Before entering upon his duties every officer shall file with the City Clerk the constitutional oath of office, and if required by this Charter or by resolution of the Council an undertaking in accordance with the provisions of the public officers laws in the amount required by such resolution or by law, which undertaking shall be approved by the City Manager (except as to his own, which shall be approved by the Mayor), as to the sufficiency of the surety or sureties, and by the Corporation Counsel as to its form and validity. The City Manager (except in his own case, when the Mayor shall act in his place) shall examine the sufficiency of the proposed sureties of any officer or person from whom an official undertaking is required, and may require such sureties to be examined under oath as to their qualifications. The justification of such surety shall be reduced to writing, subscribed by him, certified by the officer administering the oath and annexed to and filed with the undertaking. In case any officer fails to file the oath of office, or an undertaking, if required, on or before the beginning of his term of office, if it is an elective office or, if it is an appointive office, within 10 days after his appointment, his office shall be deemed vacant and must be filled as herein provided.
The expense of procuring official undertakings by officers, whenever the same are required to be given, shall be paid by the city upon presentation of claims for the same and the auditing and approval thereof in the manner provided for claims against the city.
