§ 211. Pleadings, proof and motions. A matrimonial action shall be

commenced by the filing of a summons with the notice designated in

section two hundred thirty-two of this chapter, or a summons and

verified complaint as provided in section three hundred four of the

civil practice law and rules. A final judgment shall be entered by

default for want of appearance or pleading, or by consent, only upon

competent oral proof or upon written proof that may be considered on a

motion for summary judgment. Where a complaint or counterclaim in an

action for divorce or separation charges adultery, the answer or reply

thereto may be made without verifying it, except that an answer

containing a counterclaim must be verified as to that counterclaim. All

other pleadings in a matrimonial action shall be verified.
