Does a Marchman Act order affect gun ownership in Florida? It can, depending on the order. Questions about firearms can come up in some Marchman Act matters, so they are worth raising with an attorney during a consultation. This page explains the rules families ask about most, so you can read the order with clear questions in mind.
Why Firearms Come Up in a Marchman Act Case
If someone you love has been named in a Marchman Act petition, guns in the house can become urgent fast. The Marchman Act is Florida’s process for people with substance use impairment, and it runs under Chapter 397. A person meets the criteria for involuntary admission if there is 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 impairment or disorder has lost the power of self-control with respect to substance abuse and either (a) is in need of substance abuse services and, because of impairment, is incapable of appreciating that need and of making a rational decision about it, or (b) without care or treatment is likely to neglect themselves or refuse care, posing a real and present threat of substantial harm to their well-being, with no apparent way to avoid that harm through willing, able family or friends or other services, or there is a substantial likelihood they have inflicted, threatened, or attempted physical harm on themselves or another, or unless admitted are likely to inflict such harm. You can read the full criteria in Fla. Stat. § 397.675. The statute also asks whether the person is likely to harm themselves or others. That harm question is why firearms come up. You can read the full criteria in Fla. Stat. § 397.675.
Families ask whether guns must leave the house, whether they can stay locked up, and whether the named person can touch them. Those are fair questions. The answers come from the order’s exact words, not from a general rule of thumb. No page can tell you how one case will turn out.

Marchman Act vs. Baker Act: Why the Difference Matters for Guns
The Marchman Act and the Baker Act are often confused. The Baker Act deals with mental health, and the Marchman Act deals with substance use. Both use petitions, hearings, and emergency orders, so the paperwork can look alike. Florida’s firearm rules, however, turn on the type of finding, not on the name of the process.
Fla. Stat. § 790.064 says a person who has been adjudicated mentally defective or committed to a mental institution may not own or possess a firearm until relief is obtained. Under Fla. Stat. § 790.064, the firearm possession and ownership disability applies to a person who has been adjudicated mentally defective or committed to a mental institution, as those terms are defined in s. 790.065(2). Whether a Marchman order fits that definition is a question about the order’s exact words. For an overview of the process, read our involuntary commitment for addiction guide.
Can a Marchman Act Order Bar Gun Ownership?
The mental-health firearm statutes apply to a specific adjudication or commitment. So the first task is finding out what the court actually entered.
Start with the stage of the case. A court may enter an emergency order based on the petition’s contents, without appointing an attorney, under Marchman Act emergency orders. A temporary order can carry different terms than a final one. Next, look for any separate firearm disability a court imposed.
Then get a certified copy of the order. Read every finding and any firearm language, word by word. The wording controls what applies. The respondent also generally must be present at the hearing, unless the court finds a knowing, intelligent, and voluntary waiver or, after receiving proof of service and evaluating the circumstances, that presence is inconsistent with the respondent’s best interests or is likely to be injurious to self or others, under Fla. Stat. § 397.6957. Presence affects how the hearing record reads, so note who attended and when.
Federal and State Firearm Prohibitions to Check
Federal and Florida firearm rules run side by side, so check both. Federal firearm prohibitions are listed in 18 U.S.C. § 922. Federal law also lets a prohibited person apply to the Attorney General for relief; that process is in 18 U.S.C. § 925, and § 922 separately excludes a person who has been granted relief from disabilities under subsection (c) of section 925. Under 18 U.S.C. § 925, the Attorney General may grant relief if the applicant is not likely to act dangerously and relief is not contrary to the public interest. A denial can be reviewed in a United States district court.
Section 790.064 covers possession and ownership, and section 790.065 governs licensed dealer sales and background checks; a person denied a purchase under that procedure may request a criminal history records review and correction in accordance with the rules promulgated by the Department of Law Enforcement. Keep the categories separate when you read the order. A substance-use finding and a mental-health adjudication raise different questions. Each one needs its own check against the actual language. Don’t assume a category applies because the case feels serious.
