Montana Guardianship Co-Guardian: Can Two People Serve as Guardian

When both parents want to serve as guardian for their adult child with a disability, the question of co-guardianship inevitably comes up. Montana law doesn't explicitly prohibit the appointment of co-guardians, but the practical and legal realities make it more complicated than most families expect.

How Co-Guardianship Works in Montana

Montana's probate code under Title 72, Chapter 5 doesn't contain a dedicated co-guardianship statute. What the court can do is appoint multiple individuals to share guardian responsibilities — typically both parents jointly. The court order specifies the scope of each guardian's authority and how decision-making works when the co-guardians disagree.

The challenge is structural. Guardianship gives decision-making authority over critical areas like medical care, residential placement, and service coordination. When two guardians share that authority, every decision potentially requires consensus. Healthcare providers, schools, and service agencies need to know whom to contact — and what happens when one guardian authorizes a medical procedure the other opposes.

When Co-Guardianship Makes Sense

Co-guardianship works best when both proposed guardians are aligned on values, live in the same area, and can communicate consistently about the ward's needs. The arrangement provides natural redundancy — if one guardian is traveling or ill, the other can handle time-sensitive decisions.

For divorced or separated parents who both want guardianship authority, the court weighs whether the co-arrangement will serve the ward's interests or create ongoing conflict. A judge who foresees disagreements undermining the ward's care may appoint one primary guardian instead.

Alternatives to Co-Guardianship

Many families achieve the practical benefits of shared involvement without formal co-guardianship:

One guardian with an emergency backup. The court appoints one parent as guardian. If the primary guardian later cannot serve, the court may appoint a successor under MCA § 72-5-325; the backup does not automatically step into the role. This avoids the consensus problem while planning for continuity.

Guardian plus power of attorney. One parent serves as court-appointed guardian. If the ward has capacity to execute a durable power of attorney and the court order leaves that authority available, the ward can separately name the other parent as financial agent. This divides responsibilities cleanly between personal and financial domains.

Supported decision-making team. Under Montana's SDM framework defined in MCA § 72-5-305, the ward can designate both parents as supporters in a supported decision-making agreement. Combined with appropriate powers of attorney, this gives both parents formal roles without the rigidity of a court order.

Succession Planning

Regardless of whether the court appoints one guardian or two, families should plan for what happens when the guardian can no longer serve. Under MCA § 72-5-325, the court may appoint a successor after a guardian's removal, resignation, death, or incapacity; a successor does not take over automatically.

For families with adult children who may need lifelong support, succession planning is arguably more important than the initial appointment. Siblings, other family members, or professional guardians can serve as successors — but the arrangements should be established formally rather than left to chance.

The Montana Adult Guardianship & Alternatives Guide covers both co-guardianship considerations and the voluntary alternatives that let multiple family members share support responsibilities without court supervision.
