Missouri starts custody from a joint-parenting presumption.

Missouri is a no-fault state, and our record has a 30-day waiting period for it. Its defining feature is custody. Under RSMo 452.375, courts begin from a presumption that joint physical and legal custody serves the child's best interest, which limits judicial discretion compared with states that weigh custody from scratch. Missouri divides marital property under equitable distribution and uses the Income Shares model for child support. Attorney rates run $175 to $350 per hour, and a contested case runs $9,000 to $28,000.

What this section says about Missouri's parenting-time presumption and property system is a characterisation this site carries rather than a finding. That is our own record rather than Missouri's own law.

Key Fact

Under Missouri statute RSMo 452.375, courts start from a presumption favoring joint custody, making shared parenting the default starting point rather than the exception.

Recent Development

Missouri SB 35, effective August 28, 2023, created a rebuttable presumption that equal or approximately equal parenting time is in the best interest of the child (RSMo 452.375).

Where these Missouri figures come from, since it is fair to ask. The court filing fee is the one we have gone back to, and even there we are recording what a fee schedule says rather than citing a document we have opened. Everything else on this page that is a cost or a length of time - attorney rates, the mediator's per-session rate, QDRO preparation, the uncontested and contested totals, the number of months a case takes - came into our data when the site was first built, and nobody has checked any of it against a published source since. Our own value distributions give the game away: attorney rates across all fifty states take seven distinct values at the low end, every one of them a multiple of 25, which is what a set of estimates looks like rather than fifty separate readings. We think they are in the right neighbourhood. We are not going to call them Missouri averages. For a real number, a Missouri family law attorney will quote you their own rate, and the clerk of court in your county will tell you the filing fee to the dollar.

The waiting period and the residency requirement in that table are in the same position, and they matter more, because a wrong number there is a filing in the wrong place rather than a bad estimate. Both came into our data at the original build and nobody here has read Missouri's dissolution statute. Confirm both with the clerk of court in the county where you will file, and ask specifically whether the wait runs from the day you file or from a separation date, because states do it both ways and our records hold one number for both cases.

DCE State Score Breakdown

Our proprietary index ranks every state on cost, complexity, and timeline. Higher is more favorable.

Overall DCE State Score

75/ 100

On our own 0 to 100 scale, a score of 75 puts Missouri in the band we call favorable, which runs 70 and above. The cut points are ours, set when we built the score, and they compare Missouri with no average.

Cost Score

30/ 40

The midpoint of the uncontested cost range we hold for Missouri, against a national baseline of ours. A higher cost lowers the score.

Complexity Score

30/ 30

Lowered by a longer waiting period, a longer residency requirement, a mediation requirement, a discretionary approach to alimony and more judicial discretion over custody, and raised by an equal-parenting presumption and collaborative divorce being available, each as we hold it for Missouri.

Timeline Score

15/ 30

Based on our own contested duration estimate for Missouri and the uncontested duration our pages show for it, which is never below its waiting period, each against a national baseline of ours. A longer case lowers the score.

Missouri Divorce Laws Overview

Property Division

Our record has Missouri as an equitable distribution state. That is our own record rather than Missouri's own property division law. Equitable does not mean equal, it means fair, based on the circumstances. Judges consider factors including each spouse's income and earning capacity, contributions to the marriage, length of the marriage, and the economic circumstances of each spouse. Outcomes can vary significantly from case to case.

Spousal Support (Alimony)

Missouri judges have broad discretion in setting alimony awards, and our record carries no statutory formula for the state. The factors it lists are: length of the marriage, standard of living during the marriage, each spouse's earning capacity, financial resources of each spouse, marital fault. Those came into our data at the original build rather than from a reading of the statute. The exception is marital fault, which was added to that list from a reading of RSMo § 452.335.2(9), which names it among the factors the court weighs. Some of Missouri's own law has been opened here - RSMo § 452.335.1 (read from an Internet Archive capture of revisor.mo.gov dated 2026-07-11) - and that reading covers the threshold in RSMo § 452.335.1 and not how a Missouri court weighs the factors in subsection 2, and this calculator collects neither the property nor the earning capacity the threshold turns on, so it settles neither the factor list nor the absence of a formula. Outcomes can vary significantly depending on the judge and the specific facts of your case.

Child Support

Our record puts Missouri among the Income Shares Model states, and nobody here has read Missouri's own guideline to check it. In that model both parents' incomes are combined, a total support obligation is set from that combined figure and the number of children, and each parent's share is proportional to their share of the combined income. The paying parent pays their share to the receiving parent.

Custody and Parenting Time

Our record puts Missouri among the states presuming equal parenting time (50/50) as the default starting point, where a court needs a documented reason such as domestic violence, substance abuse or evidence of harm to depart from it. That is our own record rather than Missouri's own custody law. Where it holds, it makes custody outcomes more predictable than in a state that leaves the question to the judge.

Missouri Adopts Equal Parenting Time Presumption

Major

Our record dates this to August 2023

Missouri custody cases now begin from a 50/50 baseline. A parent opposing equal time must rebut the presumption with specific evidence, such as documented domestic violence or an agreed parenting schedule.

The link goes to the legislature's page for the bill rather than to the enacted text. A bill page carries the same title, synopsis and effective date whether the bill passed or died, so it is not on its own evidence that this became law.

Frequently Asked Questions

How much does a divorce cost in Missouri?
Our working estimate is $1,200 - $3,500 for an uncontested Missouri divorce and $9,000 - $28,000 for a contested one, with the spread depending on attorney involvement, custody disputes, and the complexity of the marital estate. Court filing fees alone are $163 - $201. Both totals are ours rather than measured averages: they came into our data when this site was built and no survey stands behind them.
How long does a divorce take in Missouri?
Our records put Missouri's mandatory wait at 30 days, an uncontested case at roughly 3 months, and a contested one at about 10. Treat all three as ours rather than as findings: we have not read Missouri's dissolution statute or its court caseload statistics. The clerk of court in the county where you will file can confirm the wait, and whether it runs from filing or from a separation date, which differs by state.
