Overview

Twin Falls County is located in Idaho with a population of approximately 96,509. The Twin Falls 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 (Application for Informal 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.

Idaho offers a simplified procedure for small estates called the Affidavit Collecting Personal Property of Decedent. This can be used if the fair market value of the entire estate (less liens and encumbrances) does not exceed $100,000 and no application for appointment of a personal representative is pending or has been granted.

Idaho does not have a statutory fee schedule for attorneys or executors; fees are typically "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 of personal property valued at $100,000 or less, you may be able to use an affidavit 30 days after death.
  • Survivorship: Assets held in joint tenancy with right of survivorship pass directly to the survivor.
  • 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 Twin Falls County Magistrate Court. Include:

  • Application for Informal Probate of Will and/or Appointment of Personal Representative
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee ($166.00)
  • Renunciations/Nominations from other heirs (if applicable)

Idaho courts utilize the iCourt system for case management. Check with the clerk regarding mandatory e-filing requirements for attorneys.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing (or appointment) to all heirs, beneficiaries, and interested parties within 30 days of appointment.
  • Publish notice to creditors in a newspaper of general circulation in Twin Falls County (such as the Times-News) once a week for three successive weeks.

Step 4: Attend the Hearing

For informal probate, a hearing may not be required if the registrar approves the application. For formal probate, the court will schedule a hearing. Upon approval, the court issues Letters Testamentary or Letters of Administration.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

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