Anna filed for divorce from Rupert Murdoch in California, where she was entitled to half of everything Rupert had built since their marriage 31 years earlier. She sacrificed that right during the divorce negotiations to ensure that Rupert’s four existing children — and not any future heirs — would inherit his fortune after his death. Their eventual divorce agreement divided the controlling interest in the empire equally among the four: Prue, Liz, Lachlan and James. Rupert would have no say over who would run things after he was gone.
