How Much Does Divorce Cost in Montana?
Montana's statewide District Court fee schedule lists $200 to file a Petition for Dissolution of Marriage, including summary and joint dissolution proceedings.
That fee is usually a small part of the final expense once professional assistance is involved. A home, ranch or agricultural property, retirement accounts, businesses, premarital assets, debt, maintenance, parenting arrangements, child support, valuation, discovery, and trial can add substantially more.
Montana equitably apportions property rather than applying an automatic community-property formula. These figures are planning ranges—not statewide averages, legal advice, or attorney quotes.
Local court charges are only the starting point in Montana; attorney involvement, property issues, mediation, and contested proceedings can have a much larger effect on the final budget. See our national guide to divorce costs for a deeper explanation of how those expenses fit together.
How Much Does It Cost to File for Divorce in Montana?
Dissolution cases are filed with the Clerk of District Court. The petition fee does not include every service, response, copy, mediation, or professional expense that may arise.

Montana Divorce Rules That Can Affect Cost
90 days of domicile before filing
At least one spouse generally must have been domiciled in Montana—or stationed there while in the armed services—for the 90 days preceding commencement of the case.
20-day minimum after service
A decree generally cannot be entered until at least 20 days have elapsed after service of the petition and summons. This is only a statutory minimum.
21 days to answer under current forms
The Judiciary's current dissolution flowchart gives the respondent 21 days after service to file an answer. The answer deadline and the decree minimum are different rules.
Automatic economic restraining order
Montana's dissolution summons includes an automatic economic restraining order intended to preserve financial stability while the case is pending.
Must You Prove Fault to Get Divorced in Montana?
Montana bases dissolution on an irretrievable breakdown of the marriage rather than requiring proof of adultery, abandonment, or another traditional marital offense.
When one spouse denies that the marriage is irretrievably broken, the court considers the circumstances and prospect of reconciliation and may continue the matter for a later hearing. Property, support, debt, and parenting disputes can proceed separately.
Mandatory Financial Disclosure in Montana
Montana's dissolution process requires financial disclosure. The statewide forms include a Financial Disclosure and Proposed Property Distribution, along with an Income and Expenses declaration that is exchanged between the spouses rather than filed publicly with the court.
Before requesting a final hearing, the filing party must submit a statement confirming compliance with disclosure requirements. Incomplete or disputed records can lead to discovery, tracing, subpoenas, valuation, and additional hearings.
- Income and recurring expenses
- Real estate and mortgage debt
- Bank and investment accounts
- Retirement benefits
- Business, ranch, and agricultural assets
- Other property and liabilities
Is Montana a 50/50 Divorce State?
Not automatically. Montana directs the court to equitably apportion property and assets belonging to either or both spouses, however and whenever acquired and regardless of title.
The statute's reach makes premarital, inherited, and gifted property relevant to the overall analysis. The court considers contributions to preservation or appreciation and the other statutory factors; equitable does not necessarily mean equal.
- Home equity and other real estate
- Ranch, agricultural, mineral, or water interests
- Bank and investment accounts
- Retirement benefits
- Business interests and operating debt
- Premarital, inherited, or gifted property
Why Can Montana Property Valuation Become Complicated?
Ranches, agricultural land, livestock, equipment, mineral or water interests, and closely held businesses can require specialized appraisal and income analysis.
Even when spouses agree that an asset belongs in the case, they may disagree about its value, debt, cash flow, premarital component, appreciation, or practical division. Those questions can add thousands of dollars in professional work.
How Can Children Affect a Montana Divorce?
A divorce involving minor children must address a parenting plan and child support. Montana Courts provides a separate dissolution packet with a Petition for Dissolution with Parenting Plan, a Proposed Parenting Plan, support materials, and related attachments.
Parenting disagreements can add interim orders, mediation, evaluations, discovery, hearings, and attorney preparation. Montana's 2026 Child Support Guidelines materials apply to current calculations.
- Proposed and final parenting plans
- Residential and decision-making schedules
- Child-support calculations
- Medical coverage
- Interim parenting orders
- Mediation, evaluations, or trial
Uncontested vs. Contested Divorce Costs in Montana
Agreed Montana divorce
- The spouses have resolved property, debt, maintenance, parenting, and support issues that apply.
- Joint and summary procedures may reduce service, motion practice, discovery, and hearings when the statutory requirements are met.
- A straightforward self-represented case can cost considerably less; Montana Courts provides complete dissolution packets.
Contested Montana divorce
- One or more significant property, support, or parenting issues remain unresolved.
- Temporary orders, discovery, mediation, appraisal, ranch or business valuation, depositions, experts, and trial preparation add cost.
- A substantial ranch, closely held business, prolonged parenting dispute, or trial can exceed the range.
Attorney time often becomes the largest variable when a Montana case remains disputed. Our divorce lawyer cost guide explains retainers, hourly billing, and why total legal fees vary.
What Can Make a Montana Divorce More Expensive?
The filing fee matters at the beginning, but unresolved property, support, and parenting questions usually determine the eventual total.
- Ranches, agricultural property, equipment, or livestock
- Premarital, inherited, or gifted-property analysis
- Home appraisal, equity, refinancing, or sale
- Retirement benefits and specialized division orders
- Parenting-plan and child-support disputes
- Maintenance, discovery, depositions, experts, or trial
