Filing for divorce in Missouri requires meeting a 90-day residency requirement, paying filing fees ranging from $130 to $300 depending on your county, and waiting a mandatory 30-day cooling-off period before your divorce can be finalized. Under RSMo § 452.305, Missouri courts will grant a dissolution of marriage when the court finds the marriage is irretrievably broken and statutory requirements are satisfied. This guide covers every step of how to file for divorce in Missouri, from preparing your petition to obtaining your final judgment.
| Key Fact | Missouri Requirement |
|---|---|
| Filing Fee | $130–$300 (varies by county) |
| Waiting Period | 30 days minimum |
| Residency Requirement | 90 days for at least one spouse |
| Grounds for Divorce | No-fault (irretrievably broken) |
| Property Division | Equitable distribution |
| Custody Presumption | Equal or approximately equal parenting time |
Missouri Residency Requirements for Divorce
At least one spouse must have been a Missouri resident for 90 consecutive days immediately before filing the divorce petition. Under RSMo § 452.305(1), this 90-day residency requirement is a jurisdictional prerequisite, meaning the court cannot legally grant your divorce if the requirement is not satisfied. Military personnel stationed in Missouri for 90 days also meet this requirement. Missouri does not impose a county residency requirement, so you may file in the county where either spouse resides.
The residency requirement ensures Missouri courts have proper jurisdiction over your dissolution case. If you recently moved to Missouri, you must wait until you have lived in the state for 90 days before filing your Petition for Dissolution of Marriage. Courts verify residency through driver's licenses, utility bills, lease agreements, or sworn statements in the petition.
Missouri Divorce Filing Fees by County
Missouri divorce filing fees range from $130 to $300 depending on which county circuit court handles your case. Filing fees as of March 2026 vary significantly across Missouri's 114 counties and the City of St. Louis. You should verify current fees with your local circuit court clerk before filing, as fees change periodically.
| County | Filing Fee |
|---|---|
| Jackson County | $177.50 |
| Cass County | $163.50 |
| Morgan County | $132.50 |
| Jasper County | $127.50 |
| Lawrence County | $127.50 |
Missouri courts offer fee waivers for low-income filers who cannot afford filing costs. To request a fee waiver, complete Form CC 375 (Application to Proceed Without Payment) and submit proof of income. Courts typically grant waivers when household income falls below 125% of the federal poverty line. Additional costs include certified copies of the decree ($5–$15 each), sheriff service fees ($25–$50), and private process server fees ($40–$100).
The 30-Day Waiting Period in Missouri
Missouri imposes a mandatory 30-day waiting period between filing the divorce petition and the earliest date the court may grant a final judgment. Under RSMo § 452.305, the court cannot enter a judgment of dissolution until thirty days have elapsed since the filing of the petition. This waiting period cannot be waived, even if both spouses agree to all terms of their divorce.
The 30-day cooling-off period serves two purposes under Missouri law. First, it provides couples an opportunity for reflection and potential reconciliation. Second, it ensures adequate time for proper service of process and the respondent's opportunity to file a response. In practice, uncontested divorces typically take 30 to 90 days to finalize, while contested divorces involving custody disputes, complex property, or trial may take 6 to 24 months.
Grounds for Divorce in Missouri
Missouri is a no-fault divorce state where the primary ground for dissolution is that the marriage is irretrievably broken. Under RSMo § 452.320, if both spouses state under oath that the marriage is irretrievably broken, the court will make its finding and enter an order accordingly. Neither spouse needs to prove wrongdoing by the other to obtain a divorce in Missouri.
When one spouse denies the marriage is irretrievably broken, Missouri law provides alternative grounds under RSMo § 452.320(2). The petitioning spouse must prove one of five statutory grounds:
- Adultery that makes living together intolerable
- Behavior making it unreasonable to expect continued cohabitation
- Abandonment for at least six continuous months
- Separation by mutual consent for 12 continuous months
- Separation without consent for 24 continuous months
The court may also continue the matter for 30 to 180 days and suggest counseling, though no Missouri court can require counseling as a condition for granting a divorce.
