305 ILCS 5/11-1
There shall be no discrimination or denial of financial aid and social services on account of the race, religion, color, national origin, sex, marital status, or political affiliation of any applicant or recipient. This paragraph shall not prevent the Department from treating individuals differently as a result of the rights and responsibilities that arise under law from marital status.
Participation in any marriage promotion or family formation activity is voluntary. Non-participation shall not affect any person's eligibility for or receipt of financial aid or social services in any program under this Code.
Where financial aid or social services are granted to certain classes of persons under a program for which federal funds are available, nothing in this Section shall require granting of financial aid or social services to other persons where federal funds would not be available as to those other persons.
