Missouri Divorce Finances: What You Need to Know

Missouri is an equitable distribution state — courts divide marital assets based on what they consider fair given the facts of the marriage, not automatically in half. Alimony is called "maintenance" and comes with a two-part eligibility test that many people don't know about. Child support uses a Form 14 worksheet that combines both parents' incomes and adjusts for child-related expenses. And like most states, retirement accounts built during the marriage are marital property subject to division.

This page explains how Missouri generally handles each of these areas in plain English. The links throughout connect to deeper guides on each topic.

Property Division: Equitable Distribution in Missouri

Missouri divides marital property under RSMo § 452.330. Equitable distribution means a judge divides marital assets in a way they consider just — based on the specific circumstances, not by a fixed formula. An equal split is common in many Missouri divorces, but judges have the discretion to arrive at a different outcome when the facts support it.

Before dividing anything, courts classify each asset as either marital or nonmarital property. Marital property generally includes everything acquired by either spouse during the marriage — real estate, bank accounts, retirement savings, investment accounts, vehicles, and business interests built during the marriage. It typically doesn't matter whose name is on the title; if it was acquired during the marriage, it's presumed marital. Nonmarital property — assets owned before the marriage, gifts received by one spouse individually, and inheritances — is generally set aside and not divided.

There's one area that catches people off guard: commingling. If you inherited money and deposited it into a joint checking account that both spouses used for everyday expenses, that inheritance may lose its separate character. Courts look at whether the separate asset remained identifiable and traceable. Good records from before the marriage can matter in these situations.

Missouri courts weigh several factors when dividing marital property. These include the economic circumstances of each spouse at the time of division; how each spouse contributed to acquiring, preserving, or depreciating the marital assets; the value of each spouse's nonmarital property; the conduct of each party during the marriage (including whether either spouse dissipated or wasted marital assets); and the custodial arrangements for any children. The length of the marriage and each spouse's earning capacity also factor into the analysis.

Maintenance: Missouri's Two-Part Eligibility Test

Missouri calls alimony "maintenance" and governs it under RSMo § 452.335. Before a court considers how much maintenance to award or for how long, the spouse requesting it has to clear a two-part threshold. Many people don't realize this hurdle exists.

To be eligible, the requesting spouse must show both of the following: first, that they lack sufficient property — including marital property assigned to them — to provide for their reasonable needs; and second, that they either cannot be self-supporting through appropriate employment, or they are the custodian of a child whose age or condition makes it appropriate for the custodian not to work outside the home. Both conditions must be met. If a spouse has enough assets from the property division to meet their needs, a court may not award maintenance regardless of the income gap between the spouses.

The 8 statutory factors courts weigh when setting maintenance include: the financial resources of the spouse seeking maintenance, including the marital property assigned to them and their ability to support themselves through employment; the time needed to acquire education or training for appropriate employment; the standard of living during the marriage; the length of the marriage; the age and physical and emotional condition of the spouse seeking maintenance; the ability of the other spouse to meet their own needs while paying maintenance; and any other relevant factors the court considers just and appropriate.

Missouri maintenance can be rehabilitative (time-limited, to help a spouse become self-sufficient) or longer-term when the circumstances call for it. Courts may also award maintenance as part of a negotiated settlement agreement, which can provide more predictability than leaving the decision entirely to judicial discretion.

Child Support: Form 14 and the Income Shares Model

Missouri calculates child support using Form 14 — the Presumed Child Support Amount worksheet — under Missouri Supreme Court Rule 88.01. The state uses an Income Shares Model: both parents' gross monthly incomes are combined, adjusted for specific expenses, and the resulting obligation is shared proportionally based on each parent's share of the total income.

Missouri defines gross income broadly for child support purposes. It typically includes wages, salary, self-employment income, bonuses, commissions, investment income, rental income, pension or retirement payments, and other regular income sources. The Form 14 calculation then adjusts for work-related child care costs and the cost of the child's health insurance premiums — these are added to the basic support obligation and split between the parents proportionally.

Parenting time can affect the child support calculation in Missouri. When a non-custodial parent has significant parenting time — generally defined as at least 36% of the overnights — a parenting time adjustment may apply, reducing the support amount to reflect the added expenses the non-custodial parent bears while the child is in their care. The adjustment is built into the Form 14 worksheet and is calculated based on the actual number of overnights.

Self-employed parents deserve special attention in Missouri child support cases. Courts may look past reported income to imputed income — an estimate of what a parent could earn if they were working full time at their demonstrated skill level — if there's reason to believe a parent is voluntarily underemployed or not reporting all income.

Retirement Accounts: QDROs and the Marital Share

Retirement accounts built during the marriage are marital property in Missouri and subject to equitable distribution. The portion that accrued before the marriage is generally nonmarital and stays with the account holder. Courts typically use a coverture fraction — months the account was funded during the marriage divided by total months the account was funded — to identify the marital share when the account pre-dates the marriage.

Dividing a 401(k), 403(b), or private pension typically requires a Qualified Domestic Relations Order (QDRO). A QDRO is a court order that instructs the retirement plan administrator to divide the account and transfer a specified portion to the other spouse. When properly structured, the transfer may be completed without triggering early withdrawal penalties or immediate income taxes. Without a proper QDRO, any early access to these funds could result in significant tax consequences.

IRA accounts require a different process. A transfer incident to divorce avoids immediate taxes when handled correctly, but the accounts need to be properly titled to the receiving spouse's IRA. Traditional IRAs and Roth IRAs have different tax characteristics, so the after-tax value of each isn't necessarily the same even if the balances match.

Military retirement benefits are also divisible in Missouri divorces under the Uniformed Services Former Spouses' Protection Act (USFSPA). Federal Thrift Savings Plan (TSP) accounts require a "Retirement Benefits Court Order" rather than a standard QDRO. If either spouse has federal government employment or military service, additional steps are required to handle those accounts properly.
