To file for divorce in Missouri in 2026, at least one spouse must have lived in the state for 90 days immediately before filing the petition, under Mo. Rev. Stat. § 452.305. The court cannot finalize the divorce until 30 days have passed since filing. Filing fees range from $102.50 to $233.50 by county.
Missouri calls divorce a "dissolution of marriage," and the 90-day residency requirement is jurisdictional, meaning a court has no legal authority to grant your divorce unless this threshold is met. Only one of the two spouses needs to satisfy the divorce residency requirements in Missouri. Military members stationed in Missouri also qualify, even if their legal domicile remains another state. This guide explains the domicile requirement, filing jurisdiction, the 30-day waiting period, and how long to live in state before divorce is permitted.

What Are the Divorce Residency Requirements in Missouri?
The divorce residency requirements in Missouri demand that at least one spouse reside in the state for 90 days immediately preceding the filing of the petition, under Mo. Rev. Stat. § 452.305. The court must also wait 30 days after filing before entering judgment. Only one spouse must meet the 90-day threshold.
Missouri's residency rule is comparatively short. Many states require six months (180 days) of residency before filing, so Missouri's 90-day standard is half that length. The statute provides that a court "shall enter a judgment of dissolution of marriage if the court finds that one of the parties has been a resident of this state, or is a member of the armed services who has been stationed in this state, for ninety days immediately preceding the commencement of the proceeding." This single-spouse rule means that if one party recently moved to Missouri 90 days ago, the couple may file there even if the other spouse lives in a different state. The 90 days must be continuous and must immediately precede the filing date.
How Long Must You Live in Missouri Before Filing for Divorce?
You must live in Missouri for 90 days before the court can grant a divorce, under Mo. Rev. Stat. § 452.305. You may technically file the petition earlier, but the court cannot enter a final judgment until the 90-day residency and 30-day waiting period are both satisfied. Only one spouse needs to meet the 90-day mark.
For people asking how long to live in state before divorce in Missouri, the practical answer is 90 continuous days of residency by at least one spouse. Because residency is jurisdictional, attorneys generally advise establishing the full 90 days before filing rather than filing prematurely and risking dismissal. A spouse who moved to Missouri 60 days ago would need to wait another 30 days before the residency clock is complete. If you file too early, the opposing party can challenge the court's jurisdiction, and the case may be dismissed. The cleanest approach is to confirm 90 days of Missouri residency, then file, then count 30 more days to the earliest possible judgment date.
What Counts as Residency and Domicile in Missouri?
Missouri residency for divorce means living in the state with the intent to remain, which establishes domicile under Mo. Rev. Stat. § 452.305. Domicile combines physical presence with the intention to make Missouri your permanent home. Military members stationed in Missouri satisfy residency regardless of their legal domicile in another state.
The domicile requirement distinguishes a true resident from a temporary visitor. A person who lives in Missouri while intending to return to another state may not satisfy the domicile standard, even after 90 days of physical presence. Courts examine evidence such as a Missouri driver's license, voter registration, vehicle registration, a lease or property ownership, employment in the state, and where you pay state income taxes. The military exception in Mo. Rev. Stat. § 452.305 is significant: service members stationed at bases such as Fort Leonard Wood or Whiteman Air Force Base count as Missouri residents for divorce purposes even though they typically keep legal residence in their home state. This provision lets military families resolve marital matters in the state where they are physically assigned.
In Which Missouri County Should You File for Divorce?
Missouri imposes no separate county residency requirement, so you may file your dissolution petition in any county where either spouse resides under Mo. Rev. Stat. § 452.300. Cases are filed in the circuit court of the chosen county. The 90-day residency requirement applies to the state as a whole, not to any single county.
Filing jurisdiction in Missouri is flexible compared with many states. Because there is no minimum county residency period, a spouse who just moved across county lines can still file in the new county of residence, provided the statewide 90-day residency is met. In practice, most filers choose the county where they live or where the marital home is located, which keeps hearings and document service convenient. If the spouses live in different Missouri counties, either county is a proper venue. The case proceeds in the circuit court, which is Missouri's trial-level court that handles all dissolution of marriage actions across the state's 46 judicial circuits. Choosing the correct venue at the outset avoids transfer motions and delays later in the case.
How Much Does It Cost to File for Divorce in Missouri?
The filing fee for divorce in Missouri ranges from $102.50 to $233.50, depending on the county and whether minor children are involved. As of June 2026, St. Louis County charges $149, St. Charles County charges $133, Jackson County charges $177.50, and Cass County charges $163.50. Verify the exact amount with your local circuit clerk.
Filing fees vary across Missouri's 46 judicial circuits because each county sets its own court costs. A consistent pattern is that cases involving minor children cost $75 to $100 more than cases without children, due to additional administrative requirements. For example, Jefferson County charges $131 without minor children and $231 with minor children. Beyond the base filing fee, filers should budget for service of process ($25 to $75 for sheriff service, or $50 to $200 for a private process server), parenting education classes when children are involved ($25 to $75), and certified copies of the final decree ($5 to $15 each). These cost figures are accurate as of June 2026. Verify with your local clerk before filing, because court costs change periodically.
