Cal. Rules of Court, rule 5.620

(a) Exclusive jurisdiction (§ 304)

Once a petition has been filed alleging that a child is described by section 300, and until the petition is dismissed or dependency is terminated, the juvenile court has exclusive jurisdiction to hear proceedings relating to the custody of the child and visitation with the child and establishing a legal guardianship for the child.

(b) Restraining orders (§ 213.5)

After a petition has been filed under section 300, and until the petition is dismissed or dependency is terminated, the court may issue restraining orders as provided in rule 5.630. A temporary restraining order must be prepared on Notice of Court Hearing and Temporary Restraining Order-Juvenile (form JV-250). An order after hearing must be prepared on Juvenile Restraining Order After Hearing (form JV-255).

(c) Custody and visitation (§ 361.2)

If the court sustains a petition, finds that the child is described by section 300, and removes physical custody from a parent or guardian, it may order the child placed in the custody of a previously noncustodial parent as described in rule 5.695(a)(7)(A) or (B).

(1) This order may be entered at the dispositional hearing, at any subsequent review hearing under rule 5.708(k), or on granting a request under section 388 for custody and visitation orders.

(2) If the court orders legal and physical custody to the previously noncustodial parent and terminates dependency jurisdiction under rule 5.695(a)(7)(A), the court must proceed under rule 5.700.

(3) If the court orders custody to the noncustodial parent subject to the continuing supervision of the court, the court may order services provided to either parent or to both parents under section 361.2(b)(3). If the court orders the provision of services, it must review its custody determination at each subsequent hearing held under section 366 and rule 5.708.

(d) Appointment of a legal guardian of the person (§§ 360, 366.26)

If the court finds that the child is described by section 300, it may appoint a legal guardian at the disposition hearing, as described in section 360(a) and rule 5.695(a), or at the hearing under section 366.26, as described in that section and rule 5.735. The juvenile court maintains jurisdiction over the guardianship, and a petition to terminate or modify that guardianship must be heard in juvenile court under rule 5.740(c).

(e) Termination or modification of previously established probate guardianships (§ 728)

At any time after the filing of a petition under section 300 and until the petition is dismissed or dependency is terminated, the court may terminate or modify a guardianship of the person previously established under the Probate Code.

The social worker may recommend to the court in a report accompanying an initial or supplemental petition that an existing probate guardianship be modified or terminated. The probate guardian or the probate guardian or the child’s attorney may also file a motion to modify or terminate an existing probate guardianship.

(1) The hearing on the petition or motion may be held simultaneously with any regularly scheduled hearing regarding the child. The notice requirements in section 294 apply.

(2) If the court terminates or modifies a previously established probate guardianship, the court must provide notice of the order to the probate court that made the original appointment. The clerk of the probate court must file the notice in the probate file and send a copy of the notice to all parties of record identified in that file.
