Michigan rape laws do not actually use the word “rape.” The state prosecutes sexual offenses under a four-tier framework called Criminal Sexual Conduct (CSC), and the degree charged depends on the type of act, the victim’s age, and whether aggravating factors were present. Penalties run from up to two years in prison for fourth-degree CSC to life for first-degree CSC, and every degree can trigger sex offender registration, with the most serious cases also carrying mandatory lifetime electronic monitoring.
Penetration Versus Contact
Which degree of CSC applies turns first on what kind of act occurred. “Sexual penetration” covers intercourse, oral sex, anal intercourse, or any intrusion of a body part or object into another person’s genital or anal opening, however slight. Emission of semen is not required.1Michigan Legislature. MCL – Section 750.520a
“Sexual contact” reaches further than many people expect. It includes intentional touching of intimate parts, or the clothing over them, when the touching can reasonably be interpreted as being for sexual arousal, gratification, revenge, humiliation, or anger.1Michigan Legislature. MCL – Section 750.520a Because revenge and humiliation are on that list, conduct that isn’t sexual in the ordinary sense can still qualify.
First- and third-degree CSC address penetration. Second- and fourth-degree CSC address contact. Within each pair, aggravating factors decide the degree.
The Four Degrees and Their Penalties
First-Degree CSC
First-degree CSC is Michigan’s most serious sexual offense. It requires sexual penetration plus at least one aggravating circumstance: the victim is under 13, the offender is armed, the offender causes physical injury while using force or coercion, or the act occurs during another felony such as a kidnapping or home invasion.2Michigan Legislature. MCL – Section 750.520b – Criminal Sexual Conduct in the First Degree
The penalty is life in prison or any term of years. When the victim is under 13 and the offender is 17 or older, the judge must impose at least 25 years.2Michigan Legislature. MCL – Section 750.520b – Criminal Sexual Conduct in the First Degree A repeat offender 18 or older who targets a child under 13, having previously been convicted of certain CSC offenses against a child under 13, faces life without parole.3Michigan Courts. First-Degree Criminal Sexual Conduct
Second-Degree CSC
Second-degree CSC pairs sexual contact with the same kinds of aggravating factors that elevate first-degree cases: a victim under 13, force or coercion, an armed offender, or another felony in progress.4Michigan Legislature. MCL – Section 750.520c – Criminal Sexual Conduct in the Second Degree
It is a felony carrying up to 15 years in prison, and offenders must register as sex offenders.4Michigan Legislature. MCL – Section 750.520c – Criminal Sexual Conduct in the Second Degree When the offender is 17 or older and the victim is under 13, lifetime electronic monitoring is mandatory.5Michigan Legislature. MCL – Section 750.520n
Third-Degree CSC
Third-degree CSC covers sexual penetration without the aggravating factors required for first-degree. The most common scenario is penetration with a person who is at least 13 but under 16. The statute contains no age-gap requirement, so a person can be charged regardless of how close in age they are to the younger person.6Michigan Legislature. Michigan Code 750.520d – Criminal Sexual Conduct in the Third Degree
Third-degree CSC also applies when force or coercion is used to accomplish penetration with an adult, when the victim is mentally incapable of consent, or when the offender holds a position of authority over a student between 16 and 18, or a person between 16 and 26 receiving special education services.6Michigan Legislature. Michigan Code 750.520d – Criminal Sexual Conduct in the Third Degree The penalty is up to 15 years in prison, with mandatory registration.
Fourth-Degree CSC
Fourth-degree CSC is the only degree charged as a misdemeanor. It involves sexual contact without the aggravating circumstances that would elevate a case to second-degree. A common example is sexual contact with a person at least 13 but under 16 when the offender is five or more years older, or sexual contact accomplished through force or coercion.7Michigan Legislature. Michigan Code 750 – Criminal Sexual Conduct in the Fourth Degree
The penalty is up to two years in prison, a fine of up to $500, or both.7Michigan Legislature. Michigan Code 750 – Criminal Sexual Conduct in the Fourth Degree Registration may still apply, and the conviction leaves a permanent criminal record.
Age of Consent
Michigan’s age of consent is 16. Sexual penetration with anyone under 16 can be prosecuted as third-degree CSC regardless of whether the younger person appeared willing, because the law treats anyone under 16 as unable to consent to penetration.6Michigan Legislature. Michigan Code 750.520d – Criminal Sexual Conduct in the Third Degree
The rules operate differently for contact and penetration. Fourth-degree CSC (contact) requires the offender to be at least five years older than a 13-to-15-year-old victim, which limits exposure for teens close in age.7Michigan Legislature. Michigan Code 750 – Criminal Sexual Conduct in the Fourth Degree Third-degree CSC (penetration) has no such age gap in the statute, so a 16-year-old is technically chargeable for penetration with a 15-year-old.
