Missouri Megan’s Law: Registration, Residency, and Penalties

Missouri’s Megan’s Law requires people convicted of qualifying sex offenses to register in person with their county sheriff, keep that registration current for a set number of years or for life, and follow residency and conduct restrictions tied to schools, child care facilities, and Halloween. The rules sit mainly in §§ 589.400 through 589.426 of the Missouri Revised Statutes, and the registry itself is run by the Missouri State Highway Patrol.1Missouri Revisor of Statutes. Missouri Code 589.400 – Registration of Certain Offenders With Chief Law Officers of County of Residence

Who Has to Register

Registration applies to anyone convicted of, who pleaded guilty to, or who was found guilty of a qualifying sexual offense at any point since July 1, 1979. Attempts and conspiracies count. The qualifying offenses are broad: rape, sodomy, child molestation and other Chapter 566 offenses, sexual abuse or exploitation of a child, child pornography, incest, promoting prostitution, and kidnapping of a child by someone other than a parent or guardian.1Missouri Revisor of Statutes. Missouri Code 589.400 – Registration of Certain Offenders With Chief Law Officers of County of Residence2Justia. Missouri Code Chapter 566 – Sexual Offenses

A conviction isn’t the only trigger. People found not guilty by reason of mental disease or defect for a qualifying offense must register, as must anyone committed to the Department of Mental Health as a criminal sexual psychopath.

If you move to Missouri from another state, from federal, tribal, or military jurisdiction, you must register here when your out-of-state offense is substantially similar to a Missouri registerable offense. That holds even if the state you came from didn’t require you to register.

What the Sheriff Collects

You register in person at the office of the chief law enforcement officer in your county of residence, which in most places is the county sheriff. Under § 589.407, you provide a signed written statement with your name, residential address, date of birth, Social Security number, and phone number. The office collects fingerprints, palm prints, a current photograph, and a DNA sample if one is not already on file.3Missouri Revisor of Statutes. Missouri Code 589.407 – Registration, Required Information

You also report where you work and where you go to school, plus the year, make, model, color, and license plate of every vehicle you own or operate. And you report your online identifiers, meaning the email addresses, social media accounts, and similar digital handles defined in § 43.651. Lying on the form or leaving required details out is itself a criminal violation.

Registration is a continuing duty. Any time your address, employer, school, vehicle, or online identifiers change, you have three business days to appear in person at the sheriff’s office and update your record.4Missouri Revisor of Statutes. Missouri Code 589.414 – Registrants Duties on Change of Information If you move to another state entirely, you notify both your old Missouri jurisdiction and the new one within the same three business days.

How Long You Register and How Often You Check In

Missouri uses a three-tier system modeled on the federal Sex Offender Registration and Notification Act. Your tier is set by the registration official based on the offense you were convicted of, cross-referenced to the lists in § 589.414. It isn’t negotiable, and it controls both the length of your registration and how often you have to verify your information in person.

  • Tier I: fifteen-year registration period, with one in-person verification each year during your birth month. After the required waiting period, you may petition for removal.
  • Tier II: twenty-five-year registration period, with in-person verification every six months, once during your birth month and once six months later.
  • Tier III: lifetime registration, with in-person verification every ninety days. Removal is generally unavailable unless the underlying offense was a juvenile adjudication.5Missouri Revisor of Statutes. Missouri Code 589.401 – Removal From Registry, Petition, Procedure

Where You Can Live and Where You Can Go

Registration brings geographic limits on top of the reporting rules. Section 566.147 prohibits certain offenders from living within 1,000 feet of the property line of a school, a child care facility, or the victim’s residence. Violating that residency rule is a separate crime.6Missouri State Highway Patrol. Sex Offender Registry Fact Sheet

Section 566.149 adds a presence rule. Offenders convicted of Chapter 566 offenses or related child exploitation crimes cannot enter a school building, be within 500 feet of school grounds, or ride on a school bus or other vehicle used to transport students when anyone under 18 is present.7Missouri Revisor of Statutes. Missouri Code 566.149 – Certain Offenders Not to Be Present Within Five Hundred Feet of School Property There is one narrow exception for a parent or legal guardian of a student, who may obtain written permission from the superintendent, the school board, or (for private schools) the principal. Permission must be secured for each event or series of events. A violation is a class A misdemeanor whether or not the offender knew they were inside the restricted zone.

