Criminal Sexual Assault

Criminal Sexual Assault occurs when a person commits an act of sexual penetration against a victim under specific circumstances – through force or threat of force, when the perpetrator and the victim are related- whether through familial ties or a position of authority, or if there is an age gap with the victim being under the age of consent (age 17).  In just about any circumstance, a person who commits Criminal Sexual Assault will face a time behind bars, hefty fines and will have to register as a sex offender for a period of time.


The Illinois Statute (720 ILCS 5/11-0.1) outlines how this crime can be committed:

  • Contact – No matter how slight, between one person’s sexual organ, finger, hand or anus and another person’s sexual organ, anus, or mouth; or

  • Intrusion – No matter how slight, between a person, animal, or object and another person’s sexual organ or anus. 

Section 11-0.1 provides several examples of sexual penetration, including but not limited to fellatio, cunnilingus, and anal penetration. Criminal Sexual Assault does not require ejaculation or a similar emission of semen.

720 ILCS 5/11-1.20(b) provides a breakdown of the penalties for criminal sexual assault in Illinois. In most situations, the punishment for this offense depends upon the number of previous offenses, if any. 

  • First offense of Criminal Sexual Assault constitutes a Class 1 felony in Illinois. The punishment for a Class 1 felony can be anywhere from 4-15 years in prison. It can also result in up to 48 months of probation. 

  • Second or subsequent offense of Criminal Sexual Assault is a Class X felony in Illinois. Upon conviction, a sentence between 6-30 years in prison. Probation is not available for Class X felonies.

  • In certain circumstances, with a previously conviction of aggravated or predatory Criminal Sexual Assault, the punishment can be life in prison.

Even without prison time, a conviction will result in a felony record, and mandatory registration on the Sex Offender Registry, which impacts where a person can live and requires yearly registration. The names and addresses of registered sex offenders is available online to the public.
