Montana grandparents can petition a district court for grandparent-grandchild contact under Mont. Code Ann. § 40-9-102. When a fit parent objects, the grandparent must prove by clear and convincing evidence that contact serves the child's best interest and must rebut the constitutional presumption that the parent's decision is correct. Filing fees run roughly $120 to $250.

What Is the Legal Standard for Grandparent Visitation in Montana?
Montana grants grandparent visitation under Mont. Code Ann. § 40-9-102, which authorizes a district court to grant a grandparent reasonable rights to contact with a grandchild when contact serves the child's best interest. When a fit parent objects, the grandparent must prove by clear and convincing evidence that visitation benefits the child and must rebut the presumption favoring the parent's wishes.
The grandparent visitation statute, now titled "Grandparent-grandchild contact," was originally enacted in 1979 and has been amended at least eight times, including in 1983, 1991, 1995, 1997, 2007, and 2009. Montana law calls this "grandparent-grandchild contact" rather than "visitation" or "custody," because the state retired the words "custody" and "visitation" in favor of "parenting" terminology. A proceeding must be entitled "In re the grandparent-grandchild contact of..." and the initial pleading must be denominated a petition. The court applies the Montana Rules of Civil Procedure to all proceedings under Mont. Code Ann. § 40-9-101 and § 40-9-102.
How Does Troxel v. Granville Affect Montana Grandparent Rights?
The U.S. Supreme Court decision Troxel v. Granville, 530 U.S. 57 (2000), controls every Montana grandparent visitation case by requiring courts to presume that a fit parent's decision about contact is in the child's best interest. Montana courts implement Troxel by placing the full burden on the grandparent, not the parent, to overcome that presumption with clear and convincing evidence.
In Troxel, the Supreme Court held that the parental liberty interest in the care, custody, and control of children is "perhaps the oldest of the fundamental liberty interests" recognized by the Court. The constitutional defect in Troxel was that the trial judge improperly placed the burden on the fit parent to disprove that visitation would benefit the children. Montana's framework corrects this by requiring the grandparent to carry the burden. In Polasek v. Omura (2006), the Montana Supreme Court confirmed that a petitioning grandparent must prove by clear and convincing evidence both that contact serves the child's best interest and, when a fit parent objects, that the presumption favoring the parent's wishes has been rebutted. This places Montana among states with a Troxel-compliant, parent-protective grandparent visitation regime.
What Is the Difference Between a Fit and Unfit Parent?
Montana applies two different standards depending on parental fitness, and the court must determine fitness before granting any petition over a parent's objection. Under Mont. Code Ann. § 40-9-102, fitness is measured by whether the parent adequately cares for the child, and the determination is made only after a hearing on proper notice.
If the court finds a parent unfit, grandparent-grandchild contact may be granted over the objection only when the court also determines by clear and convincing evidence that the contact serves the child's best interest. If the parent is fit, the grandparent faces a heavier task: the grandparent must show that visits serve the child's best interest and must additionally rebut the presumption that the fit parent's wishes are correct. A finding of unfitness under this section has no effect on a parent's other rights, except regarding grandparent contact, unless the court orders otherwise. The statute requires that the Department of Public Health and Human Services receive notice of any petition concerning a child involved in a Title 41 or Title 40 administrative or court proceeding.
Comparison: MCA § 40-9-102 vs. § 40-4-228
Montana grandparents may pursue contact through two distinct statutes, and the path matters because the burdens differ dramatically. The grandparent visitation statute, Mont. Code Ann. § 40-9-102, governs ordinary grandparent contact, while the third-party parental interest statute, Mont. Code Ann. § 40-4-228, allows a grandparent to seek a broader parental interest.
| Feature | § 40-9-102 (Grandparent Contact) | § 40-4-228 (Parental Interest) |
|---|---|---|
| What it grants | Reasonable contact/visitation | Full parental interest or visitation |
| Burden for visitation | Best interest; rebut parent presumption | Best interest of the child |
| Burden for parental interest | Not available | Clear and convincing evidence (two-part test) |
| Unfitness required | Fitness determination required | Not necessary to find parent unfit |
| Filing frequency | Once every two years absent changed circumstances | Governed by Chapter 4 procedures |
| Constitutional review | Troxel presumption applies | Strict scrutiny |
Under Mont. Code Ann. § 40-4-228, a court may award a full parental interest only on clear and convincing evidence that the natural parent engaged in conduct contrary to the child-parent relationship and that the nonparent established a child-parent relationship whose continuation serves the child's best interest. In In re the Parenting Plan of L.M.A.R. and N.R.R. (2024), the Montana Supreme Court held that grandparents may properly seek third-party parental status under § 40-4-228, distinct from § 40-9-102 contact.
How Often Can Grandparents File a Petition in Montana?
