Missouri grants divorce on a single no-fault ground: the marriage is irretrievably broken with no reasonable likelihood it can be preserved. One spouse must have lived in Missouri for at least 90 days before filing, and a 30-day cooling-off period applies after the petition is filed. No separation period is required.
Grounds for divorce in Missouri
Missouri allows only one ground for divorce: the marriage is irretrievably broken, meaning there is no reasonable likelihood that it can be preserved. This language comes directly from RSMo 452.305. Missouri is a no-fault-only state, which means neither spouse needs to prove or allege wrongdoing such as adultery, cruelty, or abandonment. Traditional fault-based defenses, like recrimination or condonation, were abolished when Missouri adopted no-fault divorce.
When a petition is filed, the court will make a finding that the marriage is irretrievably broken based on the parties' statements and any supporting facts. If both spouses agree, the process is straightforward. If the respondent denies the breakdown, the court may continue the matter for a further hearing not less than 30 days nor more than 6 months later and may suggest, but not require, counseling (RSMo 452.320). At that hearing, the petitioner can still obtain the divorce by proving one of the statutory facts, such as abandonment or a set period of separation.
Because Missouri has no fault grounds, there is no strategic advantage to alleging misconduct in the divorce petition itself. However, a spouse's economic misconduct, such as dissipating marital assets, can still be considered when the court divides property.
Starting August 28, 2026, RSMo 452.305 also provides that pregnancy status does not prevent the court from entering a judgment of dissolution of marriage or legal separation (HB 1908, signed April 7, 2026). This change ends Missouri's earlier practice of sometimes holding a divorce open until after the child's birth.
Residency requirement
To file for divorce in Missouri, at least one spouse must have been a Missouri resident or stationed there as a member of the armed forces for a minimum of 90 days immediately before the case begins (RSMo 452.305). There is no requirement that the petitioner be the resident; either party satisfies the rule.
Divorce cases in Missouri are heard in the Circuit Court. You file in the circuit court of the county where either you or your spouse currently lives. Missouri has 46 circuit court circuits covering all 114 counties and the City of St. Louis. Each circuit has a family court division (or a judge assigned to family matters) that handles dissolution of marriage cases.
If neither party has yet met the 90-day residency requirement, you must wait until one of you qualifies before filing. Attempting to file before the residency threshold is met gives the court grounds to dismiss the petition.
Waiting period and separation
These two concepts are distinct, and Missouri treats them differently.
The waiting period in Missouri is 30 days. After the petition for dissolution is filed and served, Missouri law requires that at least 30 days elapse before the court may enter a judgment of dissolution (RSMo 452.305). This is a procedural cooling-off period, not a requirement that the spouses live apart.
Missouri has no separation requirement. You do not need to live apart from your spouse for any set period before you are eligible to file. The petition must state the date the parties last cohabited together as spouses, but that date can be recent. There is no minimum gap between the end of cohabitation and the filing date.
In a contested divorce, the overall timeline is driven by factors such as discovery, negotiation, and court scheduling, not by any statutory separation clock. An uncontested divorce can often be finalized shortly after the 30-day waiting period expires if all terms are agreed upon and paperwork is in order.
How property is divided
Missouri is an equitable distribution state, not a community property state. Only nine states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin) use community property, which generally splits marital assets 50/50. Missouri, like most states, divides marital property equitably, meaning fairly given the circumstances, but not necessarily in equal halves.
Under RSMo 452.330, the court divides only marital property, which generally means assets and debts acquired by either spouse during the marriage, regardless of whose name is on the title. Separate property, meaning assets owned before marriage or received as a gift or inheritance during the marriage and kept separate, is typically returned to the spouse who owns it.
The court weighs several factors when deciding what is equitable: the economic circumstances of each spouse, contributions to acquiring the marital property (including homemaking), the value of separate property, the conduct of each party during the marriage (economic misconduct can be considered), and any custodial arrangements for children. The goal is a division that is just under all the facts, which often approximates equal but may depart from it when circumstances justify.
Alimony, custody, and child support
Alimony (called "maintenance" in Missouri), child custody, and child support are all resolved as part of, or alongside, the dissolution proceeding. Maintenance may be awarded if one spouse lacks sufficient property to meet reasonable needs and is unable to support themselves through employment (RSMo 452.335). It can be for a fixed term or, in longer marriages with a significant earning disparity, open-ended.
Child custody in Missouri is decided under a best-interest-of-the-child standard. Missouri courts can award joint legal custody, joint physical custody, or sole custody depending on the circumstances. The custody arrangement then feeds directly into the child support calculation, which follows Missouri's Income Shares model. Estimate your payment with our Missouri child support calculator.

How to file for divorce in Missouri
Filing for divorce in Missouri involves several practical steps.
First, confirm residency. Make sure you or your spouse have lived in Missouri for at least 90 days before you file.
Second, prepare and file the petition. The petitioner files a Petition for Dissolution of Marriage in the Circuit Court of the appropriate county. Missouri's courts provide self-help forms, and many circuits maintain family court facilitators for unrepresented parties. You will pay a filing fee at the time of filing; fees vary by county.
Third, serve the respondent. After filing, you must formally serve your spouse with the petition and summons. Service can be by sheriff, private process server, or acceptance of service if your spouse agrees to waive formal service.
Fourth, exchange financial disclosures. Both parties are required to provide financial information, including income, assets, debts, and expenses. In contested cases, formal discovery (depositions, interrogatories, document requests) may follow.
Fifth, reach a settlement or proceed to trial. Most Missouri divorces are resolved through a negotiated Separation Agreement that addresses property division, maintenance, custody, and support. If the parties cannot agree, the court holds a trial and the judge decides the open issues.
Sixth, receive the decree. Once the 30-day waiting period has passed and all issues are resolved, the court enters a Judgment of Dissolution of Marriage, which is the final order ending the marriage.

Frequently Asked Questions
How long does it take to get a divorce in Missouri?
The minimum is just over 30 days, since a judgment cannot enter until 30 days after filing. Most uncontested divorces take 60 to 90 days from filing to final decree. Contested divorces can take 6 months to over a year, depending on the complexity of issues and court scheduling.
How much does a divorce cost in Missouri?
Filing fees vary by county but typically range from roughly $150 to $250. Attorney fees depend on whether the divorce is contested; an uncontested divorce handled by one attorney for document preparation may cost a few hundred to a few thousand dollars, while a contested case can run significantly higher.
Do I need a reason to divorce in Missouri?
No. Missouri is a no-fault-only state. You simply need to state that the marriage is irretrievably broken with no reasonable likelihood it can be preserved. You do not have to prove adultery, cruelty, or any other fault-based reason.
Is Missouri a community property state?
No. Missouri uses equitable distribution, not community property. Marital property is divided fairly based on the circumstances of the marriage, which often results in a roughly equal split but does not require one.
How long do I have to be separated to get divorced in Missouri?
Missouri has no separation requirement. You can file for divorce without having lived apart from your spouse at all. The only time-based rule is the 30-day waiting period after the petition is filed before a judgment can be entered.
Can I get divorced without my spouse agreeing in Missouri?
Yes. Missouri does not require mutual consent. If your spouse contests the divorce or denies the breakdown, the court may continue the matter for a further hearing not less than 30 days nor more than 6 months later (RSMo 452.320), but the court can ultimately grant the dissolution if you prove one of the statutory facts, such as abandonment or a set period of separation.
Do I have to live in Missouri to file for divorce there?
At least one spouse must have been a Missouri resident or stationed there in the military for 90 days before filing. If only your spouse meets this requirement, you can still be the petitioner as long as one of you qualifies.
