To hyphenate your last name, you either use the name-change built into a marriage license or divorce decree, or you file a name-change petition with the court in the county where you live. Both routes end with a legal document — a marriage certificate, divorce decree, or court order — that you then use to update your Social Security card, passport, driver’s license, and every account tied to your old name.
Which Legal Route Applies to You
Most people hyphenating a surname are doing it around a marriage or a divorce, and in those situations a separate court petition is usually unnecessary. When you apply for a marriage license, many states ask you to declare the name you’ll use after the wedding. Write your hyphenated name on that application and your marriage certificate becomes the legal proof of the new name.
Timing matters. If your state collects the new name on the license application, you need to decide before the wedding, not after. If you miss that window or your state doesn’t offer the option, you’ll be looking at a court petition instead.
Divorce works the same way. Request the hyphenation or restoration as part of the divorce proceedings, and the decree carries the name change. If the decree is silent on the name, you’ll need a separate court petition afterward.
Anyone hyphenating outside of a marital event — for cultural identity, personal preference, or any other reason — goes through the court petition process from the start.1USAGov. How to Change Your Name and What Government Agencies to Notify
Filing a Court Petition
The petition is filed with the court in the county where you live, and it lists your current name, your desired hyphenated name, and your reason for the change. You submit it with proof of identity and a non-refundable filing fee.
Fees vary widely. Some counties charge as little as $25; others run up to $500. Many courts offer fee waivers if you can show financial hardship. Keep copies of everything you file, including the payment receipt.
Some jurisdictions require a background check, and roughly half of all states require you to publish a notice of the name change in a local newspaper before the court will approve it. Publication adds both cost and time. Call your court clerk’s office before filing so you know exactly what your county requires.1USAGov. How to Change Your Name and What Government Agencies to Notify
Whether You’ll Have a Hearing
Not every county holds a hearing for a straightforward name change. Some judges review the paperwork and sign off without an appearance. Others schedule a hearing weeks or months after filing, depending on the backlog.
If you do have to appear, the judge’s job is to confirm the change isn’t meant to dodge debts or a criminal record. For a hyphenation, the exchange is usually brief. Bring your court order paperwork, photo ID, and any supporting documents such as a marriage certificate. If someone files an objection, the judge will hear both sides before ruling.
Update Social Security First
However your name change became legal, the Social Security Administration is your first stop. Other agencies and private institutions pull name data from SSA records, and updating there first prevents mismatches down the line.
Depending on your situation you may be able to request the change online. Otherwise you’ll make an appointment at a local Social Security office.2Social Security Administration.

Update Your Passport
The passport process depends on how recently your passport was issued relative to when your name changed. If both happened within the past year, submit Form DS-5504 by mail with your current passport, a passport photo, and your name-change document. There’s no fee unless you pay for expedited processing.
If more than a year has passed on either front, you renew instead — Form DS-82 by mail or Form DS-11 in person — with your current passport, name-change document, a new photo, and the applicable renewal fees. A marriage certificate, divorce decree, or court order all qualify as proof.4U.S. Department of State. Change or Correct a Passport
Update Your Driver’s License
Take your court order or marriage certificate and your current license to your state’s motor vehicle office. Many states require your Social Security record to be updated first, so don’t try to jump the sequence. Once you have an updated license or state ID, most other institutions will accept it as primary identification, which makes every remaining update easier.1USAGov.

Banks, Credit Cards, and Your Credit Report
Contact your bank, credit card issuers, mortgage lender, and insurance providers to update your name. Most want a copy of your name-change document and a current photo ID. Don’t skip investment accounts, retirement accounts, and student loan servicers.
You generally do not need to contact the credit bureaus directly. Once your creditors report the new name, the bureaus link it to your existing credit file using your Social Security number. Your previous name stays on the report as a former name, and no new file is created. Your score and history carry over intact. The real risk is letting accounts sit with mismatched names long enough to cause confusion during a loan application or credit check.
Employer and Tax Records
Tell your employer promptly. They should update your Form I-9 by entering your new legal name in the Supplement B fields, and they may ask to see your marriage certificate or court order.5U.S. Citizenship and Immigration Services. Recording Changes of Name and Other Identity Information for Current Employees If your employer uses E-Verify, updating with the SSA first is especially important to avoid a mismatch.
For taxes, the name on your return must match what the SSA has on file. If you’ve already updated your Social Security card, file under your new hyphenated name. If SSA hasn’t processed the change yet, file under your former name to keep the return from being delayed or rejected.6Internal Revenue Service. Name Changes and Social Security Number Matching Issues This trips people up regularly: they file under the new name before SSA has caught up, and the return bounces back.
Wills, Deeds, and Other Paperwork
Update your will, any trusts, powers of attorney, and insurance beneficiary designations to reflect the hyphenated name. Leases and employment agreements should be amended too, though most landlords and employers will handle it informally once you show proof.
If you own real estate, updating the name on the title typically means filing a new deed (often a quitclaim deed) with your county recorder’s office along with your name-change documentation. Recording fees generally run $50 to $200. It’s easy to forget because nobody checks your title day to day, but a mismatch between your legal name and the name on a deed can create complications when you try to sell or refinance.
Changing a Child’s Last Name Is Separate
Hyphenating a minor child’s surname is not the same process as changing your own, and it’s often more involved. You’ll generally file a petition on the child’s behalf, and most courts require both parents’ consent. If one parent objects, the court weighs the child’s best interests before ruling. Requirements and fees vary by jurisdiction, but expect a formal court process even if your own name change happened automatically through marriage.
