Overview

Sanders County is located in Montana with a population of approximately 13,900. The Montana 20th 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 Montana Code Annotated (MCA) Title 72. The process begins with filing a Petition for Probate of Will and Appointment of Personal Representative (or Petition for Adjudication of Intestacy) 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.

Small Estate Affidavit: Montana offers a simplified procedure for estates valued at $50,000 or less (less liens and encumbrances). Successors may file an Affidavit for Collection of Personal Property 30 days after death to collect assets without full probate administration.

Fees: Montana law sets reasonable compensation for personal representatives and attorneys, but does not mandate a specific statutory percentage. Fees are typically based on time spent and the complexity of the estate.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Small Estate Affidavit: If the estate's value (less liens) is $50,000 or less, you may use an affidavit 30 days after death to collect personal property.
  • Non-Probate Transfers: Assets with designated beneficiaries (life insurance, POD accounts) or held in joint tenancy with right of survivorship transfer outside of 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 Sanders County District Court. Include:

  • Original Will (if applicable)
  • Certified Death Certificate
  • Application for Informal Probate or Petition for Formal Probate
  • Order Appointing Personal Representative
  • Letters Testamentary or Letters of Administration
  • Filing fee ($100)

Electronic filing may be available; check with the Clerk of Court for current e-filing protocols.

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 Sanders County (e.g., Sanders County Ledger) once a week for three successive weeks.

Step 4: Attend the Hearing

For informal probate, a hearing is often not required if paperwork is in order. For formal probate, the court will schedule a hearing to review the petition. Upon approval, the Clerk issues Letters authorizing the Personal Representative to act.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors (creditors have 4 months from the date of 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 according to the Will or state intestacy laws.
  • File a Verified Statement of Closing or petition for a formal closing order to discharge duties.
