The marriage age by state is 18 as a baseline everywhere in the United States, but more than 30 states still permit 16- or 17-year-olds to marry under specific conditions, usually some mix of parental consent, judicial approval, prior emancipation, or a cap on how much older the other spouse can be. The rules change often, and as of 2025 the map looks very different from what it did a decade ago.1Research file
States Where 18 Is the Hard Floor
In a growing number of states, no one under 18 can marry, period. Parental blessing, pregnancy, a sympathetic judge: none of it matters. The clerk will not issue the license.
Delaware and New Jersey were first, both in 2018. Pennsylvania and Minnesota followed in 2020. Rhode Island and New York closed their exceptions in 2021, Massachusetts in 2022, and Vermont, Connecticut, and Michigan in 2023. Washington, Virginia, and New Hampshire joined in 2024. In 2025, Washington D.C., Maine, Oregon, and Missouri did the same.1Research file
States With 18 as the Floor but an Emancipation Exception
A separate group sets the minimum at 18 but allows a minor to marry if a court has already emancipated them. Georgia, Indiana, Kentucky, Ohio, and Texas work this way. Emancipation is its own court proceeding in which a judge grants a minor adult-level legal independence before they turn 18. In Texas, the clerk will not issue a marriage license to a minor without a certified copy of the emancipation order. The sequence matters in these states: emancipation comes first, and the marriage does not create it.1Research file
States That Allow Marriage at 17
Where 17 is the floor, parental consent is almost always required. Florida, Maryland, Nebraska, Nevada, and Tennessee all permit 17-year-olds to marry. Nevada layers judicial authorization on top of parental approval. Maryland also allows a 17-year-old to marry on proof of pregnancy or the birth of a child.1Research file
States That Allow Marriage at 16
A larger set of states sets the minimum at 16 with parental consent, judicial approval, or both. Alabama, Alaska, Arizona, Arkansas, Colorado, Idaho, Illinois, Iowa, Louisiana, and Montana are among them.1Research file
The procedure typically follows one of two models. In the consent model, a parent signs a notarized affidavit and the clerk issues the license. In the judicial model, the couple petitions a court that independently evaluates whether the marriage serves the minor’s best interests. Colorado is representative of the judicial version: a juvenile court must find the 16- or 17-year-old capable of taking on the responsibilities of marriage, and the court appoints a guardian ad litem to investigate and file a report before any license issues.1Research file
Mississippi
Mississippi is the outlier. Its statute sets different age floors by sex: males must be at least 17, females at least 15. And because Mississippi defines the age of majority as 21 rather than 18, anyone under 21 needs parental consent on a marriage license application, including a 20-year-old.1Research file
Age-Gap Limits on the Older Spouse
Even where a minor is legally old enough to marry, many states now cap how much older the other spouse can be. These limits are designed to prevent an adult from pressuring a teenager into marriage, and they can block a marriage that would otherwise clear every other hurdle.
- Two years: Florida
- Three years: Alaska, Arizona, Colorado, Idaho, Louisiana
- Four years: Georgia, Indiana, North Carolina, Ohio, Tennessee, West Virginia
- Seven years: Utah1Research file
A 16-year-old in Colorado, for example, cannot marry someone 20 or older no matter what a parent or judge says. States without age-gap caps leave that call to parents or judges, an approach child welfare advocates have long criticized as insufficient.1Research file
How Consent and Judicial Approval Actually Work
The procedures for getting a minor married break down into three patterns.
The simplest is parental consent alone. A parent or legal guardian signs a notarized affidavit, the clerk verifies the signature, and the license issues. Alabama, Arkansas, and Nebraska use this model. Both parents typically must consent unless one has sole legal custody or the other parent’s whereabouts are unknown.1Research file
The second is judicial approval, sometimes instead of parental consent and sometimes in addition to it. A judge reviews the circumstances, may interview the parties separately, and decides whether the marriage is in the minor’s best interest. Courts look at maturity, signs of coercion or duress, financial circumstances, and the age gap. This path takes longer and costs more, but it is more protective.1Research file
The third layers both. Iowa and Louisiana require parental consent and a judge’s sign-off before a 16- or 17-year-old can get a license. Neither a parent nor a judge alone has the final word.1Research file
Marriage and Emancipation
In most states, a minor who marries is automatically emancipated by operation of law. The married minor gains the right to sign contracts, lease an apartment, make medical decisions, and otherwise function as a legal adult. Parents lose their duty of support and their authority over the minor’s decisions.1Research file
This is a one-way door. If the marriage ends in divorce or annulment, the emancipation generally stays in effect. The minor does not revert to dependent status. For a 16-year-old whose marriage falls apart six months later, that can mean being legally on their own without a parental safety net and without access to certain resources available only to minors.1Research file
Texas and a few other states invert the sequence: a minor must be emancipated before marrying, so emancipation is a prerequisite rather than a consequence. That effectively adds another judicial checkpoint, because emancipation itself requires its own court proceeding.1Research file
If an Underage Marriage Already Happened
When a minor marries without meeting the state’s legal requirements, the marriage is usually voidable rather than void. The distinction matters. A void marriage is treated as if it never existed. A voidable marriage is legally valid unless and until someone successfully challenges it in court.1Research file
The minor, a parent, or in some states a guardian can petition for an annulment on the ground that the minor was underage and proper consent was not obtained. If the court grants it, the marriage is dissolved as if it never happened. But the window is not open forever: if no one challenges the marriage and the minor reaches 18 and keeps living as a married person, courts in most states will treat the marriage as ratified.1Research file
Because the law in this area has been moving quickly, check the current rule with the county clerk in the state where the license would be issued before relying on any specific minimum age or exception.
