Kootenai County is one of five counties that make up Idaho's First Judicial District. The other four are Benewah, Bonner, Boundary, and Shoshone Counties.

The two main court buildings for Kootenai County are located in the Courthouse Complex at the corner of Government Way and Garden Ave in Coeur d'Alene. See below for courthouse locations.

Deputy court clerks, downstairs in the Justice Building, process all citations, community service enrollment, applications for a public defender, protection orders and filings for all criminal and civil cases.

There are seventeen judges in Idaho's First Judicial District. For more information about jurisdiction and election of the judges, as well as contact information, see the Attorney/Judge Directory.

The state of Idaho is divided into seven judicial districts, each with an Administrative District Judge who is chosen by the other district judges in the district and a Trial Court Administrator (TCA) who is selected jointly by the Administrative District Judge and the Administrative Director of the State Courts.
