Baker Act in Missouri: 96-Hour Holds, Rights, and Next Steps

Missouri does not have a Baker Act. The Baker Act is a Florida law, and Missouri uses a different statute, Chapter 632 of the Missouri Revised Statutes, to accomplish the same thing: emergency psychiatric detention, professional evaluation, and court-ordered treatment for someone in a mental health crisis who poses a serious risk of harm.¹ The initial emergency hold in Missouri lasts up to 96 hours, and a judge can extend it after a hearing.

How Someone Gets Placed on a 96-Hour Hold

Any adult can start the process. You do not need to be a family member, doctor, or lawyer. You file an application under oath with the probate division of the circuit court in any county where the person can be found, on a form the court provides, describing why you believe the person has a mental disorder and poses a likelihood of serious harm.²

If the court finds probable cause, it directs a peace officer to take the person into custody and transport them to a mental health facility.²

Officers can also act on their own. A peace officer with reasonable cause to believe someone has a mental disorder and that serious harm is imminent can take that person into custody, transport them to a mental health facility, and complete the application at the facility.² Missouri’s Department of Mental Health also runs a 24-hour Access Crisis Intervention hotline whose staff can help families navigate the civil detention process.³

What Happens During the 96 Hours

Once the person arrives at a designated facility, the 96-hour clock starts. Mental health professionals evaluate whether the person meets the legal criteria for continued involuntary care.²

One detail catches families off guard: the 96 hours excludes Saturdays, Sundays, and legal holidays observed by either the court or the facility.⁴ A Friday-afternoon detention runs through the weekend without those days counting, so in real time the hold can last several calendar days longer than four.

If the evaluators decide the person no longer meets the criteria, the facility must release them. If continued treatment is warranted, the facility head must file a petition with the court before the 96-hour window closes.

Who Actually Qualifies

A mental health diagnosis by itself is not enough. Missouri law requires two things together: a mental disorder that distorts the person’s ability to perceive reality or control their actions, and a likelihood of serious harm resulting from that condition.⁴

“Likelihood of serious harm” covers three situations:

A substantial risk of physical self-injury, shown through recent threats, suicide attempts, or a documented pattern of self-destructive behavior.
An inability, because of the mental condition, to provide for food, shelter, clothing, safety, or medical care, creating a substantial risk of serious physical harm.
A substantial risk of seriously hurting someone else, based on recent threatening behavior, overt acts, or a history of violence tied to the mental condition.

Actual physical injury does not have to have occurred already for any of these categories to apply.⁴

Substance abuse and intoxication, standing alone, do not qualify. A person cannot be committed solely because they are addicted or intoxicated; the substance issue has to accompany a separate mental illness that independently meets the criteria.⁴ Where symptoms are real but do not cross the threshold, voluntary admission or outpatient treatment is the typical route.

What Comes After 96 Hours

If the facility head believes continued treatment is needed, a petition goes to the probate court before the emergency hold expires. It must describe the person’s specific behavior, explain the ongoing risk, confirm that less restrictive options were considered, and state that the person either refused voluntary treatment or lacks the capacity to consent.⁵

Once the petition is filed, the person can be held for up to two additional judicial days while the hearing is scheduled. The court must hold the hearing within two judicial days of the filing.⁶ The person and their attorney must receive a copy of the petition at least 24 hours before the hearing.⁵

At the hearing, the person facing commitment has the right to a lawyer (appointed if they cannot afford one), the right to present evidence and cross-examine witnesses, the right to remain silent, the right to view and copy everything in the court file, the right to choose whether the hearing is open or closed, and the right to request a jury.⁶

The petitioner must prove by clear and convincing evidence that the person, because of mental illness, presents a likelihood of serious harm, and that an appropriate mental health program has agreed to accept them. If the court agrees, it can order up to 21 days of inpatient treatment or up to 180 days of outpatient treatment, whichever is the least restrictive option.⁶

If the person is still seriously ill as the 21-day period ends, the facility can petition for more time. That second petition must be filed within 17 days of the initial hearing, and the court schedules a new hearing within four judicial days of the filing. The court can then order up to 90 additional inpatient days or up to 180 outpatient days, on the same clear and convincing evidence standard, with an individualized treatment plan attached.⁷ Each extension needs its own petition, hearing, and fresh evidence.

