Ordered that the orders are affirmed insofar as appealed from, with one bill of costs.
To successfully oppose a motion for leave to enter a default judgment based on the failure to timely serve an answer, a defendant must demonstrate a reasonable excuse for the delay and the existence of a potentially meritorious defense ( see May v Hartsdale Manor Owners Corp., 73 AD3d 713; Kouzios v Dery, 57 AD3d 949; Giovanelli v Rivera, 23 AD3d 616; Mjahdi v Maguire, 21 AD3d 1067, 1068; Thompson v Steuben Realty Corp., 18 AD3d 864, 865; Dinstber v Fludd, 2 AD3d 670, 671). Here, the appellants failed to demonstrate a reasonable excuse. Since the appellants failed to demonstrate a reasonable excuse for their default, it is unnecessary to determine whether they demonstrated the existence of a potentially meritorious defense ( see Levi v Levi, 46 AD3d 519, 520; Mjahdi v Maguire, 21 AD3d at 1068). Accordingly, the Supreme Court properly granted the plaintiffs motion, in effect, for leave to enter a default judgment against the appellants and for an order of reference, and properly denied the appellants' motion, in effect, to vacate the default, and to dismiss the complaint, or for leave to serve a late answer and third-party complaint.
The appellants' remaining contentions are without merit.
