Montana Divorce Filing Fees and Court Costs in 2026
The standard filing fee for a divorce in Montana is $200, established under Mont. Code Ann. § 25-1-201, making it one of the lower filing fees in the western United States. Some counties assess an additional judgment fee of approximately $50, bringing the total to $250 in those jurisdictions. Filing fee waivers are available for filers who cannot afford the cost by submitting an Affidavit of Inability to Pay Filing Fee. As of March 2026, verify current fees with your local district court clerk.
Beyond the base filing fee, additional costs depend on the complexity of the case. Service of process typically costs $30 to $75 if a sheriff or private process server delivers papers to the other spouse. A joint petition eliminates service costs entirely because both spouses sign and file together. Certified copies of the final decree cost approximately $2 to $5 per page. For a fully uncontested cheap divorce in Montana where both spouses agree on everything, total out-of-pocket costs can remain between $200 and $350.
Attorney fees in Montana range from $150 to $350 per hour, with contested divorces averaging $5,000 to $15,000 or more depending on disputes over property, maintenance, or parenting plans. An uncontested divorce handled by an attorney typically costs $1,500 to $3,500 for flat-fee representation. Online divorce document preparation services charge $150 to $500 to complete the paperwork for you, though these services cannot provide legal advice.
| Cost Category | Low Estimate | High Estimate |
|---|---|---|
| Filing Fee | $200 | $250 |
| Service of Process | $0 (joint petition) | $75 |
| Certified Copies | $5 | $20 |
| DIY Total | $200 | $350 |

Residency Requirements for Filing in Montana
Montana requires at least 90 days of continuous domicile in the state immediately before filing for divorce, as established by Mont. Code Ann. § 40-4-104. This 90-day residency requirement is among the shortest in the United States, where many states require 6 months or even 1 year of residency. Military personnel stationed in Montana also satisfy the domicile requirement under the same statute.
Domicile means more than physical presence; the filing spouse must intend Montana to be their permanent home. Maintaining a Montana driver's license, voter registration, and mailing address supports establishing domicile. If children are involved, Montana must have been the child's home state for at least 6 consecutive months to establish custody jurisdiction under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA). The 90-day domicile requirement applies to at least one spouse, not both.
Grounds for Divorce in Montana
Montana is an exclusively no-fault divorce state, and the sole ground for dissolution of marriage is irretrievable breakdown, as defined in Mont. Code Ann. § 40-4-104. Montana law does not recognize fault-based grounds such as adultery, abandonment, or cruelty. This no-fault approach simplifies the filing process and reduces litigation costs, making an affordable divorce in Montana more attainable for most couples.
To establish irretrievable breakdown, the filing spouse must demonstrate one of two conditions under the statute. The first option is proving that the spouses have lived separate and apart for more than 180 continuous days immediately before filing. The second option is showing that serious marital discord exists which adversely affects the attitude of one or both parties toward the marriage, with no reasonable prospect of reconciliation. If both spouses agree the marriage is irretrievably broken, the court accepts the finding and moves forward. If one spouse denies the breakdown, the court may order a continuance of 30 to 60 days and may recommend counseling under Mont. Code Ann. § 40-4-107.
How to File for an Uncontested Divorce in Montana
An uncontested divorce in Montana can be finalized in as few as 21 days after filing, with most cases completing within 30 to 90 days. Under Mont. Code Ann. § 40-4-105(3), the court may not enter a final decree until at least 21 days have passed from the date of service or joint petition filing. This mandatory waiting period cannot be waived by the court under any circumstances.

- Download the free dissolution forms from the Montana Courts Self-Help Center at courts.mt.gov/forms/end_marriage. Choose the packet for dissolution with children or without children as appropriate.

- Prepare a written marital settlement agreement addressing property division, debt allocation, and maintenance (if applicable).
- Complete the Declarations of Disclosure of Income and Expenses for both spouses.

- Complete the Vital Statistics form required by the state.
- File all documents with the district court clerk in the county where either spouse resides and pay the $200 filing fee.

