Deputies.
1.
County treasurers may appoint one or more deputies and may take from them bond with sureties. A deputy must be at least 18 years of age. Every county treasurer and the county treasurer’s sureties are liable for every official act of his or her deputies.2.
Any county treasurer may authorize his or her deputy or deputies to transact any official business pertaining to the office of county treasurer in the same manner as the county treasurer. The appointment of a deputy must not be construed to confer upon that deputy policymaking authority for the office of the county treasurer or the county by which the deputy is employed.3.
All appointments of deputies under the provisions of this section must be in writing and must, together with the oath of office of the deputies, be recorded in the office of the recorder of the county within which the county treasurer legally holds and exercises his or her office. Revocations of such appointments must also be recorded as provided in this section. From the time of the recording of the appointments or revocations therein, persons shall be deemed to have notice of the appointments or revocations.
