Overview

Jefferson County is located in Montana with a population of approximately 13,304. The 5th 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 the Montana Code Annotated (MCA) Title 72. The process begins with filing a Petition for Probate 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 use an Affidavit for Collection of Personal Property to collect assets without full court administration, provided at least 30 days have passed since the death.

Montana does not have a statutory fee schedule for attorneys or personal representatives; fees must be reasonable based on the 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 (less liens) is valued at $50,000 or less, you may be able to use an affidavit to collect assets 30 days after death.
  • Non-Probate Transfers: Assets with designated beneficiaries (life insurance, POD accounts) or held in joint tenancy with rights of survivorship do not go through probate.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal probate is needed, file a Petition for Probate with the 5th Judicial District Court. Include:

  • Petition for Probate (Formal or Informal)
  • Original Will and codicils (if any)
  • Certified Death Certificate
  • Filing fee ($100.00)
  • Proposed Order and Letters

Jefferson County participates in the Montana Courts E-Filing system (available for attorneys only).

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing (if formal) or notice of appointment (if informal) to heirs and devisees at least 14 days before the hearing.
  • Publish notice to creditors in a newspaper of general circulation in Jefferson County (such as the Boulder Monitor) once a week for three successive weeks.

Step 4: Attend the Hearing

For formal probate, the court will schedule a hearing. If the petition is informal and uncontested, the Clerk may issue Letters without a hearing upon review of the documents.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors (creditors have 4 months from first publication to file claims)
  • 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 Final Account and petition for discharge to close the estate
