Insurance Law § 3420(d) requires an insurer to give the insured timely notice of disclaimer as soon as reasonably possible and applies to a "liability policy delivered or issued for delivery in this state" (emphasis added). We reject plaintiff's claim that the timely disclaimer provision is inapplicable in this case merely because the policy in question was issued out of State and listed the address of the insured's corporate headquarters out of State. The policy expressly covers insureds and risks located in New York and must therefore be deemed issued for delivery in New York (see, Am. Ref-Fuel Co. of Hempstead v. Employers Ins. Co. of Wausau, 265 A.D.2d 49, 53).
It is settled that failure by the insurer to give written notice of disclaimer based on an exclusion or failure to comply with a policy condition as soon as is reasonably possible renders the disclaimer ineffective (Hartford Ins. Co. v. County of Nassau, 46 N.Y.2d 1028). Here, plaintiff's 17-month delay in disclaiming coverage was clearly unreasonable and therefore the disclaimer was ineffective regardless of whether defendants gave timely notice of the claim (see, Wasserheit v. New York Cent. Mut. Fire Ins. Co., 271 A.D.2d 439; Matter of State Farm Ins. Co. v. Brosnan, 220 A.D.2d 599). Plaintiff's additional grounds for disclaiming coverage are based on exclusionary clauses without which there would be coverage and therefore compliance with Insurance Law § 3420(d) is required (see, Matter of Worcester Ins. Co. v. Bettenhauser, 95 N.Y.2d 185, 188-189; Handelsman v. Sea Ins. Co. Ltd., 85 N.Y.2d 96, 99).
