Helping Families Navigate Involuntary Treatment for Addiction in Florida

When Your Adult Child Has Nowhere Safe to Go

Florida’s Marchman Act is a court process that can order an adult with addiction into treatment, even when that adult does not agree. For a homeless adult child, it is one of the main legal routes to explore.

If you are searching for homeless adult addiction involuntary treatment Florida options, you have probably been here before. Maybe it was the overdose call, the hospital discharge, or the shelter that would not take your child back.

Now you don’t know where your child is sleeping tonight. Your fears are specific. You fear an overdose that ends in death. You fear jail. You fear your child will live on the street with no way out. Under all of it sits the loss of hope that anything will work.

This page explains the legal options Florida gives a family in your position and what a court looks at. It cannot promise any result. Whether a petition succeeds depends on the facts, and the court makes that decision.

What Florida’s Marchman Act Covers for an Adult

It allows voluntary admission and court-ordered assessment, stabilization and treatment, according to the Florida Department of Children and Families.

Voluntary treatment means your child agrees to go. Involuntary treatment means a judge orders it after a court process. Your child’s refusal alone doesn’t decide the case.

Under § 397.675, one test is whether your child has lost the power of self-control with respect to substance abuse. The statute also says a mere refusal of services is not, by itself, evidence of impaired judgment. Fla. Stat. § 397.675 reads: “(b) Without care or treatment, is likely to suffer from neglect or refuse to care for himself or herself; that such neglect or refusal poses a real and present threat of substantial harm to his or her well-being; and that it is not apparent that such harm may be avoided through the help of willing, able, and responsible family members or friends or the provision of other services, or there is substantial likelihood that the person has inflicted, or threatened to or attempted to inflict, or, unless admitted, is likely to inflict, physical harm on himself, herself, or another.”

The Baker Act is a different law. It addresses mental health crises. Your facts decide which law fits.

Robinson Casey limits its practice to Marchman Act petitions and guardianship matters, serving families across South Florida and statewide.

Who Can File a Petition and What It Must Show

Any relative can file a Marchman Act petition for an adult, and that includes a parent. Under § 397.68112, a spouse, legal guardian, service provider, or adult with direct personal knowledge of the impairment may also file. For homeless adult addiction involuntary treatment Florida cases, a family member is often the one who files.

The petition must name your child and you, and explain how you are related. It must also give the reasons you believe your child is impaired and has lost self-control.

The judge looks for facts, not labels. Build your record with these items:

• Dates of each overdose and each emergency room or hospital visit
• Police contacts and any arrests
• Shelter stays, and why each one ended
• Prior treatment attempts, with dates and how they ended
• Written messages in which your child talks about their own care

A petition can also rest on recent events. Under § 397.68111, protective custody or an emergency admission within the past 10 days can support a petition. So can an assessment by a qualified professional within 30 days.

Where you file matters. The petition goes to the clerk in the county where your child is located, under § 397.681. In J.P. v. J.N., the Fifth District held that filing in the wrong county is a venue problem, 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., 225 So. 3d 410 (Fla. 5th DCA 2017) For an adult who moves between shelters and the street, the county on the day of filing is a key fact. Miami-Dade directs adult petitions to the Clerk’s Office Probate Court, according to the Miami-Dade Clerk of Courts.

What Happens After a Petition Is Filed

After filing, the court must set a hearing within 10 court working days unless a continuance is granted, under § 397.68151. Unless a circuit court’s chief judge authorizes disinterested private process servers, the clerk must electronically submit the summons to a law enforcement agency for service within 6 hours after it is issued.

The court first decides whether the respondent already has an attorney or needs one appointed, and the respondent has the right to counsel at every stage under § 397.681, which the respondent may waive only if present and the court finds the waiver is knowing, intelligent, and voluntary. A respondent who cannot afford one may receive court-appointed counsel, under § 397.681. If counsel is appointed, the Office of Criminal Conflict and Civil Regional Counsel represents your child until the case ends. A Second District decision, Hillsborough County v. Albrechta, held that a respondent has a constitutional right to counsel in these proceedings.

At the hearing, the court hears all relevant evidence. Family members who know your child’s history may testify, under § 397.6957. Testimony is taken under oath and the proceedings are recorded, but the respondent may refuse to testify, and the court may order drug tests.

Treatment can be ordered only when the court finds the conditions proved by clear and convincing evidence. The court makes its own findings.

Appeals courts disagree on one procedural point. In J.C. v. State, the court failed to follow the applicable statute by essentially functioning as the absent petitioner. In doing so, the court failed to follow the applicable statute by essentially functioning as the absent petitioner. J.C. v. State, 293 So. 3d 627 (Fla. 5th DCA 2020) The Fourth District reached a different result in J.J.J. v. D.G. and certified conflict. Treat the Fifth District rule as Fifth District law, not a settled rule for the whole state.

Expect anger. Your child may feel betrayed, or may not understand why you filed. That reaction is common, and it does not by itself decide the case.

When Guardianship Comes Into the Picture

Guardianship is a separate court tool for an adult who cannot make safe decisions about personal care, housing or treatment. It is a different route from a Marchman Act petition.

Emergency temporary guardianship is for urgent danger. Under § 744.3031, a court may appoint an emergency temporary guardian only after a petition for determination of incapacity is filed. The court must specifically find that there appears to be imminent danger that your child’s physical or mental health or safety will be seriously impaired, or that property is in danger of being wasted, misappropriated, or lost, unless immediate action is taken. Notice must reach your child and their attorney at least 24 hours before the hearing, unless the petitioner demonstrates that substantial harm would occur if the 24-hour notice is given. The emergency authority expires after 90 days or when a guardian is appointed, whichever comes first. It can be extended 90 days if emergency conditions still exist.

Under § 744.331, once the court appoints the examining committee, it sets the date on which the petition will be heard. Fla. Stat. § 744.331 reads: “The adjudicatory hearing must be conducted at least 10 days, which time period may be waived, but no more than 30 days, after the filing of the last filed report of the examining committee members, unless good cause is shown.” One member must be a psychiatrist or other physician.

A plenary guardian handles broad decisions for the adult. A limited guardian holds only the powers the court grants. That difference matters when your child can make some decisions but not others.

Mental health guardianship fits when a co-occurring mental health condition is part of the facts. Your attorney reviews which route fits your facts.

How Homelessness Changes the Legal Picture

An adult with no fixed address changes how the court handles notice and location. Your records of where your child stays become part of the case.

The court hears family members who know the adult’s history, so your own account carries weight. Write down every contact, every incident and every shelter stay, with dates.

Court-ordered treatment is supervised. The court keeps jurisdiction after an order, can monitor compliance and can change the treatment, under § 397.697.

A 2025 study on involuntary commitment in addiction treatment says state laws in this area have grown in use but remain limited in application.
