In Illinois, gestational surrogacy is permitted under the Illinois Gestational Surrogacy Act 750 ILCS 47/1 – 47/75 (http://www.ilga.gov/legislation/ilcs/ilcs3.asp?ActID=2613&ChapterID=59). It’s a surrogacy-friendly Statute that guides the process from contract formation through the issuance of the birth certificate. It applies, however, only to arrangements in which one or both intended parents has/have contributed a gamete to form the embryo.
Traditional (genetic) surrogacy in Illinois is not covered under this statute; it is permitted because no statute or case law prohibits it.
