Overview

Sweet Grass County is located in Montana with a population of approximately 3,700. The Montana Sixth 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, Title 72. The process begins with filing an Application for Informal Probate or a Petition for Formal 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 using an Affidavit for Collection of Personal Property if the entire estate value, less liens and encumbrances, does not exceed $50,000.

Montana law allows for reasonable compensation for personal representatives and attorneys, which must be approved by the court if not specified in the will or agreed upon by the parties.

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 (less liens and encumbrances), you may be able to use an Affidavit for Collection of Personal Property after a 30-day waiting period.
  • Non-Probate Transfers: Assets with designated beneficiaries (POD/TOD accounts, life insurance) or held in joint tenancy with right of survivorship bypass probate.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Application or Petition

If formal or informal probate is needed, file the appropriate Application for Informal Probate or Petition for Formal Probate with the Sweet Grass County District Court. Include:

  • Original Will (if applicable)
  • Certified copy of the Death Certificate
  • Filing fee (approximately $100)
  • Proposed Order and Letters

Step 3: Provide Notice

After filing, you must:

  • Mail notice to all heirs, devisees, and interested parties within 30 days of appointment.
  • Publish notice to creditors in a newspaper of general circulation in Sweet Grass County (such as the Big Timber Pioneer) once a week for three successive weeks.

Step 4: Administration

The court (or Clerk in informal proceedings) reviews the application. Once appointed, the Personal Representative receives Letters.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and allow the 4-month claim period to run
  • 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
  • Close the estate by filing a Sworn Statement to Close Estate or a petition for a formal closing decree
