A San Francisco house worth about $4.4 million changed hands through 8 disputed deeds in little over a year; the city has now sued to cancel them all and restore the property record

• San Francisco City Attorney David Chiu filed the case in state court, seeking to clear the city's property records and restore the title to its rightful owner.
• The legal action follows more than a year of disputed quitclaim deeds, questionable ownership transfers and claims by people who allegedly had no legal right to the house.
