“Jamie’s thrilled,” his attorney Geraldine Wyle told reporters following the hearing, referring to Spears’s father. “It’s all in the family.”
Wyle also clarified that the request to add Trawick came at Britney’s request, not Jamie’s.
Conservators typically have legal authority over a person’s general well-being, which includes decisions about food, clothing and medical care.
A source close to the singer previously told PEOPLE that Britney enjoys plenty of personal freedom and that the conservatorship is mostly in name only.
Trawick will not have any legal control over Britney’s multimillion-dollar fortune, which is overseen by her father and another attorney.
The conservatorship will be lifted only after a judge is convinced, on the advice of the singer’s doctors, that she’s healthy enough to manage her own affairs.
