The Lundy court stated that the insured must have either actual notice of the insurer's intent to rescind or that "`such intention has been so expressed as to give notice to the ordinary [person] in the exercise of ordinary care.'" Lundy, 100 S.E.2d at 546-47 (quoting Grant Lumber Co. v. N. River Ins. Co., D.C., 253 F. 83, 88 (D.Idaho 1918)). The Lundy court further held that a court may consider whether, as a matter of law, an insured failed to act as a person of reasonable prudence in cashing a premium refund check tendered by an insurer.
