The insurance issued by a title company for a parcel of real estate. Title insurance protects a property owner against later discovery that the title to the property is imperfect or defective. The purpose of title insurance is to deal with the imperfection of land records. For example, a buyer of a parcel of real estate discovers later that another person or party has an easement, a right to use a portion of the property such as to cross onto and through the property at will to reach the other side.
