Britney Spears' father petitions court

Britney Spears' father Jamie is reportedly asking the court to add the singer's fianc , Jason Trawick, as a co-conservator over her.

Trawick will only have shared legal control over Spears' general well being - not her finances, People magazine quoted a source as saying.

In general, a conservator can make decisions over a person's food, clothing and medical care. But Spears has plenty of personal freedom and the conservatorship is just a formality, another source had previously said.

"This is a very unusual situation, because generally you don't see conservatees get married," said Jeffrey S Cohen, an LA probate attorney not involved with the case.

"This could be a sign that the couple's wedding is around the corner.

"This is probably a compromise between Britney, her father and Trawick to get the marriage off on the right foot. Obviously, her future husband needs to have a say in her well being," he added.

Jamie Spears has held legal control over his daughter and her multimillion-dollar fortune since February 2008 after she suffered a psychological breakdown.

The conservatorship will be lifted only after a judge is convinced, on the advice of the pop star's doctors, that she's healthy enough to manage her own affairs.
