State Disbursement Unit (SDU): The State Disbursement Unit (SDU) was created by federal mandate to be a disbursement center for all court ordered child support payments within the state of Illinois.

The SDU receives the child support payments, posts them to the correct court order (docket) and mails or electronically transfers the payment to the custodial parent. The payment information is then communicated to the Illinois County where the court order originated. If there is a case for enforcement with the Division of Child Support Services (DCSS), payment information is also communicated to DCSS for proper crediting.

The SDU is simply a clearing house for child support payments for all 102 counties within Illinois. The SDU does not administer any type of enforcement action, serve or terminate income withholding notices, contact employers regarding compliance issues, nor do they maintain balances on support orders or other court order related matters.
