Overview

Franklin County is located in Idaho with a population of approximately 15,000. The Franklin 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 Title 15 of the Idaho Statutes (Uniform Probate Code). The process begins with filing an Application for Informal Probate and Appointment of Personal Representative (Form CAO Pb 01) 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 Small Estate Affidavit procedure for estates consisting solely of personal property valued at $100,000 or less (Idaho Code § 15-3-1201). There is also a summary administration procedure available when a surviving spouse is the sole beneficiary.

Idaho does not have a statutory fee schedule for attorneys or personal representatives; fees must be reasonable based on the services performed.

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 to collect assets without court administration.
  • Summary Administration: A simplified process available when the surviving spouse is the sole 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 an Application for Informal Probate (Form CAO Pb 01) with the Franklin County Magistrate Court. Include:

  • Application for Informal Probate and Appointment of Personal Representative
  • Original Last Will and Testament (if applicable)
  • Certified copy of the Death Certificate
  • $166.00 filing fee
  • Renunciations or Nominations from other heirs (if applicable)

Idaho courts utilize the iCourt system for e-filing, which is mandatory for attorneys and optional for self-represented litigants in some counties.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the appointment to all heirs, beneficiaries, and interested parties within 30 days of appointment.
  • Publish notice in a newspaper of general circulation in Franklin County for three successive weeks to notify creditors.

Step 4: Attend the Hearing

For informal probate, a hearing is typically not required if all paperwork is in order. If formal probate is requested, the court will schedule a hearing, typically 2 to 4 weeks after filing. At the hearing, the judge reviews the petition and, if approved, issues Letters Testamentary or Letters of Administration.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Publish notice to creditors once a week for three successive weeks. Creditors have 4 months from the date of first publication to file claims.
  • Inventory and appraise all estate assets within 3 months of appointment.
  • Pay valid creditor claims.
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries.
  • File a final accounting and petition for discharge or closing statement.
