Quick answer: How long a child custody case takes in Montana depends almost entirely on one thing — whether both parents can agree. Agreed parenting plans are typically finalized in 2 to 4 months. Contested cases where parents disagree take an average of 6 to 18 months. High-conflict cases that go to trial can stretch to 18 to 24 months or longer. This guide walks through each scenario, the Montana-specific rules that affect your timeline, and what you can do right now to protect your children while the case is open.

How Long Does a Child Custody Case Take in Montana?
First: Montana Calls It a “Parenting Plan,” Not a Custody Order
Before getting into timelines, there is one thing worth knowing about how Montana handles this differently from most other states.
Montana law no longer uses the words “custody” and “visitation.” Instead, the court uses “parenting” and “parenting plan.” A parenting plan is the legal document that covers where your children live, how much time they spend with each parent, and how big decisions — school, healthcare, religion — get made. It is the Montana version of what other states call a custody order.

The terms are used interchangeably throughout this article, but when you go to the Missoula County District Court, the paperwork will say “Petition for Parenting Plan,” not “custody petition.”
The Three Types of Montana Custody Cases — and How Long Each Takes
Type 1: Agreed (Stipulated) Parenting Plan — 2 to 4 Months
This is the fastest path. Both parents sit down — with or without attorneys — and work out a parenting plan they both agree on. The plan gets submitted to the court. A judge reviews it to confirm it serves the children’s best interests. If approved, it becomes a legally enforceable order.
When both parents are cooperative, and the plan covers all required elements, this process often wraps up within 60 to 120 days of the filing date. The main time factors are:
- How quickly is the paperwork prepared and filed
- How backed up is the Missoula County District Court calendar
- Whether child support calculations are included and accurate
- Whether paternity has been established (for unmarried parents)
This path is almost always better for children and far less expensive for both parents. If you can agree, agree — even on the hard things. A parenting plan you both helped write will work better long-term than one a judge imposes after a trial.
Type 2: Contested Case Settled Through Mediation — 4 to 12 Months
When parents disagree, the case becomes contested. Montana courts almost always require parents to try mediation before a final hearing. A mediator is a trained, neutral third party who helps both parents work toward an agreement they can live with.
Mediation is not the same as going to court. It is a private meeting — both parents can bring their attorneys — where the mediator helps find middle ground. If mediation works, the agreement becomes a Stipulated Parenting Plan and gets filed with the court.
The contested-but-settled path typically looks like this:
- Month 1–2: File petition, serve the other parent, wait for their response (21 days)
- Month 2–3: Court issues a Scheduling Order setting case deadlines; an Interim Parenting Plan is put in place if needed
- Month 3–6: Mediation ordered and completed
- Month 6–10: Agreement finalized and submitted to the court for approval
- Month 10–12: Final Parenting Plan signed by judge
Note: The court may order mediation more than once if the first session doesn’t resolve everything.
Important exception: Montana law (MCA 40-4-219) states that mediation is not appropriate in cases involving domestic violence or abuse. If there has been physical abuse or a threat of physical abuse, do not go to mediation. Tell your attorney immediately. Court action may be the only appropriate path.
Type 3: Fully Contested Case That Goes to Trial — 12 to 24+ Months
When parents cannot agree even after mediation, a judge holds a final hearing or trial. The judge hears both sides and decides the parenting plan based on the best interests of the child.
This is the longest, most expensive path. It is also the least predictable — because once you put the decision in a judge’s hands, neither parent controls the outcome. The judge will issue a plan based on the law and the evidence, which may not match what either parent wanted.
A contested trial adds several layers that each take time:
- Discovery: Both sides exchange information, documents, and sometimes depose witnesses
- Parenting evaluator: The court may appoint a professional to assess the family and make a recommendation. Full evaluations take 2 to 6 months and cost between $5,000 and $30,000
- Guardian ad litem: The court may appoint an attorney to represent the children’s interests (MCA 40-4-205)
- Court scheduling: Missoula District Court trial dates book out weeks or months in advance
- The trial itself: may span multiple days or hearings spread over weeks
If a parenting evaluator is involved, expect to add 3 to 6 months to the timeline — minimum. If the case goes to full trial, 18 to 24 months from filing to final order is realistic for a high-conflict case in Montana.
