Jamie Spears is asking a Los Angeles Superior Court judge to add Jason Trawick as a co-conservator over his pop star daughter, according to papers filed on Friday.
Trawick will only have shared legal control over Spears’s general well being – not her finances, a source tells PEOPLE. 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 previously told PEOPLE.
