Missouri's dissolution of marriage (divorce) law is governed by RSMo § 452.300 et seq., which Missouri adopted through the Dissolution of Marriage Act. Missouri is a no-fault divorce state — the only required ground for dissolution is "irretrievable breakdown of the marriage" (RSMo § 452.320). Missouri eliminated fault-based divorce grounds as a basis for the dissolution itself, but — importantly — fault can still be considered in the context of maintenance (alimony) determinations and property division to a limited degree in Missouri courts. Missouri's family law courts are organized through the circuit courts with family court divisions; Jackson County (Kansas City) and St. Louis County have busy family court dockets reflecting the population density and divorce rates of Missouri's two major metropolitan areas.

Missouri's property division standard is equitable distribution (RSMo § 452.330) — courts divide marital property in a manner the court deems "just" based on multiple statutory factors, not necessarily 50/50. Missouri distinguishes sharply between marital property (subject to division) and separate property (kept by the owning spouse). Marital property includes all property acquired during the marriage by either spouse, regardless of how title is held. Separate property includes property owned before the marriage, property received by gift or inheritance during the marriage, and property exchanged for separate property. However, Missouri's "commingling" doctrine — where separate and marital property become so intermingled that separate property can no longer be traced — can convert separate property to marital property. The classic Missouri commingling issue: a spouse who brought $50,000 in pre-marital savings to the marriage and deposited it into a joint bank account used for all marital expenses — after years of commingling, the original separate property may be unrecoverable as a separate property claim.

Military Families in Missouri: Fort Leonard Wood and Whiteman AFB

Missouri hosts Fort Leonard Wood in Pulaski County (a major Army training installation), Whiteman Air Force Base in Johnson County (home of B-2 Spirit stealth bomber fleet), Scott Air Force Base (just across the Illinois border in St. Clair County, with significant Missouri servicemember families). Military divorce in Missouri involves the Uniformed Services Former Spouses' Protection Act (USFSPA), which allows Missouri courts to divide military retirement pay as marital property in dissolution proceedings. Under USFSPA, Missouri courts can divide military retired pay earned during the overlap of the marriage and military service — the "coverture fraction" or "time rule" calculating the marital share. Missouri's military divorce practitioners are concentrated near Fort Leonard Wood (Waynesville/Rolla) and in the Kansas City area near Whiteman AFB (Warrensburg, Sedalia).
