No, you do not have to take your husband’s last name. No state law and no federal law requires it, and the same is true in reverse: your husband is not required to take yours, and partners in a same-sex marriage have the same freedom. Keeping your birth name takes no paperwork, no filing, and no court approval. If you want to change your name, your marriage certificate is the legal tool that lets you do it, but nothing updates automatically. You have to walk the change through each agency yourself, in the right order.
There is also no deadline. You can change your name the week after the wedding or ten years later. Until you take affirmative steps, every record you have, from your Social Security card to your passport, stays in your birth name.
What Your Options Actually Are
People often think of this as a yes-or-no decision. It isn’t. Through the marriage certificate alone, in every state, you can:
- Keep your birth name. Nothing to file, nothing to explain.
- Take your spouse’s surname.
- Hyphenate both surnames, such as Carter-Williams.
- Move your birth surname to your middle name and take your spouse’s surname as your last. Most states allow this directly on the marriage certificate.
- Have your spouse take your name instead. The process is identical.
The option that usually requires more than a marriage certificate is a true blended surname, where you merge parts of both names into something new (combining “Anderson” and “Martinez” into “Andertinez,” say). Only a handful of states, including California, Kansas, New York, and North Dakota, explicitly permit surname blending on the marriage license. A few others, including Iowa, Massachusetts, and Minnesota, allow couples to adopt any surname at marriage, which effectively covers blending. Everywhere else, a blended surname means filing a separate name-change petition in court. Court filing fees typically run between $150 and $500, and some courts also require you to publish a notice in a local newspaper. If a blended name matters to you, read your state’s marriage license application before the wedding; some forms list the available surname options directly.
If You Keep Your Birth Name
You are done. There is no form to file, no agency to notify, and no document to update. Your Social Security card, driver’s license, passport, bank accounts, deeds, and tax records all stay exactly as they are. Being married doesn’t require any of them to reflect a different name.
One practical note: you will encounter forms and clerks who assume you took your husband’s name. That assumption has no legal weight. Correct it when it comes up and move on.
If You Do Want to Change Your Name
Start by ordering certified copies of your marriage certificate from the county clerk or vital records office where you married. Fees generally fall between $10 and $25 per copy. Order at least two or three. Some agencies want originals, and having extras keeps you from waiting on one agency before you can start with the next.
You will also need a current government-issued photo ID, such as a passport or driver’s license, and your Social Security number. If you apply through the Social Security Administration’s paper process, you will fill out Form SS-5, which asks for your place of birth, citizenship status, and both parents’ full names.1Social Security Administration.

Social Security Comes First
The Social Security Administration has to be your first stop. Other agencies, including state motor vehicle offices, verify your identity against SSA records, so nothing else moves forward cleanly until this update is done.2USAGov. How to Change Your Name and What Government Agencies to Notify
In some states, you can handle the change online through a personal my Social Security account.3Social Security Administration. How Do I Change or Correct My Name on My Social Security Number Card Where the online option isn’t available, complete Form SS-5 and submit it with your certified marriage certificate and a valid photo ID, either by mail or in person at a local SSA office. If you’d rather not mail original documents, go in person. Acceptable proof of identity includes a U.S. driver’s license, state-issued ID card, or U.S. passport.4Social Security Administration. Learn What Documents You Will Need to Get a Social Security Card Your Social Security number itself doesn’t change; only the name on it does. The SSA estimates 7 to 10 business days to issue the new card once it has everything it needs, though mail-in applications can take longer.5Social Security Administration.

Driver’s License or State ID
Once SSA records show your new name, go to your state’s motor vehicle office with your new Social Security card, your certified marriage certificate, and your current license. Most states require an in-person visit for a new photo and signature. Replacement fees typically run $10 to $40. An updated license makes every later step easier, because it is the ID you will be asked for most often.
Passport
Which form you use depends on timing. If your name changed less than a year ago and your passport was issued less than a year ago, submit Form DS-5504 by mail with your current passport, a certified marriage certificate, and a new photo. There is no application fee for this route, though expedited service costs an additional $60.6U.S. Department of State. Change or Correct a Passport
If more than a year has passed since either your passport was issued or your name was legally changed, you will renew instead, using Form DS-82 by mail or Form DS-11 in person. The standard adult passport book fee is $130.7U.S. Department of State. Passport Fees If you have international travel booked, move this one up the list. A mismatch between the name on your ticket and the name in your passport can cause problems at the airport.
Taxes and Your Employer
The IRS matches the name and Social Security number on every return against SSA records. If they don’t match, your refund can be delayed. The rule is straightforward: if you’ve already updated your name with the SSA, file under your new name. If you haven’t, file under your former name, the one SSA still has on file.8Internal Revenue Service. Name Changes and Social Security Number Matching Issues
After your SSA record is updated, tell your employer so they can update your W-4 and issue future W-2s correctly. If you receive a W-2 in your old name after the SSA change, ask for a corrected W-2c and include it with your return.8Internal Revenue Service. Name Changes and Social Security Number Matching Issues
Voter Registration
Update your voter registration too. Most states let you do this online, by mail, or in person at a local election office. Vote.gov will route you to your state’s process and deadlines.9USAGov. How to Update or Change Your Voter Registration A mismatch between your registration and your ID can mean a provisional ballot on Election Day, so don’t let this one slip.
Banks, Credit, and Property
Each bank, credit card issuer, and investment firm has its own process, but they all ask for the same combination: a certified marriage certificate and a government-issued ID that matches. Start with your primary bank and work outward. Your credit history and score carry with you; a name change doesn’t reset anything or open a separate credit file.
For a house you own, the deed and the mortgage are separate. Updating a deed typically means filing a quitclaim deed with your county clerk, and some states want it notarized or prepared by an attorney. Your mortgage lender can tell you what they need, which is usually a written request with supporting documents. If you hold a professional license, check with the issuing board early, because practicing under a name that doesn’t match your license can create compliance problems.
Why the Order Matters
The most common mistake is trying to update everything at once. Agencies verify against each other, which creates a chain: Social Security first, driver’s license next, then passport, taxes, voter registration, and the rest. Jumping ahead, such as applying for a new passport before SSA shows your new name, leads to rejections and extra fees. Work through the list in order, keep a stack of certified marriage certificates within reach, and most people finish inside a few weeks.
