How to Change Your Child's Last Name
Get the legal advice you need without the hourly legal fees
You might want to change your child's last name for a number of reasons—after a divorce, when a new step-parent adopts them, or simply to correct a name that was recorded incorrectly at birth. Whatever the reason, the process involves legal steps that vary by state.
Here’s what you need to know about how to change your child’s last name.
Can you change a child’s last name?
Yes, you can generally change a child’s last name through a court petition. However, both biological parents (or legal guardians) typically must consent, or a court must find that a name change is in the best interest of the child. The process is more complex if one parent objects.
Common reasons for changing a child’s last name
- After divorce, a custodial parent wants the child to use their last name
- A stepparent is adopting the child and will share their name
- The biological father was not listed on the birth certificate, but paternity has since been established
- The child’s name was misspelled or recorded incorrectly on the birth certificate
- The parents want to give the child a hyphenated or combined last name
Steps to change a child’s last name
1. Get consent from both parents
In most cases, both parents must agree to the name change. If one parent objects, you’ll need to go to court and demonstrate that the name change serves the child’s best interests. Courts consider factors such as the child’s age and preference, the child’s relationship with each parent, and how a name change would affect them socially and emotionally.
2. File a petition with the court
You’ll need to file a Petition for Change of Name with the appropriate court in your county or state. Forms and filing fees vary by jurisdiction. In many states, the form can be found online through the court’s website.
3. Serve notice to the other parent
The other parent must typically be formally notified (served) with the petition and given an opportunity to respond. If you don’t know where the other parent is, there may be alternative service methods available.
4. Attend a court hearing (if required)
Some states require a court hearing; others will grant an uncontested name change without one. If the other parent contests the change, a hearing is typically required where a judge will decide.
5. Update records
Once the court approves the name change, you’ll need to update the child’s birth certificate, Social Security records, passport, school records, and any other official documents.
Special considerations
If the name change is part of an adoption process, the procedures may differ. Similarly, if the child is a teenager, many courts will consider the child’s own preferences in deciding whether to grant the name change.
