Questions about marchman act petition false information liability usually start with one worry: getting something wrong on a court form. Under Florida law, a family member who knowingly files false information can face criminal charges and civil claims. What the person knew when they signed matters most.

What legal risks or liability might a family member face if a Marchman Act petition contains false or misleading information?

A family member who knowingly files false information can face a felony perjury charge and a separate misdemeanor charge under Florida law. Civil claims may also follow. What the person knew at the time of signing matters most.

A Marchman Act petition is a sworn document. That makes its accuracy a legal issue, not just a formality. Your loved one’s safety may be what brought you here, and you want the paperwork right. Both goals fit together. This page covers the rules, the difference between a mistake and a knowing falsehood, and steps that support an accurate filing.

If you're worried that a petition you signed for a loved one has errors, you don't have to sort it out alone. Reach out to Robinson Casey. Talk it through with our team — the first consultation is free, confidential, and carries no obligation.

How does a sworn Marchman Act petition work, and why does accuracy matter to the court?

A Marchman Act petition is a written request asking a Florida court to order involuntary assessment or treatment for substance abuse impairment under Chapter 397. The petition must contain specific facts, and the court acts on them.

The petition must name the respondent and the petitioner, and state their relationship. It must also name the respondent’s attorney if known, and list the facts supporting the request (§ 397.68141). Those facts must explain why the petitioner believes the person is impaired, has lost self-control, and either has inflicted or is likely to inflict physical harm on himself, herself, or others unless the court orders involuntary services, or refuses care because impaired judgment keeps them from appreciating the need for care.

When verification is required, the filed document must include an oath or this statement: “Under penalties of perjury, I declare that I have read the foregoing, and the facts alleged are true, to the best of my knowledge and belief.” (Fla. Prob. R. 5.020(e))

Accuracy matters because, in an emergency, the court may rely solely on the petition’s contents to enter an ex parte order, without appointing an attorney first (§ 397.6818). The petition must be filed with the clerk in the county where the person is located (§ 397.681). For the general process, see our involuntary commitment for addiction guide.

What criminal perjury exposure can follow from a false statement in a sworn filing?

Knowingly making a false sworn declaration is a serious crime in Florida. Under § 92.525, a person who knowingly makes a false declaration is guilty of perjury by false written declaration, a felony of the third degree.

The Marchman Act has its own rule. Under § 397.581, a person may not knowingly and willfully furnish false information to obtain an emergency or other involuntary admission of another person. A violation is a misdemeanor of the first degree, with a fine not exceeding $5,000.

The same statute also bars causing an involuntary procedure under false pretenses. Both rules turn on knowledge and intent. They focus on what the person knew and meant to do, not only on whether a judge later sees the facts differently.

What civil claims could a loved one or other party bring over a false or misleading petition?

Civil claims are a separate path from criminal charges. They look at what was said, what the person knew, and what harm followed.

A person pulled into a proceeding based on false information could consider a civil claim against the person who supplied it. Whether such a claim has merit depends on the specific facts and the harm alleged.

Misleading statements can cause the same trouble as plain falsehoods. Leaving out a key fact, or framing an event to sound worse or better than it was, can mislead a court. A petition needs factual allegations that show the need for services, and selective framing weakens that showing.

Court records also have limits on who can see them. Under § 397.6760, these petitions and related records are confidential and exempt from public records disclosure.

How do courts and the law distinguish a knowing falsehood from an honest, good-faith mistake?

A knowing falsehood is a deliberate untruth. An honest mistake made in good faith is an error made after a real effort to get the facts right. Florida’s criminal statutes focus on knowing and willful conduct, so that line matters.

The Marchman Act also uses a good-faith standard. A person meets the criteria for involuntary admission if there is a good faith reason to believe the person is substance abuse impaired, or has a substance use disorder and a co-occurring mental health disorder, and, because of that, has lost the power of self-control with respect to substance abuse and either needs substance abuse services but is so impaired that they cannot appreciate that need and make a rational decision about it (mere refusal of services is not enough), or, without care, is likely to suffer from neglect or refuse to care for himself or herself in a way that poses a real and present threat of substantial harm that willing, able, and responsible family members or friends or other services apparently cannot prevent, or there is a substantial likelihood that the person has inflicted, or threatened or attempted to inflict, or, unless admitted, is likely to inflict, physical harm on himself, herself, or another (§ 397.675).

Good faith is about the basis you had. A family member who describes what they saw, heard, and did, as accurately as they can recall, is in a different position from one who invents or exaggerates details. The outcome of any matter depends on the facts.

How can a family member reduce the risk of an inaccurate Marchman Act petition?

Write down specific facts before you sign anything. Use dates, places, names of witnesses, and the exact words you heard.

  • Keep a dated record of each incident: what happened, when, where, and who saw it.
  • Write observations, not labels. “He could not stand on March 3” is more useful than “he’s an addict.”
  • Mark what you saw or heard yourself, and separate it from what someone else told you.
  • Re-read the draft against your notes before signing. Don’t sign a statement you can’t support.

Under § 397.6957, the petitioner carries the burden of proof by clear and convincing evidence. Testimony at the hearing is taken under oath (§ 397.6957).

Careful records help you describe the facts clearly. They can’t control how a court rules.

When should a family member talk with a lawyer about a petition they filed or are about to file?

If you already filed a petition and worry it has errors, a talk with a lawyer can help you understand your exposure. The same is true if you’re unsure what belongs in the petition.

The respondent has a right to counsel at every stage of the proceeding, though the respondent may waive that right only if present and the court finds the waiver is made knowingly, intelligently, and voluntarily (§ 397.681).

Frequently asked questions

Can a family member be charged with perjury for a Marchman Act petition?

Florida law makes knowingly false sworn declarations perjury, a third-degree felony. Honest mistakes made in good faith are treated differently.

What happens if the information in a petition turns out to be wrong?

The key question is what the person knew when they signed. Careful, documented facts help show a good-faith basis.

Are Marchman Act court records public?

Under § 397.6760, these petitions and related records are confidential and exempt from public records disclosure.
