Limited Guardianship vs Full Guardianship Montana

How Montana Law Defines the Two Types

Montana's guardianship statute starts from a clear principle: guardianship must be ordered only to the extent required by the person's actual limitations. Under MCA § 72-5-306, a guardianship must be designed to encourage the development of maximum self-reliance and independence.

Limited guardianship grants the guardian authority over specific, enumerated domains — and nothing else. The court order lists exactly which decisions the guardian can make (for example, medical consent and residential placement) and explicitly states that the ward retains all other rights. A limited guardian cannot act beyond the powers stated in the order.

Full (plenary) guardianship transfers all personal decision-making authority to the guardian. The ward loses the right to choose where they live, consent to or refuse medical treatment, enter into contracts, direct their education, and in the most restrictive cases, marry or vote. Full guardianship effectively makes the guardian a substitute decision-maker across every domain of the ward's life.

What the Court Must Find Before Appointing Either

Under MCA § 72-5-316, a Montana district court cannot appoint a guardian of any type unless it makes specific findings:

1. The respondent is an "incapacitated person" as defined by MCA § 72-5-101 — meaning they lack sufficient understanding to make or communicate responsible decisions regarding their person
2. Less restrictive alternatives (supported decision-making, powers of attorney, representative payee, and other voluntary instruments) have been tried or are demonstrably insufficient
3. The guardianship is the least restrictive form of intervention consistent with the person's actual needs

That third requirement is why courts should default to limited guardianship whenever the evidence supports it. If a young adult can manage their own finances through a durable POA and representative payee arrangement but cannot understand medical treatment options well enough to provide informed consent, the court should limit the guardianship to healthcare decisions — not grant a blanket order that also covers finances, residence, and education.

What the Ward Keeps Under Each Type

Under both types, Montana law (MCA § 72-5-306) states that a person under guardianship is not presumed incompetent and retains all civil and political rights not explicitly limited by the court order. This is a critical distinction from some other states that treat full guardianship as a blanket finding of incompetence.

How to Request Limited Guardianship in Your Petition

The petition for guardianship (filed under MCA § 72-5-319) must specify which rights you are asking the court to limit and which areas you are requesting the guardian to oversee. Families seeking a limited guardianship should:

Be specific about the domains. Instead of requesting general authority over "personal care," list the exact categories: "authority to consent to medical treatment and select healthcare providers" or "authority to determine residential placement."

Document what works without court authority. The petition must describe the less restrictive alternatives that have been attempted. If the young adult successfully manages daily finances through a durable POA and representative payee, state that clearly — it supports the argument that financial authority should stay with the young adult rather than being transferred to a guardian.

Request that the order preserve specific rights. You can ask the court to include affirmative language in the order stating which rights the ward retains, not just which rights are transferred.

When Full Guardianship Is the Right Answer

Full guardianship is appropriate when a young adult's cognitive impairment is severe and pervasive enough that they cannot safely make any category of personal decisions, even with support. This typically applies to individuals who:

• Cannot understand the basic concept of a power of attorney or supported decision-making agreement
• Face active exploitation or self-harm risks across multiple domains simultaneously
• Have been clinically evaluated as unable to participate meaningfully in any form of collaborative decision-making

Even in full guardianship cases, Montana law requires the guardian to actively encourage the ward's development toward self-reliance. The guardian must file a Care Plan within 90 days of appointment and annual well-being reports that demonstrate how they are supporting the ward's independence — full guardianship is not meant to be a permanent, static arrangement.

The Modification Path — Moving from Full to Limited

If a young adult under full guardianship develops skills and capacity over time, any interested person (including the ward themselves) can petition the court under MCA § 72-5-325 to modify the guardianship from full to limited, or to terminate it entirely. The court will appoint a visitor to investigate and hold a hearing, and the ward has the right to independent legal counsel throughout the process.
