Missouri Divorce Timeline Estimator

An uncontested dissolution of marriage in Missouri typically takes 60–90 days, while contested cases average 6–12 months and can extend to 24 months if the case goes to trial. Missouri law under RSMo § 452.305 requires a minimum 30-day waiting period after filing before any divorce can be finalized. Court scheduling, discovery disputes, and the complexity of property division or child custody issues are the primary factors that extend the timeline.

Missouri imposes a mandatory 30-day waiting period under RSMo § 452.305 from the date the petition for dissolution of marriage is filed before a judge can issue a final decree. This cooling-off period applies to every divorce regardless of whether it is contested or uncontested. Missouri's 30-day requirement is one of the shortest mandatory waiting periods in the United States — many states require 60–90 days or longer.

Missouri does not require any period of separation before filing for dissolution of marriage. Unlike states such as North Carolina (1 year) or Virginia (1 year), Missouri allows either spouse to file immediately as long as the 90-day residency requirement under RSMo § 452.305 is satisfied. The only mandatory delay is the 30-day cooling-off period after the petition is filed with the circuit court.

An uncontested dissolution of marriage in Missouri typically finalizes in 60–90 days from the date of filing, though some streamlined cases complete in as few as 30–45 days. Both spouses must agree on all terms including property division, child custody, and support before the court hearing. The median cost for an uncontested Missouri divorce is approximately $3,000 as of 2022, compared to $10,000 for contested cases.

The fastest path to dissolution of marriage in Missouri is an uncontested filing where both spouses agree on all terms and the respondent signs an Entry of Appearance and Waiver of Service, eliminating the need for formal service of process. This approach can result in finalization in approximately 30–45 days — the absolute minimum allowed by the RSMo § 452.305 waiting period. Filing fees range from $150 to $225 depending on the county.

The respondent has 30 days after being served with the petition for dissolution of marriage to file a written Answer with the Missouri circuit court. If no Answer is filed within that 30-day window, the respondent is considered in default, and any allegations in the petition may be deemed admitted under Missouri court rules. The petitioner can then request a default judgment, which may accelerate the final decree.

Missouri requires all parents of minor children in a dissolution of marriage case to complete a court-approved parenting education program under RSMo § 452.600. Common approved programs include COPE (Co-Parent Education), a 2-hour class, and Focus on Kids, a program offered through MU Extension. The specific program and format — online or in-person — depends on the county where your case is filed, so check with your local circuit court.

A contested dissolution of marriage in Missouri typically takes 6–12 months, with complex cases involving trial extending to 12–24 months. The process includes a 30-day response period, formal discovery (interrogatories, depositions, subpoenas), possible court-ordered mediation under RSMo § 452.350, and trial scheduling. Contested Missouri divorces average $10,000 in total costs, with attorneys charging a median rate of $280 per hour as of 2022.