Montana grandparents may file a petition for grandparent-grandchild contact once every two years under Mont. Code Ann. § 40-9-102, unless circumstances have significantly changed. This biennial limit prevents repeated litigation that would burden a fit parent and the child with continuous court proceedings.
The two-year restriction reflects Montana's effort to balance grandparent access against the constitutional protection of parental decision-making recognized in Troxel. If a grandparent's first petition is denied, the grandparent generally must wait two years before refiling, absent a significant change such as a parent's death, the onset of abuse or neglect, or a major shift in the family circumstances that materially affects the child's welfare. Because this is a strict procedural limit, grandparents should prepare the strongest possible evidentiary record on the first filing. A grandparent seeking third-party parental status under Mont. Code Ann. § 40-4-228 follows Chapter 4 procedures instead, which are not subject to the same two-year contact rule. Consulting a Montana family law attorney before filing helps avoid procedural missteps that could waste a filing window.
How Does Adoption Affect Grandparent Visitation?
Adoption generally terminates grandparent visitation rights in Montana, with two narrow exceptions. Under Mont. Code Ann. § 40-9-102, the grandparent contact statute does not apply, and any contact previously granted terminates, when the child is adopted by a person other than a stepparent or a grandparent.
This means that if a child is adopted by an unrelated family, the legal relationship to the biological grandparents is severed and the statute no longer provides a basis for court-ordered contact. The two preserved exceptions are significant: a stepparent adoption (common when a custodial parent remarries) does not terminate grandparent contact rights, and a grandparent adoption likewise preserves the statutory framework. These exceptions recognize that stepparent and grandparent adoptions typically keep the child within an existing family network where continued grandparent relationships often serve the child's best interest. Grandparents facing a pending adoption that would cut off contact should act before the adoption is finalized, because once a non-exempt adoption decree is entered, the statutory door to grandparent contact generally closes. Title 41 proceedings involving the child trigger additional notice requirements to the Department of Public Health and Human Services.
What Does Montana Consider in a Child's Best Interest?
Montana courts evaluate grandparent contact and all parenting matters under the best-interest factors in Mont. Code Ann. § 40-4-212, which require the court to weigh the child's relationships, stability, and welfare. Among the listed factors, the court specifically considers the interaction of the child with parents, siblings, and other persons who may significantly affect the child's best interest.
The statutory best-interest factors include the wishes of the parents, the wishes of the child, the child's interaction and interrelationship with parents and siblings and other significant people, the child's adjustment to home, school, and community, the mental and physical health of everyone involved, any history of physical abuse or threats, chemical dependency or abuse, and continuity and stability of care. For grandparent contact specifically, courts emphasize the existing bond between grandparent and grandchild, the duration and quality of the relationship, and whether severing contact would harm the child. Because Troxel requires deference to fit parents, evidence that the grandparent provided substantial care, served as a primary caregiver, or maintained a deep and stable relationship strengthens a petition. Mere disagreement with a parent's parenting choices is insufficient to overcome the parental presumption.
What Are the Filing Fees and Procedures in Montana?
Filing a petition in a Montana district court generally costs between $120 and $250, depending on the county and the specific fee components. The base district court filing fee is approximately $120 under Mont. Code Ann. § 25-1-201, and some counties add a $50 judgment fee or additional charges, producing totals reported between $170 and $250. As of January 2026, these amounts vary by county. Verify with your local clerk.
Grandparents file in the Clerk of the District Court in the county where the child or relevant parties reside. The petition must be properly captioned, and notice must be provided as the court directs. If a Title 41 or Title 40 administrative or court proceeding involves the child, the Department of Public Health and Human Services must receive notice of the petition. Fee waivers are available: a grandparent who cannot afford the filing fee may submit an Affidavit of Inability to Pay Filing Fee, and Montana courts may waive fees for households at or below 125% of the federal poverty guidelines. The court schedules a hearing, makes the required fitness determination when a parent objects, and applies the appropriate evidentiary standard. Montana official court forms and information are available through the Montana Judicial Branch self-help resources at courts.mt.gov.
Should You Hire a Montana Family Law Attorney?
Grandparent visitation cases in Montana are legally complex because they require overcoming a constitutional presumption favoring fit parents under both Troxel v. Granville and Mont. Code Ann. § 40-9-102. An experienced Montana family law attorney can assess whether to proceed under the grandparent contact statute or the third-party parental interest statute, Mont. Code Ann. § 40-4-228, which carry different burdens of proof.
Because the clear-and-convincing-evidence standard is demanding and grandparents may generally file only once every two years, the quality of the first petition is critical. An attorney can help build the evidentiary record needed to document the grandparent-grandchild relationship, the child's best interest, and the rebuttal of the parental presumption when a fit parent objects. Counsel can also evaluate strict-scrutiny implications for parental interest claims and navigate notice requirements, including notice to the Department of Public Health and Human Services in Title 41 matters.
