Under Fla. Stat. \u00a7 397.675<\/a>, a person meets the criteria for involuntary admission if there is good faith reason to believe that the person is substance abuse impaired or has a substance use disorder and a co-occurring mental health disorder and, because of such impairment or disorder, has lost the power of self-control with respect to substance abuse, and also either is in need of substance abuse services and, because of substance abuse impairment, is incapable of appreciating that need and of making a rational decision about it, or is likely to suffer neglect or refuse care in a way that poses a real and present threat of substantial harm that cannot apparently be avoided through willing, able, and responsible family members or friends or other services, or has inflicted, threatened, or attempted physical harm, or, unless admitted, is likely to inflict physical harm on himself, herself, or another. A court can order assessment and treatment for a person who meets strict legal criteria. Florida calls this process the Marchman Act. This guide explains chapter 397 Florida involuntary admission substance use rules in plain English.<\/p>\n

What Chapter 397 Covers and Why It Matters for Families<\/h2>\n

Chapter 397 covers substance abuse services in Florida. Its involuntary rules matter most when drug or alcohol use puts someone at risk. Families often reach this law in a crisis. A parent may see a child using dangerously. A spouse may fear for a partner who has stopped eating, sleeping, or going to work.<\/p>\n

Many people assume that refusing treatment proves a person can’t decide for themselves. Mere refusal to receive services is not, by itself, evidence of lack of judgment about the need for services (Fla. Stat. \u00a7 397.675<\/a>). Fla. Stat. \u00a7 397.675 reads: “(b) Without care or treatment, is likely to suffer from neglect or refuse to care for himself or herself; that such neglect or refusal poses a real and present threat of substantial harm to his or her well-being; and that it is not apparent that such harm may be avoided through the help of willing, able, and responsible family members or friends or the provision of other services, or there is substantial likelihood that the person has inflicted, or threatened to or attempted to inflict, or, unless admitted, is likely to inflict, physical harm on himself, herself, or another.”<\/p>\n

The law has changed recently, so the current text controls.<\/p>\n\n

Where Part V Sits Within Florida’s Substance Abuse Statutes<\/h2>\n

Part V of Chapter 397 holds the involuntary process. The Marchman Act also allows voluntary admission, so involuntary treatment is one route among others.<\/p>\n

Section 397.68111 says a petition may be filed when a person reasonably appears to meet the criteria. It also covers a person placed in protective custody or given an emergency admission within the previous 10 days, or assessed by a qualified professional within 30 days (Fla. Stat. \u00a7 397.68111<\/a>).<\/p>\n

The statute was amended in 2024 and 2025. Older web pages may quote earlier text. The petition rules are in Fla. Stat. \u00a7 397.68141<\/a>, which notes that it was formerly s. 397.6951. The current petition section<\/a> lists that number as a former one.<\/p>\n

Who May File a Petition and What the Petition Must Say<\/h2>\n

For an adult, a petition 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 impairment and prior treatment (Fla. Stat. \u00a7 397.68112<\/a>).<\/p>\n

The petition must name the respondent and the petitioner. It must state their relationship, name the respondent’s attorney if known, and give the facts behind the request (Fla. Stat. \u00a7 397.68141<\/a>). The facts must explain why the petitioner believes the person is impaired and has lost self-control. They must also show either a risk of physical harm or judgment so impaired that the person can’t see the need for care. Vague worry is not a stated reason.<\/p>\n

A petition may include a report from a qualified professional who examined the person within 30 days before filing. If no assessment happened, or the person refused one, the petition must say so.<\/p>\n

The petition goes to the clerk in the county where the person is located. The clerk may not charge a filing fee for it (Fla. Stat. \u00a7 397.681<\/a>). Venue mistakes matter. According to the opinion in J.P. v. J.N.<\/a>, the filing of the petition in the wrong county did not divest the circuit court in Putnam County of jurisdiction.<\/p>\n

The Criteria Courts Apply Under the Statute<\/h2>\n

Under Florida law, involuntary admission requires a good faith reason to believe that the person meets the criteria set out in the statute. The first part requires substance abuse impairment, or a substance use disorder with a co-occurring mental health disorder. That condition must have caused the person to lose the power of self-control about substance use.<\/p>\n

The second part has two paths. In the first, the person needs substance abuse services, and impaired judgment keeps them from seeing that need or making a rational choice about it. In the second, the person is likely to neglect themselves or refuse care without help. That creates a real and present threat of substantial harm that does not appear avoidable through the help of willing, able, and responsible family members or friends or other services.<\/p>\n

Who must prove these facts matters. As the opinion in J.C. v. State<\/a> explains, the court failed to follow the applicable statute by essentially functioning as the absent petitioner. It reversed an order where the trial court questioned the only witness while the petitioner was absent. In C.W.R.K.<\/a>, the same court reaffirmed that rule in 2024 under the current statute.<\/p>\n

A Fourth District decision, J.J.J. v. D.G.<\/a>, reached a different result on a similar question. It created a conflict with earlier Fifth District rulings, including R.S. and C.W.R.K. The rule is not uniform across Florida.<\/p>\n\n

From Filing to Hearing: The Process in Plain Terms<\/h2>\n

After filing, the court decides whether the person has a lawyer or should get one. The hearing must be set within 10 court working days unless a continuance is granted (Fla. Stat. \u00a7 397.68151<\/a>).<\/p>\n

Emergencies move faster. The petition must describe the emergency and must include a request for an ex parte assessment and stabilization order (\u00a7 397.68141<\/a>). The court may rely on the petition alone and enter that order without appointing an attorney (Fla. Stat. \u00a7 397.6818<\/a>). A provider may not hold the person longer than 72 hours of observation unless specific conditions apply. The Second District also held that an ex parte order must rest on petition facts giving a good faith reason to believe the criteria are met (D.H. v. K.J.R.<\/a>).<\/p>\n

At the hearing, the respondent must attend unless the court finds that they knowingly, intelligently, and voluntarily waive the right to be present, or that their presence is inconsistent with their best interests or is likely to be injurious to self or others (\u00a7 397.6957<\/a>). Testimony is under oath, the proceedings are recorded, and the respondent may refuse to testify.<\/p>\n

Under \u00a7 397.681<\/a>, the respondent has the right to counsel at every stage of a judicial proceeding on a petition for involuntary treatment for substance abuse impairment. A respondent who can’t afford a private lawyer may have one appointed (\u00a7 397.681<\/a>). Under Fla. Stat. \u00a7 397.681<\/a>, a respondent has the right to counsel at every stage of a judicial proceeding relating to a petition for involuntary treatment for substance abuse impairment. Timing depends on the facts of each case.<\/p>\n

What the Statute Allows a Court to Order<\/h2>\n

If the court finds the conditions proved by clear and convincing evidence, it may order involuntary treatment services for up to 90 days (Fla. Stat. \u00a7 397.697<\/a>). The service can come from a publicly funded provider. A privately funded provider may be used if the person can pay, or if someone acting for them shows willingness and ability to pay.<\/p>\n

The court keeps authority after the order. It can monitor compliance, change the treatment, or start contempt proceedings for violating a valid order (\u00a7 397.697<\/a>).<\/p>\n

Release can come early. Before the 90-day period ends, when the conditions justifying involuntary treatment services no longer exist, the individual must be released as provided in s. 397.6971 (\u00a7 397.697<\/a>). Examples include when the individual no longer needs treatment services, or when the individual no longer meets the criteria for involuntary admission and gives informed consent to transfer to voluntary treatment status. A renewal petition must be filed before the court-ordered services period expires, and if the court grants it, the court may order involuntary treatment services for a period not to exceed an additional 90 days (Fla. Stat. \u00a7 397.6975<\/a>).<\/p>\n

Discharge planning must cover follow-up appointments, how to get prescribed medications, housing and transportation, and recovery support (Fla. Stat. \u00a7 397.6977<\/a>).<\/p>\n

The court decides each case on its own record. No one can promise how it will rule.<\/p>\n\n
