Every officer or employee, by virtue of his office or position, or of any law, entrusted or charged with the receipt, custody or expenditure of money or funds of the local unit, and any other officer or employee required so to do by the governing body thereof, shall, before entering upon the duties of his office or position, execute and deliver his bond, or shall be otherwise bonded to the local unit in its corporate name, conditioned for the true and faithful performance of his duties. All bonds shall be in such form, for such sum and with such surety as the governing body of the local unit shall, by resolution, direct. The governing body may, in any instance, require corporate surety. All such bonds, in the case of a county, shall be filed with the clerk of the board of chosen freeholders, except that the bond of the clerk, if there be any, shall be filed with the county treasurer. In the case of municipalities, all bonds shall be filed with the municipal clerk, except the bond of the clerk, which shall be filed with the treasurer. The bonds shall be preserved for and be the property of the local unit.
