Civil Union Waiting Period in Illinois? (Spoiler: They Don't Exist)

Illinois does not recognize civil unions since the state legalized same-sex marriage in 2014 (effective June 1, 2014). The Religious Freedom and Marriage Fairness Act converted existing civil unions to marriages automatically.

For a marriage license in Illinois:

• No waiting period. License issued same day; valid 60 days.
• Both parties must appear in person at county clerk's office.
• Fee varies by county (~$30–$60).
• No blood test, residency, or citizenship requirement.

If you entered a civil union in another state before 2014, it is recognized as a marriage in Illinois.
