305 ILCS 5/4-1.7
If the parent or parents of the child are failing to meet or are delinquent in their legal obligation to support the child, the parent or other person having custody of the child or the Department of Healthcare and Family Services may request the law enforcement officer authorized or directed by law to so act to file an action for the enforcement of such remedies as the law provides for the fulfillment of the child support obligation.
If a parent has a judicial remedy against the other parent to compel child support, or if, as the result of an action initiated by or in behalf of one parent against the other, a child support order has been entered in respect to which there is noncompliance or delinquency, or where the order so entered may be changed upon petition to the court to provide additional support, the parent or other person having custody of the child or the Department of Healthcare and Family Services may request the appropriate law enforcement officer to seek enforcement of the remedy, or of the support order, or a change therein to provide additional support. If the law enforcement officer is not authorized by law to so act in these instances, the parent, or if so authorized by law the other person having custody of the child, or the Department of Healthcare and Family Services may initiate an action to enforce these remedies.
A parent or other person having custody of the child must comply with the requirements of Title IV of the federal Social Security Act, and the regulations duly promulgated thereunder, and any rules promulgated by the Illinois Department regarding enforcement of the child support obligation. The Department of Healthcare and Family Services and the Department of Human Services may provide by rule for the grant or continuation of aid to the person for a temporary period if he or she accepts counseling or other services designed to increase his or her motivation to seek enforcement of the child support obligation.
In addition to any other definition of failure or refusal to comply with the requirements of Title IV of the federal Social Security Act, or Illinois Department rule, in the case of failure to attend court hearings, the parent or other person can show cooperation by attending a court hearing or, if a court hearing cannot be scheduled within 14 days following the court hearing that was missed, by signing a statement that the parent or other person is now willing to cooperate in the child support enforcement process and will appear at any later scheduled court date. The parent or other person can show cooperation by signing such a statement only once. If failure to attend the court hearing or other failure to cooperate results in the case being dismissed, such a statement may be signed after 2 months.
No denial or termination of medical assistance pursuant to this Section shall commence during pregnancy of the parent or other person having custody of the child or for 30 days after the termination of such pregnancy. The termination of medical assistance may commence thereafter if the Department of Healthcare and Family Services determines that the failure or refusal to comply with this Section persists. Postponement of denial or termination of medical assistance during pregnancy under this paragraph shall be effective only to the extent it does not conflict with federal law or regulation.
Any evidence a parent or other person having custody of the child gives in order to comply with the requirements of this Section shall not render him or her liable to prosecution under Section 11-35 or 11-40 of the Criminal Code of 2012.
When so requested, the Department of Healthcare and Family Services and the Department of Human Services shall provide such services and assistance as the law enforcement officer may require in connection with the filing of any action hereunder.
The Department of Healthcare and Family Services and the Department of Human Services, as an expense of administration, may also provide applicants for and recipients of aid with such services and assistance, including assumption of the reasonable costs of prosecuting any action or proceeding, as may be necessary to enable them to enforce the child support liability required hereunder.
Nothing in this Section shall be construed as a requirement that an applicant or recipient file an action for dissolution of marriage against his or her spouse.
