Wisconsin: Adult Legal Name Change Requirements

Requirements one by one

File CV-450 in the county where you live

Under § 786.36(1), an adult Wisconsin resident petitions the circuit court
in the county of residence. The statute sets no six-month or other minimum
residence period. It authorizes the court to grant the change if no sufficient
cause is shown to the contrary.

The mandatory adult form, CV-450, asks for the current address and county,
birth date and state, birth-certificate state and name, current job,
professional-license status, registrable-sex-offender status, requested name,
reason, and whether Wisconsin birth or marriage records should be changed. The
petitioner signs under penalty of false swearing; the form is not notarized.

Wisconsin does not require the adult to submit fingerprints, an FBI or state
criminal-record report, or a general criminal-history schedule. CV-450 instead
uses a yes/no registration-status statement because current sex-offender
reporting creates a statutory bar.

Publish three weekly notices before the hearing

§ 786.37(1) requires notice of the nature of the petition and the
hearing's time and place. A class-3 notice means three insertions. Under
§ 985.07(3)(a) and § 985.01(1m)(a), those insertions run once each week for consecutive weeks,
and the last must be at least one week before the hearing unless another law
specifies otherwise.

Current form CV-490 directs the filer to publish the hearing notice in a
qualifying local newspaper and obtain its Declaration of Publication. Follow
the circuit's practice for filing that declaration before the hearing or
presenting it at the hearing.

The confidential route starts private and has no publication

A petitioner who could be endangered by publication uses CV-451 and the
confidential form set. Under § 786.37(4), the clerk keeps that petition
confidential on filing and ordinary publication initially does not apply.

At the hearing, the petitioner must prove by a preponderance of the evidence
both that publication could endanger them and that the change is not sought to
avoid a debt or conceal a criminal record. If the court makes that finding,
§ 786.36(2m) makes all related name-change records confidential. Vital
Records, the register of deeds, and a local registrar may disclose the protected
information only by court order based on good cause and a finding that
disclosure will not jeopardize the petitioner's safety.

Wisconsin has no separate gender-identity name-change track. The 2025-2026
bills that would have eliminated publication for a gender-identity-conforming
petition did not pass.

Attend the hearing and prove the published or confidential route

Both routes have a hearing. In an ordinary case, the petitioner provides the
publication declaration. In a confidential case, the petitioner proves the
endangerment and proper-purpose elements. The judge may place the petitioner
under oath and ask about the petition. The governing standard remains whether
any sufficient cause is shown against granting the change.

Registration and professional licensing can prevent the change

Under § 301.47(1)-(2), a person who remains subject to Wisconsin sex-offender
reporting may not change their legal name before release from the reporting
requirements. That is a categorical statutory bar, not merely a disclosure.

Section 786.36(3) separately permits a professional licensing board, after
a hearing, to prevent a licensee from changing away from the licensed name if
the change would unfairly compete, mislead the public about identity, or harm
the profession or public. The restriction excludes Wisconsin public-school
teachers, marriage or divorce changes, and professions without the specified
state licensing body.

Wisconsin enacted no broader violent-felony bar in 2026: SB 146 was vetoed and
AB 124 failed. The official § 786.36 annotation nevertheless reports that the
state's identification interest during incarceration and parole was sufficient
cause to deny the particular convicted-felon petition in Williams.

Budget for filing, publication, recording, and copies

The statewide fee table updated July 13, 2026 lists $164.50 for a no-money-
judgment civil case, expressly including a name change. Newspaper publication,
certified copies, the $30 register-of-deeds recording fee, and applicable
Vital Records charges are separate. An electronically filed case may also have
the table's $35 per-party e-filing fee.

A petitioner unable to pay may request a waiver under § 814.29 using
CV-410A, the Petition for Waiver of Fees and Costs–Declaration of Indigency.
Ask the clerk which expenses an approved order covers; the newspaper is a
separate provider.

The clerk transmits Wisconsin vital-record changes

After judgment, § 786.36(2) requires the order to be entered in the court
record and a certified copy recorded with the county register of deeds. If the
person was born or married in Wisconsin, the clerk sends a certified abstract
and the prescribed fee to the state registrar. As amended by 2025 Wisconsin Act
234, the registrar corrects the state birth or marriage record and directs
corresponding corrections in the register-of-deeds and local-registrar records.

The court process does not automatically update a driver's license. Wisconsin
DMV requires the Social Security name change first, a 48-hour wait, and proof
such as a certified court order at a DMV customer service center.

What trips people up

• Three publications are not the whole timing rule. They run weekly, and
  the final insertion must be at least one week before the hearing.
• A confidential petition starts confidential, but the hearing still
  matters. The petitioner must prove both statutory elements by a
  preponderance.
• Registration status is a bar, not a background-check instruction. Do not
  order fingerprints or a criminal report that CV-450 does not request.
• Professional-license status has its own narrow rule. It does not create a
  general employer-approval requirement.

Common questions

Does every Wisconsin adult need a criminal-background check?

No. The statewide procedure requires no fingerprints or applicant-supplied
record report. CV-450 asks whether the petitioner is a convicted sex offender
required to register because § 301.47 bars that name change while reporting
continues.

Can publication be waived for safety?

Yes. Use the confidential forms and prove by a preponderance that publication
could endanger you and that the request is not made to avoid debt or conceal a
criminal record.

Is a hearing required?

Yes. Current Wisconsin Courts instructions assign a hearing in both ordinary
and confidential cases.