The effective age of consent rises to 18 for students in relationships with teachers or school employees, and to 26 for individuals receiving special education services when the offender is in a position of authority.6Michigan Legislature. Michigan Code 750.520d – Criminal Sexual Conduct in the Third Degree
Statute of Limitations
First-degree CSC has no statute of limitations. Prosecutors can bring charges at any time, no matter how many years have passed.8Michigan Legislature. MCL – Section 767.24 Second-, third-, and fourth-degree charges are subject to Michigan’s general criminal time limits.
A civil lawsuit seeking money damages for harm caused by criminal sexual conduct must be filed within 10 years, and a criminal conviction is not required to sue.9Michigan Legislature. MCL – Section 600.5805
Defenses
Which defenses are available depends almost entirely on which elements the prosecution must prove.
Consent in Force-Based Cases
When a charge rests on force or coercion, the defendant can raise consent as an affirmative defense. The theory is that a genuinely consensual encounter negates the force or coercion element. Michigan courts have recognized that a willing act between people of sufficient age who are not incapacitated is not criminal sexual conduct under the force-based provisions.10Michigan Courts. Consent
Consent is not a defense when the charge is based on the victim’s age, mental incapacity, or physical helplessness. In those cases, the law treats the victim as unable to consent regardless of what they said or did.
Mistake of Age
A defendant cannot escape an age-based CSC charge by arguing they genuinely and reasonably believed the victim was old enough. Michigan’s age-based CSC offenses are strict liability crimes: the prosecution only has to prove the victim’s actual age, not the defendant’s knowledge of it.11Michigan Courts. Mistake of Fact A fake ID, a lie about age, or an older appearance makes no legal difference. The Michigan Supreme Court has said the Legislature could have written a “knows or has reason to know” requirement into the age statutes and chose not to.
Rape Shield Law
Michigan’s rape shield statute sharply limits what a defendant can introduce about a victim’s sexual history. Evidence of past sexual conduct, whether specific instances or reputation evidence, is generally inadmissible.12Michigan Legislature. MCL – Section 750.520j
Two narrow exceptions exist: past sexual conduct between the victim and the defendant specifically, and sexual activity that explains the source of semen, pregnancy, or disease. Even then, the judge must find that the evidence is relevant and that its value outweighs any prejudicial effect.12Michigan Legislature. MCL – Section 750.520j
Registration and Lifetime Monitoring
Anyone convicted of a CSC offense in Michigan must register under the Sex Offenders Registration Act. Registration applies to people who live, work, or attend school in Michigan after conviction, and to people who move to Michigan with an out-of-state sex offense conviction.13Michigan Legislature. MCL – Section 28.723 Federal tiers under SORNA determine how long registration lasts and how often a registrant must appear in person, ranging from 15 years with annual verification up to lifetime registration with quarterly verification.14eCFR. Part 72 Sex Offender Registration and Notification
For first- or second-degree CSC committed by someone 17 or older against a child under 13, the court must also impose lifetime electronic monitoring. Tampering with or failing to maintain the device is itself a felony punishable by up to two years in prison and a $2,000 fine.5Michigan Legislature. MCL – Section 750.520n
Life After a Conviction
The sentence is only the beginning. A CSC conviction carries lasting restrictions on rights and daily life.
Firearms
Any felony CSC conviction triggers a permanent federal ban on possessing firearms or ammunition. Federal law prohibits gun possession by anyone convicted of a crime punishable by more than one year in prison.15Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts First-, second-, and third-degree CSC all clear that threshold, and even fourth-degree, at up to two years, exceeds it.
Housing
Public housing authorities must deny admission to any household containing someone subject to lifetime sex offender registration. The housing authority runs criminal background checks in the state where the housing sits and in any other state where household members have lived.16eCFR. 24 CFR Part 960 Subpart B – Admission Private landlords typically run their own checks, and sex offense records commonly lead to rental denials.
International Travel
Registered sex offenders must give advance notice before traveling outside the United States. Under the International Megan’s Law, the Angel Watch Center reviews travel records to identify registered offenders who have not given notice and may alert destination countries.17Office of the Law Revision Counsel. Chapter 215 – Advanced Notification of Traveling Sex Offenders
DNA Collection
Convicted sex offenders must provide DNA samples that are entered into the FBI’s Combined DNA Index System (CODIS). Profiles can be matched against DNA evidence from unsolved crimes, and a database match can establish probable cause for further investigation.18FBI. CODIS and NDIS Fact Sheet
Employment
Sex offense convictions routinely disqualify people from work involving children, vulnerable adults, law enforcement, education, and healthcare. Beyond formal bars, most employers run background checks, and a CSC record often makes hiring unlikely even in fields with no specific legal prohibition.