Step-by-Step Process to File for Divorce in Missouri
Filing for divorce in Missouri involves preparing and filing official court forms, serving your spouse, and either negotiating a settlement or proceeding to trial. The process begins when you file a Petition for Dissolution of Marriage (Form CAFC001) with your county circuit court.
Step 1: Gather Required Documents
Before you file for divorce in Missouri, collect essential documents including marriage certificates, financial records, property deeds, vehicle titles, tax returns for the past three years, bank statements, retirement account statements, and documentation of debts. If children are involved, gather birth certificates, school records, and medical information.
Step 2: Complete the Petition for Dissolution of Marriage
Download the official Petition for Dissolution of Marriage (Form CAFC001) from the Missouri Courts website at courts.mo.gov. Complete the form with information about your marriage, grounds for divorce, and requests for property division, custody, and support. The petition must be verified under oath before a notary public.
Step 3: Prepare Additional Required Forms
Missouri requires several additional forms alongside the petition:
- Income and Expense Statement (Form CAFC300)
- Statement of Property and Debt (Form CAFC310)
- Filing Information Sheet (Form CAFC370)
- Parenting Plan (Form CAFC402) if children are involved
- Certificate of Dissolution (Form CAFC100)
- Proposed Judgment of Dissolution of Marriage
Step 4: File Your Petition with the Circuit Court
File your completed petition and supporting documents with the circuit court clerk in the county where you or your spouse resides. Pay the filing fee (typically $130–$300) or submit a fee waiver application. The clerk will assign a case number and return file-stamped copies of your documents.
Step 5: Serve Your Spouse
After filing, you must formally serve your spouse with copies of all filed documents. Missouri allows service by sheriff ($25–$50), private process server ($40–$100), or certified mail with return receipt requested. Your spouse has 30 days from service to file a response. If your spouse waives service in writing, formal service is not required.
Step 6: Negotiate Settlement or Proceed to Trial
If both spouses agree on all issues, you can file a settlement agreement and request an uncontested divorce hearing. If disputes remain, the case becomes contested and may require discovery, mediation, and ultimately trial. Missouri courts encourage settlement through mediation, which typically costs $200–$400 per hour.
Missouri Property Division Laws
Missouri divides marital property using equitable distribution principles rather than a strict 50/50 split. Under RSMo § 452.330, courts set apart each spouse's nonmarital property and divide marital property and debts in proportions the court deems just after considering all relevant factors. The court's property division order is final and not subject to modification.
Marital property includes all property acquired by either spouse during the marriage, regardless of whose name appears on the title. Nonmarital property includes property acquired before marriage, property acquired by gift or inheritance, and property excluded by valid written agreement. Missouri follows the source of funds rule, meaning separate property used to acquire marital property retains its nonmarital character unless the owner specifically intended to convert it.
| Property Type | Treatment in Divorce |
|---|---|
| Marital home | Subject to equitable division |
| Retirement accounts | Divided via QDRO |
| Business interests | Valued and divided equitably |
| Inheritances | Generally nonmarital property |
| Gifts between spouses | Generally marital property |
| Premarital assets | Nonmarital if not commingled |
Missouri courts consider these factors when dividing property: economic circumstances of each spouse, contributions to marital property acquisition (including homemaker contributions), value of nonmarital property, conduct during the marriage, and custodial arrangements for minor children.
Child Custody in Missouri Divorces
Missouri courts determine child custody based on the best interests of the child with a rebuttable presumption favoring equal or approximately equal parenting time. Under RSMo § 452.375, this presumption took effect following 2023 legislative changes and can only be overcome by a preponderance of evidence showing unequal time serves the child's best interests.
Missouri law requires divorcing parents to submit a parenting plan to the court under RSMo § 452.310(8). The parenting plan must address physical and legal custody arrangements, holiday and vacation schedules, decision-making authority, and procedures for resolving future disputes.
