How can a 16 year old change her last name in the state of California?

In California, a 16-year-old can change her last name by filing a petition for a name change in the local superior court. This process typically requires parental consent, and the court may also require a hearing. The minor must provide reasons for the name change and may need to publish the name change request in a local newspaper. After the court approves the petition, the new name will be officially recognized.
