Helping Your Family Respond When an Adult Child Is Homeless and Struggling With Addiction

Robinson Casey focuses on Marchman Act petitions and guardianship matters for families across South Florida and statewide. Talk with a lawyer about your options.

Your adult child has nowhere to sleep, and you are asking what a court can do

Can a Florida court order addiction treatment for a homeless adult child? A judge looks at whether the adult has a substance use impairment that meets the criteria in Chapter 397, the Marchman Act.

You may be reading this after a call from a hospital, a jail, or a shelter. You have paid for treatment for years. You have tried interventions and held the boundaries you were told to hold. Now your child is worse, and you want a legal way to act.

Your fears are real. You worry your child will overdose, die, end up in jail, or stay on the street with no help. This page explains what a petition must show, how the process runs, and what other legal paths exist. No one can say ahead of time how a judge will rule, because each case turns on its own facts.

If your adult child is sleeping on the street after another overdose or hospital stay, you don't have to work out the Marchman Act alone. Call Robinson Casey at (561) 849-4700 to talk through your situation. Talk it through with our team — the first consultation is free, confidential, and carries no obligation.

Is homelessness enough for a court to act?

The criteria in § 397.675 focus on substance use impairment, loss of self-control, impaired judgment, and risk of harm.

Homelessness still matters. It can show how dangerous the situation has become. A person sleeping outside while using may be unable to get food, medicine, or a safe place to recover. The petition must connect those facts to the impairment.

The statute also asks whether the harm could be avoided through willing, able, and responsible family, friends, or other services. 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.” That is why your own history of help, and what has and has not worked, belongs in the record.

What a petition has to show about substance use

A petition has to lay out specific facts for each required element.

Start with who can file. For an adult, § 397.68112 allows any relative to file. A spouse, a legal guardian, a service provider, or an adult with direct personal knowledge of the impairment and of the prior course of assessment and treatment can also file.

Next is the content. Under § 397.68141, the petition must name your child and you. It must state your relationship and give the facts behind your belief. Those facts must show substance use impairment and loss of self-control. They must also show that, because of such impairment, your child has lost the power of self-control with respect to substance abuse, and either that your child has inflicted or is likely to inflict physical harm on themselves or others unless the court orders involuntary services, or that your child’s refusal to voluntarily receive care is based on judgment so impaired by substance abuse that your child is incapable of appreciating the need for care or of making a rational decision regarding that need.

Loss of self-control means your child has lost the power to control use. Courts look for dated facts that show it, not labels.

A petition may include a report from a qualified professional who examined your child within 30 days before filing. If your child was never assessed or refused, the petition must say so.

How repeated crises fit into a petition

Repeated crises can be strong evidence. They work best when you describe each one with dates and details.

An overdose, a hospital stay, an arrest, or a disappearance each says something about your child’s condition and the risk without treatment. The court hears relevant evidence, including testimony from family members who know the adult’s history. It may also order drug tests, under § 397.6957.

Keep a written record. For each event, note:

  • the date and place
  • what happened and what you saw
  • who responded, such as EMS, a hospital, or police
  • every past treatment attempt, with dates
  • what your child said or did about treatment

Avoid relying on memory. Avoid broad words like “always” and “never.” Write down the specific events instead.

Homelessness fits here too. Time without housing, unsafe sleeping conditions, and lost access to medicine or emergency care can all be part of the picture the court reviews.

How the process works, step by step

The petition goes to the clerk of court in the county where your child is located. A hearing follows, and each step has its own timeline.

  1. Filing. Under § 397.681, the petition is filed where the person is located. The clerk may not charge a filing fee. In J.P. v. J.N., a wrong-county filing was treated as a venue problem, not a loss of jurisdiction. Choose the right county from the start anyway.
  2. Counsel. Your child has the right to a lawyer at every stage, unless your child is present in court and the judge finds that a waiver of that right is made knowingly, intelligently, and voluntarily. A court can appoint one if your child cannot pay. A Florida appeals court has held that this right is constitutional in Hillsborough County v. Albrechta.
  3. Hearing. Under § 397.68151, the court schedules a hearing within 10 court working days, unless a continuance is granted.
  4. Assessment. Under § 397.6957, your child generally must be clinically assessed before a treatment order, unless present in court and expressly waiving the assessment.
  5. Decision. Under § 397.697, the court may order treatment for up to 90 days if the conditions are proved by clear and convincing evidence.

Under § 397.6818, when the petitioner asserts that emergency circumstances exist, or the court finds an emergency exists, the court may rely solely on the petition’s contents and enter an ex parte order. A provider generally may hold a person for no more than 72 hours of observation, with listed exceptions.

The court makes the decision, not the family and not the firm. Expect waiting and testimony.

One Fifth District rule matters here. In J.C. v. State, the court failed to follow the applicable statute by essentially functioning as the absent petitioner. The Fourth District reached a different result in J.J.J. v. D.G., so this rule is not uniform across Florida.

Other legal paths when the adult child cannot make decisions

If your child cannot manage personal or financial decisions, guardianship under Chapter 744 is a separate path. It has its own standard and its own petition.

A guardianship case starts with a petition to determine incapacity. The petition must be verified and must state the specific facts behind the belief. See § 744.3201. The court then appoints an examining committee, and each member must examine the person and file his or her report with the clerk of the court within 15 days after appointment, under § 744.331.

Emergency temporary guardianship is a faster tool. The court must find imminent danger that the person’s physical or mental health or safety will be seriously impaired unless immediate action is taken. Under § 744.3031, the court must appoint counsel for the person. The authority lasts 90 days or until a guardian is appointed, whichever comes first. It may be extended for another 90 days if the emergency still exists. The petition must be verified, as described in Fla. Prob. R. 5.648.

Robinson Casey’s practice is limited to Marchman Act petitions and guardianship matters. That includes emergency temporary, plenary, limited, and mental health guardianship. Plenary and limited guardianship are different tools, and the right one depends on the facts.

Do not assume one path covers the other. Each has its own standard and its own requirements.

Common questions

Can a parent file a Marchman Act petition for an adult child?

Yes. Under § 397.68112, a petition for involuntary treatment services for an adult may be filed by the respondent’s spouse or legal guardian, any relative, a service provider, or an adult who has direct personal knowledge of the respondent’s substance abuse impairment and his or her prior course of assessment and treatment.

Does my adult child get a lawyer?

Yes. Your child has the right to counsel, which your child may waive only if present and the court finds the waiver is knowing, intelligent, and voluntary. A child who wants counsel and cannot afford private counsel has the right to court-appointed counsel, and the court must appoint counsel if it believes your child needs it, under § 397.681.
