At Wayman Law Group, we represent juveniles and their families throughout the St. Louis area, including St. Louis City, St. Louis County, St. Charles County, and Jefferson County, as well as Metro East Illinois including Madison and St. Clair County. We understand what is at stake, and we fight to protect your child's record, their rights, and their future.
The juvenile justice system in Missouri operates under Chapter 211 of the Missouri Revised Statutes. It was designed with rehabilitation in mind, not punishment. That distinction matters, but it does not mean the process is easy or that the outcome is guaranteed. A delinquency adjudication is not the same as a criminal conviction, but it can still result in probation, commitment to the Missouri Division of Youth Services (DYS), and in serious cases, transfer to adult court where your child faces the same consequences as any adult defendant.
How Does the Missouri Juvenile Justice System Work?
Missouri juvenile court has exclusive original jurisdiction over any child alleged to have violated state law or a municipal ordinance before turning eighteen. That authority comes from Mo. Rev. Stat. § 211.031. Unlike adult criminal court, the case is not brought by a prosecutor. A juvenile officer files a petition, and the hearing is decided by a judge alone. There is no jury in juvenile court.
The terminology is different from adult court by design. Your child is not charged with a crime. They are accused of a delinquent act. If the court finds the allegations proven, your child is not convicted. They are adjudicated delinquent. The outcome is a disposition, not a sentence. That distinction preserves your child's ability to move forward without a permanent criminal record in most cases.
At the adjudication stage, the rules of evidence apply in full. The juvenile officer must prove every element of every alleged offense beyond a reasonable doubt. The Missouri Supreme Court confirmed this standard under the constitutional framework established by In re Winship, and Missouri courts apply it consistently. That means there is a real defense to be made, and the burden stays with the state throughout.
What Happens at the Different Stages of a Missouri Juvenile Case?
A juvenile case can move through several stages depending on the seriousness of the offense and the juvenile officer's decision about how to handle it.
Before any petition is filed, the juvenile officer has the authority to resolve the matter through what Missouri calls an informal adjustment. This is an agreement between the juvenile, the family, and the juvenile officer to address the behavior without formal court proceedings. Common conditions include counseling, community service, restitution, or regular check-ins. If the juvenile completes those terms, the case closes without any court record.
When an informal adjustment is not appropriate, the juvenile officer files a formal petition in juvenile court. A detention hearing must follow within 24 hours if the child is being held, and a full detention hearing must occur within three days under Mo. Rev. Stat. § 211.061. At the adjudication hearing, the court hears evidence and determines whether the state has met its burden of proof. If the child is found delinquent, a separate dispositional hearing follows to determine the appropriate outcome.
What Are the Possible Outcomes in Missouri Juvenile Court?
Missouri law gives the juvenile court a wide range of options when it comes to disposition. Under Mo. Rev. Stat. § 211.181, the court can choose from the following:
-
Supervision in the home under court-ordered conditions
-
Probation, which can be unsupervised or supervised by a probation officer
-
Placement with a relative, foster family, or licensed agency
-
Commitment to the Missouri Division of Youth Services (DYS)
-
Counseling, mental health evaluation, or treatment programs
-
Community service
-
Restitution to any victim (must be reasonable given the juvenile's ability to pay)
-
Driver's license suspension
-
Individualized treatment plans developed with family participation
DYS commitment is the most serious outcome available in juvenile court. The court can set a minimum period of commitment, but no order can require a child to remain in DYS custody beyond their nineteenth birthday unless DYS petitions the court for an extension. For most juveniles, this time-limited structure gives the defense something to work with: we can advocate for programming that is specifically tailored to your child's needs and argue against the most restrictive options.
Can a Child Be Tried as an Adult in Missouri?
Yes. Missouri law allows juveniles to be transferred to adult court through a process called certification. If your child is certified and later convicted as an adult, the juvenile court loses jurisdiction over them permanently for any future offense. This is one of the most serious consequences in the entire juvenile justice system, and it requires immediate legal action.
When Is Certification Required or Possible Under Missouri Law?
Mo. Rev. Stat. § 211.071 governs certification to adult court. There are two tracks.
