C. If the debtor believes such property is exempt from this debt, within 10 days of the date of service of the order to withhold, the debtor may file an appeal to the Commissioner stating any exemptions that may be applicable. If the Commissioner receives a timely appeal, a hearing shall be promptly scheduled before a hearing officer upon reasonable notice to the obligee. The Commissioner may delegate authority to conduct the hearing to a duly qualified hearing officer who shall consider the debtor's appeal. Action by the Commissioner under the provisions of this chapter to collect such support debt shall be valid and enforceable during the pendency of any appeal.

A copy of such decision shall also be provided to the obligee. Such decision shall establish whether the debtor's property is exempt under state or federal laws and regulations.
