Mental Health Diversion in California
Mental health diversion in California is a pretrial program that allows eligible defendants with qualifying mental health disorders to receive treatment instead of moving through the traditional criminal court process. If the court grants diversion, the criminal case is paused while the defendant participates in an approved treatment plan. If the defendant successfully completes diversion, the court can dismiss the charges.
The program is governed primarily by California Penal Code section 1001.36. It applies to certain misdemeanor and felony cases, but not every defendant or every charge qualifies. The court must consider whether the defendant is both eligible and suitable. This includes whether the defendant has a qualifying mental disorder, whether that disorder was a significant factor in the charged offense, whether treatment would help and whether the defendant can be safely treated in the community. California courts describe mental health diversion as a way to meet the unique treatment and support needs of people with mental health diagnoses while protecting public safety.
For someone facing criminal charges, mental health diversion can be life-changing. It may create a path toward treatment, stability and dismissal rather than conviction, jail or a permanent criminal record. If you or a loved one may qualify, speak with a California criminal defense attorney as early as possible.
Quick Answer: What Is Mental Health Diversion?
Mental health diversion is a California pretrial program that can pause a criminal case while the defendant completes mental health treatment. If the defendant performs successfully, the charges may be dismissed.
| Key Question | Short Answer |
|---|---|
| What law controls mental health diversion? | California Penal Code section 1001.36 |
| Does it apply before trial? | Yes, it is a pretrial diversion program |
| Can it apply to misdemeanors? | Yes, if the charge is eligible |
| Can it apply to felonies? | Yes, if the charge is eligible |

Why Mental Health Diversion Exists
California created mental health diversion to address a problem that courts, families and communities see every day: untreated mental illness can contribute to criminal behavior, and jail does not always solve the underlying issue.
Penal Code section 1001.35 describes the purpose of diversion as increasing diversion for people with mental disorders, allowing local flexibility in treatment-based programs and providing diversion that meets each person’s unique mental health treatment and support needs. A 2026 California Senate Public Safety Committee analysis summarizes the same purpose and explains that existing law allows courts to grant pretrial mental health diversion to eligible defendants charged with misdemeanors or felonies after considering both the defense and prosecution positions.
The goal is not to ignore criminal charges. The goal is to determine whether treatment is a better and safer response in a case where a mental health disorder contributed to the alleged conduct.
How Mental Health Diversion Works in California
Mental health diversion usually begins with a defense request. The defense presents evidence that the defendant has a qualifying mental disorder and that the disorder played a significant role in the charged offense. The defense also typically presents a treatment plan.
The prosecutor may oppose or respond to the request. The court then decides whether the defendant meets the eligibility and suitability requirements.
If diversion is granted, criminal proceedings are suspended. The defendant must follow treatment conditions, attend court reviews and comply with the program. Treatment providers may be required to submit progress reports to the court, the defense and the prosecution.
If the defendant performs satisfactorily, the court dismisses the charges at the end of the diversion period.
Who Qualifies for Mental Health Diversion?
Eligibility depends on several legal and clinical factors. The court looks at both the defendant’s mental health condition and the connection between that condition and the alleged offense.
1. The Defendant Must Have a Qualifying Mental Disorder
The defendant must suffer from a mental disorder identified in the most recent edition of the Diagnostic and Statistical Manual of Mental Disorders. The law includes conditions such as bipolar disorder, schizophrenia, schizoaffective disorder and post-traumatic stress disorder, but excludes certain disorders such as antisocial personality disorder and pedophilia.
Evidence is usually provided through a qualified mental health expert, which usually includes diagnosis or treatment for a diagnosed mental disorder within the last five years by a qualified mental health expert.
2. The Disorder Must Be a Significant Factor in the Offense
The mental disorder must have played a significant role in the alleged crime. This does not always require proving that the disorder was the only cause. The question is whether it was a motivating, causal or contributing factor.
Current law creates an important presumption. If the defendant has been diagnosed with a qualifying mental disorder, the court generally finds the disorder was a significant factor in the offense unless there is clear and convincing evidence that it was not a motivating, causal or contributing factor.