Discretionary certification applies when a petition alleges that a child between 14 and 18 committed an act that would be a felony if committed by an adult. In those cases, the court may, in its discretion, order a certification hearing.
Mandatory certification hearings are required when the allegations involve a child between 12 and 18 and one of the following enumerated serious offenses: first-degree murder (§ 565.020), second-degree murder (§ 565.021), first-degree assault (§ 565.050), rape in the first degree (§ 566.030), sodomy in the first degree (§ 566.060), first-degree robbery (§ 570.023), manufacturing a controlled substance (§ 579.055), any dangerous felony as defined in § 556.061, any felony involving a deadly weapon, or two or more prior felony-equivalent adjudications.
A mandatory hearing does not guarantee certification. The court must evaluate ten non-exclusive factors before deciding whether to transfer the case. Those factors include the seriousness of the offense, whether violence or force was involved, the child's prior record, their maturity and sophistication, whether they can benefit from programs available through the juvenile court, and notably under § 211.071.6(10), racial disparity in certification rates. Certification decisions are reviewed on appeal under an abuse of discretion standard.
Missouri courts have recognized that seriousness of the offense is the dominant factor in the certification analysis, but the law requires a holistic look at all ten factors. Defense counsel must commission independent psychological and developmental evaluations, present specific evidence of available DYS programs, and make the case that rehabilitation is achievable within the juvenile system's timeframe. Certification is not inevitable, and we challenge it aggressively.
What Charges Do Missouri Juveniles Face Most Often?
Juveniles can be accused of the same offenses as adults, and the elements the state must prove are identical. Here is how Missouri law classifies the most common charges:
Assault Offenses
First-degree assault under Mo. Rev. Stat. § 565.050 requires an attempt to kill or knowingly causing or attempting to cause serious physical injury. In adult court, this is a Class B felony carrying five to fifteen years, elevated to a Class A felony (ten to thirty years or life) if serious physical injury is actually inflicted or the victim is a special victim as defined in § 565.002. Second-degree assault under § 565.052 covers a range of conduct including knowingly causing physical injury with a deadly weapon and recklessly causing serious physical injury. Third-degree assault under § 565.054, requiring only that someone knowingly cause physical injury, is a Class E felony in adult court.
First-degree robbery under Mo. Rev. Stat. § 570.023 is a Class A felony in adult court. It requires forcible stealing of property combined with one aggravating factor: serious physical injury, being armed with a deadly weapon, using or threatening a dangerous instrument, or displaying what appears to be a deadly weapon. It also triggers a mandatory certification hearing for juveniles ages twelve through eighteen. Second-degree robbery under § 570.025, requiring physical injury during a forcible theft, is a Class B felony.
Drug and Weapons Charges
Possession of most controlled substances under Mo. Rev. Stat. § 579.015 is a Class D felony in adult court. Small amounts of marijuana carry misdemeanor classifications. Unlawful use of weapons at school under Mo. Rev. Stat. § 571.030.1(10) applies when a juvenile knowingly carries a firearm or weapon readily capable of lethal use into a school, onto a school bus, or at a school-sponsored activity. Armed criminal action under § 571.015 is an unclassified felony carrying a mandatory minimum three-year prison term consecutive to any other sentence. It applies whenever a felony is committed by, with, or through use of a deadly weapon or dangerous instrument, and it is a dangerous felony that triggers mandatory certification consideration.
What Rights Does My Child Have During a Police Investigation or Interrogation?
Missouri provides juvenile-specific protections that go beyond the standard Miranda warning that applies to adults. Under Mo. Rev. Stat. § 211.059, before any questioning, a juvenile in custody must be advised both orally and in writing of the following: the right to remain silent, that any statement can be used against them in juvenile proceedings, the right to have a parent or guardian present during questioning, the right to consult with an attorney with appointment if they cannot afford one, the right to stop answering at any time, and that any statement can also be used against them in adult court if they are later certified.
The juvenile officer must also tell your child that the juvenile officer is not their attorney and is not advocating for them during the interrogation. If the juvenile asks to stop, questioning must cease immediately. Missouri courts have held that failure to strictly comply with § 211.059 makes any resulting statement inadmissible at the adjudication hearing. This is a meaningful protection, and it is one of the first things we evaluate in any case.