For someone with a persistent, severe condition and no realistic prospect of improvement, the facility can also initiate guardianship proceedings under Chapter 475, which shifts medical and financial decisions to a court-appointed guardian.⁸

Rights of the Person Being Held

Involuntary commitment does not erase a patient’s rights. Under § 630.110, patients keep their own clothes and possessions, can spend a reasonable amount of their own money, can send and receive sealed mail, can receive visitors at reasonable times, can make and receive confidential phone calls, and can access their own mental health and medical records. The facility head can restrict some of these when necessary for treatment or safety, but every restriction and its reason must be documented in the clinical record. Regardless of any restriction, every patient keeps an absolute right to private visits from an attorney, physician, or clergy, and to send sealed mail to the court, the Department of Mental Health, and their lawyer.⁹

Anyone detained under Chapter 632 can also file a writ of habeas corpus at any time, asking a court to review whether the detention is lawful.¹⁰ You don’t have to wait for the next scheduled hearing to challenge a hold you believe is unlawful.

Firearm Consequences

An involuntary commitment in Missouri triggers a federal firearms ban. Under federal law, anyone “committed to a mental institution” is prohibited from shipping, transporting, receiving, purchasing, or possessing any firearm or ammunition.¹¹ The ban has no expiration date. It stays in place until it is affirmatively removed.

Missouri courts are required to share involuntary commitment records with the Missouri State Highway Patrol for reporting to the National Instant Criminal Background Check System, so the commitment will show up on any future firearms background check.¹²

There is a path to restore firearm rights. A person committed under Chapter 632 can petition the circuit court where they live or where the commitment order was entered, submitting mental health history, criminal history, and character evidence. The court grants the petition only if the person proves by clear and convincing evidence that they are not likely to be dangerous and that restoration is not contrary to the public interest. If granted, the clerk forwards the order to the Highway Patrol, which has 21 days to update the NICS record. If denied, the person cannot file again for one year and may appeal.¹³

Minors

The rules work somewhat differently for children and teenagers. Parents or legal custodians must consent to a minor’s psychiatric treatment and have the right to consult their own physician before doing so.¹⁴ A minor voluntarily admitted who asks to leave, directly or through a parent, must generally be released immediately, but a facility can refuse to release a minor who is mentally disordered and poses a likelihood of serious physical harm and instead begin the involuntary detention process under Chapter 632, just as it would for an adult.¹⁵

Who Pays

The Department of Mental Health charges for services and works to recover costs. Third-party benefits (private insurance, Medicaid, or Medicare) are applied first. If those fall short, the patient or family is asked to contribute based on ability to pay, and a patient with no spouse or dependents who needs long-term inpatient care can have their own income and assets applied. Parents are not liable for charges for services to their adult children; for minor children, parents may be charged for certain medical expenses but not for education costs.¹⁶ Missouri law also allows recovery from a deceased patient’s estate.

When to Get a Lawyer Involved

Anyone facing involuntary commitment has a right to counsel at every stage, with a court-appointed attorney if they cannot afford one.⁶ A lawyer can test whether the evidence really meets the clear and convincing standard, argue for outpatient treatment instead of inpatient confinement, and check that the facility followed the required procedures during the emergency hold.

Family members on the other side benefit from legal guidance too. Drafting a petition that satisfies the statute, gathering the right documentation, and understanding the hearing timeline all go more smoothly with help. Where crises repeat, an attorney can walk through longer-term options like guardianship or structured outpatient programs that provide ongoing oversight without repeated emergency hospitalizations.
