Roads & Utilities
ROADS & TRANSPORTATION
Roads: I-15/SR-37 serve Malad City, the county seat, in a small valley in southeastern Idaho.
Notes: Oneida County was formed in 1864, named for the Oneida people of New York, reflecting the origin of some early settlers. Oneida County was originally enormous – Idaho’s largest county by both area and population, at 32,708 square miles, the third-largest of the 17 counties created by Idaho Territory’s first legislature – before losing territory to the new Montana Territory in 1864, still leaving it the state’s largest remaining county at 20,621 square miles. The county seat was originally Soda Springs, where General Patrick Edward Connor had established Fort Connor in 1863; it moved to Malad City in 1866 due to Malad’s population growth and strategic position on the freight and stagecoach route between Corinne, Utah, and the mines of Butte, Montana.
Business & Permits
BUILDING & PERMITS
Office: Oneida County Courthouse – Malad City, ID.
Notes: Malad City is genuinely notable as one of the most distinctively Welsh communities in the United States: founded by Welsh Mormon pioneer settlers beginning in 1864, the town claims the largest per-capita concentration of Welsh ancestry outside Wales itself. Early town-meeting minutes were reportedly recorded in both English and Welsh, and the community celebrates this heritage annually with the Malad Valley Welsh Festival, including historic wagon rides and family history displays. The town’s name derives from the French word for “ill,” reflecting travelers’ reported sickness after drinking from local springs in the area’s earliest days. The historic Oneida Wagon Road (also called the “Gold Road”), a toll route between Malad and Blackfoot, was notorious for stagecoach robberies targeting shipments of Montana gold; local legend holds that some robbers’ loot remains hidden behind an iron door in the nearby Samaria Mountains, never recovered.

About Oneida County County
Oneida County is southeast Idaho’s Malad River canyon and Bear River Range mountain ranching county – the basalt river canyon whose French fur trapper name tells a story and the traditional Latter-day Saint ranching community in the mountains near Utah define a county where Malad City serves the surrounding agricultural families near the Utah border.
Malad City (the county seat, population ~2,100) is Oneida County’s governmental hub on I-15, a southeast Idaho community near Utah whose Malad River canyon, Bear River Range hunting, and Latter-day Saint heritage anchor its identity as Idaho’s southernmost I-15 community.

Oneida County was one of the first counties organized in Idaho Territory (January 1864), in far southeastern Idaho near the Utah border.
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 Oneida 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 Oneida County Magistrate Court.
Probate in Idaho typically takes 6-12 months for uncontested estates.
