Northwest Justice Project

Learn how to get a legal name change. Use this if you need a name change for any reason including safety, religion, sex, gender identity, transgender status, immigration status, marital status or other reasons. There are 2 kinds of name changes in Washington — sealed name changes and name changes that are not sealed. This guide has instructions for both kinds and forms for a sealed name change. 

1. Common questions

How do I change my name?

There are 4 ways to change your name in Washington state: 

  • By court order
  • Through marriage, divorce or adoption
  • By common law (This method may not be recognized by everyone and may not be considered a “legal” name change.)
  • By amending a minor child's birth certificate (This is only for children born in Washington.)

This guide explains how to change your name by court order. In most situations, it’s a simple process you can do by yourself, without a lawyer.

You might also be able to change your name during your citizenship naturalization process. You should talk to your immigration lawyer if you want to try to get a name change that way.

How do I change my name using a marriage, divorce or adoption?

You can change parts of your name during the regular processes of marriage, divorce or adoption. 

  • Marriage: You might only be able to change your last name if using a marriage to do so. If you want to change your first and middle name, you may still need to complete a court ordered name change. Use the final official marriage license as proof of your legal last name change.
  • Divorce: You can change your name during any kind of divorce. You can ask to change your first, middle and last name during a divorce. There is a section for requesting name changes on the standard Washington state court form for divorce: FL Divorce 201 (Petition for Divorce). You can’t use divorce or parentage cases to change a child’s name unless there is domestic violence.
  • Adoption: Courts generally allow name change requests in adoptions as a normal part of the adoption case. You don’t need to file a separate case. You can ask to change first, middle and last names during an adoption.

Who can get a court-ordered legal name change?

In Washington, you can ask the court to legally change your name if you’re an adult or an emancipated minor. A court-appointed guardian can ask the court to change the name of the adult they have guardianship over. A parent or court-appointed guardian can ask the court to change a minor child's name, although the court will usually require notice to any other parent or guardian. 

If I change my name by court order, will it be confidential (“sealed”)?

Not unless you file a special type of case to make it confidential (“sealed”). Sealed name changes in Washington are more private than non-sealed name changes. The record of your name change will be kept as confidential as possible if you ask for a sealed name change. 

Name changes don’t have to be published in the newspaper in Washington.
