  • cannot legally agree to have sexual intercourse
  • in Colorado.

Criminal Offenses

There are exceptions to this rule, including:

  • the "close in age" exception, and
  • marriage.

Colorado's age of consent is seventeen (17) under CRS 18-3-402.

1. What is the age of consent in Colorado?

The age of consent in Colorado is seventeen (17).1

This means that a person 17 years of age or older may consent to have sexual intercourse with any other person, regardless of age. A 17-year old could choose to engage in sexual intercourse with:

  • an 18-year old,
  • a 30-year old, or
  • a 90-year old.

Once a person reaches the age of 17, consensual sex is permitted with any other person who is also above the age of 17.

1.1 What is the purpose of the Colorado age of consent law?

The purpose of the law is to:

  • protect young individuals from sexual predators; and
  • to deter adults from seeking out sexual intercourse with Colorado's youth.

Younger children are not generally mature enough to understand the impacts of the decision to have sex, including:

  • unexpected pregnancy;
  • social stigma; and
  • sexually transmitted diseases.

2. Does it matter that the underage person wanted to have sex and consented?

No. Even if the sex is consensual, a person who engages in sexual intercourse with a person under the age of consent is guilty of a crime even if the other person consented to the sexual acts.

Often, criminal defendants will argue that not only did the underage person consent but that he or she offered and initiated the sexual encounter. This does not matter.

If the person is underage, he or she cannot legally consent, even if the underage person does consent.

2.1 What if I did not know the age of the person or the person lied about his or her age?

Many criminal defendants argue they did not know the age of the person, but this is no defense. This is true even when the person lies about his or her age.

Under Colorado law, defendants's knowledge or lack of knowledge of the other person's age does not matter.

3. Are there certain exceptions to the law in Colorado?

Certain exceptions exist to the age of consent laws in Colorado, but they are very specific and limited.

3.1 What is the "close in age" exception?

The close in age exception to the age of consent law recognizes that those who are close in age should not necessarily be charged with sex crimes due to a legal consent question. This is also referred to as the "Romeo and Juliet" law.

A young person who:

  • is under the age of 15
  • can choose to have sexual intercourse
  • with a person who is within 4 years of his or her age.2

Example: Claire is 14 and chooses to have sex with Anthony, who is 17. Though she is below the technical age of consent, because Anthony is within 4 years of her age, they can choose to engage in sexual intercourse. If instead, Anthony was 21, he could be charged criminally, as Claire is too young to consent to have sex with him.

If the person is between the ages of 15 but under 17:

  • he or she can consent
  • to engage in sexual intercourse
  • with a person who is within 10 years of his or her age.3

This means that a person who is 16 years old could consent to have sex with someone who is 25 years old because the older person is not more than 10 years older than the younger person.

3.2 Is there an exception for married couples in Colorado?

Those individuals who are legally married can consent to sexual intercourse with one another. The marriage must be a legal, valid marriage in order to qualify for this exception.

You must be 18 years of age or older to get married in Colorado, with the following exceptions:

  • at age 16 with the consent of both parents or the legal guardian; or
  • judicial approval if a person under the age of 16 wishes to be married, along with the consent of both parents or the legal guardian.4

If a person under the age of consent is legally married, even when the age difference is above 10 years, that person can legally consent to have sex with his or her spouse.

4. What is statutory rape?

Statutory rape is a term which means that someone had sex with another person who was not old enough to give legal consent.

CRS 18-3-402 defines the offense of sexual assault, which is the language used to describe statutory rape and forcible rape charges in Colorado. It involves:

  • any sexual intrusion
  • or sexual penetration
  • on a victim without consent.

This includes instances where a person is not able to give legal consent, such as those who are too young. Penalties differ depending on the age of the offender and the "victim."

5. What is sexual assault on a child?

The charge of sexual assault on a child is a closely related offense to statutory rape. If a person:

  • engages in sexual contact
  • with a person under the age of 15
  • and the actor is at least 4 years older than the victim

he or she can be charged with this offense.5 While less serious than a statutory rape charge, it still has serious criminal penalties.

6. How do I defend myself against these charges?

Colorado judges are aware that there are people who are wrongly accused, and there are legal defenses which can be used to defend you against criminal charges.

  • Age of Consent: You can argue and prove that the individual was actually of age to consent, and did consent to the sexual encounter.
  • No sexual conduct or contact occurred: You can show that no sexual encounter ever occurred between yourself and the alleged "victim."
  • False Accusations: Not all people accused of a crime by the supposed victim are guilty. Motivation to lie can be strong when a person feels spurned or rejected. There may even be components of revenge after a breakup, or some other reason the other person wants to get at you.
