Divorce records are NOT in the County Recorder's Office, they are in the County Clerk's Office, 151 W. 1st North, Saint Anthony, ID, 83445, (208) 624-7332. Court Clerks record COURT actions.
--The County Clerk and Recorder has the marriage records, same address, room 12, phone 208-624-3148. County recorder records deeds, liens, marriages, power-of-attorney, etc.
