    Janet Glasser, Appellant, v City of New York, Respondent, et al., Defendants.
    [697 NYS2d 167]
   —In a negligence action to recover damages for personal injuries, the plaintiff appeals from so much of an order of the Supreme Court, Queens County (Weiss, J.), dated October 8, 1998, as denied her motion to strike the answer of the defendant City of New York for willful noncompliance with a notice to admit.

Ordered that the order is affirmed insofar as appealed from, with costs.

The Supreme Court properly determined that the plaintiffs notice to admit sought an admission which went to the heart of the matter at issue, i.e., constructive notice of a defect, and was thus improper (see, DeSilva v Rosenberg, 236 AD2d 508; Ashkenazi v City of New York, 239 AD2d 186, 187; National Union Fire Ins. Co. v Allen, 232 AD2d 80, 85).

In any event, the City of New York properly responded to the notice to admit by denying receipt of the letter at issue, and by providing the reasons for its denial. Should the plaintiff prove at trial the City’s receipt of the letter, she can then seek the appropriate relief at that time (see, CPLR 3123 [c]). Contrary to the plaintiffs claims, CPLR 3123 is self-executing, and the penalties embodied in CPLR 3126 do not apply (see, Matter of T. / P. Children, 165 Misc 2d 333, 334; Spawton v Strates Shows, 75 Misc 2d 813, 815). Santucci, J. P., Altman, Friedmann and H. Miller, JJ., concur.
