(a) When a petition seeking an order of income withholding as provided in subsection (a) of Section 30-3-62 is initiated in any case which does not arise pursuant to Title IV-D of the Social Security Act, there shall be collected, by the clerk of the court, the filing fee prescribed for other civil cases, generally, as set forth in Section 12-19-71 and other applicable statutes. The fee shall be collected by the clerk at the time the proceeding is initiated and shall be disbursed as provided in Section 12-19-72 and other appropriate provisions of law. Provided, that when representing or otherwise acting on behalf of the obligee neither the State of Alabama nor any agency thereof, nor any person whom the court finds incapable of payment, upon execution of an affidavit of substantial hardship, as provided in Section 12-19-70, shall be required to pay the fees prescribed by this subsection. The court may order all costs taxed against the obligor to be withheld from the first pay period covered by the support order and, in such instances, to be paid by the employer directly to the clerk of the court. Provided further, the amount of costs taxed against the obligor and withheld from the first pay period shall be over and above any moneys withheld for support, but shall be subject to the limitations of Section 30-3-67.

(b) When an order for income withholding is entered by a court of this state as a part of an original order for the payment of support or as a part of an order in any of the proceedings listed in subsection (a) of Section 30-3-61, there shall be no new or additional filing fee assessed in such cases.
