Knox County Marriage License

Knox County marriage license records are managed by the County Clerk's office in Galesburg, the county seat. Both people who plan to marry must show up at the clerk's office in person with valid photo ID. There is no way to send just one person or apply by mail. Knox County sits in western Illinois and serves close to 49,000 residents. You can find out what forms you need, the cost of the license, and how the process works on this page. The clerk's office handles all marriage license applications during normal business hours at the Knox County Courthouse.

How to Get a Knox County Marriage License

Walk into the Knox County Clerk's office at the courthouse in Galesburg. Both of you need to be there. Bring a valid photo ID like a driver's license, state ID card, U.S. passport, or military ID. The IDPH valid ID page shows the full list of what counts. You also need your Social Security number, date of birth, and place of birth. The clerk will ask for your parents' full names. That includes your mother's maiden name.

Under 750 ILCS 5/203, the county clerk issues the license once both people sign the form and pay the fee. You fill out the form, show your IDs, pay, and the clerk hands you the license. It does not take effect right away. The one-day wait means you can use it starting the next calendar day. Plan your trip to the Knox County Clerk at least two days before your wedding date so the timing works out.

No blood test is needed. Illinois got rid of that rule back in 1989. There is also no residency rule, so you do not have to live in Knox County or even in Illinois to apply for a marriage license here. Anyone can walk in and apply as long as both people are present and have proper ID.

Knox County Marriage License Requirements

Both people must be 18 or older. Under 750 ILCS 5/208, a person who is 16 or 17 can get a marriage license with consent from both parents. Nobody under 16 can apply in Illinois. The Knox County Clerk checks ages and IDs at the time of the visit. You cannot apply online or by phone. Both people must be present in the office at the same time to sign the form.

If you were married before, the clerk needs details. You must give the date, county, and state where that marriage ended. Was it a divorce or a death? If it ended within the last six months, bring a certified copy of the divorce decree or death certificate. The clerk will not process your Knox County marriage license without that document. This catches some people off guard, so check your records before you go.

The IDPH marriage records page explains that certified copies of marriage records come from the county clerk, not from the state. The screenshot below shows the state's marriage records information.

Knox County follows the same state rules as every other county in Illinois, but fees and office hours can differ. Call (309) 345-3815 if you have questions about your visit.

Note: Bring all your documents in one trip since the clerk will not hold a partial application on file.

Marriage License Fees in Knox County

Marriage license fees vary by county across Illinois. Knox County sets its own rate. Call the clerk's office at (309) 345-3815 to confirm the current fee before you go. Across the state, fees range from about $30 to $90. Some offices take cash only. Others accept checks or cards. Ask about payment methods when you call. A few counties add a small card processing fee on top of the license cost.

Certified copies of a recorded marriage certificate have their own fees. The first copy usually costs more than extras. You can order copies in person at the Knox County Clerk's office or by mail. The Illinois Association of County Clerks and Recorders keeps a directory of all county clerk offices with phone numbers and addresses. Use it to double check the Knox County Clerk's hours and mailing address before you send anything in.

Knox County License Waiting Period

Illinois has a one-day wait. Under 750 ILCS 5/207, the marriage license takes effect the calendar day after it is issued. You cannot use it on the same day you pick it up from the Knox County Clerk. A court can waive this in rare cases, but most couples should plan ahead. Get your license at least one full day before the ceremony.

The license stays valid for 60 days from its effective date. After that it expires. You would have to go back to the Knox County Clerk, fill out a new form, and pay the fee again. And the license only works in Knox County. If your wedding venue is in Peoria County or Henry County, you need a license from that county instead. Double check where your ceremony will take place before you apply. This is one of the most common mistakes couples make.

After Your Knox County Marriage Ceremony

The person who performs the wedding must fill out the marriage certificate and return it to the Knox County Clerk within 10 days. Under 750 ILCS 5/209, this deadline applies to all marriages in Illinois. A late return can cause delays when you need certified copies later. Judges, retired judges, religious leaders, and mayors can all officiate a wedding in Knox County. No witnesses are required by state law.

Once the clerk records the marriage, you can get certified copies. The Knox County Clerk's office handles these in person or by mail. The state does not give out certified copies. Under the Vital Records Act (410 ILCS 535), vital records in Illinois are not public. The IDPH can verify basic marriage facts from 1962 onward for $5, but that is a verification only. For a full certified copy of your Knox County marriage license, contact the clerk's office directly. You can also request a state verification by mailing the Application for Verification of Marriage Record to the IDPH Division of Vital Records in Springfield.

Who Cannot Marry in Knox County

State law sets limits. Under 750 ILCS 5/212, you cannot get a marriage license if you are still in a prior marriage or civil union. Close blood relatives cannot marry. First cousins can marry only if both are over 50 years of age, or if one provides a doctor's note about permanent sterility. The Knox County Clerk checks for these issues during the application process.

Same-sex marriage has been legal in Illinois since June 1, 2014. Knox County issues marriage licenses to all couples who meet the state requirements. There is no difference in the process or fees based on the couple's gender.
