Key Takeaways
- The Florida Marchman Act (Chapter 397, F.S.) allows family members, friends, or law enforcement to petition a court for involuntary assessment and, if warranted, involuntary treatment of someone with a severe substance use disorder who refuses help voluntarily.
- The Marchman Act is not for involuntary psychiatric commitment — it is specifically for substance use disorder. Florida's Baker Act covers mental health emergencies.
- Filing a Marchman Act petition does not require a lawyer and costs nothing. The petitioner goes to the clerk of court in the county where the person with SUD lives.
- Involuntary assessment lasts up to 5 days; if further treatment is ordered, initial involuntary treatment can last up to 60 days, with extensions possible.
- The Marchman Act works best as one tool in a comprehensive family intervention strategy — not as a standalone solution. Family support, treatment program engagement, and follow-through are essential.

What Is the Marchman Act?
The Hal S. Marchman Alcohol and Other Drug Services Act — commonly called the Marchman Act — is a Florida law (Chapter 397, Florida Statutes) that provides a legal mechanism for involuntary assessment and treatment of individuals with severe substance use disorders. It allows concerned individuals to seek court-ordered assessment and treatment for a loved one who is impaired by alcohol or drugs, poses a threat to themselves or others, and refuses to seek help voluntarily.
The Marchman Act was enacted in 1993 and represents Florida's primary legal tool for addressing the most severe cases of addiction — situations where someone's substance use has progressed to a point where they lack the capacity to make rational decisions about their own safety and treatment. Florida's Department of Children and Families (DCF) oversees the Marchman Act system.
Marchman Act vs. Baker Act: Know the Difference
Florida's Baker Act (Chapter 394, F.S.) covers involuntary psychiatric examination for mental health crises. The Marchman Act covers substance use disorder specifically. If someone is experiencing both a mental health crisis AND substance use, the Baker Act may be more appropriate initially. If the primary issue is substance use and the person refuses help, the Marchman Act is the correct tool. Many situations involve both, which is why coordination with an addiction specialist is valuable.
Who Can File a Marchman Act Petition?
Under Florida law, the following individuals may file a Marchman Act petition:
- The spouse of the person with SUD
- A relative of the person with SUD (parent, sibling, adult child)
- A guardian of the person with SUD
- Any three adults who have personal knowledge of the person's substance use and impairment
- A licensed service provider (treatment professional)
- A law enforcement officer (police can initiate protective custody under the Marchman Act)
Importantly, you do not need an attorney to file a Marchman Act petition, and there is no filing fee. The process is accessible to any family member who meets the above criteria.
Legal Criteria for the Marchman Act
To qualify for a Marchman Act petition, Florida law (§397.681) requires that the individual:
- Has lost the power of self-control with respect to substance use; AND
- Either: Has inflicted, or is likely to inflict, physical harm on themselves or others unless admitted for services; OR, due to substance use impairment, is incapable of making a rational decision about their need for assessment or treatment
This is an important legal standard. Not every person with a substance use disorder qualifies — the law is designed for situations of severe impairment and imminent risk. Documenting specific recent incidents of impairment, dangerous behavior, or stated intent to harm is essential for a strong petition.
Document Everything Before Filing
Before filing your petition, document specific, dated incidents that demonstrate the criteria: overdoses, DUIs, self-harm, dangerous behavior while intoxicated, statements about suicide or harming others, inability to care for children or self. The more specific and recent your documentation, the stronger your petition. Judges need concrete evidence of impairment and risk — not general statements about addiction history.
How to File a Marchman Act Petition: Step-by-Step
Step 1: Go to the Clerk of Court
Go to the clerk of the circuit court in the Florida county where the person with SUD resides — not where you live, if different. Ask for the Marchman Act petition form. It is available at the courthouse at no charge. Most Florida county clerks' websites also have the forms available for download.
Step 2: Complete the Petition
The petition requires you to provide:
- Your relationship to the respondent (the person with SUD)
- The respondent's name, address, and date of birth
- Specific, detailed facts describing the respondent's substance use, impairment, and recent dangerous behavior or incidents
- Why you believe the person meets the legal criteria for involuntary assessment
- Whether the person has been previously treated for substance use disorder
Be as specific as possible. Use dates, describe specific behaviors, and connect them directly to substance use impairment. The petition is sworn under oath.
Step 3: File with the Clerk and Await Ex Parte Hearing
Submit the completed petition to the clerk. A judge will review the petition — often the same day or within 24 hours — in an ex parte hearing (without the respondent present). If the judge finds probable cause that the criteria are met, they will issue an order for the respondent to be picked up by law enforcement and transported to a licensed assessment facility.
Step 4: Service and Assessment
Law enforcement will serve the court order on the respondent and transport them to an approved assessment facility. The respondent is held for assessment for up to 5 days.

What Happens After the Petition Is Filed
Involuntary Assessment (Up to 5 Days)
Once the court order is executed, the respondent is transported to a licensed assessment facility. Qualified professionals evaluate the person's substance use, physical and mental health status, and treatment needs. The assessors prepare a written report for the court recommending whether further treatment is warranted.
The Full Court Hearing
Within 10 days of the initial order, a full adversarial hearing is held. The respondent has the right to be present, to be represented by an attorney (one is appointed if they cannot afford one), and to present evidence. The court determines whether the criteria are met and whether involuntary treatment should be ordered.
Involuntary Treatment (Up to 60 Days)
If the court finds the criteria are met, it may order involuntary treatment for up to 60 days initially. Treatment must be provided at a licensed facility. Extensions of up to 90 days may be ordered if additional treatment is clinically warranted. The court monitors compliance throughout.

Limitations & Realistic Expectations
The Marchman Act is a powerful tool but has important limitations that families need to understand:
- It compels assessment, not motivation: The Marchman Act can get someone into assessment and treatment, but it cannot create internal motivation for recovery. Long-term recovery requires the person to ultimately engage with treatment voluntarily. Research on outcomes of coerced treatment is mixed — some studies show comparable outcomes to voluntary treatment, others show lower engagement.
- Enforcement can be slow: Law enforcement may take days to serve the pick-up order, depending on caseload and resources. The respondent may move or be difficult to locate.
- Treatment availability: Licensed Marchman Act assessment and treatment facilities have limited capacity. Delays in placement are common.
- It is not a cure: Even 60 days of treatment addresses only the acute phase. Long-term recovery requires ongoing outpatient treatment, peer support, and family engagement after the court-ordered period ends.
- Relationship impact: Filing a Marchman Act petition can temporarily damage or strain your relationship with your loved one. This is usually temporary — many people in long-term recovery express gratitude for the intervention — but it is a real consideration.
Alternatives to the Marchman Act
The Marchman Act should be considered in the context of other approaches, ideally with guidance from an addiction specialist:
- CRAFT (Community Reinforcement and Family Training): Evidence-based family intervention program that teaches family members how to reduce enabling behaviors, create positive incentives for treatment engagement, and effectively approach their loved one about treatment. Research shows CRAFT engages people in treatment in 64–74% of cases — significantly more effective than traditional confrontational approaches.
- Professional intervention: A trained intervention specialist can facilitate a structured family meeting designed to motivate treatment entry. ARISE and other models are less confrontational than the classic "ambush" intervention and show better engagement rates.
- Law enforcement contact: Police can initiate emergency protective custody under the Marchman Act without a court petition if they encounter someone acutely impaired and in immediate danger.
