Adult Legal Name Change Requirements in California
At a glance
| Governing law and court | Cal. Code Civ. Proc. §§ 1275-1279.6; petition in the superior court of the county where the adult resides (§§ 1275-1276) |
|---|---|
| Who may petition and residency | An adult may petition in the county of residence; no minimum residence period is stated. A narrow nonresident route exists in the California county tied to a California birth certificate or marriage record that the petitioner seeks to change (§ 1276(a), (g)). Section 1279.5 preserves the common-law name-use right, subject to its listed restrictions |
| Petition contents and oath | State place of birth and residence, present name, proposed name, and reason (§ 1276(a)(2)). Mandatory forms NC-100/NC-110 add date of birth, current address, sex shown on the birth certificate for a federal database search, and penalty-of-perjury declarations about correctional jurisdiction and Penal Code § 290 registration |
| Criminal background check | No petitioner-supplied fingerprint card or general FBI report. The court checks CLETS/CJIS (or asks local law enforcement) to determine Penal Code § 290 sex-offender-registration status (§ 1279.5(f); NC-110) |
| Publication or notice | Ordinary petition: publish the order to show cause in a county newspaper of general circulation once weekly for four weeks; if no such newspaper exists, the clerk posts it in three public places. The order usually sets the matter 6-12 weeks out, and proof is made to the court (§ 1277(a)(1)-(3)). Incarcerated or jailed petitioners must give the petition to CDCR or the sheriff (§ 1279.5(c)) |
| Safety, confidentiality, and special tracks | A qualifying active Safe at Home participant seeking to avoid domestic violence, stalking, sexual assault, or human trafficking is exempt from publication; current and proposed-name information receives statutory confidentiality protections, and sealing may be requested (§ 1277(b)). An adult petition to conform a name to gender identity is exempt from publication and, since July 1, 2026, must be granted without hearing within six weeks, subject to § 1279.5 (current § 1277.5) |
| Hearing and grant standard | Ordinary route: a hearing occurs only if an objection is filed that shows good cause; if none is filed at least two court days before the scheduled date, the court may grant without hearing (§ 1278(a)). At a hearing the court may examine witnesses under oath and make the order or dismiss as right and proper. Current adult gender-identity route: grant without hearing within six weeks (§ 1277.5(a)) |
| Grounds for denial or restriction | A Penal Code § 290 registrant's petition must be denied unless the court finds granting it is in the interest of justice and will not adversely affect public safety; a successful registrant must notify specified local law enforcement within five working days (§ 1279.5(e)). People in CDCR custody or county jail may petition but must provide the required agency copy (§ 1279.5(b)-(c)) |
| Fee and post-order effect | $435-$450 court filing fee; ordinary fee waiver available, but it does not cover newspaper cost. A certified decree currently costs $40 unless waived; records are not updated automatically, so the petitioner uses certified copies with each agency (California Courts Self-Help) |
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.
