(a)
(1) The State agency must refer all appropriate individuals in the family of a child, for whom paternity has not been established or for whom a child support order needs to be established, modified or enforced, to the child support enforcement agency (i.e., the IV-D agency).
(2) Referred individuals must cooperate in establishing paternity and in establishing, modifying, or enforcing a support order with respect to the child.
(b) If the IV-D agency determines that an individual is not cooperating, and the individual does not qualify for a good cause or other exception established by the State agency responsible for making good cause determinations in accordance with section 454(29) of the Act or for a good cause domestic violence waiver granted in accordance with § 260.52 of this chapter, then the IV-D agency must notify the IV-A agency promptly.
(c) The IV-A agency must then take appropriate action by:
(1) Deducting from the assistance that would otherwise be provided to the family of the individual an amount equal to not less than 25 percent of the amount of such assistance; or
(2) Denying the family any assistance under the program.
