Wisconsin Sexual Assault Laws: Consent, Charges, Penalties, and Reporting
Meta description: Learn how Wisconsin sexual assault laws define consent, classify offenses, set penalties, address age-related cases, and explain reporting and victim support options.
Wisconsin sexual assault laws cover a range of conduct, from nonconsensual sexual contact to serious assaults involving force, injury, or an incapacitated person. The legal classification depends on what happened, the people involved, and the circumstances. Knowing the basic rules can help people understand potential charges, reporting options, and where to find support. This overview summarizes key Wisconsin statutes, but it is general information—not legal advice. Laws and procedures can change, and a Wisconsin attorney can assess how they apply to a specific situation.
How Wisconsin Defines Sexual Assault
Wisconsin’s primary criminal sexual assault statute is Wis. Stat. § 940.225. It divides sexual assault into four degrees. The degree generally reflects the type of sexual conduct and factors such as force, injury, the person’s ability to consent, and age.
The statute distinguishes sexual intercourse from sexual contact. Intercourse includes specified forms of penetration and oral sexual conduct. Sexual contact generally involves intentional touching for sexual arousal or gratification, or in a manner done for sexual humiliation or degradation. The legal definitions are detailed, so the precise conduct matters.
Wisconsin law defines consent as words or actions from a person competent to give informed consent that indicate a freely given agreement to sexual intercourse or contact. Silence or lack of physical resistance does not automatically establish consent. A person can withdraw consent, and agreement to one activity does not necessarily mean agreement to another.
Under § 940.225, consent is absent in circumstances that include force or violence, certain threats, unconsciousness, and a physical or mental condition that prevents the person from understanding the nature of the conduct. The statute also addresses situations involving people who are under the legal age for the relevant offense. Whether consent existed is a fact-specific question; investigators and courts consider evidence and the statutory rules.
The Four Degrees Of Sexual Assault
The following overview is a simplified guide to the degree structure in § 940.225. A prosecutor selects charges based on the available evidence, and a court determines guilt under the applicable legal standard.
| Degree | General description | Maximum classification |
|---|---|---|
| First-degree sexual assault | Sexual assault involving specified aggravating circumstances, such as great bodily harm, use or threat of a dangerous weapon, or certain assaults against a person unable to consent. | Class B felony |
| Second-degree sexual assault | Sexual assault involving circumstances listed in the statute, including certain force, threats, or situations in which the person is unconscious or otherwise unable to consent. | Class C felony |
| Third-degree sexual assault | Sexual intercourse with a person without that person’s consent, when a more serious degree does not apply. | Class G felony |
| Fourth-degree sexual assault | Sexual contact with a person without that person’s consent, when a more serious degree does not apply. | Class A misdemeanor |
These summaries do not capture every statutory element or exception. For example, the law treats some assaults involving age, custody, supervision, or a person’s condition differently. A case may also involve more than one charge, or charges under other statutes in addition to § 940.225.
Penalties And Other Legal Consequences
Possible criminal penalties depend on the offense classification, a person’s criminal history, sentencing rules, and the case’s circumstances. Wisconsin’s general maximum penalties are set out in Wis. Stat. § 939.50 for felonies and Wis. Stat. § 939.51 for misdemeanors.
- Class B felony: A maximum of 60 years of imprisonment.
- Class C felony: A maximum of 40 years of imprisonment.
- Class G felony: A maximum of 10 years of imprisonment.
- Class A misdemeanor: A maximum of 9 months in jail and a $10,000 fine.
These are statutory maximums, not predictions of a sentence in an individual case. Felony sentences may include confinement and extended supervision, and a court may impose other lawful conditions. A conviction can also affect employment, housing, professional licensing, immigration status, and personal relationships. The consequences depend on the offense and the person’s circumstances.
Some people convicted of qualifying sexual offenses must register under Wisconsin’s sex offender registration law, Wis. Stat. § 301.45. Registration requirements depend on the offense and other legal factors; they do not apply identically to every case. Registration can require reporting identifying information and updates to the Wisconsin Department of Corrections. A defense attorney can explain whether a specific conviction triggers registration and what duties would follow.
