Order unanimously reversed on the law with costs and motion denied. Memorandum: Supreme Court erred in granting defendant's motion to dismiss plaintiff's complaint. Defendant failed to show, by proof of an office practice or procedure followed in the regular course of business, that the policy of insurance issued to plaintiff was duly addressed and mailed (see, Nassau Ins. Co. v. Murray, 46 N.Y.2d 828). The mere assertion by one of defendant's agents that the policy "was sent", supported by the agent's reference to an ambiguous notation on a microfiche record purporting to document the mailing, is insufficient to give rise to the presumption that attaches to notices duly addressed and mailed (see, Friedman v. Allcity Ins. Co., 118 A.D.2d 517; cf., Aetna Cas. Sur. Co. v. Preisigke, 139 A.D.2d 900).
