Family Law in Montana — what to do right now

Right now, do three things. First, write down dates: when you separated, when (or if) the other side was served, and any court dates already set. Second, do not move money, hide assets, or take the kids out of state to gain an advantage — Montana courts notice, and it can backfire in your parenting plan. Third, if you're in danger, you can ask any District, Justice, City or Municipal Court for a temporary order of protection the same day. Then call 1-844-690-0555 free to understand your options before you file or respond.


The law in Montana: Family Law

Montana calls divorce a 'dissolution of marriage,' and it is purely no-fault. Under MCA § 40-4-104, the only ground is that the marriage is 'irretrievably broken' — shown either by living separate and apart for more than 180 days, or by serious marital discord with no reasonable prospect of reconciliation. You must have lived in Montana at least 90 days before filing. Old fault-style defenses like adultery, condonation or recrimination are abolished by MCA § 40-4-105, so cheating or blame won't change the divorce itself. Dissolutions, parenting plans, child support and protection orders are all heard in Montana's District Courts (22 judicial districts across 56 counties), with appeals only to the seven-justice Montana Supreme Court in Helena.

Montana is an equitable-distribution state, not a community-property (50/50) state. Under MCA § 40-4-202 the court divides property 'equitably' — fairly, not necessarily equally — 'without regard to marital misconduct.' The catch that blindsides people: Montana courts can reach property 'however and whenever acquired,' which the Montana Supreme Court confirmed in In re Marriage of Funk (2012) to include assets you owned before the marriage and even inheritances. There is no automatic 'that's mine, I had it first' rule here. The judge weighs the length of the marriage, each spouse's age, health and earning ability, who cared for the kids and home, and the value of each estate.

Montana law dropped the words 'custody' and 'visitation.' Instead, parents file a parenting plan, and the court decides it under the best-interest factors in MCA § 40-4-212 — the child's relationship with each parent, adjustment to home, school and community, everyone's mental and physical health, and any history of abuse. MCA § 40-4-234 requires each parent to submit a proposed final parenting plan in good faith, covering the residential schedule, holidays, and who makes major decisions. Frequent, continuing contact with both parents is presumed to be in the child's interest unless contact would be harmful.

Montana sets child support under MCA § 40-4-204 and the guideline rules in ARM 37.62.106, using an 'Income Shares' model: both parents' incomes are combined, a basic support figure is set, and each parent pays a proportional share, adjusted for parenting time and costs like health insurance and childcare. The Montana Department of Public Health and Human Services Child Support Enforcement Division (CSED) can establish, modify and enforce orders — including wage withholding, license suspension and intercepting tax refunds — even if you never go to court.

Key Montana Statutes

  • MCA § 40-4-104 — dissolution; 'irretrievably broken' is the only ground; 90-day residency
  • MCA § 40-4-105 — procedure; decree may not be entered until 21 days after service; fault defenses abolished
  • MCA § 40-4-202 — equitable division of property 'however and whenever acquired'
  • MCA § 40-4-212 & § 40-4-234 — best-interest factors and final parenting-plan criteria
  • MCA § 40-4-204 — child support; Income Shares guidelines (ARM 37.62.106)
  • MCA Title 40, Ch. 15 — orders of protection (§ 40-15-201 temporary; § 40-15-202 hearing)

Courts & Agencies

  • Montana District Courts — divorce, parenting plans, support, larger civil (22 judicial districts)
  • Justice, City & Municipal Courts — can issue temporary orders of protection (MCA § 40-15-301)
  • Montana Supreme Court (Helena) — the only appellate court, 7 justices
  • DPHHS Child Support Enforcement Division (CSED) — establishes & enforces support
  • Montana Judicial Branch Self-Help Law Centers — forms and guidance for self-represented parties

Deadlines & Outcomes

  • 90 days — Montana residency required before you can file for dissolution
  • 21 days after service — earliest a dissolution decree can be entered (MCA § 40-4-105)
  • 21 days — a served respondent's window to file a verified response
  • 20 days — a temporary order of protection hearing must be held within 20 days (MCA § 40-15-201)
  • PFMA: up to 1 year in jail for a 1st/2nd conviction; 3rd is a felony (MCA § 45-5-206)

In Montana, the home you had before the wedding may still be on the table.

People moving to Montana — or marrying later in life — assume the house, the ranch, the retirement account or the inheritance they brought into the marriage is automatically safe. It isn't. Under MCA § 40-4-202 and the Montana Supreme Court's decision in In re Marriage of Funk (2012), a Montana judge can equitably divide property 'however and whenever acquired,' including premarital and inherited assets. Whether your separate property gets pulled in turns on facts like how long the marriage lasted and how the asset was used and maintained — not on a tidy 'I owned it first' rule. That single difference reshapes who walks away with what. Before you assume anything is protected, call 1-844-690-0555 free to understand how Montana would treat your property.