Age, Minors, And Related Offenses
Sexual conduct involving a person under 18 can raise legal issues beyond the general assault statute. Wisconsin’s child sexual assault provisions appear in Wis. Stat. § 948.02, while other statutes address conduct such as sexual exploitation, exposing a child to harmful material, and certain relationships of authority or supervision.
Wisconsin has distinct rules for children under 16 and for some conduct involving people who are 16 or older. For example, Wis. Stat. § 948.09 addresses sexual intercourse with a child who is 16 or older in specified circumstances, including an age difference defined by the statute. Other provisions may apply depending on the conduct and the relationship between the people involved.
Because age-related statutes contain specific elements and exceptions, it is risky to assume that a particular age difference or relationship makes conduct lawful. The relevant statute, the parties’ ages, the type of conduct, and any authority relationship can all matter. Cases involving minors should be reviewed with a Wisconsin attorney familiar with the applicable criminal law.
Reporting Sexual Assault In Wisconsin
A person who has experienced sexual assault may report it to local law enforcement, a county sheriff’s office, or another appropriate agency. Calling 911 is an option when there is immediate danger or an urgent need for emergency assistance. Reporting is not the same as deciding whether to pursue every available legal option, and a victim advocate can explain what to expect.
Medical care can address injuries, assess health concerns, and provide access to a sexual assault forensic examination. A person does not have to decide immediately whether to make a police report in order to seek medical attention. Forensic evidence may be time-sensitive, so a hospital or sexual assault service can explain available options and evidence-collection procedures. The person should avoid delaying urgent care.
Evidence may include medical records, messages, photographs, clothing, or details about the incident. A survivor should not be blamed for washing, changing clothes, or waiting to report; those actions do not make an assault less serious. If it feels safe, preserving relevant messages and writing down details can help later, but a person’s immediate safety and well-being come first.
In Wisconsin, the Department of Justice Office of Crime Victim Services provides information about victim services and compensation. The RAINN National Sexual Assault Hotline is available at 800-656-HOPE (4673) and through online chat. Emergency services should be contacted for immediate danger.
Time Limits And The Criminal Process
Wisconsin criminal statutes of limitation vary by offense and can depend on when the alleged conduct occurred and the age of the person involved. Some offenses have special rules or exceptions. The general limitation statute is Wis. Stat. § 939.74, but it should not be used to estimate a deadline without checking the provisions that apply to the specific charge.
A criminal case typically begins with an investigation. Law enforcement may interview people, gather records, and seek physical or digital evidence. A prosecutor then decides whether to file charges. If charges are filed, the case may proceed through an initial appearance, preliminary hearing for certain felonies, arraignment, motions, and potentially a trial or plea resolution. The exact process depends on the charges and the court.
A person accused of sexual assault has the right to legal representation and should avoid discussing case details publicly or with investigators without first getting legal advice. A person reporting an assault may also seek an advocate or attorney to understand privacy, safety, and participation options. The roles of the prosecutor, defense lawyer, victim advocate, and court are different.
How Wisconsin Sexual Assault Law Differs From Civil Claims
A criminal prosecution is brought by the government and can result in penalties such as incarceration, fines, or registration when legally required. A civil lawsuit is a separate legal action that may seek compensation for losses. The legal standards, procedures, and time limits can differ, and a criminal case does not automatically resolve whether a civil claim is available.
Potential civil claims and deadlines depend on the facts, the defendant, the claimant’s age, and other legal rules. Anyone considering a civil case should consult a Wisconsin attorney promptly, because limitation periods and notice requirements may apply. A victim advocate can help connect someone with legal resources, but an advocate is not a substitute for legal advice.
Finding Reliable Information And Legal Help
For current statutory language, the Wisconsin Legislature’s official online statutes are the most direct source. The Wisconsin Department of Justice provides victim-service information, and local law enforcement agencies can explain their reporting procedures. Court records and charging documents can provide case-specific information, but they do not replace advice from a qualified lawyer.
Wisconsin sexual assault laws turn on detailed definitions and facts, including the nature of the conduct, consent, age, capacity, and aggravating circumstances. The four-degree framework offers a starting point, not a substitute for reviewing the statute. For a specific incident or charge, a Wisconsin criminal defense attorney or victim-services professional can help explain available options and next steps.
