Statutory rape in Colorado occurs when a person has penetrative sex with a minor under 17 years old, the legal age of consent. Even if no force is involved, statutory rape is prosecuted as sexual assault (18-3-402 C.R.S.). The only exceptions are if the people involved are married or near in age.
Depending on the case, statutory rape can be a felony or a misdemeanor. Felony convictions require the defendants to register as a sex offender. But it may be possible to get the charges reduced or dismissed through a plea bargain.

The age of consent in Colorado is 17 years old. People under 17 cannot legally consent to have sex. But there are some exceptions (explained below in section 3).1
The legal definition of statutory rape is sexual penetration or intrusion with someone who is under the age of 17. In Colorado, statutory rape is prosecuted as a type of sexual assault. It makes no difference if the sex itself was consensual.2
Sexual penetration or intrusion includes such sexual acts as:
- Intercourse (vaginal sex);
- Anal sex;
- Oral sex (fellatio, cunnilingus, anilingus); or
- Inserting fingers or objects into orifices
In many cases, the underage person never reports the incident. Instead, it is often the child’s parents, teachers, or jealous exes who notify the authorities.
Yes. There are two exceptions to the age of consent law in Colorado:
- The “close-in-age” exception, and
- The marriage exception
These Romeo and Juliet laws apply only to consensual sex. There is no close-in-age or marriage exception to forcible rape.
Children under 15 may legally consent to sex with people less than 4 years older. For example, a 14-year-old can have sex with a 17-year-old. This is because the older individual is not more than 4 years older.
Meanwhile, children aged 15 or 16 may legally consent to sex with people less than 10 years older. For example, a 16-year-old could consent to have sex with a 25-year-old. This is because the adult is less than 10 years older.
Married people may legally consent to have sex with their spouses. Their ages do not matter.3
The sentence for statutory rape depends on the age of the victim.
Statutory rape is a class 4 felony if:
- The victim was less than 15 years old, and
- The defendant is at least 4 years older than the victim,
The maximum penalty for a class 4 felony includes up to 8 years in Colorado State Prison and fines of up to $500,000.
Statutory rape is a class 1 misdemeanor if:
- The victim is at least 15 but less than 17 years old, and
- The defendant is at least 10 years older than the victim
Misdemeanor statutory rape is considered an extraordinary risk crime. Therefore, penalties include up to 24 months in jail and fines of up to $5,000.4
People convicted of felony sexual assault must register as sex offenders. Felony sex offenders’ names are publicly searchable on the Colorado Bureau of Investigation’s Sex Offender Registry.
Misdemeanor sexual assaults are not listed on the sex offender registry. But subsequent misdemeanor convictions may be listed.
Sex offenders have to register with the local chief of police or county sheriff. This includes providing their:
- Date of birth,
- Place of employment,
- Email addresses, and
- Instant messaging or chat room identities
Sex offenders must re-register every year within 5 days of their birthday. They also have to re-register if they move or start work at an institution of higher education.
Sexual assault convictions also subject the defendant to lifetime supervision.5
Two common arguments for fighting statutory rape charges are:
- No sexual penetration or intrusion occurred, or
- The defendant was falsely accused
The evidence in these cases typically comes down to “he said/she said” testimony. There are rarely video recordings or eyewitness accounts. This could make it difficult for the prosecutor to prove guilt beyond a reasonable doubt.
Verbal consent is not a defense. It does not matter if the victim instigated the sex. Underage people may not legally consent to sex.
Mistake of fact is also not a defense: It makes no difference if the victim lied about being 17 or looked like an adult. Statutory rape is a strict liability crime and can be sustained even if the defendant believed the other person was of age.
Sexual assault on a child (18-3-405 C.R.S.) is similar to statutory rape. But it does not require sexual penetration. Instead, it requires knowingly subjecting a child to “any sexual contact” if:
- The victim is less than 15 years old, and
- The defendant is at least 4 years older than the victim
Sexual assault of a child is typically a class 4 felony. But it becomes a class 3 felony if the defendant used either:
- Threats, or
- Threat of retaliation
A conviction requires registering as a sex offender.
Incest (18-6-301 C.R.S.) occurs when someone knowingly marries or has sexual contact with a family member. “Family” includes a:
- Natural or adopted child,
- Step-child at least 21 years old,
- Whole-blood or half-blood sibling,
- Niece, or
- Any ancestor or descendant
Incest is a class 4 felony carrying sex offender registration.
Internet exploitation of a child (18-3-405.4 C.R.S.) is using the internet to encourage a child to masturbate or to watch the defendant masturbate. Internet exploitation of a child is a class 4 felony carrying sex offender registration.
