A parenting plan in Montana is a written, court-approved document that allocates parenting time and decision-making authority for a child, governed by Montana Code Annotated (MCA) § 40-4-234. The court determines or approves every plan based on the best interest of the child under Mont. Code Ann. § 40-4-212, and a final plan must be incorporated into the divorce decree.

What Is a Parenting Plan in Montana?
A parenting plan in Montana is the legal document that replaces older "custody" terminology and sets out how separated parents share responsibility for a child. Under MCA § 40-4-234, each parent must submit a proposed final parenting plan in good faith in every dissolution, legal separation, or parenting proceeding involving a child. The plan must be incorporated into the final decree.
Montana law deliberately moved away from the words "custody" and "visitation" in favor of "parenting plan," "residential schedule," and "parenting functions." The statute designates a residential schedule specifying when the child resides with each parent, including holidays, birthdays, vacations, and special occasions. A Montana parenting plan also allocates decision-making authority over the child's education, health care, and religious upbringing. One parent may be designated "custodian" solely for purposes of other state and federal statutes, but that label does not change either parent's rights under the plan itself.
The Best-Interest Standard: MCA 40-4-212
Montana courts decide every parenting plan according to the best interest of the child under Mont. Code Ann. § 40-4-212, weighing at least 10 statutory factors. There is no automatic presumption favoring mothers or fathers; the statute is gender-neutral and focuses entirely on the child's needs, stability, and safety.
When the court must create or approve a custody agreement, it considers all relevant factors. The statute lists these specific best-interest factors:
- The wishes of the child's parent or parents
- The wishes of the child
- The interaction of the child with parents, siblings, and others who significantly affect the child's best interest
- The child's adjustment to home, school, and community
- The mental and physical health of all individuals involved
- Physical abuse or threat of physical abuse by one parent against the other parent or the child
- Chemical dependency or chemical abuse by either parent
- Continuity and stability of care
- The developmental needs of the child
- Whether a parent has knowingly failed to pay birth-related costs the parent is able to pay
Montana also penalizes abusive litigation. Under MCA § 40-4-212, a parenting plan action brought by a parent within 6 months after a child support action against that parent is presumed vexatious. The court also considers adverse effects on the child from continuous and vexatious parenting plan amendment actions.
What a Montana Parenting Plan Must Include
A Montana parenting plan must specify a residential schedule, allocate decision-making authority, and establish a method for resolving future disputes without court action, per MCA § 40-4-234. The plan should be detailed enough that two parents who disagree can still follow it without returning to a judge.
Under the statute, a complete final parenting plan typically addresses these components. Each element exists to reduce future conflict and protect the child's routine:
- Residential schedule: the specific periods of time the child resides with each parent, including a weekday/weekend parenting time schedule and a co-parenting schedule for school terms
- Holiday and vacation schedule: allocation of holidays, school breaks, birthdays of family members, and other special occasions
- Decision-making authority: how parents divide or share major decisions on education, non-emergency health care, and religious training
- Dispute resolution: the method (other than court) parents will use to resolve future disagreements, such as mediation
- Transportation and exchange: where, when, and how the child is exchanged between parents
- Legal residence: designation of the legal residence of both parents and the child
Each parent may make day-to-day decisions while the child is with them, and either parent may make emergency decisions affecting the child's safety or health. When mutual decision-making is designated but the parents cannot agree on a specific issue, they must make a good-faith effort to use the plan's dispute resolution process before going to court.
Filing Fees, Residency, and Timeline
The filing fee for a divorce involving a parenting plan in Montana ranges from $200 to $250 depending on the county, and at least one spouse must have lived in Montana for 90 days before filing. The minimum waiting period is 21 days after service before the court can finalize the decree. As of January 2026, verify the exact fee with your local District Court clerk.
Montana requires that at least one spouse has been domiciled in the state for a minimum of 90 days immediately before filing, codified in MCA § 40-4-104. When children are involved, the child must have resided in Montana for at least 6 months for the court to have jurisdiction over parenting issues under the Uniform Child Custody Jurisdiction and Enforcement Act framework in MCA § 40-4-211. Fee waivers are available for households at or below 125% of federal poverty guidelines by filing a Statement of Inability to Pay Court Costs and Fees.
| Cost / Timeline Item | Amount or Duration | Notes |
|---|---|---|
| Petition filing fee | $200-$250 | Varies by county; verify with clerk (Jan 2026) |
| Response fee | ~$70 | Paid by responding spouse if they file an answer |
| Residency requirement | 90 days | At least one spouse, before filing |
| Child residency for jurisdiction | 6 months | Required for parenting determinations |
| Minimum decree waiting period | 21 days | After service of the petition |
| Fee waiver eligibility | ≤125% poverty line | File Statement of Inability to Pay |
As of January 2026, these figures are subject to change. Verify the current amount directly with your county's District Court Clerk before filing.
