How to change your last name

The process depends on why you want to change it. If you're getting married, you can change your name through the marriage license itself in most states — no separate court order needed. If you're divorced, you can request a name change as part of the divorce decree, or file for one afterward. If you want to change your name for any other reason, you'll file a petition with your local court, attend a hearing, and get a court order. The whole process typically takes four to eight weeks, though timing varies by state and how busy your courthouse is.

Your state's rules matter more than anything else. Some states let you change your name on the marriage license application; others require you to do it after the marriage is official. Some charge a fee; some don't. Some require you to publish your name change in a newspaper; others don't. Start by calling your county clerk's office or checking your state court's website — they'll tell you the exact steps and forms you need.

  • Name changes for other reasons require a court petition, a hearing, and a judge's order — the process takes four to eight weeks on average.
  • Your county clerk's office or state court website has the specific forms, fees, and rules for your location.
  • Some states require you to publish your name change in a newspaper; others do not.

Changing your name through marriage

When you get married, you have the option to take your spouse's last name, keep your own, use a hyphenated name, or combine parts of both names. How you make this official depends on your state.

In most states, you can indicate your new name on the marriage license application itself. You fill out the form with the name you want to use after marriage, and once the license is signed and filed, that becomes your legal name. No additional paperwork is needed. Some states let you do this; others require you to change your name after the marriage is official, using a separate process.

Call your county clerk's office before you apply for the marriage license and ask: "Can I change my name on the marriage license application, or do I need to file separately after the marriage?" They'll tell you which applies in your county. If you need to file separately, they'll give you the form and tell you where to send it.

Changing your name through divorce

You can request a name change as part of your divorce case. When you file for divorce, you can ask the court to restore your maiden name or change to any other legal name you choose. The judge can grant this in the divorce decree itself, so you get one court order that covers both the divorce and the name change.

If you didn't request a name change during the divorce, or if you want to change your name after the divorce is final, you can file a separate petition with the court. The process is the same as a name change for any other reason — you file a petition, pay a fee (which varies by state), and attend a hearing. The judge will grant the order unless there's a reason not to (such as intent to defraud creditors, which is rare and requires evidence).

Ask your divorce attorney or your county clerk whether it's easier to request the name change as part of the divorce or to file separately afterward. In most cases, doing it during the divorce saves you a second court filing and fee.

Changing your name by court petition

If you want to change your name for any reason other than marriage or divorce — whether for personal preference, cultural reasons, or to distance yourself from a previous identity — you'll file a petition with your district or circuit court. This is a straightforward civil process.

First, get the petition form from your county clerk's office or your state court's website. The form asks for your current name, the name you want, and your reason for the change. You'll fill it out, pay the filing fee (typically $100 to $300, though this varies), and submit it to the court. Some states require you to serve a copy on the district attorney or publish the name change in a local newspaper; others don't. Your clerk will tell you what applies in your county.

After you file, the court will schedule a hearing. You'll go to court, tell the judge why you want to change your name, and the judge will decide. In the vast majority of cases, judges grant name changes unless there's evidence of fraud or intent to evade legal obligations. Once the judge signs the order, you have a court document that proves your new legal name.

Updating your name with government agencies and institutions

Once you have your court order (or marriage license, if that's how you changed your name), you need to update your name with Social Security, the DMV, your employer, your bank, and any other institution that has your legal name on file. This is separate from the court process and takes additional time.

Start with Social Security. Go to your local Social Security office with your court order or marriage certificate and a photo ID. They'll update your record, and you'll get a new Social Security card in the mail within two weeks. Next, go to your state's DMV with the same documents and get a new driver's license or ID card. Then contact your bank, employer, insurance company, and any other institution where your name appears. Each one has its own process, but they all need the same documents: your court order or marriage certificate and a photo ID.

Keep copies of your court order or marriage certificate. You'll need them multiple times, and institutions sometimes ask for originals. Order extra certified copies from your county clerk when you first get the order — it's cheaper than ordering them one at a time later.

State-specific rules and variations

Name change rules differ by state. Some states charge no fee for name changes; others charge $50 to $300. Some require newspaper publication; others don't. Some allow name changes on the marriage license; others require a separate filing. Some states have waiting periods; most don't.

The fastest way to find your state's specific rules is to call your county clerk's office or visit your state court's website and search for "name change petition" or "name change procedure." They'll have the form, the fee, the timeline, and any special requirements. If you're changing your name through marriage or divorce, ask the clerk whether you can do it on the license or decree itself, or whether you need a separate petition.

What happens if you change your name informally

You cannot legally change your name just by using a new name. If you want to change your name on government documents, financial accounts, or legal records, you need a court order, a marriage license, or a divorce decree that shows the change. Using a new name socially is one thing; changing it legally is another.

If you try to update your Social Security record, driver's license, or bank account without a court order or marriage certificate, they'll reject the request. This is why the court process exists — it creates an official record that institutions can verify. Without it, you have no legal proof that the name change is legitimate.

Frequently Asked Questions

Do I need a lawyer to change my name?

No. Name changes are straightforward civil procedures, and you can file the petition yourself. Your county clerk's office will give you the form and tell you where to file it. If you're changing your name through marriage or divorce, you may want a lawyer for the marriage or divorce itself, but the name change part is simple enough to handle alone.

How much does it cost to change your name?

Costs vary by state. Marriage-related name changes are often free or cost only the marriage license fee. Court petitions for name changes typically cost $100 to $300 in filing fees, though some states charge less. Call your county clerk to find out the exact fee in your area.

Can I change my child's last name?

Yes, but the process is more complex. You'll need a court petition, and in most states you need consent from both parents, or you need to show that one parent has abandoned the child or had parental rights terminated. The court will consider what's in the child's best interest. Talk to a family law attorney about this one — the rules vary significantly by state.

How long does a name change take?

Court-ordered name changes typically take four to eight weeks from filing to final order, depending on how busy your courthouse is and whether the judge needs to hold a hearing. Name changes through marriage or divorce happen as part of those processes, so timing depends on how long the marriage license or divorce takes.

Do I have to publish my name change in the newspaper?

It depends on your state. Some states require newspaper publication; others don't. Your county clerk will tell you whether it's required in your area. If it is required, the court will tell you which newspaper to use and how long the notice needs to run.
