In most states you can petition to change your name on your own once you turn 18. Alabama and Nebraska set that age at 19, and Mississippi sets it at 21. Below your state’s age of majority, a parent or legal guardian has to file the petition for you. Marriage and divorce create their own name-change pathways that skip the court petition entirely, and a legally emancipated minor can file as an adult would. So the real answer to what age can you change your name depends on which of those situations you’re in.
The Age of Majority in Your State
The age at which you can file a name-change petition on your own tracks your state’s age of majority. For most of the country that’s 18. Alabama and Nebraska set it at 19. Mississippi sets it at 21. Once you hit that threshold, courts routinely approve adult name changes for virtually any personal reason.
What a judge is looking for is good faith. A petition will be denied if the court believes you’re trying to dodge debts, avoid a criminal record, mislead someone, or commit fraud. Some states also require you to disclose pending criminal charges or outstanding warrants in the petition itself. These checks apply regardless of your age; turning 18 gives you the right to file, not a guarantee of approval.
When a Minor Wants to Change Their Name
A child under the age of majority cannot file independently. A parent or legal guardian has to initiate the process on the child’s behalf.
The cleanest version is when both legal parents sign a written, notarized consent and submit it with the petition. When both parents agree, courts rarely push back. Things get harder when one parent objects. The nonconsenting parent can file a formal objection, which triggers a hearing where both sides argue the point. If a parent can’t be located at all, the petitioning parent usually has to show they made a genuine effort to find them, which can mean publishing a legal notice in a local newspaper or conducting a formal search.
In every case involving a child, the judge decides under the “best interest of the child” standard. That means weighing the child’s relationship with each parent, how long the child has used the current name, and whether the change would benefit or harm the child.
When a Minor’s Own Preference Counts
A child’s own wishes carry more weight the older they get. Many jurisdictions set a specific age, commonly around 14, at which a minor’s opinion becomes a formal part of the process. In those states the court will take the teenager’s preference seriously, and some require the minor to provide written consent before the change can proceed.
A few states consider the wishes of children as young as 10, though at that age the preference is one factor among many rather than a deciding one. The younger the child, the more the judge is relying on the parents and the best-interest analysis rather than the child’s stated view.
Emancipated Minors
If you’re a minor who has been legally emancipated, meaning a court has granted you adult legal status before the usual age of majority, you can generally petition for a name change on your own. Emancipation effectively removes the requirement for parental involvement.
Marriage and Divorce Don’t Depend on Age the Same Way
Marriage and divorce are the most common reasons people change names, and neither requires a separate court petition. That matters here because these pathways don’t line up with the age-of-majority rule the way an ordinary petition does. If you’re legally married, your marriage certificate is itself the authorizing document for the new name; you present a certified copy to government agencies and update your records.
Divorce works the same way if you plan ahead. Most states let you include a name-restoration request in the divorce petition. When the judge signs the final decree with that provision included, you revert to your prior name using the certified decree as proof. No separate filing, no extra fee. Skip the step during the divorce and change your mind later, and you’re back to the standard court petition.
Good-Faith Limits That Apply at Any Age
Age is the gatekeeping question, but it isn’t the only one. A couple of limits apply no matter how old you are.
The first is content. Most states restrict what your new name can include. Numbers, symbols, and pictographs are prohibited in the majority of jurisdictions, though a handful of states allow them. Obscene or threatening language will also get a petition rejected.
The second is a criminal record. Roughly a third of states impose some restriction on name changes for people with felony convictions. Some bar anyone with a felony from changing their name until a waiting period passes after they complete their sentence, including probation and parole. Others permanently prohibit name changes for people convicted of certain violent or sexual offenses, with narrow exceptions for marriage, divorce, or adoption.
Registered sex offenders face especially tight restrictions. Several states flatly prohibit them from changing their names. States that do allow it typically require the offender to update their registry information within a short window, often 10 days. At the federal level, anyone required to register under the Sex Offender Registration and Notification Act who knowingly fails to update their registration, including after a name change, faces up to 10 years in prison.1Office of the Law Revision Counsel. 18 USC 2250 – Failure to Register
Even in states without an explicit statutory restriction, judges keep discretion. A felony conviction surfacing in a background check will factor into whether the judge believes the petition is in good faith. A clear, honest explanation at the hearing goes a long way.
So the short version. In most states, 18. In Alabama and Nebraska, 19. In Mississippi, 21. Younger than that, a parent or guardian files for you, with the court weighing your best interest and, past about 14 in many states, your own stated preference. Marriage, divorce, and emancipation each open their own doors on a different timetable.
