Petitioners Southland Title Corporation, Land Title Insurance Company and Lawyers Title Insurance Corporation (Southland) seek a writ of mandate compelling the Los Angeles Superior Court to vacate an order which overruled Southlands demurrer to a cause of action for negligence and to enter a new and different order sustaining that demurrer. It was alleged that Southland had negligently prepared a preliminary report of title upon which a prospective buyer of residential real property had relied in deciding to purchase. The report failed to reflect a recorded flood control easement which affected the property.
