Understanding Missouri Marriage License Requirements

A Missouri marriage license is a legal document issued by the state that gives you permission to marry. Before you can have a wedding ceremony, both people getting married must obtain this license from a Missouri circuit court in the county where at least one person lives. The license serves as official proof that your marriage is recognized by the state, which matters for taxes, insurance, hospital visitation rights, and many other legal situations.

Missouri has specific rules about who can get married in the state. Both people must be at least 18 years old. If you are 16 or 17, you can marry with written consent from your parents or guardians and approval from a judge. The two people getting married must not be related by blood in ways that Missouri law prohibits—for example, you cannot marry your sibling, parent, or child. Also, you cannot marry someone who is already legally married to another person.

The state does not require you to live in Missouri to get married there, but at least one person must be a resident of the specific county where you apply. This means if you live out of state, you can still get a Missouri marriage license if your future spouse lives in Missouri. Some couples choose to marry in Missouri for various personal, family, or cultural reasons, even if they live elsewhere.

Missouri does not require blood tests, physical examinations, or waiting periods before marriage. This is different from some other states that have additional steps. However, you do need to provide certain documents and information when you apply at the circuit court. Understanding these basic requirements helps you gather the right paperwork and avoid delays when you visit the courthouse.

Practical Takeaway: Before starting the process, confirm that both people meet Missouri's basic requirements: are 18 or older (or have parental consent if 16-17), are not already married, and are not too closely related. If one person lives outside Missouri, make sure the other person lives in the county where you plan to apply.

Documents and Information You Will Need

When you go to the circuit court to get your marriage license, you must bring specific documents that prove your identity and age. A valid government-issued photo ID is the standard requirement. This can be a driver's license, passport, military ID, or state ID card. The ID must be current and show your photograph, full legal name, and date of birth. If your ID has expired but you have another valid photo ID, you may use that instead, though some courts prefer current IDs.

You will also need to provide your Social Security number. The court uses this to check for any legal reasons you cannot marry, such as outstanding child support orders or existing marriage records. You do not need to bring a Social Security card—you can simply tell the clerk your number, which they will verify in their system. If you do not have a Social Security number, contact the circuit court in advance to learn what alternative information they accept.

Both people applying for the license must appear in person at the courthouse. You cannot send someone to apply on your behalf, and you cannot apply by mail or online in Missouri. This means you both need to plan to visit the circuit court at the same time. The court will ask you standard questions such as your full legal name, date of birth, current address, and whether you have been married before. Bring any documents that show name changes if you have changed your name through marriage, divorce, or court order.

If you were previously married, you may need to bring proof that the previous marriage ended. This could be a divorce decree, annulment papers, or a death certificate if your previous spouse passed away. Keep a copy of these documents with you when you go to the courthouse. Courts in different counties may have slightly different preferences about what they want to see, so calling ahead can save time.

Some applicants may need additional documents. For example, if you are getting married at age 16 or 17, you must bring written parental consent forms and be prepared for a judge to review your situation. Non-U.S. citizens should bring their passport or immigration documents. Having all required documents ready prevents delays and makes the process faster.

Practical Takeaway: Create a checklist before your courthouse visit: valid photo ID for both people, Social Security numbers written down, proof of any name changes, and if applicable, divorce decrees or annulment papers from previous marriages. Call your county circuit court one day in advance to confirm their specific document requirements.

How to Find Your Local County Circuit Court

Missouri has 114 counties, plus the City of St. Louis which functions as its own county for government purposes. Each county has a circuit court that issues marriage licenses. To find the correct courthouse, you need to know which county you or your future spouse lives in. If you are unsure of your county, you can find it by entering your address into the Missouri Secretary of State website or by searching online for "[your city or town name] Missouri county."

Once you know your county, search online for "[county name] Missouri circuit court marriage license" or "[county name] Missouri clerk of court." The clerk's office handles marriage licenses in most Missouri counties. Many court websites now list their hours, phone numbers, and specific procedures for getting a marriage license. Some counties have detailed instructions on their websites, while others provide basic information and recommend calling for specifics.

Court offices are typically open Monday through Friday during regular business hours, usually 8 a.m. to 5 p.m., though hours vary by county. Some courthouses close for lunch, so calling ahead ensures someone will be available when you arrive. During holiday weeks, courthouse hours may change, so if you are planning to get married during Thanksgiving, Christmas, or another holiday period, confirm the schedule in advance. A quick phone call can tell you exactly when the marriage license office is open and what documents to bring.

When you call or visit in person, ask about the fee. Missouri marriage license fees vary by county but typically range from $25 to $65. Some counties accept cash, check, or credit card, while others may only take certain payment methods. Knowing this ahead of time means you can bring the correct payment method and complete the process without delay. A few counties may allow you to pay online before coming in, though this is less common.

If you live in one county but your future spouse lives in a different county, you can apply in either county—whichever is more convenient for you. However, you can only apply in counties where at least one of you actually lives. Proof of residency is not usually required, but the clerk may ask where you live. If the courthouse is far from your home, consider applying online (if available) or calling to confirm that both people meet the requirements before making the trip.

Practical Takeaway: Use the Missouri Secretary of State website or a simple internet search to identify your county, then locate the phone number for your county circuit court or clerk of court. Call at least a few days before you plan to visit, ask about hours, fees, payment methods, and any county-specific requirements. This five-minute call prevents frustration and wasted trips.

The Marriage License Application and Waiting Periods

When you arrive at the courthouse with your documents, the clerk will give you a marriage license application form to fill out. The form asks for standard information: your full legal name exactly as it appears on your ID, date of birth, current address, and Social Security number. You will provide the same information for your future spouse. The form also asks if either of you has been married before, where previous marriages took place, and how they ended. Answer these questions truthfully and completely.

The clerk will review your application for accuracy and completeness. They will check your ID to make sure the name and date of birth match what you wrote on the form. They will ask if you have any legal barriers to marriage, such as existing marriage records in Missouri or other states. If everything is in order, they will issue your marriage license on the spot. You do not need to return to the courthouse or wait for approval—the license is ready the same day in almost all cases.

Missouri has no waiting period between when you receive your marriage license and when you can have your wedding ceremony. This is different from states that require you to wait several days after receiving the license. In Missouri, you can receive your license on a Tuesday and have your wedding on Wednesday if you wish. The license is valid for 30 days from the date it is issued. This means you must have your wedding ceremony within 30 days, or the license expires and you must apply for a new one.

The license must be used in Missouri. A Missouri marriage license is only valid for ceremonies performed within the state. If you plan to have your wedding in another
