Adult Child Missing After Relapse: Florida Next Steps

Your adult child has relapsed, your calls go unanswered, and you may not know where they are. When an adult child goes missing after relapse in Florida, the next steps are to protect your child’s safety, write down what you know, and find out whether a Marchman Act petition fits your situation.

This page explains each step in plain language. This page is general information, not advice on your own case.

Where You Are Right Now

The most useful thing you can do today is turn this crisis into a short list of steps you can actually take.

You have already paid for treatment, tried interventions, and held firm on boundaries. The crisis has kept coming anyway, and every new call can feel like the last chance. Many parents in this place fear the same things: an overdose, their child in jail, their child living on the street, and losing hope that anything will work.

Those fears are real, and naming them is a fair place to start. A plan with defined steps does not promise a result, but it gives you something to do next. If your child may hurt themselves or someone else, or you need immediate crisis support, you can contact 988, the Suicide and Crisis Lifeline. The Florida Department of Health points families to 988 for this kind of support. For the broader legal picture, see our guide to involuntary commitment for addiction.

Make Sure Your Child Is Safe First

If your child may be overdosing or is in immediate danger, call 911 right away. Tell the dispatcher what you know about the substances used and what you are seeing.

If your child is missing but not in immediate danger, ask your local police department to take a missing person report. Ask officers to check your child’s last known address, and ask whether anyone has reported a recent arrest or hospital admission.

Keep a running list of every hospital, shelter, and jail you have already called. Write down the name of each person you spoke with and the time of the call. That list stops you from repeating the same calls and gives police and hospital staff a clearer picture.

Safety comes first, even when the legal steps feel more urgent. A court process moves on its own timeline, and your child’s immediate safety cannot wait for it.

Why an Adult Child Is Different From a Missing Child

A parent often cannot simply bring an adult child home for treatment, which is why many families look to the courts.

That is hard to accept when you can see the danger. Florida law, however, lets certain people ask a court to step in. Under Fla. Stat. § 397.68112, a petition for an adult may be filed by a spouse or legal guardian, any relative, a service provider, or an adult with direct personal knowledge of the substance abuse impairment and prior treatment.

The law does not remove the fear. Your child also keeps rights in the process. Under Fla. Stat. § 397.681, a respondent has the right to counsel at every stage of the judicial proceeding, though the respondent may waive that right if the respondent is present and the court finds the waiver is knowing, intelligent, and voluntary; the court can appoint a lawyer for someone who cannot afford one.

How a Marchman Act Petition Works in General Terms

A Marchman Act petition asks a Florida court to order an assessment and, if the criteria are met, involuntary treatment for a substance use disorder.

The court must find the criteria proved by clear and convincing evidence before it orders treatment. Under Fla. Stat. § 397.675, a key test is whether the person has lost the power of self-control with respect to substance abuse.

A certificate from a qualified professional who examined your child within 30 days before filing may accompany it, under Fla. Stat. § 397.68141.

In an emergency, the court may enter an ex parte order for assessment and stabilization without appointing an attorney, under Fla. Stat. § 397.6818. A provider may hold your child for no more than 72 hours of observation, unless the statute’s exceptions apply.

Whether a petition fits your situation depends on the facts, including your child’s condition and where your child can be found. For what a treatment order involves, read the Marchman Act order guide.

Common Questions About Filing

Write Down What You Know Before You Call

Write a dated timeline of what you know before you call anyone. A short, factual record helps you explain the situation clearly and quickly.

Include these details:

• The date, time, and place of your child’s last contact, and who was with your child.
• Any substances you know or suspect were used, and any recent hospital visits, arrests, or treatment episodes.
• Prior treatment attempts, with dates, and how each one ended.
• Copies of texts, call logs, and any police or hospital reports you have.

Write what you saw and what you were told, and mark which is which. This matters because the court hears evidence about your child’s history. Under Fla. Stat. § 397.6957, the court reviews testimony from family members familiar with your child’s prior history and how it relates to the current condition. A clear timeline makes that testimony easier to give accurately.

Keeping Yourself Steady While You Wait

Make a few decisions now, while you are calm, so you do not have to make them in a panic later. Waiting for news is exhausting, and that exhaustion makes clear thinking harder.

Try these steady habits:

• Keep one phone number your child can reach, so calls and messages have a clear route.
• Pick one person to speak for the family with police and hospitals, so the same facts are not repeated in conflicting ways.
• Write a short list of who handles which task, so the work does not fall on you alone.
• Decide ahead of time what you will and will not give in money or lodging.

Your mind may replay every conversation and ask what you should have done differently. Those thoughts rarely give you new information. Write them down, set them aside, and return to the next practical step on your list.
