The California name change process starts in your county superior court, not at the DMV or vital records office

To change your name legally in California, you file a petition with the superior court in the county where you live. The court reviews your request, publishes a notice in a local newspaper, and holds a hearing. If the judge approves, you receive a court order that becomes your legal name change document. This order is what you then take to the DMV, Social Security Administration, and other agencies to update your records.

You do not need a lawyer to do this, though some people hire one. The filing fees vary by county but typically range from $200 to $400. The entire process usually takes two to three months from the day you file until you have the final court order in hand.

Key Takeaways

  • You file your petition in the superior court of the county where you live, not online or by mail to a state office.
  • California requires you to publish a notice of your name change in a local newspaper, which costs $50 to $150 and takes about two weeks.
  • You must attend a court hearing, though in many counties the judge will approve your petition without asking questions if you meet the basic requirements.
  • The court order you receive is the official document you use to change your name with the DMV, Social Security, your bank, and your employer.
  • Some name changes are faster or simpler—for example, if you are changing your name as part of a divorce or adoption, the process happens within that case.

Step-by-step: Filing your petition in superior court

Start by going to your county superior court's website and downloading the name change petition forms. The main form is called the Petition to Change Name (Form NC-100 in many counties, though some courts use slightly different numbering). You will also need the Order to Show Cause form and a Proposed Judgment form. Print three copies of each—one for the court, one for the newspaper, and one for yourself.

Fill out the petition with your current legal name, the name you want, and your reason for the change. California does not require you to state a reason, but you can write "personal preference" or leave it blank. Include your date of birth, current address, and how long you have lived in California (you must have lived here for at least six months). Sign the petition in front of a notary public—this costs $10 to $20 at a bank, UPS store, or notary service.

Take the completed, notarized petition and the other forms to the superior court clerk's office in your county. Pay the filing fee (call ahead to confirm the exact amount for your county). The clerk will stamp your forms, assign a court date, and give you a case number. Ask the clerk which local newspaper you must publish your notice in—this is usually the newspaper of general circulation in your county.

Publishing your notice in a local newspaper

California law requires you to publish a notice of your petition in a newspaper at least once a week for four consecutive weeks. Call or visit the newspaper's office and ask for the legal notices department. Bring a copy of your petition and the Order to Show Cause form. The newspaper will tell you the cost (typically $50 to $150 depending on the paper and county) and the publication schedule.

The newspaper will publish the notice starting on a date you choose, usually within one to two weeks of when you submit it. You do not have to read the paper yourself—the newspaper will give you an Affidavit of Publication after the four weeks are complete. This document proves to the court that you published the notice as required. Keep this affidavit; you will bring it to your court hearing.

Some counties have a designated legal newspaper that handles all name change notices. If your county clerk tells you to use a specific paper, use that one. If you have a choice, pick whichever newspaper is cheapest and most convenient for you to work with.

Preparing for your court hearing

Your court date will be printed on the Order to Show Cause form the clerk gave you. Arrive at the courthouse 15 minutes early. Bring the original Affidavit of Publication from the newspaper, your notarized petition, a photo ID, and proof that you have lived in California for at least six months (a utility bill, lease, or bank statement with your name and address works).

In most California counties, the judge will approve your petition without asking many questions if you have completed the paperwork correctly and published the notice. Some judges ask why you want to change your name; answer honestly and briefly. You do not need to explain a personal preference or justify your choice. If you are changing your name to avoid fraud or to hide from someone, the judge may ask follow-up questions, but routine name changes are approved quickly.

After the judge approves your petition, the clerk will give you a Judgment and Order to Change Name. This is your official court order. Ask for multiple certified copies (usually $1 to $2 each). You will need these to update your records with the DMV, Social Security Administration, your bank, and your employer.

Updating your records after the court order

Once you have your court order, you can begin changing your name with other agencies. Start with the Social Security Administration, because many other agencies ask for your Social Security card as proof of your legal name. Go to your local Social Security office with your court order and a photo ID. They will issue a new Social Security card with your new name at no cost.

Next, visit the DMV to update your driver's license or state ID. Bring your court order, your new Social Security card, and your current driver's license. The DMV will issue a new license with your new name. If you own a vehicle, you will also need to update your vehicle registration and title with the DMV.

Contact your bank, credit card companies, employer, insurance companies, and any other organizations that have your name on file. Each will have its own process, but all will ask to see your court order. Some may ask for a certified copy. Update your name with the U.S. Postal Service if you want mail forwarded under your new name, though this is optional.

Name changes as part of divorce or adoption

If you are changing your name as part of a divorce, you can request the name change within your divorce petition. The judge can approve both the divorce and the name change in the same order, which is faster than filing a separate petition. Ask your divorce attorney or the court clerk how to include this request in your divorce paperwork.

Similarly, if you are adopting a child or being adopted, the name change can happen as part of the adoption case. The adoption order itself serves as your name change document, so you do not file a separate petition. This process is handled by the attorney managing your adoption.

When you might need a lawyer

Most people complete a name change without a lawyer. The forms are straightforward, and the court process is designed for people representing themselves. However, you may want to consult an attorney if your situation is unusual—for example, if you are changing your name to hide from someone, if you have a criminal record and are concerned about how the judge will view your request, or if you are not sure whether you meet the residency requirement.

If you do hire a lawyer, expect to pay $300 to $800 for a straightforward name change. Some legal aid organizations in California offer free or low-cost help with name changes for people with low incomes. Contact your county bar association or search "legal aid" plus your county name to find local resources.

Frequently Asked Questions

Can I change my name if I have a criminal record?

Yes. California does not prohibit name changes based on criminal history. However, if you are trying to hide from law enforcement or evade a court order, the judge may deny your petition. Be honest with the court about your reasons for the change.

How long does the whole process take?

From filing to receiving your final court order usually takes two to three months. The newspaper publication period alone is four weeks, and the court schedules your hearing after that. Some counties are faster; call your court clerk to ask about typical timelines in your area.

Do I have to publish my name change in the newspaper?

Yes, California law requires publication in a newspaper of general circulation in your county. This is a public notice requirement and cannot be skipped. The newspaper handles the publication for you once you submit the notice.

What if I want to change my child's name?

The process is the same, but you file the petition as the parent or guardian. You will need to show proof of custody or guardianship. If both parents do not agree, the other parent can object at the court hearing, and the judge will decide whether to approve the change.

Can I change my name back to my maiden name without going to court?

If you are divorced, you can request a name change as part of your divorce judgment, which is faster than filing a separate petition. If your divorce is already final, you still need to file a separate name change petition in court—there is no shortcut process for this.
