Failure to Register as a Sex Offender – The Law in Colorado – C.R.S. § 18-3-412.5

C.R.S. § 18-3-412.5 makes it a crime to fail to comply with Colorado’s sex offender registration requirements. Depending on the underlying unlawful sexual behavior, failure to register can be a misdemeanor or a felony.

Some registrants appear in the Colorado Bureau of Investigation (CBI) public database.

Common Violations:

• Missing a registration deadline,
• Submitting false or incomplete information, or
• Failing to report a required change.

Registration Information:

• Your current and former names, including aliases, and date of birth;
• Your residential addresses or, if you lack a fixed residence, locations where you can be found or habitually sleep;
• Your place of employment and applicable postsecondary school enrollment, employment, or volunteer locations;
• A current photograph and fingerprints;
• Identifying information for motor vehicles you own or lease; and
• Email addresses, instant-messaging identities, and chat room identities if you are subject to the child-sex-crime requirements in C.R.S. § 16-22-108(2.5), subject to a qualifying employment-email exception.

Registration Schedule:

• First-time registration: Within five business days after release from incarceration or after receiving notice of the duty if you were not incarcerated. If discharged from prison without supervision, you must register by the next business day.
• Annual registration: Most registrants must reregister within five business days before or after their birthday.
• Quarterly registration: Sexually violent predators (SVPs), adults convicted of specified offenses, and certain out-of-state registrants must reregister every three months, within the statutory five-business-day window.
• If no fixed residence: In addition to regular registration, annual registrants must verify their locations at least every three months, and quarterly registrants must do so at least monthly.
• Moving residences: You generally must register your new address within five business days after leaving your old address. Additional residences and other required changes also trigger reporting duties.¹

1. Penalties

Colorado’s penalties for failing to register as a sex offender under C.R.S. 18-3-412.5 turn on your underlying sex offense. The more serious the sex crime, the more serious the penalties for failure to register, as discussed below.

Misdemeanor Failure to Register

In Colorado, failure to register as a sex offender is a class 1 misdemeanor if you were convicted of a misdemeanor sex offense or its equivalent in another jurisdiction or juvenile court. For offenses committed on or after March 1, 2022, the punishment carries:

• Up to 364 days in jail and/or
• A fine of up to $1,000.²

Felony Failure to Register

Failure to register as a Colorado sex offender is a class 6 felony when the underlying case involves felony unlawful sexual behavior, including qualifying felony-level juvenile adjudications. The presumptive sentencing range is:

• 1 to 1.5 years in prison and/or
• A fine of $1,000 to $100,000.

For a person in this felony-level category, a second or subsequent failure to register is a class 5 felony, carrying:

• 1 to 3 years in prison and/or
• A fine of $1,000 to $100,000.³

These are presumptive prison ranges; aggravating circumstances can increase the sentence. Probation may be available, and a prison sentence also carries a period of mandatory parole.

Juvenile Failure to Register

When failure to register is handled as a juvenile delinquency case rather than an adult criminal prosecution, C.R.S. § 18-3-412.5(4) provides:

• First misdemeanor-level violation: A mandatory minimum of 30 days in juvenile detention.
• Second or subsequent misdemeanor-level violation: A mandatory minimum of 45 days in juvenile detention.
• First felony-level violation: A mandatory minimum of 45 days in juvenile detention.
• Second or subsequent felony-level violation: Out-of-home placement or commitment for at least one year. This is not necessarily one year in a juvenile detention facility.⁴

Failure to Verify a Location

If you lack a fixed residence, failing to complete the additional location verification required by C.R.S. § 16-22-109(3.5)(c) is a separate offense under C.R.S. § 18-3-412.6.

For offenses committed on or after March 1, 2022, it is a class 2 misdemeanor carrying up to 120 days in jail and/or a $750 fine. The statute makes people convicted of this offense ineligible for probation.

Other failures to comply with registration duties may still be prosecuted under C.R.S. § 18-3-412.5.⁵

2. Defenses

It is an affirmative defense to Colorado charges of failure to register as a sex offender when all three of the following are true:

1. Uncontrollable or emergency circumstances prevented you from complying; and
2. You did not contribute to these uncontrollable circumstances in reckless disregard of your requirement to register; and
3. You complied as soon as the circumstances ceased to exist.

For instance, if the reason you did not register was that you were comatose in the hospital after being rear-ended by another driver, you should not be convicted of failure to register. Another potential defense would be proving that you did, in fact, comply, but the government made a clerical error or otherwise failed to record your compliance.

