When the division of child support (DCS) opens a new IV-D case, DCS must:

(1) Determine whether or not there is already an existing child support order or orders in effect in the case. DCS uses the state and federal case registries, state records, information provided by the recipient of services, and other relevant information;

(2) Determine which jurisdiction may make a determination of the controlling order and reconciliation of arrearages if there are multiple orders; and

(3) Determine whether the noncustodial parent (NCP) is in another jurisdiction and whether it is appropriate to use its one-state remedies to establish paternity and establish, modify, and enforce a support order, including medical support and income withholding.
