How the Kansas Juvenile Justice Authority Determines if a Minor is Tried as an Adult

Current as of: October 11, 2026 Juvenile Crime Defense Kansas
If your child is facing severe charges in Kansas, prosecutors may file a motion to prosecute them as an adult. Under Kan. Stat. Ann. § 38-2347, a judge decides the waiver. Fighting this transfer is critical to keeping the case in juvenile court.

When a minor is arrested for a severe crime in Kansas, parents often assume the case will automatically remain in juvenile court. However, prosecutors have the power to request that a minor be tried as an adult. This process, known as a waiver or adult certification, fundamentally changes the stakes. If certified as an adult, a teenager faces adult prison time rather than rehabilitation. Finding an experienced local lawyer from our US Attorneys directory who understands the Kansas juvenile system is critical. Whether you are in Olathe, Wichita, or Topeka, a strong legal defense can mean the difference between a second chance and a permanent adult criminal record.

Step-by-Step Process in Kansas Courts

In Kansas, juvenile cases are handled by the district courts, such as the Johnson County District Court, Olathe or the Sedgwick County District Court, Wichita. The process to transfer a minor to adult court involves strict procedural steps.

Step 1: The Prosecutor's Motion

The process begins when the county prosecutor files a motion requesting adult prosecution under Kan. Stat. Ann. § 38-2347. This motion must outline the specific reasons why the juvenile system is inadequate for the minor. The juvenile must generally be 14 years of age or older at the time of the alleged offense for this motion to be considered.

Step 2: The Waiver Hearing

A waiver hearing is scheduled before a district court judge. This hearing acts as a mini-trial. The prosecutor presents evidence to argue that the minor should be tried as an adult, while your defense attorney fights to keep the case in the juvenile system. The judge weighs statutory factors, including the severity of the offense, the minor's previous record, and the availability of juvenile treatment programs.

Violent Offenses Triggering Automatic Reviews

Not all crimes lead to a waiver hearing. In Kansas, specific severe offenses trigger an aggressive push by prosecutors. Offenses like first-degree murder, rape, aggravated robbery, or crimes committed with a firearm heavily influence the prosecution's decision to seek adult certification. However, under Kan. Stat. Ann. § 38-2347(a)(1), every juvenile is statutorily presumed to be a juvenile, and the state must rebut this presumption by a preponderance of the evidence based on eight statutory factors. A defense attorney can present compelling mitigating evidence showing that, despite the charge's severity, the minor is amenable to rehabilitation within the juvenile justice system.

The Role of the Kansas Juvenile Justice Authority (JJA)

The former Kansas Juvenile Justice Authority (JJA) was abolished in 2013, with its administrative responsibilities transferred to the Kansas Department of Corrections - Juvenile Services, Topeka. Crucially, no state executive agency decides whether a youth is tried as an adult; that decision rests exclusively with a District Court judge under Kan. Stat. Ann. § 38-2347. Today, KDOC Juvenile Services administers juvenile correctional facilities and community supervision programs. During a waiver hearing, the judge evaluates whether these facilities offer adequate rehabilitative programs before the youth reaches the statutory jurisdictional limits under Kan. Stat. Ann. § 38-2365 and Kan. Stat. Ann. § 38-2304-which allow confinement in a juvenile correctional complex up to age 22.5 and community supervision up to age 23.

How Psychological Evaluations Impact the Judge's Decision

A major component of a waiver hearing is the minor's psychological profile. A defense attorney will often request a comprehensive psychological evaluation to prove the teenager lacks adult maturity, has developmental delays, or has suffered severe trauma. Under precedents like State v. Jones, 273 Kan. 756 (KS Supreme Court 2002), the court must heavily weigh the juvenile's mental capacity and amenability to treatment. A favorable psychological report is one of the strongest tools to block a transfer to adult court.

The "Once an Adult, Always an Adult" Rule in KS

Kansas law applies a strict "once an adult, always an adult" rule. If a juvenile is successfully waived to adult court and convicted, any future criminal charges they face-even if they are still under 18-will automatically be processed in the adult criminal justice system. This makes the initial waiver hearing incredibly high-stakes, as losing it strips the child of juvenile court protections for the rest of their youth.

How Much Does it Cost to Fight an Adult Waiver?

Defending against an adult waiver requires a massive amount of legal work.

  • Attorney Fees: Retaining a specialized juvenile defense lawyer for a severe felony often requires a flat fee or retainer ranging from $5,000 to $15,000.
  • Psychological Evaluations: Hiring an independent forensic psychologist to testify on your child's behalf usually costs between $2,000 and $5,000.
  • Court Costs: Filing motions and securing subpoenas typically incurs a few hundred dollars in administrative fees.

How Long Does the Process Take?

A waiver hearing is usually scheduled within 30 to 60 days after the prosecutor files the motion. However, defense attorneys frequently request continuances to gather school records, medical history, and psychological evaluations. Because of this, the final decision on whether the minor will be tried as an adult in Kansas can take 3 to 6 months.

Frequently Asked Questions (FAQ)

What is the minimum age to be tried as an adult in Kansas?

Under Kan. Stat. Ann. § 38-2347, a juvenile must generally be at least 14 years old to be prosecuted as an adult.

Can the decision to waive a juvenile be appealed?

Generally, an adult certification cannot be immediately appealed. The juvenile must go through the adult trial process, and if convicted, they can appeal the original waiver decision at that time.

Does an adult waiver mean an automatic prison sentence?

No. Being tried as an adult simply means the case is held in adult court with adult sentencing guidelines. The minor still has the right to a trial, and the prosecutor must still prove guilt beyond a reasonable doubt.

Will my child be held in an adult jail before trial?

In most cases, even if waived to adult court, federal and state laws require minors to be housed separately from adult inmates, typically remaining in a juvenile detention facility until they turn 18.
