¶1— Order, Supreme Court, New York County (Stanley L. Sklar, J.), entered on or about December 4, 1990, which, inter alia, denied defendant Dr. Mitchell’s motion for summary judgment, on the ground that plaintiffs’ claim against her was barred by the statute of limitations, and granted plaintiffs’ motion to add defendant Michael Truppin, P. C., as a party, unanimously affirmed, with costs.
¶2We find plaintiffs’ service upon Dr. Mitchell, pursuant to CPLR 203 (b) (5), upon the County Clerk in the county in which she last resided or was last employed proper and sufficient to toll the statute of limitations for an additional 60 days, within which time personal service upon Dr. Mitchell was complete. It is of no consequence that plaintiffs may have known Dr. Mitchell’s address outside of the State prior to delivery of the summons to the County Clerk. (Rossi v Oristian, 50 AD2d 44, 48-49.) Accordingly, the action was timely brought against Dr. Mitchell.
¶3We further find that IAS committed no error in adding Michael Truppin, P. C., as a party defendant since all of the prerequisites for leave to file the proposed amended complaint were met.
