Jefferson County Marriage License

Jefferson County marriage license applications are handled at the County Clerk's office in Mount Vernon. Both people must appear in person together to sign the form and show valid photo ID. Mount Vernon sits in southern Illinois and serves as the county seat for all vital records in Jefferson County. You do not need to live here to apply. This page walks through what to bring, the one-day waiting period, who can perform the ceremony, and how to get copies of your Jefferson County marriage license after the wedding takes place.

How to Apply in Jefferson County

Head to the Jefferson County Clerk's office in the courthouse in Mount Vernon. Both you and your partner walk in together. You fill out the marriage license application and hand over your IDs. The clerk checks everything, both people sign the form, and then you pay the fee. Under 750 ILCS 5/203, the clerk issues the license once everything is complete. One person alone cannot get it done.

Call the Jefferson County Clerk at (618) 244-8000 before your visit. That way you can confirm office hours, find out the exact fee, and ask about payment methods. The Illinois Association of County Clerks and Recorders lists Jefferson County in their statewide directory if you need a backup way to reach them. Staff at the clerk's office are used to helping first-time applicants and can answer most questions in a quick phone call.

Note: There is no residency rule in Illinois, so couples from any state or country can apply for a Jefferson County marriage license.

Jefferson County Marriage License Requirements

Both people must be at least 18 years old. If you are 16 or 17, you need written consent from both parents, and they must be present at the clerk's office. Nobody under 16 can apply. Bring a valid government-issued photo ID. A driver's license works. So does a state ID, U.S. passport, or military ID card. The IDPH valid ID page lists all accepted forms.

You also provide your full legal name, date and place of birth, Social Security number, current address, and occupation. The clerk asks for both parents' full names. If a prior marriage ended, bring the date, county, and state where it was resolved. A divorce finalized in the last six months means you must show a certified copy of the decree. No blood test is needed. Illinois dropped that rule decades ago. There are no special forms to fill out ahead of time for Jefferson County, but calling to ask if they have an online application is a good idea.

Expired IDs will not be accepted. Make sure your ID is current before you go.

Waiting Period and Validity

Illinois law sets a one-day waiting period. Under 750 ILCS 5/207, your Jefferson County marriage license takes effect the day after the clerk issues it. You cannot use it the same day. Plan to pick up the license at least two days before the ceremony. A court can waive the wait, but that is extremely rare in practice.

Once effective, the license is good for 60 days. After that, it expires. You would need to file a brand new application and pay the fee again. The license is only valid inside Jefferson County. If your ceremony is in Franklin County or Marion County, you need to get a license from that county's clerk instead. Double check the county of your venue before you drive to Mount Vernon.

Jefferson County Marriage Records

After your wedding, the officiant fills out the marriage certificate and returns it to the Jefferson County Clerk within 10 days. This deadline comes from 750 ILCS 5/209 and applies statewide. Once the clerk records the return, you can get certified copies. These are the official proof of your marriage in Jefferson County. You will need them for name changes, legal filings, and insurance updates.

The state of Illinois does not issue certified copies of marriage licenses. The IDPH marriage records page explains that the Department of Public Health can verify a marriage from 1962 to the present for $5. A verification confirms the names, dates of birth, event date, and county. It is not the same as a certified copy. For the full official document, the Jefferson County Clerk in Mount Vernon is your only source.

Under the Vital Records Act (410 ILCS 535), marriage records in Illinois are not public. Only people named on the record, their legal representatives, and a few other categories can access them. This is different from court records, which are generally open to the public. The Jefferson County Clerk follows these state rules for all marriage license requests.

Marriage Ceremony in Jefferson County

Judges, retired judges, religious leaders, and mayors can all officiate weddings in Jefferson County. The mayor of Mount Vernon can perform the ceremony while in office. Under 750 ILCS 5/209, religious leaders from any denomination or faith group may also solemnize a marriage in Illinois. No witnesses are needed by law.

The Jefferson County Clerk is not able to perform ceremonies. That rule only applies to Cook County, where the population is over 2,000,000. If you want a courthouse wedding in Mount Vernon, ask the circuit court about judges who may officiate. Some judges are willing to do it for a small fee. Make sure your officiant returns the signed certificate to the clerk on time. Late returns cause delays when you need copies.

Note: Remind your officiant about the 10-day return deadline before the ceremony so there are no surprises after the wedding.
