Name Change after Divorce in California

Your name is one of the most personal things you carry into a marriage — and one of the first things people reassess when a marriage ends. Whether you're ready to reclaim a name that feels like "you" again, or you want a fresh start entirely, you have clear legal options in California. According to a 2023 Pew Research Center survey, about 79% of women in opposite-sex marriages took their spouse's last name, which means a lot of people face this exact question when divorce enters the picture. This guide walks you through every path available, from the simplest checkbox on your divorce paperwork to a full court petition for a brand-new name.

3 ways to change your name after a California divorce

Your name is part of your legal identity, and California gives you real flexibility in changing it. The right path depends on whether you want to return to a name you've used before or step into something completely new.

Here are the three options available to you:

• Change your name as part of your divorce case. If you want to return to a former legal name, such as your name before marriage, you can request this directly on your divorce paperwork before the judge signs off. It's the simplest and most cost-effective path.
• Change your name after your divorce is final. If you didn't request the change during your divorce, you can still revert to a former legal name by filing one additional form with the court that handled your case. There's no deadline, and you can do this months or years later.
• File a separate court petition for a new name. If you want a name you've never legally held before, the process is separate from your divorce entirely. It involves filing a petition, publishing a public notice, attending a hearing, and receiving a court order.

The first two options only work if you're returning to a name you previously held. The third option is the route to take when you want something new.

How to request a name change during your divorce

The easiest time to change your name is while your divorce is still active. Two standard California divorce forms include spaces specifically for this request, and you won't need separate filings or additional fees beyond what you're already paying.

The two forms where name change requests appear are:

• Declaration for Default or Uncontested Dissolution or Legal Separation (form FL-170). Item 12 on this form lets you indicate a return to a former legal name.
• Judgment (form FL-180). Item 4(f) is where you write in the full first, middle, and last name you want restored. Once the judge signs this form, it becomes your legal proof of the name change.

After the judge signs your Judgment, request certified copies from the court clerk. You'll need them when updating your records with agencies like the Social Security Administration and the California DMV. Certified copies currently cost $40 each, so order a few at once to save yourself return trips.

If you're the responding spouse rather than the petitioner, you can also request a name change on your Response (form FL-120, item 11b). Either party in the divorce can make this request.

How to finalize your name change after the divorce

If your divorce is already final and the Judgment didn't include a name change order, you still have a straightforward option. Form FL-395, the Ex Parte Application for Restoration of Former Name After Entry of Judgment, lets you go back to the court that handled your divorce and request restoration of a former legal name at any time. There is no deadline.

Here's how the process works:

1. 1
   Gather your divorce paperwork. You'll need your case number and the county where your divorce was filed. If you've moved since your divorce, you still file with the original court.
2. 2
   Complete form FL-395. Fill in your case information exactly as it appears on your divorce documents, including the full name you want restored. Make one copy for your records.
3. 3
   File the form with the original court. You can do this in person or by mail. Include a self-addressed stamped envelope if filing by mail so the court can return your signed order. Processing typically takes two to four weeks.
4. 4
   Pay the applicable fee (if any). If you paid your divorce filing fees in full, there may be no additional charge. If fees were waived during the divorce, a filing fee of $435 to $450 may apply. Ask the clerk before filing.
5. 5
   Request certified copies. Once the judge signs your FL-395, request certified copies from the clerk. The current fee is $40 per copy. You'll need these to update your IDs and records.

The FL-395 process is considerably simpler than filing a new name change petition. It doesn't require publishing a public notice or attending a court hearing. For most people returning to a former name, this is the most practical route after a divorce is finalized.

How to change your name to something new

If you want a name you've never legally used, that path runs through a separate court process, independent of your divorce. California's self-help court resources describe the timeline as roughly three months from start to finish, though that can vary by county.

The process requires these forms:

• Petition for Change of Name (form NC-100). This is your formal request to the court.
• Attachment to Petition for Change of Name (form NC-110). Required in most counties.
• Order to Show Cause for Change of Name (form NC-120). Sets the hearing date and triggers the publication requirement.
• Civil Case Cover Sheet (form CM-010). Required by some courts but not all.
• Decree Changing Name (form NC-130). Complete the top portion and Item 3. The judge signs this at your hearing to finalize the change.

Filing fees run $435 to $450. If cost is a barrier, ask the court clerk about a fee waiver — you may qualify. After filing, you'll publish notice of your petition in a local newspaper once a week for at least four weeks before your hearing. This public notice requirement gives anyone with a legal interest in the matter an opportunity to respond.

At the end of your hearing, the judge issues a Decree Changing Name. That signed decree is your legal proof of the change. Order certified copies at $40 each, because you'll need them to update your Social Security card, driver's license, passport, and other records.

What does a name change cost in California?

The cheapest route, when possible, is to request your former legal name as part of your divorce before the Judgment is signed. You're already in the court system, paying filing fees, and the name request requires only filling in a few lines on forms you're completing anyway.

If you've missed that window, the FL-395 route is the next most affordable option. Publication is not required, and there's no hearing. The only variable is whether your court assesses an ex parte filing fee, which depends on the county and whether your original divorce fees were waived.

A brand-new name petition carries the most cost and time. Factor in the filing fee, publication costs (which vary by newspaper and county), and your time attending a hearing. Budget accordingly and check with your county superior court for their specific fee schedule.

What to update after your name change

Once you have a signed court order or Judgment reflecting your new name, you'll need to notify several agencies before your legal identity is fully updated. Start with Social Security, because most other agencies verify against SSA records. Do not update your passport or financial accounts until your SSA and DMV records reflect the change.

1. U.S. Social Security Administration

Complete an Application for a Social Security Card (form SS-5) and bring it to your nearest SSA office with certified copies of your court order and current ID. Your updated card should arrive within a few weeks. Updating Social Security first makes the rest of the process smoother because many agencies check SSA records to verify a name change.

2. California Department of Motor Vehicles

Visit a DMV field office with your updated Social Security card (or SSA receipt), your current driver's license, and certified copies of your court order. You'll need a new driver's license or state ID to reflect your updated name. Starting May 7, 2025, REAL ID compliance is required for domestic air travel, so confirm your updated license meets that standard when you visit.

3. California Department of Public Health (birth certificate)

To update your birth certificate, complete form VS 23 and attach a certified copy of your court order. Mail the documents along with a $23 fee to California Department of Public Health, Vital Records, M.S. 5103, P.O. Box 997410, Sacramento, CA 95899-7410.

4. U.S. Passport

If you have a valid passport, submit form DS-5504 (within one year of issuance) or DS-82 (for passports issued more than one year ago) along with your current passport and a certified copy of your name change order. Update your passport before international travel, since the name on your passport must match your boarding pass exactly.

5. Financial accounts, insurance, and employer records

After updating your Social Security and DMV records, notify your bank, credit card issuers, insurance providers, mortgage servicer, and employer. Most will require a certified copy of your court order.
