To legally change your last name in the United States, you file a petition with the civil court in the county where you live, pay a filing fee of roughly $150 to $500, publish notice in a local newspaper if your state requires it, and attend a short hearing where a judge signs the decree. The whole process usually takes one to three months. If your name change is tied to marriage, divorce, or naturalization, you can skip the standalone petition and handle it inside paperwork you’re already filing.
Shortcuts Through Marriage, Divorce, or Naturalization
Three life events let you avoid a separate court petition. Each one folds the name change into an existing legal process, which saves both time and money.
Marriage
Marriage is the most common trigger. When you apply for a marriage license, list the new last name you want on the application itself. After the ceremony, your marriage certificate is the legal document proving the change, and you use it to update your Social Security card, driver’s license, and other records without going to court. The catch: you have to put the new name on the marriage license application before the wedding. Skip that step and you’ll need a separate court petition later.
Most states limit the options on the marriage license to your spouse’s surname, your current surname, a hyphenated combination, or a rearrangement of both existing names. Only a handful of states allow “surname blending,” where you combine parts of both names into a new surname on the license itself. If you want a blended or entirely new name that doesn’t fit your state’s options, you’ll need a court petition.
Divorce
A divorce decree can restore your maiden name or any prior legal surname. You request it as part of the final divorce paperwork, and the judge writes it into the signed decree. There’s usually no additional filing fee. If your divorce is already final and you didn’t request the change at the time, some states let you reopen the case to add it; others require a fresh petition.
Naturalization
If you’re becoming a U.S. citizen, you can request a name change directly on Form N-400, the Application for Naturalization. The change becomes official at the oath ceremony when a judge approves it, and your new name appears on your Certificate of Naturalization. USCIS will also notify the Social Security Administration on your behalf.1U.S. Citizenship and Immigration Services. Form N-400, Instructions for Application for Naturalization
Filing a Court Petition
If none of those shortcuts apply, file a formal petition with the civil court in the county where you live. This is the route for personal, religious, professional, or gender-identity-related reasons.
The standard forms are a Petition for Change of Name and a proposed Decree or Order. Your court clerk’s office or the court’s self-help website will have the specific forms for your jurisdiction. They ask for your current legal name, the exact new name you want, your date of birth, address, and the reason for the change. Double-check the spelling of the new name before you sign. Errors on the decree cause real problems with federal agencies later.
Most courts also require you to disclose your criminal history. In many states that means specifically addressing whether you’re a registered sex offender, on parole or probation, or have pending criminal charges. Some jurisdictions require a fingerprint-based background check. You sign under penalty of perjury, so accuracy matters.
What It Costs
Filing fees vary widely but generally fall between $150 and $500. On top of that, expect:
- Newspaper publication: often $30 to $200 or more, depending on the paper and how many weeks of publication your state requires.
- Certified copies of the decree: typically $5 to $25 per copy. Order several.
If you can’t afford the filing fee, ask the court for a fee waiver. Courts routinely grant these for petitioners who meet income guidelines, and the clerk’s office will have the application.
Publication and the Hearing
After the court accepts your filing, most states require you to publish a notice of your intended name change in a local newspaper. Schedules vary. Some states require a once-a-week notice for several consecutive weeks; others require just one publication. The notice gives creditors and other interested parties a window to object. Not every state requires publication, and judges in many states can waive it for good cause, particularly for domestic violence survivors or when publication would create a safety risk.
Once the publication period ends, you file proof of publication with the court. The clerk will have already scheduled a hearing date when you filed. At the hearing, a judge reviews your paperwork, confirms publication was met, and asks whether anyone filed an objection. Most name change hearings are brief and uncontested. If everything checks out, the judge signs a decree making the change official.
Order several certified copies of the decree before you leave the courthouse. You’ll need separate certified copies for the Social Security Administration, the DMV, your passport application, your bank, and possibly your employer and licensing boards. Ordering them all at once from the clerk is cheaper and faster than going back later.
When a Judge Can Deny Your Petition
Judges have discretion to deny a name change. The most common reasons are intent to defraud creditors, evade debts, or mislead others. If you have pending criminal charges, most courts will delay or deny the petition until the case is resolved. Registered sex offenders face additional hurdles in many states, ranging from outright prohibitions to notification requirements for law enforcement.
In several states, a felony conviction creates a presumption of bad faith. The burden shifts to you to prove by clear and convincing evidence that the request is legitimate, made in good faith, and won’t compromise public safety. That doesn’t make a name change impossible, but it means you’ll likely need a more detailed explanation and possibly a lawyer.
