Prenuptial Agreements in Missouri: What the Law Provides
If you are getting married in Missouri, the state already has a default set of rules for what happens to your property. A prenuptial agreement is simply the mechanism for writing your own terms instead of accepting those defaults. Here is what the law generally provides.

How Missouri divides property
Missouri follows equitable distribution. Rather than an automatic 50/50 split, a court divides marital property in a way it considers fair, weighing factors such as the length of the marriage, each spouse's income and earning capacity, contributions to the household (including non-financial ones), and the circumstances of each party. "Equitable" does not mean "equal," and the outcome is far less predictable than a written agreement.
What a prenuptial agreement can generally address in Missouri
Agreements commonly cover: classifying property as separate or marital; how appreciation on separate property is treated; responsibility for debts brought into the marriage; treatment of a business interest or professional practice; and terms around spousal support. Provisions concerning child custody or child support are generally not enforceable, because courts retain authority to decide those based on the child's best interests at the time.
What tends to make an agreement hold up
Across states, the recurring themes in enforceability are full and fair financial disclosure by both parties, adequate time to review before signing (signing on the eve of a wedding invites challenge), the absence of coercion, and independent legal representation for each spouse. An agreement drafted without independent counsel on both sides is materially easier to attack later.
