How to Legally Change Your Name in California

A legal name change in California is a court process, not a form you file with the DMV. It ends in a court order, and that order is what every other agency wants to see.

Where it is filed

Name change petitions are filed in the superior court. As with every civil matter in California, that means the superior court for the relevant county — one of 58, each with its own filing procedure and local forms.

Publication in a newspaper

This is the step people do not expect. According to the California Courts self-help centre, before a judge can decide, the forms must be published in a newspaper for one month.

There is an important exception: publication is not required where the name change aligns with gender identity recognition.

What it costs

The filing fee is $435 to $450, and newspaper publication is charged separately by the newspaper. Fee waivers are available if you cannot afford the filing fee, and that is a standard, routine request rather than an unusual one.

How long it takes

A judge typically decides in about two to three months. Much of that is the publication month plus the court’s scheduling.

Changing a child’s name

Where one parent petitions to change a child’s name, the other parent may need to be served with a copy. A parent who objects can respond using Form NC-120. This is the part that most often turns a straightforward petition into a contested one.

The order is the beginning, not the end

The court order is what lets you update everything else — driver’s licence, passport, Social Security record, bank accounts, employment records. Each agency has its own process and most want a certified copy rather than a photocopy, so order several certified copies from the clerk while you are there.

Marriage and divorce are different routes

A name change taken through marriage or restored through a divorce judgment does not require this petition — the marriage certificate or the dissolution judgment serves the same evidentiary purpose.

Fees and local procedures differ by county and change. Confirm with the superior court where you will file.