Firearms in the Home During a Marchman Act Case
Families often ask whether they must remove firearms from the home. The order’s terms answer that question first. A court may address firearm possession in the order or in related filings. Following those terms closely protects everyone in the household and keeps the case moving.
Until you’ve read the order’s language, don’t move, sell, or transfer any gun. A rushed move can create new problems for the household. Ask the questions in writing so you have a record of what was asked and answered.
Hearings also give family members a voice. Under Fla. Stat. § 397.6957, the court hears all relevant evidence. That includes testimony from family members familiar with the respondent’s prior history. The court may also order drug tests. Stick to facts you saw or know directly, and say how you know them. Clear, specific facts help the court understand the household’s situation.
Petitions to Remove a Firearm Disability in Florida
Florida lets a person ask the court for relief from a firearm disability through a petition. The petition goes to the court that made the adjudication or commitment, or to the court that ordered the record be submitted to the Department of Law Enforcement pursuant to s. 790.065(2), under Fla. Stat. § 790.064. Section 790.065(2) provides that, upon a request for a criminal history record check, the Department of Law Enforcement reviews any records available, during the licensee’s call or by return call, to determine whether the potential buyer or transferee is prohibited from buying a firearm, including because the person has been adjudicated mentally defective or committed to a mental institution.
The person seeking relief must follow the procedures set forth in s. 790.065(2) for obtaining relief from the firearm purchase disability, and s. 790.065(2) provides that the state attorney may object and present evidence, the petitioner may present evidence and subpoena witnesses, and the petitioner may confront and cross-examine witnesses. A court reporter or approved electronic means records the hearing. The court must make written findings and issue a final order.
If the court denies relief, the petitioner must wait one year before filing again. Review of a denial goes to the district court of appeal, and that review is de novo, meaning it starts fresh. Relief on one adjudication does not clear firearm rights tied to a different reason. Each petition turns on its own record, and no outcome can be promised.

How Long a Marchman Act Order Can Last and Why It Matters for Firearms
A court may order involuntary treatment services for a period not to exceed 90 days. That limit comes from Fla. Stat. § 397.697. Before the court-ordered services period expires, a petition for renewal of the involuntary treatment services order must be filed with the court when a service provider believes the person still meets the criteria for involuntary services (Fla. Stat. § 397.6975). The court may then extend services for an additional period not to exceed 90 days.
When the conditions justifying services no longer exist, the individual must be released as provided in s. 397.6971, which can come before the 90-day period ends. Emergency observation has its own clock. A service provider may not hold a respondent for more than 72 hours of observation, unless a listed exception applies, as set out in Fla. Stat. § 397.6818.
Timelines matter for firearms because the stage of the case shows which terms may be in place. Release from treatment is a separate event from firearm relief. The early-release statute addresses release from services. It says nothing about firearms. So confirm the case status in writing, and read each order’s terms closely.
Practical Steps for Families Right Now
Start by gathering the paperwork. Collect the petition, every order, every notice, and every hearing date. Put them in one folder, in date order. This makes it easier to check firearm questions against the actual record.
Next, list each firearm in the home. Write down who owns it and where it is stored. Keep this list factual and private. Don’t move or transfer anything until the order’s terms are clear.
Keep a written log of dates, phone calls, visits, and any contact with law enforcement. Note what was said and who said it. A clear timeline helps anyone reviewing the case move faster.
Know the rights that apply. Under Fla. Stat. § 397.681, a respondent has the right to counsel at every stage, although the respondent may waive that right if present and the court finds the waiver is made knowingly, intelligently, and voluntarily. A respondent who cannot afford private counsel may receive court-appointed counsel. The same section says the clerk may not charge a fee to file the petition. Filing in the wrong county is a venue defect, not a loss of jurisdiction, under J.P. v. J.N..
