The record evidence demonstrates that defendant's possession of the medical records constituted actual notice of the pertinent facts and that defendant would not be substantially prejudiced by plaintiffs' delay in serving the notice of claim ( see Bayo v Burnside Mews Assoc., 45 AD3d 495; De La Cruz v New York City Health Hosps. Corp., 13 AD3d 130). Plaintiff's submitted affirmations from a physician establishing that the medical records, on their face, evince that defendant failed to provide proper care to plaintiff's ( compare Williams v Nassau County Med. Ctr., 6 NY3d 531, 537), and defendant's argument that the delay would prejudice it in defending the action because of an inability to reconstruct events and conversations is unconvincing ( see Matter of Banegas-Nobles v New York City Health Hosps. Corp., 184 AD2d 379, 380).
