A divorce without children in Montana costs $250 to file, requires one spouse to be domiciled in the state for 90 days, and can be finalized as quickly as 20-30 days after service in uncontested cases. Montana is a no-fault, equitable-distribution state under Montana Code Annotated Title 40, Chapter 4, so the only ground is that the marriage is irretrievably broken.
Getting divorced with no children in Montana is the simplest version of dissolution the state offers. Without a parenting plan, child support worksheet, or six-month child-residency requirement to satisfy, a childless couple sidesteps the most contested and time-consuming parts of family law. This guide explains every step of the no kids divorce process in Montana — from the 90-day residency rule under Mont. Code Ann. § 40-4-104 to how the court equitably apportions your marital estate under Mont. Code Ann. § 40-4-202.

What Makes a Divorce Without Children Simpler in Montana?
A divorce without children in Montana eliminates roughly half the legal machinery of a typical dissolution: no parenting plan, no child support calculation, and no six-month child-residency requirement under Mont. Code Ann. § 40-4-211. This means a childless couple who agree on property and debt can often finalize in 20 to 30 days after service, compared to several months for contested custody cases.
When a Montana marriage produces no minor children, the court has only two categories of decisions to make: dividing the marital estate and deciding whether either spouse receives maintenance (alimony). There is no parenting plan to negotiate, no child support to calculate under Montana's income-shares model, and no guardian ad litem to appoint. Montana law still requires the same jurisdictional foundation — one spouse domiciled in the state for 90 days — but the childless divorce process removes the single largest source of litigation in family court. Couples who use the state's dissolution-without-children forms (Montana Judicial Branch Form 3-221) frequently complete the entire process without ever appearing before a judge, provided both spouses sign the paperwork and no financial disputes arise.
Do I Meet the Residency Requirement to File in Montana?
To file for divorce in Montana, at least one spouse must be domiciled in the state for a minimum of 90 consecutive days immediately before filing the petition, under Mont. Code Ann. § 40-4-104. This requirement is jurisdictional and cannot be waived — if neither spouse meets the 90-day threshold, the court must dismiss the case regardless of how the parties feel.
The residency rule is straightforward to calculate. If you established domicile in Montana on January 1, you become eligible to file on April 1. Military service members stationed in Montana for 90 days also satisfy this jurisdictional prerequisite, even if Montana is not their legal home of record. Domicile means more than physical presence: it requires living in Montana with the intent to remain, which courts infer from evidence such as a Montana driver's license, voter registration, vehicle registration, and a permanent address. Because this simple divorce no children requirement is jurisdictional, the District Court verifies it before proceeding, and a petition filed before the 90th day will be dismissed. There is no exception, hardship waiver, or shortcut. A spouse who recently relocated must simply wait until day 90 to file the Petition for Dissolution of Marriage in the county where either party resides.
What Are the Grounds for Divorce in Montana?
Montana is exclusively a no-fault divorce state. The only ground for dissolution is that the marriage is irretrievably broken, established under Mont. Code Ann. § 40-4-104. Neither spouse must prove adultery, cruelty, or abandonment, and marital misconduct plays no role in whether the divorce is granted.
To establish that a marriage is irretrievably broken, Montana law requires evidence of one of two conditions. Either the parties have lived separate and apart for more than 180 days preceding the filing, or there is serious marital discord that adversely affects the attitude of one or both spouses toward the marriage. In practice, most petitioners simply state under oath that serious marital discord exists, which satisfies the statute without a 180-day separation. If one spouse denies the marriage is irretrievably broken, the court may order a continuance of up to 60 days and may recommend counseling under Mont. Code Ann. § 40-4-107. This rarely prevents the divorce — after the continuance, if either spouse still asserts the marriage is broken, the court proceeds. Because Montana excludes fault from the grounds analysis, a no dependents divorce here focuses entirely on the practical questions of property, debt, and support rather than blame.
How Much Does a Divorce Without Children Cost in Montana?
The filing fee for a divorce in Montana is $250, comprising a $200 filing fee and a $50 judgment fee under Mont. Code Ann. § 25-1-201. A responding spouse who files an answer pays an additional $70, bringing combined court costs to roughly $320 when both parties participate. These fees apply uniformly across Montana's 56 counties.
Beyond the mandatory filing fee, several additional costs may apply. Service of process by a private process server ranges from $50 to $100, though the county sheriff's office typically charges less. Certified copies of the final Decree of Dissolution cost $3 to $5 each, and document certification runs approximately $2 per page. A childless, uncontested divorce where both spouses agree on all terms and use the free Montana Judicial Branch forms can be completed for the base $250 filing fee alone. If either spouse cannot afford the court costs, Montana allows a fee waiver: file a Statement of Inability to Pay Court Costs and Fees with your initial documents, and a District Court Judge must approve it before the case proceeds without payment. As of January 2026, verify current fees with your local Clerk of District Court, since counties may assess nominal charges for copies or certification.

| Respondent answer fee | $70 | Only if respondent files answer |
| Private process server | $50-$100 | Sheriff often charges less |

