Missouri State Marriage Laws 

Couples planning to tie the knot in Missouri, also known as The Show Me State, must be at least 18 years of age and must provide a social security card and valid photo ID when applying for a marriage license.  Neither blood nor medical tests are required, but there is a three-day waiting period.  In some instances, a judge may waive the waiting period.  The only exception is if either of the intended were formerly married, in which case there is a 30 day waiting period following the legal conclusion of that marriage.  It may be helpful to provide a copy of the divorce decree or former spouse’s death certificate (if applicable). 

Individuals who are under the age of 18 and wish to be married in the state of Missouri must have parental/guardian consent when applying for a marriage license.  Anyone under the age of 15 will require the approval of a county judge, who will typically grant consent for “good cause” or when the marriage is “advisable.” 

The state of Missouri does not have any residential requirements, which means you can exchange vows even if you are not a resident of the state.  Vacationers, former residents and all others are free to tie the knot here.  Once granted, a marriage license is valid for 30 days.  Application and/or marriage license fees may vary by county, which means you must check with the local courthouse regarding the actual cost and acceptable payment methods.  The average cost is $50.00, and it is advisable that applicants have cash on hand in the event that credit cards are not accepted.  An additional $1.00 is charged for each parental consent required. 

Same sex marriage is not permitted in the state of Missouri.  Common law marriages, which are those that a state may acknowledge after a couple has lived together for a certain amount of time, are not recognized in the state.  A wedding can be officiated by a clergyman, either current or retired, or a judge. 

Planning a wedding isn’t state law, but it certainly makes for a more memorable experience.  The official state flower, which is the white hawthorn blossom, would be ideal for a bridal bouquet, wedding decorations, etc.  There are a number of tranquil locations, resorts and tourist destinations that would make Missouri a wonderful choice for an upcoming wedding.