To raise the uncontrollable circumstances defense to a failure to register charge, you must notify the prosecutor as soon as practicable and no later than 35 days before trial. The separate failure-to-verify-location statute uses a 30-day deadline. Homelessness alone does not excuse registration.⁶

Our defense team can investigate registration receipts, agency records, medical evidence, and the notices you received to challenge the charge.

3. Forgetting To Register

In People v. Lopez, the Colorado Court of Appeals held that failure to register required proof that the defendant acted knowingly. However, that does not mean saying “I forgot” automatically establishes a defense.

Knowledge and intent are different legal concepts, and prosecutors do not necessarily have to prove that you deliberately set out to break the law. The specific charge, your registration notices, and the surrounding facts matter.⁷

We can review what you were told, your registration history, and the evidence of the alleged violation to determine how best to craft your defense.

4. Moving To Colorado

If you are required to register and move to Colorado from another state, you generally must register with local law enforcement in each jurisdiction where you reside within five business days. Colorado’s requirements can apply even if your obligation in the original state has ended.

Federal SORNA duties apply separately to people covered by that law. Federal regulations generally require reporting a residence change in person within three business days and advance reporting of an intended move to another jurisdiction. You must also comply with applicable requirements in the state you are leaving.⁸

Before a move, we recommend confirming the requirements with both jurisdictions and keeping copies of every registration and notification. Meeting one deadline does not guarantee compliance with all state and federal duties.

5. Moving From Colorado

When you move from Colorado to another state, Colorado law requires you to file a written registration cancellation form with the law enforcement agency for your old address within five business days after you stop residing there. The form must identify the old address and all addresses where you will reside.

Separately, federal SORNA regulations require covered registrants to report an intended residence change to another jurisdiction before leaving and generally report the residence change in person within three business days. You must also satisfy the destination state’s registration requirements.⁹

We recommend arranging the reporting steps before your move and retaining written proof. Moving away does not erase an existing registration obligation or resolve an outstanding failure to register charge.

6. Early Removal

Some people can petition to discontinue sex offender registration under C.R.S. § 16-22-113. Eligibility depends on the offense, sentence, subsequent record, and applicable exceptions. The ordinary waiting periods are:

• Five years: Eligible misdemeanor offenses other than class 1 misdemeanor unlawful sexual contact and the corresponding former offense of third-degree sexual assault.
• Ten years: Eligible class 4, 5, or 6 felonies, plus class 1 misdemeanor unlawful sexual contact and the corresponding former offense.
• Twenty years: Eligible class 1, 2, or 3 felonies that are not subject to a lifetime-registration bar.

These periods do not simply run from your first registration. Depending on the sentence and statutory category, they run from discharge from the department of corrections or department of human services, or final release from the court’s jurisdiction. Subsequent convictions involving unlawful sexual behavior can disqualify you.

Special rules may permit earlier relief following successful completion of a deferred judgment and dismissal of the case, or completion of a qualifying juvenile sentence. Certain juvenile registration duties terminate automatically under C.R.S. § 16-22-103(4). A separate exception allows petitions based on severe physical or intellectual disability causing permanent incapacity when the statutory public-safety requirements are met.

Lifetime registration is generally mandatory for SVPs and adults convicted of specified offenses, including:

• sexual assault,
• sexual assault on a child,
• sexual assault on a child by a person in a position of trust,
• sexual assault on a client by a psychotherapist, or
• incest, and aggravated incest.

Multiple qualifying adult convictions, or an adult conviction combined with a qualifying juvenile adjudication, can also bar ordinary removal.

Petitioning for Removal

For a Colorado conviction, you generally file for early removal from the sex offender registry in the court that entered the judgment. For an out-of-state conviction, the statute permits a civil petition in the district court where you reside. Use the Colorado Judicial Branch’s current forms and instructions for your situation.

Send a copy of the petition by certified mail to:

• Every law enforcement agency with which you must register;
• The district attorney for the jurisdiction where you filed the petition; and
• The prosecutor who obtained your conviction.

Within 21 days after filing, file copies of the return receipts and supporting eligibility documents, including available records of completion of court-ordered treatment. An objection by the district attorney or victim requires a hearing; without an objection, the court may decide the petition without one.

Approval depends on the statutory findings, including:

• completion of the sentence,
• expiration of the applicable waiting period,
• absence of disqualifying subsequent convictions, and
• whether you are likely to commit another offense involving unlawful sexual behavior.

If the court grants relief, provide the order to each registering law enforcement agency and the CBI. Continue registering unless your duty has legally ended.¹⁰

Our attorneys can evaluate your eligibility, calculate the relevant dates, and assemble treatment and court records to support your petition.

