(a) If a child appears before the juvenile court without a parent or guardian, the court shall appoint a guardian ad litem to protect the interests of the child. The juvenile court need not appoint a guardian ad litem if a parent or guardian appears with the child.(b) In any case in which it appears to the juvenile court that the child’s parent or guardian is incapable or unwilling to make decisions in the best interest of the child with respect to proceedings under this title, the court may appoint a guardian ad litem to protect the interests of the child in the proceedings.(c) An attorney for a child may also be his guardian ad litem. A law-enforcement officer, probation officer, or other employee of the juvenile court may not be appointed guardian ad litem.
