When Can a Juvenile Be Tried as an Adult in California?

Written by Alison Cohen November 2, 2020; reviewed by Mathew Lanthier November 22, 2023.

As a criminal defense lawyer with a focus on juvenile delinquency, I get many questions about whether children can be tried as adults.

Can children be tried as adults?


The short answer is “yes”, but only when specific conditions are met.

Teens can be tried as adults if:
They are 16 or 17 years old on the date the alleged crime is committed

AND

they are charged with one or more felony offenses

AND

the prosecutor asks the court to transfer the case to adult court.

OR

They are at least 14 years old on the date the alleged crime is committed (children 13 and under cannot be charged as adults in California)

AND

The crime is listed in subdivision (b) of Welfare and Institutions Code section 707: murder (intentionally killing someone), robbery (using force to steal from someone), forcible sexual assault (rape), kidnapping (forcibly moving someone against their will), assault with a firearm (shooting someone), etc.

AND

They are not apprehended before they turn 21.

Why are some youth tried as adults?


The majority of 16 and 17-year-olds who come into court facing felony charges remain in juvenile court and are not tried as adults. The District Attorney must make a special motion asking the court to transfer a qualifying case into adult court.  This typically happens in two scenarios:

When children commit serious and/or violent crimes like rape, robbery, assault with a firearm, murder, etc.

OR

When children have a long history of committing felonies and seem incapable of being rehabilitated by the juvenile justice system.

For what crimes can juveniles be charged as adults?


California Welfare and Institutions Code section 707(b) lists specific crimes that qualify to be transferred to adult court, but any felony charge will qualify if the child was 16 or older at the time of the incident: 

Murder and attempted murder:  intentionally killing someone or trying to kill someone

Arson causing great bodily injury to someone:  intentionally burning a structure, forest land, or property and causing great bodily injury to someone in the process

Robbery:  Using force or threats to steal property off someone’s person

Forcible sexual assault:

• For purposes of robbery:  kidnapping for the purpose of stealing from the person

• With bodily harm: kidnapping that causes bodily harm to the victim

• For purposes of sexual assault: kidnapping for the purpose of raping the victim, for example

Exploding a destructive device with intent to murder:  exploding a bomb or other device with the intent to kill someone

Voluntary manslaughter:  driving with gross negligence that results in someone’s death, for example

How do children get to adult court?


When a case meets the criteria listed above, the District Attorney can make a motion to transfer the youth from juvenile court to adult court.  That motion is typically made at the first court appearance or soon thereafter.  At that point, the underlying case is put on hold.  In other words, the child cannot proceed to trial or plead guilty to the charged offenses until the court decides whether the case will proceed in juvenile court or be transferred to adult court. This process usually takes several months.

When a motion to transfer is made, the court will order the Probation Department to prepare a report on the behavioral patterns and social history of the child.  This report will include, among other things, a list of prior criminal offenses committed by the child, information provided by the child’s parents about behavior in the home, academic and disciplinary information from the school district, and any services previously provided to the child by Probation or the Court.

A hearing date will be set for the court to hear evidence from Probation, the District Attorney, and the minor’s counsel.  At that hearing, the court must consider the following criteria:

• The degree of criminal sophistication exhibited by the child when he/she committed the crime

• Whether the child can be rehabilitated prior to the expiration of the juvenile court’s jurisdiction (at 21 or 25 years old, depending on the crime)

• The child’s previous delinquent history

• Success of previous attempts by the juvenile court to rehabilitate the child

• The circumstances and gravity of the charges

The District Attorney has the burden to prove at the hearing that the case should be transferred to adult court.

Can a juvenile or minor be charged with a felony?


Yes. Any child over the age of 12 may be charged with a felony in California.

Children under the age of 12 may be charged only for extremely serious crimes like murder or rape. 

Even in felony cases, virtually all children are charged as children. 

The case still starts in juvenile court even if the DA wants to try your child as an adult. The DA has to file a transfer petition to move the case to adult court. Normally, the child must be at least 16 years old to get transferred to adult court, though sometimes the DA petitions to transfer a child as young as 14 over a very serious crime that goes undiscovered for a long period of time.

