California requires you to go through the court system to change your name legally

A legal name change in California happens through a petition filed in Superior Court in your county. You fill out forms, pay a filing fee, and attend a brief hearing where a judge approves or denies your request. The whole process typically takes four to six weeks from filing to final order, though it can be faster in some counties.

You do not need a lawyer to change your name in California, though you can hire one if you prefer. The court system provides the forms you need, and the process is designed so people can handle it themselves. The main requirements are that you live in California, you are at least 18 years old, and you do not have a criminal intent behind the change (for example, you cannot change your name to evade a court order or hide from law enforcement).

Key Takeaways

  • File a Petition for Change of Name (Form NC-100) in the Superior Court of the county where you live, along with a declaration and proposed order.
  • Pay the filing fee, which varies by county but is typically between $200 and $400; some courts reduce or waive the fee if you cannot afford it.
  • Publish a notice of your petition in a local newspaper for four weeks, which is a legal requirement even if you are changing your name for personal reasons.
  • Attend a hearing where the judge will ask you basic questions about why you want to change your name; most petitions are approved at this stage.
  • Once the judge signs the order, you receive a certified copy that you use to update your name with the Social Security Administration, DMV, and other agencies.

What forms you need and where to get them

The California Judicial Council publishes all the forms you need on its website. The main form is the Petition for Change of Name (Form NC-100). You also need a Declaration Under Penalty of Perjury for Change of Name (Form NC-110), where you explain your reasons for the change, and a Proposed Order for Change of Name (Form NC-120), which the judge will sign if your petition is approved.

You can read these forms from the California Courts website at courts.ca.gov. Look for the "Self-Help Center" or search for "name change forms." Print them out and fill them in by hand or on your computer. The forms include instructions that walk you through what information goes in each blank. If you get stuck on a particular section, the court's self-help center can answer questions by phone or email, though they cannot give you legal information.

Some counties also provide local forms or local instructions that go with the state forms. Before you file, check your county Superior Court's website to see if there are any local requirements or additional forms specific to your court.

Filing your petition and paying the court fee

Once you have filled out the forms, take them to the Superior Court clerk's office in the county where you live. You can file in person, by mail, or online if your county offers e-filing. When you file, you will pay a fee. The amount varies by county—some charge around $200, others charge $400 or more. Ask the clerk what the exact fee is for your county before you go.

If you cannot afford the filing fee, you can ask the court to reduce or waive it. File a Request to Waive Court Fees (Form FW-001) along with your name change petition. You will need to describe your income and expenses so the judge can decide whether to grant the waiver. Many courts approve these requests, so do not skip this step if cost is a barrier.

When you file, the clerk will give you a case number and a hearing date. Write down both. The hearing date is usually set for four to eight weeks after you file, which gives you time to complete the newspaper publication requirement (see below).

Publishing notice in a local newspaper

California law requires you to publish a notice of your name change petition in a newspaper in your county for four consecutive weeks. This is a legal requirement even if you are changing your name for personal reasons and not running from anything. The newspaper publishes a short notice that includes your current name, the name you want to change it to, and the court hearing date.

You do not choose the newspaper yourself. The court clerk will tell you which newspapers are approved for publication in your county, or you can find the list on your county court's website. Call the newspaper and ask about their rates for legal notices. Most charge between $100 and $300 for a four-week publication. Some newspapers offer discounts if you are a low-income person.

The newspaper will handle the publication and send you a proof of publication—a document showing that your notice ran on specific dates. Bring this proof to your hearing. If you do not have proof of publication, the judge will not approve your petition, so do not skip this step.

What happens at your court hearing

On your hearing date, go to the courtroom listed on your paperwork. Arrive a few minutes early. When the judge calls your case, you will stand and answer a few straightforward questions: Why do you want to change your name? How long have you been using the new name (if at all)? Do you have any criminal convictions or outstanding court orders? Are you changing your name for any fraudulent reason?

Most judges approve name change petitions at the hearing. The process is routine, and judges understand that people change their names for many legitimate reasons—personal preference, marriage or divorce, cultural identity, or straightforward wanting a fresh start. As long as you answer honestly and you do not have a criminal intent, your petition will almost certainly be approved.

The judge will sign your Proposed Order for Change of Name right there in court, or the clerk will mail it to you a few days later. Either way, you will receive a certified copy of the order. This is the official document that proves your name has been legally changed.

Updating your name with government agencies and other institutions

Once you have the certified order, you need to update your name in several places. Start with the Social Security Administration. Go to your local Social Security office with your certified court order and a photo ID. They will update your Social Security record, and you will receive a new Social Security card with your new name. This usually takes one to two weeks.

Next, update your name with the California Department of Motor Vehicles (DMV). Bring your certified court order, your current driver's license or ID card, and proof of residence (a utility bill or lease). You can do this in person at any DMV office or by mail. The DMV will issue a new license or ID card with your new name.

After that, update your name with your bank, credit card companies, employer, insurance companies, and any other institutions that have your name on file. Each one has its own process, but they will all ask to see your certified court order. Keep several certified copies of your order—the court clerk can provide them for a small fee—so you have extras as you update different places.

Special situations: name changes for minors and name changes after domestic violence

If you are under 18, a parent or guardian must file the petition on your behalf, and you will need to attend the hearing. The process is the same, but the court wants to make sure the minor is not being forced into the change.

If you are changing your name because of domestic violence, you may be able to skip the newspaper publication requirement. Ask the court clerk about this when you file. You will need to show evidence of the abuse—a police report, a restraining order, or a declaration from a counselor or advocate. If the court grants your request, you can keep your new name private, which is an important safety measure.

Frequently Asked Questions

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

Yes. A criminal record does not automatically disqualify you from changing your name. However, if you are trying to change your name to evade a court order, hide from law enforcement, or commit fraud, the judge will deny your petition. Be honest with the court about your criminal history if asked.

How long does a name change take from start to finish?

The process typically takes four to six weeks. The main delay is the four-week newspaper publication requirement. Once that is done and you have proof of publication, your hearing can happen within a week or two. After the judge approves your petition, you can start updating your name with other agencies right away.

Do I need to change my name everywhere at once?

No. You can update your name with different agencies and institutions at your own pace. However, it is a good idea to start with Social Security and the DMV, since those are the documents most other places will ask to see. After that, update banks, employers, and insurance companies as you interact with them.

What if the judge denies my petition?

Denials are rare, but they can happen if the judge believes you are changing your name for a fraudulent reason or to evade a court order. If your petition is denied, you can file a new petition after a waiting period (usually six months to a year, depending on the reason for denial). You can also consult with a lawyer about whether to appeal.

Can I change my name back to my old name using the same process?

Yes. Changing your name back follows the exact same court process as any other name change. You file the same forms, pay the same fee, publish the notice, and attend a hearing. There is no special rule against changing your name multiple times, though some judges may ask why you are changing it again.
