Attorney Tamar Arminak on Thursday confirmed the 27-year-old actress's release after several months of treatment.
Bynes has been in treatment since July, when she was placed on a psychiatric hold after starting a fire in a driveway in her hometown of Thousand Oaks, Calif. Her mother, Lynn Bynes, was granted a temporary conservatorship over the actress, but the case was dismissed because Amanda Bynes' care was being overseen by a mental health court.
Arminak wrote in a statement to People magazine that Amanda Bynes' treatment will continue and she is considering returning to school to study fashion design.
Bynes' release was first reported by celebrity website RadarOnline.com.
The actress starred in the Nickelodeon show "All That" and her own variety series.
