Memorandum: Supreme Court abused its discretion in granting petitioner's application for leave to serve a late notice of claim pursuant to General Municipal Law § 50-e (5) ( see generally Palumbo v City of Buffalo, 1 AD3d 1032). In support of her application, petitioner failed to demonstrate any nexus between the infancy of her daughter, who allegedly was diagnosed with lead poisoning as a result of her exposure to lead paint at premises owned by respondent, and the 15-year delay in seeking leave to serve the late notice of claim. "A delay of service caused by infancy would make a more compelling argument to justify an extension. Conversely, the lack of a causative nexus may make the delay less excusable, but not fatally deficient" ( Williams v Nassau County Med. Ctr., 6 NY3d 531, 538). Nevertheless, we conclude that the application should have been denied based on petitioner's failure to offer a reasonable excuse or, indeed, any excuse for the 15-year delay in seeking leave to serve a late notice of claim ( see Matter of Nairne v New York City Health Hosps. Corp., 303 AD2d 409, 410; Matter of Ertel v Town of Amherst, 267 AD2d 1024), petitioner's failure to establish that respondent had "`actual knowledge of the essential facts of the claim within the meaning of General Municipal Law § 50-e (5)'" ( Santana v Western Regional Off-Track Betting Corp., 2 AD3d 1304, 1305 [2003], lv denied 2 OT3d 704 [2004]), and petitioner's failure to "rebut . . . respondent's assertion that the extensive delay in this case substantially prejudiced its ability to investigate and defend against the claim" ( Nairne, 303 AD2d at 410; see Matter of Landa v City of New York, 252 AD2d 525, 526).
