Section 4201 Of Article 3. Payment To Court Designated County Officer; Enforcement By District Attorney From California Family Law Code >> Division 9. >> Part 2. >> Chapter 2. >> Article 3.

. In any proceeding where a court makes or has made an order requiring the payment of child support to the person having custody of a child for whom support may be ordered, the court may do either or both of the following:
