A Marchman Act petition asks a Florida court to order assessment, stabilization and, if the court finds it necessary, treatment for an adult impaired by substance abuse. This guide walks through the Chapter 397 process in plain language, so you can see how it works.<\/p>\n

The Marchman Act Petition Rules in Chapter 397<\/h2>\n

The rules are not in one place. They are spread across several sections of Chapter 397.<\/p>\n

Who can file? For an adult, Fla. Stat. \u00a7 397.68112<\/a> allows a spouse or legal guardian, any relative, a service provider, or an adult with direct personal knowledge of the impairment and of the person’s prior course of assessment and treatment to file. The petition goes to the clerk of the court in the county where the person is located, under Fla. Stat. \u00a7 397.681<\/a>. The clerk may not charge a fee to file it.<\/p>\n

Other sections cover the rest of the path. Fla. Stat. \u00a7 397.68141<\/a> lists what the petition must contain. For the full overview, read our Marchman Act attorney guide<\/a>.<\/p>\n\n

What the Court Needs to Find<\/h2>\n

The petitioner must prove the case by clear and convincing evidence. That burden falls on the person who files, under Fla. Stat. \u00a7 397.6957<\/a>. The petitioner must show the person is impaired and has a history of not following treatment.<\/p>\n

The petitioner must also show the person is unlikely to take part voluntarily, or cannot decide whether help is needed. Without services, the respondent must be likely to neglect himself or herself, that neglect must pose a real and present threat of substantial harm, and there must be a substantial likelihood of serious bodily harm in the near future, as shown by recent behavior; alternatively, the refusal must rest on judgment so impaired that the respondent cannot appreciate the need for care.<\/p>\n

The statute also says mere refusal to accept services does not, by itself, show lack of judgment, under Fla. Stat. \u00a7 397.675<\/a>. Families should expect the court to ask whether willing, able family or friends could prevent the harm.<\/p>\n

What a Petition Must Say<\/h2>\n

A petition must name the respondent and the petitioner. It must explain how they are related and name the respondent’s attorney if known. Fla. Stat. \u00a7 397.68141<\/a> requires these details.<\/p>\n

The factual allegations are the heart of the petition. They must state why you believe the person is impaired. They must also state why you believe impairment has taken away self-control.<\/p>\n

The petition must also explain the harm. It must say why you believe the person has hurt or may hurt themselves or others. Or it must say why refusal rests on judgment too impaired to see the need for care.<\/p>\n

In an emergency, the petition must describe the exigent circumstances. It must also ask for an ex parte assessment and stabilization order. A report from a qualified professional who examined the person within 30 days can accompany the petition.<\/p>\n

Judges read for facts, not labels. For example, “He is an addict” says far less than “On March 3 he left the stove on, skipped meals for four days, and refused the doctor who came to the house.” Keep a simple log of dates, messages and incidents.<\/p>\n

How the Court Reviews the Petition<\/h2>\n

The court must schedule a hearing within 10 court working days, unless a continuance is granted. A copy of the petition and notice of the hearing goes to the respondent, the respondent\u2019s parent, guardian, or legal custodian if the respondent is a minor, the respondent\u2019s attorney if known, the petitioner, the respondent\u2019s spouse or guardian if applicable, and any other persons the court directs, under Fla. Stat. \u00a7 397.68151<\/a>.<\/p>\n

A respondent who wants a lawyer and cannot afford a private one has the right to court-appointed counsel, under Fla. Stat. \u00a7 397.681<\/a>.<\/p>\n

In an emergency, the court may rely only on the petition. It may enter an ex parte order without appointing an attorney, under Fla. Stat. \u00a7 397.6818<\/a>. At the hearing, testimony is under oath and recorded, and the court hears relevant family testimony.<\/p>\n

Fifth District law adds a rule on the petitioner’s role. With the petitioner absent, the court may not call and question the professional to supply the petitioner’s case, per C.W.R.K. v. Stewart Marchman Act Behavioral Healthcare<\/a>. The Fourth District reached a different result in J.J.J. v. D.G.<\/a>, so this rule is not settled statewide. The court’s findings decide the outcome.<\/p>\n

Assessment and Stabilization Versus Treatment<\/h2>\n

An emergency order for assessment and stabilization comes first. A treatment order comes only after a hearing. The court may direct a law enforcement officer to take the person into custody for evaluation, under Fla. Stat. \u00a7 397.6818<\/a>.<\/p>\n

A provider may hold the person for no more than 72 hours of observation. The statute lists exceptions, including a court-granted extension after hearing. Withdrawal, medical needs, and weekends or holidays can also extend the time.<\/p>\n

An ex parte order that is not executed by the initial hearing date is deemed void. If the person has not been assessed within 90 days, the court must dismiss the case.<\/p>\n

Treatment is different. The treatment stage has its own findings and its own time limits.<\/p>\n

Marchman Act Versus Baker Act<\/h2>\n

The Marchman Act covers substance abuse impairment. Part I of chapter 394, known as the Baker Act, covers mental illness. If at any point during the hearing the court has reason to believe that the person, because of mental illness other than or in addition to substance abuse impairment, meets the involuntary commitment provisions of part I of chapter 394, it may start involuntary examination proceedings under those provisions.<\/p>\n

The Marchman standard also reaches a person with a substance use disorder and a co-occurring mental health disorder, under Fla. Stat. \u00a7 397.675<\/a>. So one person’s situation can involve both laws.<\/p>\n

Which path fits depends on the facts. Your family’s account of recent events will shape how the court sees the case.<\/p>\n\n

How Long an Order Lasts and Whether a Petition Can Be Dropped<\/h2>\n

A treatment order can last up to 90 days. A renewal petition must be filed with the court before the court-ordered services period expires, and if the renewal is granted, the court may order up to an additional 90 days of involuntary treatment services.<\/p>\n

A person can be released early. That happens when the person no longer meets the criteria for involuntary admission and gives informed consent to transfer to voluntary treatment status, or when the person no longer needs treatment services.<\/p>\n

Whether a petition can be withdrawn depends on the stage of the case. Once a treatment order is entered, the court keeps jurisdiction for further orders and compliance monitoring, under Fla. Stat. \u00a7 397.697<\/a>. Questions about challenging an order are covered in our guide on appeals.<\/p>\n
