Probate in Idaho: A Complete Guide

Idaho has adopted the Uniform Probate Code and offers one of the more streamlined "informal probate" processes in the country. Idaho is also one of nine community property states, which changes how assets pass between spouses in ways that surprise a lot of families. This guide walks through every Idaho probate path — informal probate, formal probate, supervised administration, and the small estate affidavit — so you know which applies to yours.

Does Idaho Always Require Probate?

No. Assets that pass outside of probate in Idaho include those held in a revocable living trust, accounts with payable-on-death (POD) or transfer-on-death (TOD) registrations, securities registered in TOD beneficiary form under Idaho's Uniform TOD Security Registration Act, life insurance and retirement accounts with named beneficiaries, joint tenancy property with right of survivorship, and — for married couples — real property held as community property with right of survivorship.

Community Property in Idaho

Idaho is one of nine community property states. Most property acquired during marriage is owned 50/50 by both spouses regardless of whose name is on the title. When one spouse dies, the surviving spouse already owns half of the community property outright — only the deceased spouse's half passes through probate (Idaho Code § 15-2-102).

Idaho also allows married couples to title real estate specifically as community property with right of survivorship (Idaho Code § 15-6-401), a designation the legislature created in 2008. When a deed expressly states this form of ownership, the surviving spouse automatically receives full title on the first spouse's death — no probate needed for that property at all.

The Idaho Small Estate Affidavit ($100,000)

For estates with a total value — after deducting liens and encumbrances — of $100,000 or less, Idaho allows a Small Estate Affidavit (Idaho Code § 15-3-1201). The affidavit can be used 30 days after death and is presented directly to whoever holds the asset (a bank, a transfer agent, etc.) — no court filing is required. To use it, no petition for a personal representative or summary administration can already be pending, and the person signing must be the decedent's rightful successor. Note this affidavit only reaches personal property (bank accounts, securities, vehicles) — it cannot transfer title to real estate.

The Three Tracks of Idaho Probate

• Informal probate: Idaho's preferred path. Handled administratively by the Magistrate Division of the District Court, without a hearing. Letters are typically issued within a few weeks.
• Formal probate: Required when there's a will contest, the will's validity or terms are unclear, or another dispute needs a judge's decision.
• Supervised administration: The court actively supervises every significant step of administration — the slowest and most expensive track, reserved for contested or complicated estates.

How to Open Informal Probate in Idaho

1. File an Application for Informal Probate of Will and Informal Appointment of Personal Representative in the Magistrate Division of the District Court in the county where the deceased was domiciled.
2. The Magistrate's office reviews the application administratively — usually within a few weeks, with no court hearing required.
3. Once approved, the court issues Letters Testamentary (with a will) or Letters of Administration (without one), giving you legal authority to act for the estate.

Idaho Personal Representative Compensation

Idaho allows "reasonable compensation" (Idaho Code § 15-3-719) — there is no statutory percentage. In practice, compensation typically runs 1–4% of estate value, scaled to the estate's complexity and the actual time required. A will can also set its own compensation terms, which the personal representative can accept or renounce in favor of the statutory "reasonable compensation" standard.

Creditor Claims in Idaho

The personal representative may publish a Notice to Creditors once a week for three successive weeks in a newspaper of general circulation in the county. Once published, creditors have 4 months from the date of first publication to present claims (Idaho Code §§ 15-3-801, 15-3-803). Known creditors given direct written notice instead have 4 months from publication or 60 days from the mailed notice, whichever is later. Without any published or direct notice, creditors generally have up to 1 year from the date of death to bring a claim.

Idaho Intestacy: What If There's No Will?

If there's no will, Idaho Code § 15-2-102 controls. Key rules:

• Community property: The decedent's half of all community property passes entirely to the surviving spouse, who already owned the other half.
• Separate property, no descendants: If there's no surviving issue, the spouse takes the entire separate estate (or half if a parent also survives).
• Separate property, with descendants: The spouse takes half of the separate property; the decedent's descendants take the other half.

Idaho Has No State Estate or Inheritance Tax

Idaho levies no state estate tax and no inheritance tax. Only very large estates need to worry about the federal estate tax exemption.
