(1) When the division of child support (DCS) is setting a support obligation for only one parent, DCS follows the steps set out in this section.

(2) The noncustodial parent (NCP) for whom DCS is setting support is called the party NCP, because that parent is a party to the administrative action.

(3) The parent for whom DCS is not setting support is called the nonparty NCP, because that parent is not a party to the administrative action.

(4) DCS completes a Washington state child support schedule (WSCSS) worksheet using income information for both the party NCP and for the nonparty NCP, instead of setting support based solely on the income of the party NCP.

(5) DCS uses the best available information regarding the income of both the party NCP and the nonparty NCP, as provided in WAC 388-14A-3205.

(6) DCS does not include the income of a nonparty NCP in the worksheets if:

(a) Paternity has not been established for the child;

(b) The nonparty NCP's parental rights have been terminated; or

(c) The nonparty NCP is known but deceased.

(7) DCS determines the support obligation of the party NCP without regard to:

(a) The amount of the nonparty NCP's support obligation for the same child or children; or

(b) The cost of foster care placement, as provided in WAC 388-14A-8105.
