Order affirmed, with costs.
A plaintiff is entitled to use the so-called "nail and mail" provisions of CPLR 308 (4) only if personal service cannot be effected under subdivisions (1) and (2) thereof by the use of "due diligence". Due diligence was not established here where the process server, in an affidavit in opposition to appellant's motion and in support of the cross motion, stated only that he was unable to serve defendant Zupnick "in hand" at his place of business on three occasions, but did not explain why he was unable to leave the summons and complaint with a person of suitable age and discretion on any of those occasions, or why he never attempted to serve Zupnick at his home. Under these circumstances, we conclude that Special Term properly determined that due diligence had not been established, and that jurisdiction over Zupnick had not been obtained (see, e.g., Barnes v City of New York, 70 A.D.2d 580, affd 51 N.Y.2d 906; Reed v Domenech, 90 A.D.2d 844). Mangano, J.P., Bracken, Weinstein, Lawrence and Kooper, JJ., concur.
