Aunt, Uncle, or Family Friend Raising a Child in Montana

The Rules Are Different for Relatives and Non-Relatives

Montana's out-of-court consent system draws a hard line between blood/marriage/adoption relatives and everyone else. If you're an aunt, uncle, or adult sibling, you have access to the same statutory affidavits that grandparents use. If you're a family friend, godparent, or anyone the law calls "fictive kin," those affidavits are off limits — and your path is narrower.

Understanding which side of that line you're on determines everything about how you get a child into school and to the doctor.

Aunts, Uncles, and Adult Siblings

You qualify for Montana's Caretaker Relative Educational Authorization Affidavit (MCA 20-5-503) and Medical Authorization Affidavit (MCA 40-6-502) on the same terms as a grandparent. Both require the caretaker to be at least 18 and related by blood, marriage, or adoption; a parent must have voluntarily left the child with the caretaker without a definite return date; the child must live there full-time; and no adequate arrangement can already cover the relevant decision. For school enrollment, MCA 20-5-502 also requires that you be unable to contact either parent or that a parent you can contact be unable or unwilling to regain custody. For medical care, MCA 40-6-502 requires that you be unable to locate or contact the parent to notify them of your intended authorization, or that the parent refuse to regain custody after you ask in writing.

The "by marriage" part matters. A married aunt's spouse isn't a blood relative of the child, but the marriage creates the qualifying relationship. First cousins and great-grandparents also qualify.

You sign these affidavits yourself before a Montana notary. No parental signature needed. The educational affidavit gets the child into school; the medical affidavit covers routine healthcare. Together, they handle the daily decisions.

If the parent is available and willing to help, a Minor Power of Attorney (MCA 72-5-103) is another option — the parent signs it, and it delegates broader authority to you for up to six months.

Family Friends and Fictive Kin

This is where Montana law creates a real barrier. The statutory affidavits are restricted to relatives by blood, marriage, or adoption. A family friend, godparent, coach, or neighbor — no matter how close the relationship or how clearly they're the right person to care for the child — cannot execute them.

Your options:

If the parent can sign: A Minor Power of Attorney under MCA 72-5-103. Unlike the affidavits, a POA can be granted to any adult, relative or not. The parent signs it. Notarization is not required for execution, but under MCA 72-31-305, acknowledging the signature before a notary makes it presumptively genuine. It can delegate care, custody, educational, and medical authority for up to six months.

If the parent can't or won't sign: Court guardianship under MCA Title 72, Chapter 5, Part 2. This is the only path for a non-relative when the parent is unavailable. You petition the District Court. Unless the court limits the appointment, a guardian 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.

Court guardianship involves filing fees (fee waivers are available for those who qualify), a hearing, and a timeline measured in weeks rather than minutes. It's a heavier process, but it provides stronger and more permanent authority than any out-of-court instrument.

The Gap Between Relationship and Legal Standing

The frustrating reality for family friends is that Montana law prioritizes biological and legal family connections over functional caregiving relationships. A godmother who has known a child since birth and taken them in during a crisis has less legal standing than a distant cousin by marriage who the child has never met.

This isn't unique to Montana — most states draw the same line — but it creates real problems when schools and doctors need someone with legal authority and the person doing the actual parenting doesn't have it.

The fastest fix is getting the parent to sign a POA. If that's not possible, start the guardianship petition early rather than trying to navigate months of school and medical appointments with no legal authority.

Benefits Access

For both relatives and family friends, the child may qualify for Healthy Montana Kids health coverage and TANF Child-Only cash grants regardless of the caregiver's income — those programs evaluate the child's income independently. Apply at apply.mt.gov or through a local Office of Public Assistance.