Mediation and Dispute Resolution
Montana courts may order parents to participate in mediation or another dispute resolution process to resolve parenting plan conflicts, and most parenting plans require mediation before either parent can ask the court to change the plan. This requirement is designed to keep parents out of court for routine disagreements.
Under MCA § 40-4-234 and MCA § 40-4-219, the court has discretion to order counseling or mediation by a specified person or agency. However, the court may not order mediation in cases involving physical, sexual, or emotional abuse or the threat of such abuse by one parent against the other parent or the child. A parent can opt out of court-ordered mediation by filing a written motion citing MCA § 40-4-301, which identifies when mediation is not appropriate. When abuse exists but parents still wish to mediate, each parent must provide written, informed consent. Mediation is frequently faster and far less expensive than a contested hearing, and a mediated parenting time schedule that both parents helped design is more likely to last.
Modifying a Montana Parenting Plan
A Montana parenting plan can be amended under MCA § 40-4-219 only if the parent shows a change in the child's circumstances since the prior plan and that the amendment is necessary to serve the child's best interest. Most plans cannot be changed until at least 6 months after the court ordered the current plan, and the standard is intentionally high to protect stability.
The court applies a two-part test: first, facts must have arisen since the prior plan or have been unknown to the court at the time, showing a change in the child's circumstances; second, the amendment must be necessary to serve the best interest of the child under MCA § 40-4-212. A motion to amend is presumed vexatious if a parent seeks to amend without first making a good-faith effort to comply with the plan or its dispute resolution provisions. Attorney fees and costs may be assessed against a party who files a frivolous or repeated amendment action. A proposed amended parenting plan must be filed and served with the motion. Preference is given to carrying out the existing parenting plan rather than disrupting the child's routine.
Relocation and Notice of Intent to Move
A Montana parent who plans to move must give the other parent written notice, and if the move significantly affects the child's contact with the other parent, the relocating parent must file a motion to amend the residential schedule at least 30 days before the move under MCA § 40-4-217. The other parent then has 21 days to respond. Failure to respond within 21 days constitutes acceptance of the proposed revised schedule.
The statute requires a specific notice statement warning the receiving parent that the relocation and revised residential schedule may be ordered without further proceedings unless the parent files a response and an alternate schedule within 21 days. If the receiving parent objects, the response must include an alternate proposed revised residential schedule. When evaluating relocation, the court considers the reasons each parent gives for seeking or opposing the move, whether the relocating parent has shown willingness to promote the child's relationship with the non-relocating parent, and whether reasonable alternatives to the move exist. Montana provides a self-help form (Notice of Intent to Move) filed at the Clerk of District Court in the county where the parenting plan was ordered. These two timeframes — 30 days before the move to file, 21 days after service to respond — are strict and frequently litigated.
DIY vs. Attorney: Choosing Your Approach
Parents who agree on all parenting terms can file a Joint Petition using Montana's free court forms and finalize a parenting plan in roughly 21 to 60 days, while contested cases involving disputed parenting time often take 6 to 18 months and benefit from attorney representation. The right approach depends on the level of conflict and the complexity of the parenting issues.
| Factor | Uncontested (Joint) | Contested |
|---|---|---|
| Typical timeline | 21-60 days | 6-18 months |
| Court forms | Joint Petition (MP-115) | MP-112 / MP-113 |
| Cost | $200-$250 filing fee | Filing fee plus attorney fees |
| Mediation | Often optional | Frequently court-ordered |
| Best for | Full agreement on parenting | Disputes over time or safety |
Montana offers free standardized parenting plan forms through the Montana Judicial Branch self-help center, which makes a do-it-yourself custody agreement realistic for cooperative parents. When abuse, substance dependency, relocation, or significant disagreement over the co-parenting schedule is involved, consulting a Montana family law attorney protects the child's interests and reduces the risk of a plan that fails to hold up.
