(a) An obligee shall notify the clerk of the court, or the Department of Human Resources or its designee, whichever office is collecting the support payments which have been ordered withheld, of any change in address of the obligee.

(b) If the clerk of the court, the department or its designee is unable to deliver payments under the order for a period of three consecutive months due to the obligee's failure to notify either of them of an address change, the clerk, the department or its designee shall not attempt further payment under the order and shall, upon the court's order, return the payments to the employer and the court shall terminate the income withholding order upon request.
