No. A woman does not have to change her last name when she gets married anywhere in the United States. There is no federal or state law that requires it. Your legal name stays exactly what it was on your birth certificate unless you take active steps to change it. Marriage only makes a name change easier if you want one, because your marriage certificate can stand in for the court petition that would otherwise be required.
The Choices You Actually Have
The decision is not a binary between keeping your name and taking your spouse’s. Several options are open to you, and most can be done using the marriage certificate alone.
- Keep your birth name. Do nothing. No paperwork, no notifications, no updates. Your legal name is unchanged.
- Take your spouse’s surname. The traditional route. Your marriage certificate is the legal document that authorizes the change with government agencies.
- Hyphenate. Combine both surnames with a hyphen, like Martinez-Chen. Most states allow this through the marriage certificate alone.
- Use both surnames without a hyphen. Some people carry two last names, using one professionally and the other socially. How your state handles this on the marriage license varies.
- Move your birth surname to your middle name. Sarah Marie Johnson becomes Sarah Johnson Lee. You keep your birth name as part of your legal identity while taking your spouse’s surname.
- Create an entirely new surname together. Both spouses adopt a brand-new last name. This usually needs a court petition rather than just a marriage certificate.1USAGov. How to Change Your Name and What Government Agencies to Notify
There is also no deadline. If you want to keep your maiden name for now and change it in five years, you can. If you want to change it a week after the wedding, you can. If you never want to change it, that is also fine.
Can a Husband Take His Wife’s Last Name
Yes, but the process is not as smooth. Only about a third of states allow a man to use the marriage certificate alone to take his wife’s surname. In the rest, a husband who wants his wife’s last name has to go through the formal court name-change process: a petition, a filing fee, and sometimes a court hearing. Same-sex couples run into similar patchwork rules depending on the state.
What Changes If You Do Decide to Change It
If you choose to change your name, the mechanics matter, because doing things out of order creates problems. The marriage certificate is your foundation document, and Social Security is your first stop.
Order Certified Copies of Your Marriage Certificate
Request several certified copies from the county clerk or vital records office where your marriage license was filed. Three to five is a reasonable starting number, because several agencies want them at the same time and some do not return them quickly. Certified copies generally run between $9 and $35 depending on the county. A photocopy will not do. Agencies want the version bearing an official seal or stamp from the issuing office.1USAGov.

Social Security First, Always
Every other agency verifies your name against Social Security records. If you go to the DMV or the passport office before updating Social Security, you will be turned away.
In some states you can request a new Social Security card entirely online through a personal my Social Security account. Otherwise you can start online and finish at a local office, or complete a paper Form SS-5 and bring it in with your marriage certificate and proof of identity such as a driver’s license or passport.2Social Security Administration. How Do I Change or Correct My Name on My Social Security Number Card SSA needs originals or certified documents, not photocopies. The new card typically arrives within 7 to 14 business days, and there is no fee.3Social Security Administration. Application for Social Security Card
Driver’s License
Once Social Security is updated, go to your state’s motor vehicle agency. Most states require an in-person visit. Bring your new Social Security card or the receipt showing you applied, your current license, and a certified copy of your marriage certificate. Replacement fees generally run between $11 and $37. Some states impose a deadline for updating your license after a legal name change, often 10 to 30 days, so this is not a step to leave sitting for months.
Passport
If your passport was issued less than a year ago and your name change also happened within that year, you can use Form DS-5504, which is free unless you pay for expedited processing.4U.S. Department of State. Change or Correct a Passport Beyond that window, you renew using Form DS-82 by mail or Form DS-11 in person, at the standard renewal fee.5U.S. Department of State. United States Passport Fees Routine processing takes four to six weeks. If you have international travel coming up, this is the step that catches people out.
Taxes, Voting, and Travel in the In-Between
The stretch between the wedding and the moment every document reflects your new name is where quiet problems appear.
The IRS matches the name and Social Security number on your tax return against SSA records. File under a name SSA does not yet have on file and your refund can be delayed. The rule is simple: use whatever name Social Security currently has. If you married in December but have not updated SSA before filing, file under your maiden name. If SSA already shows the new name, use the new name.6Internal Revenue Service. Name Changes and Social Security Number Matching Issues
Voter registration works the same way. If you change your legal name, update your registration. A mismatch between your registration and your ID can lead to delays or a provisional ballot. You can start at vote.gov, which routes you to your state’s system.7USAGov. How to Update or Change Your Voter Registration
Travel is the other pinch point. The name on your airline reservation needs to match the ID you show at security. Book under whatever name is on the ID you plan to use at the airport. If you already booked under a name that no longer matches, most airlines will change it for free with documentation of the legal name change. Trusted Traveler memberships like Global Entry and TSA PreCheck need their own update through CBP customer support, and may require an in-person visit to an enrollment center.8Department of Homeland Security.

Credit and Everything Else
Your credit history does not migrate automatically. Old accounts under your maiden name will not silently reattach to a file under your married name, and your credit history can effectively disappear if you do not tell your creditors to update. Contact your banks, credit card issuers, and loan servicers directly. After a billing cycle or two, pull your credit reports to confirm the full history now sits under the new name. You can get free annual reports from all three bureaus at annualcreditreport.com.
A handful of other updates finish the picture:
- Employer and payroll, so your W-2 and W-4 reflect your legal name.
- Health insurance, to avoid claim denials over name mismatches.
- Property records with your county tax office and mortgage servicer if you own a home.1USAGov. How to Change Your Name and What Government Agencies to Notify
- Professional licenses through your state licensing board, which usually charges a fee and wants a copy of the marriage certificate.
- Estate planning documents, including your will, power of attorney, and beneficiary designations on retirement accounts and life insurance.
- Utilities and subscriptions, which are lower priority but worth cleaning up eventually.
Most institutions will want a certified copy of the marriage certificate and a current government ID showing your new name. Keeping both on hand before you start making calls saves repeat trips. And none of it is required. The whole apparatus only turns on if you decide, on your own timeline, that you want it to.
