Idaho Code § 54-1228: Administering and certification of oaths — Authority of professional land surveyors.

Every professional land surveyor is authorized to administer and certify oaths, when it becomes necessary to take testimony to identify or establish old or obliterated corners, or to perpetuate a corner that is in a perishable condition, or whenever the importance of the land survey makes it desirable. A record of such oaths shall be kept as part of the field notes of the land survey.
