How do I get a marriage license in Illinois?

Illinois requires county-specific application and a one-day delay before the ceremony.

1. Where to Apply

The county clerk in the Illinois county where the wedding will be held (750 ILCS 5/203).

Both parties must appear; the license is only valid in that county.

2. ID and Documents

Government-issued photo ID and Social Security number.

If previously married, bring proof of divorce or death of prior spouse.

3. Fees

$30-$100 by county (Cook County $60; collar counties $30-$75).

4. Waiting Period and Expiration

No traditional waiting period, but the license becomes effective the day after issuance (750 ILCS 5/207) — you cannot marry same-day.

Valid for 60 days from issuance.

5. Age and Residency

18 minimum. 16-17 may marry with judicial approval and parental consent (750 ILCS 5/208).

No residency requirement — but ceremony must occur in the issuing county.

6. Blood Test and Same-Sex Marriage

No blood test required (eliminated 1989).

Same-sex marriage legal since the Illinois Religious Freedom and Marriage Fairness Act (effective June 1, 2014), confirmed by Obergefell (2015).