Courts consider these factors when determining custody arrangements:
- Each parent's wishes regarding custody
- The child's need for frequent contact with both parents
- The child's relationship with parents, siblings, and significant others
- Which parent is more likely to allow meaningful contact with the other parent
- The child's adjustment to home, school, and community
- The mental and physical health of all parties
- Any history of domestic violence or abuse
- Either parent's intention to relocate
Joint legal custody means parents share decision-making authority for education, healthcare, and welfare. Joint physical custody means each parent has significant periods of time with the child, though not necessarily equal time.
Child Support Calculations in Missouri
Missouri calculates child support using the Income Shares model through Form 14, the official calculation worksheet required by RSMo § 452.340 and Supreme Court Rule 88.01. A new Form 14 became effective January 1, 2026, updating schedule amounts and calculations. The Form 14 amount creates a rebuttable presumption of the correct support amount.
The child support calculation begins with each parent's monthly gross income from all sources. The form applies deductions for taxes, other children's support, and allowable expenses. Combined adjusted incomes determine the basic support obligation from a schedule, with each parent's share proportional to their income percentage. The support schedule provides amounts up to a combined monthly gross income of $30,000.
Parents may request deviations from Form 14 guidelines under RSMo § 452.340(9) for extraordinary medical needs, educational expenses, the child's resources, each parent's financial resources, or shared custody arrangements. Courts must provide written findings explaining any deviation.
Missouri may extend child support for college-aged children under RSMo § 452.340.5 if the child enrolls in at least 12 credit hours per semester (or 9 hours if working 15+ hours weekly). Courts may modify child support when a continuing and substantial change in circumstances occurs—typically a 20% or greater change in the calculated amount.
Spousal Maintenance (Alimony) in Missouri
Missouri courts may order spousal maintenance under RSMo § 452.335 when a spouse lacks sufficient property to meet reasonable needs and cannot support themselves through employment. Unlike some states, Missouri has no statutory formula, duration limits, or percentage guidelines for maintenance awards. Courts have wide discretion in determining both amount and duration.
To qualify for maintenance, a spouse must demonstrate they lack sufficient property (including their share of marital property) to provide for reasonable needs, and they cannot support themselves through appropriate employment or have custodial responsibilities preventing employment outside the home.
Courts consider these factors when awarding maintenance:
- Financial resources of both spouses
- Time needed for education or training to find appropriate employment
- Comparative earning capacities
- Standard of living established during marriage
- Obligations and assets of each spouse
- Duration of the marriage
- Age and physical/emotional condition of both spouses
- Ability of the paying spouse to meet their own needs while paying
- Conduct of parties during the marriage
Maintenance terminates automatically upon the death of either spouse or remarriage of the receiving spouse. Modifications require proof of a substantial and continuing change in circumstances that occurred before the maintenance term was set to expire.
2026 Missouri Divorce Law Update: HB 1908
Missouri passed House Bill 1908 in March 2026, clarifying that pregnant women can finalize their divorces during pregnancy. The bill passed the House 147-0 and the Senate 29-0, and takes effect August 28, 2026. Previously, some Missouri judges denied divorce petitions when a wife was pregnant, forcing domestic violence survivors and others to remain legally married until after giving birth.
This legislation addresses a decades-old judicial practice that trapped pregnant women in marriages—including abusive ones. The bill was sponsored by Representative Cecelie Williams (R-Dittmer), a domestic violence survivor who shared her personal story during legislative debate. Missouri becomes the first state to explicitly address this issue through legislation.
Filing for Divorce Online in Missouri
Missouri provides official dissolution of marriage forms online through the Missouri Courts website at courts.mo.gov. These forms are designed for uncontested divorces where both spouses agree on all terms. You must use Adobe Acrobat Reader DC to complete forms online, or print blank forms and complete them by hand.
While Missouri allows you to file for divorce papers online through the court system, you cannot complete the entire divorce process online. You must still file documents with the circuit court clerk (in person, by mail, or through e-filing where available), properly serve your spouse, and attend any required court hearings. The "Find a Court" feature on courts.mo.gov helps locate your local circuit court's filing information and fee schedules.

Since 2023, Missouri law creates a rebuttable presumption that equal or approximately equal parenting time is in the child's best interests under RSMo § 452.375.
