Cal. Welfare and Institutions Code § 11485

If, to the knowledge of the court, aid has been applied for or granted to a child of parents who are engaged in a divorce or separate maintenance action which is pending, or if the court at any stage of the litigation believes that within the near future there is a likelihood that aid will be applied for on behalf of the child, the court shall direct the clerk to notify the local child support agency and the county department of the pending action. In any case in which aid has been applied for on behalf of the child, and the county department has knowledge that an action for divorce or separate maintenance has been filed, it shall be the duty of the county director to notify the court that aid is being paid or has been applied for, and to furnish to it such information as is available to the county department as to the financial resources of the parents which might be applied to child support. The enforcement remedies provided the local child support agency under this article shall not preclude the use of any other remedy which he has under the law to enforce this article.
