Idaho court records index for all 44 counties is online at the Idaho State Judiciary, Supreme Court Data Repository. Search by partial name for records from 1995 forward (some older cases may be available, according to the court Web site). The search form suggests that date of birth is a required field, but I found that a search by name only worked.
The index lists party names, city and state of residence, county of filing, case numbers, charges (or case type, in civil filings), filing or violation date, disposition and register of actions. Year of birth is listed on criminal cases. If a case has been sealed, that is noted. The cases are sorted by county. If there’s more than one case for that person in the selected county those are all listed on one page.
