Lawyers for troubled singer Britney Spears are heading to court to fight an order which has given her father control of her estate, according to U.S. reports. The Toxic star is currently being held at a Los Angeles hospital for psychiatric treatment and on Friday (01Feb08) a judge granted her father Jamie, and lawyer Andrew Wallet, temporary conservatorship - meaning they are in complete charge of Spears' medical, financial and legal affairs. Jamie even has the right to restrict people visiting the 26-year-old. But a further court hearing is scheduled for Monday (04Feb08) and according reports from U.S. websites People.com and TMZ.com, Spears' attorneys are expected to object to the amount of control which has been handed to her father. Meanwhile, a planned hearing in the singer's ongoing custody battle for her two sons is expected to go ahead without her on Monday (04Feb08). Spears was admitted to UCLA Medical Center on Thursday morning (31Jan08) and placed on a psychiatric hold which could last anywhere from 72 hours up to two weeks.
