The State Disbursement Unit (SDU) is managed by ACS State & Local Solutions. ACS maintains a secure and interactive Web site for the Illinois SDU, where customers can retrieve child support payment history for the last five transactions.
In order to qualify for federal child support funds, each state must have a centralized unit to receive and distribute child support payments. Child support payments for both IV-D cases (current and former cash or medical assistance cases, as well as others who have requested child support services) and non-IV-D cases (those whose child support is handled privately, generally through private attorneys) are processed through this central unit.
