When a substance use disorder places someone at serious risk and voluntary help has been refused, Florida families may hear about the Marchman Act. The law can provide a path to involuntary assessment, stabilization, or treatment services in limited circumstances. It does not guarantee recovery, and it is not simply a way to make an adult follow a family’s preferred treatment plan.
The formal name is the Hal S. Marchman Alcohol and Other Drug Services Act, found in Chapter 397 of the Florida Statutes. Because the law, court procedures, forms, and local resources can change, families should obtain advice from a qualified Florida attorney or the appropriate court rather than relying on an online article to file a case.
What the Marchman Act is designed to address
Florida law provides voluntary and involuntary pathways for substance-use assessment and services. In broad terms, involuntary admission criteria concern a person who is impaired by substance use and has lost self-control with respect to that use. Additional facts generally must show either a serious risk of physical harm or judgment so impaired that the person cannot appreciate the need for services and make a rational decision about them, together with the harm-related conditions specified by law.
A family member’s fear, frustration, or disagreement with someone’s choices is not enough by itself. The court considers statutory criteria and evidence. Recent behavior, prior assessments, treatment history, threats, neglect, medical consequences, access to substances, and the person’s current condition may all be relevant, depending on the proceeding.
Assessment and treatment are related but distinct
People often use “the Marchman Act” to describe more than one legal step. Florida law includes procedures involving protective custody, emergency admission, involuntary assessment and stabilization, and court-ordered involuntary services. Which pathway applies depends on the facts.
An assessment is intended to clarify the person’s condition and service needs. A later request for involuntary services may require findings and recommendations from a qualified professional and must satisfy additional statutory and procedural requirements. A court order authorizes services under the conditions the law permits; it does not ensure that a particular private program will accept the person or that a bed will be available.
Under the 2025 Florida Statutes, a court that finds the conditions for involuntary services by clear and convincing evidence may order services for a period not exceeding 90 days. Extensions and early release are governed by separate provisions. The court may direct services through a licensed provider, and payment or funding questions can affect which options are practically available.
Who may be able to file
For an adult respondent, the statute states that a petition for involuntary services may be filed by a spouse or legal guardian, any relative, a service provider, or an adult with direct personal knowledge of the person’s substance-use impairment and prior course of assessment and treatment. For a minor, a parent, legal guardian, or service provider may be able to file.
That description should not be treated as filing advice. The proper petitioner, required documents, venue, timing, and supporting evidence depend on the situation and the specific procedure being requested. Local clerks may provide forms and procedural information but cannot give legal advice.
What families should prepare
Before speaking with an attorney or beginning a court process, organize clear, factual information:
- Recent events that create concern, including dates and observable behavior.
- Known substances, patterns of use, overdoses, withdrawals, or medical complications.
- Statements or actions involving harm, neglect, unsafe driving, weapons, or other immediate risks.
- Previous assessments, detoxification, treatment, hospitalizations, or emergency responses.
- Current physicians, therapists, treatment providers, medications, and diagnoses, when legitimately known.
- Which family members or other adults have direct knowledge of the situation.
- Realistic licensed service options if assessment or treatment is ordered.
Separate what someone personally observed from what they heard from another person. Avoid exaggeration. Credible, specific information is more useful to legal and clinical professionals than conclusions or labels.
The Marchman Act is not a complete recovery plan
A legal order may create an opportunity for assessment or treatment, but recovery still requires appropriate clinical care, engagement, continuing support, and a plan for what follows. Families should think beyond the hearing or initial placement.
Questions may include: Which provider can address co-occurring mental health needs? What happens if medical stabilization is required? How will the family communicate with the treatment team? What continuing care will be available? What limits will the family maintain? Who will coordinate housing, transportation, work, finances, and other responsibilities?
The legal process and treatment plan should inform one another without being confused. Attorneys advise on the law. Qualified clinicians assess and recommend care. Treatment providers deliver services. A case manager or intervention professional may help the family coordinate information and practical next steps within the proper scope.
When a voluntary approach may still be possible
Considering the Marchman Act does not always mean a petition should be the first action. Depending on safety and timing, a professionally prepared intervention or another voluntary approach may give the person a meaningful opportunity to choose recovery. In other circumstances, urgent legal or emergency action may be necessary.
The decision should be based on current facts, qualified legal guidance, clinical judgment, and safety—not on a general belief that one method is always better.
