Overview

Butte County is located in Idaho with a population of approximately 2,735. The Butte County Magistrate Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Idaho probate is governed by the Uniform Probate Code (Title 15). The process begins with filing a Petition for Probate of Will and Appointment of Personal Representative (Form CAO Pb 10) 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.

Idaho offers a simplified procedure for small estates. If the decedent's estate consists entirely of personal property valued at $100,000 or less, successors may use a Small Estate Affidavit (Affidavit for Collection of Personal Property) to collect assets without formal court administration, provided at least 30 days have passed since the death.

Idaho 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 consists only of personal property valued at $100,000 or less, you may use an Affidavit for Collection of Personal Property after a 30-day waiting period.
  • Survivorship/Beneficiary Designations: Assets with named beneficiaries (POD/TOD accounts, life insurance) or held in joint tenancy with right 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 of Will and Appointment of Personal Representative (Form CAO Pb 10) with the Butte County Magistrate Court. Include:

  • Original Last Will and Testament (if applicable)
  • Certified copy of the Death Certificate
  • Filing fee of $166.00
  • Application for Informal Probate (if proceeding informally)

Idaho allows for both Informal (administrative, less court supervision) and Formal (judicial, hearing required) probate proceedings.

Step 3: Provide Notice

After filing and appointment, you must:

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

Step 4: Attend the Hearing

For formal probate, the court will schedule a hearing on the petition. At the hearing, the judge reviews the petition and, if approved, issues Letters Testamentary or Letters of Administration. Informal probate typically does not require a hearing if the application is in order.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Inventory and appraise all estate assets within 3 months of appointment.
  • Pay valid creditor claims (creditors generally have 4 months from publication to file claims).
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries.
  • File a Statement of Closing or petition for final discharge to close the estate.
