The Route Through New York Family Court
To legally change your last name in New York, you file a petition in the Family Court of the county where you live. The court reviews your request, publishes a notice in a local newspaper, and holds a hearing. If the judge approves, you receive a court order that becomes your legal proof of the name change. This is the only way to change your name that creates a record the government recognizes.
You do not need a lawyer, though some people hire one. The filing fee is typically between $50 and $100, depending on your county. The entire process usually takes two to four months from the day you file until you receive the final order.
New York does not require you to show "good cause" — meaning you do not have to prove a reason for wanting to change your name. The court will approve your petition unless you are trying to change your name to commit fraud, evade child support, or avoid a criminal conviction.
Key Takeaways
- You file your petition in Family Court in the county where you live, not in a state office.
- The court will publish a notice of your petition in a local newspaper, and you must wait for the publication period before your hearing.
- You do not need to prove a reason for the name change unless the court suspects fraud or evasion of legal obligations.
- The final court order is the document you use to update your name with the DMV, Social Security Administration, and other agencies.
- If you have an outstanding child support obligation, the court may deny your petition or require you to show you are current on payments.
What You Need to File
Before you go to court, gather the documents that prove your identity and residence. You will need a valid photo ID (driver's license, passport, or state ID), proof of your current address (a recent utility bill, lease, or bank statement), and your birth certificate. If you were born outside the United States, bring your naturalization papers or green card.
You also need to know the exact name you want to change to. The court will use this name in the order, so make sure it is spelled correctly. If you are changing your name because of marriage or divorce, you may have other options — see the section below on those situations.
Some counties require you to bring an affidavit (a sworn statement) saying you are not changing your name to commit fraud or evade legal obligations. Ask your county's Family Court clerk whether this is required before you file.
The Filing and Hearing Process
Go to the Family Court in your county and ask for the petition form for a name change. The clerk will give you the form and tell you the filing fee. Fill out the petition with your current name, the name you want, and your reason (if you have one — you can write "personal preference"). Sign the form in front of the clerk or a notary public.
After you file, the court will set a hearing date and order a notice to be published in a newspaper in your county. This publication period usually lasts two to four weeks. The court publishes the notice to give anyone who objects to your name change a chance to speak up — this rarely happens unless there is a custody dispute or criminal history involved.
On your hearing date, go to Family Court and bring all your documents. The judge will ask you why you want to change your name and whether you understand that the change is permanent. Answer honestly and briefly. If there are no objections and nothing in your background raises a red flag, the judge will sign the order on the spot or within a few days.
Name Changes After Marriage or Divorce
If you are changing your name because you got married, you do not have to go to Family Court. Instead, you can use your marriage certificate as proof of your new name. When you explore for a new driver's license or update your Social Security record, bring the original or certified copy of your marriage certificate. Most agencies will accept it without a court order.
If you are divorced and want to take back your maiden name, you have two options. You can ask the judge to include the name change in your divorce judgment — this is the fastest route if your divorce is still in progress. If your divorce is already final, you can file a separate petition in Family Court using the process described above. Bring a certified copy of your divorce judgment to show the court.
If you were married in another state or country, bring the certified marriage certificate or divorce judgment with you when you file. The court will accept it as proof of the name change you are requesting.
Updating Your Name With Government Agencies
Once you have your court order, you need to update your name with the Social Security Administration, the Department of Motor Vehicles, and any other agencies that have your records. Start with Social Security because many other agencies will ask for your Social Security card as proof.
Go to your local Social Security office with your court order, birth certificate, and current photo ID. The staff will update your record and issue a new Social Security card with your new name. This usually takes one to two weeks. You do not need an appointment — walk-ins are accepted, though you may wait in line.
Next, go to the DMV with your court order, birth certificate, and Social Security card (the new one with your new name). You will fill out an process for a new driver's license or state ID. The DMV will take your photo and issue a temporary license on the spot; the permanent card arrives by mail in about two weeks.
Update your name with your bank, insurance company, employer, and any other organization that has your records. Bring a copy of your court order as proof. You do not need the original — most places will accept a photocopy.
What Happens if the Court Denies Your Petition
The court will deny your petition if it finds that you are changing your name to commit fraud, evade child support, or hide from a criminal conviction. If you have an outstanding child support obligation, the court may require you to show proof that you are current on payments before it approves the change.
If your petition is denied, you can ask the judge to explain the reason in writing. You can then address the issue — for example, by getting current on child support — and file a new petition later. There is no rule against filing again after a denial.
If you believe the court made a mistake, you can file an appeal in the Appellate Division of the Supreme Court in your judicial department. This is a more complex process and usually requires a lawyer. Contact your county bar association for a referral if you decide to appeal.
Name Changes for Minors
If you want to change a child's last name, you file the same petition in Family Court, but you must have the consent of both parents or guardians. If one parent refuses, you can ask the court to override the refusal if it is in the child's best interest — for example, if the child has been adopted by a stepparent or if one parent has abandoned the family.
Bring the child's birth certificate and proof of both parents' consent (a signed agreement or a letter from the other parent). If you do not have the other parent's consent, be prepared to explain to the judge why the name change serves the child's welfare. The court will consider the child's age, how long the child has used the current name, and the relationship between the child and each parent.
Frequently Asked Questions
Can I change my name without going to court?
No. A court order is the only legal way to change your last name in New York. You cannot change your name straightforward by using a different name or by having someone call you by a new name. Government agencies and employers will not recognize the change without a court order.
How much does it cost to change my name in New York?
The filing fee ranges from $50 to $100 depending on your county. If you hire a lawyer, expect to pay $300 to $800 for the entire process. You will also pay for a certified copy of your court order (usually $5 to $10 per copy) and for publishing the notice in the newspaper (usually $25 to $75).
Can I change my name if I have a criminal record?
Yes, but the court may deny your petition if it believes you are changing your name to evade a criminal conviction or hide from law enforcement. If you have a criminal record, be honest with the judge about your reason for the change. The court is more likely to approve the petition if your reason is unrelated to your criminal history.
What if I want to change my first name too?
You can change your first name, middle name, and last name all in the same petition. Fill out the form with all the names you want to change and file it in Family Court. The process is the same as changing your last name alone.
Do I need to publish the notice if I am changing my name for safety reasons?
New York law requires publication in all name change cases. However, if you can show the court that publication would put you in danger — for example, if you are fleeing domestic violence — the judge may order the notice to be published in a legal newspaper instead of a public newspaper, or may waive publication altogether. Bring documentation of the threat to your hearing.
