To change your last name in the U.S., you either ride an existing life event or file a court petition. Marriage and divorce give you the easy path: the marriage certificate or divorce decree is itself the legal proof of your new name. For every other reason, you file a petition in your local court, possibly publish a notice in a newspaper, attend a short hearing, and walk out with a court order. From there, the work shifts to updating records, starting with Social Security. Start to finish, most petitions take two to ten weeks, though some states run longer.
The Two Paths
Which path applies to you depends entirely on the reason for the change. If it’s marriage or divorce, no court petition is needed. For anything else, including changing back to a former name years after a divorce, you file a standalone petition with the court. The rest of the process (updating Social Security, your passport, your license, and your financial records) is the same either way. What differs is the document you carry into each agency: a marriage certificate, a divorce decree, or a signed court order.
Changing Your Last Name Through Marriage
When you apply for a marriage license, you can indicate your new name on the application. After the ceremony, your marriage certificate reflects it, and that certificate is the legal proof you present when updating government records and accounts. There’s no separate filing, no hearing, and no additional fee beyond the marriage license itself.
Changing Your Last Name Through Divorce
Most courts let you request a name restoration, typically to a maiden or prior name, as part of the divorce petition. The judge writes the name change into the final divorce decree, making it legally binding at the same moment the divorce is finalized. If you didn’t request the change during the divorce, you can still get your prior name back, but you’ll go through the full court petition process described below.
Filing a Court Petition
Most jurisdictions require you to be at least 18 and a resident of the state where you file. Residency requirements vary; many states expect six months to a year of residency before you can petition. Courts will deny a petition if the change is meant to dodge debts, evade law enforcement, or commit fraud. Some states also restrict petitions from people with felony convictions, registered sex offenders, and individuals on parole or probation, though the rules differ sharply. If you have a criminal record, check your state’s rules before filing.
Get the petition form from your local court’s website or clerk’s office. Many courts now accept electronic filing, though in-person and mail filings are still options. The form asks for your current legal name, the name you want, your reason for the change, and basic biographical details. You’ll typically attach a certified copy of your birth certificate and a valid photo ID.
Filing fees range from under $100 in some states to over $400 in others like California, Florida, and Louisiana. If you can’t afford the fee, you can file a financial hardship affidavit asking the court for a waiver. Courts evaluate income and expenses and may waive the fee entirely. Once the court accepts your filing, you’ll receive a case number along with either a hearing date or instructions on the next steps, which often include a background check and publication.
Publishing Notice
Roughly half of U.S. states require you to publish a notice of the intended name change in a local newspaper before the hearing. The notice typically runs for three to four consecutive weeks and includes your current name, proposed new name, and hearing date. Costs vary widely, roughly $30 to several hundred dollars depending on the newspaper. The point is transparency: creditors, law enforcement, or anyone with a legitimate concern gets a chance to object. Objections are uncommon in practice.
Some states waive publication for safety reasons. Domestic violence survivors most often qualify, and stalking victims and others facing threats may also be eligible. In states that grant a waiver, the court often seals the name change records so your new name doesn’t appear in public databases. You’ll typically file a separate motion explaining the safety concern, and the judge rules on the waiver at or before the hearing.
The Court Hearing
The hearing is usually scheduled several weeks after filing to allow for publication and any required background check. It isn’t a trial. The judge confirms your identity, asks why you want the name change, and confirms the request isn’t for fraudulent purposes. If no one has objected and your paperwork is in order, the hearing often lasts just a few minutes. The judge signs a court order granting the change. Some courts waive the hearing entirely when the petition is straightforward and uncontested.
Before you leave the courthouse, get several certified copies of the order from the clerk. They cost only a few dollars each, and you’ll need them for nearly every record update that follows.
Changing a Child’s Last Name
A parent or legal guardian files the petition on the child’s behalf. The biggest variable is consent: most courts expect both parents to agree, and the non-petitioning parent signs a notarized consent form filed with the petition.
If the other parent objects or can’t be located, you must formally serve them with notice of the hearing, either by certified mail or a process server. At the hearing, the judge evaluates whether the change serves the child’s best interests, weighing the child’s relationship with each parent, how long the child has used the current name, and any potential for confusion. Children 14 or older may need to consent themselves. Courts rarely approve a child’s name change over a fit parent’s objection without a compelling reason.
