(750 ILCS 46/301)
A parent-child relationship may be established voluntarily by the signing and witnessing of a voluntary acknowledgment in accordance with Section 12 of the Vital Records Act and Section 10-17.7 of the Illinois Public Aid Code. The voluntary acknowledgment shall contain the social security numbers or tax identification numbers of the persons signing the voluntary acknowledgment; however, failure to include the social security numbers of the persons signing a voluntary acknowledgment does not invalidate the voluntary acknowledgment.
