A number of years ago, a couple purchased a three-story house in Woodside, Queens, that contained three separate dwelling units, each with its own kitchen, bathroom and separate entrance. Thereafter, the couple applied for and obtained a fire insurance policy from Otsego Mutual Fire Insurance Co., indicating on their application that the house was a two-family dwelling. After the house was damaged by fire, Otsego rescinded its policy on the ground that the couple had made a material misrepresentation of fact by stating on their insurance application that the house was a two-family dwelling.
