Notes: Kootenai County was established December 22, 1864, named for the Kootenai tribe. It is Idaho’s third-most populous county and the largest in the state’s Panhandle region, accounting for over 45% of North Idaho’s total population.

Office: Kootenai County Courthouse – 501 Government Way, Coeur d’Alene, ID (built 1925-1926, Georgian Revival, architect Julius A. Zittle of Spokane; National Register of Historic Places since 1977).
Notes: Coeur d’Alene was founded in 1879 as a trading post serving nearby Fort Coeur d’Alene (later renamed Fort Sherman), and grew rapidly after the 1883 discovery of lead and silver deposits and the railroad’s 1886 arrival. The area’s mining boom brought genuine, significant national labor history: bitter industrial conflict between mine owners and unionized miners in the 1890s and early 1900s culminated in the 1907 murder trial of union leader William D. “Big Bill” Haywood, secretary-treasurer of the Western Federation of Miners, who was ultimately acquitted following a celebrated defense by famed attorney Clarence Darrow. Coeur d’Alene today serves as headquarters for the Idaho Panhandle National Forests, which include the Kaniksu, Coeur d’Alene, and St. Joe National Forests.

About Kootenai County
Kootenai County is North Idaho’s dominant community – a county whose natural beauty, Idaho’s tax advantages, and proximity to Spokane (just 30 miles west) have made it one of the fastest-growing communities in the Pacific Northwest for two decades.
Coeur d’Alene (the county seat, population ~55,000) sits on the northern shore of Lake Coeur d’Alene – a 25-mile-long glacially-carved lake of extraordinary clarity and scenic beauty, surrounded by forested mountains. The lake is consistently rated among the most beautiful in the United States. The Coeur d’Alene Resort (a landmark lakefront hotel with a famous floating golf green on the 14th hole) anchors a tourism and hospitality economy that draws visitors from the Pacific Northwest year-round.
The Silver Valley – east of Coeur d’Alene in neighboring Shoshone County – was one of the world’s most productive silver mining districts, and the environmental legacy of that mining (the Bunker Hill Superfund Site is one of the largest in the nation) has had complex interactions with Kootenai County’s downstream communities.
North Idaho’s political culture is strongly libertarian and conservative – the region has attracted significant in-migration from California, Oregon, and Washington state by residents seeking lower taxes and less regulation. This migration has driven real estate appreciation dramatically, with Coeur d’Alene home prices rising over 100% from 2019 to 2023 in some submarkets.
North Idaho College (NIC, enrollment ~4,500) is a two-year community college. Lake City Law School (University of Idaho College of Law’s North Idaho extension) provides legal education.
County government is a three-member Board of County Commissioners with separately elected offices for the Assessor, Clerk, Coroner, Prosecuting Attorney, Sheriff, and Treasurer.

Courts & Legal
Courts & Legal
The Kootenai County District Court at 324 W. Garden Avenue, Coeur d’Alene (208-446-1000) handles all civil, criminal, family, and probate matters. The Kootenai County Clerk at the same address (208-446-1616) maintains all court records and land records – searchable online at kcgov.us.
Idaho probate: District Court handles all estate administration. Idaho recognizes Transfer on Death deeds.
Pacific Northwest in-migration estate planning: Kootenai County’s large California and Pacific Northwest in-migrant population needs estate plan updates for Idaho law. Idaho is a community property state – compatible with California’s system but with differences in specific provisions. Washington State in-migrants transitioning from a common law state to Idaho’s community property system need careful review of asset classification.
Lake Coeur d’Alene waterfront succession: High-value lakefront properties – many in the $2-10 million range – require LLC or trust succession planning. Idaho lake properties do not have the tidelands/Corps of Engineers permit issues of some other lake regions, but Idaho Department of Lands regulations govern riparian rights.
Senior Services: The Kootenai County Area Agency on Aging / Community Action Partnership of North Idaho (CAPNI) (208-664-3193) at 702 E. Dalton Avenue, Coeur d’Alene coordinates senior centers, home-delivered meals, transportation, SHIBA Medicare counseling, caregiver support, Adult Protective Services, and connections to Idaho Medicaid long-term care programs.

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
Kootenai County Magistrate Court 324 West Garden Avenue, P.O. Box 9000, Coeur d’Alene, ID 83816-9000
Kootenai County is Idaho’s 3rd-most-populous county and the largest in North Idaho, accounting for 45.4% of the Panhandle region’s population. Established December 22, 1864, named for the Kootenai tribe. The historic 1925-26 Kootenai County Courthouse (Georgian Revival, National Register of Historic Places) still stands at 501 Government Way.
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 Kootenai 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 Kootenai County Magistrate Court.
Probate in Idaho typically takes 6-12 months for uncontested estates.
