It was not immediately known who brought Thursday's action, known as an ex-parte motion.
Two lawyers for Spears' father James - who has been named as her conservator - were in court along with Spears' court-appointed attorney and an attorney for the conservatorship. A conservatorship is created when a court determines a person can no longer care for his or her own affairs.
The hearing came a day after Spears was suddenly released from a psychiatric hospital, drawing objections from her parents.