Halloween Rules

October 31st carries its own conduct code. Under § 589.426, every registered sex offender must:8Missouri Revisor of Statutes. Missouri Code 589.426 – Halloween, Restrictions on Conduct

  • Avoid all Halloween-related contact with children.
  • Stay inside their residence between 5:00 p.m. and 10:30 p.m., unless there is a legitimate reason to be elsewhere, such as work or a medical emergency.
  • Turn off all outside residential lighting after 5:00 p.m.

The statute also required a posted sign reading “No candy or treats at this residence,” but a 2024 federal court decision in Sanderson v. Bailey struck that sign requirement down as compelled speech under the First Amendment. The rest of the Halloween rules remain in force, and violating them is a class A misdemeanor.

Getting Off the Registry

Missouri does not take anyone off the registry automatically. You have to petition the court under § 589.401, and the court will dismiss the petition on sight if the minimum waiting period has not run.5Missouri Revisor of Statutes. Missouri Code 589.401 – Removal From Registry, Petition, Procedure

  • Tier I: ten years from the date registration was required for your most recent offense.
  • Tier II: twenty-five years.
  • Tier III based on a juvenile adjudication: twenty-five years. Tier III based on an adult conviction: no removal available.

Clearing the waiting period only gets you in the door. The court must also find that you have no pending charges and no convictions for any felony or any additional registerable sex offense since the date you were required to register at your current tier, that you completed every term of supervised release, probation, or parole without revocation, that you completed an approved sex offender treatment program, and that you do not pose a current or potential threat to public safety.

If the court denies your petition because of a disqualifying conviction, you must wait an additional fifteen years (Tier I) or twenty-five years (Tier II or juvenile Tier III) from the date of that conviction before you can file again. If your original conviction was in another jurisdiction, you have to seek removal there first, then register an authenticated copy of the removal order in your Missouri county.

Penalties for Failing to Register

Under § 589.425, the penalty for a registration violation depends on both the count and the seriousness of the underlying sex offense.9Missouri Revisor of Statutes. Missouri Code 589.425 – Failure to Register, Penalty

  • First offense: a class E felony, punishable by up to four years in prison. The charge becomes a class D felony (up to seven years) when the underlying registration offense was a Chapter 566 unclassified felony, a class A or B felony, or any felony involving a child under fourteen.10Missouri Revisor of Statutes. Missouri Code 558.011 – Imprisonment Terms
  • Second offense: the same class E or class D structure applies. A repeat charge does not automatically escalate; the seriousness of the original sex offense still controls.
  • Third or subsequent offense: a mandatory prison sentence of ten to thirty years, regardless of the underlying offense.

These penalties cover every form of noncompliance, not just a failure to register in the first place. Missing a verification appointment, failing to report a change of address within three business days, and leaving required information off the form all fall under the same statute.

What the Public Can See

The Missouri State Highway Patrol runs a free online database that anyone can search by name, zip code, or a radius around an address. Under § 589.402, public records on each registrant include name and known aliases, date of birth, physical description, residence, temporary, work, and school addresses, photographs, vehicle descriptions, the nature and dates of qualifying offenses along with the tier level, the release or supervision start date, and current compliance status.11Missouri Revisor of Statutes. Missouri Code 589.402 – Internet Search Capability of Registered Sex Offenders Social Security numbers and other sensitive law enforcement data stay private. Online identifiers are not shown on the public profile; a member of the public can only check whether a specific username matches a registrant by entering it into the search tool.
