Child Sex Crime Sentencing in Colorado — What the Law Currently Says (and What Was Just Proposed)

In March 2026, a bill that would have stripped the probation option out of certain child sex assault cases stalled in a Colorado Senate committee. The proposal drew emotional testimony on both sides before it was postponed indefinitely, and it left a lot of people asking a fair question: what do Colorado child sex crime sentencing laws actually require right now?

The short answer is that these are among the most severe penalties in the state’s criminal code, and they work differently from almost every other offense. Here’s how the current framework operates, and what the 2026 proposal would have changed.

How Colorado Classifies Child Sex Offenses

Most child sex cases in Colorado are charged under one of two statutes. The first is sexual assault on a child, which applies when an adult subjects a child under 15 to sexual contact and is at least four years older. It’s normally a class 4 felony, but it becomes a class 3 felony when force, threats, or a pattern of abuse are involved.

The second covers the same conduct by someone in a position of trust, like a coach, teacher, relative, or caregiver. That offense is a class 3 felony when the child is under 15 or when there’s a pattern of abuse, and a class 4 felony when the child is 15 to 17.

Those felony classes set the starting point, but they don’t tell the whole story. The Colorado sex crime felony sentence range for these offenses isn’t a flat number of years the way it is for a theft or a DUI. Anyone facing these charges is looking at a sentencing structure built specifically for sex offenses, and it changes the math considerably.

What the Sentence Actually Looks Like

Colorado sentences most felony sex offenses under the Sex Offender Lifetime Supervision Act, passed in 1998. Instead of a fixed term, the court hands down an indeterminate sentence: a minimum number of years on the low end and the person’s natural life on the high end. A class 4 sexual assault on a child carries a low end of 2 years to life. A class 3 case driven by force or a pattern of abuse is treated as a crime of violence and carries a low end of 8 years to life.

So what is the minimum sentence for child sex crimes in Colorado? It’s the lower term the judge sets, which can’t dip below the presumptive minimum for that felony class. But the minimum only marks the earliest point someone can be considered for release, not a guaranteed exit. After the minimum term, the Parole Board decides whether to release the person, and it can keep someone in custody for the rest of their life if it considers them a continuing risk. That open-ended ceiling sets these sentences apart from the rest of the code.

Probation: When It's on the Table

Colorado sex crime probation eligibility is narrower than people expect, but it does exist for some offenses. Under the Lifetime Supervision Act, a judge may grant probation for certain sex crimes. When they do, probation is also indeterminate: a minimum of 10 years for a class 4 felony or 20 years for a class 2 or 3 felony, stretching up to life.

There are firm limits on when probation is available, though:

Crimes of violence are excluded: if the offense involves force or threats, the court must impose a prison sentence rather than probation.
Repeat child sex offenders are excluded: anyone eligible for sentencing as a habitual offender against children has to go to prison.
The youngest victims are carved out: when the offense involves penetration or intrusion against a child under 12 by an adult at least ten years older, prison is mandatory.

So, can someone convicted of a child sex offense get probation in Colorado? Sometimes, but only for offenses that fall outside those exclusions, and only after the court reviews a mandatory sex-offense-specific evaluation.

How does Colorado decide whether to allow probation in a sex crime case? The judge weighs that evaluation along with the statutory sentencing factors, the facts of the case, and input from prosecutors and victims. Probation here also comes with intensive supervision and mandatory treatment, so it’s far from a lenient outcome.

Sex Offender Registration and SORA

A conviction doesn’t end with the sentence. Sex offender registration in Colorado, governed by the state’s Sex Offender Registration Act (often shortened to SORA), requires people convicted of sex offenses to register their address, employment, and vehicle details with law enforcement, and adult felony offenders appear on a public database maintained by the Colorado Bureau of Investigation.

What does sex offender registration mean for someone convicted in Colorado? In practical terms, it shapes daily life long after any sentence ends:

“Most registrants re-register once a year, while sexually violent predators and people convicted of the most serious offenses re-register every 90 days. Many child sex offenses require lifetime registration, with no realistic path off the list. Failing to register is a separate felony that piles new charges on top of the original conviction.”

The 2026 Proposal: Senate Bill 26-111

That brings us back to the no-probation sex crimes bill that Colorado lawmakers debated in 2026. Senate Bill 26-111, titled “Protections Against Child Rape,” would have removed the probation option for certain class 3 and class 4 child sexual assault offenses that currently allow it. Under the bill, a class 4 sexual assault on a child or position-of-trust offense would have required an indeterminate prison term starting at 2 years, and a class 3 position-of-trust offense involving a child under 15 would have required a term starting at 4 years.

The measure had bipartisan sponsorship and followed several earlier attempts dating back to 2024. It fell short in the Senate Judiciary Committee on a 4-3 vote in March 2026, when the committee voted to postpone it indefinitely. Supporters argued that anyone who assaults a child should serve prison time rather than walk on probation.

Opponents, including some who testified, warned that a blanket rule would strip judges of discretion and sideline the recommendations of prosecutors and victims who sometimes ask for an outcome other than incarceration. For now, the existing framework stands, and probation remains available for the narrow set of offenses described above.

What's at Stake in a Child Sex Case

Few charges in Colorado carry consequences this lasting: an indeterminate sentence that can run for life, supervision and treatment requirements, and registration that can follow someone permanently. Because the stakes are so high, the details matter enormously, from how an offense is classified to whether a given case qualifies for probation at all.

A careful defense against child sexual abuse charges in Colorado, built on a close look at the evidence and strong mitigation, can change the trajectory of a case well before sentencing.