3. Treatment Must Be Likely to Help
A qualified mental health expert must give the opinion that the defendant’s symptoms would respond to treatment. This requirement matters because diversion is treatment-based. The court needs a reason to believe the proposed program can address the mental health issue connected to the case.
4. The Defendant Must Consent and Waive Speedy Trial Rights
Mental health diversion is voluntary. The defendant must agree to participate and usually must waive the right to a speedy trial while the case is paused.
This is a serious legal decision. A defendant should understand what diversion requires, what happens if they violate the program and what rights they are giving up during the diversion period.
5. The Defendant Must Agree to Comply With Treatment
Diversion is not granted simply because someone has a diagnosis. The defendant must agree to follow the treatment plan. That may include therapy, medication management, residential treatment, outpatient care, case management, substance use treatment or other court-approved services.
6. The Defendant Must Not Pose an Unreasonable Risk to Public Safety
The court must consider public safety. Under Penal Code section 1001.36, the court evaluates whether the defendant would pose an unreasonable risk of danger to public safety if treated in the community. Legislative analysis of the current law describes this suitability requirement as part of the court’s decision after eligibility is established.
7. There Must Be an Appropriate Treatment Plan
The court must be satisfied that a treatment plan is in place and meets the defendant’s specific needs.
Mental Health Diversion Eligibility Checklist
| Requirement | What the Court Looks For |
|---|---|
| Qualifying diagnosis | Evidence of a DSM-recognized mental disorder |
| Recent diagnosis or treatment | Usually diagnosis or treatment within the last five years |
| Connection to offense | Disorder was a significant factor in the charged conduct |
| Treatment response | Expert opinion that symptoms would respond to treatment |
| Consent | Defendant agrees to diversion |
| Speedy trial waiver | Defendant waives speedy trial rights during diversion |
| Treatment compliance | Defendant agrees to follow the treatment plan |
| Public safety | Court finds no unreasonable risk if treated in the community |
| Treatment plan | Program meets the defendant’s specific needs |
This is why mental health diversion motions should be carefully prepared. A diagnosis alone is rarely enough. The defense must connect the mental health evidence, the alleged conduct and the treatment plan in a way the court can evaluate.
What Charges Are Not Eligible for Mental Health Diversion?
Mental health diversion can apply to many misdemeanor and felony cases, but some charges are excluded. Current law excludes defendants charged with murder, voluntary manslaughter, offenses requiring sex offender registration with limited exceptions and offenses involving weapons of mass destruction. A California Senate Public Safety Committee analysis summarizes these exclusions under existing Penal Code section 1001.36.
Because eligibility can change based on the exact charge, enhancements, criminal history and pending legislation, defendants should not assume they qualify or are disqualified without attorney review.
What Happens If Mental Health Diversion Is Granted?
If the court grants diversion, the criminal case is paused. The defendant enters the treatment program and must follow the court’s conditions.
Diversion may include:
- Individual therapy
- Group therapy
- Medication management
- Psychiatric care
- Residential treatment
- Outpatient treatment
- Substance use treatment
- Case management
- Housing support
- Progress reviews
- Court check-ins
- Provider reports
The treatment plan can be public or private, depending on the case, available services and court approval. The exact requirements vary by county and by the defendant’s needs.
How Long Does Mental Health Diversion Last?
The maximum diversion period depends on the type of charge. Mental health diversion may last no longer than one year for a misdemeanor and two years for a felony. The court may schedule review hearings during the diversion period. The defendant’s progress, treatment compliance and public safety may be reviewed along the way.
What Happens After Successful Completion?
If the defendant performs satisfactorily in diversion, the court dismisses the criminal charges that were subject to diversion. This can be one of the most important benefits of mental health diversion. Successful completion can help a person avoid a conviction and move forward with treatment and stability.
Can Mental Health Diversion Lead to Record Sealing?
Successful diversion can result in dismissal and may also support sealing of the arrest record under the rules that apply to the case. The exact result depends on the charge, case history and court procedure.
