N.Y. County Law § 402: Oath of office

§ 402. Oath of office. Every officer paid his compensation from county

funds shall take and file an official oath in the manner prescribed in

section ten of the public officers law. The refusal or neglect to take

and file such oath within the time prescribed by section thirty of the

public officers law, except in the cases of the sheriff, county clerk

and district attorney, shall be deemed a refusal to serve and the office

may be filled as in the case of a vacancy. Until the sheriff, county

clerk or district attorney shall take and file the required oath, he

shall not perform any duties of the office, nor be entitled to any

compensation.
