Casey III, Esq. · Published November 7, 2026

A Marchman Act petition is a sworn request asking a Florida court to order assessment and, if the court finds it appropriate, treatment for a person whose substance use is causing serious harm. The strength of a petition comes from its facts. If you’re looking into evidence for Marchman Act addiction petition Florida cases rely on, you may be worried about someone you love. You may also be doing this under pressure. This page explains the kinds of facts a petition is built on and how to organize what you already know. Every case turns on its own facts.

What a Marchman Act Petition Is Built On

A Marchman Act petition is built on specific factual statements, not general worries. Florida law sets out what the petition must contain. Under Fla. Stat. § 397.68141, it must include the respondent’s name, the petitioner’s name, and the relationship between them. It must also include the factual allegations that show why services are needed for substance abuse impairment.

The law also says who may file. Under Fla. Stat. § 397.68112, an adult respondent’s spouse or legal guardian, any relative, a service provider, or an adult with direct personal knowledge of the respondent’s substance abuse impairment and his or her prior course of assessment and treatment may file.

The person the petition is about is called the respondent. If you file, you are the petitioner. The rest of this page covers what those factual allegations look like in practice.

If a loved one's substance use has your family worried about safety, you don't have to sort out the facts alone. Our team is glad to talk them through with you. Talk it through with our team — the first consultation is free, confidential, and carries no obligation.

Dated, Specific Observations of Recent Behavior

Courts look for concrete events, with dates, places, and what was seen or heard. A general statement like “he drinks too much” gives a judge little to test. A dated event gives the court something to weigh.

Useful entries often include a missed week of work or school, an emergency room visit, a dangerous episode while driving, a threat made during an argument, or money that went missing. Write each one down with the date, the place, who was present, and what happened.

Keep two lists. One holds what you saw or heard yourself. The other holds what others told you. Mark each item so the court can tell the difference. Stick to what you observed. Guesses about what your loved one meant to do can weaken your account.

Under Fla. Stat. § 397.6957, the court hears all relevant evidence, including testimony from family members familiar with the respondent’s prior history.

Evidence That Substance Use Has Caused a Loss of Self-Control

A petition must show more than substance use. It must give the reason you believe the person has lost the power of self-control with respect to substance use. Fla. Stat. § 397.675 uses the same idea as a criterion for involuntary admission.

Facts about self-control often show a pattern over time. Examples include repeated attempts to stop that failed, continued use after clear harm to health, a job, or family relationships, and withdrawal-driven behavior you personally observed. Write down what the person said they would do, and what they did next.

Pay attention to refusal. The statute says that mere refusal to receive services does not, by itself, show a lack of judgment about the need for services. Fla. Stat. § 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.”

Specific, consistent observations over time help the court see a pattern.

Facts Showing Harm, or a Likelihood of Harm, to Self or Others

The petition must also give a reason to believe the person has inflicted, or is likely to inflict, physical harm on themselves or others unless the court orders involuntary services. The other path is a refusal of care based on judgment so impaired by substance abuse that the person is incapable of appreciating the need for care and of making a rational decision about that need.

Facts that fit here include an overdose or medical emergency tied to substance use, threats or violence, and leaving young children or elders without supervision. Driving while impaired, unsafe living conditions, and an inability to meet basic needs also fit. For the criteria in Fla. Stat. § 397.675, neglect that poses a real and present threat of substantial harm is part of the test, but only where 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. Fla. Stat. § 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.”

Describe what happened, when, and what you saw. Avoid describing the person’s character. “She is selfish” says little. “On the night of the dinner party, she drove with the children in the car after drinking” tells the court what occurred.

Prior Treatment Attempts and How the Person Responded

Prior treatment matters because it shows what has already been tried and how the person responded. A petition may include a certificate or report from a qualified professional who examined the respondent within 30 days before filing. If the respondent was not assessed, or refused an evaluation, the petition must say so, under Fla. Stat. § 397.68141.

Under Fla. Stat. § 397.68111, a person may be the subject of a petition if they reasonably appear to meet the criteria for involuntary admission, or if they have been assessed by a qualified professional within 30 days. Protective custody or an emergency admission within the previous 10 days also qualifies.

