The "OC" star filed the complaint in the Los Angeles Superior Court, where she has accused Nuala of being greedy, said the Hollywood Reporter.
"This action arises from the tragic tale of a greedy stage mother posing as a talent manager who, instead of acting in the best interest of her daughter/client, schemed to defraud her unsuspecting victim," read her complaint.
Barton is seeking unspecified damages, triple the amount the court finds her mother to have withheld. Her five-count complaint includes claims of breach of fiduciary duty, breach of oral contract and conversion.
Barton also alleged that her mother induced her to buy a USD 708 million home in Beverly Hills where the actress is no longer welcome.
