Concerned About a Sibling? Talk With a Marchman Act Attorney

Yes, a sibling can file a Marchman Act petition in Florida. The statute lets any relative file one for an adult whose substance use has left them unable to make safe decisions. Many families looking into a Marchman Act sibling or relative petition Florida want that answer first. This guide covers who may file, what the petition must say, what happens after filing, what it costs to start, and how it compares with guardianship.

Robinson Casey limits its practice to Marchman Act petitions and guardianship matters. The firm serves families in Miami-Dade, across South Florida, and statewide.

What the Marchman Act Is in Florida

Among its stated goals, the Legislature describes the law as providing an alternative to criminal imprisonment for substance abuse impaired adult and juvenile offenders, by encouraging their referral to service providers. Its goal is treatment in the least restrictive setting that promotes long-term recovery (§ 397.305).

Two routes matter here. Some assessment happens by agreement. Involuntary treatment starts with a petition filed with the court. This guide focuses on the petition, because that is the route families use when a loved one refuses care.

Can a Sibling or Other Relative File a Marchman Act Petition?

Yes. For an adult, the petition may be filed by the respondent’s spouse or legal guardian, any relative, a service provider, or an adult with direct personal knowledge of the impairment and prior treatment (§ 397.68112). A brother or sister is a relative.

Your role is to bring facts to the court. You describe what you have seen and why you believe your loved one is impaired. The judge decides what happens next. Testimony at the hearing is given under oath. The court shall hear and review all relevant evidence, including testimony from family members who know the person’s history (§ 397.6957).

You also carry the burden of proof. In J.C. v. State, the Fifth District reversed an order where the trial court took over the petitioner’s case after the petitioner was absent (J.C. v. State). The petitioner must bring the proof. This rule comes from Fifth District decisions. The Fourth District has disagreed with them (J.J.J. v. D.G.).

What a Petition Contains and What to Gather First

A petition must name the person and the petitioner. It must state their relationship and give the facts that support involuntary services (§ 397.68141). The factual allegations must demonstrate: (§ 397.68141).

• Why you believe your loved one is impaired by substance abuse.
• Why you believe the impairment has taken away their power of self-control.
• Why you believe they have hurt, or are likely to hurt, themselves or others. Or why their refusal of care comes from judgment too impaired to see the need.

If a qualified professional examined the person within 30 days before filing, that report can go with the petition. If the person was not assessed or refused an evaluation, the petition must say so. In an emergency, the petition must describe the emergency circumstances.

Gather these items first:

• Full legal name, address, and where the person is staying now.
• Dated incidents, such as dangerous driving, overdoses, missed work, eviction notices, or money taken.
• Past treatment, including detox stays, earlier assessments, and refused care. Include facility names where you know them.
• Records and witnesses, such as texts, call logs, police or emergency-room reports, and people who saw events firsthand.

The most common mistakes are vague statements like “he’s always drunk,” secondhand claims with no detail, and missing dates. Specific, dated facts give the court something concrete to weigh.

What Happens After the Petition Is Filed

The court reviews the petition and may enter an ex parte order for the respondent’s involuntary assessment and stabilization when the petitioner asserts that emergency circumstances exist, or when, upon review of the petition, the court determines that an emergency exists. The steps below show the typical sequence. Timing can vary with the court’s calendar.

Venue. File in the county where the person is physically located. In J.P. v. J.N., the Fifth District held that filing in the wrong county is a venue defect, not a loss of jurisdiction. 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.).

Counsel. The court decides whether the person has a lawyer or whether one should be appointed (§ 397.68151). Due process requires it (Hillsborough County v. Albrechta). For more, read Marchman Act respondent representation.

Emergency order. When an emergency is shown, the court may enter an ex parte assessment and stabilization order. An ex parte assessment and stabilization order may be entered when the petitioner asserts that emergency circumstances exist, or when upon review of the petition the court determines that an emergency exists (§ 397.6818; D.H. v. K.J.R.); the trial court erred where the petition did not establish a good faith reason to believe D.H. met the statutory criteria for involuntary assessment and stabilization. However, if the respondent does not appear at the hearing for any reason, the court may issue or reissue an ex parte assessment and stabilization order valid for 90 days if it reasonably believes the commitment criteria are met and a substance abuse emergency exists. However, if the respondent does not appear at the hearing for any reason, the court may issue or reissue an ex parte assessment and stabilization order valid for 90 days if it reasonably believes the commitment criteria are met and a substance abuse emergency exists.

Hearing. The court must set a hearing within 10 court working days unless a continuance is granted. The respondent receives a copy of the petition and notice. The court may order drug tests. The respondent may refuse to testify (§ 397.68151; § 397.6957).

Order. If the court finds the conditions proved by clear and convincing evidence, it may order treatment for up to 90 days (§ 397.697). If the court finds it necessary, a judge may direct the sheriff to take the respondent into custody and deliver him or her to the licensed service provider specified in the court order, or to the nearest appropriate licensed service provider (Lake County Clerk of Courts).

Does It Cost Money to Get Started?

The first consultation with Robinson Casey is free, confidential, and carries no obligation to continue. In that meeting, you can review your family’s situation, the timing concern, and which Marchman Act or guardianship route fits the facts.

The clerk may not charge a fee for filing a petition (§ 397.681). Service of process may carry fees. The court may prohibit those fees, or a law enforcement agency may waive them, if the petitioner is found indigent (§ 397.68112).

Treatment itself can cost money. It may also order treatment through a privately funded provider if the respondent can pay, or if someone on the respondent’s behalf voluntarily shows willingness and ability to pay (§ 397.697).

Marchman Act Petitions Compared With Guardianship

A Marchman Act petition asks a court to assess and treat an adult whose substance use is impairing their judgment. Guardianship is a separate court process. A judge gives someone legal authority to make certain decisions for an adult. The two can address different needs.

Robinson Casey handles emergency temporary guardianship, limited guardianship, plenary guardianship, and mental health guardianship. Each one fits different facts. Which path fits depends on your loved one’s condition, finances, housing, and medical decisions. Substance use may be the central issue in one case and only part of the picture in another.

Some families face related situations, such as a loved one released after an overdose who refuses treatment, or an adult child who lives in another state. Each raises its own questions.
