Montana Guardianship and Conservatorship Petition for Adults with Disabilities

When Guardianship Becomes Necessary in Montana

Montana law presumes that every adult has full legal capacity. That presumption holds even for adults with intellectual or developmental disabilities — it can only be overridden by a court, after a formal hearing, with clear and convincing evidence that the individual cannot make or communicate decisions even with available supports.

For most families navigating the adult transition, Supported Decision-Making is the right starting point. But SDM has limits. The Montana Supreme Court's 2024 ruling in Matter of Guardianship & Conservatorship of J.F.R. (2024 MT 223) made clear that SDM agreements are not legally sufficient when the individual has severe cognitive impairment, cannot communicate meaningfully even with support, or is vulnerable to financial exploitation that supporters cannot prevent.

If your adult child falls into that category, guardianship or conservatorship may be the only way to protect them.

Guardianship vs. Conservatorship — They Are Separate

Montana law draws a clear line between the two, and you can petition for either or both:

Guardianship (Mont. Code Ann. § 72-5-301 et seq.) gives the appointed guardian authority over personal decisions: medical care, living arrangements, daily activities, and educational choices. The guardian makes decisions the incapacitated person cannot make for themselves.

Conservatorship gives the appointed conservator authority over financial decisions: managing bank accounts, paying bills, handling assets, and making investment decisions. This is the appropriate tool when the primary concern is financial vulnerability rather than personal decision-making.

Many families petition for both simultaneously, but the court evaluates each independently. An individual might need a conservator for finances but retain personal decision-making authority — or vice versa.

The Petition Process

Filing a guardianship or conservatorship petition in Montana involves several steps:

1. File the petition with the district court in the county where the proposed protected person resides. Montana courts provide standardized forms through courts.mt.gov/forms/guardianship. The petition must describe the individual's functional limitations and explain why less restrictive alternatives (SDM, power of attorney, representative payee) are insufficient.

2. The court appoints a visitor. Montana law requires the court to appoint an independent visitor — typically a social worker or mental health professional — to meet with the proposed protected person, evaluate their capacity, and report back to the court. The visitor's role is to ensure the individual's perspective is represented.

3. Attend the capacity hearing. The court holds a hearing where the petitioner must demonstrate, by clear and convincing evidence, that the individual lacks capacity. The proposed protected person has the right to attend, be represented by counsel, and contest the petition. If they cannot afford an attorney, the court may appoint one.

4. The court issues its order. If the court grants the petition, it specifies the scope of the guardian's or conservator's authority. Montana courts are statutorily required to impose the least restrictive form of guardianship necessary — meaning the court may grant authority over some decisions while leaving others with the individual.

Less Restrictive Alternatives the Court Will Consider

Before granting any guardianship, Montana courts must formally evaluate whether less restrictive alternatives would serve the individual's needs. Be prepared to explain why each of these is insufficient:

• Supported Decision-Making — the individual designates supporters to help them understand and communicate decisions, retaining all their own legal rights
• Power of Attorney — the individual grants authority to an agent, but this requires the individual to have legal capacity to execute the document
• Representative Payee — the SSA appoints someone to manage Social Security benefits specifically; this is an administrative process, not a court order
• Limited guardianship — the court restricts the guardian's authority to specific domains rather than granting full control

If you are considering guardianship primarily because the SSA requires someone to manage your child's benefits, a representative payee appointment may accomplish that goal without a court proceeding. The SSA does not recognize guardianship as automatic authority to manage benefits anyway — a representative payee application through the local field office is a separate process regardless.

What Guardianship Costs

The primary costs include:

• Attorney fees: Montana special needs planning attorneys typically charge $250–$500 per hour, with a straightforward guardianship petition running $2,000–$5,000 in total legal fees
• Court filing fees: Vary by county, typically $100–$200
• Visitor costs: The court-appointed visitor's fees are usually paid from the proposed protected person's assets or by the petitioner
• Ongoing reporting: Guardians must file annual reports with the court documenting decisions made on the protected person's behalf; conservators must file annual accountings of all financial transactions

Guardianship and the Adult Benefits Transition

The guardianship petition process takes time — typically 2–4 months from filing to hearing, assuming no contest. If you know guardianship will be necessary, begin the process before your child turns 18 so the order is in place when educational rights transfer and the SSI redetermination arrives.

Timing matters because the IEP transfer of rights happens automatically at 18 regardless of whether a guardianship petition is pending. Without an order in place, the school district will direct all communications to the student during the gap.

The Montana SSI at 18 & Adult Benefits Guide includes a decision framework for choosing between SDM, representative payee, power of attorney, and guardianship — with the full timeline for coordinating the petition alongside the SSI redetermination, DDP application, and Medicaid continuity planning.