Cost Comparison: Missouri Divorce Filing Fees by County
| County | Filing Fee | Notes |
|---|---|---|
| St. Charles County | $133 | Dissolution of marriage |
| St. Louis County | $149 | Dissolution of marriage |
| Jefferson County | $131 (no children) / $231 (with children) | Children add roughly $100 |
| Cass County | $163.50 | Dissolution of marriage |
| Jackson County | $177.50 | Dissolution of marriage |
| Jasper County | $127.50 + $45 service | Service fee charged separately |
Figures above are as of June 2026. Verify with your local circuit clerk, because Missouri counties update their fee schedules periodically.
What If You Cannot Afford the Missouri Filing Fee?
Missouri courts waive divorce filing fees for filers who demonstrate financial hardship through an In Forma Pauperis application under Missouri court rules. You must file a Motion and Affidavit in Support of Request to Proceed as a Poor Person, detailing your monthly income, expenses, and assets. Courts typically approve waivers for applicants at or below 125% of the federal poverty level.
The fee waiver process exists so that the residency and filing rules do not bar low-income residents from accessing divorce. Courts routinely grant waivers to individuals receiving government assistance such as SNAP, TANF, or Medicaid, and to those whose household income falls at or below 125% of the federal poverty guideline. The affidavit must be truthful and complete; misstating finances can result in denial. Self-represented filers can obtain the standardized fee waiver forms and dissolution petitions free of charge at the Missouri Courts self-representation website. Even with a waiver, you must still satisfy the 90-day residency requirement and the 30-day waiting period, because those are jurisdictional standards that a fee waiver does not change.
What Is the Waiting Period After Filing for Divorce in Missouri?
Missouri imposes a mandatory 30-day waiting period between filing the petition and the earliest date a court may enter a judgment of dissolution, under Mo. Rev. Stat. § 452.305. This "cooling-off" period is among the shortest in the nation. Missouri imposes no mandatory separation period before you file.
The 30-day waiting period begins the day the petition is filed, not the day the other spouse is served. For an uncontested divorce where both spouses agree, 30 days is the practical floor, though court scheduling often pushes the final hearing somewhat later. For contested divorces involving disputes over property, custody, or support, cases typically take several months to a year or more, far exceeding the 30-day minimum. Missouri does not require spouses to live separately for any period before filing, which differs from states that mandate a separation. However, living "separate and apart" for 12 or 24 months becomes relevant only as a statutory ground in contested cases where one spouse denies the marriage is irretrievably broken under Mo. Rev. Stat. § 452.320.
What Are the Grounds for Divorce in Missouri?
Missouri is a no-fault divorce state, requiring only that the marriage be "irretrievably broken" with no reasonable likelihood of reconciliation under Mo. Rev. Stat. § 452.320. Neither spouse must prove wrongdoing. If one spouse denies the marriage is irretrievably broken, the petitioner must prove one of five statutory facts.
When both spouses agree the marriage is irretrievably broken, or one states it and the other does not deny it, the court enters a judgment of dissolution after a hearing. When one spouse contests the breakdown under oath, Mo. Rev. Stat. § 452.320 requires the petitioner to prove one of five facts: (1) the respondent committed adultery making cohabitation intolerable; (2) the respondent behaved so that the petitioner cannot reasonably be expected to live with them; (3) the respondent abandoned the petitioner for at least six continuous months; (4) the parties lived separate and apart by mutual consent for 12 continuous months; or (5) the parties lived separate and apart for at least 24 continuous months. These contested grounds make the separation timeline directly relevant to how a denied divorce proceeds.
How Is Property Divided in a Missouri Divorce?
Missouri divides marital property through equitable distribution, meaning the court splits assets fairly but not necessarily equally, under Mo. Rev. Stat. § 452.330. Missouri is not a community property state. Courts first set aside each spouse's separate property, then divide marital property and debts in proportions the judge considers just.
Under Mo. Rev. Stat. § 452.330, the court presumes all property acquired between the marriage date and the final decree is marital property, regardless of whose name is on the title. Judges weigh factors including each spouse's economic circumstances, contributions to acquiring the property, conduct during the marriage, and the custodial arrangement for any children. Notably, Missouri does not automatically convert separate property to marital property when it is commingled; separate property keeps its nonmarital status unless the owning spouse intended to make it marital. Marital debts are divided under the same equitable framework. Case law makes the division of marital property mandatory, and a dissolution judgment that fails to divide marital property is not a final, appealable judgment.
Can a Pregnant Woman Get Divorced in Missouri?
Under long-standing Missouri practice dating to 1973, a pregnant spouse can file for divorce, but a judge has historically delayed the final decree until after the child's birth so paternity and child support can be determined. In 2026, the Missouri Legislature advanced a bill removing that barrier so pregnancy status will not prevent entry of a dissolution judgment.
Missouri's pregnancy rule has drawn national attention because it could trap a pregnant spouse, including a victim of domestic violence, in a marriage until delivery. As of March 2026, the Missouri Senate unanimously approved legislation clarifying that pregnant women can finalize a divorce, sending the bill to Gov. Mike Kehoe, who had requested its passage during his State of the State address. The reform, sponsored by Reps. Cecelie Williams and Raychel Proudie, adds language stating "pregnancy status shall not prevent the court from entering a judgment of dissolution of marriage or legal separation." The law still requires parties to disclose pregnancy so custody and support can be addressed. Because the legislative status changes rapidly, confirm the current law with a Missouri attorney or the Missouri General Assembly before relying on it.