Property Division in Montana Divorce
Montana follows equitable distribution for dividing marital property, meaning the court divides assets fairly but not necessarily equally. Under Mont. Code Ann. § 40-4-202, the court must equitably apportion all property and assets belonging to either or both spouses, regardless of when or how the property was acquired and regardless of whose name appears on the title. Montana does not distinguish between marital and separate property the way many other equitable distribution states do.
The court considers multiple factors when dividing property: the duration of the marriage, the age and health of each spouse, each spouse's occupation and income, vocational skills and employability, the needs of each party, child custody arrangements, future economic opportunities, and the terms of any prenuptial agreement. Marital misconduct is explicitly prohibited from consideration in property division under Mont. Code Ann. § 40-4-202. For couples pursuing a low cost divorce in Montana, reaching a property agreement outside of court eliminates the expense and unpredictability of judicial division.
Maintenance (Alimony) in Montana
Montana courts may award maintenance (the state's term for alimony) when a spouse lacks sufficient property to meet reasonable needs and is unable to become self-supporting through appropriate employment. Under Mont. Code Ann. § 40-4-203, both conditions must be met before the court will consider a maintenance award. A spouse who is the custodian of a child whose condition makes outside employment inappropriate also qualifies for maintenance.
Montana does not use a fixed formula to calculate maintenance amounts or duration. Judges exercise broad discretion based on several factors: the financial resources of the requesting spouse, the time needed to acquire education or job training, the standard of living established during the marriage, the length of the marriage, the age and health of the requesting spouse, and the paying spouse's ability to meet their own needs while making maintenance payments. Marital misconduct cannot be considered in maintenance decisions. The court may award temporary maintenance during the divorce proceedings under Mont. Code Ann. § 40-4-121, short-term maintenance for a defined period, or permanent maintenance in long-term marriages where the receiving spouse cannot become self-supporting.
Child Custody and Support in Montana
Montana uses the term "parenting plan" rather than traditional custody and visitation language, and all custody decisions follow the best interest of the child standard under Mont. Code Ann. § 40-4-212. Montana law establishes a presumption that frequent and continuing contact with both parents is in the child's best interest. The court evaluates 10 statutory factors including each parent's wishes, the child's wishes, relationships with family members, adjustment to home and school, mental and physical health of all parties, and any history of physical abuse or chemical dependency.
Child support in Montana follows the income shares model, where both parents' incomes are used to calculate support obligations under Mont. Code Ann. § 40-4-204 and the administrative rules at Mont. Admin. R. 37.62.105 through 37.62.148. Support is calculated on an annual basis and paid in equal monthly installments. Full-time employment is presumed at 40 hours per week. The guidelines create a rebuttable presumption of adequacy, meaning deviation from the calculated amount requires clear and convincing evidence that strict application would be unjust. Parents can use the child support worksheets available at the Montana DPHHS Child Support Services Division website to estimate their obligations.
Free and Low-Cost Divorce Resources in Montana
Montana provides several free resources that make an affordable divorce accessible to residents at every income level. The Montana Legal Services Association (MLSA) offers free legal assistance to low and moderate-income residents through offices in Billings, Helena, and Missoula. The MLSA HelpLine at 1-800-666-6899 operates Tuesday through Thursday from 9 AM to 1 PM and provides legal consultations, referrals, and in some cases full representation at no cost.
The Montana LawHelp website at montanalawhelp.org provides a comprehensive DIY divorce guide titled "The Ultimate DIY Guide to Divorce and Custody in Montana," which walks self-represented filers through every step of the process. The site also offers a free automated form generator that creates customized dissolution petitions based on the filer's answers to guided questions. The Montana Courts Self-Help Center at courts.mt.gov/selfhelp provides free downloadable forms, instructions, and procedural guides.
For a budget divorce in Montana, the most cost-effective approach combines free court forms with the MLSA's legal guidance. Couples who agree on all terms can complete their entire divorce for just the $200 filing fee. Fee waivers reduce even that cost to $0 for those who qualify based on income. Montana's 2025 legislative expansion of simplified dissolution (SB 372) to include couples with children and agreed-upon parenting plans further reduces the barriers to an inexpensive, streamlined process.
Mediation as a Cost-Saving Alternative
Montana law authorizes family law mediation under Mont. Code Ann. § 40-4-301 through § 40-4-307, and mediation is not mandatory for initial divorce proceedings. Either party may request the court to order mediation, and courts frequently encourage it as a means to resolve disputes without the expense of litigation. Private mediators in Montana typically charge $100 to $300 per hour, with most uncontested mediations completing in 2 to 4 sessions for a total cost of $500 to $2,000 split between both spouses.
Montana law provides an important protection for domestic violence survivors: the court may not authorize mediation if there is reason to suspect physical, sexual, or emotional abuse by one party against the other or against a child, unless both parties provide written informed consent under Mont. Code Ann. § 40-4-301. If mediation proceeds in such cases, it must be conducted by a mediator specifically trained in domestic violence dynamics. For parenting plan amendments after the divorce is finalized, mediation is required before filing a motion to modify under Mont. Code Ann. § 40-4-219, subject to the same domestic violence exception.
Simplified Dissolution in Montana
Montana offers a simplified (summary) dissolution process that provides the fastest and cheapest path to divorce. The 2025 legislative session expanded eligibility through SB 372 to include couples with children who have an agreed-upon parenting plan. Previously, simplified dissolution was limited to couples without minor children. Both spouses must agree that the marriage is irretrievably broken and meet the 90-day residency requirement under Mont. Code Ann. § 40-4-104.
The simplified process eliminates many of the procedural steps required in a standard dissolution, including formal discovery and potentially a court hearing. Both spouses file a joint petition, submit their settlement agreement, and the court can enter a decree after the 21-day waiting period without requiring either party to appear before the judge. For couples seeking a cheap divorce in Montana, simplified dissolution offers the most direct route, with total costs as low as $200 when using the free court forms.