Gather dates, the names of providers or facilities, and the reason treatment ended, as far as you know it. Note detox stays, counseling, or support programs. If you don’t know a detail, write that down rather than guessing.

Treatment records are protected. Under 42 U.S.C. § 290dd-2, records of a patient’s identity, diagnosis, prognosis, or treatment kept by programs or activities relating to substance use disorder education, prevention, training, treatment, rehabilitation, or research that are conducted, regulated, or directly or indirectly assisted by a federal agency are confidential and, with limited exceptions, disclosed only as the law allows. That includes disclosure with consent or by court order after a showing of good cause. 42 U.S.C. § 290dd-2 reads: “If authorized by an appropriate order of a court of competent jurisdiction granted after application showing good cause therefor, including the need to avert a substantial risk of death or serious bodily harm. In assessing good cause the court shall weigh the public interest and the need for disclosure against the injury to the patient, to the physician-patient relationship, and to the treatment services. Upon the granting of such order, the court, in determining the extent to which any disclosure of all or any part of any record is necessary, shall impose appropriate safeguards against unauthorized disclosure.”

Records, Witnesses, and Other Third-Party Documentation

Records and witnesses can back up your own account. Useful items include emergency or hospital records, police reports, school or employer notices, texts and voicemails, photographs, and statements from people who saw the same events.

Witnesses matter. At the hearing, testimony is taken under oath and the proceedings are recorded. Witnesses may testify remotely by audio-video technology. A witness who intends to testify remotely must give the parties all relevant documents by the close of business the day before the hearing. The court may also order drug tests.

Keep originals unaltered. Save the original text message or photo with its date information. Don’t edit or crop it. Keep your social media posts about the situation to a minimum while it is active.

Court records are protected too. Under Fla. Stat. § 397.6760, petitions, court orders, and related records are confidential. The clerk may release them only to listed people, including the petitioner and the petitioner’s attorney. How much weight each item carries depends on the facts of your case.

How the Affidavit Organizes the Facts

The sworn affidavit sets out your facts in a clear order, with dates, so the court can check each one. Where Florida law, a rule, or a court order requires or authorizes that a document be verified, the verification may be made under oath taken before an officer authorized to administer oaths, or by a written declaration. Under Fla. Stat. § 92.525, the 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.” It is followed by your signature. Fla. Stat. § 92.525 reads: “(2) A written declaration means the following statement: “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, except when a verification on information or belief is permitted by law, in which case the words “to the best of my knowledge and belief” may be added.”

Plain wording helps. Use short sentences, exact dates, and only the words you can personally support. Write “I saw” or “I was told” so the court knows which is which. Avoid conclusions you can’t back up, like “he will hurt someone.” State the facts and let the court draw conclusions.

The stakes are real. Under the same statute, a person who knowingly makes a false declaration is guilty of perjury by false written declaration, a felony of the third degree. That is why many families review every line with a lawyer before signing.

Location matters too. Under Fla. Stat. § 397.681, petitions are filed with the clerk in the county where the person is located.

Talk With Robinson Casey About Your Family’s Situation

If you’re weighing a Marchman Act petition, a conversation can help you sort which facts matter most. This page is the responsibility of Richard J. Casey III, Esq. Robinson Casey focuses on Marchman Act petitions and guardianship matters for families across South Florida and statewide.

Watching a loved one struggle with addiction is exhausting. You may be scared for their safety and unsure what the law allows. You don’t need every detail in order before you reach out.

The respondent has a right to counsel at every stage of the proceeding under Fla. Stat. § 397.681, but the respondent may waive that right if the respondent is present and the court finds that such waiver is made knowingly, intelligently, and voluntarily. Our team can explain how that works alongside your own notes.

The first consultation is free, confidential, and without obligation to continue.

Do I need a doctor’s assessment to file?

Not always. Under Fla. Stat. § 397.68141, a petition for involuntary services may be accompanied by a certificate or report from a qualified professional who examined the respondent within 30 days before the petition was filed. If the respondent was not assessed before the petition was filed, or refused to submit to an evaluation, the lack of assessment or refusal must be noted in the petition.

Are Marchman Act petitions confidential?

Generally yes. Petitions and related court records under this part are confidential under Florida law.

Can a family member testify?

Yes. Under Florida law, the court may hear testimony from family members familiar with the respondent’s prior history.