Updating Your Social Security Card
Update Social Security first, because nearly every other agency checks your name against SSA records. The process is free. Fill out Form SS-5 and submit it to your local Social Security office in person or by mail.1Social Security Administration. Application for Social Security Card
You’ll need a document showing both your old and new names, such as your court order, marriage certificate, or divorce decree, along with proof of identity (a U.S. driver’s license, state ID, or passport) and proof of citizenship or immigration status (typically a birth certificate or U.S. passport). SSA returns originals after processing. If the name change happened more than two years ago, SSA may ask for additional proof of identity in both names.1Social Security Administration.

Updating Your Passport
The passport process depends on how recently your current passport was issued. If your name changed less than one year after your most recent passport was issued, use Form DS-5504 for a corrected passport at no charge, unless you request expedited processing, which adds $60.2U.S. Department of State. Name Change for U.S. Passport or Correct a Printing or Data Error Mail the form with your current passport, one passport photo, and an original or certified document showing the legal change.3U.S. Department of State. DS-5504 – Application for a U.S. Passport for Eligible Individuals
If more than a year has passed since either your passport was issued or your name was legally changed, renew using Form DS-82 (if eligible for mail renewal) or apply in person with Form DS-11. The adult passport book renewal fee is $130. In-person applications with DS-11 add a $35 facility acceptance fee.4U.S. Department of State. Passport Fees
Taxes, Medicare, and Voter Registration
The IRS doesn’t have a standalone name change form. Your name on your tax return must match SSA records, so update Social Security first and use your new name when you next file. Mismatches can trigger a rejected return or a delayed refund.5Internal Revenue Service. Update My Information
Medicare records are also maintained through Social Security, so updating your SSA record starts the Medicare update automatically. You can verify through your my Social Security account, by calling SSA at 1-800-772-1213, or by visiting a local office.6HHS.gov. How Do I Report a Change of Name or Address to Medicare
Voter registration also needs updating, and timing matters. If an election is approaching, update well before your state’s registration deadline so your name matches your ID at the polls. Most states let you update online, by mail, or in person through the state election office or secretary of state.
Banks, Credit Bureaus, and Property Title
Banks, credit card companies, and investment firms will each want a copy of your court order, marriage certificate, or divorce decree. For an employer-sponsored retirement account like a 401(k), contact the plan administrator directly, since the plan’s own rules govern how beneficiary information is updated.
Credit bureaus don’t automatically learn your new name. Contact Equifax, Experian, and TransUnion individually. Equifax, for example, accepts the change through its online dispute center with a supporting document such as your court order, new driver’s license, or marriage certificate; allow up to 30 days for processing, or send the documents by phone or mail instead.7Equifax. How to Change or Update Your Name on Your Credit Report Make clear you’re reporting a legal name change, not disputing an error.
If you own real estate, updating the title typically requires recording a quitclaim deed with your county recorder’s office. The deed transfers the property from your old name to your new name. It must include the property’s legal description (not just the street address), be signed before a notary, and be recorded in the county where the property sits. Some counties also require a certificate of value or a tax exemption form.
Driver’s License, Professional Licenses, and Trusted Traveler
Update your driver’s license or state ID after Social Security. Bring your court order or marriage certificate and a current form of ID to the DMV. Professional licenses (for healthcare providers, attorneys, accountants, and others) need updating with the relevant licensing board, and each profession has its own process.
Trusted traveler memberships like Global Entry also need updating. The update is free but requires your passport to already reflect the new name. Online requests can take up to eight weeks; in-person updates at an enrollment center take effect immediately.
Legal Documents to Revisit
A name change doesn’t automatically update your existing legal documents. Review your will, any trusts, your power of attorney, and your healthcare directive. If these reference you by your old name and someone later challenges them, the mismatch can cause delays or disputes during probate or in a medical emergency.
If you’re in the middle of a lawsuit, custody case, or other court proceeding, notify the court and all parties. Failing to do so can create confusion in the record, and in adversarial proceedings it can be used to question your credibility. If you hold a security clearance or a sensitive government position, expect to document the change through your agency’s security office; that isn’t a threat to the clearance itself, but the paperwork is required.
Where Petitions Get Stuck
The most common reason petitions stall is incomplete paperwork. A missing document, a blank field, or an uncertified copy of your birth certificate can send you back to the beginning. Confirm your court’s specific requirements before filing.
Third-party objections during the publication period are uncommon but do occur, usually from creditors worried about debt collection. The judge hears both sides and decides whether the objection has merit; an objection alone doesn’t block the change.
If you have a criminal record, be ready to explain your reason in more detail. Courts are trying to prevent misuse of the process, not punish people with records. A clear, honest reason unrelated to evading accountability, along with evidence of rehabilitation, goes a long way. In states with strict felony bars, you may need a pardon or a fully completed sentence before you’re eligible to petition.
