The fastest divorce in Montana takes about 20 to 30 days through summary dissolution under Mont. Code Ann. § 40-4-130, which requires no minor children, under $50,000 in marital assets, and a signed settlement. A standard uncontested dissolution finalizes in roughly 60 to 90 days once you meet the 90-day residency rule.

How Fast Can You Get a Divorce in Montana?
The quickest way to get divorced in Montana is summary dissolution, which can conclude in 20 to 30 days after both spouses file a joint petition under Mont. Code Ann. § 40-4-130. A standard uncontested divorce typically finalizes in 60 to 90 days, while a contested divorce averages 8 to 18 months. Montana imposes no mandatory cooling-off period for ordinary uncontested cases, so timing depends mostly on paperwork, service, and the court's calendar.
Speed in a Montana divorce is driven by three variables: your grounds, whether both spouses agree, and how quickly the respondent is served and answers. Because Montana is a pure no-fault state, you never have to prove wrongdoing, which removes months of evidence-gathering that fault states require. The single legal ground is irretrievable breakdown of the marriage, established either by a 180-day separation or by a finding of serious marital discord. A cooperative spouse who signs a waiver of service and a marital settlement agreement can compress a Montana divorce to its statutory minimum. If you want a step-by-step plan tailored to your situation, build a personalized divorce roadmap before you file.
Montana Residency Requirements for a Fast Divorce
To file for divorce in Montana, at least one spouse must have been a resident of the state for 90 days immediately before filing, as required by Mont. Code Ann. § 40-4-104. This 90-day rule is a jurisdictional prerequisite, meaning the court cannot grant a dissolution until it is satisfied. Active-duty military members stationed in Montana for 90 days meet the requirement even if their legal domicile is another state.
The residency clock is the single biggest structural limit on how fast you can file. You cannot shorten the 90 days, so anyone planning a fast Montana divorce should count that period from the day they establish residency, not from the day they decide to divorce. Proof of residency includes a Montana driver's license, voter registration, a signed lease, utility bills, or property tax records showing a Montana address. File your Petition for Dissolution of Marriage in the district court of the county where either spouse lives. If minor children are involved, the children generally must have lived in Montana for at least 6 consecutive months to give the court custody jurisdiction under the Uniform Child Custody Jurisdiction and Enforcement Act. Meeting these thresholds cleanly at the outset prevents a dismissal that would reset your timeline entirely.
Montana's No-Fault Grounds: The Key to Speed
Montana recognizes only one ground for divorce: irretrievable breakdown of the marriage, defined in Mont. Code Ann. § 40-4-107. The court finds irretrievable breakdown when the spouses have lived separate and apart for more than 180 days before filing, or when there is serious marital discord that adversely affects one or both spouses' attitude toward the marriage. Because no fault must be proven, uncontested cases move quickly.
The serious-marital-discord path is what makes a fast Montana divorce possible without a long separation. You do not have to wait 180 days apart if you can allege ongoing discord with no reasonable prospect of reconciliation. Montana abolished traditional fault defenses like condonation and recrimination under Mont. Code Ann. § 40-4-105, so a respondent cannot drag out the case by contesting the reason for the divorce itself. There is one narrow delay: if one spouse denies that the marriage is irretrievably broken, the court may continue the matter for up to 60 days and may recommend counseling. In practice, when both spouses agree the marriage is over, the court accepts the irretrievable-breakdown finding at the final hearing and no cooling-off period applies. This no-fault structure is the core reason Montana ranks among the faster states for a cooperative, quick divorce.
Summary Dissolution: Montana's Fastest Divorce Option
Summary dissolution is the fastest divorce process in Montana, allowing a final judgment as soon as 20 days after both spouses jointly file, under Mont. Code Ann. § 40-4-133. It is reserved for simple, fully agreed cases with no minor children, marital assets under $50,000, and unsecured debts under $20,000. Both spouses must sign a settlement dividing everything and waive their right to appeal.
To qualify for summary dissolution under Mont. Code Ann. § 40-4-130, you must meet every one of these conditions:
- No children were born of the relationship, and the wife is not pregnant.
- Neither spouse holds an interest in real property (no house or land).
- Unsecured obligations incurred since the marriage do not exceed $20,000.
- The total fair market value of marital assets, excluding secured debts, is less than $50,000.
- Both spouses have signed an agreement dividing all assets and liabilities and have executed any titles or bills of sale needed to carry it out.
- Both spouses irrevocably waive their rights to appeal and to move for a new trial.
- Both spouses confirm they have read and understood the official summary dissolution brochure.
After the joint petition is filed, the court sets a hearing no sooner than 20 days out. Both spouses must appear, and if the judge confirms the statutory conditions still exist, the court enters the final decree that day. This procedure eliminates the service-and-answer wait that a one-sided filing requires, which is why summary dissolution consistently produces the quickest divorce in Montana. Short, low-asset marriages without children are the ideal candidates.
