If I entered into a same-sex marriage, civil union or domestic partnership in another state, do I need to enter into a civil union again in Illinois?

No. If you entered into a same-sex marriage, civil union, or substantially similar legal relationship in another state, it will be recognized as a civil union in Illinois. You may be required to provide proof of your out-of-state union such as a copy of your marriage or civil union certificate or proof that you and your partner have validly registered as domestic partners.
