What has to be true before Tennessee will hold someone?
It depends on the danger, and the danger has to be immediate. Tennessee allows an emergency detention only when a person has a mental illness or serious emotional disturbance and poses an immediate substantial likelihood of serious harm because of it. A professional then completes a certificate of need, and the person is taken for examination. After that, a court holds a probable cause hearing before anyone can be kept longer.

A qualified professional issues a certificate of need, and a court holds a probable cause hearing. This is education, not legal advice.
The two-part test
Title 33, Chapter 6, Part 4 spells it out. First, the person has a mental illness or serious emotional disturbance. Second, the person poses an immediate substantial likelihood of serious harm under TCA 33-6-501 because of that condition. Both parts have to be true at the same time. Neither a diagnosis on its own nor a bad night on its own is enough.
What counts as serious harm
The law defines serious harm narrowly and lists what qualifies. It includes a threat or attempt at suicide or serious bodily harm, a threat or attempt at homicide or other violent behavior, placing others in reasonable fear of violent behavior and serious physical harm, or being unable to avoid severe impairment or injury from specific risks. On top of one of those, there has to be a substantial likelihood the harm will occur unless the person is placed under involuntary treatment.
Who can act
An officer authorized to make arrests, a licensed physician, a psychologist designated as a health service provider, or a professional designated by the commissioner of the Tennessee Department of Mental Health and Substance Abuse Services can take a person into custody without a civil order or warrant, for an immediate examination. A mandatory pre-screening agent is normally the examiner. If one is not available within two hours, the rules allow a physician or psychologist to step in and complete a certificate of need. A family member is not on this list, but a call can bring someone who is.
What a court does next
The certificate of need is not the end of the process. It starts one. The person is admitted for emergency diagnosis and treatment, and a probable cause hearing follows in general sessions court. Under TCA 33-6-422, if the court finds probable cause that the person needs care and treatment, it can order them held for not more than 15 days while a longer commitment under Part 5 is considered. Part 5 commitment requires its own complaint and certificates and a further hearing, so an emergency hold is temporary by design.
The substance use question
Families often ask whether the drinking or drug use alone can force a hold. Under this chapter, usually not. A 2019 report prepared for SAMHSA found that every state's civil commitment standard requires a serious mental illness, and the usual definition leaves substance use disorders out. A mental illness alongside the substance use can still meet the test. Tennessee amended Title 33 in 2024, so forms and details can shift, and TDMHSAS keeps the current ones.
If they will still talk to you
Keep the voluntary door open while you sort the legal one. Offer a ride. Sit with them and look at FindTreatment.gov. Tennessee Medicaid and state-funded care may cover parts of treatment, and the Tennessee Medicaid guide and the state-funded rehab guide explain what to verify. For the conversation, the guide for when they refuse treatment is a kind place to start.
