How to Change Your Last Name in Arizona: Petition, Hearing, and Updates

There are three ways to change your last name in Arizona: through a marriage license, through a divorce decree, or by filing a name change petition with the Superior Court in the county where you live. The court route runs $252 to $367 in filing fees depending on the county, plus a hearing several weeks out. After the name is legally changed, you update your Social Security card first, then your driver’s license, passport, and everything else.

The Marriage or Divorce Shortcut

If your name change is tied to getting married, you do not need a court petition. Write the new last name on your marriage license application, and once the license is signed and returned to the county recorder, your certified marriage certificate is your legal proof of the new name.

Divorce works the same way, with one limit. Arizona law lets either spouse ask the judge to restore a “former name” as part of the divorce, and the court is required to grant that request if it is made before the decree is signed.¹ The statute says former name, not just maiden name, so you can restore any name you legally held before. You cannot use the divorce to pick an entirely new name. For that, you have to file a separate petition.

Who Can File a Name Change Petition

Any Arizona resident can file an Application for Change of Name with the Superior Court in the county where they live.² For a child, a parent, legal guardian, or next friend can file in the county where the child lives. The statute sets no minimum residency period, but you do need to file in the correct county.

Forms and Disclosures

You need two documents to open the case: an Application for Change of Name for an Adult (or the minor version) and a Civil Cover Sheet. Both are available from the Arizona Judicial Branch website and from your Superior Court clerk’s office.³

The application asks for your current name, the name you want, your date of birth, address, and reason. Under penalty of perjury, you also have to state whether you have any felony convictions, whether fraud or identity-related felony charges are pending against you, and whether the name change is meant to impersonate someone or further a crime.² You confirm the change is in your best interest, and you acknowledge it does not release you from any debts or obligations tied to your old name.

A felony record does not automatically block a name change, but it invites closer review, and the court can set aside a name change later if it turns out the person was convicted of fraud or an identity crime. Some counties also require fingerprints for a background check. Ask your clerk of court whether yours does before you file.

Filing Fees and Waivers

Bring the original application and two photocopies to the Clerk of Court. The state base filing fee is $252, and county surcharges push the total higher, up to $367 in Maricopa County.⁴⁵ Check your county’s fee schedule before you go.

If you cannot afford the fee, you can apply for a deferral or a full waiver. A deferral is available if your household income is at or below 150 percent of the federal poverty level, or if you receive TANF, SNAP, or Supplemental Security Income. A permanent waiver is available if you can show your financial situation is unlikely to improve.⁶

The Hearing

Once you file, the clerk assigns a case number and sets a hearing, typically several weeks out. Publication in a newspaper is not automatic in Arizona. The statute lets the judge order notice by publication or by service on an interested party “if the court deems it proper.”⁷ Many counties do require it in practice, and costs vary by newspaper, so ask the clerk’s office what applies in yours.

At the hearing, bring a government photo ID, your original birth certificate or a certified copy, and copies of everything you filed. The judge reviews your application and your sworn disclosures. If nothing raises a concern and no one objects, the judge signs an Order Changing Name. Crime victims and prosecutors have standing to challenge a name change for up to one year after the order is entered.²

Before you leave the courthouse, buy several certified copies of the order. Each one costs $35.⁴ You will need originals for multiple agencies. Three to five is a sensible starting point; going back later means another trip.

Changing a Child’s Last Name

Minor name changes use the same statute, with extra protections. A parent, legal guardian, or next friend files in the county where the child lives, and the court decides whether the change is in the child’s best interests.²

The other parent has to be notified. If they agree, they can sign a notarized consent that waives further notice. If they do not agree, or you cannot get a signature, you must send a clerk-stamped copy of the application and the hearing notice by certified mail with restricted delivery at least 30 days before the hearing. If you genuinely cannot locate the other parent, ask the court about alternative service.

A child who is 14 or older has to sign a notarized consent or appear in person at the hearing. Note that a name change does not establish paternity and will not add a father’s name to a birth certificate. If you want the birth certificate itself updated, give the court a certified copy of the current one.

Sealing the Record for Safety

If you are protected by an order of protection or an injunction against harassment, you can ask the court to seal your name change application and order so they do not appear in public records. The statute’s language is broad enough that it may cover other safety concerns as well. If your name change was granted on or after January 1, 2009, you can request sealing even after the order was entered.²

Updating Your Records

The court order does not update anything on its own. You contact each agency separately, and the sequence matters.

Social Security First

Start with the Social Security Administration. You can request a replacement card online in some cases or by appointment at a local SSA office.⁸ Bring your certified court order (or marriage certificate or divorce decree) and a current photo ID. The SSA needs a document that shows both your old and new names. If the name change happened more than two years ago, expect to bring additional identity documents.⁹ The replacement card is free and usually arrives in 10 to 14 business days.

Wait at least 48 hours after your SSA visit before heading to MVD or other agencies. Those agencies verify identity against SSA’s database, and the database needs time to catch up.

Arizona MVD

Arizona law requires you to notify the Motor Vehicle Division within 10 days of a name change.¹⁰ Name changes have to be done in person or in writing. Online and phone updates are only for addresses. Bring your certified court order and your current license. A duplicate license or ID card is $12.¹¹

Passport

If your passport was issued in the last year, you can update the name for free by mail using Form DS-5504. If it is older but still eligible for renewal, use Form DS-82.¹² If your passport has been expired for more than five years, or was issued when you were under 16, you have to apply in person as a new applicant.

Taxes

The name on your tax return needs to match the name on your Social Security card. A mismatch can delay processing and any refund. If you changed your name mid-year and have not yet updated it with SSA by the time you file, file under your former name.¹³

Everything Else

Contact your banks, credit card companies, and mortgage servicer directly. You do not need to contact Experian, Equifax, or TransUnion. They receive updates from your creditors, and your credit score is not affected by the name change; the old name stays listed as a former name. Also update your employer’s payroll and HR, your health insurance, your vehicle registration and title through MVD, your voter registration, and any professional licenses you hold. If you own real property, recording a new deed or an affidavit of name change with your county recorder keeps the chain of title clean.