Timeline Summary at a Glance
| Case Type | Typical Timeline | Key Driver |
|---|---|---|
| Agreed / Stipulated Parenting Plan | 2 to 4 months | Both parents cooperate; paperwork complete |
| Contested — Settled at Mediation | 4 to 12 months | Disagreement resolved before trial |
| Contested — Goes to Trial (no evaluator) | 12 to 18 months | The judge decides after hearing |
| High-Conflict — Parenting Evaluator Involved | 18 to 24+ months | Evaluation adds 3–6 months; complex trial |
| Emergency / Immediate Danger | Days to weeks | The court can act immediately under MCA 40-4-220 |
| Modification of Existing Plan | Weeks to 18 months | Agreed vs. contested; must show changed circumstances |
These are general ranges based on Montana law and common court experience. Your actual timeline depends on your specific facts, which county you’re in, and current court scheduling. Always verify your timeline with a licensed Montana family law attorney.
What Happens While the Case Is Open: Interim Parenting Plans
One of the most important things to understand is that you don’t have to wait 12 months with no legal structure in place. From the moment you file, you can ask the court for an Interim Parenting Plan — a temporary order that governs where the children live and how time is divided while the permanent plan is being worked out.
Under MCA 40-4-213, either parent can request an Interim Parenting Plan at any point in the case. The court can put one in place with or without a full hearing, depending on the circumstances.
If the situation is a true emergency — a child is in danger, or one parent is about to take the children out of state without permission — the court can act even faster. Under MCA 40-4-220, a parent may request an emergency temporary order on an ex parte basis, meaning the court may act without the other parent present. These orders are short-term and require a follow-up hearing quickly, but they can provide immediate protection when children are at risk.
Important: Getting an Interim Parenting Plan in place early protects your children and your parental rights. It also creates the structure that makes day-to-day life manageable while the case is resolved. Ask your attorney about this at your very first meeting.
The Seven Things That Slow a Montana Custody Case Down
Every case is different, but these are the most common reasons cases take longer than expected:
1. The Other Parent Contests Everything
When one parent disagrees with the proposed plan, the court has to hear both sides. More disagreement means more hearings, more paperwork, and more time. Parents who argue about every detail — including minor scheduling issues — can stretch a case from 4 months to well over a year.
2. A Parenting Evaluator Is Ordered
In complex or high-conflict cases, the court may appoint a parenting evaluator — a mental health professional who interviews both parents, the children, teachers, doctors, and others, then writes a report with recommendations. This process alone typically takes 2 to 6 months and can cost $5,000 to $30,000 or more, usually split between the parents. The evaluator’s report carries significant weight with the judge.
3. A Guardian Ad Litem Is Appointed
Under MCA 40-4-205, the court can appoint a guardian ad litem — typically an attorney — to represent the children’s interests independently of both parents. This adds another party to the case, more hearings, and more time.
4. Domestic Violence Allegations
When abuse is alleged, the case typically involves additional hearings, protective order proceedings, and potentially a separate criminal case that runs concurrently. Safety concerns take priority, but they also add complexity and time. Mediation is not appropriate in these situations (MCA 40-4-219).
5. Paternity Has Not Been Established
If the parents were not married, paternity must be legally established before the court can enter a parenting plan. This can be done administratively through the Montana Child Support Services Division or through the court, but it adds time to the front end of the case.
6. One Parent Is Unresponsive or Non-Compliant
If the other parent does not respond to the petition, misses deadlines, or refuses to participate in mediation, the case slows down. The court can eventually enter a default order, but that process has its own timeline and requirements.
7. Court Scheduling in Missoula
Missoula County District Court handles a significant volume of family law cases. Hearing dates and trial slots can be weeks or months out, depending on the court’s calendar. An experienced local attorney knows the court’s schedule and can often anticipate these delays.
What the Court Looks at When Deciding Your Parenting Plan
Whether your case settles or goes to trial, everything comes back to one legal standard: the best interests of the child (MCA 40-4-212).
Montana law does not favor mothers over fathers. It does not assume that more time with one parent is automatically better. The court considers all of the relevant facts about your family, including:
- The wishes of each parent
- The child’s age, developmental needs, and adjustment to their current home and school
- The quality of the relationship between each parent and the child
- The mental and physical health of each parent
- Each parent’s ability to provide a stable, nurturing environment
- Whether there is any history of physical abuse or threat of abuse against the child or the other parent
- Each parent’s willingness to support the child’s relationship with the other parent
- The child’s wishes — considered in proportion to the child’s age and maturity (there is no set age in Montana law; judges evaluate this case by case)
- Whether either parent has failed to pay child support, they were able to pay
Montana law also presumes that frequent and continuing contact with both parents is in the child’s best interests — unless evidence shows that contact with one parent would harm the child (MCA 40-4-212).
