Amer Haddadin says he'll proceed with an eviction if Suleman and her lawyer Jeff Czech don't pay him the balance on the house by the end of the year.
Haddadin says Czech and Suleman became joint owners of the house, after her father bought the home and transferred the deed. He suspects they have the money to pay him.
Reached by phone Sunday, Czech said he hadn't heard anything about the proceedings and had no immediate comment.
Suleman and her 14 children have lived in the house since her octuplets came home from the hospital nearly two years ago.
