Getting Divorced in Montana: A Legal Guide

Montana divorce laws require at least one spouse to have been a resident for 90 days before filing, and follow equitable distribution principles for dividing marital property. The state prioritizes the best interests of children in custody decisions and offers both contested and uncontested divorce options with varying timelines and costs.

Filing for divorce without understanding Montana's specific legal requirements can lead to delays, unfavorable property settlements, or custody arrangements. Consulting with a family law attorney, even briefly, can help protect your rights and ensure proper procedure is followed.

Relevant Laws

Montana Dissolution of Marriage - No-Fault Divorce

Montana is a 'no-fault' divorce state, meaning you don't need to prove wrongdoing by either spouse to get divorced. You only need to show that the marriage is 'irretrievably broken' due to serious marital discord that adversely affects the attitude of one or both parties toward the marriage, or that there has been a separation of at least 180 days.

Montana Residency Requirements for Divorce

To file for divorce in Montana, at least one spouse must have been a resident of Montana for at least 90 days immediately before filing the petition. This residency requirement must be met before Montana courts have jurisdiction over your divorce case.

Montana Property Division - Equitable Distribution

Montana follows 'equitable distribution' principles when dividing marital property. This doesn't necessarily mean a 50/50 split, but rather a fair division based on factors including length of marriage, age and health of each spouse, occupation, income, vocational skills, employability, and contributions to the marriage including as a homemaker.

Montana Child Custody Determinations

Montana courts determine child custody (called 'parenting' in Montana) based on the best interests of the child. The court considers factors such as the child's wishes, each parent's wishes, the child's relationship with each parent, the child's adjustment to home/school/community, and any history of domestic violence.

Montana Child Support Guidelines

Montana uses specific guidelines to calculate child support based on both parents' incomes, the number of children, healthcare costs, childcare expenses, and other factors. These guidelines create a presumptive amount of support, though courts can deviate from the guidelines in appropriate circumstances.

Montana Spousal Maintenance (Alimony)

Montana courts may award spousal maintenance (alimony) if a spouse lacks sufficient property to provide for reasonable needs and is unable to be self-supporting through appropriate employment. The amount and duration depend on factors including the financial resources of each spouse, the standard of living established during the marriage, and the duration of the marriage.

Montana Divorce Waiting Period

Montana has a 20-day waiting period after filing before a divorce can be finalized. However, in practice, most divorces take longer due to court schedules and the time needed to resolve issues like property division, debt allocation, and parenting arrangements.

Regional Variances

Western Montana

Missoula County has a specialized Family Law Self-Help Center that provides additional resources for pro se litigants.

Flathead County requires additional financial disclosure forms beyond the standard Montana requirements. The county also has a unique parenting plan worksheet that must be completed when children are involved in a divorce case.

Central Montana

As the state capital's county, Lewis and Clark has more streamlined procedures for divorce cases. The county offers e-filing options not available in all Montana jurisdictions, and has specific local rules regarding temporary support hearings that differ from other counties.

Cascade County has implemented a specialized case management system for high-conflict divorce cases. The county also requires additional documentation for property division when real estate is involved, including specific appraisal requirements not mandated statewide.

Tribal Jurisdictions

Divorces involving tribal members on the Blackfeet Reservation may fall under tribal court jurisdiction rather than Montana state courts. The Blackfeet Tribal Court applies different laws and procedures than state courts, particularly regarding child custody and property division for trust lands.

The Crow Tribal Court has jurisdiction over divorces between tribal members residing on the reservation. Their procedures differ significantly from Montana state law, with greater emphasis on extended family involvement in custody decisions and different approaches to property division.

Yes, Montana is a 'no-fault' divorce state. You can file for divorce based on the grounds that the marriage is 'irretrievably broken,' which means there is no reasonable prospect of reconciliation. You don't need to prove that either spouse was at fault for the breakdown of the marriage.

Montana follows 'equitable distribution' laws, which means marital property is divided fairly but not necessarily equally. The court considers factors such as the duration of the marriage, each spouse's economic circumstances, contributions to the marriage (including homemaking), and each spouse's age and health when determining a fair division.

Montana courts make custody decisions based on the 'best interests of the child.' The court considers factors such as the child's wishes (if they're mature enough), each parent's wishes, the child's relationship with each parent, the child's adjustment to home and community, and the mental and physical health of all individuals involved. Montana courts generally favor arrangements that allow children to have meaningful relationships with both parents.

Montana uses the 'Income Shares Model' to calculate child support, which considers both parents' incomes and the number of children. The Montana Child Support Guidelines provide a formula that accounts for factors such as healthcare costs, childcare expenses, and parenting time. The Montana Child Support Enforcement Division provides resources to help calculate estimated payments.

While you're not legally required to have a lawyer, it's often advisable, especially if your case involves children, significant assets, or disputes. If your divorce is uncontested and relatively simple, you might be able to use the self-help resources provided by the Montana Judicial Branch, which offers forms and guidance for self-represented litigants.

A parenting plan is a detailed written agreement that outlines how parents will share the responsibilities of raising their children after divorce. In Montana, a parenting plan is required in all cases involving children.

The court must approve the plan, ensuring it serves the best interests of the children.

Yes, certain aspects of a divorce decree can be modified in Montana if there has been a substantial change in circumstances.
