Overview

Bonneville County is located in Idaho with a population of approximately 133,644. The Bonneville 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 of the Idaho Statutes). The process begins with filing a Petition for Probate of Will and Appointment of Personal Representative (if there is a will) or a Petition for Adjudication of Intestacy and Appointment of Personal Representative (if there is no will). The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

Idaho offers a simplified procedure for small estates called the Affidavit for Collection of Personal Property. This is available if the fair market value of the entire estate (less liens and encumbrances) does not exceed $100,000, no application for a personal representative is pending or has been granted, and at least 30 days have elapsed since the death. This procedure cannot be used if the estate includes real property.

Idaho law allows for reasonable compensation for personal representatives and attorneys. There is no statutory percentage fee; fees are typically based on the 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 consists only of personal property valued at $100,000 or less, you may be able to use an affidavit 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 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 the appropriate Petition for Probate with the Bonneville County Magistrate Court. Include:

  • Petition for Probate (Form CAO Pb 01 or similar)
  • Original Last Will and Testament (if applicable)
  • Certified death certificate
  • Filing fee (approximately $166.00)
  • Renunciations or Nominations from other heirs (if applicable)

Idaho courts utilize the iCourt system. Check with the clerk regarding mandatory e-filing requirements for attorneys and self-represented litigants.

Step 3: Provide Notice

After filing and appointment, you must:

  • Mail notice of the appointment to all heirs, beneficiaries, and known creditors within 30 days of appointment.
  • Publish notice to unknown creditors in a newspaper of general circulation in Bonneville County (such as The Post Register) once a week for three successive weeks.

Step 4: Attend the Hearing

For informal probate, a hearing may not be required if all paperwork is in order and uncontested. For formal probate, the court will schedule a hearing to review the petition. Upon approval, the judge or registrar issues Letters Testamentary or Letters of Administration.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Prepare an Inventory and Appraisement of estate assets within 90 days of appointment.
  • Pay valid creditor claims (creditors generally have 4 months from the date of first publication to file claims).
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries according to the will or laws of intestacy.
  • File a Statement of Closing or petition for final distribution to close the estate.

Local Requirements

Bonneville County-Specific Procedures

  • E-filing: Idaho has implemented the iCourt system statewide. Electronic filing is often required for attorneys and available for pro se litigants.
  • Local Rules: The Seventh Judicial District may have specific local rules regarding case management.
