What Is the Wisconsin Sex Offender Registry?

The Wisconsin Sex Offender Registry is a statewide system administered by the Department of Corrections that requires certain individuals to report identifying, residential, employment, and other personal information following qualifying criminal cases. The stated purpose of the registry is public protection – not punishment – but failure to comply with registration requirements is prosecuted as a separate criminal offense.

Registration requirements are governed primarily by Wisconsin Statute § 301.45, with additional authority granted to courts under § 973.048 to impose registration in specific cases.

At Chirafisi Anderson, S.C., we represent individuals facing registration exposure at every stage of a case – from charging and plea negotiations to sentencing and post-conviction proceedings. Our attorneys focus on limiting registration obligations where possible, preserving statutory exceptions, and defending against alleged registration violations with a clear understanding of how courts and prosecutors apply Wisconsin’s registry laws in practice.

Who Is Required to Register as a Sex Offender in Wisconsin

A person may be required to register if they fall into any one of several statutory categories, including:

  • Conviction or adjudication for a statutorily defined “sex offense”
  • Placement on probation, supervision, parole, or extended supervision for a qualifying offense
  • Commitment under certain mental health or sexually violent person statutes
  • Registration in another state followed by residence, employment, or school attendance in Wisconsin
  • Placement on lifetime supervision

Registration is not limited to Wisconsin convictions. Out-of-state, federal, military, and tribal convictions may also trigger Wisconsin registration if the offense is considered comparable to a Wisconsin sex offense.

Offenses That Trigger Registration in Wisconsin

Wisconsin law defines “sex offense” broadly. Registration may be required for convictions – or attempts, conspiracies, or solicitations – involving offenses such as:

Wisconsin courts may order sex offender registration for certain non-enumerated offenses under Wis. Stat. § 973.048(1m) – such as fourth degree sexual assault – if the court finds that the underlying conduct was sexually motivated and that registration is necessary to protect the public.

Mandatory vs. Court-Ordered Registration

Registration obligations arise in two primary ways:

Mandatory Registration

For many offenses, the court is required to order registration at sentencing unless the defendant qualifies for a narrow statutory exception, such as the underage sexual activity exemption.

Discretionary (Court-Ordered) Registration

In other cases, the court may impose registration if it finds:

  • the conduct was sexually motivated, and
  • registration is necessary in the interest of public protection.

This discretionary authority allows registration to be imposed even when the underlying conviction is not itself labeled a “sex offense.”

Duration of Registration Obligations

Registration is not always permanent, but it is often long-term. Depending on the offense and circumstances, registration may last:

  • 15 years after completion of a sentence or supervision, or
  • Lifetime, including cases involving multiple qualifying offenses, certain serious sexual offenses, or a court-ordered lifetime requirement.

Some individuals may petition for relief from registration after meeting statutory criteria. Others are barred from relief entirely.


Exceptions, Relief, and Removal From the Registry

Wisconsin law provides limited exceptions and relief mechanisms, including:

  • Underage sexual activity exceptions
  • Court-ordered determinations that registration is not required
  • Expungement or reversal of the underlying conviction
  • Statutory relief after a defined registration period in qualifying cases

Relief is not automatic. In most cases, the burden rests on the registrant to prove eligibility, often through a formal court process.


Why Registration Issues Require Early Legal Analysis

Sex offender registration decisions often occur at sentencing, but their consequences extend far beyond the criminal case. Registration affects housing, employment, travel, and daily life—and violations carry felony exposure.

Early legal analysis can determine:

  • whether registration is mandatory or discretionary,
  • whether statutory exceptions apply,
  • whether registration can be challenged or limited,
  • and how to avoid future registry violations.