Likely outcomes & penalties

Every family case turns on its own facts, but here are realistic ranges Montanans see. These are general information, not a prediction about your case.
Uncontested dissolution timeline
No decree can be entered until at least 21 days after the other spouse is served (MCA § 40-4-105); fully agreed cases often finalize in roughly 1–3 months, contested ones much longer.
Property split
Equitable, not automatic 50/50 — and under In re Marriage of Funk premarital and inherited assets can be divided. Outcomes range from near-equal to heavily weighted, depending on the statutory factors.
Child support
Set by the Income Shares guideline (ARM 37.62.106) from both parents' combined income and parenting time; CSED can enforce via wage withholding, license suspension and tax-refund intercept.
Partner/Family Member Assault (PFMA)
1st or 2nd conviction is a misdemeanor up to 1 year in jail (1st: minimum 24 hours, $100 fine); 3rd or later is a felony with at least 30 days and up to 5 years (MCA § 45-5-206).

Mistakes to avoid

⚠️
Assuming the house, ranch or inheritance you brought into the marriage is automatically 'yours' — Montana can divide property however and whenever acquired (MCA § 40-4-202).
⚠️
Thinking adultery or who 'caused' the breakup changes the divorce or property split — Montana is no-fault and divides property without regard to marital misconduct.
⚠️
Filing before you've lived in Montana 90 days, then having the dissolution stall or get dismissed for failing the residency requirement.
⚠️
Treating Montana like a 'custody' state — you must submit a good-faith parenting plan under MCA § 40-4-234, and judges notice parents who use the kids as leverage.
⚠️
Ignoring CSED — a child-support order can be established, modified and enforced administratively, with wage withholding and license suspension, even without a courtroom.
⚠️
Letting a temporary order of protection lapse by missing the hearing that must be held within 20 days (MCA § 40-15-201).

FAQ — Family Law in Montana

Do I need a 'reason' to divorce in Montana?

No. Montana is a pure no-fault state. The only ground under MCA § 40-4-104 is that the marriage is 'irretrievably broken,' shown by living apart more than 180 days or by serious marital discord with no reasonable prospect of reconciliation. Adultery or blame won't change the divorce or the property split. To understand how this applies to you, call 1-844-690-0555 free, any time.

How long do I have to live in Montana before I can file?

At least 90 days. MCA § 40-4-104 requires you (or your spouse) to have been a Montana resident for 90 days before filing for dissolution. File too early and your case can stall or be dismissed. Not sure whether you qualify yet? Call 1-844-690-0555 free for clear information before you file.

How fast can a Montana divorce be final?

Even with full agreement, a decree can't be entered until at least 21 days after your spouse is served (MCA § 40-4-105). Fully uncontested cases often wrap in roughly one to three months; contested ones take much longer. The 21-day clock starts on service, not on filing. For a realistic timeline for your situation, call 1-844-690-0555 free, 24/7.

Is the property I owned before marriage safe in Montana?

Not automatically. Under MCA § 40-4-202 and In re Marriage of Funk (2012), a Montana judge can equitably divide property 'however and whenever acquired,' including premarital and inherited assets. Whether yours gets pulled in depends on the facts. Before you assume anything is protected, call 1-844-690-0555 free to understand how Montana would treat it.

Does Montana split everything 50/50?

No. Montana is an equitable-distribution state, not a community-property state. MCA § 40-4-202 directs the court to divide property 'equitably' — fairly, weighing the length of the marriage, each spouse's circumstances, and contributions including homemaking — which can be far from an even split. To learn what 'equitable' might mean for you, call 1-844-690-0555 free.

Montana keeps saying 'parenting plan' — what about custody?

Montana law no longer uses 'custody' or 'visitation.' Instead, each parent submits a proposed parenting plan, and the court decides it under the best-interest factors in MCA § 40-4-212 and the criteria in MCA § 40-4-234. The plan covers the residential schedule, holidays and decision-making. For help understanding what a workable plan looks like, call 1-844-690-0555 free, 24/7.

How is child support calculated in Montana?

Montana uses an 'Income Shares' model under MCA § 40-4-204 and ARM 37.62.106: both parents' incomes are combined, a basic obligation is set, and each parent pays a proportional share adjusted for parenting time and costs like health insurance and childcare. The CSED can also establish and enforce orders. To see how the guideline applies to your numbers, call 1-844-690-0555 free.

Can child support be enforced without going to court?

Yes. Montana's DPHHS Child Support Enforcement Division (CSED) can establish, modify and enforce support administratively — including wage withholding, suspending licenses and intercepting tax refunds — without a courtroom hearing. If you're dealing with CSED, call 1-844-690-0555 free to understand your rights and deadlines.

How do I get a protection order in Montana, and how fast?

You can file a sworn petition for a temporary order of protection in a District, Justice, City or Municipal Court (MCA § 40-15-301), and a judge can issue one the same day if you're in reasonable apprehension of harm. A full hearing must be held within 20 days (MCA § 40-15-201). If you're afraid, call 1-844-690-0555 free, day or night, to understand the steps.

Who can get an order of protection in Montana?

Victims of partner or family member assault, sexual assault, and stalking. For partner/family-member situations there must be that relationship, but for stalking no family relationship is required (MCA Title 40, Ch. 15). There's no residency requirement and an order is effective statewide. To find out if you qualify, call 1-844-690-0555 free, 24/7.

What happens to someone charged with partner or family member assault?

Under MCA § 45-5-206, a first or second PFMA conviction is a misdemeanor punishable by up to one year in jail (a first carries a minimum 24 hours and $100 fine), and a third or later conviction is a felony with at least 30 days and up to five years. Courts often also impose no-contact conditions. For information about a PFMA matter, call 1-844-690-0555 free.
