Wisconsin Name Change Laws: How to Legally Change Your Name
Wisconsin's name-change law lives in an unusual place in the code, chapter 786, filed under a probate and property title rather than the family law chapters most other states use. Adult and minor petitions both run through it, filed in circuit court, with mandatory newspaper publication as the default.
Wisconsin also has the strongest sex-offender restriction confirmed anywhere across this cluster's research: a reporting-status sex offender is outright prohibited from changing their name at all while their reporting duty is active, not merely subject to a heightened standard, and attempting it is a felony.

How to Legally Change Your Name in Wisconsin
An adult or a parent on behalf of a minor petitions in circuit court in the county of residence, under . Wisconsin residency is required, though no specific duration is spelled out in the sections read. Standard forms include CV-450 (Petition for Name Change, Adult or Minor 14 and Older), CV-451 (Petition for Confidential Name Change), CV-455 (Petition for Change of Name, Minor Under 14), and CV-470 (Order for Name Change), available through the Wisconsin Court System's self-help center.
There is no single confirmed statewide filing fee; Dodge County's published fee, $164.50, is a representative county example rather than an authoritative statewide figure. Confirm the exact amount with your circuit court clerk.
A licensed professional faces one additional, narrower restriction: 786.36(3) lets a state licensing board or commission block a name change if it would unfairly compete with or mislead the public, with specific exceptions for teachers and for changes driven by marriage or divorce.
Changing a Minor's Name
For a minor under 14 with both parents living, both parents ordinarily petition jointly, or a guardian or legal custodian petitions if parental rights have been terminated. A single parent may petition without the other parent's notice or consent if that other parent was convicted of one of roughly 25 enumerated violent or sexual offenses against a child (786.36(1m)(c)).
Where a single parent petitions under the general rule rather than that conviction exception, the nonpetitioning parent must be served notice in the same manner as a summons, in addition to publication (786.37(2)).
Restoring Your Name After Divorce
No dedicated Wisconsin statute for divorce-based name restoration could be located, including a direct search of chapter 767, the state's «Actions Affecting the Family» chapter, and its annulment section. A divorced person appears to use the same general 786.36 petition process as anyone else seeking a name change; confirm the current practice with your circuit court clerk.
Publication and the Confidential Alternative
A Class 3 notice under chapter 985 must be published before the court will hear the petition, stating the nature of the petition and the hearing's date and place (786.37(1)).
Wisconsin offers a genuine alternative to publication: a Petition for Confidential Name Change (CV-451) waives publication if the judge finds publication would endanger the petitioner and the change is not sought to avoid debt or conceal a criminal record (786.37(4)). Confidentiality protections for the resulting records are set out separately in 786.36(2m).
Restrictions: The Strongest Sex-Offender Bar in This Batch
Wisconsin's restriction structure works differently depending on who is asking. There is no general felony bar that stops an adult from petitioning on their own behalf. The enumerated-conviction list under 786.36(1m)(c) described above instead strips a nonpetitioning parent's notice and consent rights in a minor's case, rather than barring that parent from anything themselves.
For a reporting-status sex offender, the rule is categorical rather than discretionary: makes it an outright prohibition to change your name, or to identify by an unregistered name, before your reporting requirement ends. This is stated plainly because it is easy to soften into generic «restrictions apply» language, and that would understate it: violating this ban is a Class H felony, with a lesser fine and imprisonment tier available for certain lower-level predicate offenses. Among the ten states in this batch, this is the strictest restriction confirmed, an outright ban independently backed by felony-level criminal exposure rather than a heightened court-review standard.
Name Change After Marriage
Wisconsin has no statute dedicated to marriage-based name changes. A spouse who wants to adopt a new name at marriage does so administratively, presenting the marriage certificate to the Social Security Administration and the DMV rather than filing a court petition. For the federal-level steps involved, see name change after marriage.
