Unlawful Sexual Activity with a Minor (Ages 14–15) in Utah

Posted by Stone River Criminal Defense Team

Last Updated: November 4, 2025

In Utah, sexual activity involving a 14- or 15-year-old can lead to serious criminal charges — even when both individuals believe the relationship is consensual. These laws are designed to protect minors from exploitation, but they can also apply in situations that feel far from criminal to those involved.

Teen relationships, age gaps, and unclear boundaries often lead to legal trouble. The law doesn’t always align with how people experience relationships — and once a report is made, the legal process moves quickly.

Who This Law Applies To

The charge applies when someone between the ages of 14 and 15 engages in sexual activity with someone older. Utah law says minors under 16 cannot legally consent to sexual activity, regardless of how mutual the interaction may seem.

The law makes some distinction based on age difference. If the age gap is small, penalties are lighter. But once the older person is 18 or older, the legal consequences can be harsher.

What Counts as Sexual Activity?

The law casts a wide net. Sexual activity isn’t limited to intercourse. It includes:

  • Sexual touching
  • Oral sex
  • Fondling
  • Any contact meant to arouse or gratify

In many cases, this also extends to digital behavior — such as sexting or sharing explicit images.

What Are the Penalties?

Penalties depend on the age gap and the nature of the contact:

If the older person is less than four years older:

If the older person is four or more years older:

  • Felony charges
  • Possible prison time (up to 5 years)
  • Sex offender registration in many cases

While judges and prosecutors have discretion, the statute leaves little room for leniency in more serious cases.

Common Scenarios

  • A 18-year-old in high school and a 15-year-old are in a relationship. This could result in a misdemeanor charge.
  • A 19-year-old has sex with a 15-year-old. Even if consensual, it’s likely treated as a felony.
  • A 21-year-old meets a 15-year-old online, believing they’re older. That could still lead to prosecution, with registration on the table.
  • A 15-year-old shares explicit photos with a 17-year-old, this could result in a felony charge.

In each case, consent isn’t a legal defense. The law is focused on age and conduct — not intentions or relationships.

What the Law Doesn’t Accept as a Defense

Some arguments might make sense emotionally — but they don’t work legally:

  • “They consented.”
  • “We were in a relationship.”
  • “They lied about their age.”
  • “Their parents approved.”

What to Do If You’re Involved in a Case

It’s important to avoid making statements, even informal ones. Texts, social media messages, and comments to friends can become key evidence.

Steps to take:

  1. Avoid communication with the minor involved.
  2. Preserve existing messages or records.
  3. Consult a criminal defense attorney with experience in these types of cases.

The earlier you understand your rights and the legal process, the better you can protect your options.

A Serious Charge with Lasting Impact

Unlawful sexual activity with a minor can carry long-term consequences — including a criminal record and possible registration as a sex offender. Even when the relationship is mutual, the law views age as the deciding factor.

Understanding how the statute works is a critical first step. Knowing what actions to avoid — and what to do if you’re under investigation — can make all the difference.
