In the event that income withholding is suspended in the first instance, it shall take effect immediately:--
Income withholding pursuant to this section shall terminate when the underlying support obligation terminates and all arrears are paid. With respect to a case receiving IV-D services, when an obligor changes employers or other source of periodic income, the obligor shall promptly notify his subsequent employer or other source of periodic income of his child support order and the IV-D agency of his subsequent employment or other source of periodic income and within 2 business days of receipt of the information, the IV-D agency shall transfer the income withholding order or the national medical support notice or both to the subsequent employer or other source of periodic income. With respect to a case receiving IV-D services, if an income withholding order or order for health care coverage is in effect under this section but cannot be executed because the obligor has no employer or other source of periodic income, said agency shall send the income withholding order or national medical support notice or both, together with notice of the provisions of subsection (f), to an employer or other source of periodic income who later employs or pays the obligor as soon as the new such employment or other source of periodic income is ascertained. With respect to a case receiving IV-D services, if an order for health care coverage is in effect but cannot be executed because health care coverage is not available to the obligor at reasonable cost, said agency shall send the national medical support notice to a provider of health care coverage together with notice of the provisions of subsection (f) as soon as the availability of such health care coverage is ascertained. Such provider shall enroll the child for whom the national medical support notice applies, notwithstanding the employee's failure to sign or submit an application for enrollment for health care coverage and without regard to any restrictions on enrollment periods. The provider shall not refuse to enroll the child for whom the national medical support notice applies on the grounds stated in subsection (m) and shall not suspend such coverage while it is available to the obligor unless the court which entered the original order, at the request of the obligor, determines that such coverage is not available to the obligor at reasonable cost, or otherwise creates an undue hardship upon the obligor.
If the court or hearing officer orders that income withholding be suspended, upon notice to the IV-D agency, said agency shall promptly notify the employer or other source of periodic income.
