When parents need to change a child's legal name
Parents may need to change a child's name for many reasons: after a divorce and remarriage, to reflect an adoption, to correct a name on a birth certificate, or because the child (if old enough) expresses a preference. In every case, a court order is required — you cannot simply start using a different name for a minor.
Each state has its own forms, procedures, and consent requirements. This guide walks you through the legal process, including when both parents must agree, what happens if one parent objects, and which forms you need to file.
Step 1: Determine which court has jurisdiction
In most states, you file a petition for a minor's name change in the same court that handles adult name changes — typically the circuit court, district court, or superior court in the county where the child resides.
Some states have specific forms and procedures for minors. Florida, for example, provides dedicated minor child name change forms (Form 12.982(c) for the petition and Form 12.982(d) for the final judgment). California uses the same Form NC-100 for both adults and minors, with additional attachments for the child's information.
- Florida: Form 12.982(c) (Petition for Change of Minor Child's Name) and Form 12.982(d) (Final Judgment). Available at flcourts.gov.
- California: Form NC-100 (Petition for Change of Name) — same form used for adults and minors. File in Superior Court. Filing fee: $435–$450. Fee waiver: Form FW-001.
- New York: Child Name Change Petition — file in Family Court or Supreme Court depending on the county. NYC Civil Court handles some cases. Fee: $65 (Civil Court) or $210 (Supreme Court).
- Texas: File in District Court. No standardized state form for minors — check with your county clerk.
- Illinois: File a Request for Name Change at Circuit Court. Same forms as adult petitions. Fee: $230–$320.
Step 2: Parental consent — both parents vs. one parent
The most important difference between adult and minor name changes is the consent requirement. In most states, both legal parents must agree to the name change, or the non-consenting parent must be formally notified and given an opportunity to object.
If both parents sign the petition or provide written consent, the process is usually straightforward. If one parent cannot be located, you may need to publish notice or request permission from the court to proceed without their consent.
- Both parents consent: File the petition together or attach signed consent forms. Most courts approve quickly.
- One parent objects: The court schedules a hearing. The judge considers the child's best interest, the child's preference (if old enough, usually 12+), and each parent's reasoning.
- One parent is absent or unknown: You may need to publish notice in a newspaper or file an affidavit explaining the absence. Some states allow service by publication.
- Sole legal custody: If you have sole legal custody documentation, you may be able to proceed without the other parent's consent. Bring your custody order to the hearing.
Step 3: Common scenarios for changing a child's name
Different life situations require slightly different approaches. Here are the most common scenarios:
- Divorce and remarriage: A custodial parent may want the child to take a step-parent's last name. Both biological parents typically must consent. If the other biological parent objects, the court weighs the child's best interest.
- Adoption: When a child is adopted, the name change is usually part of the adoption decree. No separate name change petition is needed — the adoption order includes the new name.
- Paternity establishment: After paternity is established, parents may want to change the child's surname to match the biological father. This requires a petition in most states.
- Child's own request: Older children (usually 12–14+, depending on state) may petition on their own or must give written consent. Judges often ask the child directly about their preference.
- Correcting a birth certificate: If a child's name was misspelled or incorrectly recorded, some states offer an administrative correction through the vital records office without a court petition.
Step 4: The court hearing
Most minor name change cases require a hearing. Both parents and the child (if old enough) may need to attend. The judge reviews the petition, confirms parental consent or hears objections, and determines whether the name change is in the child's best interest.
Hearings are typically brief (10–15 minutes). The judge may ask the child about their preference, especially if they are a teenager. Bring all required documentation: birth certificate, custody orders, consent forms, and your petition.
- Bring the child's original birth certificate.
- Bring custody orders or parenting plan if applicable.
- Bring signed consent forms from both parents (if both agree).
- Be prepared to explain why the name change is in the child's best interest.
- In California, publication may be required unless waived. For gender-related changes, publication is automatically waived under CCP 1277.5.
Step 5: After the court order — updating records
Once the judge grants the name change, obtain certified copies of the court order. You will need them to update the child's records at school, with the pediatrician, on insurance policies, and with the Social Security Administration.
Update SSA first (Form SS-5), then the state birth certificate agency, then school records, insurance, and medical providers.
- Social Security Administration: Form SS-5 with the court order and child's birth certificate.
- Birth certificate: Contact the vital records office in the state where the child was born to request an amended certificate.
- School records: Provide the court order to the school registrar.
- Health insurance and medical providers: Update the name on the insurance policy and notify the pediatrician.
- Passport: If the child has a passport, update it using Form DS-5504 (if issued within the past year) or DS-11.
State-specific considerations
States differ significantly in how they handle minor name changes. Some require both parents to appear at the hearing, while others accept written consent. Some states have age thresholds for the child's own consent.

- Florida: Requires both parents' consent or proof of sole custody. Forms 12.982(c) and 12.982(d) are specifically for minor children.
- California: Uses the same NC-100 form. Filing fee $435–$450. Fee waiver available via FW-001. Publication may be required unless waived.
- New York: File in Family Court ($65 in NYC Civil Court) or Supreme Court ($210). The court may appoint a guardian ad litem for the child in contested cases.
- Texas: District court petition. Both parents must be notified. The child's preference is considered if age 10 or older.
- Illinois: No publication required. Circuit court petition. The court considers the child's best interest using statutory factors.
Frequently asked questions
Q: Can I change my child's name without the other parent's consent? A: It depends on your state and your custody situation. If you have sole legal custody, you may be able to proceed alone. If both parents share legal custody, the court typically requires both parents' consent or will hold a hearing to decide based on the child's best interest.
Q: How old does my child need to be to consent to their own name change? A: This varies by state. In many states, children age 12–14 must give written consent. In Texas, a child age 10 or older must consent. Some states do not specify an age but allow the judge to consider the child's preference.
Q: Does an adoption automatically change the child's name? A: Yes. When an adoption is finalized, the adoption decree includes the child's new name. You do not need a separate name change petition. Use the adoption decree to update the child's Social Security record and birth certificate.
Q: How much does it cost to change a child's name? A: Court filing fees range from $65 (New York City Civil Court) to $450 (California). Fee waivers are available in most states. Additional costs may include certified copies ($1–$5 each) and publication ($50–$200 if required). See our [cost comparison guide](/blog/name-change-cost-by-state-2026).
Q: Can a teenager change their own name? A: In most states, a minor cannot file a name change petition independently until they reach the age of majority (18). However, older teenagers can express their preference to the court during a parent-filed petition, and judges give significant weight to the wishes of mature minors.

Washington Name Change in 2026: District Court Petition, No Newspaper Publication, and SB 6081 Sex-Designation Privacy
A Washington name change runs through district court under RCW 4.24.130 with no newspaper publication requirement, fees that vary by county (King County: $98 filing plus $203.50 recording), and a sealed superior court route for gender identity and safety reasons.
