The Department shall refer to the State's Attorney, Attorney General, or to the proper legal representative of the unit of government or private agency, for judicial enforcement as herein provided, instances of failure to make parental payments as required by law. Action shall be brought in the circuit court to obtain parental payments and the recovery of such payments may be taken separately or they may be consolidated with actions to obtain other child support. Such actions may be brought in the name of the child receiving care and training, or may be brought in the name of the Department or the unit of local government, as the case requires, in behalf of such persons.
The court may enter orders for the payment of monies for the care and training of the children as may be just and equitable and may direct payment thereof for such period or periods of time as the circumstances require. The order may be entered against the parents or guardians and shall be based upon the standard determined under Section 9.1 or an amount determined by the court to reflect the ability to contribute to the care and training of their children provided by the Department.
When an order is entered for the parental payment for care and training of the child, and the parent or guardian willfully refuses to comply with its enforcement, the parent or guardian may be declared in contempt of court and punished therefor.
