B. Every initial order entered on or after July 1, 1995, directing a person to pay child support shall include a provision for immediate withholding from the income of the obligor for the amount of the support order, plus an amount for the liquidation of arrearages, if any, unless the obligor and either the obligee or the Department on behalf of the obligee, agree in writing to an alternative payment arrangement or one of the parties demonstrates and the court finds good cause for not imposing immediate withholding. In determining whether good cause is shown, the court shall consider the obligor’s past financial responsibility, history of prior payment under any support order, and any other matter that the court considers relevant to the likelihood of payment in accordance with the support order. An alternative payment arrangement may include but is not limited to, a voluntary income assignment pursuant to § 20-79.1 or 63.2-1945. An order that modifies an initial order may include a provision for immediate income withholding. The total amount withheld shall not exceed the maximum amount permitted under § 34-29. A withholding order issued to an obligor’s employer pursuant to this section shall conform to § 20-79.3. The rights and obligations of the employer with respect to the order are set out in § 20-79.3. The order shall direct the employer to forward payments to the Department for recording and disbursement to the obligee, or as otherwise required by law. The Department shall not charge a fee for recording and disbursing payments when it is providing support enforcement services to the obligee pursuant to § 63.2-1904 or 63.2-1908.
