To legally marry in Cook County, Illinois, you must obtain a marriage license from the Cook County Clerk's Office. The license is valid for 90 days and can be used anywhere in the state. Both parties must be present at the same office to apply, and no prior marriage certificate is required if you are a resident. If you are not a resident, you must provide proof of residency or a signed affidavit of intent to reside in Illinois.
Who Can Apply
- Individuals aged 18 or older
- Individuals aged 16–17 with parental consent and a judicial order
- Non-residents must present a valid ID and proof of residency or affidavit
Documents Needed for the Application
The Clerk's Office requires the following:
- Valid government photo ID (driver's license, passport, military ID)
- Social Security Number (if available)
- Proof of residency (utility bill, lease, bank statement)
- Parental consent form for minors (if applicable)
- Completed application form (available online or in person)
Fee Structure and Payment Options
The standard fee for a Cook County marriage license is $60. Payment can be made by:
- Cash (exact change only)

Processing Time and Validity
Once all documents and fees are submitted, the license is issued immediately. The license is valid for 90 days from the date of issuance. You must have a licensed officiant and a ceremony within that period to avoid a renewal.
After Receiving the License
Keep the license in a safe place until your ceremony. You will need to present it to your officiant and, if required, to the city or state for record-keeping. After the wedding, the officiant files the license with the Clerk's Office, finalizing the marriage record.
Common Misconceptions Clarified
No Waiting Period: Illinois has no mandatory waiting period between obtaining the license and marrying. However, some venues or officiants may impose their own waiting times.
Same-Sex Marriages: Cook County fully recognizes same-sex marriages, with no additional requirements beyond the standard application.
Residency Requirements: Non-residents can obtain a license but must provide proof of residency or an affidavit. No residency length is specified, but the affidavit must state intent to reside in Illinois.
Practical Tips for a Smooth Process
- Arrive early to avoid long lines, especially during peak wedding seasons.
- Bring a printed copy of the application and all documents; electronic copies are not accepted.
- Check the Clerk's website for any temporary changes in hours or procedures.
- Ask the clerk for a receipt; it confirms the date of issuance.
