Missouri Marriage Age Requirements

Most states, including Missouri, have requirements for how old you must be to get married, either with or without parental consent. These laws are intended to protect minors from being coerced into marriage or getting married before they're mature enough to make such a commitment. However, state laws also typically allow those younger than the minimum age to get married in the event of a pregnancy with court approval.

Overview of Missouri Marriage Age Requirement Laws

The "Show-Me" state previously allowed minors younger than 15 to get married "under special circumstances and for good cause." For example, a 14-year-old girl who is pregnant may meet the "special circumstances" requirement, but also must want to get married for "good cause." If the father is supportive and the marriage is in the best interests of the young family, then the court likely would grant a court order for the marriage license.

In July 2018, Missouri's governor signed a bill raising the minimum age of marriage with parental consent to 16. Additionally, the bill prevents anyone 21 or older to marry someone under the age of 18. This bill went into effect in August 2018.

Getting a Marriage License in Missouri

The Recorder of Deeds in each Missouri county is authorized to issue marriage licenses within the state, while both applicants must appear in person and present valid identification. The person performing the marriage ceremony must return the license to the Recorder of Deeds within 15 days of the ceremony.
