A Marchman Act petition asks a Florida court to order an assessment for an adult whose substance use is out of control. Medical and clinical evidence is what shows the court why that request is needed. This guide explains what that evidence looks like and how to organize it before you talk with a lawyer.<\/p>\n

What Is the Marchman Act, and Where Does Medical Evidence Fit?<\/h2>\n

The Marchman Act is Florida’s civil process for getting an adult with substance abuse impairment into a court-ordered assessment and stabilization. Medical evidence sits at the center of it, because the court needs facts before it orders anything. A petition is a court filing. It states why the family believes the person needs help, and the clinical records and reports back up those statements.<\/p>\n

Certain people may file. Under \u00a7 397.68112<\/a>, an adult’s 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 may file. The petition goes to the clerk in the county where the person is located, and \u00a7 397.681<\/a> says the clerk may not charge a fee to file it.<\/p>\n

Emergencies move faster. Under \u00a7 397.6818<\/a>, the court may rely on the petition alone and enter an ex parte order, meaning one issued without the other side present. A service provider may then hold the person for no more than 72 hours of observation, subject to listed exceptions. How any of this applies depends on the facts of the case. For the overview, see our involuntary commitment for addiction<\/a> guide.<\/p>\n\n

Why Does Clinical Evidence Carry So Much Weight?<\/h2>\n

Clinical evidence matters because the statute asks a medical question. The court must ask whether the person is impaired and whether that impairment has taken away their self-control. Under \u00a7 397.675<\/a>, there must be a good faith reason to believe the person is substance abuse impaired, or has a substance use disorder with a co-occurring mental health disorder.<\/p>\n

The statute then asks about harm or judgment. Fla. Stat. \u00a7 397.675<\/a> 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.” Another path is a substantial likelihood of harm to self or others. Fla. Stat. \u00a7 397.675<\/a> 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.” Family observations describe what happened. Professional findings describe what it means clinically. The court hears both. Under \u00a7 397.697<\/a>, the conditions must be proved by clear and convincing evidence before any treatment order issues.<\/p>\n

Specific evidence beats general worry. Dates, behaviors, and consequences give the court something to check. “He has been drinking a lot” is weaker than a dated account of what happened, who saw it, and what followed.<\/p>\n

What Is a Clinical Certificate, and Who Writes It?<\/h2>\n

A clinical certificate is a report from a qualified professional who examined the person within 30 days before the petition was filed. Under \u00a7 397.68141<\/a>, the petition may be accompanied by that report. If the person was never assessed or refused an assessment, the petition must say so.<\/p>\n

The report’s content matters as much as its existence. Under \u00a7 397.6957<\/a>, the report must recommend a level of substance abuse treatment, state the findings it rests on, and note any co-occurring mental health or other treatment needs. A report with no treatment recommendation leads to dismissal of the petition.<\/p>\n

A clinician’s findings describe the person’s condition. They do not replace the court’s decision. A clinician may also be called to testify. Florida’s Fifth District has held that when the petitioner is absent, the trial court may not call and question the professional to supply the petitioner’s case, in J.C. v. State<\/a> and C.W.R.K.<\/a>. The Fourth District disagreed in J.J.J. v. D.G.<\/a>, and certified conflict. The court in J.J.J. v. D.G., No. 4D2023-2185<\/a> (Fla. 4th DCA July 24, 2024) concluded: “we certify conflict with R.S., J.W., and C.W.R.K., for the reasons stated above. Affirmed; conflict certified.”<\/p>\n

Which Medical Records Show Substance Use Impairment?<\/h2>\n

The strongest proof comes from records of what happened to the person’s body and health. Emergency room and hospital visits, overdose or poisoning history, withdrawal episodes, lab and toxicology results, and prior treatment admissions all document impairment. Each one connects to a statutory element.<\/p>\n

Map each record to a question. Toxicology and prior admissions help show impairment. Repeated emergency visits after use show continued use despite harm. An overdose, injury, or unsafe act shows the kind of harm the statute describes. The court may also order drug tests under \u00a7 397.6957<\/a>, so records should show the substance history clearly.<\/p>\n