This is an important issue to discuss with a defense attorney because record consequences can affect employment, licensing, housing and future background checks.
What Happens If Someone Fails Mental Health Diversion?
Diversion can be revoked if the defendant does not comply with treatment, commits new offenses or becomes unsuitable for continued diversion. If diversion is terminated, the criminal case can resume where it left off.
Possible reasons for termination include:
| Issue | Possible Consequence |
|---|---|
| Missing treatment appointments | Court warning, modification or termination |
| Failing to follow medication or therapy requirements | Program review or possible revocation |
| New misdemeanor involving violence concerns | Possible termination |
| New felony charge | Possible termination |
| Public safety concerns | Court may resume criminal proceedings |
| Leaving treatment without approval | Diversion may be revoked |
The court has discretion, and not every setback automatically ends diversion. But defendants should take the treatment plan seriously from the beginning.
Mental Health Diversion vs. Other Criminal Defense Outcomes
Mental health diversion is different from a plea bargain, probation or ordinary sentencing. It is designed to happen before trial and before conviction.
| Option | How It Works | Main Difference |
|---|---|---|
| Mental health diversion | Case is paused for treatment and may be dismissed after completion | Treatment-based, pretrial and may avoid conviction |
| Plea bargain | Defendant pleads guilty or no contest in exchange for agreed terms | Usually results in conviction |
| Probation | Defendant is supervised after conviction or plea | Often follows a conviction |
| Trial | Prosecutor must prove charges beyond a reasonable doubt | Risk of conviction and sentencing |
| Competency proceedings | Addresses whether defendant can understand proceedings and assist counsel | Different legal issue from diversion eligibility |
Mental health diversion can be especially powerful because it may resolve the case without a conviction if the defendant successfully completes treatment.
Why a Mental Health Evaluation Matters
A strong mental health diversion request usually depends on a credible evaluation. The evaluator should be qualified, familiar with the legal standard and able to explain the connection between the diagnosis and the alleged conduct.
A useful evaluation may address:
- Diagnosis
- Treatment history
- Symptoms
- Medication needs
- How symptoms affected behavior
- Whether the disorder contributed to the alleged offense
- Whether symptoms would respond to treatment
- Recommended level of care
- Risk factors
- Protective factors
- Treatment plan suitability
A shallow evaluation can weaken the motion. Courts need enough detail to decide whether diversion is appropriate.
Common Mistakes in Mental Health Diversion Cases
Waiting Too Long to Raise the Issue
Mental health diversion is pretrial. Waiting until the case is late in the process can make preparation harder, especially if evaluations, treatment plans and records still need to be gathered.
Assuming Any Diagnosis Is Enough
The diagnosis matters, but it is not the entire case. The defense must show that the disorder was a significant factor in the alleged offense and that treatment would likely help.
Failing to Build a Real Treatment Plan
A vague promise to get therapy may not satisfy the court. The plan should be specific, realistic and matched to the defendant’s needs.
Ignoring Public Safety Concerns
The prosecution may argue that the defendant presents a risk if treated in the community. A strong defense strategy should address public safety directly with evidence, structure and supervision.
Not Preparing the Client for Compliance
Diversion can require consistent treatment, check-ins and court appearances. The defendant needs to understand the program before agreeing to it.
Why Legal Representation Matters
Mental health diversion combines criminal defense, mental health evidence, statutory eligibility and courtroom advocacy. A defense attorney can help gather records, arrange an evaluation, prepare the motion, negotiate with the prosecution and present the treatment plan to the court.
An attorney can also help address difficult issues, including:
- Whether the charge is eligible
- Whether the diagnosis qualifies
- Whether the disorder contributed to the offense
- Whether the client is safe for community treatment
- Whether the prosecution will object
- Whether a private or public treatment plan is stronger
- What happens if diversion is denied
- What happens if diversion is violated
- What record relief may be available after completion
For many defendants and families, the legal strategy needs to move quickly. Mental health records, treatment access and court timelines can all affect the outcome.
