Overview

Montana adopted the Uniform Probate Code (UPC) under Montana Code Annotated, Title 72, making its probate system standardized and efficient. Probate cases are handled by the district courts in each county.

Montana offers several probate options:

  • Small Estate Affidavit — for estates with total property valued at $50,000 or less, allowing collection of personal property without opening a probate case (available just 5 days after death)
  • Summary Administration — a streamlined court process for estates valued at $100,000 or less
  • Informal Probate — the most common track for uncontested estates, handled with minimal court involvement
  • Formal Probate — court-supervised proceedings for contested or complex estates

Montana does not impose a state estate tax or inheritance tax, which simplifies administration for most families. Only the federal estate tax applies for very large estates.

Montana's small estate affidavit is notable for its very short 5-day waiting period — one of the shortest in the country.

When Probate is Required

Probate is required in Montana when a decedent owned assets in their sole name that do not transfer automatically at death. Common examples include:

  • Real property titled solely in the decedent's name or as tenants in common
  • Bank accounts and investments without payable-on-death (POD) or transfer-on-death (TOD) designations
  • Vehicles and titled personal property in the decedent's sole name
  • Business interests including ranch and farm operations
  • Mineral rights held individually

Probate is generally not required for:

  • Joint tenancy property — passes automatically to the surviving joint tenant(s)
  • Beneficiary-designated assets — life insurance, retirement accounts, POD/TOD accounts
  • Property held in a revocable living trust
  • Small estates valued at $50,000 or less — handled with a small estate affidavit

Montana's UPC framework and generous small estate options allow many families to avoid full probate.

Small Estate Options

Montana provides a small estate affidavit process (MCA 72-3-1101) for collecting personal property without formal probate.

Eligibility requirements:

  • The total value of the estate must not exceed $50,000
  • At least 5 days must have passed since the decedent's death (one of the shortest waiting periods in the country)
  • No application or petition for appointment of a personal representative is pending or has been granted

How the process works:

  1. The successor prepares an Affidavit for Collection of Personal Property of Decedent
  2. The affidavit is signed under oath
  3. The completed affidavit is presented directly to banks, financial institutions, or others holding the decedent's property
  4. The institution must release the property to the affiant

Summary administration for estates under $100,000:

For estates valued at $100,000 or less, Montana also offers a summary administration procedure. The personal representative files a closing statement with a sworn statement that the estate qualifies, allowing for a streamlined closing process.

Important limitations:

  • The standard small estate affidavit is primarily for personal property
  • The affiant becomes personally liable for claims and debts up to the value received
  • For real property, formal probate or a trust may be needed

Step-by-Step Process

1. Determine the appropriate probate track

Assess the estate's value and circumstances. Use the small estate affidavit for estates under $50,000. Use summary administration for estates under $100,000. Use informal probate for uncontested estates of any size.

2. File the application or petition

For informal probate, file an application with the district court in the county where the decedent was domiciled. The filing fee is approximately $100. For formal probate, file a petition with the district court.

3. Appointment of personal representative

In informal probate, the court reviews the application and issues Letters appointing the personal representative without a hearing.

In formal probate, the court schedules a hearing and appoints the personal representative after notice.

4. Accept appointment

File the Acceptance of Appointment to formally accept the role.

5. Publish notice to creditors

Publish a Notice to Creditors in a newspaper of general circulation. Creditors have the later of 4 months from first publication or 1 year from the date of death to present claims.

6. Notify known creditors

Mail or deliver written notice to all known creditors.

7. Collect and inventory assets

Gather all estate assets and prepare a comprehensive inventory, including ranch land, livestock, and mineral rights common in Montana estates.

8. Pay debts, claims, and taxes

Review and pay valid creditor claims in priority order. File the decedent's final income tax returns. Montana has no state estate tax.

9. File the closing statement

For informal probate, file a Closing Statement after all debts are paid and assets distributed.

10. Distribute assets to beneficiaries

Distribute remaining assets according to the will or Montana's intestacy laws. Obtain receipts from beneficiaries.
