No. As of this writing, Illinois law prohibits a marriage between two people of the same sex and does not recognize a same-sex marriage performed in a state where it is legal, for example, Massachusetts.
The Illinois Marriage and Dissolution of Marriage Act states that “a marriage between 2 individuals of the same sex” is prohibited. 750 ILCS 5/212(5). The Act goes a step further in declaring that “A marriage between 2 individuals of the same sex is contrary to the public policy of this State.” 750 ILCS 5/213.1. Finally, the Act provides that “if any person residing and intending to continue to reside in [Illinois] shall go to another state or country”, and obtains a prohibited marriage, that marriage will be declared “null and void for all purposes in [Illinois] with the same effect as though such prohibited marriage has been entered into in [Illinois].” 750 ILCS 5/216.
Other governmental entities in Illinois allow individuals to register as “domestic partners.” While this doesn’t give the couple any legal rights, it does give them the opportunity to formally recognize their relationship and provides a basis for some employers to provide employment benefits to the partner of the employee.
How can same-sex couples protect each other and their families? They have to be proactive. They need to seek legal advice and create effective solutions that will legalize their relationship to the greatest extent possible. Some of the keys to such a plan are: financial powers of attorney, medical powers of attorney, partnership agreements, wills and trusts.
