To legally change your last name, you need two categories of documents: proof of who you are now (a government-issued photo ID, a certified birth certificate, and proof of residency) and proof of the legal basis for the change (a certified marriage certificate, a divorce decree that restores a prior name, or a signed court order from a name-change petition). Once you hold the right legal-basis document, you use it to update your Social Security card, driver’s license, passport, and every other record in your name. The exact documents needed to change your last name depend on which path applies to you.
Documents That Prove Your Current Identity
No agency or court will process a name change until you’ve established who you are right now. Gather these before anything else:
- A government-issued photo ID, usually a driver’s license or U.S. passport.
- A certified copy of your birth certificate, with the issuing agency’s seal.
- Proof of residency in the area where you’ll file — a utility bill, lease, or property tax statement works.
Courts need the residency documents to confirm they have jurisdiction over your case. A missing utility bill can send you home from the courthouse, so pull everything together in one folder before you start.
If you’re a lawful permanent resident, keep your immigration documents accessible as well. After your name change is granted, you’ll also need to replace your Green Card by filing Form I-90 with U.S. Citizenship and Immigration Services, either online or by mail.1U.S. Citizenship and Immigration Services.

If You’re Changing Your Name Through Marriage
A certified marriage certificate is the only legal-basis document you need. It links your birth name to your married name, and the Social Security Administration, state motor vehicle agencies, and most other institutions accept it directly, no court order required.2Social Security Administration.

Request a certified copy, meaning one bearing the official seal of the issuing clerk. Plain photocopies won’t be accepted. Order several copies at once, because different agencies may each want their own.
If you entered a civil union or registered domestic partnership instead of a traditional marriage, the Social Security Administration accepts civil union documents from states that issue them as evidence of a name change.3Social Security Administration.

If You’re Returning to a Prior Name After Divorce
The simplest path is a divorce decree that explicitly restores your prior name. When your final decree contains that language, it works the same way a marriage certificate does: present a certified copy to any agency and skip the petition process entirely.
If the restoration language was left out, you have to file a court petition like anyone else. Pull your decree and check before you assume you can take the shortcut.
If You’re Changing Your Name for Any Other Reason
Personal preference, a gender identity transition, or any situation outside marriage and divorce means filing a formal petition with your local county or superior court. The petition itself is a specific document, usually available from the county clerk’s office or the court’s self-help website.
The petition asks for:
- Your full current legal name and the exact new name you want to adopt.
- Your reason for the change. Courts want to confirm you aren’t trying to dodge creditors or commit fraud.
- A criminal history disclosure, including past convictions and any current bankruptcy proceeding.
- A sworn statement that everything in the petition is truthful. Lying can mean denial of the petition or perjury charges.
Fill it out using the identity and residency documents you already pulled together. Misspelled names and wrong dates are among the most common reasons courts reject a filing, so verify every field against your source documents.
Fees and Fee Waivers
Filing fees generally run from about $150 to $500 depending on where you live. Some courts add fingerprinting or background check fees. If you can’t afford the fee, most courts accept a fee waiver application, sometimes called a petition to proceed “in forma pauperis,” which you submit alongside the petition itself. Eligibility usually depends on whether you receive public benefits, whether your income falls below a set threshold, or whether paying would prevent you from covering basic living expenses.
Newspaper Publication
Roughly half of U.S. states require you to publish a legal notice of your intended name change in a local newspaper, usually running for several consecutive weeks so creditors and other interested parties can object. After the run ends, you file proof of publication with the court clerk. Costs typically fall between $30 and $200. Some states waive publication for safety reasons, such as for survivors of domestic violence.
The Court Order
After the hearing, assuming no one has objected and your paperwork is in order, the judge signs a court order approving your new name. This is the single most important document you’ll walk away with. Request several certified copies from the clerk right away. Every agency downstream will want to see one, and many will keep it.
When a Court May Deny the Petition
Judges evaluate petitions based on whether the request is made in good faith and consistent with public safety. Approval isn’t automatic. The file lists several situations that can lead to a denial, and rules vary by state:
- People on sex offender registries, whom many states either bar from changing their names or hold to a higher standard.
- Petitioners with active criminal cases or unresolved litigation.
- Petitioners with outstanding money judgments the change might appear designed to evade.
- People convicted of specific violent crimes, identity fraud, or crimes against children, in a handful of states.
- People under active probation or parole supervision, absent good cause.
Disclose your record honestly on the petition. Courts run background checks, and an omission discovered during the check hurts you more than the record itself.
Changing a Minor’s Last Name
The petition process is similar, but the document list adds parental consent. Courts generally require consent from both parents; if only one parent files, the other must be formally notified and given the chance to object. A noncustodial parent’s consent may not be required if that parent has had no contact and failed to provide support for an extended period (typically two or more years) or has been convicted of serious crimes against the child. In many states, children age 14 or older must also sign their own written consent. Judges apply a “best interests of the child” standard, which gives them broader discretion than in adult cases.
Documents You’ll Need to Update Afterward
Once the court order (or marriage certificate or divorce decree) is in your hand, the sequence matters. Update Social Security first, then your driver’s license, then everything else. Agencies downstream check your name against SSA records, and a mismatch will stall you.
Social Security Card
In some states you can request a corrected card online through a “my Social Security” account.4Social Security Administration.

Form SS-5 – Application for a Social Security Card The SSA accepts only original documents or copies certified by the issuing agency. Photocopies and notarized copies won’t do. There’s no fee.2Social Security Administration. Learn What Documents You Will Need to Get a Social Security Card
U.S. Passport
Which form you file depends on timing:
- If your passport was issued less than one year before your legal name change, file Form DS-5504 by mail with your current passport and proof of the change. No application fee; expedited processing is $60.6U.S. Department of State. Change or Correct a Passport
- If more than a year has passed, file Form DS-82 by mail (if eligible) or Form DS-11 in person. The application fee for a passport book is $130; applying in person adds a $35 acceptance facility fee for a total of $165.7U.S. Department of State. United States Passport Fees
You’re eligible to use Form DS-82 only if your most recent passport was issued when you were 16 or older and within the last 15 years. Otherwise, Form DS-11 at an authorized acceptance facility is the required path.6U.S. Department of State. Change or Correct a Passport
Driver’s License or State ID
Once Social Security has your new name, go to your state motor vehicle agency with your certified court order (or marriage certificate), your updated Social Security card, and proof of residency. Fees vary by state. Having a photo ID in your new name makes every remaining update easier.
Employer and Tax Records
Tell your employer so they can update payroll and your Form W-2. Employers are recommended to update Section 2 of your Form I-9 when they learn of a legal name change, and may ask for a marriage certificate or court order as supporting documentation.8U.S. Citizenship and Immigration Services. Recording Changes of Name and Other Identity Information for Current Employees A name mismatch between your tax return and your Social Security record can cause an electronically filed return to be rejected, so get Social Security updated well before tax season.9Internal Revenue Service.

Voter Registration
Update your voter registration or you may run into problems at the polls. Visit vote.gov, select your state, and follow the instructions. Some states let you update online; others require a change-of-information form or full re-registration. Watch the state deadline if an election is approaching.10USAGov.

Banks, Property, and the Rest
Work through banks and credit cards, health insurance, HR, professional licensing boards, and property records. If you own real estate, update the name on your deed by filing a new deed (often a quitclaim deed, transferring the property from your old name to your new name) with your county recorder’s office. Most financial institutions and licensing agencies accept a certified copy of your court order or marriage certificate. Order plenty of certified copies up front, because many agencies keep theirs on file and won’t return it.
