Existing law establishes the jurisdiction of the juvenile court, which may adjudge a child to be a dependent of the court under certain circumstances, including when the child suffered, or there is a substantial risk that the child will suffer, serious physical harm, or a parent fails to provide the child with adequate food, clothing, shelter, or medical treatment. Existing law establishes the grounds for removal of a dependent child from the custody of their parents or guardian, and establishes procedures to determine placement of a child. Existing law requires, when a child has been adjudged a dependent of the court, the court to hold a dispositional hearing to determine the disposition to be made of the child. Under existing law, if the child is removed from the physical custody of their parents, preferential consideration to be given to a request by a relative of the child for placement of the child with the relative. Existing law prescribes factors for the county social worker and court to consider in determining placement, and requires the court to state on the record the reasons placement was denied if the court does not place the child with a relative who has been considered for placement.
