What Rights Do Grandparents Have in Montana?

Grandparents’ rights in Montana come down to two possibilities: you can ask a district court for scheduled contact with your grandchild under Montana Code 40-9-102, or, in more serious situations, you can ask for custody under Montana Code 40-4-228. Either path requires clear and convincing evidence, and if the child’s parent is fit and objects, you also have to overcome a legal presumption that the parent’s decision was the right one.¹

What You Can Ask For: Contact or Custody

These are two different requests with two different statutes, and picking the right one matters.

Contact under MCA 40-9-102 means scheduled time with your grandchild. Think of it as visitation. You do not gain any say over the child’s schooling, medical care, or day-to-day upbringing. You can petition for contact at any time; Montana does not require a divorce, a death, or any other triggering event before you file.¹

A “parental interest” under MCA 40-4-228 is essentially custody. To get it, you have to show two things by clear and convincing evidence: that the natural parent has engaged in conduct contrary to the parent-child relationship, and that you have an established parent-child relationship with the grandchild that should continue in the child’s best interests. The statute specifically says that voluntarily leaving a child in someone else’s care for a significant period counts as conduct contrary to the parent-child relationship, and the court does not have to formally find the parent “unfit” to award custody under this provision.²

If you are raising a grandchild full-time because a parent is incarcerated, struggling with addiction, or absent, a custody petition under 40-4-228 may fit your situation better than a contact petition under 40-9-102.

The Standard You Have to Meet

Montana’s contact statute is designed around a U.S. Supreme Court principle: fit parents are presumed to act in their children’s best interests, and courts must give special weight to a fit parent’s decisions about who spends time with the child.³ That principle shapes the two-track test courts apply when a parent objects.

First, the court decides whether the objecting parent is fit. Fitness here means basic adequate care of the child. It is not about whether the parent is perfect or whether the parent makes decisions you agree with.¹

If the court finds the parent unfit, you still have to prove by clear and convincing evidence that contact is in the child’s best interest. Clear and convincing is a tougher standard than the “more likely than not” rule used in most civil cases; it means the evidence has to be definite and convincing, not just slightly stronger than the other side’s.

If the parent is found fit, the climb gets steeper. You have to show, by clear and convincing evidence, both that contact is in the child’s best interest and that the presumption favoring the parent’s wishes has been rebutted.¹ In practice, that means concrete evidence that the child benefits from the relationship. Wanting to be involved is not enough.

One protection worth knowing: if the court finds a parent unfit for purposes of your contact petition, that finding does not spill over into other legal proceedings unless the court orders otherwise.¹

What Courts Look At

The statute keeps the focus on the child’s best interest without listing specific factors. Montana courts have filled in the picture through case law, and the considerations that tend to matter most include:

The depth of the existing relationship. A grandparent who has provided regular care, attended school events, or spent significant time with the child comes in with a stronger case than one who has been a distant presence.
The emotional bond between you and the child, and whether disrupting it would harm the child.
The parent’s reasons for objecting. Reasoned concerns about the child’s welfare carry significant weight; a fit parent can raise specific objections to pieces of a proposed visitation plan, and if you cannot rebut them, the court can strike those pieces.
The child’s own preferences, if the child is old enough and mature enough to express them.
Family circumstances, including divorce, separation, or the loss of a parent.

The practical takeaway is to come in with a realistic, flexible proposal rather than an ambitious wish list, and to be ready with concrete evidence of your involvement: photographs, communications, testimony from people who have seen the relationship, and, where helpful, input from counselors or educators.

How to File a Petition for Contact

You start by filing a petition in the district court. The petition should describe your relationship with the grandchild, explain why contact serves the child’s best interests, and address whether a parent has objected.

Once you file, the court notifies the parents and gives them a chance to respond. If both parents consent, the case is straightforward. If a parent objects, the court holds a hearing and must first determine whether that parent is fit before reaching the merits of your petition. Both sides present evidence at the hearing. The court can also appoint a guardian ad litem to investigate independently, or appoint an attorney for the child if the child’s interests are not adequately represented.¹

Montana district courts charge filing fees for family law petitions. A separate fee for a grandparent contact petition is not listed in the published schedule, but similar family filings in Montana generally run in the range of $100 to $200. If you cannot afford the fee, you can ask the court for a waiver. Attorney costs are usually the larger expense, especially in contested cases.

If the grandchild is involved in an abuse, neglect, or dependency case under Title 41, you can still petition under 40-9-102, but the Department of Public Health and Human Services must be notified.¹

The Two-Year Rule on Refiling

You cannot bring the same contact petition more than once every two years unless there has been a significant change in circumstances affecting the child, the parent, or you.¹ The rule exists so that repeated filings do not become a tool for pressure or ongoing family disruption. If your petition is denied, plan on waiting two years, or be ready to show the court that something has materially changed.

When Adoption Ends Your Rights

Adoption is the one event that can wipe out grandparent contact rights entirely. If your grandchild is adopted by someone other than a stepparent or another grandparent, MCA 40-9-102 no longer applies. Any existing contact order terminates automatically, and you lose the ability to petition for future contact under this statute.¹

Two exceptions survive. If a stepparent adopts the child, your rights continue. The same is true if another grandparent adopts. In other adoption scenarios, there is no mechanism in this statute to restore contact once the adoption is final, so if you learn adoption proceedings are underway, act quickly.

Changing or Ending an Existing Order

Either you or a parent can ask the court to modify or terminate an existing contact order. The petitioner must show a significant change in circumstances since the original order. That might be a parent’s relocation, a shift in the child’s needs, a change in the relationship between you and the parent, or evidence that the current arrangement is harming the child.¹

The court looks at the same best-interest factors again, but through the lens of what is happening now. If continued contact is hurting the child, or the reasons for granting it no longer hold, the court can reduce the schedule or end it. A parent trying to terminate contact has to meet the same evidentiary burden in reverse: show the circumstances have changed and that ending contact serves the child. The two-year filing restriction also applies to modification requests unless the changed-circumstances exception is met.
