Actress Mischa Barton is suing her mum, claiming she stole money from her.

The 29-year-old has filed a lawsuit claiming her mother Nuala Barton skimmed money off her earnings while working as her manager for over 20 years.

In the lawsuit - reported by TMZ - British-born Mischa, who starred in Notting Hill and The Sixth Sense, claims her mother systematically withheld earnings and exploited her fame.

Mischa's complaint reads like a soap opera, stating: "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."

The actress is seeking unspecified damages. Her five-count complaint includes claims of breach of fiduciary duty, breach of oral contract and conversion.

Mischa, who made her name when she starred in The O.C. at the age of 17, claims her mother 'had absolutely no experience or training' in talent management when she took on her daughter's career.

She claims Nuala set up a scheme in which she exclusively controlled Mischa's finances and only 'doled out an 'allowance' to her at her sole discretion and on a sporadic basis'.

She alleges her mother induced her to buy a Beverly Hills home for $7.8 million in 2006 and 'represented to Barton that the lavish home would be a vehicle for which Barton could invest her growing income for acting services', but she structured the purchase to assign herself half-ownership of the property.

The complaint continues: "Nuala and Barton's father currently reside comfortably in the $7.8 million home. Barton is not welcome at the property."

Nuala allegedly lied about Mischa's compensation for acting in the horror film The Hoarder 'so that she could pocket the difference - on top of her hefty management fee - all without Barton's knowledge'.

She entered her daughter into endorsement contracts without telling her and launched enterprises like a Mischa Barton handbag line and Mischa Barton fashion boutique in London without compensating her daughter, claims the actress.

The complaint adds: "Nuala currently refuses to provide Barton with any of the funds she earned (and continues to earn in the form of residual payments) for her acting, modeling and endorsement services.

"These revelations of exploitation and fraud, coupled with ongoing instances of bullying and verbal abuse, eventually led to the breakdown of Barton and Nuala's personal and professional relationship."
