Missouri Divorce Filing Requirements
Before you can file for divorce in Missouri, you must meet these requirements:
| Residency Requirement | 90 days — at least one spouse must have been a resident of Missouri (or a member of the armed services stationed in Missouri) for 90 days immediately preceding the filing of the petition (RSMo 452.305) |
| Filing Fee | 133 to 225 depending on county; counties with minor children typically charge 75 to 100 more; verify with local circuit clerk |
| No-Fault Grounds | Yes — Missouri allows no-fault divorce using the language “irretrievably broken” (the court must find that there remains no reasonable likelihood that the marriage can be preserved and that the marriage is irretrievably broken, per RSMo 452.320) |
| Waiting Period | 30 days — a minimum of 30 days must elapse after the filing of the petition before the court may enter a judgment of dissolution (RSMo 452.305) |
| Separation Requirement | NONE for uncontested (both parties agree marriage is irretrievably broken). If one party denies the marriage is irretrievably broken, the petitioner may need to prove 12 months of separation by mutual consent or 24 months of separation without mutual consent as one of the alternative statutory grounds under RSMo 452.320 |
| Property Division | Equitable distribution |
| Uncontested Available | YES |
| Online Filing | YES — Missouri courts allow electronic filing of circuit court documents through their e-filing system; however, availability and procedures vary by county, and some counties may still require in-person filing for dissolution cases |
Residency: At least one spouse must have been a resident of Missouri for 90 days — at least one spouse must have been a resident of Missouri (or a member of the armed services stationed in Missouri) for 90 days immediately preceding the filing of the petition (RSMo 452.305) before filing. You file in the county where either spouse resides.
Missouri Fault-Based Divorce Grounds
In addition to no-fault divorce, Missouri allows divorce on these fault-based grounds:
- Missouri is technically a no-fault state (there is no separate fault-based filing)
- but if one party denies under oath that the marriage is irretrievably broken
- the petitioner must prove at least one of these statutory factors under RSMo 452.320: (a) adultery and the petitioner finds it intolerable to live with the respondent; (b) the respondent behaved in such a way that the petitioner cannot reasonably be expected to live with them (cruel treatment/intolerable behavior); (c) abandonment for a continuous period of at least 6 months; (d) the parties lived separate and apart by mutual consent for 12 continuous months; (e) the parties lived separate and apart for 24 continuous months
Filing on fault grounds may affect property division, alimony, or custody decisions in some Missouri courts. However, most divorces in Missouri proceed on no-fault grounds because they are simpler and faster.
Step-by-Step Missouri Divorce Process
- Meet residency requirements: Confirm you or your spouse has lived in Missouri for the required period.
- Prepare your petition: Complete the Petition for Dissolution of Marriage (or equivalent Missouri form). Include grounds, requests for property division, custody, and support.
- File with the court: Submit your petition to the circuit/family court in the appropriate county. Pay the filing fee (approximately 133 to 225 depending on county; counties with minor children typically charge 75 to 100 more; verify with local circuit clerk).
- Serve your spouse: Your spouse must be formally served with divorce papers via sheriff, process server, or certified mail (rules vary by Missouri county).
- Response period: Your spouse has a set number of days (typically 20-30) to file a response.
- Negotiation/discovery: Spouses exchange financial information and negotiate terms on property, custody, and support.
- Waiting period: 30 days — a minimum of 30 days must elapse after the filing of the petition before the court may enter a judgment of dissolution (RSMo 452.305) must pass before the divorce can be finalized.
- Final hearing/decree: The judge reviews and approves the settlement agreement or makes rulings on contested issues. The divorce decree is entered.
Parenting class: Missouri requires divorcing parents with minor children to complete a court-approved parenting education class. These classes cover the impact of divorce on children and co-parenting strategies.
Missouri Property Division
Missouri follows equitable distribution for dividing marital property. This does not necessarily mean 50/50 — the court divides assets fairly based on factors including the length of the marriage, each spouse’s income and earning potential, contributions to marital property, and the needs of each party.
Under RSMo 452.330, the court sets apart each spouse’s nonmarital (separate) property and divides marital property and marital debts in proportions the court deems just after considering all relevant factors including: (1) the economic circumstances of each spouse at the time the division becomes effective, including desirability of awarding the family home to the custodial parent; (2) the contribution of each spouse to the acquisition of marital property, including contribution as homemaker; (3) the value of nonmarital property set apart to each spouse; (4) the conduct of the parties during the marriage, including economic misconduct. Division does not need to be equal, only just. The judgment on property division is final and not subject to modification.
Key assets to consider: Real estate, retirement accounts (401k, pensions, IRAs), business interests, vehicles, investment accounts, debts, and personal property. Some assets may require professional appraisal or a Qualified Domestic Relations Order (QDRO) for retirement account division.

How Long Does Divorce Take in Missouri?
Uncontested divorce: 30 to 90 days from filing — the legal minimum is 30 days, but most uncontested cases finalize in approximately 60 to 90 days due to court scheduling and document review
Contested divorce: 6 to 12 months on average; complex cases involving custody disputes or significant assets may exceed 12 months; courts generally aim to resolve within 12 months
These timelines are approximate. Court backlogs, complexity of issues, and whether children are involved can significantly affect the actual duration.
Uncontested Divorce in Missouri
An uncontested divorce in Missouri is available when both spouses agree on all major issues: property division, child custody, child support, and alimony. Both spouses must agree that the marriage is irretrievably broken and agree on all terms including property division, debt allocation, child custody, child support, and spousal maintenance. Both must sign the petition or one files and the other does not deny the marriage is irretrievably broken under oath. Standard court forms from the Missouri Supreme Court must be used by self-represented parties. Forms include Petition for Dissolution, Income and Expense Statement, Statement of Property and Debt, Filing Information Sheet, Certificate of Dissolution, proposed Judgment, and a Parenting Plan if minor children are involved.
Benefits of uncontested divorce include lower attorney fees, faster resolution, less emotional stress, and greater privacy since contested hearings are public.
Missouri Divorce Costs
Divorce costs in Missouri vary widely based on complexity:
| Type | Estimated Cost Range |
|---|---|
| Filing Fee | 133 to 225 depending on county; counties with minor children typically charge 75 to 100 more; verify with local circuit clerk |
| Uncontested (no attorney) | $300 – $1,500 |
| Uncontested (with attorney) | $1,500 – $5,000 |
| Contested (with attorney) | $5,000 – $30,000+ |
| Mediation | $2,000 – $8,000 |
Fee waivers may be available for low-income filers. Contact the court clerk in your county for fee waiver applications.
Additional Missouri rules: (1) Missouri calls divorce “dissolution of marriage” — the term “divorce” is not used in the statutes. (2) A 2026 bill (HB 1908, truly agreed and finally passed) amended RSMo 452.305 and 452.310, including a provision that pregnancy status shall not prevent the court from entering a judgment of dissolution. (3) The court’s property division judgment is final and cannot be modified post-decree (RSMo 452.330). (4) If one party denies the marriage is irretrievably broken, the court may continue the matter for 30 to 180 days and may suggest counseling. (5) Social Security numbers have updated disclosure rules in filings per recent legislative changes.