Safety-Based Confidential Name Changes
Survivors of domestic violence, stalking, sexual assault, and human trafficking face an obvious problem: a published newspaper notice announcing a new name defeats the whole point. Most states let the court waive the publication requirement and seal the name change records when the petitioner shows a safety concern. In many states, good cause for waiving publication is presumed if the petitioner states they are a victim of domestic violence or a similar crime; no arrest or prosecution of the abuser is required.
Many states also run an Address Confidentiality Program (sometimes called “Safe at Home”) that gives participants a substitute address for public records. Enrollment can support both the publication waiver and record sealing. One limitation: even with sealed court records, the Social Security Administration links your old and new names internally, and federal and state agencies may still be able to connect the two identities. A confidential name change adds a real layer of protection from an abuser searching public records, but it doesn’t create an untraceable new identity.
Changing a Minor Child’s Last Name
Changing a child’s last name follows the same petition process with one added layer: parental consent. Most states require the written, notarized consent of both living parents who haven’t abandoned the child. If one parent consents and the other doesn’t, you’ll need to formally serve the non-consenting parent with notice of the hearing, usually by certified mail. That parent then has an opportunity to appear and object.
If a parent’s whereabouts are unknown, courts have procedures for alternative service, such as publication. If a parent has abandoned the child (often defined as six months or more without meaningful contact or financial support), the court may waive the consent requirement, but the petitioner typically bears the burden of proving abandonment. Judges evaluate a child’s name change under a best-interest standard, which makes contested cases harder to predict than adult petitions.
Updating Your Records After the Decree
The court decree is the halfway point. It doesn’t automatically update anything. You contact each agency individually, and the order matters.
Social Security Administration First
Start here. Almost every other agency verifies your identity against Social Security records, so updating the SSA first prevents mismatches that delay everything else. You can begin online at ssa.gov, though you may need to visit a local office in person depending on your situation.2Social Security Administration. Change Name with Social Security You’ll need your certified court decree (or marriage certificate or divorce decree), proof of identity such as a driver’s license, and proof of citizenship such as a U.S. birth certificate or passport. The SSA requires original documents or copies certified by the issuing agency. Photocopies and notarized copies won’t be accepted.3Social Security Administration. U.S. Citizen – Adult Name Change on Social Security Card There is no fee for a new Social Security card.
Driver’s License or State ID
Once your Social Security record is updated, visit your state’s DMV or equivalent agency. Bring the updated Social Security card and your certified court decree. The DMV verifies your information against the SSA database. If they don’t match, your application will be denied until they do. Some states require proof of every prior legal name change you’ve had, so bring any earlier marriage certificates or court orders as well.
U.S. Passport
Which form you use depends on timing. If both your passport was issued and your name was legally changed within the past year, submit Form DS-5504 by mail with your current passport, a certified name change document, and a new photo. If more than a year has passed since either event, you can renew by mail using Form DS-82 (if your passport was issued when you were 16 or older, within the last 15 years, and is undamaged) or apply in person with Form DS-11.4U.S. Department of State.

Voter Registration
Update your voter registration to reflect your new name. The process varies by state. Some let you update online; others require a mailed form or an in-person visit to your local election office. Go to vote.gov and select your state for specific instructions and deadlines.5USAGov. How to Update or Change Your Voter Registration Don’t wait until election season, because a missed registration deadline can keep you from voting under your new name.
IRS and Employer
The IRS doesn’t need a separate notification. It pulls your name from the Social Security database. But your name on your tax return has to match what the SSA has on file, or the IRS may delay processing your refund. If you changed your name partway through the year, file under the name that matches your current Social Security card. If your employer issued a W-2 under your old name, ask them to correct it. You can also correct the name on the copies of the W-2 you file with your return.6Internal Revenue Service. Name Changes and Social Security Number Matching Issues Notify your employer promptly so payroll and withholding records line up going forward.
Professional Licenses and Private Accounts
If you hold professional licenses in nursing, law, real estate, teaching, or any other regulated field, contact each licensing board to update your name. Most boards require a completed name change request form and a copy of the court decree or marriage certificate. Banks, credit card companies, insurance providers, and investment accounts each want to see the certified decree or marriage certificate as well. There’s no single form or shortcut for private institutions. Expect to contact each one individually with your documentation.
