DECISION ORDER
ORDERED that the order is affirmed, with costs.
This medical malpractice action arises out of a knee replacement surgery performed upon the plaintiff Nathan Goldstein by the defendants Charles Bleifeld and Kevin Vesey at the defendant St. John's Episcopal Hospital in January 1992. In October 1992, the plaintiffs filed for bankruptcy but failed to list any medical malpractice claim as an asset in their bankruptcy petition. The plaintiffs were discharged in bankruptcy in 1993 and in 1994 they commenced the instant action. Four years later, the defendants separately moved for leave to amend their answers to assert as an affirmative defense the plaintiffs' lack of capacity to sue, and for summary judgment dismissing the complaint insofar as asserted against them. The Supreme Court granted the motions.
The Supreme Court providently exercised its discretion in granting the defendants leave to amend their answers. Leave to amend a pleading should be freely given (see, CPLR 3025[b]) provided the amendment is not defective on its face and does not prejudice or surprise the opposing party (see, Smith v. Peterson Trust, 254 A.D.2d 479 ; see also, Romeo v. Arrigo, 254 A.D.2d 270 ). Here, the defendants moved promptly for leave to amend their answers upon learning of the prior bankruptcy proceeding, and the plaintiffs were unable to show any surprise or prejudice (see, Quiros v. Polow, 135 A.D.2d 697 ). Having failed to list the medical malpractice cause of action in the schedule of assets filed with the bankruptcy court, the plaintiffs lacked the capacity to sue (see, Pinto v. Ancona, 262 A.D.2d 472 [2d Dept., June 14, 1999]; Bromley v. Fleet Bank, 240 A.D.2d 611 ; Reynolds v. Blue Cross of Northeastern N.Y., 210 A.D.2d 619 ; Quiros v. Polow, supra). Accordingly, the defendants were entitled to summary judgment.
