Ordered that the order is reversed, on the law, without costs or disbursements, and the matter is remitted to the Supreme Court, Queens County, for a hearing on the issue of whether the plaintiff was properly served with the defendant's motion, and a new determination of the plaintiffs motion to vacate thereafter.
The failure to provide proper service of a motion is a sufficient and complete excuse for a default on a motion and deprives the court of jurisdiction to entertain the motion ( see Bianco v LiGreci, 298 AD2d 482; Welch v State of New York, 261 AD2d 537; Golden v Golden, 128 AD2d 672; Adames v New York City Tr. Auth., 126 AD2d 462). The parties submitted conflicting evidence with respect to the issue of whether the plaintiff received the defendant's motion for summary judgment. Accordingly, a hearing on that issue is necessary ( see LPN Consulting Corp. v Hamm, 202 AD2d 479; Adames v New York City Tr. Auth., supra; Sport-O-Rama Health Fitness Ctr. v Centennial Leasing Corp., 100 AD2d 584).
