You can change your last name after marriage, but the process depends on where you live and whether you want to use your spouse's name, keep your own, or choose something different
Most states allow you to change your name as part of the marriage process or afterward. The simplest route is to change it when you get your marriage license and certificate — many states let you do this without a separate court order. If you did not change it then, or if you want to change it later, you can file a petition in your local court. The exact steps, fees, and waiting periods vary by state and sometimes by county.
You do not have to take your spouse's last name. You can keep your own name, hyphenate both names, combine them in a different order, or choose an entirely new name. The legal process is the same regardless of which option you pick.

Changing your name at the time of marriage
When you explore for a marriage license, most states give you the option to indicate what last name you want on your marriage certificate. Some states call this a "name election" or "name selection" box on the license process. If you mark that you want to change your name, the marriage certificate itself serves as your legal name change document — you do not need a separate court order.
However, the rules differ by state. Some states require you to specify your new name before the license is issued. Others let you decide at the time you pick up the certificate after the ceremony. A few states do not offer this option at all and require you to go through the court petition process if you want to change your name.
Contact your county clerk's office or the vital records office in the state where you are getting married. They can tell you exactly what form to fill out and whether the name change happens automatically or requires an extra step.
Changing your name after marriage through the court
If you did not change your name when you married, or if you want to change it years later, you can file a petition in your local district court or circuit court (the name varies by state). You will need to fill out a petition form, pay a filing fee, and in some cases attend a brief hearing.
The petition form usually asks for your current legal name, the name you want, and your reason for the change. "Marriage" or "personal preference" are both acceptable reasons. Some states require you to publish a notice of your name change in a local newspaper for a set period — typically two to four weeks — to give creditors or others a chance to object. Other states have dropped this requirement or only use it in certain situations.
Filing fees range from about $100 to $500 depending on your state and county. Processing time is usually four to twelve weeks, though it can be longer if the court is backlogged or if you need a hearing. Once the judge signs the order, you receive a certified copy of the name change decree, which you then use to update your other documents.
What documents you need to update after the name change is approved
A court order or marriage certificate that shows your new name is not automatically shared with other agencies. You have to update each document yourself. Start with your Social Security card — this is the most important one because many other agencies use your Social Security number to verify your identity.
Go to your local Social Security office or mail in an process with your certified name change document and a photo ID. Processing usually takes one to two weeks. Once your Social Security record is updated, update your driver's license or state ID at your state's DMV. You will need to bring your Social Security card (or a letter from Social Security showing the change), your certified name change document, and proof of residence.
After that, update your passport through the State Department if you have one, your bank accounts and credit cards by contacting each institution, your employer for payroll and tax records, your insurance policies (auto, home, health), and your voter registration through your local election office. Some of these can be done online or by phone; others require you to mail in documents.
Changing your name if you are not taking your spouse's name
You have the legal right to keep your own last name after marriage in all fifty states. You do not need to provide a reason or file any paperwork — straightforward do not change it. Your marriage certificate will show your current legal name.
If you want to hyphenate your names, combine them in a different order, or choose a completely new name, the process is the same as changing to your spouse's name. You either select the new name on your marriage license process (if your state offers that option) or file a court petition afterward. The court does not care which name you choose — it only verifies that you are making the change for a lawful reason, which includes personal preference.
State-by-state differences in name change rules
The specifics of name change law vary significantly by state. Some states allow name changes on the marriage license process with no additional steps. Others require a separate court petition even if you want to change your name at the time of marriage. A few states have waiting periods before the name change becomes final, and some require newspaper publication while others do not.
Your county clerk's office or your state's vital records agency can tell you the exact process for your location. Many states also post their name change procedures online, though the information is sometimes buried in the vital records or court system website. If you cannot find it, call the clerk's office directly — they handle these requests constantly and can walk you through the steps in five minutes.
Costs and timeline for a court-ordered name change
If you file a petition in court, expect to pay a filing fee between $100 and $500, depending on your state and county. Some counties charge less for name changes related to marriage than for other types of name changes. A few states waive or reduce the fee if you cannot afford it — ask the clerk's office about fee waivers when you file.
The timeline depends on how busy your court is. In many places, a straightforward name change petition is approved within four to eight weeks. If the court requires a hearing or if there are any objections, it can take longer. Some courts process these petitions faster than others, so call ahead to ask what the typical wait is in your county.
Frequently Asked Questions
Do I have to change my name when I get married?
No. You can keep your own last name, hyphenate, or choose any other name. Marriage does not automatically change your legal name in any state — you have to take an active step to change it, whether that is marking a box on your marriage license or filing a court petition.
Can I change my name years after getting married?
Yes. There is no time limit on when you can change your name after marriage. You file a petition in your local court, pay the filing fee, and follow the same process as anyone else changing their name. The court does not care how long you waited.
What if my spouse and I want to choose a completely new last name together?
You can both do this. Either select the new name on your marriage license process (if your state allows it) or file separate court petitions after the marriage. The process is identical to changing to your spouse's name — the court approves whatever name you choose as long as it is for a lawful reason.
Do I need a lawyer to change my name after marriage?
No. The petition process is straightforward enough to do yourself in most states. Your county clerk's office can provide the form and explain how to file it. A lawyer can help if you encounter complications, but most people do not need one.
What happens if I change my name but do not update my Social Security card?
Your legal name has changed, but your Social Security record still shows your old name. This creates problems with taxes, employment, and benefits. Update your Social Security card first, then use that to update everything else.
