Quick answer: Missouri divides marital property, which is property acquired after the marriage and before a decree of legal separation or dissolution with listed exceptions, in such proportions as the court deems just. The statute names no pension formula, and a qualified domestic relations order can be modified only to keep it qualified or to carry out its intent.
This Missouri pension division calculator shows the marital fraction of a benefit and an illustrative share under RSMo 452.330. You supply the months of service during the marriage, the total months, the monthly benefit and the share you want to test: the statute sets no percentage, so the share is your assumption.
Missouri pension and retirement division at a glance
| Rule | What Missouri says |
|---|---|
| Marital property | All property acquired by either spouse after the marriage, except gifts, bequests, devises and descent, exchanges for such property, property acquired after a decree of legal separation, property excluded by valid written agreement and certain increases in the value of nonmarital property (RSMo 452.330.2) |
| Presumption | Property acquired after the marriage and before a decree of legal separation or dissolution is presumed marital regardless of title (452.330.3) |
| Commingling | Nonmarital property does not become marital solely because it is commingled with marital property (452.330.4) |
| Division | Such proportions as the court deems just, considering economic circumstances, contributions including as a homemaker, the value of nonmarital property set apart, conduct during the marriage and custodial arrangements (452.330.1) |
| Finality | The property order is final and not modifiable, except qualified domestic relations orders for pension, profit sharing and stock bonus plans, which are modifiable only to establish or maintain them or to carry out their intent (452.330.5) |
| Military pay | Federal law caps total court-ordered payments at 50% of disposable retired pay and allows direct payment only after a 10-year marriage and service overlap (10 U.S.C. 1408) |

What does this pension division calculator check?
The calculator divides months of service during the marriage by total months of service, applies that fraction to the monthly benefit, and multiplies by the share you enter. The part outside the fraction, such as service before the marriage, is shown separately. For military retired pay it also checks the federal 10-year overlap that allows direct payment (10 U.S.C. 1408(d)(2)). A court may use a different method, and the benefit also depends on the plan’s own rules. To see the rest of the property split, use the Missouri property division calculator.
Frequently asked questions
Are pensions divided in a Missouri divorce?

Is premarital retirement divided in Missouri?
Property acquired before the marriage is nonmarital, though marital labor or funds that increased its value can create a marital part.

Only a qualified domestic relations order, and only to keep it qualified or to carry out its expressed intent.
