  • Social Security Number — required on the application for both parties. Physical card not required.

After the Ceremony

After your ceremony, the officiant must sign and return the marriage license to the Lake County Clerk within the period specified by Illinois law.

Frequently Asked Questions

Appointment requirements vary and can change. Some counties moved to appointment-only during the pandemic and stayed that way; others reverted to walk-in. Call the Lake County Clerk's office directly before your visit to confirm the current policy.

No — a Lake County marriage license is only valid for ceremonies performed within Illinois. If your ceremony will be in a different state, you must apply for a license in that state. Your home state will recognize a legally performed marriage from any other state.

You don't need to notify the clerk of a date change — the license is simply valid until it expires (60 days from issue). If your new date falls outside the validity window, you'll need to reapply. If it falls within the window but after any applicable waiting period, you're fine.
