Overview

Big Horn County is located in Montana with a population of approximately 13,124. The Big Horn County District Court (22nd Judicial District) 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 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 file a Small Estate Affidavit (Affidavit for Collection of Personal Property) 30 days after the decedent's death to collect assets without full probate administration.

Montana law allows for reasonable compensation for personal representatives and attorneys, which may be based on a fee schedule or hourly rates depending on 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 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 (POD/TOD accounts, life insurance) or held in joint tenancy with rights of survivorship pass directly to the co-owner or beneficiary.
  • 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 Big Horn County District Court. Include:

  • Original Last Will and Testament (if applicable)
  • Certified copy of the Death Certificate
  • Application for Informal Probate or Petition for Formal Probate
  • Filing fee (approximately $100)
  • Proposed Order and Letters

Montana courts generally allow for both informal (administrative) and formal (judicial) probate proceedings. E-filing is available through the Montana Courts E-Filing system.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing (for formal probate) or notice of appointment (for informal probate) to all heirs, devisees, and interested parties.
  • Publish notice to creditors in a newspaper of general circulation in Big Horn County, such as the Big Horn County News, once a week for three successive weeks.

Step 4: Attend the Hearing

For formal probate, the court will schedule a hearing. Informal probate is often handled by the Clerk of Court without a hearing if all paperwork is in order. Once approved, the court issues Letters Testamentary or Letters of Administration.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and allow 4 months 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 according to the Will or state intestacy laws
  • File a Sworn Statement to Close Estate or petition for a formal closing decree
