How to Change a Minor Child's Name

Last reviewed July 16, 2026 against official court and .gov sources.

Quick answer

Changing a minor child's name requires a court petition in the county where the child lives. Both parents generally must be notified, and the judge decides based on the child's best interest — not just a parent's preference. The filing fee is usually the same as an adult petition, and some states require a newspaper notice.

Notice and consent are the key difference

A minor name change looks like an adult petition with one major addition: the other parent has rights. In most states you must formally notify the child's other parent so they can consent or object. If the other parent agrees, the process is straightforward. If they object — or can't be located — the court holds a hearing and decides.

When a parent can't be found, ask the court about alternative service, such as service by publication or posting. Courts won't simply skip a parent's right to notice.

The best-interest standard

Judges decide a child's name change on the child's best interest. Factors often include how long the child has used the current name, the child's own preference if old enough, the strength of the child's relationship with each parent, and whether the change could cause confusion or harm. Come prepared to explain why the change helps the child.

Cost and after the order

The filing fee usually matches the adult petition in your state, and fee waivers are available for families who can't afford it. After the judge signs the order, update the child's Social Security record, school records, passport, and medical records. Pick your state above for the exact minor-name-change forms.

Frequently asked questions

Do both parents have to agree to change a child's name?
Both parents generally must be notified. If one objects, the court decides based on the child's best interest. If a parent can't be found, the court may allow alternative service.
How much does it cost to change a child's name?
Usually the same filing fee as an adult petition in your state, and fee waivers are available. Check your state page for the exact amount.
Can a child change their own name?
A minor's name change is filed by a parent or guardian on the child's behalf. Older children's preferences are often considered, but the petition is brought by an adult.
Does a minor name change require publication?
It depends on the state — the same publication rule that applies to adult petitions usually applies. Some states waive it for safety. See your state page.
