    Sec. 10-10.4. Payment of Support to State Disbursement Unit.
    (a) As used in this Section:
    "Order for support", "obligor", "obligee", and "payor" mean those terms as defined in the Income Withholding for Support Act, except that "order for support" shall not mean orders providing for spousal maintenance under which there is no child support obligation.
    (b) Notwithstanding any other provision of this Code to the contrary, each court or administrative order for support entered or modified on or after October 1, 1999 shall require that support payments be made to the State Disbursement Unit established under Section 10-26 if:
        (1) a party to the order is receiving child support
    
enforcement services under this Article X; or
        (2) no party to the order is receiving child support
    
enforcement services, but the support payments are made through income withholding.
    (c) Support payments shall be made to the State Disbursement Unit if:
        (1) the order for support was entered before October
    
1, 1999, and a party to the order is receiving child support enforcement services under this Article X; or
        (2) no party to the order is receiving child support
    
enforcement services, and the support payments are being made through income withholding.
    (c-5) If no party to the order is receiving child support enforcement services under this Article X, and the support payments are not being made through income withholding, then support payments shall be made as directed in the order for support.
    (c-10) At any time, and notwithstanding the existence of an order directing payments to be made elsewhere, the Department of Healthcare and Family Services may provide notice to the obligor and, where applicable, to the obligor's payor:
        (1) to make support payments to the State
    
Disbursement Unit if:
            (A) a party to the order for support is receiving
        
child support enforcement services under this Article X; or
            (B) no party to the order for support is
        
receiving child support enforcement services under this Article X, but the support payments are made through income withholding; or
        (2) to make support payments to the State
    
Disbursement Unit of another state upon request of another state's Title IV-D child support enforcement agency, in accordance with the requirements of Title IV, Part D of the Social Security Act and regulations promulgated under that Part D.
    (c-15) Within 15 days after the effective date of this amendatory Act of the 91st General Assembly, the clerk of the circuit court shall provide written notice to the obligor to make payments directly to the clerk of the circuit court if no party to the order is receiving child support enforcement services under this Article X, the support payments are not made through income withholding, and the order for support requires support payments to be made directly to the clerk of the circuit court.
    (c-20) If the State Disbursement Unit receives a support payment that was not appropriately made to the Unit under this Section, the Unit shall immediately return the payment to the sender, including, if possible, instructions detailing where to send the support payments.
    (d) The notices under subsections (c-10) and (c-15) may be sent by ordinary mail, certified mail, return receipt requested, facsimile transmission, or other electronic process, or may be served upon the obligor or payor using any method provided by law for service of a summons. A copy of the notice shall be provided to the obligee and, when the order for support was entered by the court, to the clerk of the court.
