Existing law establishes the jurisdiction of the juvenile court, which may adjudge children to be dependents 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 the child’s parents or guardian, and requires the court to order the social worker to provide designated child welfare services, including family reunification services, as prescribed. Existing law provides that reunification services do not need to be provided to a parent or guardian when the court finds, by clear and convincing evidence, that the parent or guardian of the child has been convicted of a violent felony, as defined.
