Zsa Zsa Gabor's daughter is petitioning for the ailing actress to be placed under a court-ordered conservatorship.
Constance Francesca Hilton has filed documents at Los Angeles Superior Court requesting the independent management of her mother's medical and financial affairs.
She is asking officials to decide whether Gabor is receiving the best care she can afford and whether she is being isolated or allowed to be with her friends and family.
Hilton is also seeking a ruling on whether her mother's funds are being managed in her best interests.
Gabor is currently being cared for by her husband, Prince Frederic von Anhalt. She has been in and out of hospital since breaking her hip in a fall in July 2010.
A spokesman for Hilton's legal team says, "This is not a proceeding about Ms. Hilton or Mr. Frederic von Anhalt... it is a proceeding where Zsa Zsa's best interests are in the forefront. The court will listen to the perspective of both Ms. Hilton and Mr. von Anhalt, but Zsa Zsa's best interests will control...
"Zsa Zsa Gabor's daughter had been waiting patiently for over a year to receive medical evaluations about her mother as well as financial documents from Mr. von Anhalt showing that he is capable of caring for her mother in a healthy and financially secure environment. He has refused."
