Missouri 96-Hour Mental Health Hold: Timeline, Rights, and Next Steps

In Missouri, a person can be held for up to 96 hours for mental health evaluation and treatment, and the facility must either release the person, admit the person voluntarily, or file a court petition for longer detention before that time runs out. If a petition is filed, a judicial hearing follows within two judicial days. If someone you care about has just been detained, the most useful first step is to ask the facility for the exact time the 96 hours began and for a copy of the rights notice. This guide walks through the timeline, the rights, and the questions to ask. It is one of our guides in the series on involuntary psychiatric hold rules by state.

The Missouri 96-hour hold at a glance

Under Missouri law, a person who a court, physician, designated mental health professional, or peace officer believes has a mental disorder and presents a likelihood of serious harm can be detained for evaluation and treatment for a period not to exceed 96 hours, unless further detention is authorized under Chapter 632 of the Missouri Revised Statutes. That limit is about four days, and it is the number that controls everything else: the facility has to evaluate the person, decide whether to admit or release, and file any petition for longer detention inside that window. The sections that matter most are RSMo 632.305 (starting a hold), 632.310 (evaluation and release), 632.315 (court filings), 632.325 (rights notice), and 632.330 (petitions after 96 hours).

The short version of the mechanics:

Detention limit: The hold may not exceed 96 hours without further authorization under the chapter.

Filing deadline: The facility head must file the application, the rights notice, and proof the notice was given with the court within 24 hours of arrival, excluding Saturdays, Sundays, and legal holidays.

Hearing deadline: A person gets a judicial hearing within two judicial days after a petition for additional detention is filed.

Family notice: The facility must tell the guardian, and a responsible immediate family member when the person consents, within eight hours.

Who can start a Missouri hold

A hold can begin in more than one way. Any adult can sign a sworn application to the court, which must say why the applicant believes the person has a mental disorder and presents a likelihood of serious harm, and must give the facts behind that belief. A judge then looks for probable cause. A peace officer who has reasonable cause to believe the harm is imminent can take a person into custody. A licensed physician, a registered professional nurse, or a designated mental health professional at a mental health facility can also complete an application.

Once the facility accepts the application, it evaluates the person and then admits the person for treatment or releases the person. A public facility must accept applications from a court, physician, designated nurse, or mental health professional, while a private facility may. If the facility does not admit the person, it must promptly provide transportation home or to another appropriate place, unless transportation is otherwise available. When a peace officer or agency brought the person in, that officer or agency arranges the ride.

The timeline from arrival to release or petition

Knowing the clock helps families ask the right question at the right hour. In plain order, here is how the statutes line up:

Hour 0, initial detention: The 96-hour period is measured from initial detention, so ask staff to write down the date and time it started.

Within 8 hours, notice: The respondent must be told of the rights listed in the statute, orally and in writing, and a guardian and, with consent, a family member are advised.

Within 24 hours of arrival, court filing: The facility files its paperwork with the court, and the person’s attorney receives copies.

Before hour 96, the decision point: The facility head releases the person, the person agrees to voluntary admission, or a petition for further detention is filed.

Two judicial days after filing, the hearing: A court hearing decides whether further detention is authorized.

One operational detail families often miss: the 24-hour court filing clock skips Saturdays, Sundays, and legal holidays. A person who arrives on a Friday evening may not have paperwork in the court file until the following business days, even though the 96-hour hold is already running. If you cannot find a case, that gap is a common reason, so call the facility before assuming nothing was filed.

Rights the facility must explain

Missouri requires that a person accepted for evaluation be told about specific rights, both orally and in writing. The rights notice covers appointed counsel, the right to hire a private attorney at the person’s own expense, the right to a hearing, the right to present evidence and cross-examine witnesses, and the right to an interpreter. An attorney is appointed to represent the person before and after the hearing and is notified as soon as possible.

Rights notices are often handed over during the most stressful hours of a person’s stay, so it is reasonable to ask for a second copy and to ask a staff member to go through it again once the person is calmer. It is also reasonable to ask for the name and phone number of the appointed attorney at the same time.

What a petition after 96 hours can ask for

If the facility believes the person needs more time, the head of the facility files a petition within the 96 hours. The petition can ask for up to 21 days of inpatient detention or up to 180 days of outpatient detention. It has to describe the specific behavior or facts that support a finding of serious harm, say that the person needs continued care, show that less restrictive voluntary care was tried or explain why it was not, and be verified by a psychiatrist or by a physician together with a mental health professional who examined the person. If the petition seeks outpatient care, it also has to name a program that agreed to accept the person and identify family or other support.

The court must serve the petition and the petitioner’s witness list on the person and the attorney at least 24 hours before the hearing. That 24-hour window is the practical deadline for the attorney to meet with the person and for family members who have relevant observations to tell the attorney what they have seen.

Six questions to ask staff today

Instead of asking whether the person is going to be okay, ask questions that staff can answer with a time, a name, or a document. You can ask them by phone and write the answers down with the date.

Start time: What date and time did the 96-hour period begin?

Court filing: Has the application been filed with the court, and what is the case number?

Attorney: Who is the appointed attorney, and how can I reach that office?

Decision date: When will the treatment team decide whether to release, admit voluntarily, or petition?

Rights notice: Can I see the written rights notice the person received?

Discharge plan: If the person is released, where will the person go and who is arranging follow-up care?

Staff may limit what they can share about a patient without consent, so expect that some answers will come through the attorney or the person directly. Asking still creates a record that you are involved.

If someone is in immediate danger

A hold is a legal process, not an emergency service, and this site is not an emergency service. If a person is at immediate risk of harming themselves or someone else, call 911. For emotional distress or thoughts of suicide, call or text 988 to reach the 988 Suicide and Crisis Lifeline, which is available at any hour. The National Institute of Mental Health suicide prevention page explains warning signs and where to turn, and NIMH also lists ways to find help for mental illnesses.

How Missouri compares with other states

The 96-hour length is longer than the 72-hour windows many people expect. For comparison, see our guides to the Wisconsin Chapter 51 emergency detention, the Massachusetts Section 12 hold, the Pennsylvania 302 commitment timeline, and the Virginia emergency custody order and temporary detention order. Questions about firearms after a hold are covered in our guide to psychiatric holds and gun rights under federal law. The state-by-state differences are collected on the involuntary psychiatric hold rules by state hub page.

Planning for care after the hold ends

Missouri holds can end with release, voluntary treatment, or a court-ordered plan, and asking for a follow-up appointment date before discharge gives the person a concrete next step. A professional assessment can help decide whether outpatient care, residential treatment, or another level of care fits. To talk through options for a person you care about, call 866-644-7911.
