Plaintiff’s have 120 days from the time they file the complaint with the County Clerk to serve the Defendant. When the Plaintiff fails to serve, the Defendant may move to dismiss the complaint under CPLR 306-b. “Although Plaintiff’s failed to properly effect service of process, his [Plaintiff’s] cross motion for an order extending his time to serve the summons and complaint should have been granted in the interest of justice. (CPLR 306-b.) Interest of justice requires a careful judicial analysis of the factual setting of the case and a balance of the competing interests of the parties.” (Leader v. Maroney, Pnzini & Spencer, 97 N.Y.2d 95, 105 ).
