Montana Grandparent Rights When Raising a Grandchild

What Montana Law Actually Gives Grandparents

Montana grandparents who step in to raise a grandchild get a set of statutory tools that most states don't offer. The two big ones are the Caretaker Relative Educational Authorization Affidavit under MCA 20-5-503 and the Caretaker Relative Medical Authorization Affidavit under MCA 40-6-502. Both let you act on a child's behalf for school and healthcare without going to court and without needing the parent to sign anything.

That second part surprises people. You can execute these affidavits without the parent's signature only when each statute's conditions are met. Both require that the parent voluntarily left the child with you without a definite return date, that the child lives with you full-time, and that no adequate provision already covers the relevant decisions. For school enrollment, you must be unable to contact either parent or a parent you can contact must be unable or unwilling to regain custody. For medical care, you must be unable to locate or contact the parent to notify them of your intended authorization, or the parent must refuse to regain custody after you ask in writing. You sign the affidavits under oath before a Montana notary.

The educational affidavit covers school enrollment, permission slips, parent-teacher conferences, and school-related medical decisions like athletic physicals. A relative acting in the absence of a parent may also be considered a parent with education-record rights under FERPA. The affidavit lasts until the earliest of the end of the first school year after delivery, your revocation, or the child no longer living with you. The medical affidavit covers routine outpatient care — wellness visits, immunizations, dental cleanings, prescriptions, vision exams, and outpatient mental health counseling — and lasts until the earliest of six months after signing, revocation, or the child no longer living with you.

When a Parent Is Available and Willing to Help

If the parent can still sign paperwork — maybe they're in a treatment facility with mail access or serving a shorter sentence — a Minor Power of Attorney under MCA 72-5-103 is often the better choice. The parent signs it, and it delegates care, custody, educational, and medical authority to you for up to six months. Unlike the affidavits, a POA can go to a non-relative too, so it covers situations where a family friend is helping.

The six-month cap means you'll need a fresh signature before each expiration. The cap does not apply to active-duty U.S. military members, Montana National Guard members serving more than 180 continuous days on duty under Title 10 or Title 32 of the U.S. Code or on state military duty defined in MCA 10-1-1003, or federal reserve members serving more than 180 continuous days on duty under Title 10 of the U.S. Code.

Grandparent Visitation Rights Under MCA 40-9-102

Visitation and custody are separate tracks. Under MCA 40-9-102, a grandparent can petition the District Court for visitation rights if a parent is blocking access. But the bar is high: over a fit parent's objection, you need clear and convincing evidence that visitation serves the child's best interest and that the presumption favoring the parent is rebutted.

A visitation order gives you time with the grandchild. It does not give you decision-making authority over school or medical care. For that, you need either the affidavits or a formal guardianship.

When Court Becomes Necessary

The affidavits and POA handle most day-to-day situations. Court becomes the right path when:

• A parent returns and demands the child back after at least six months. MCA 40-6-602 applies when custody was voluntarily given to the relative and the child remained with that relative for at least six months while it was unclear whether or when the parent would return, unless the parent gave and followed a firm return date. In that situation, the relative may maintain temporary custody for five days after the parent returns and demands custody while filing the required affidavit and awaiting the district court's order. If the court finds prima facie evidence of abandonment, its order can continue custody for 14 days; during or after that period, the relative may commence a parenting-plan proceeding or petition for guardianship.
• The child needs major surgery, inpatient psychiatric care, or a passport. These exceed what the medical affidavit and POA authorize.
• You need permanent legal status. Agencies, insurers, and federal programs sometimes require a court-appointed guardian.

Unless limited by the court, a guardian under MCA Title 72, Chapter 5, Part 2 has the powers and responsibilities of a parent. The appointment ends at the minor's majority and may end earlier upon the minor's death, adoption, or marriage, or the guardian's death, court-approved resignation, or removal. You can file in your local District Court, and fee waivers are available if you qualify.

Getting Started

The first step for most Montana grandparents is executing the two statutory affidavits. You'll need a Montana notary (banks, UPS stores, and county clerk offices all offer notary services), and you present the signed originals to the school district and the child's doctor.
