Involuntary Commitment in Missouri: The 96-Hour Hold

Published: October 26, 2026

Updated: October 26, 2026

When someone you love is in crisis and will not accept help, you may feel like the only thing left is to force it. Missouri has a specific process for that, and it is worth understanding before you pick up the phone. Here is how it works, and what it will not do.

Call 911 if someone is overdosing, not breathing, violent, or in immediate danger. Call or text 988 for a mental health crisis.

How does a Missouri 96-hour hold work?

It depends on who sees the danger and how fast it is moving. In an emergency, a peace officer can take someone into custody without a court order when the likelihood of serious harm is imminent, or a facility professional can start the application. In a less immediate case, any adult can file an application with the probate court, and a judge decides whether probable cause exists. Either way, the initial detention for evaluation and treatment can last up to 96 hours. Longer care needs a hearing.

Missouri handles involuntary psychiatric detention under Chapter 632 of the Revised Statutes. An emergency hold lasts up to 96 hours, excluding weekends and holidays, and a judge can then order up to 21 more inpatient days or up to 180 days of outpatient treatment. This is education, not legal advice.

What Chapter 632 covers

Missouri's involuntary process lives in Chapter 632 of the Revised Statutes, titled Comprehensive Psychiatric Services. It is built in steps, each one requiring more proof than the last. The start is short and clinical. The later stages bring in a judge, a lawyer, and a formal hearing. Most mental health care in Missouri is voluntary, and the law is written to prefer the least restrictive setting that still protects the person and the public.

The 96-hour detention

Under RSMo 632.305, an application for detention for evaluation and treatment can be made by any adult, and you do not need to be a lawyer to make it. If a judge finds probable cause, the court directs a peace officer to take the person into custody and transport them to a mental health facility for up to 96 hours. In a true emergency, a peace officer can act without a court order when there is reasonable cause to believe the person has a mental disorder and the likelihood of serious harm is imminent. A licensed physician, a registered professional nurse, or a designated mental health professional at a facility can also complete a 96-hour application.

One detail surprises families: the 96-hour count excludes Saturdays, Sundays, and legal holidays. A detention that begins on a Friday afternoon can therefore stretch across most of the following week on the calendar. The clock is firm on the other end. If the facility does not ask a court for more time before it runs out, the person must be released or admitted voluntarily.

What happens after 96 hours

If the treating team believes the person still needs care, the head of the facility can file a petition within the 96 hours asking for more. Under RSMo 632.330, the choices are up to 21 additional inpatient days, or outpatient detention and treatment for up to 180 days. A hearing must be held within two judicial days of the petition. The standard of proof is clear and convincing evidence, which is a higher bar than the probable cause needed for the first hold. Before the hearing, the person must be served with the petition and a list of witnesses at least 24 hours ahead. They have the right to a lawyer, at no cost if they cannot afford one.

The rights that travel with a hold

Being detained does not remove a person's rights. Missouri requires the facility to explain those rights orally and in writing. The person can communicate with a lawyer, can present evidence and cross examine witnesses at a hearing, and can refuse medication before an examination unless there is an imminent risk of serious physical injury. They also keep the right to be treated in the least restrictive setting that fits. Families should know they have a right to ask what is happening and to speak with the treating team, within privacy rules.

The substance use question

Chapter 632 has a track for alcohol or drug treatment and a separate track for mental illness. The treating team can request hearings for different time frames depending on which applies, and the Missouri Department of Mental Health describes both. A 2019 report prepared for SAMHSA found that the usual civil commitment standard requires a serious mental illness and leaves substance use disorders out, so the distinction matters. A lawyer can tell you which track fits your person.

If they will still talk to you

The voluntary door stays open, and it is often the faster path to care. Offer a ride. Sit with them and look at FindTreatment.gov. Missouri Medicaid and state-funded care may cover parts of treatment, and the Missouri Medicaid guide and the state-funded rehab guide explain what to verify. For the conversation, the guide for when they refuse treatment is a warm place to begin.
