Legal Age to Get Married by State in 2026: Marriage Laws and Parental Consent

The legal age to get married in the United States has been changing rapidly over the past decade, with more than half of all states raising or eliminating exceptions to the 18-year minimum. What was standard practice in many states just ten years ago is now prohibited or significantly restricted. If you are planning a marriage involving anyone under 18, or helping someone navigate this situation, understanding current law in the specific state where the marriage will take place is essential, because the rules vary dramatically and continue to evolve.

The National Trend Toward 18 as the Hard Minimum

Most states set 18 as the default minimum age to marry. Historically, most states allowed marriage under 18 with parental consent, and many allowed marriage at even younger ages with judicial approval. A nationwide movement to end child marriage has resulted in a wave of legislation since 2016. Delaware was the first state to set 18 as an absolute minimum with no exceptions in 2018. Since then, more than 25 states have enacted similar laws setting 18 as a hard floor with no exceptions for parental consent or judicial approval.

States that have set 18 as an absolute minimum with no exceptions as of 2026 include Delaware, New Jersey, Pennsylvania, Rhode Island, Minnesota, New York, Connecticut, Massachusetts, Vermont, New Hampshire, and a growing list of others. In these states, it is simply not legally possible to obtain a marriage license for anyone under 18, regardless of parental consent, pregnancy, or any other circumstance. The clerk who issues marriage licenses does not have discretion to make exceptions.

States That Still Allow Exceptions

A number of states still allow marriage under 18 under specific circumstances. The most common exception structure requires parental consent for marriage at 16 or 17, with judicial approval required for marriages involving anyone younger than 16. In practice, the judicial approval pathway has been used far less frequently since courts started scrutinizing these petitions more carefully. Some states set 16 as the minimum with parental consent, with no pathway at all for anyone younger.

States like Texas and California allow marriage at 16 with parental consent and a judge's approval. Florida allows marriage at 17 with parental consent, and at 16 with judicial approval based on pregnancy or birth of a child. Mississippi and some other southern states have been slower to restrict marriage age and still maintain older exception structures. Anyone seeking to understand current law in a specific state should verify the statute directly, because the legal landscape has been changing so rapidly that information from even a year ago may be outdated.

How Parental Consent Works in Practice

In states that still allow marriage under 18 with parental consent, both parents typically must consent unless one parent is absent, deceased, or has had parental rights terminated. A parent who has sole legal custody may be able to provide consent without the other parent. The consent is usually provided in person at the county clerk's office where the marriage license is issued, with valid identification. Some clerks require notarized consent forms.

Parental consent cannot be given by a stepparent, grandparent, or other relative unless they have legal guardianship or custody of the minor. A legal guardian can provide consent to the same extent a parent can, assuming the guardianship papers grant that authority. Courts that review guardianship applications for the purpose of then obtaining parental consent for marriage have begun scrutinizing these situations more carefully for potential abuse.

What Judges Look for When Judicial Approval Is Required

In states that require a judge's approval for marriage below a certain age, courts have broad discretion to grant or deny the petition. Historically, many judges routinely approved these petitions without significant inquiry. The modern approach in most states that still allow judicial approval is more searching. Courts are supposed to consider whether the marriage is in the best interest of the minor, whether the minor is free from coercion or undue influence, and whether the minor understands the nature and consequences of marriage.

Research by advocacy organizations found that judicial oversight has historically been ineffective at preventing harmful marriages because judges often approved petitions without meaningful investigation, minors rarely had independent legal counsel, and the entire proceeding was brief. Some states have responded by requiring that the minor have an attorney appointed to represent their interests separately from their parents, and requiring more extensive hearings. The effectiveness of these reforms varies by jurisdiction.

International and Cross-State Considerations

A marriage validly performed in one state is generally recognized as valid in other states under the Full Faith and Credit Clause of the Constitution, even if that marriage could not have been performed in the second state. This means a couple who married at 16 in a state that allowed it could move to a state that prohibits marriage under 18 and still be legally married there. However, some states have enacted public policy exceptions and refuse to recognize marriages that would have violated their own age minimums.

Immigration law also intersects with marriage age in important ways. U.S. Citizenship and Immigration Services has policies regarding petitions filed on behalf of spouses who were minors at the time of marriage, and certain age combinations in spousal immigration petitions trigger additional scrutiny. For international marriages, the age requirements of the country where the marriage is performed govern whether the marriage is valid, though U.S. law imposes its own requirements on the recognition of those marriages for immigration purposes.

Emancipated Minors and Marriage

An emancipated minor has been legally recognized as an adult for most purposes before turning 18. In some states, an emancipated minor can marry without parental consent because emancipation removes many of the legal disabilities of minority. Other states specify that emancipation does not eliminate the minimum marriage age requirement. The relationship between emancipation and marriage age varies by state and sometimes requires legal research to determine the answer for a specific situation.

It is worth noting that in some historical cases, minors were being encouraged to seek emancipation specifically to enable marriage, which courts increasingly view as a misuse of the emancipation process. Courts considering emancipation petitions have begun asking about the purpose of the emancipation request, and some have denied emancipation when it appeared the primary motivation was to enable a marriage the parents could not otherwise consent to.
