N.M. Admin. Code § 8.50.124.12
In interstate cases, the Title IV-D agency works closely with the child support agency in another jurisdiction. It is important that the Title IV-D agency be made aware of all communication in interstate cases in order to stay fully aware of the status of the cases. Accordingly, a party to an interstate action must not communicate directly with a child support agency in another jurisdiction. If an individual communicates directly with a child support agency in another jurisdiction without utilizing the Title IV-D agency, this conduct may be deemed to be "non-cooperation" by the Title IV-D agency and may subject the party to sanction and case closure, as appropriate. Parties in interstate cases must also follow the cooperation guidelines set forth in 8.50.105.12 NMAC or be deemed to be "non-cooperative" and be subjected to sanction and case closure, as appropriate.
