Understanding how to file for divorce in Montana is one of the most important steps in your divorce preparation. This guide covers what Montana law requires, what to expect, and how to prepare — in plain language, not legalese.
Section · 01
Before filing for divorce in Montana, at least one spouse must have lived in the state for the required period (90 days). Military members stationed in Montana may also qualify.
Section · 02
Montana recognizes no-fault divorce grounds, and in many cases fault-based grounds as well. Most divorces proceed on no-fault grounds.
Section · 03
The divorce process begins when one spouse (the petitioner) files a petition for dissolution of marriage with the appropriate court. In Montana, this is filed with the District Court in the county where either spouse lives. The filing fee is approximately $200.
Section · 04
After filing, the petition must be formally served on the other spouse (the respondent). Montana allows service by personal service, service by mail, or constructive service in limited circumstances. The respondent typically has 20 days to respond.
Section · 05
Montana has a 20-day waiting period. Courts may require completion of additional steps such as parenting courses if children are involved.
Section · 06
Once all issues are resolved — either by agreement or court decision — the court enters a final judgment of dissolution. In Montana, this covers property division, equitable distribution of assets, spousal support, child custody, and child support.
What Makes Montana Different
Montana is a pure no-fault state — the only ground is 'irretrievable breakdown.' The state requires a 20-day waiting period from service — one of the shortest in the country.
FAQ
Montana has a 20-day waiting period. Uncontested divorces typically finalize in 2-6 months depending on your court's schedule. Contested cases can take 6-18 months or longer.

You don't need your spouse's consent to get divorced. If your spouse doesn't respond to the petition after being served, the court can grant a default judgment. The process takes longer but the divorce can proceed without cooperation.
Typically: the petition for dissolution, a summons, financial declarations, and if children are involved, a parenting plan. You'll also need 3-5 years of tax returns, pay stubs, bank statements, and property records. DIVORSAY's Evidence Vault helps you organize all of this.
