After a petition has been filed pursuant to

Section 311, and until the time that the petition is dismissed or dependency is terminated, no other division of any superior court may hear proceedings pursuant to

Part 2 (commencing with

Section 3020) of Division of the Family Code regarding the custody of the child or proceedings under

Part 2 (commencing with

Section 1500) of Division of the Probate Code, except as otherwise authorized in this code, regarding the establishment of a guardianship for the child. While the child is under the jurisdiction of the juvenile court all issues regarding his or her custody shall be heard by the juvenile court. In deciding issues between the parents or between a parent and a guardian regarding custody of a child who has been adjudicated a dependent of the juvenile court, the juvenile court may review any records that would be available to the domestic relations division of a superior court hearing that matter. The juvenile court, on its own motion, may issue an order as provided for in

Section 213.5, or as described in

Section of the Family Code. The Judicial Council shall adopt forms for these restraining orders. These form orders shall not be confidential and shall be enforceable in the same manner as any other order issued pursuant to Division 10 (commencing with

Section 6200) of the Family Code. This

section shall not be construed to divest the domestic relations division of a superior court from hearing any issues regarding the custody of a child when that child is no longer a dependent of the juvenile court.
