Ordered that the order is affirmed insofar as appealed from, with costs.
Although broad financial disclosure is necessary and required in a matrimonial action (see, Domestic Relations Law § 236 [B] [4]; De La Roche v. De La Roche, 209 A.D.2d 157, 158; Gellman v. Gellman, 160 A.D.2d 265, 267), the trial court is also vested with "broad discretion to supervise disclosure to prevent unreasonable annoyance, expense, embarrassment, disadvantage or other prejudice" (Annexstein v. Annexstein, 202 A.D.2d 1060, 1061; see, Hirschfeld v. Hirschfeld, 69 N.Y.2d 842, 844). Under the circumstances of the instant case, we conclude that the court properly exercised its discretion in denying the plaintiff's present motion for leave to depose the defendant, as the record firmly supports the court's conclusion that the plaintiff has used discovery as "a tool for harassment [and] financial waste".