Beyond the statutory requirements, courts look at the totality of circumstances to evaluate whether a statement was voluntary. That includes your child's age, education, intelligence, experience, and whether a parent was present. The absence of a parent does not automatically make a statement inadmissible, but it is a significant factor, and we will use it.
What About Searches at School? Can Evidence Be Suppressed?
Yes, under the right circumstances. Missouri applies the reasonable suspicion standard to searches conducted by school officials. That standard comes from the U.S. Supreme Court's decision in New Jersey v. T.L.O. and has been applied consistently by Missouri appellate courts. In State v. Williams, 521 S.W.3d 689 (2017), the Missouri Court of Appeals held that a student's tardiness alone does not create reasonable suspicion for a pat-down search, and a blanket policy authorizing suspicionless searches of all late-arriving students was unconstitutional.
Individualized reasonable suspicion tied to your specific child is required before a school official can search their person or belongings. If that standard was not met, any evidence found in that search may be suppressible. School resource officers who are acting in a law enforcement capacity may be held to the higher probable cause standard rather than the reduced reasonable suspicion standard applicable to school administrators, though Missouri courts have not fully settled this question.
What Happens to My Child's Record? Can It Be Sealed or Expunged?
Juvenile court records in Missouri are generally confidential under Mo. Rev. Stat. § 211.321. They are not open to the public. After a child turns eighteen, the court may enter an order to seal the official court file and destroy social histories and records if it finds doing so is in the child's best interest.
One important exception: if a juvenile is adjudicated delinquent for an act that would be a felony if committed by an adult, the records of the dispositional hearing and related proceedings become open to the public to the same extent as adult criminal records. This is a significant consequence that strengthens the case for fighting the underlying adjudication or, where adjudication is unavoidable, pursuing the least serious dispositional outcome.
For cases resolved through informal adjustment, the record typically closes without a formal adjudication. For formal adjudications involving misdemeanor-equivalent acts, a petition to seal the record may be filed after the juvenile has been discharged from court jurisdiction, completed all sentence conditions, remained offense-free, and at least two years have passed since completing their sentence.
How Is Juvenile Court Different From Adult Criminal Court in Missouri?
Wayman Law Group handles a high volume of expungement matters annually across Missouri and can evaluate your child's eligibility as part of the overall case strategy.
The differences matter practically and legally. In adult court, a prosecutor files charges through an indictment or information. In juvenile court, the juvenile officer files a petition. In adult court, a defendant has the right to a jury. In juvenile court, the judge decides everything. Neither the U.S. Constitution nor the Missouri Constitution requires a jury trial in juvenile delinquency proceedings, as Missouri courts have confirmed.
In adult court, a conviction is permanent unless it is later expunged through a formal petition process. In juvenile court, the language itself reflects a different philosophy: the child is found delinquent, not convicted; they receive a disposition, not a sentence. Those distinctions are meaningful for background checks, employment, and future proceedings, though they disappear entirely if the child is certified and convicted as an adult.
Despite these differences, the constitutional protections that attach at the adjudication stage are substantial. Your child has the right to notice of the specific charges, the right to counsel (which cannot be waived at certification hearings, contested felony detention hearings, or adjudication hearings on felony offenses under Mo. Rev. Stat. § 211.211), the right to confront and cross-examine witnesses, and the protection against self-incrimination. Double jeopardy protection also applies in delinquency proceedings.
Why Does It Matter Which Attorney You Hire for a Juvenile Case?
Juvenile court has its own procedural rules, its own evidentiary standards at different hearing stages, and its own approach to strategy. The rules of evidence apply in full at adjudication hearings. They do not apply at dispositional hearings. Certification hearings allow hearsay. These distinctions shape how we build your child's defense at each stage.
Missouri courts have reversed adjudications where children were found guilty of offenses not actually charged in the petition, because adjudication on an uncharged offense that is not a lesser-included offense violates due process. Courts have reversed DYS commitments where judges accepted a juvenile's admissions without making the required on-record findings of voluntariness and factual basis. Courts have reversed adjudications where statements were obtained in violation of § 211.059. These are not obscure technicalities. They are the foundations of a meaningful defense.
