Marchman Act Petition for Addiction Treatment in Florida
A Marchman Act petition is a Florida court process that allows family members to petition for involuntary assessment and treatment of a loved one struggling with substance use disorder. When someone refuses voluntary help and their addiction poses risk to themselves or others, this legal tool provides a structured pathway to get them into treatment without their consent.

What Is a Marchman Act Petition for Addiction Treatment?
The Marchman Act is a Florida statute that enables families to seek court-ordered addiction assessment and treatment when voluntary intervention has failed.
Under Florida Statute § 397.675, a Marchman Act petition gives the court authority to order involuntary assessment and stabilization of a person whose substance use disorder poses a danger to themselves or others. This is not the same as general guardianship. It is narrowly tailored to addiction alone and does not transfer financial control or decision-making authority over other matters.
The petition can be filed by family members, caregivers, healthcare providers, or law enforcement in specific circumstances. The core purpose is simple: to break through denial and refusal when addiction is causing serious harm and the person won’t seek help on their own.
Who Is a Marchman Act Petition For?
A Marchman Act petition is appropriate for an adult or minor with a diagnosed or apparent substance use disorder—alcohol, opioids, stimulants, or other drugs—who has refused voluntary treatment and whose addiction is causing harm to themselves or others.
This legal tool is designed for situations where:
- Your loved one has tried treatment before but relapsed or refuses to go back
- Family intervention, confrontation, or persuasion has not worked
- The person’s addiction is causing immediate safety concerns—overdose risk, dangerous behavior, loss of housing or employment, or harm to family members
- You believe they lack the capacity or willingness to make a rational decision about seeking help
The Marchman Act is not for casual use or as a threat. It is a serious legal action taken when other approaches have been exhausted and danger is real.
What Does a Marchman Act Petition Cover?
The Marchman Act authorizes four key components: assessment, stabilization, treatment placement, and ongoing court supervision.
Involuntary Assessment
A licensed addiction professional evaluates your loved one to determine whether substance use disorder exists, its severity, and what level of care is clinically appropriate. This assessment is court-ordered and happens regardless of the person’s cooperation.
Involuntary Stabilization
If medically necessary, the person can be held for up to 5 days of medically supervised detoxification or crisis stabilization. This prevents dangerous withdrawal symptoms and allows the person to stabilize enough to engage in treatment.
Treatment Placement
Once assessed, the court can order entry into an inpatient or outpatient treatment program based on clinical need. The initial court order typically authorizes 60 days of treatment. If clinical progress warrants it, the order can be extended.
Medical Care Included
Treatment under a Marchman Act order includes psychiatric evaluation, medication-assisted treatment if clinically appropriate (such as methadone or buprenorphine for opioid use), and ongoing medical monitoring.
What It Does NOT Cover
The Marchman Act does not grant you general guardianship powers. You cannot use it to control your loved one’s finances, make medical decisions outside of addiction treatment, or override their choices in other areas of life. If broader authority is needed, a separate guardianship petition may be appropriate.
How the Marchman Act Petition Process Works
The process has seven steps, from filing through treatment placement and ongoing compliance.
Step 1: Petition Filing
Robinson & Casey prepares a detailed petition that includes factual allegations showing why involuntary assessment is necessary. The petition must demonstrate that the person has substance use disorder and that their condition poses a risk to themselves or others. We file the petition with the court in the county where your loved one resides.
Step 2: Ex Parte Hearing (If Applicable)
In emergency situations, the court may grant a temporary order without the respondent (the person subject to the petition) being present. This happens when immediate danger is shown—for example, active overdose risk or acute psychiatric crisis. The ex parte order typically lasts a few days until a full hearing can be held.
Step 3: Notice and Service
Your loved one is formally served with court documents and notice of the hearing. They have the right to know what is happening and when the hearing will occur.
Step 4: Full Hearing
Both sides present evidence before a judge. You (or Robinson & Casey on your behalf) explain why involuntary assessment is necessary. Your loved one has the right to appear, be represented by an attorney, and contest the petition. The judge hears both sides and decides whether grounds for involuntary assessment are met.
Step 5: Court Order
If the judge finds that the statutory grounds are satisfied, they issue an order for involuntary assessment. This order is legally binding and directs the respondent to submit to assessment at a designated facility.
Step 6: Assessment and Placement
A licensed facility conducts the assessment within 1 to 5 days. If the assessment confirms substance use disorder and treatment need, the facility places your loved one in an appropriate treatment program—inpatient or outpatient, depending on clinical need.
Step 7: Ongoing Compliance and Modifications
Robinson & Casey monitors the court order and coordinates with the treatment facility. If your loved one leaves treatment early or circumstances change, we can file motions to enforce the order, seek modification, or request extension if treatment is progressing well.
Timeline and What to Expect
From your first call to Robinson & Casey to your loved one entering treatment typically takes 2 to 3 weeks in routine cases. Emergency situations move faster.
Initial Consultation to Filing: 1–3 business days. If emergency circumstances exist (imminent overdose risk, acute psychiatric crisis), we can expedite this to same-day or next-business-day filing.
Ex Parte Order (If Granted): Same day or next business day.
Full Hearing: Typically scheduled within 5–10 days of filing.
Assessment Phase: 1–5 days after the court order is issued.
Treatment Placement: Within 5 days of assessment completion.
Total Timeline: 2–3 weeks from petition to treatment start in routine cases. Emergency cases can move to treatment within 5–7 days.
Treatment Duration: The initial court order covers a minimum of 60 days. The order can be extended if clinical progress warrants continued care and the court agrees.

Common Questions and Concerns
Q: Will my loved one be angry or refuse treatment after the court order?
Initial resistance is common. But treatment facilities are experienced in working with court-ordered patients. Many develop insight and engagement once in a structured program with professional support.
Q: What if the court denies the petition?
We discuss the judge’s reasons and explore whether circumstances have changed or whether a different legal approach—such as emergency temporary guardianship—may be appropriate.
Q: Can the respondent appeal the court order?
Yes. Respondents have appeal rights. We can defend the order if needed and advise on next steps.
Q: What if my loved one leaves treatment before 60 days?
The court retains authority to enforce the order. We can file motions to compel compliance or seek modification of the order.
Q: Is this the same as guardianship?
No. A Marchman Act petition is narrowly focused on addiction assessment and treatment. Plenary or limited guardianship is broader and may be considered if other decision-making authority is needed.
Q: How much does it cost?
Costs vary based on complexity and court location. We provide a clear fee estimate during the initial consultation.
Q: Can I file the petition myself without an attorney?
Technically possible, but court requirements are strict. Procedural errors can result in dismissal. Attorney representation significantly increases the likelihood of success.