Either way, transferring a juvenile case to adult court is quite difficult. Under new changes to the law as of 2023, the DA must prove that there is no chance to rehabilitate the child within the juvenile system. 

Most children who are successfully transferred to adult court have extremely long juvenile records. If this is your child’s first offense for a minor crime, you have far less cause to worry than a parent whose child is a repeat, habitual offender accused of murder or rape.

What age can you be tried as an adult in California?


The youngest age you could be transferred to adult court is 14, but the DA must prove you cannot be rehabilitated in the juvenile system.

Trying children as adults is rare in California. It’s most likely in the following cases:

• Your child is found guilty of committing a serious crime like murder or rape.
• Your child is found guilty of committing assault with a deadly weapon or assault with means likely to cause serious bodily injury.
• Your child has a history of violating their probation, especially if they are over the age of 16.
• Your child has an extremely long juvenile record showing that the juvenile court has been unable to rehabilitate your child.

As your child’s defense lawyer, we would fight hard to keep them out of adult court if there is even a remote possibility that this could happen to them.

Can adults be charged with crimes they committed as minors?


Yes. In some scenarios, when someone commits offenses as a child that are discovered later, there is a chance the case could be transferred to adult court. If you are an adult facing this scenario, speak to one of our criminal defense attorneys immediately.

What happens if I’m charged as a juvenile and become an adult before conviction?


The juvenile case continues even if you turn 18. It’s very common for children to be charged at 17 and to turn 18 while the case is ongoing. In California, the juvenile court doesn’t lose jurisdiction until a person turns 21. In most cases, there is plenty of time to resolve the case in juvenile court before that happens. In some cases, juvenile court jurisdictions can extend well beyond age 21.

How can you prevent a juvenile from being tried as an adult?


Expert testimony is key to persuading a judge to keep a child in juvenile court. 

A psychologist or psychiatrist can evaluate the child to diagnose mental health issues, recommend treatment, and identify mitigating factors that support keeping the case in juvenile court: 

• lack of maturity

• lack of intellectual capacity

• impetuosity

• lack of an ability to understand risks and consequences of criminal behavior

• mental and emotional health problems at the time of the crimes

• the effect of familial, adult, or peer pressure on the child’s actions

• the effect of childhood trauma on the child’s criminal sophistication

An expert in corrections can identify rehabilitative services available through the juvenile justice system that the child will not receive if transferred to adult court:

• high school education

• substance abuse treatment

• appropriate counseling for childhood trauma

• protection from exploitation by adult inmates

These experts typically provide written reports that can be submitted to the court with a defense brief and can also testify at the transfer hearing.

What are the effects of juveniles being tried as adults?


There are many differences between the juvenile justice system and the adult criminal system.  Both systems aim to protect the safety of the public, but the adult system tends to be more punitive and the juvenile system is designed to rehabilitate the minor so that he or she can become a law-abiding and productive member of the family and of the community.  For instance:

• Juvenile adjudications do not count as criminal convictions and do not have to be disclosed on job applications.  Adult convictions are public record and must be disclosed.

• Youth in juvenile court do not spend time in state prison.  Youth convicted in adult court may be sent to the Division of Juvenile Justice or may be sentenced to serve time in state prison.

Can a juvenile go to jail?


No. Children under the age of 18 cannot go to jail. Jail is an adult facility. In some unusual cases, an 18-year-old that is on juvenile probation can go to jail. Thus, a 16-year-old or 17-7ear-old will not go to jail, nor will a child of 13, 14, or 15. 

Children of any age may go to juvenile hall, which is a secure facility run by the probation department. Juvenile hall is designed to house children involved in the juvenile court system. A child housed in juvenile hall will never mingle with convicted adults. 

Why should we not try juveniles as adults?


Developments in psychology and brain science over the years confirm what most parents know instinctively:  there are fundamental differences between juvenile and adult minds.  