Some records may be protected. Under \u00a7 90.503<\/a>, the privilege may be claimed by the patient or the patient’s attorney on the patient’s behalf, a guardian or conservator of the patient, the personal representative of a deceased patient, or the psychotherapist, but only on behalf of the patient. That privilege does not apply to communications relevant to a proceeding to compel hospitalization, when the therapist has reasonable cause to believe the patient needs hospitalization. It also does not apply to communications made in the course of a court-ordered examination of the mental or emotional condition of the patient, or to communications relevant to the patient’s mental or emotional condition in a proceeding where the patient relies on that condition as an element of a claim or defense. Keep a dated log of incidents next to the records you already hold. Write what you saw, when, and who else was there.<\/p>\n

How Do Lack of Self-Control and Refused Treatment Show Up?<\/h2>\n

Lack of self-control usually shows up as a pattern. The person keeps using even after clear harm to health, work, housing, or family. The statute asks whether, because of impairment, the person has lost the power of self-control<\/a> with respect to substance abuse. A list of incidents, placed in order, is often more useful than a single dramatic event.<\/p>\n

Prior treatment offers can matter too. Be careful with the context.<\/p>\n

A single record rarely tells the full story. A pattern across months or years is typically more informative than one bad night. Collect records from different sources and time periods so the pattern is visible.<\/p>\n

Do Sworn Statements and Non-Medical Records Help?<\/h2>\n

Yes. A sworn statement from someone with direct knowledge can describe specific events in their own words. Testimony at a Marchman Act hearing must be taken under oath, and the proceedings must be recorded. The respondent may refuse to testify, according to \u00a7 397.6957<\/a>.<\/p>\n

A written declaration has legal weight. Under \u00a7 92.525<\/a>, a written declaration reads: “Under penalties of perjury, I declare that I have read the foregoing [document] and that the facts stated in it are true,” followed by the signature of the person making the declaration. Fla. Stat. \u00a7 92.525<\/a> reads: “(2) A written declaration means the following statement: \u201cUnder penalties of perjury, I declare that I have read the foregoing [document] and that the facts stated in it are true,\u201d followed by the signature of the person making the declaration, except when a verification on information or belief is permitted by law, in which case the words \u201cto the best of my knowledge and belief\u201d may be added.” A person who knowingly makes a false declaration under subsection (2) is guilty of the crime of perjury by false written declaration, a felony of the third degree, under Fla. Stat. \u00a7 92.525<\/a>. Sign only what you know to be true, and write facts rather than guesses.<\/p>\n

Non-medical records can support the clinical picture. Police or EMS reports, court records, employment or school notices, and written messages showing concern all help. They support the medical evidence rather than replace it. Court petitions and related records are confidential under \u00a7 397.6760<\/a>, and the clerk may release them only to listed persons or to a person or entity authorized by court order for good cause. The attorney decides how to present these materials.<\/p>\n\n

How Is Medical Evidence Different Under the Baker Act?<\/h2>\n

The Marchman Act addresses substance abuse impairment. The Baker Act addresses mental illness. That is a different question from the one the Marchman Act asks.<\/p>\n

Because the two laws ask different questions, evidence gathered for one may not fit the other. A file built around mental illness symptoms may not show impairment and loss of self-control. The Marchman Act can also apply when a substance use disorder occurs with a co-occurring mental health disorder. In that case, the clinician’s report should note both conditions, as \u00a7 397.6957<\/a> requires.<\/p>\n

What Should You Organize Before Speaking With a Lawyer?<\/h2>\n

Start with a dated timeline, one line per incident. Add copies of the medical and hospital records you already have. List the names of clinicians who saw the person, the prior treatment history, and anyone who could give a sworn statement. Note who provided each item. An organized file helps the first conversation cover more ground.<\/p>\n

Keep in mind that the person named in a petition has rights. A respondent has the right to counsel at every stage of the proceeding, though the respondent may waive that right if present and the court finds the waiver is made knowingly, intelligently, and voluntarily, under \u00a7 397.681<\/a>. The Second District has said that due process requires counsel in Marchman Act proceedings, in Hillsborough County v. Albrechta<\/a>.<\/p>\n
