About Bannock County
Bannock County is Pocatello – southeast Idaho’s largest city and a community whose identity has been shaped by two dominant forces: the Union Pacific Railroad and Idaho State University.
Pocatello (the county seat, population ~55,000) developed as a major railroad junction – the intersection of the Union Pacific mainline with branch lines serving the mining districts of Montana and the agricultural regions of southern Idaho. The railroad’s headquarters functions, repair shops, and classification yards made Pocatello one of the most important railroad cities in the Mountain West in the late 19th and early 20th centuries.
Idaho State University (ISU) (enrollment ~12,000) is a comprehensive research university with particular strengths in pharmacy (the ISU College of Pharmacy is the only pharmacy school in Idaho), health professions, and the natural sciences. The ISU Health Sciences Campus and affiliated Portneuf Medical Center make Pocatello the healthcare hub for a large region of southeast Idaho.
The Oregon and California trails passed through the Bannock County area – the Fort Hall trading post (established 1834 by the Hudson’s Bay Company on the Snake River) was a critical supply point for westward emigrants. The Shoshone-Bannock Tribes (Fort Hall Reservation) are the sovereign tribal nation whose traditional territory encompasses much of southeast Idaho, with the reservation immediately north of Pocatello.
Simplot (J.R. Simplot Company – the agribusiness giant that built much of Idaho’s potato processing empire and was the original McDonald’s French fry supplier) has significant operations in the Pocatello region, as does FMC Corporation (phosphate mining and chemical processing in nearby Soda Springs).
County government is a three-member Board of County Commissioners with separately elected offices for the Assessor, Clerk, Coroner, Prosecuting Attorney, Sheriff, and Treasurer.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Bannock County Magistrate Court (Sixth Judicial District) Bannock County Courthouse, 624 East Center Street, Pocatello, ID 83201-6274 Main: (208) 236-7342; District Court: (208) 236-7350; Magistrate Division: (208) 236-7351
Bannock County is home to Pocatello, where I-15 and I-86 meet, and to Idaho State University. The 1917 Bannock County Courthouse has notable historic architecture.
Step 1: figure out which path applies
Idaho has adopted the Uniform Probate Code (Idaho Code Title 15). Idaho is also a community property state. Idaho recognizes four main paths:
Small Estate Affidavit – a non-court process for estates with a total value of $100,000 or less (excluding liens and encumbrances) and no real property. Available 30 days after death. No court filing required (Idaho Code § 15-3-1201).
Summary Administration – available when the value of all the decedent’s property is less than the homestead allowance, exempt property, and last-illness medical expenses combined, or when a surviving spouse is sole beneficiary (Idaho Code §§ 15-3-1203, 15-3-1205).
Informal Probate – the most common track for uncontested estates, handled through the court registrar.
Formal Probate – court-supervised proceedings required when disputes arise or the will is contested.
Step 2: filing
For informal probate with a will, file an Application for Informal Probate of Will and Appointment of Personal Representative with the Magistrate Division.
For formal probate, file a Petition for Probate of Will and Appointment of Personal Representative (or the equivalent for intestate estates).
Idaho does not have a statutory fee schedule for attorneys or personal representatives – fees must be reasonable given the services rendered and complexity.
If formal or informal probate is needed
Determine whether small estate affidavit, summary administration, or full probate applies.
File the appropriate application or petition with the Bannock County Magistrate Court.
Under informal proceedings, the registrar reviews the application without a hearing. Under formal proceedings, a judge holds a hearing.
The personal representative accepts the appointment and may need to post a bond.
Once appointed, the court issues Letters Testamentary or Letters of Administration. Obtain several certified copies.
Publish notice to creditors as required.
Mail notice to all heirs, beneficiaries, and interested parties.
Marshal assets, obtain an EIN, open an estate account, pay valid debts and expenses, and prepare any required inventory.
Distribute remaining assets per the will or Idaho’s intestacy statutes, then close the estate.
What it costs
Idaho does not impose its own state estate or inheritance tax.
Idaho does not have a statutory fee schedule for attorneys or personal representatives.
Court filing fees and publication costs are separate – confirm current amounts with the Bannock County Magistrate Court.
Probate in Idaho typically takes 6-12 months for uncontested estates.
