Overview
Missouri is an equitable distribution state, meaning that courts divide marital property in a just manner considering all relevant circumstances at divorce. Missouri courts consider factors including the economic contributions of each spouse, the value of nonmarital property set aside for each, the parties’ debts and liabilities, and the economic circumstances of each party. Missouri adopted the Uniform Premarital Agreement Act, giving couples a clear statutory basis for enforceable prenups.
What Counts as Marital Property?
Marital property in Missouri includes all property acquired by either spouse during the marriage, regardless of how title is held, except property acquired by gift or inheritance. This includes wages, real estate, retirement benefits earned during the marriage, and the increase in value of marital property from marital effort or funds. Missouri courts apply a presumption that property acquired during the marriage is marital property.
What Stays Separate?
Nonmarital property in Missouri includes property owned before the marriage, gifts and bequests received individually, property excluded by a valid prenuptial agreement, and property acquired in exchange for nonmarital property. Appreciation of nonmarital property through purely passive market forces generally remains nonmarital. Missouri courts require clear and convincing evidence to establish nonmarital character when challenged.
Prenuptial Agreements in Missouri
Missouri adopted the Uniform Premarital Agreement Act at Missouri Revised Statutes § 459.010–459.060. A prenup must be in writing, signed by both parties before the marriage. It will not be enforced if involuntary, unconscionable at execution combined with inadequate disclosure, or obtained by fraud or duress. Missouri courts apply UPAA standards consistently, making the state’s prenup law clear and predictable.
Key Considerations
- Missouri courts presume all assets acquired during marriage are marital property — the burden of proving nonmarital character falls on the claiming spouse.
- Commingling separate and marital funds can extinguish the separate character of an asset, making documentation and separate accounts critical.
- Missouri does not recognize common-law marriage formed within the state, though it honors valid common-law marriages from other states.
- A prenup can address both property division and maintenance (alimony) in Missouri, providing comprehensive financial planning for both spouses.
Key Statutes
- Missouri Revised Statutes § 452.330 (equitable distribution of marital property)
