Ordered that the order is reversed, on the law, with costs, and the joint motion for summary judgment dismissing the complaint is granted.
The plaintiff alleges, inter alia, that the defendants committed legal malpractice by failing to file a respondent's brief on his behalf on an appeal to this Court from a judgment of divorce in an underlying action entitled Campbell v Campbell, commenced in the Supreme Court, Dutchess County, under index No. 000849/98 ( see Campbell v Campbell, 286 AD2d 467).
The appellants made a prima facie showing of entitlement to judgment as a matter of law by demonstrating that the plaintiff would not have been successful on the appeal in the underlying action even if they had performed the tasks enumerated by the plaintiff in his complaint ( see Alvarez v Prospect Hosp., 68 NY2d 320; Cohen v Law Offs. of Leonard Robert Shapiro, 18 AD3d 219, 220; Spano v Love Balducci, 221 AD2d 992; Flinn v Aab, 167 AD2d 507). In opposition to that showing, the plaintiff failed to raise a triable issue of fact. Accordingly, the Supreme Court should have granted that branch of the appellants' motion which was for summary judgment dismissing the legal malpractice cause of action.
In addition, the Supreme Court should have granted summary judgment dismissing the plaintiffs remaining causes of action as duplicative of the legal malpractice cause of action ( see Town of N. Hempstead v Winston Strawn, LLP, 28 AD3d 746, 749; Ferdinand v Crecca Blair, 5 AD3d 538, 539).
