The California name change process starts in your county superior court, not with the state

A legal name change in California requires you to file a petition in the superior court of the county where you live, attend a hearing, and get a judge's order. You cannot change your name through the DMV, Social Security, or any state office—the court order is what makes it official. The whole process usually takes four to eight weeks from filing to final order, though it varies by county.

You do not need a lawyer to do this, though you can hire one. The forms are public, the filing fees are set by statute, and the court will tell you exactly what to submit. The main work is filling out the petition correctly, serving notice on anyone required by law, and showing up to your hearing.

Key Takeaways

  • File your petition in the superior court of the county where you live using forms available free from the court clerk or online.
  • You must publish a notice of your petition in a local newspaper for four weeks before your hearing, unless the court waives publication.
  • Serve a copy of your petition on the district attorney and any other required parties at least two weeks before your hearing date.
  • Attend your hearing in person; the judge will ask why you want to change your name and may grant the order the same day if everything is in order.
  • After the judge signs the order, take certified copies to Social Security, the DMV, and your bank to update your records.

What forms you need and where to get them

California courts use a standard petition form called the Petition to Change Name (Form NC-100 in some counties, though the exact name varies). You also need a Declaration Under Penalty of Perjury (Form NC-110) where you state your reasons for the change. Both forms are available free from your county superior court clerk's office, either in person or on the court's website.

Some counties post all the forms you need as a packet. Others require you to ask the clerk which forms explore to your situation—for example, if you have a criminal record, you may need an additional form. Call your county clerk's office or visit the court website before you go in person. Having the right forms saves a trip back.

You will also need to prepare an Order to Change Name (Form NC-120), which is the document the judge will sign if your petition is granted. This form is blank when you file it; the judge fills in the new name and signs it during or after your hearing.

Filing your petition and paying the court fee

Take your completed petition, declaration, and order form to the superior court clerk's office in the county where you live. The clerk will check that the forms are filled out correctly and accept your filing. Court filing fees for a name change petition vary by county but typically range from $200 to $400. Some counties offer fee waivers if you cannot afford to pay; ask the clerk about this when you file.

When you file, the clerk will give you a case number and a hearing date. Write down both. The hearing date is usually four to eight weeks away, which gives you time to complete the publication and service requirements. Ask the clerk which newspaper you must use for publication—it must be a newspaper of general circulation in your county, and the court will tell you which ones may have access to.

Publishing notice in a newspaper and serving the district attorney

Before your hearing, you must publish a notice of your petition in a local newspaper once a week for four consecutive weeks. The newspaper will handle the actual publication; you contact them, provide the notice text (which they can help you write), and pay their publication fee, which is usually $100 to $300 depending on the paper and county. Keep the proof of publication the newspaper gives you—you will need to bring it to your hearing.

You must also serve a copy of your petition on the district attorney of your county at least two weeks before your hearing. "Serve" means delivering a copy by mail or in person. The district attorney's office address is on the court's website or in the phone book. Send it certified mail with return receipt requested, or deliver it in person and get a receipt. Keep proof of service—a stamped copy from the post office or a receipt from the DA's office.

If you have a criminal record, the district attorney may object to your petition. This does not automatically stop the name change, but you should be prepared to explain your reasons to the judge. If you do not have a criminal record, the DA rarely objects.

Attending your hearing and getting the judge's order

On your hearing date, go to the courtroom listed on your case paperwork. Bring the original petition, the proof of publication from the newspaper, and proof that you served the district attorney. Dress neatly and arrive early. The judge will ask you why you want to change your name. Answer honestly and briefly—common reasons are personal preference, marriage or divorce, religious or cultural identity, or professional use. The judge is not looking for a dramatic story; a straightforward answer is fine.

If everything is in order—your forms are correct, you published notice, you served the DA, and the judge sees no reason to deny the change—the judge will sign the order right there or within a few days. You will receive certified copies of the signed order. Order at least five or six certified copies; you will need them to update your name with Social Security, the DMV, banks, and employers.

Updating your name with government agencies and financial institutions

Once you have the signed court order, take certified copies to Social Security first. Go to your local Social Security office with the order and your current ID. Social Security will issue you a new Social Security card with your new name. This usually takes one to two weeks.

Next, go to the DMV with your court order, your new Social Security card, and your current driver's license or ID. The DMV will issue a new license or ID card with your new name. Bring a certified copy of the court order; the DMV keeps it on file.

Update your bank, credit card companies, employer, insurance companies, and any other institution that has your name on file. Most will accept a certified copy of the court order by mail. Some may ask for additional ID. Keep one certified copy for your records and file it somewhere safe—you may need it years later if a question comes up about your legal name.

When you might not need to publish notice

California law allows the court to waive the newspaper publication requirement in certain situations. If you can show good cause—for example, if publishing your name change would put you in danger, or if you are changing your name for a legitimate personal reason and publication would cause undue hardship—you can ask the judge to waive it. To do this, file a Declaration in Support of Waiver of Publication along with your petition, explaining why publication should not be required.

The judge decides whether to grant the waiver. If granted, you skip the newspaper step and move straight to serving the district attorney and attending your hearing. Not all judges grant waivers, so do not count on it unless you have a strong reason. If your petition is denied, you can refile and try again, or you can proceed with publication as originally required.

Frequently Asked Questions

Do I need a lawyer to change my name in California?

No. The forms are public and the process is straightforward enough that most people handle it themselves. A lawyer can help if you are unsure about any step or if you have a criminal record and expect the district attorney to object, but it is not required.

Can I change my child's name?

Yes, but the process is different. You file a petition on behalf of your minor child, and both parents must consent unless one parent's parental rights have been terminated. If the other parent does not consent, you will need to prove it is in the child's best interest. The court clerk can tell you which additional forms you need.

What if I have a criminal record?

A criminal record does not automatically prevent a name change, but the district attorney may object. The judge will consider whether the change is for a legitimate purpose or to evade criminal liability. If your reason is genuine—personal preference, religious identity, professional use—you can still succeed even with a record. Be honest with the judge about your past.

How long does the whole process take?

From filing to receiving your signed order usually takes four to eight weeks. The main delay is the four-week publication period in the newspaper. After you get the order, updating your name with Social Security and the DMV takes another one to two weeks.

Can I change my name back if I change my mind?

Yes. You file another petition using the same process. There is no waiting period between a name change and changing it again, though the court may ask why you are changing it so soon. The filing fee applies each time.
