Couples are responsible for obtaining a valid marriage license from the State of Illinois, with both the bride and groom present. There is a 24-hour waiting period from the time the license is issued. Illinois does not require blood tests or other medical records. License is good for 60 days, anywhere in Illinois.

Any of the following documents will be accepted:

• A valid U.S. driver's license, a valid U.S. state identification card, a valid U.S. passport, a valid U.S. military identification card or a valid Illinois Department of Public Aid card (the I.D. and the medical card).
• Either bring your Social Security card or know your Social Security number.
• Bring cash for license fee. Fee varies depending on County ($15 - $30).
• Both bride and groom must go in person. If your divorce was finalized within 30 days, bring certified copy of the divorce decree stating the 30-day waiting period is waived.
• If you want to use your maiden name on the license bring a certified copy of your birth certificate or a certified copy of your divorce decree that states name is to be changed to maiden name.
• The bride and groom must each be at least 18 years of age to apply for a marriage license without parental consent.
• There are no residency requirements. The marriage license is valid anywhere. Non-residents cannot obtain a marriage license if said marriage would be void in their state.
• A license issued in Cook County cannot be used in any other county or state.
• A divorce decree or death certificate is not required, but a license cannot be obtained before 30 days have passed since a divorce or death.
• License must be signed by the wedding officiate, as well as by witnesses. You'll need copies to change your marital status with insurance companies, the Internal Revenue Service, financial institutions and Social Security.

The preceding legal information is provided as a guideline reference only. Check with the State, County and/or Municipality of your wedding site for more detailed and current information. Check with your home state about its requirements for a blood test, license, and other documents. A marriage license from your home state may not be valid for a ceremony performed in another state, territory or country. A marriage performed in another state may not be recognized by your home state, unless specific requirements are met.
