California: Adult Legal Name Change Requirements

Requirements one by one

File in superior court using the mandatory forms

An adult ordinarily files in the superior court of the county where the adult
lives. California states no minimum residence period. A narrow nonresident
route is available in the county connected to a California birth certificate or
marriage record when the petition seeks to change that record.

The ordinary adult packet uses mandatory Judicial Council forms NC-100 and
NC-110. The statute requires place of birth and residence, present and
proposed names, and the reason for the change. NC-110 also gathers date of
birth, current address, the birth-certificate sex entry used for a federal
database search, and penalty-of-perjury declarations concerning correctional
jurisdiction and Penal Code § 290 registration.

California does not require a petitioner fingerprint card

The ordinary adult does not submit fingerprints or a general FBI criminal-
history report. The court instead checks CLETS/CJIS—or uses local law
enforcement if necessary—to determine whether the petitioner is required to
register as a sex offender under Penal Code § 290.

An adult in CDCR jurisdiction or county jail may petition, but must provide a
copy of the petition to CDCR or the sheriff as § 1279.5 directs.

The ordinary route publishes for four weeks

The ordinary order to show cause sets a date 6 to 12 weeks after the order,
unless the court chooses another time. The order is published in a county
newspaper of general circulation once weekly for four successive weeks. If
the county has no such newspaper, the clerk posts it in three public places for
the same period. Proof must be made to the court.

A hearing occurs only when an objection is filed that shows good cause. If no
objection is filed at least two court days before the scheduled date, the court
may grant the petition without a hearing. Local handling still varies, so the
official self-help guide tells filers to ask the clerk whether an appearance is
needed.

Safety and gender-identity proceedings avoid ordinary publication

A qualifying active Safe at Home participant seeking the change to avoid
domestic violence, stalking, sexual assault, or human trafficking is exempt
from publication. The statute substitutes confidential-name language in the
petition and order, protects the current name from public calendars and
indexes, and allows a sealing request under specified findings.

California's separate adult gender-identity name track changed on July 1,
2026. Current § 1277.5 requires the court to grant that petition without a
hearing within six weeks and exempts it from publication, subject to the
sex-offender restriction in § 1279.5.

Registry status creates a heightened denial rule

A court must deny the petition of a Penal Code § 290 registrant unless it finds
that granting the change is in the interest of justice and will not adversely
affect public safety. If granted, the petitioner must notify the specified local
law-enforcement authority within five working days.

Court fees and newspaper costs are separate

California Courts currently lists the filing fee as $435-$450, depending on
the court. An eligible petitioner may request a fee waiver, but the ordinary
waiver does not cover newspaper publication. A certified decree currently costs
$40 unless waived.

The decree changes the legal name, but government records do not update
automatically. The petitioner obtains certified copies and presents them to the
agencies whose records need changing.

What trips people up

• NC-100 is not used for the gender-identity track. The current NC-100
  instructions direct those petitioners to NC-200.
• No fingerprint card does not mean no screening. The court performs the
  statutory sex-offender-status check through CLETS/CJIS.
• The fee waiver does not pay the newspaper. Publication cost remains
  separate in the ordinary route.
• The July 1, 2026 special-track rule is now operative. Older materials that
  describe an objection period for an adult gender-identity petition are stale.

Common questions

Will I have to attend a hearing?

For an ordinary petition, only if a good-cause objection is filed or the local
court otherwise requires an appearance consistent with its procedures. If no
timely objection is filed, the statute allows the order without a hearing. The
current adult gender-identity track requires a no-hearing order within six
weeks.

Can publication be kept confidential for safety?

Yes, for the statute's qualifying Safe at Home route. It applies when the active
program participant seeks the change to avoid domestic violence, stalking,
sexual assault, or human trafficking and satisfies the confidential-name
requirements.

Does the court automatically update my IDs?

No. Obtain certified copies of the decree and submit them separately to each
agency or record keeper.
