(b) Every support order heretofore or hereafter entered by a court of competent jurisdiction is considered to provide for an order of income withholding, notwithstanding the fact that the support order does not in fact provide for an order of withholding. Income withholding may be instituted under this part for any arrearage without the necessity of additional judicial or legal action.
(c) Every such order as described in subsection (a) of this section shall contain language authorizing income withholding for both current support and for any arrearages to commence without further court action as follows:
The order shall provide that income withholding shall begin immediately, without regard to whether there is an arrearage;
(A) When a child for whom support is ordered is included or becomes included in a grant of assistance from the division of human services or a similar agency of a sister state for temporary assistance for needy families benefits, medical assistance only benefits or foster care benefits and is referred to the bureau for child support enforcement; or
(B) When the support obligee has applied for services from the bureau for child support enforcement created pursuant to section 18-101, et seq., of this chapter, or the support enforcement agency of another state or is otherwise receiving services from the bureau for child support enforcement as provided for in this chapter. In any case where one of the parties demonstrates, and the court finds, that there is good cause not to require immediate income withholding, or in any case where there is filed with the court a written agreement between the parties which provides for an alternative arrangement, such order shall not provide for income withholding to begin immediately, pursuant to section four hundred three, article fourteen of this chapter.
