A juvenile adjudication for robbery, arson, or an act involving serious bodily harm is included in the report that a judge reads before sentencing you as an adult. This requirement is written into Missouri’s juvenile records statute. “Confidential” is not the same as “gone”, and families usually find out the difference at the worst possible time.
The Protection Is Real, and It Is Narrower Than People Assume
A juvenile adjudication is not a criminal conviction under Missouri law. Court files are kept separate from adult records and are closed to the general public. These rules matter and they apply in most situations.
They also come with exceptions. A judge can open a file to anyone with a legitimate interest. Juvenile officers may share case information with prosecutors, police, school officials, and agencies involved in the care of a child. And once a child has been found guilty of conduct that would constitute a felony if committed by an adult, records of the hearing on disposition are open to the public in the same way that adult criminal records are.
Turning 18 doesn’t close the file. Nothing closes it by itself.
Where a Juvenile Record Reaches Into an Adult Case
Three channels come up over and over in practice:
Sentencing
When a pre-sentence report is ordered, Missouri law requires it to include juvenile adjudications for a specific set of offences: murder, rape, sodomy, kidnapping, robbery, arson, burglary and acts involving serious bodily harm or the threat thereof. Shoplifting at the age of 15 is not included on this list. However, a robbery conviction at the age 16 years is.
Charging and Bond
Prosecutors see the juvenile history well before sentencing, and this shapes what gets filed, what is offered, and how a judge decides about release.
The Next Juvenile Case
A child’s record and previous experience with the juvenile justice system are one of the factors a court considers when deciding whether to transfer a teenager to an adult court.
A New 2026 Law Changed What Gets Shared
Governor Kehoe signed Senate Bill 888 on April 7, 2026. Most of the bill takes effect on August 28, 2026, and there are several important parts.
Officers must now fingerprint individuals under 18 for certain felony offenses, and the old rule requiring fingerprint cards to keep a juvenile’s name out of the central repository has been repealed. Juvenile officers must share criminal history data with the Missouri Uniform Law Enforcement System, creating a statewide juvenile criminal history database available to law enforcement and criminal justice agencies. These records remain closed to the public, but they are much easier for police and prosecutors in Missouri to locate.
The same law narrows the discretionary certification of children 14 to 18 for Class A and B felonies, sexual offenses and three felony acts committed within 180 days. Prosecutors have also gained the authority to file their own motion for certification and present evidence to support it.
Certification Ends the Juvenile Protections Completely
If a case is transferred to adult court and the prosecution results in a conviction, there is no juvenile record left to protect. A public adult conviction is recorded, and the juvenile court’s jurisdiction over that child is permanently terminated. The confidentiality of police records does not apply to children who are transferred either.
Sealing Is Possible, but Someone Has to Ask
A court may order the destruction of social histories and seal official court files along with police records when a person turns 18. If sealing serves the best interests of the person, the court may act after the case has been closed.
Two things catch families off guard: sealing takes a motion or an application, so nobody gets it by waiting; and Missouri’s new automatic expungement program, signed into law in July 2026 and rolled out through the Highway Patrol, applies to certain adult drug convictions, but will not reach juvenile files.
Handle the Record Before Someone Else Uses It
The government devotes serious resources to charging people and securing convictions. As of this month, it has better tools for tracking what a 15-year-old did in another country. Your defense attorney stands between you and all that.
