A defendant may move to vacate the default on the ground of a lack of notice of the action, pursuant to CPLR 5015(a)(1). Pursuant to CPLR 317, if service was by means other than personal delivery, the defendant may be permitted to defend the action upon the court's finding that the defendant did not receive notice of the summons in time to defend and has a potentially meritorious defense. However, a conclusory and unsubstantiated denial of receipt of the summons and complaint is insufficient to establish lack of notice.