7. Registrable Sex Crimes

Colorado registration law covers specified unlawful sexual behavior and certain offenses whose underlying facts involve unlawful sexual behavior. Examples include the following:

• Enticement of a child (C.R.S. 18-3-305) – luring a child under 15 into a vehicle, building, room, or secluded place to commit sexual assault or unlawful sexual contact on them.
• Indecent exposure (C.R.S. 18-7-302) – specified knowing genital exposure for sexual arousal or gratification, or knowing masturbation, under circumstances likely to cause affront or alarm.
• Internet luring of a child (C.R.S. 18-3-306) – specified electronic sexual communications with someone you know or believe is under 15 and at least four years younger, combined with persuading or inviting that person to meet. The subsection (3) form involves intent to engage in sexual exploitation or sexual contact.
• Pandering a child (C.R.S. 18-7-403) – arranging or offering to arrange child prostitution for money or something of value, or inducing it through menacing or criminal intimidation.
• Pimping a child (C.R.S. 18-7-405) – knowingly living on a child prostitute’s earnings.
• Sexual assault / rape (C.R.S. 18-3-402) – non-consensual penetrative sex.
• Sexual assault of a child by one in a position of trust (C.R.S. 18-3-405.3) – sexual touching of a child by a caregiver, medical provider, teacher, or other person with supervisory authority over the child.
• Sexual exploitation of a child (C.R.S. 18-6-403) – possessing, producing, or distributing child pornography (“child sexual abuse material” or CSAM).
• Solicitation of a child prostitute (C.R.S. 18-7-402) – arranging a meeting for the purpose of trading sex acts for money.
• Unlawful sexual contact (C.R.S. 18-3-404) – non-consensual sexual touching such as groping or fondling.

Frequently Asked Questions

How soon must I register after release from jail or prison?

The usual Colorado deadline is five business days after release from incarceration for the offense requiring registration. If you are discharged from a state department of corrections without supervision, the deadline is the next business day. If you were not incarcerated, the general deadline is five business days after notice of the duty to register.

What happens if I forget to register?

You can still face charges. A lawyer may challenge whether prosecutors can prove the mental state required for your specific alleged violation, but ordinary forgetfulness is not an automatic defense. Registration notices, prior compliance, and the circumstances of the missed deadline can affect the case.

What are the penalties for failure to register?

For offenses committed on or after March 1, 2022, misdemeanor-level failure to register is a class 1 misdemeanor carrying up to 364 days in jail and/or $1,000.

A felony-level first offense is a class 6 felony with a presumptive prison range of one to 1.5 years and a $1,000 to $100,000 fine. A repeat felony-level offense is a class 5 felony with a presumptive range of one to three years and the same fine range.

Probation may be available; aggravating circumstances and mandatory parole can affect the sentence.

What must I do before moving out of Colorado?

Plan for both state and federal requirements. Colorado requires a written cancellation form within five business days after you stop residing at your old address.

Federal SORNA rules require covered registrants to report an intended interstate residence change before leaving and generally report a residence change in person within three business days. You must also meet the destination state’s requirements.

Do I have to register if I am homeless?

Yes. You must register even without a fixed residence and identify locations where you can be found or habitually sleep. In addition to regular registration, annual registrants must verify their locations at least every three months; quarterly registrants must do so at least monthly.

Failure to complete this additional verification is a class 2 misdemeanor carrying up to 120 days in jail and/or $750 for offenses committed on or after March 1, 2022, and probation is unavailable for that offense.

Does the five-business-day deadline include weekends and holidays?

No. Weekends and legal holidays are not business days. However, some obligations have a different deadline, including next-business-day registration after an unsupervised discharge from a state department of corrections.

Contact the registering agency promptly to confirm its registration hours and the deadline that applies to you.

Must I register my email addresses and online identities?

Under Colorado’s C.R.S. § 16-22-108(2.5), people convicted of specified child sex crimes must register email addresses, instant-messaging identities, and chat room identities before using them. A qualifying employer-provided email address is exempt.

The state requirement does not apply identically to every registrant; federal SORNA or supervision conditions may impose additional duties.

Can I petition to stop registering in Colorado?

Some people qualify after statutory waiting periods of five, ten, or twenty years.

Class 1 misdemeanor unlawful sexual contact generally falls in the ten-year category. The periods run from the discharge or final release specified by law, not simply from initial registration.

Lifetime-registration bars apply to certain cases, while special rules address deferred judgments, juveniles, and permanent incapacity.

Do not stop registering merely because a waiting period has passed.
