Britney "wants control of her life back," including the ability to make her own decisions about medical care, therapy, her finances and whether to get married and have a baby.
"In short, she wants to live her life as she chooses without the constraints of a conservator or court proceeding," the petition states.
USA TODAY has reached out to Jamie's and Britney's lawyers for comment.
Jamie's petition comes after he said in a filing on Aug. 12 that he planned to step down as the conservator of her finances, but offered no timetable. He gave up his control over her life decisions in 2019, keeping only his role overseeing her money.
He has repeatedly said there is no justification for his removal, and he has acted only in his daughter’s best interest.