This means that if you are trying to limit the other parent’s time, you need concrete, specific evidence that it is necessary for your child’s well-being. Frustration with your co-parent — or wanting to “win” — is not a legal basis for limiting contact.
How to Modify an Existing Parenting Plan in Montana
Once a Final Parenting Plan is in place, it can be changed — but the bar is higher than the original case.
Under MCA 40-4-219, to modify a parenting plan in Montana, you generally must show:
- There has been a significant change in circumstances since the plan was ordered, and
- The change is necessary to protect the best interests of the child
You must also wait at least 6 months after the original plan was ordered before filing a modification in most cases — unless there is an emergency.
Montana courts take a dim view of parents who file repeated modification requests without good cause. The law specifically allows courts to order the filing parent to pay the other parent’s attorney fees if the modification request is found to be frivolous or intended to harass.
Agreed modifications — where both parents agree on the changes — can be finalized in a matter of weeks. Contested modifications follow a similar timeline to the original case.
What You Can Do Right Now to Protect Your Children
Waiting for a case to resolve does not have to mean living in limbo. Here are the most important steps to take from day one:
1. Document everything.
Keep a simple written log of parenting time, significant events, and any concerns about the other parent’s behavior. Dates, times, brief notes. This becomes evidence if the case is contested.
2. Never withhold the other parent’s time without a court order.
Even if you believe the other parent is acting poorly, unilaterally cutting off their time with the children — without a court order — will hurt your case. The court views parental interference very seriously. If you have safety concerns, consult an attorney and obtain a court order.
3. Put your children first in every decision.
The judge is going to ask one question over and over: what is best for these children? Parents who consistently demonstrate child-centered thinking — in court and out — are viewed more favorably. Parents who use the case to punish each other are not.
4. Get an Interim Parenting Plan in place immediately.
Don’t operate without structure during the case. An interim plan establishes a baseline, protects your parenting time, and provides the children with stability while the permanent plan is developed.
5. Talk to an attorney before you act.
Decisions made in the first weeks of a case can affect the outcome for years. A free consultation costs nothing and can prevent mistakes that extend your case and harm your position.

Frequently Asked Questions
How long does a child custody case take in Montana?
It depends on whether parents agree. An agreed parenting plan can be finalized in 2 to 4 months. A contested case where parents disagree typically takes 6 to 18 months. High-conflict cases involving a parenting evaluator or trial can take 18 to 24 months or more. Your specific situation will depend on your county, your facts, and whether the other parent cooperates.
Can I get temporary custody orders right away in Montana?
Yes. Under MCA 40-4-213, either parent can request an Interim Parenting Plan at the start of the case to establish a temporary structure while the permanent plan is developed. In true emergencies — when a child is in immediate danger — a court can issue an emergency order on an ex parte basis (without the other parent present) under MCA 40-4-220.
What is the difference between a parenting plan and a custody order in Montana?
Montana no longer uses the words “custody” and “visitation.” The courts use “parenting” and “parenting plan.” A parenting plan is the legal document that sets out where children live, how much time they spend with each parent, and how major decisions are made. It is the Montana equivalent of what most states call a custody order.
What slows down a custody case in Montana?
The biggest delays come from the other parent contesting the plan, a parenting evaluator being ordered (which alone adds 2 to 6 months), domestic violence allegations requiring additional hearings, Missoula County court scheduling backlogs, and one parent failing to meet deadlines or cooperate with the process.
How long does it take to modify a parenting plan in Montana?
Montana law generally requires waiting at least 6 months after the original plan is ordered before filing for a modification (MCA 40-4-219), unless there is an emergency. Agreed modifications can be finalized in weeks. Contested modifications follow a similar timeline to the original case — 6 to 18 months in most situations.
Does Montana favor mothers or fathers in custody cases?
No. Montana law does not favor either parent based on gender. Courts decide parenting plans based entirely on the best interests of the child under MCA 40-4-212. Montana law also presumes that frequent and continuing contact with both parents benefits the child, unless specific evidence shows otherwise.
