How to File a Guardianship Petition in Montana

Your parent can no longer manage their own affairs. They did not sign a power of attorney while they still had capacity, and now a bank, hospital, or care facility is telling you that you have no legal authority to act on their behalf. The only path forward is a guardianship petition through Montana District Court.

This is not a quick process. It typically takes 30 to 60 days from filing to hearing, involves mandatory professional evaluations, and costs between $3,000 and $7,000 when attorney fees are included. But understanding each step before you begin can save you delays, rejected filings, and unnecessary expense.

Step 1: Determine the Correct Court

File the petition in the District Court of the county where your parent currently resides or is physically present. If your parent lives in Yellowstone County but was hospitalized in Gallatin County, you generally file in Yellowstone County — their county of residence.

Step 2: Prepare the Petition

The petition is a formal written request asking the court to appoint you (or another suitable person) as guardian. Montana District Courts provide standardized forms through the Montana Supreme Court Commission on Self-Represented Litigants at courts.mt.gov/forms/guardianship.

The petition must include:

• Your parent's full legal name, date of birth, and current address
• A description of why your parent needs a guardian — the specific cognitive or physical limitations that prevent them from making reasonable decisions
• The name and relationship of the person you are asking the court to appoint as guardian
• A list of all "interested parties" — your parent's spouse, all adult children, parents (including divorced/separated nonresidential parents), and any person or institution currently providing care

Step 3: File and Pay the Filing Fee

The standard filing fee across Montana District Courts is $100 (Yellowstone, Missoula, Gallatin, Flathead, and other major counties). If your parent is low-income or receives Medicaid, SSI, or other public benefits, you can request a fee waiver by submitting an Affidavit of Inability to Pay Filing Fees — also available from the court's self-help forms.

Step 4: Serve Notice on All Interested Parties

This is where many families stumble. Montana law requires that every interested party receive written notice of the guardianship hearing at least 14 days before the scheduled date. Notice must go to:

• Your parent (the alleged incapacitated person)
• Your parent's spouse
• All adult children
• Your parent's living parents, including any divorced or separated nonresidential parent
• Any person or institution currently providing care or housing

Notice can be delivered by certified mail with return receipt or by personal service. If an interested party cannot be located after reasonable effort, you must publish notice in a local newspaper — adding approximately $200 to your costs.

Critical warning: Failing to notify a legally required party will void the entire proceeding. If you have a divorced parent you have not spoken to in decades, you still must serve them with notice.

Step 5: Court-Appointed Professionals

Once the petition is filed and the hearing is scheduled, the court appoints three individuals to protect your parent's rights:

Court-appointed attorney. Your parent has an absolute right to legal representation. If they do not have their own attorney, the court appoints one to advocate for your parent's expressed wishes — even if those wishes conflict with what you believe is best.

Appointed physician. A licensed physician must examine your parent and submit a written medical capacity report. This report details the parent's physical and mental diagnoses and explains why a guardian is clinically necessary.

Court visitor. An independent professional — trained in social work, law, nursing, or rehabilitation — interviews your parent, interviews you (the proposed guardian), and inspects both the parent's current living situation and any proposed changes. The visitor files a written report with the court evaluating whether guardianship is appropriate and whether you are a suitable guardian.

The judge cannot sign the guardianship order until both the physician's report and the court visitor's evaluation have been formally received and accepted.

Step 6: Attend the Hearing

The hearing is typically scheduled 30 to 60 days after filing. You must appear in person. Your parent has the right to attend and to testify. The court-appointed attorney may cross-examine you or present evidence on your parent's behalf.

If the judge finds clear and convincing evidence that your parent is incapacitated and that no less restrictive alternative exists, the court issues Letters of Guardianship. Certified copies cost $2 to $3 each — get several, because banks, medical providers, and government agencies will each want their own certified copy.

Less Restrictive Alternatives

Montana courts follow the Uniform Guardianship, Conservatorship, and Other Protective Arrangements Act (UGCOPAA), which requires judges to consider less restrictive alternatives before granting a full guardianship. The court will ask whether a power of attorney, supported decision-making agreement, or technological assistance could serve your parent's needs without removing their civil rights. Be prepared to explain why these alternatives are insufficient.

The Montana Power of Attorney & Guardianship Kit includes a petition preparation checklist, a timeline tracker for the entire court process, and guidance on what the court visitor and judge will expect from you during the hearing.