Children are less able to control their behavior, appreciate long-term consequences, and stand up to peer pressure.  They are less likely to understand the abstract principles of the criminal justice system, making it more difficult for them to have meaningful participation in court proceedings that will impact their future. 

Because their brains are still developing, teenagers who engage in criminal behavior are likely to grow out of it, even without court intervention.  Studies show that most children charged with criminal offenses will commit far fewer offenses after they turn 25. Most kids who display bad behavior will grow out of it independently.

Transfer to adult court can entrench minors in a life of criminal behavior that they otherwise would have matured away from. Kids tried as adults learn crime from hardened adult criminals and leave the system with few prospects and little hope for the future. Being jailed with adults increases their risks of drug addiction. These children often become victims of sexual assault. At best, they see and hear things that are not age-appropriate. Trying juveniles as adults does not make anyone safer. It just ensures that the troubled child will become an adult with PTSD and a real risk of committing additional crimes. 

Children have different rehabilitative needs than adults. Because the brain changes so much during adolescence, appropriate intervention during these years can have a disproportionately positive impact on rehabilitation.  Conversely, a lack of appropriate treatment in adolescence can have a disproportionately negative impact on rehabilitation.  Children able to stay in the juvenile system have access to age-appropriate education and rehabilitative services that are designed for them.  Children transferred to the adult system may be subject to long sentences in adult prison where they are deprived of age-appropriate services and exposed to increased risk of physical, sexual, and self-harm.

Reasons Why Juveniles Should be Tried as Adults

As defense attorneys, we don’t believe there are any good reasons to try children as adults.

If the District Attorney believes that the child cannot be rehabilitated by the juvenile justice system, they may ask to move the case to adult court.  This happens most often in cases where the child is either charged with a serious crime like murder or has a long record of interactions with the juvenile justice system.

Recent real-world cases of juveniles facing transfer to adult court that were tried as juveniles

Teen with substance abuse problem tried as juvenile instead of adult

A 17-year-old with a severe substance abuse problem was placed in a group home.  He got swept up in a plan by other minors to steal a staff member’s car and escape.  In the process, the staff member was badly beaten.  Our client was charged with serious and violent felonies and the District Attorney moved to transfer him to adult court. By thoroughly reviewing his history, we determined that our client had been assessed as needing a significantly higher level of treatment than the group home could provide. The client was mentally and emotionally unwell and experiencing severe withdrawal at the time of the incident.  Childhood trauma left him emotionally and mentally immature and unable to make appropriate decisions under stress.  The court ultimately found that there were appropriate treatment options available through the juvenile justice system and elected not to transfer him to adult court.

Manipulated 17-year-old girl tried as juvenile instead of adult

A 17-year-old girl was dating a man in his forties.  They were homeless.  The adult male masterminded several burglaries of Target stores and sent the girl into the stores so that she showed up on the surveillance cameras instead of him.  Because the girl had a long delinquency record the DA asked to transfer her to adult court. After a hearing, the judge kept her in juvenile court because the crimes were not violent and the girl was being manipulated by the adult male she was dating.

Non-violent teen with no prior record tried as a juvenile instead of adult

A 17-year-old employee found a gun in the store bathroom. Instead of reporting it, he kept it.  He was charged with stealing a gun and the DA moved to transfer him to adult court. Because he did not have a significant prior record and did not use the gun to threaten or hurt anyone, the judge found him suitable for juvenile court.

Recent real-world case of a juvenile tried as an adult

17-year-old with prior felonies tried as an adult instead of a juvenile

A 17-year-old boy with a long history of committing felonies robbed a store.  He was close to turning 18 and had received multiple services from the juvenile court that had not succeeded in rehabilitating him.  The judge transferred his case to adult court.

Should I get a lawyer for juvenile court?

Yes. It is the best way to protect your child from serious long-term consequences.

In Summary

Juveniles can be tried as adults but only when they meet the criteria for transfer.  A long history of delinquency and/or commission of serious felonies may trigger a transfer motion by the District Attorney. Children subject to transfer are entitled to a full hearing on the matter where the District Attorney has the burden to prove that the case should be sent to adult court.
