A marriage license is your official permission slip to tie the knot in Illinois. It’s a legal must-have before you make your union official. Without it, even the most beautiful ceremony won’t hold legal weight. Think of it as step one—get the license, have the ceremony, and then make it official with a signed certificate!

Types of Illinois Marriage Licenses

Before tying the knot, know which marriage license suits you.

Regular Marriage License

Available to any couple, regardless of gender. Valid for 60 days from issuance and must be used within the state of Illinois. Both applicants must appear in person to apply.

Civil Union License

Provides legal recognition similar to marriage but is separate from a marriage license. Available to both same-sex and opposite-sex couples. Civil unions offer many of the same legal rights and responsibilities as marriage under Illinois law.

Where to Apply for a Illinois
Marriage License?

If You’re in Illinois

To apply for an Illinois marriage license, visit the County Clerk’s office in the county where you plan to get married. Both partners must appear in person with valid IDs, provide necessary documentation, and pay the required fee. The license is valid for 60 days and can only be used in the county where it was issued. A 24-hour waiting period applies before the ceremony can take place.

If You’re in the U.S. but Outside Illinois

Apply for an Illinois marriage license at the county clerk’s office in the county where you plan to marry. Both applicants must appear in person; licenses cannot be obtained remotely. Illinois law prohibits issuing a marriage license if the marriage would be illegal in the applicant’s home state.

If You’re Outside the U.S.

If you're outside the U.S., you can't apply for an Illinois marriage license remotely. You must appear in person at a county clerk's office in Illinois. Both parties must be present with valid identification.

No matter where you’re located, Courtly simplifies the process, helping you secure your online marriage license easily and legally.

When to Apply for a Illinois Marriage License?

License Validity Period

Marriage licenses in most states expire within 30–90 days. Make sure to check your state’s rules to avoid last-minute stress.

Why Apply in Advance

Processing times can vary. Applying early helps you avoid delays, especially if your wedding is on a weekend or during peak season.

Application Timeline

Some states allow same-day issuance, while others require a waiting period. Plan ahead to meet your wedding timeline.

Receiving Your License

Most offices issue licenses immediately, though some may take a few days. Confirm whether you’ll need to pick it up or if a digital copy is available.

Consequences of Not Using the License in Time

If your license expires before your wedding, you’ll need to reapply—and repay the fees again. Stay on top of the deadline to avoid extra hassle.
