In any case when no parent, guardian, or custodian appears in a hearing with the juvenile or when the court finds it would be in the best interests of the juvenile, the court may appoint a guardian of the person for the juvenile. The guardian shall operate under the supervision of the court with or without bond and shall file only such reports as the court shall require. Unless the court orders otherwise, the guardian:
The authority of the guardian shall continue until the guardianship is terminated by court order, until the juvenile is emancipated pursuant to Subchapter IV of this Chapter, or until the juvenile reaches the age of majority.