How Is Property Divided in a Montana Divorce With No Children?
Montana is an equitable-distribution state that divides the marital estate fairly, though not necessarily equally, under Mont. Code Ann. § 40-4-202. Uniquely, Montana courts may divide all property owned by either spouse — including premarital assets, inheritances, and gifts — regardless of when or how it was acquired, because the state uses an "all-property" model rather than separating marital from non-marital assets.
Montana courts presume spouses have common ownership in all property and assets of the marital estate, treating the marriage as an economic partnership. When apportioning property, the court considers the duration of the marriage, each spouse's age and health, occupation and employability, income and assets, liabilities, and each spouse's contributions — including as a homemaker. Marital misconduct such as infidelity is excluded from the property analysis, though the economic consequences of misconduct — like a spouse who dissipated assets through gambling or spending on an affair — may be weighed. For premarital, gifted, or inherited property, the court applies additional analysis: a $500,000 inheritance received one month before filing typically stays with the inheriting spouse, while retirement accounts built over a 20-year marriage are usually divided. When a petition is filed, an automatic economic restraining order is served with the summons, immediately prohibiting both parties from transferring, hiding, or encumbering marital property without written consent or court permission. Without children complicating the estate, a childless couple often reaches a written settlement dividing assets and debts that the court simply approves.
How Long Does a No-Kids Divorce Take in Montana?
An uncontested divorce without children in Montana can be finalized in as little as 20 to 30 days after the respondent is served, once the mandatory 21-day waiting period under Mont. Code Ann. § 40-4-105 has passed. Contested divorces involving property disputes typically take 6 to 12 months, but the absence of custody litigation removes the single largest source of delay.
The timeline begins when the petitioner files and the respondent is served with the Petition and Summons. The respondent then has 21 days to file a verified Response. This 21-day period is both the response deadline and the minimum waiting period before the court can enter a final decree. In an uncontested no dependents divorce where both spouses sign a joint petition or a marital settlement agreement, the court can enter the Decree of Dissolution shortly after the waiting period expires, often without a hearing. If the respondent fails to answer within 21 days, the petitioner may request a default judgment. Contested cases move slower because they require discovery, disclosure of financial information, possible mediation, and potentially a trial. Because a childless divorce carries no parenting plan or child support worksheet, couples who agree on dividing their marital estate frequently reach the fastest possible resolution Montana law allows.
Montana Divorce Timeline: Contested vs. Uncontested
| Stage | Uncontested (No Children) | Contested |
|---|---|---|
| Residency before filing | 90 days | 90 days |
| Waiting period after service | 21 days | 21 days |
| Response deadline | 21 days | 21 days |
| Typical time to final decree | 20-30 days | 6-12 months |
| Court hearing required | Often none | Usually yes |
What Are the Steps to File for Divorce Without Children in Montana?
Filing a childless divorce in Montana follows six core steps, and an uncontested case using the free Montana Judicial Branch forms can move from petition to decree in about 20 to 30 days after service. The process starts with confirming the 90-day residency requirement under Mont. Code Ann. § 40-4-104 and ends with the judge signing the Decree of Dissolution.
The streamlined no kids divorce process in Montana proceeds as follows:
- Confirm eligibility: verify at least one spouse has been domiciled in Montana for 90 days.
- Complete the forms: use the Montana Judicial Branch "Dissolution Without Children" packet (Form 3-221), including the Petition for Dissolution of Marriage.
- File with the Clerk of District Court: submit the petition in the county where either spouse resides and pay the $250 fee (or file a fee-waiver request).
- Serve your spouse: have the respondent served with the Petition and Summons by sheriff or private process server; a cooperative spouse may sign an Acknowledgment of Service.
- Complete financial disclosures and a settlement agreement: divide property and debts in writing, since Montana requires equitable apportionment under Mont. Code Ann. § 40-4-202.
- Obtain the decree: after the 21-day waiting period, submit the proposed Decree of Dissolution for the judge's signature.
Because no parenting plan is required, spouses who cooperate can often complete every step by mail or e-filing without a courtroom appearance.
Will I Have to Pay Spousal Maintenance in a Montana Divorce?
Spousal maintenance (alimony) is not automatic in Montana and is awarded only when a spouse lacks sufficient property to meet reasonable needs and cannot support themselves through employment, under Mont. Code Ann. § 40-4-203. In a short, childless marriage where both spouses are employed, maintenance is uncommon because each party can typically be self-supporting.
Montana courts apply a two-part threshold before considering maintenance. First, the requesting spouse must lack sufficient property, including their share of the marital estate, to provide for reasonable needs. Second, that spouse must be unable to be self-supporting through appropriate employment. Only if both conditions are met does the court set an amount and duration by weighing the requesting spouse's financial resources, the time needed to acquire education or training, the standard of living during the marriage, the marriage's duration, and the paying spouse's ability to meet their own needs while paying support. In a no dependents divorce, maintenance decisions are simpler because there is no child support obligation competing for the same income. Many childless couples resolve maintenance by written agreement — either waiving it entirely or agreeing to a fixed sum — which the court incorporates into the Decree of Dissolution. Marital misconduct does not affect maintenance under Montana's no-fault framework.
