The richest Australian, Gina Rinehart, is being sued by her daughter in a Sydney court, according to the Sydney Morning Herald.
The details of the lawsuit filed by Hope Rinehart Welker against her mother are still unknown, and only mentioned briefly in NSW Supreme Court today.
Rinehart Walker's barrister, Alan Sullivan, said the reasons for the application involved "the impact on commercial negotiations."
Gian Rinehart earned her $11 billion fortune through mining, and is on track to become the richest person in the world, according to a report from Citigroup. Unless her daughter takes it all first, that is.
