The couple must purchase their marriage license in the county where the ceremony will be held, at least 1 day before the ceremony takes place, and bring it with them to be signed by the officiant.
It’s the wedding officiant’s responsibility to complete the marriage license (the bottom front portion of the document) after the wedding ceremony and return it so that it can be filed. The officiant must return the completed license to the clerk’s office where it was issued within ten days (10) of the ceremony, either by mailing it in or returning it in person.
Note: Couples may be asked to provide an address for their wedding venue when applying for their license, so that the clerk’s office can confirm the venue is in their jurisdiction.

The image below shows the bottom portion of the marriage license (the certificate), which must be completed by the officiant. This is the only part of the document you need to fill out. This example is from the Du Page County Clerk’s office.

Above: These helpful instructions from the DuPage County Clerk include a small sample of the marriage license. Your license may not look identical, however you will see similar fields, including spaces to print and sign your name, to write your title (write "Minister," if you are ordained with AMM), date and location, and optional witnesses.
If you make a mistake while filling out the marriage license – such as a misspelled name or incorrect date – the couple may need to purchase a replacement license to fill in with the accurate information. Do not use white-out, correctional fluid or tape on the marriage license, as this will invalidate the form.
Since different counties have different steps to take to correct different types of errors, we recommend you contact the issuing clerk’s office directly with your questions. This will be the simplest way to handle any issues that come up.
Amending an Illinois marriage record after it’s been filed is possible, depending on the type of correction that’s needed. The type of correction / amendment also determines how the change is made: either by obtaining a court order, filing an affidavit, or providing certified documents to officials. To start the correction process, and to ask questions about what’s needed in your unique case, contact the clerk’s office where your license was filed directly.
Yes, ministers who are ordained online through a reputable and recognized church, including American Marriage Ministries, can officiate weddings in Illinois and sign your marriage license.

However, not all online-ordained ministers are legally qualified to perform marriages in all states. If your officiant is ordained online with a church other than American Marriage Ministries, it’s important to verify their minister credentials before they perform your wedding ceremony:
Illinois doesn’t require minister registration. This means that once an officiant has been ordained by a reputable online church, they can perform your ceremony.
Marriage license prices may vary slightly by county, and sometimes increase to keep up with state budget costs. For the most-current Illinois marriage license cost, click the link below, or contact your local clerk’s office:
The amount of time you spend in the clerk’s office will vary depending on where you apply – some offices allow walk-ins, while others require each couple to make an appointment. After completing the application, there is a 1-day waiting period to marry. This means you must wait until at least the next day to have your wedding ceremony.
Some couples may qualify for a waiting period waiver (at the court’s discretion). Learn more about marriage license waiting periods and waivers by clicking the link below:
How long a marriage license is valid in each state is called the “expiration period.” This is the number of days or months you have to use your license after it’s issued – your ceremony must take place within this timeframe. To see the current Illinois marriage license expiration period, click the link below:
You have several options for ordering a certified copy of your marriage record in Illinois. The first (and often fastest) method is to visit the office of record in person to request a copy. The second method is to order a copy online using the VitalChek portal for the issuing city / town. The third option is to request a copy of your marriage record by mail from the Vital Records office in the town where it was filed. Contact your clerk’s office for the mailing address and specific instructions.
If you need a replacement copy of a marriage license before it’s been filed, contact the issuing office directly for next steps.