Step-by-Step: The Fastest Path to a Montana Divorce
The fastest standard divorce in Montana follows six steps and can finish in 60 to 90 days when both spouses cooperate. The timeline hinges on how quickly the respondent is served and files an answer, and whether you present a signed settlement to the court. Filing jointly or securing a signed waiver of service can shave weeks off the process.
- Confirm eligibility. Verify 90-day residency under Mont. Code Ann. § 40-4-104 and decide whether you qualify for summary dissolution.
- Prepare the petition. Complete the Petition for Dissolution of Marriage and, in agreed cases, a marital settlement agreement covering property, debts, and any support.
- File with the district court. Submit your paperwork in the county where either spouse lives and pay the roughly $250 in filing and judgment fees, or request a fee waiver.
- Serve the other spouse. Use the sheriff, a private process server, or a signed acceptance of service. A voluntary acceptance is the fastest and cheapest route.
- Complete the response window. In a contested filing the respondent has 21 days to answer after service; if both spouses sign the paperwork, this window collapses.
- Attend the final hearing. Once the court reviews the settlement and confirms irretrievable breakdown, the judge signs the Decree of Dissolution and the marriage legally ends.
Organizing your financial documents early is the single most effective way to keep this timeline tight. If children are involved, run the numbers with the Montana child support calculator before your hearing so the parenting and support terms are ready to submit. Disagreements over even one asset can push a case from the uncontested track onto the contested track, adding months.
Montana Divorce Filing Fees and Costs
The court filing fee to start a divorce in Montana is a $200 filing fee plus a $50 judgment fee, totaling approximately $250 under Mont. Code Ann. § 25-1-201. If the respondent files a formal answer, an additional fee of roughly $70 applies. As of August 2026, these amounts apply across Montana's 56 counties. Verify the exact figure with your local clerk of district court.
Beyond the filing fee, budget for a handful of predictable costs. Service of process through a private server runs $50 to $100, while the county sheriff typically charges less. Certified copies of your final decree cost about $3 to $5 each, and document certification runs roughly $2 per page. Spouses who cannot afford these costs may request a fee waiver if household income is at or below 125% of the federal poverty guidelines, which removes the filing fee entirely. An uncontested summary dissolution or agreed divorce that avoids attorneys can cost as little as $250 to $400 all-in. A contested Montana divorce, by contrast, commonly runs $7,000 to $20,000 or more once attorney time is included. For a personalized estimate, use the divorce cost estimator to model your likely range before you commit to a strategy.
What Slows a Montana Divorce Down
The most common causes of delay in a Montana divorce are disputes over property, parenting, or support, plus difficulty serving the other spouse. A contested case averages 8 to 18 months, compared with 60 to 90 days for an uncontested one. A spouse who evades service, refuses to sign, or denies that the marriage is irretrievably broken can trigger a court continuance of up to 60 days.
Several specific bottlenecks are worth planning around. First, contested custody or parenting-plan disputes require a parenting plan, mediation, and sometimes a guardian ad litem, each adding weeks. Second, complex or high-value assets, including businesses, retirement accounts, or real property, force valuation and disclosure that a summary dissolution simply does not allow. Third, a respondent who cannot be located may require service by publication, which itself takes 30 days or more. Fourth, if either spouse contests the irretrievable-breakdown finding, Mont. Code Ann. § 40-4-107 lets the judge pause the case for reconciliation counseling. Avoiding these traps is largely within your control: reach a written agreement before filing, disclose finances fully, and keep the case on the uncontested track. When conflict is unavoidable, it is usually faster and cheaper to connect with a Montana divorce attorney early than to unwind a stalled case later.
How Property Division Affects Your Timeline
Montana divides marital property by equitable distribution under Mont. Code Ann. § 40-4-202, meaning the court aims for a fair split that is not necessarily 50/50. Montana is not a community property state; instead, judges weigh the marriage length, each spouse's contributions, and future earning capacity. Because the court must apportion everything, unresolved property disputes are the leading reason a fast divorce turns slow.
Montana uses an all-property model: the court can distribute both marital and separately owned assets, considering how each was acquired and preserved. Factors under the statute include the duration of the marriage, each spouse's age, health, occupation, and employability, the opportunity to acquire future assets, and contributions as a homemaker. Importantly, Montana courts divide property without regard to marital misconduct, so an affair does not shift the split. Understanding how equitable distribution works helps you build a settlement the judge will approve quickly. The fastest path is a written marital settlement agreement that divides every asset and debt, because it lets the court adopt your terms rather than conduct its own valuation and trial. When spouses hand the judge a complete, signed division, the property phase adds days rather than months to the case.
