Overview

Blaine County is located in Montana with a population of approximately 7,044. The 17th Judicial District Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Montana probate is governed by Title 72 of the Montana Code Annotated (MCA). The process begins with filing an Application for Informal Probate and Appointment of Personal Representative to admit the will and appoint a personal representative. The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

Montana offers a simplified procedure for small estates. If the value of the entire estate, less liens and encumbrances, does not exceed $50,000, successors may file an Affidavit for Collection of Personal Property to collect assets without full probate administration.

Montana does not have a statutory fee schedule for attorneys or personal representatives based on a percentage of the estate; fees must be reasonable based on services provided.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Small Estate Affidavit: If the estate is valued at $50,000 or less (after liens), successors can use an affidavit to collect personal property 30 days after death.
  • Non-Probate Transfers: Assets with designated beneficiaries (life insurance, POD accounts) or held in joint tenancy with rights of survivorship bypass probate.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Application

If probate is needed, file an Application for Informal Probate (or Petition for Formal Probate) with the 17th Judicial District Court. Include:

  • Original Last Will and Testament (if applicable)
  • Application for Informal Probate and Appointment of Personal Representative
  • Certified death certificate
  • Filing fee ($100)
  • Proposed Letters and Order

E-filing may be available; check with the Clerk of District Court for current electronic filing options and requirements.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the appointment and/or hearing to all heirs, devisees, and interested parties within 30 days of appointment.
  • Publish notice in a newspaper of general circulation in Blaine County (such as The Blaine County Journal News-Opinion) for three successive weeks to notify creditors.

Step 4: Attend the Hearing

For informal probate, a hearing is typically not required if the application is complete and uncontested. The Clerk can issue Letters immediately. For formal probate, the court will schedule a hearing, typically 14 days or more after filing.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and allow 4 months from the date of first publication for claims to be filed.
  • Inventory and appraise all estate assets within 9 months of appointment.
  • Pay valid creditor claims and estate expenses.
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries.
  • File a Sworn Statement to Close Estate to conclude the process.
