If the Department of Revenue decides that you have not paid the court-ordered child support, it must send you a written notice, at least once per year. The notice must state the amount of unpaid support as of the date of the notice and your right to request an Administrative Review by filing a written request, including sufficient documentation, with the DOR within 30 days of the date of the notice.
If you think that the DOR made a mistake in figuring that you owe unpaid child support, you can file a written request for an Administrative Review. You have to file the request for Administrative Review within 30 days of the DOR's notice to you of unpaid child support. If you have documentation that show that you have paid more child support than DOR has given you credit for, send copies to the DOR with your request for Administrative Review.
If you file the written request for an Administrative Review within the 30 days, the DOR must conduct the review within 30 days of the request and may not start any further administrative enforcement action (such as levying on your bank account) until the review is completed.
You can start the process of requesting an Administrative Review by calling the DOR Child Support Enforcement Division Customer Service Bureau at 1-800-332-2733.
Upon receipt of the necessary information and documentation, the DOR conducts the Administrative Review, makes a written decision, and sends the decision to the person who requested the review. The decision must also notify you that you can, within 45 days of the decision, seek judicial review by the court where the child support order was issued or registered. The court reviews the decision made by the DOR and may correct any "mistakes of fact."
