Marchman Act Evidence in Florida: What to Gather

A practical guide to the dated observations, records, and treatment history that help families prepare a petition, and how to organize them before your first call.

Casey III, Esq. · Published November 6, 2026

If you’re asking what evidence do you need for a Marchman Act in Florida, the short answer is facts you saw or can document. A petition must explain why you believe your loved one is substance abuse impaired and why that impairment has taken away their power of self-control. Fla. Stat. § 397.68141 sets out what a petition must contain. This guide covers the proof that supports those claims and the mistakes that weaken them.

What a Marchman Act Petition Has to Show

A petition must rest on specific facts, not general worry. It must name the respondent (the person the petition is about) and the petitioner (the person filing). It must state their relationship and name the respondent’s attorney if known. Fla. Stat. § 397.68141

The first is why the petitioner believes the person is substance abuse impaired. The second is why that impairment has taken away the person’s power of self-control.

The petition must also give one more reason. Either the person has inflicted, or is likely to inflict, physical harm on themselves or others unless the court orders involuntary services. Or their refusal of care rests on judgment so impaired by reason of substance abuse that they are incapable of appreciating their need for care and of making a rational decision regarding that need for care.

The statute adds a limit. Fla. Stat. § 397.675 Your facts need to show more than a “no” to treatment. For the full picture, read our Marchman Act overview.

Who Can File, and Why Evidence Comes First

For an adult, a spouse or legal guardian can file. So can any relative, a service provider, or an adult with direct personal knowledge of the person’s impairment and treatment history. Fla. Stat. § 397.68112

That list is broad, but one part comes with a condition: an adult filer who is not a spouse, guardian, relative, or service provider must have direct personal knowledge of the person’s impairment and prior course of assessment and treatment. Whoever files must be able to explain what they saw and why it matters. They must be ready to say it under oath at a hearing.

The petition goes to the clerk of the court in the county where the person is physically located. A petition for involuntary treatment for substance abuse impairment must be filed with the clerk of the court in the county where the person is located. However, the filing of the petition in the wrong county did not divest the circuit court in Putnam County of jurisdiction. J.P. v. J.N.

Fla. Stat. § 397.68151 For what follows, see who gets notified after a petition.

Firsthand Observations, With Dates and Specifics

The strongest evidence is what you saw, heard, or lived through yourself. Write it down with dates. A vague line like “he drinks too much” gives a court little to test.

Compare two statements. “She’s been drinking a lot lately” says very little. “On March 3, she missed her shift. When I called at noon, her speech was slurred, and she said she had taken pills with her coffee” gives a date, a place, and what happened.

Keep a dated log. Write each entry close to the event. Include the date, the place, what happened, who else was there, and what your loved one said or did. Notes made at the time are easier to stand behind than memories pieced together months later.

The hearing rules show why this matters. The court must hear all relevant evidence. That includes testimony from family members who know the person’s prior history and how it connects to the present condition. Testimony is given under oath, and the proceedings are recorded. Fla. Stat. § 397.6957

Incident Reports and Records of Contact With Services

Official records of an incident can back up what you observed. Examples include police reports, emergency room or ambulance records, overdose response reports, and arrest or citation records. Gather copies when you can, and keep the originals safe.

Never alter a document. Do not summarize it in a way that changes what it says. If you add your own notes, label them as your notes, separate from the record.

Some records are harder to get. 42 U.S.C. § 290dd-2

Federal consent rules also set detailed requirements. It must also be signed and dated. A written consent must include the required elements, and a disclosure may not be made on the basis of a consent that has expired or on its face substantially fails to conform to those requirements. 42 C.F.R. § 2.31

Treatment History and Attempts at Voluntary Help

A record of past treatment shows the court how the problem has developed. The court may weigh the person’s prior history and how it relates to the current condition. Records such as discharge summaries, program names with dates of attendance, detox stays, and counseling records may be useful to bring to a consultation.

Records showing that your loved one left treatment early can also matter. So can records of relapse after care ended. Write down what you know about each stay, including the dates and the reason it ended, if you know it.

A petition may include a report from a qualified professional who examined the person within 30 days before filing. If the person was never assessed, or refused an evaluation, the petition must say so. Fla. Stat. § 397.68141

Remember the refusal rule. A refusal of help alone does not prove lack of judgment. Whether a given record helps depends on the facts.

Statements From Witnesses and Professionals

Written statements from people with firsthand knowledge can add detail you cannot supply alone. Family members, coworkers, and neighbors may have seen changes in work, sleep, money, or safety. Each statement should describe what that person saw or heard, with dates where possible.

Never write a statement for someone and ask them to sign it. Do not pressure anyone into making one. A statement built on what someone heard from others is weak, and it can damage your case.

Witnesses may testify remotely under oath by audio-video technology. They must give the parties all relevant documents by the close of business on the day before the hearing. Fla. Stat. § 397.6957

Sworn written declarations carry legal weight. Under Florida law, the declaration reads: “Under penalties of perjury, I declare that I have read the foregoing [document] and that the facts stated in it are true.” Only sign what you know is true.

How to Organize What You Gather, and What Weakens a Petition

Organize your material in three parts. Make a timeline of events. Keep copies grouped by date. Write a short list of witnesses with their contact details. A timeline makes the pattern easy to see at a glance.

Several problems weaken a petition. Secondhand accounts without a source are one. Speculation about your loved one’s motives or feelings is another. Undated accounts and exaggeration hurt too, because a judge cannot test them.

Petition facts matter most in an emergency. The court may rely solely on the petition and enter an ex parte order without appointing a lawyer. D.H. v. K.J.R.

The petitioner carries the burden of proof. In the Fifth District, a judge who questions the only witness when the petitioner is absent acts as the absent petitioner. J.C. v. State The Fourth District has certified conflict on this point, so the rule is Fifth District law, not settled statewide. J.J.J. v. D.G.

Share private information only with people who have a real need to know. The clerk may disclose them only to listed persons, such as the petitioner, the respondent, and their attorneys. Fla. Stat. § 397.6760
