Illinois’s Statutory Rape Laws and Potential Penalties

Aggravated criminal sexual abuse. Under Illinois’s laws, a defendant commits the crime of aggravated criminal sexual abuse by engaging in sexual conduct (such as sexual touching or fondling) with:

  • a child under 13 years old when the defendant is 17 or older
  • a child under nine years old when the defendant is under age 17,
  • a child under 18 years old, when the defendant is a family member,
  • a child who is at least 13 and younger than 18 years old, when the defendant is at least 17 and in a position of trust, authority, or supervision over the child, or
  • a child who is at least 13 years of age, but under 17 years old, when the defendant is more than five years older than the victim.

Aggravated criminal sexual abuse also includes sexual penetration (vaginal, oral, or anal sex) between a child who is at least 13 years old, but younger than 17 years old, and a defendant who is more than five years older than the victim.

Aggravated criminal sexual abuse is a Class 2 felony. Potential penalties include three to seven years in prison, a fine of $25 up to $25,000, or both.

(720 Ill. Comp. Stat. 5/11-0.1, 5/11-1.60, 5/5-4.5-35, 5/5-4.5-50 (2018).)

Child Enticement in Illinois

Asking a child to engage in sexual activity or arranging to meet a child without the permission of the child’s parents can result in child enticement charges.

Defenses to a Statutory Rape Charge in Illinois

There are some important defenses to consider in statutory rape cases.

Mistake as to the Victim’s Age

In many states, it is never a defense to a charge of statutory rape that the defendant believed the victim to be of age. However, Illinois law provides a limited defense in some circumstances.

It is a defense to a charge of criminal sexual abuse that the defendant believed a child between the ages of 13 and 16 to be 17 years old or older. It is also a defense to a charge of criminal sexual abuse that a defendant under the age of 17 believed a child to be over the age 17. In both situations, the defendant must have a good reason to believe the child is over the age of 17. (720 Ill. Comp. Stat. 5/11-1.70 (2018).)

If, for example, the defendant knew that the child was in middle school, the defendant would probably not be able to show that he or she reasonably believed the child to be over 17.

The “Romeo and Juliet” Exception

Named after the lovers in Shakespeare’s play, “Romeo and Juliet” exceptions protect youngsters who engage in sexual contact with people close to their own age from serious criminal charges.

In Illinois, there is a limited Romeo and Juliet exemption for criminal sexual abuse. The conduct is still illegal, but someone protected by this exception will face the possibility of smaller fines and reduced jail time than someone who is charged with felony sexual assault or abuse. (720 Ill. Comp. Stat. 5/11-1.50 (2018).)

Marriage

In many states, a person cannot be convicted of statutory rape of their spouse, but marriage provides no defense in Illinois. For more information on spousal rape and the historic marital rape exemption, see our article on marital rape laws.

Sex Offender Registration

Under Illinois law, people who are convicted of sexual assault or sexual abuse are required to register as sex offenders. (730 Ill. Comp. Stat. 150/2, 150/3 (2018).)
