The Kardashian sisters are taking stepmother Ellen Pearson to court, outraged that she sold their late father's diaries and photos to gossip magazines.
Kim, Khloe and Kourtney Kardashian are thought to have filed a lawsuit against Pearson, criticising her for carrying out a "despicable and unlawful scheme to hold in secret and convert, and now exploit... private, personal and copyright protected [material]".
Gossip Cop reports that their late father Robert Kardashian's will gave them the rights to the "bulk of his personal tangible and intangible property", which covers his books, works on paper, "rights in literary... properties, rights in works of art", publishing rights, and rights to a "deceased personality's name, voice, signature, photograph or likeness".

The sisters also accuse Ellen of willfully hiding the posessions, which she leaked to In Touch and Life & Style magazines for profit. She allegedly failed to declare them when she went bankrupt in 2010, despite being aware of their monetary value.
They are seeking at least half a million dollars in damages, plus more in "profits, statutory damages, punitive and exemplary damages".
Their attorney Marty Singer says: "The Kardashians and Kris Jenner have filed a suit against Ellen Pearson for taking personal property belonging to them by virtue of Robert Kardashian’s will and by virtue of copyright protection.
"The filing should serve as notice that they will vigorously defend their rights when forced to do so."
