Ordered that the order is affirmed, with costs.
In opposition to the defendant insurer's prima facie showing of entitlement to judgment as a matter of law based upon the plaintiffs eight-month delay in reporting the underlying occurrence to it, the plaintiff raised a triable issue of fact as to whether the delay was reasonable, based upon a good faith belief in its nonliability. Under these circumstances, the Supreme Court properly denied the defendant's motion for summary judgment ( see St. James Mech., Inc. v Royal Sunalliance, 44 AD3d 1030, 1031-1032; Genova v Regal Mar. Indus., 309 AD2d 733).
