Does Florida Have a 5150 Hold? Understanding Florida’s Involuntary Commitment Laws
Florida does not have a 5150 hold. The 5150 designation is California’s legal code for involuntary psychiatric holds. In Florida, involuntary commitment operates under two separate statutes: the Baker Act for mental health crises and the Marchman Act for substance use disorder. If you’re familiar with California’s system and now in Florida, understanding which tool applies to your situation is critical—they have different criteria, timelines, and legal processes.

Florida does not have a 5150 hold—here’s what it has instead
The 5150 is California’s Penal Code section for involuntary psychiatric holds. Florida’s involuntary commitment framework is built on two distinct statutes, each addressing a different crisis. The Baker Act handles mental illness. The Marchman Act handles addiction and substance abuse. Both allow emergency placement, but the pathways, timelines, and decision-makers are different. Knowing which one applies can mean the difference between a swift intervention and a delayed response in a crisis.
What is the Baker Act in Florida?
The Baker Act is Florida’s primary law for emergency involuntary mental health commitment. Codified in Florida Statute § 394.463, it authorizes law enforcement, physicians, mental health professionals, and certain other authorized individuals to initiate an emergency involuntary hold when someone is deemed a danger to themselves or others, or unable to care for themselves due to mental illness.
The initial Baker Act hold lasts up to 72 hours. During that time, the person is taken to a receiving facility for psychiatric evaluation. If, after 72 hours, the facility believes the person still meets the criteria for involuntary placement, it may file a petition to extend the hold. An extension can last up to 5 additional days. Any further extension requires court involvement and stricter legal standards. The person has the right to a hearing and legal representation at any extension stage.
The Baker Act was enacted in 1971 and is named after former Florida Representative Maxine Baker. It remains the foundation of Florida’s mental health crisis response system.
What is the Marchman Act in Florida?
The Marchman Act is Florida’s law for involuntary assessment and treatment of substance use disorder. Codified in Florida Statute § 397.675, it allows family members, healthcare providers, and law enforcement to petition the court for involuntary placement when someone is unwilling or unable to seek treatment for addiction. Addiction is recognized as a disease requiring evidence-based treatment, and the Marchman Act provides a legal pathway for intervention when voluntary treatment is refused.
Unlike the Baker Act, the Marchman Act requires a court petition. A judge reviews the petition and supporting evidence before ordering an assessment or treatment. The initial assessment period is up to 5 days. If the court finds that criteria are met, it can order up to 60 days of involuntary treatment. The Marchman Act was enacted in 1993 and addresses substance abuse as a distinct legal matter from mental illness alone.
Are 5150 and Baker Act the same?
No. The 5150 is California’s statute; the Baker Act is Florida’s equivalent for mental health crises. Both allow emergency involuntary psychiatric holds, but they operate under different timelines, criteria, and procedural requirements. California’s 5150 hold is typically 72 hours, similar to Florida’s initial Baker Act hold. However, the extension processes, rights protections, and documentation standards differ. If you are moving from California to Florida or are familiar with California’s system, the Baker Act is the closest parallel—but the details matter in a crisis.
How do I get someone involuntarily committed in Florida?
For a mental health crisis: Contact law enforcement or a licensed mental health professional. They can initiate a Baker Act hold if the person meets the criteria. The person is taken to a receiving facility for evaluation. No court petition is required to start the process.
For substance use disorder: You or a healthcare provider must file a Marchman Act petition with the court in the county where the person resides. The petition must include specific facts showing that the person meets the legal criteria for involuntary assessment or treatment. A judge reviews the petition and may order an assessment or treatment.
Both processes begin with clear documentation of the person’s condition and the specific legal criteria that apply—whether danger to self or others, inability to care for oneself, or need for treatment.

What happens after a 72-hour hold in Florida?
After the initial 72-hour Baker Act hold, the receiving facility must make a decision. It can either release the person or file a petition to extend involuntary placement. If the facility files for extension, the person has the right to a hearing and legal representation. The person can contest the extension, and a judge will review the evidence.
If the hold is extended, it can last up to 5 additional days. After that, any further extension requires stricter legal standards and court approval. During this time, the person may also be transitioned to voluntary treatment, outpatient services, or discharge. The facility must document its findings and the person’s rights at each stage.
What is the new mental health law in Florida?
Florida continues to operate under the Baker Act (since 1971) and Marchman Act (since 1993) as its primary involuntary commitment statutes. Recent legislative updates have refined procedures, rights protections, and facility standards, but the core framework remains unchanged. Recent changes have focused on improving access to treatment, protecting due process rights, clarifying criteria for involuntary placement, and ensuring that people in crisis receive appropriate care.

Key Difference
Florida does not have a 5150 hold. Instead, Florida uses the Baker Act for mental illness and the Marchman Act for substance abuse. Each serves a different purpose and follows different procedures.
Baker Act vs. Marchman Act: When Each Applies
Baker Act (Mental Illness)
Applies to individuals experiencing a mental health crisis. Allows for involuntary assessment and short-term hold without a court petition. Initial hold is up to 72 hours for evaluation.
Marchman Act (Substance Abuse)
Applies to individuals struggling with addiction. Requires a court petition filed by a family member, healthcare provider, or law enforcement. Initial assessment period is up to 5 days; court-ordered treatment can extend to 60 days.
Cannot Use Baker Act for Addiction
The Baker Act covers mental illness only. Substance abuse alone does not qualify. If someone needs involuntary commitment for addiction, the Marchman Act is the correct legal path.
Court Petition Required for Marchman
Unlike the Baker Act, the Marchman Act requires filing a formal petition with the court. An attorney guides the process, presents evidence, and advocates for the treatment order.
