What the Marchman Act Petition Is and Who Uses It

A Marchman Act petition asks a Florida court to consider involuntary treatment for a person impaired by substance abuse. The petitioner describes the situation in writing, and the court weighs the evidence.

The statute lists what a petition must contain. Under Fla. Stat. § 397.68141, it includes the respondent’s name, the petitioner’s name, the relationship between them, and the respondent’s attorney’s name if known. It also includes the factual allegations that show why involuntary services may be needed.

Who may file depends on the person’s age. For an adult, § 397.68112 lists a spouse or legal guardian, any relative, a service provider, or an adult with direct personal knowledge of the impairment and prior treatment. For a minor, a parent, legal guardian, or service provider may file. Other requirements may apply, and the court decides.

Use the official form version your clerk provides. Outdated copies may cause a filing to be returned, subject to the clerk and the court.

Gather the Information Before You Start the Form

Collect the facts first, then fill in the blanks. Having everything in one place makes the form easier to complete accurately. Gather:

  • Full legal names, dates of birth, and last known addresses for the person and for yourself
  • Phone numbers and email addresses for the petitioner
  • The county where the person is physically located
  • Dated notes of specific events, including what happened, where, and who was present
  • Any prior assessments, treatment programs, or service contacts you know about, with dates
  • Names of people who saw the events and could describe them

Keep facts separate from opinions. Write “On March 3, he left the house at 2 a.m. and didn’t return until morning.” Avoid “He’s out of control.” Specific observations are easier to check than labels.

This list is not a complete statement of what any court requires. The court decides what evidence is enough.

Section-by-Section Walkthrough: Parties and Identifying Information

The first section names the respondent and the petitioner. The respondent is the person the petition is about. The petitioner is the person filing it. Fla. Stat. § 397.681 addresses jurisdiction and the right to counsel; other requirements may apply, and the court decides.

In the petitioner section, list your name, your relationship to the respondent, and your contact details. Check that your relationship fits one of the groups listed in § 397.68112.

In the respondent section, list the person’s full legal name, date of birth, and address. Accuracy matters because these details identify the person for notices and records.

Venue is also a key question. Confirm the county first.

Inconsistency between parts of the form is an error to watch for. A name may appear as a nickname in one place and a legal name in another. Pick one version and use it everywhere.

Section-by-Section Walkthrough: Factual Allegations and Substance Use History

The allegations section is the heart of the petition. It explains why you believe the person is impaired and why that matters. Under § 397.68141, the allegations must state:

  • The reason you believe the person is substance abuse impaired
  • The reason you believe the impairment has caused a loss of self-control over substance use
  • The reason you believe the person has harmed or is likely to harm self or others without a court order, or that refusal of care comes from judgment so impaired the person can’t make a rational decision about care

Write statements that are dated, specific, and first-hand. Avoid “always” or “never” unless you can support them with examples. If the person was assessed before, say when and by whom. If the person refused assessment, say so. Under § 397.68141, a refusal may need to be noted, as the statute provides; other requirements may apply, and the court decides.

If you believe there is an emergency, the petition must describe the exigent circumstances. It may also request an ex parte assessment and stabilization order. Under § 397.6818, when emergency circumstances exist, the court may rely solely on the petition and, without appointing an attorney, enter that order.

Read your allegations against the criteria in § 397.675. The court decides whether the evidence meets those criteria.

Section-by-Section Walkthrough: Signature, Verification, and Attachments

Signing is a formal step. Where a document must be verified, § 92.525 allows verification under oath or by a written declaration. 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.”

The statute makes a knowingly false declaration a felony of the third degree. Read every line and every attachment before you sign. Sign only facts you can support.

Attachments may include a qualified professional’s certificate or report. Label each attachment with the same names and dates used in the form.

For filing, go to the clerk in the county where the person is located. Other costs may apply. Confirm current procedures with the clerk. Keep a complete copy of everything you file.

Common Mistakes That Can Delay or Return a Filing

Several avoidable errors can cause a filing to be sent back or slowed down. The court decides how to handle any issue that comes up.

  • Using an outdated or unofficial version of the form
  • Leaving required fields blank without explanation
  • Mixing names, dates, or addresses across sections
  • Filing in a county other than where the person is located
  • Stating conclusions in place of observed facts
  • Signing before checking every page and attachment

A complete-looking form still goes to the court for review. Completing it carefully helps you present your facts clearly. It does not decide the result.

What Happens After Filing, Common Questions, and Next Step

After filing, the court reviews the petition and sets next steps. Timing and outcome depend on the court’s schedule and discretion, and other requirements may also apply.

At the hearing, testimony must be under oath and recorded. The respondent may refuse to testify, according to § 397.6957. The statute says the court may order involuntary treatment when it finds the conditions proved by clear and convincing evidence (§ 397.697).

Court records are confidential under § 397.6760. As the statute provides, the clerk may release these records only to the listed persons, subject to any statutory or court-ordered exceptions; other requirements may apply, and the court decides. The respondent also has a right to counsel at every stage under § 397.681.

Is there a fee to file?

The clerk may not charge a fee for filing a Marchman petition under the statute. Other costs, such as service, can apply. Robinson & Casey offers a free, confidential first consultation with no obligation to continue.
