Britney Spears' dad Jamie has officially been handed legal and permanent conservatorship over the singer's estate almost a year after he was first put in charge of his daughter's affairs.

Jamie Spears was made a co-conservator of his daughter's legal, financial and personal dealings in February following a public breakdown in which the singer was entered into hospital to undergo a mental evaluation. The elder Spears and lawyer Andrew Wallet stayed on as co-conservators throughout the remainder of the year, overseeing the Toxic superstar's every move, including plans for her forthcoming Circus tour.

In October, a Los Angeles judge made Jamie Spears' control of his daughter's estate and wealth permanent, and in December he was provided with a pay rise from $10,000 to $16,000 a month. And on Monday, court papers were filed in L.A. Superior Court to make the conservatorship legally official, stating that the star "is substantially unable to manage … her financial resources or to resist fraud or undue influence."

According to Access Hollywood, the documents also state that Jamie Spears will have full power, even over who visits and befriends his daughter, saying that he has "the power to restrict and limit visitors by any means."
