Montana Power of Attorney for a Minor Child

What a Minor Power of Attorney Does

Montana's Minor Power of Attorney under MCA 72-5-103 lets a parent delegate care, custody, educational, and medical authority for their child to another adult. It's the broadest out-of-court delegation Montana offers — covering both school and healthcare decisions in a single document.

The key distinction from the caretaker relative affidavits: a POA requires the parent's signature. That makes it the right choice when the parent is available and cooperative but temporarily can't handle day-to-day parenting — scheduled medical treatment, voluntary rehabilitation, short-term work deployment, or a jail sentence where the parent has access to mail and notary services.

Who Can Receive a POA

Anyone. Unlike the statutory affidavits, which are limited to blood, marriage, or adoption relatives, a power of attorney under MCA 72-5-103 can name any adult as the attorney-in-fact. That includes grandparents, aunts, uncles, and adult siblings, but also family friends, neighbors, coaches, or anyone the parent trusts.

This is the only out-of-court option for non-relative caregivers when the parent is available to sign. Without it, a family friend caring for a child would need to petition for court-ordered guardianship.

The Six-Month Cap

A Montana minor POA expires after six months. If the parent's absence extends beyond that window, you need a newly executed POA before the old one lapses.

The six-month 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. For everyone else, the cap is firm.

How to Execute It

The parent (or legal guardian) signs the POA, naming the specific adult who will serve as attorney-in-fact and listing what powers are delegated. Notarization is not required for execution, but under MCA 72-31-305, acknowledging the signature before a notary makes it presumptively genuine. The document should identify the child by full legal name and date of birth, specify the scope of authority (care, custody, educational decisions, medical decisions, property management), and include the date it takes effect and when it expires.

Unlike the caretaker affidavits, there's no single statutory form template printed in the Montana Code for this POA. The parent can draft one or use a template that covers the elements MCA 72-5-103 requires.

What a POA Cannot Do

Two things are explicitly excluded: consent to marriage and consent to adoption. A POA also cannot permanently alter parental rights. The parent retains the ability to revoke it at any time.

For major medical decisions — elective surgery under general anesthesia, inpatient psychiatric admission — a POA provides broader authority than the medical affidavit, since it delegates whatever powers the parent chooses to include. But even a POA doesn't override the statutory restrictions on marriage and adoption consent.

POA vs. Affidavit — When to Use Which

Use the POA when: the parent is reachable and willing to sign, or the caregiver is a non-relative. It covers both school and medical authority in one document.

Use the affidavits when: the parent is absent, unreachable, or unwilling to cooperate. The caretaker must be a relative by blood, marriage, or adoption. You'll need two separate affidavits — one for school (MCA 20-5-503) and one for medical (MCA 40-6-502).

Use both when: the POA has ended and each affidavit's separate eligibility requirements are met. While a POA is in effect, it is an adequate provision for the child's care, so the affidavits are not available as a parallel backup. An expired or revoked POA alone does not qualify you to use them.
