Britney Spears' father can retain temporary control of the singer's assets and affairs until March, a Los Angeles court has ruled.
Spears' parents are concerned about her mental health
James Spears was granted "temporary conservatorship" over his 26-year-old daughter's life two weeks ago when she was admitted to a psychiatric ward.
In addition, Spears' brother Bryan, 30, has been named co-trustee, along with a legal firm.
A court creates a conservatorship when a person cannot care for themselves.
James Spears' lawyer Jeryll Cohen also told the hearing investigators had been struggling to find the singer's sometime manager, Sam Lutfi, to serve a restraining order against him.
Last week a court banned Mr Lutfi from going near the singer, after her mother claimed he had taken virtually over the star's life and had even been drugging her.
"We have made great effort to have Mr Lutfi served," said Mr Cohen.
"We staked out his residence at the hospital. We did many things we do not want to discuss right now. We have information he is intentionally avoiding service," he added.
The restraining order means Mr Lutfi must not contact Spears in any way and must stay away from the homes of her parents and her siblings.
Court documents have also revealed Mr Spears has been granted permission to sack his daughter's business manager, Howard Grossman.
