Missouri starts custody from a joint-parenting presumption and keeps divorce costs moderate.

Missouri is a no-fault state with a relatively short 30-day waiting period, one of the quicker timelines for couples who agree on terms. 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 typically falls between $9,000 and $28,000.

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

Effective August 28, 2023, Missouri SB 35 created a rebuttable presumption that equal or approximately equal parenting time serves the child's best interest. Missouri custody cases now begin from a 50/50 baseline that a parent must rebut with specific evidence, such as documented domestic violence or an agreed parenting schedule.

Missouri Divorce Laws Overview

Property Division

Missouri uses equitable distribution to divide marital property. This 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. There is no statutory formula. Courts weigh a set of statutory factors including: length of the marriage, standard of living during the marriage, each spouse's earning capacity, financial resources of each spouse. This means outcomes can vary significantly depending on the judge and the specific facts of your case.

Child Support

Missouri uses the Income Shares Model for child support. Both parents' gross incomes are combined, the total support obligation is determined from a guideline table, 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

Missouri presumes equal parenting time (50/50) as the default starting point. Courts must have a documented reason, such as domestic violence, substance abuse, or evidence of harm, to deviate from this presumption. This makes Missouri more predictable for custody outcomes than states with full judicial discretion.
