How do I name a guardian for my children in Montana?

Name your preferred guardian in your will [§ 72-5-211]. The court is not bound by your nomination, but it carries significant weight. Name a backup guardian in case your first choice is unable or unwilling to serve.

What happens if I don't name a guardian?

The court decides who will raise your children, based on the best interests of the child. Family members may petition, and if they disagree, the resulting litigation is expensive, stressful, and public.

What is the difference between guardianship and power of attorney?

A power of attorney is voluntary — you choose your agent while you have capacity. Guardianship is court-imposed after incapacity, when no POA exists. Guardianship is more expensive, slower, and involves ongoing court oversight [§ 72-5-316; 72-5-409].

Can I avoid guardianship with estate planning?

Yes. A durable financial power of attorney and a designee handle the two main areas where guardianship would otherwise be needed. Proper estate planning is the single best way to avoid a guardianship proceeding.

What does "guardian and conservator" mean in Montana?

Montana uses the term "guardian and conservator" to refer to a court-appointed person who makes decisions for someone who cannot do so themselves — either a minor child or an incapacitated adult [§ 72-5-316; 72-5-409].

Montana Guardianship for Minor Children — How to File

Nominating a guardian for your children — what happens if you don't, and how to plan ahead.

Guardianship planning ensures that if something happens to you, the people who depend on you — especially minor children — are cared for by someone you trust. In Montana, the court uses the term "guardian and conservator" §72-5-211.

Guardianship for minor children §72-5-211

Your will is the primary way to nominate a guardian for your minor children. Without a nomination, the court decides — and the process can be contentious if family members disagree.

How guardian nomination works

Nominate in your will

Name your preferred guardian (and a backup) in your will §72-5-211. This does not guarantee appointment, but courts give substantial weight to a parent's nomination.

Court reviews the nomination

If both parents die or become incapacitated, the court reviews the nomination and confirms the guardian if the appointment serves the child's best interests.

Guardian assumes responsibility

The appointed guardian has legal authority over the child's person — daily care, education, medical decisions, and living arrangements.

💡Naming a guardian in your will is different from naming a property guardian or custodian for assets you leave to the child. Consider who will manage the child's inheritance separately from who will raise the child — these can be different people.

Guardianship for incapacitated adults §72-5-316; §72-5-409

When an adult can no longer manage their own affairs and has no Power of attorney or other advance planning in place, a family member or interested party can petition the court for guardian and conservator §72-5-316; §72-5-409.

Why guardianship is a last resort

It requires a court proceeding with legal fees and ongoing reporting
The incapacitated person loses legal rights — the court, not the family, decides who serves
The guardian must file periodic reports and accountings with the court
It is public — anyone can access guardianship records

A Power of attorney and designee, created while you have capacity, avoid the need for guardianship entirely. These documents let you choose your own agent privately and without court involvement.

Guardian vs. conservator

	Guardian of the person	Conservator / guardian of the estate
Scope	Personal decisions — housing, medical care, daily needs §72-5-316; §72-5-409	Financial decisions — assets, bills, investments
Who needs it	Someone who cannot make personal decisions	Someone who cannot manage finances
Court oversight	Periodic reports on the person's well-being	Financial accountings filed with the court
Can be same person	Yes — the court may appoint one person for both roles	Yes, but splitting responsibilities is sometimes better

Montana follows the Uniform Probate Code framework for guardianship and conservatorship. A parent may appoint by will a guardian of an unmarried minor; subject to the minor's rights, the appointment becomes effective when the guardian files an acceptance in the court where the will is probated, if both parents are dead or the surviving parent has been adjudged incapacitated (MCA § 72-5-211). For incapacitated adults, a court may appoint a guardian only if the person is incapacitated, the person's identified needs cannot be met by a less restrictive alternative, and judicial intervention is necessary to meet essential requirements for physical health or safety (MCA § 72-5-316). A conservator may be appointed if the person is unable to manage property and affairs effectively and the property will be wasted or dissipated, or funds are needed for the person's support, without proper management (MCA § 72-5-409).

✓The best way to avoid guardianship is to have a complete estate plan: a financial power of attorney, healthcare directives, and (if applicable) a guardian nomination in your will. These documents are simpler, cheaper, and more private than any court proceeding.
