Montana Parenting Plan: How to Build a Court-Ready Plan Step by Step

Every Montana dissolution or parenting case involving minor children requires a parenting plan before the judge will sign a final decree. Walk into the District Court with a vague proposal and the judge sends you back. Walk in with a detailed, specific plan and you leave with a signed order the same day.

Here is exactly what Montana law requires in your parenting plan and how to build one that gets approved on the first attempt.

What Montana Law Requires in a Parenting Plan

Under MCA § 40-4-234, every parenting plan filed with the District Court must address six mandatory elements:

Legal residence designation. Both parents' addresses and the children's primary residence for school enrollment and jurisdictional purposes.

Detailed residential schedule. A day-by-day calendar showing exactly when the child lives with each parent during the regular school year, including specific transition times (not "reasonable parenting time" — judges reject vague language).

Holiday, vacation, and special occasions schedule. This overrides the standard weekly rotation for Thanksgiving, Christmas, spring break, summer vacation, and birthdays.

Financial support provisions. Child support calculated under Montana's Melson-style guidelines, plus health insurance, childcare costs, and extraordinary expense allocation.

Decision-making authority. Whether major decisions about education, healthcare, and spiritual development are shared between parents or assigned to one parent.

Dispute resolution process. A binding clause requiring mediation or another alternative dispute resolution method before either parent can file a motion with the court.

Montana Replaced "Custody" With Parenting Plans

In 1997, Montana eliminated the terms "custody" and "visitation" from its family law code. The court now uses "parenting time," "residential schedule," and "decision-making authority." If you search online using traditional custody language, you will find national articles that do not match Montana's actual court forms.

The MP-300 Proposed Parenting Plan form — the document you file with the District Court — asks you to fill in residential schedules, transition protocols, and decision-making allocations. It does not mention "custody" or "visitation" anywhere.

How to Write the Residential Schedule

The residential schedule is the section most parents struggle with because the MP-300 form gives you blank boxes with no suggested language.

Be precise with transition times. Write "Parent A's parenting time begins Friday at 6:00 PM and ends Sunday at 6:00 PM" — not "every other weekend."

Match the schedule to your child's developmental stage. Montana courts evaluate whether your proposed schedule fits your child's age:

• Infants (0–18 months): Shorter, frequent visits with the non-residential parent — typically three blocks of 3–4 hours per week, no overnights unless the non-residential parent was a primary caregiver.
• Toddlers (18 months–3 years): Two midweek afternoon blocks plus one weekend overnight, gradually increasing.
• School-age (6–12): A 2-2-3 rotation keeps the child from being away from either parent for more than three consecutive days.
• Teenagers (13+): Alternating weeks with Sunday evening transitions, flexible enough to accommodate extracurricular activities.

Include a right-of-first-refusal clause. Specify a time threshold (4, 6, or 8 hours): if a parent cannot care for the child during their parenting time beyond that threshold, they must offer the other parent the opportunity before using a third-party caregiver.

Holiday and Vacation Scheduling

The holiday schedule overrides the regular weekly rotation, so it needs to be explicit. Montana plans typically alternate major holidays on an odd-year/even-year basis:

• Thanksgiving, Christmas Eve/Day, New Year's Eve/Day
• Spring break and summer vacation (split or alternating blocks)
• Each parent's birthday with the child, Mother's Day, Father's Day

Specify exact pickup and drop-off times for each holiday. A common mistake is writing "parents will share Christmas" — this creates an argument every December. Instead: "In even-numbered years, Child is with Parent A from December 24 at 10:00 AM through December 25 at 6:00 PM."

Decision-Making Authority Options

Montana distinguishes between two types of decision-making:

Shared (joint) decision-making means both parents must agree on major decisions about education, healthcare, and religious upbringing. This works when parents communicate effectively.

Sole decision-making assigns these decisions to one parent. Courts order this when communication has broken down or when there is a history of domestic violence, substance abuse, or deliberate obstruction.

Even with shared decision-making, Montana courts typically allow the parent with the child to make routine daily decisions (meals, bedtime, homework supervision) without consulting the other parent.

Filing Your Plan With the District Court

File your Proposed Parenting Plan (MP-300) with the Clerk of the District Court in the county where your children live. The filing fee is $200 ($170 petition fee + $20 civil surcharge + $10 technology fee). If you cannot afford the fee, file Form MP-001 to request a waiver.

If both parents agree on the plan, file a Joint Petition (MP-117) — no summons is required and the court can approve your plan faster.

If you are filing on your own, you must formally serve the other parent with the Summons and Petition, and they have 21 days to respond with their own proposed plan.

Build a Complete Plan Before You File

The difference between a plan that gets approved and one that gets sent back is specificity. Judges want to see exact times, clear holiday rotations, and a workable dispute resolution process — not a loose outline of good intentions.

The Montana Child Custody & Parenting Plan Guide walks you through every section of the MP-300 form with pre-written scheduling language, transition scripts, and worksheets for tracking parenting days — so your plan is ready for the judge's signature the first time you file.
