Idaho Probate Records
Probate courts had jurisdiction over probate records, adoptions, and minor civil matters until 1971 when they were abolished. Their records were transferred to the magistrate divisions of the district courts. Idaho probate records include wills, appraisals, inventories, letters, claims, final accounts, estate cases and guardianships. The registers and case files are often scattered in various vaults and storage areas in and adjacent to the local courthouse. Some of the records including early case files may have been transferred to the Idaho State Historical Society in Boise.
You can obtain copies of probate records from the clerk's office in each county courthouse. The Family History Library has a few published volumes of probate records and some microfilmed early will registers and estate indexes.
