Grounds for Divorce in Missouri
The marriage is irretrievably broken and there is no reasonable likelihood that the marriage can be preserved.
No-Fault Grounds
- Irretrievably Broken — The court finds there is no reasonable likelihood that the marriage can be preserved and the marriage is therefore irretrievably broken (RSMo § 452.305, § 452.320).
- Separation by Mutual Consent (12 months) — The parties have lived separate and apart by mutual consent for a continuous period of 12 months immediately preceding the filing of the petition (RSMo § 452.320(2)(d)).
- Separation (24 months) — The parties have lived separate and apart for a continuous period of at least 24 months preceding the filing of the petition (RSMo § 452.320(2)(e)).
Fault-Based Grounds
- Adultery — The respondent committed adultery and the petitioner finds it intolerable to live with the respondent (RSMo § 452.320(2)(a)).
- Intolerable Behavior — The respondent has behaved in such a way that the petitioner cannot reasonably be expected to live with the respondent (RSMo § 452.320(2)(b)).
- Abandonment — The respondent has abandoned the petitioner for a continuous period of at least six months preceding the presentation of the petition (RSMo § 452.320(2)(c)).

How to File for Divorce in Missouri
Meet Residency Requirements
You must have lived in Missouri for at least 3 months before filing. One party must be a resident of Missouri or stationed in Missouri as part of the military for at least 90 days before filing (RSMo § 452.305). The petition must be filed in the county where either the petitioner or respondent resides. At least 30 days must pass after filing before the court can enter a judgment of dissolution.
Complete Your Forms
Missouri requires 6 mandatory forms to initiate a divorce. See the full forms list.
File with the Court
File your petition and pay the $163 filing fee. E-filing is available in some counties.
Serve Your Spouse
Accepted service methods: sheriff, personal, certified mail, publication, waiver of service. Service of process in Missouri dissolution cases is governed by Missouri Supreme Court Rule 54 and RSMo § 506.150-506.160. Sheriff service is the default method. Certified mail requires an affidavit showing personal service is impractical. Publication is a last resort requiring court approval.
Wait for Response & Finalize
Your spouse has 30 days to respond. After the 30-day waiting period, the court can issue your final decree.
Special Rules in Missouri
Mandatory Parenting Education
Missouri law (RSMo § 452.600, § 452.605) requires both parents to complete a court-approved parent education program when minor children are involved in a dissolution or custody modification. Programs include Focus on Kids (MU Extension) and FOCIS (Focus on Children in Separation). Cost is approximately $40-$75 per parent.
Pregnancy Restriction Removed (2025)
As of 2025, Missouri law was reformed to allow pregnant women to finalize divorce proceedings before childbirth, reversing the historical precedent that suspended proceedings pending delivery and paternity determination.
Guardian ad Litem
In contested custody cases, the court may appoint a Guardian ad Litem (GAL) to represent the best interests of the children. The cost of the GAL is typically shared between the parties.
Cooperative Divorce Option
Missouri courts encourage cooperative approaches. Many circuits offer mediation programs and some counties allow uncontested divorces to proceed without a hearing if the judge reviews and approves the settlement agreement and documents.
Mandatory Requirements
Parenting Course Required
Both parents must complete a court-approved parent education program when minor children are involved (RSMo § 452.600, § 452.605). Programs include Focus on Kids (MU Extension), FOCIS (Jackson County), and C.O.P.E. (Clay County). Must be completed before final judgment. Cost is approximately $40-$75 per parent.
