. Prenups cannot dictate child custody or child support; those are reserved for the court to decide based on the child's best interests at the time of divorce.
How much does a prenup cost in Missouri?
Prenups in Missouri typically cost $1,500 to $5,000 total when both parties retain their own counsel. Higher-net-worth or complex agreements (business interests, multiple jurisdictions, trust planning) can run $5,000 to $25,000 or more. Skipping independent counsel saves money up front but is the single most common reason prenups are challenged later.
Can we do a postnuptial agreement instead in Missouri?
Yes, Missouri allows postnuptial agreements (postnups) signed during the marriage. Postnups address the same topics as prenups, but courts review them more strictly because the parties are already legally bound to each other. Independent counsel and full disclosure are even more important for a postnup to hold up.
How do Missouri courts evaluate a prenup?
Missouri courts ask: Was the agreement voluntary? Was there full financial disclosure? Did each party have or knowingly waive independent counsel? Are the terms unconscionable now? Is anything in it about children that the court must override? If the answer to all the procedural questions is yes and the substantive terms are not unconscionable, the prenup will generally be enforced as written.
