Great Falls Divorce Lawyers

Great Falls sits in Cascade County, and every divorce filed by a Great Falls resident moves through the Eighth Judicial District Court inside the historic Cascade County Courthouse at 415 2nd Avenue North. You will not drive to Helena or Bozeman; you file locally with the Clerk of District Court in Room 200, two blocks from Central Avenue and the Civic Center downtown. Montana is a no-fault, equitable-distribution state, so the court divides property fairly rather than awarding fault-based punishment. Below is the local roadmap, the verified fees, the courthouse logistics, and the Montana statutes that control your case.

Great Falls Divorce: Key Facts (2026)

The table below summarizes the local logistics for a Cascade County dissolution. Every dollar figure and statute reflects current Montana Code Annotated provisions verified in 2026. A standard contested case touches all of these checkpoints; an uncontested case still requires the filing fee, the residency proof, and a judge's signature on the final decree.

How do I file for divorce in Great Falls, Montana?

To file for divorce in Great Falls, complete a Petition for Dissolution of Marriage and submit it to the Cascade County Clerk of District Court at 415 2nd Avenue North, Room 200, with the $250 filing fee. Montana is no-fault under MCA § 40-4-104, so you only assert the marriage is irretrievably broken.

The practical sequence in Great Falls is straightforward. First, confirm the 90-day residency requirement is met. Second, prepare the petition; if you have minor children, you must also file a proposed Parenting Plan. Third, file in person at the courthouse or, where available, through the Montana District Court e-filing system. Fourth, serve your spouse, who then has 20 days to respond under MCA § 40-4-105. The Clerk of District Court files roughly 4,800 new cases annually across all case types, and domestic-relations matters like dissolutions are among the most common. If you cannot afford the $250, ask the Clerk for a Statement of Inability to Pay Court Costs and Fees, which a district judge must approve before your petition is accepted.

Where do I file for divorce in Great Falls? (which courthouse)

Great Falls residents file at the Cascade County Courthouse, 415 2nd Avenue North, Room 200, Great Falls, MT 59401, home to the Eighth Judicial District Court. The Clerk of District Court keeps all dissolution records and is open Monday through Friday, 8:00 AM to 5:00 PM, excluding holidays. The phone number is (406) 454-6780.

The courthouse, built between 1901 and 1903, anchors the downtown civic district near the Civic Center and Gibson Park, a short walk from Central Avenue. Parking is available on surrounding streets and nearby public lots. When you arrive, go to Room 200 for the Clerk of District Court, where staff accept filings, assign your case number, and route the matter to one of the district judges. They cannot give legal advice, but they can confirm which forms a dissolution requires. You can also review case status online through the Montana District Court Public Access Portal at dcportal.pubcourts.mt.gov by selecting Cascade District Court. Bring two copies of every document plus the original, since you will need stamped copies for service.

How much does a divorce lawyer cost in Great Falls?

A Great Falls divorce lawyer typically charges $200 to $350 per hour, and a fully contested Cascade County divorce commonly runs $7,000 to $15,000 or more once you add expert witnesses, depositions, and trial time. An uncontested divorce with a flat-fee attorney often costs $1,500 to $3,000 plus the $250 court filing fee.

The single largest cost driver is conflict. If you and your spouse agree on property, support, and parenting, you keep attorney hours low and may finish for a few thousand dollars total. Contested custody disputes or business and ranch valuations push costs higher because they require appraisers and forensic accountants. Additional Cascade County costs include service of process ($50 to $100 for a private process server, less through the sheriff), certified copies of the decree ($3 to $5 each), and document certification near $2 per page. Many Great Falls firms offer flat-fee uncontested packages and free or low-cost initial consultations, so ask about fee structure before you retain counsel.

How long does a divorce take in Great Falls?

An uncontested divorce in Great Falls often finalizes in three to four months once the 20-day response window closes and a judge signs the decree. A contested Cascade County divorce involving custody or significant property typically takes 8 to 18 months because of discovery, mediation, and the Eighth Judicial District Court's hearing calendar.

Montana does not impose a long mandatory cooling-off period for an agreed dissolution, so timing depends mostly on cooperation and court scheduling. After you file and serve, your spouse has 20 days to answer under MCA § 40-4-105. If both parties sign a marital settlement agreement and proposed parenting plan, a judge can enter the decree quickly. When the case is contested, the court may order mediation, set interim parenting and support orders under MCA § 40-4-213, and schedule a final hearing months out. Cases with minor children require those children to have lived in Montana six months before the court takes jurisdiction over parenting decisions.

What are the residency requirements to file in Cascade County?

To file in Cascade County, at least one spouse must have been domiciled in Montana for 90 days immediately before filing, as required by MCA § 40-4-104. Military members stationed in Montana for 90 days also qualify. There is no separate county-residency minimum beyond the statewide 90-day rule.

Domicile means Montana is your true, fixed home, not a temporary stay. If you moved to Great Falls from out of state on January 1, you can file on April 1 or later. The 90-day figure is a residency rule, not a post-filing waiting period; people often confuse the two. If your case involves children under 18, an additional rule applies: the children generally must have lived in Montana for at least six months before a court can decide parenting matters, satisfying the Uniform Child Custody Jurisdiction and Enforcement Act. Active-duty service members at Malmstrom Air Force Base, just east of Great Falls, frequently rely on the military-presence provision in the statute to establish eligibility.

How is property divided in a Great Falls divorce?

Montana courts divide marital property by equitable distribution under MCA § 40-4-202, meaning a fair but not necessarily equal split. Montana includes nearly all assets in the marital estate regardless of how or when acquired, so inheritances, premarital property, and gifts can all be divided based on statutory factors.

Unlike most equitable-distribution states, Montana does not shield a separate-property category from division. The Montana Supreme Court confirmed this in In re Marriage of Funk (2012), holding that inherited assets worth hundreds of thousands of dollars could be apportioned between spouses. Judges weigh marriage length, each spouse's age, health, income, and employability, the value of each estate, custodial arrangements for children, and the nonmonetary contributions of a homemaker. Marital misconduct such as infidelity is excluded from the analysis. The court also presumes spouses share common ownership of the marital estate, so a stay-at-home parent in Great Falls retains a real claim to assets titled solely in the working spouse's name. Spousal maintenance, when awarded, follows a separate needs-and-ability standard.

How does child custody work in Great Falls?

Montana uses parenting plans rather than custody labels, and the Eighth Judicial District Court decides parenting under the best-interest standard in MCA § 40-4-212. Judges presume frequent and continuing contact with both parents serves the child unless evidence of abuse or chemical dependency shows otherwise.

When you file in Cascade County with minor children, you submit a proposed parenting plan describing residential schedules, decision-making, holidays, and exchanges. The court weighs the child's relationships with each parent and siblings, adjustment to home, school, and community, the mental and physical health of everyone involved, and any history of physical abuse or threats. A parent's military service alone cannot be used against them. Child support follows the Montana Child Support Guidelines, which calculate each parent's obligation from income and parenting time; you can model an estimate with the child support calculator below before your first hearing.
