Divorce in Missouri: Laws, Process, and What You Need to Know (2026)

Introduction

Missouri is a strictly no-fault state where the only ground is that the marriage is irretrievably broken. The state's approach to property division is notable because Missouri courts can only divide marital property, leaving separate property untouched.

Missouri is an equitable distribution state for property division purposes. For an overview of how this system works, see our guide to property division. Understanding how Missouri handles divorce can help you prepare for what lies ahead and make informed decisions about your future.

Residency Requirements

To file for divorce in Missouri, you must meet the state's residency requirements: 90 days residency. This means at least one spouse must have lived in Missouri for the required period before the court will accept a divorce filing. You will typically file in the county where either spouse resides.

Grounds for Divorce

Missouri is a strictly no-fault divorce state. The court must find that the marriage is irretrievably broken with no reasonable likelihood of preservation. You do not need to prove wrongdoing by either spouse to obtain a divorce.

Property Division

Missouri follows the equitable distribution approach to dividing property in a divorce. Under this system, the court divides marital property fairly, though not necessarily equally. The judge considers factors like each spouse's economic circumstances, contributions to the marriage (including homemaking), the duration of the marriage, and any dissipation of assets.

Property that either spouse owned before the marriage, as well as gifts and inheritances received individually, is generally considered separate property and is not subject to division. However, if separate property has been commingled with marital assets, it may lose its separate character.

Alimony and Spousal Support

The court considers several factors when determining alimony in Missouri:

• Financial resources
• Time to acquire education/training
• Earning capacity
• Standard of living
• Obligations and assets
• Length of marriage
• Age and health
• Conduct during marriage

In Missouri, alimony is referred to as "maintenance." Courts look at whether the requesting spouse lacks sufficient property and is unable to be self-sufficient through employment.

For a comprehensive overview of alimony types and negotiation strategies, see our alimony and spousal support guide. The duration and amount of alimony depend heavily on the length of the marriage and the financial circumstances of both parties. Short-term marriages are less likely to result in long-term alimony awards.

Child Support

Missouri uses the Income Shares model for calculating child support, with guidelines based on combined adjusted gross income of both parents.

See our child support guide for a detailed explanation of calculation models and modification rules. Either parent can request a modification of child support if there is a substantial change in circumstances, such as a significant change in income, job loss, or a change in the child's needs.

Child Custody

Missouri courts determine custody based on the best interests of the child standard. The court evaluates a range of factors including each parent's relationship with the child, the child's adjustment to home and community, the mental and physical health of all parties, and the willingness of each parent to foster a relationship between the child and the other parent.

Most states, including Missouri, recognize both legal custody (decision-making authority regarding education, healthcare, and welfare) and physical custody (where the child lives). Both types can be awarded jointly or solely to one parent.

Mediation

Mediation is not required in Missouri, though it is often encouraged.

Filing Fees and Costs

Filing fees for divorce in Missouri typically range from $100-$200, though exact amounts vary by county. Additional costs may include:

• Attorney fees (if you hire a lawyer)
• Mediation or alternative dispute resolution fees
• Process server or publication fees
• Costs for financial experts or appraisers (in complex asset cases)
• Court-mandated parenting class fees (if children are involved)

Uncontested divorces are generally significantly less expensive than contested cases.

Key Considerations

• Waiting period: 30 days after filing

If you and your spouse can agree on the major issues, including property division, support, and custody, an uncontested divorce will save you significant time and money. Even in contested cases, exploring mediation or collaborative divorce may lead to a better outcome than a courtroom battle.

Frequently Asked Questions About Missouri Divorce

Is Missouri a community property state?

No, Missouri is not a community property state. Missouri uses equitable distribution to divide marital property. The court divides assets and debts in a manner that is fair and just, but not necessarily equal. Importantly, Missouri courts can only divide marital property, leaving each spouse's separate property completely untouched, which provides strong protection for pre-marital assets and inheritances.

How is property divided in a Missouri divorce?

Missouri courts divide marital property through equitable distribution. The court considers factors including each spouse's economic circumstances, contributions to the acquisition of marital property, the value of non-marital property, each spouse's conduct during the marriage, custodial arrangements, and the desirability of awarding the family home to the custodial parent. A key distinction in Missouri is that the court can only divide marital property and cannot touch separate property.

How long does a divorce take in Missouri?

Missouri has a 30-day mandatory waiting period after filing before a divorce can be finalized. An uncontested divorce where both parties agree on all terms can be completed in approximately one to two months. Contested divorces typically take four months to over a year, depending on the complexity of property division, custody disputes, and other contested issues.

Can I get alimony in Missouri?

Yes, Missouri courts can award maintenance (the Missouri term for alimony) when a spouse lacks sufficient property to meet their reasonable needs and is unable to support themselves through appropriate employment. The court considers factors including financial resources, the time needed for education or training, earning capacity, the standard of living during the marriage, obligations and assets, the length of the marriage, age and health, and the conduct of the parties during the marriage.

What are the grounds for divorce in Missouri?

Missouri is a strictly no-fault divorce state. The only ground for divorce is that the marriage is irretrievably broken with no reasonable likelihood of preservation. You do not need to prove wrongdoing by either spouse. Either spouse can file by asserting that the marriage is irretrievably broken, and the court will grant the divorce if it determines reconciliation is not possible.

What are the residency requirements for divorce in Missouri?

At least one spouse must have been a resident of Missouri for at least 90 days before filing for divorce. The petition is filed in the circuit court of the county where either spouse resides. There is no requirement that both spouses live in Missouri, and the 90-day requirement is one of the shorter residency periods among U.S. states.

How much does a divorce cost in Missouri?

Filing fees for a Missouri divorce typically range from $100 to $200, depending on the county, making Missouri one of the more affordable states for filing. An uncontested divorce without attorneys can cost under $500. Contested divorces with attorney representation generally cost $5,000 to $15,000 or more per spouse. The relatively short 30-day waiting period and no-fault system can help keep costs lower than in states with longer timelines.

Can separate property be divided in a Missouri divorce?

No, Missouri has a strong distinction between marital and separate property. The court can only divide marital property -- assets and debts acquired during the marriage. Separate property, which includes assets owned before the marriage, gifts received individually, inheritances, and property excluded by a valid prenuptial agreement, remains entirely with the original owner. However, if separate property has been commingled with marital property (such as depositing an inheritance into a joint account), it may lose its separate character and become subject to division.
