In Texas, there is no single age at which a child gains the right to change their own last name. A parent, managing conservator, or guardian can petition to change a child’s name at any age, but once the child turns 10, the child’s own written consent must be filed with the petition. At 18, the person can file for themselves without any parent involved.1State of Texas. Texas Family Code Chapter 45 – Change of Name
Under Age 10: The Parent Drives the Process
For a child younger than 10, no consent from the child is required by statute. The petition is filed by a parent, managing conservator, or guardian in the county where the child lives. The court will grant the change only if it finds the new name is in the best interest of the child, and that standard applies to every petition regardless of the child’s age.1State of Texas. Texas Family Code Chapter 45 – Change of Name
Even without a written consent requirement, a judge may still ask a younger child about their feelings during the hearing. The best-interest test gives the court room to consider how the child identifies with the current name, how long they’ve used it, and whether the change would strain the child’s bond with either parent or extended family.
Age 10 and Older: Written Consent Is Required
Once the child reaches 10, Texas Family Code Chapter 45 requires the child’s written consent to be attached to the petition.1State of Texas. Texas Family Code Chapter 45 – Change of Name This is a genuine veto. A parent cannot push through a name change over the objection of a child who is at least 10 — if the child refuses to sign, the petition stalls.
This threshold reflects a recognition that children old enough to understand what a name means should have a say in whether theirs changes. It does not, however, let a 10-year-old initiate the petition alone. The parent, managing conservator, or guardian still has to file, and the child cannot walk into a courthouse and request the change on their own no matter how close they are to turning 18.
When One Parent Doesn’t Agree
Every parent whose parental rights have not been terminated is entitled to legal notice of a name change petition, along with any managing conservator or guardian. Notice is typically served through a constable, sheriff, or private process server, following the same rules as other family law cases.1State of Texas. Texas Family Code Chapter 45 – Change of Name
If the other parent agrees, they can waive formal service by filing a signed waiver with the court clerk. The waiver has to be sworn before a notary who is not an attorney in the case, and it cannot use a digitized signature.2State of Texas. Texas Family Code FAM 45.0031 – Waiver of Citation When a parent cannot be found despite reasonable efforts, the petitioner can ask the court for service by publication in a newspaper. An absent parent cannot block the change simply by being unreachable.
A parent who does receive notice has the right to appear and contest the petition. If they do, the petitioning parent carries the burden of showing the change serves the child’s best interest. Courts weigh factors like how long the child has used the current name, the child’s own stated preference (given more weight for older children), whether the request is motivated by alienation from the other parent, and any embarrassment or practical problems the current name causes at school or medical appointments. No single factor decides the case.
At 18: Filing Without a Parent
Turning 18 is the first point at which a Texan can change their last name without a parent’s involvement at all. Adult petitions are governed by Subchapter B of Chapter 45, and the process is more involved than a child’s petition. The petition must include a complete set of fingerprints acceptable to both the Texas Department of Public Safety and the FBI, along with driver’s license numbers, Social Security number, and any criminal history above a Class C misdemeanor.3State of Texas.

The legal standard shifts too. Instead of the “best interest of the child” test, the court must find the change is “in the interest or to the benefit of the petitioner and in the interest of the public.”5Texas State Law Library.

What Goes in the Petition
The petition for a minor is a verified document, meaning the signer swears the contents are true. It has to state the child’s current legal name and place of residence, the full name requested, the reason for the change, whether the child is under the continuing jurisdiction of a court in an existing custody case, and whether the child is subject to sex offender registration requirements.1State of Texas. Texas Family Code Chapter 45 – Change of Name If the child is 10 or older, the child’s written consent is attached.
The statute does not require a birth certificate to accompany the petition, though individual courts sometimes ask for one. Call the district clerk’s office in your county before filing to check for local requirements.
Costs and Updating Records
Filing fees vary by county, generally in the range of a few hundred dollars, with some counties charging around $300 to $350. A petitioner who cannot afford the fee can file an inability-to-pay affidavit asking the court to waive costs. Budget also for service of process charges if the other parent must be formally served, and for certified copies of the court order.
The order by itself does not update government records. Start with Social Security: the SSA requires the original court order (not a photocopy) plus proof of identity, and a parent filing for a minor also needs documentation showing custody or responsibility for the child. There is no fee for the new card.6Social Security Administration.

A mismatch on your tax return can delay a refund.7Internal Revenue Service. Name Changes and Social Security Number Matching Issues
To amend the child’s birth certificate, submit an application to the Texas Department of State Health Services Vital Statistics Unit, notarized and accompanied by a photocopy of acceptable identification and the supporting documentation. Fees vary by amendment type.8Texas Department of State Health Services.

Most institutions will accept a certified copy of the court order.
