A therapist’s office is supposed to be a vault. What a patient says stays in the room, except in a few narrow situations. One of those situations is also one of the most serious sources of legal liability for mental health professionals. It is called the duty to warn and protect, and it forces a psychiatrist, psychologist, or counselor to break confidentiality when a patient makes a credible threat against a specific person. If the professional fails to do so, and the patient carries out the threat, the victim or the victim’s family can sue the professional for money damages. This is not a theoretical risk. This is a real, and growing, area of medical malpractice law.
The duty got its name from a 1969 California case involving a university student named Prosenjit Poddar. Poddar told his psychologist that he intended to kill a woman. The psychologist did not warn the woman or her family. Poddar eventually killed her. The court ruled that the psychologist had a legal obligation to act. The judge wrote that the protective privilege of patient confidentiality ends where the public peril begins. That single idea changed how mental health professionals handle threats. Today, most states have some version of this duty, though the exact requirements vary from state to state. Some states only require a professional to warn the police or the intended victim. Other states require the professional to take reasonable steps to protect the victim, which could mean calling the police, hospitalizing the patient, or directly contacting the target.
The key point is that the duty only kicks in when there is a specific, identifiable victim and a serious threat of violence. A vague statement like “I’m so angry I could kill someone” does not trigger the duty. Neither does a general desire to harm people in a crowd. The threat must be aimed at a particular person or a narrowly defined group. The professional must also make a judgment call about whether the threat is credible. This judgment is not perfect, but courts do not punish therapists for being wrong. The law only punishes therapists for being reckless. In other words, if a reasonable therapist in the same situation would have believed the threat was real and taken action, and the therapist did nothing, that therapist can be held liable.
What does “taking action” look like in practice? It depends on the situation. The most direct approach is to call the police and give them the patient’s name and the intended victim’s name. Another option is to contact the victim directly and warn them about the threat. Many states also allow or require the therapist to consider committing the patient for involuntary psychiatric hold if the patient is a danger to others. Some therapists choose to do all three. The legal standard is not a checklist. It is a duty to use reasonable care, which means acting the way a competent mental health professional would act under the same circumstances.
The biggest mistake therapists make is assuming that confidentiality is absolute. They fear a lawsuit from the patient for breaking confidentiality more than they fear a lawsuit from a third party for failing to warn. In reality, the law gives therapists a legal shield. If a therapist discloses confidential information in good faith because they believe a patient poses a serious threat, the patient cannot successfully sue for breach of confidentiality. The disclosure is legally mandated or permitted, depending on the state. So the therapist is protected. The therapist who stays silent and does nothing, however, faces a much larger risk. If the patient harms the victim, the victim’s family will almost certainly file a malpractice lawsuit, and the therapist’s own notes will show that the threat was discussed and ignored.
There is also a second layer to this liability. Even when a therapist does not know about a specific threat, the law may still impose a duty to ask the right questions. This is the duty to assess risk. In many malpractice cases involving suicide or violence, the hospital or practice is sued not because the patient told someone about a plan and no one acted, but because no one ever asked. A standard psychiatric evaluation should include questions about thoughts of harming self or others. If the therapist fails to ask, and the patient later acts on a hidden threat, the lawyer for the victim will argue that a proper evaluation would have uncovered the risk. This makes thorough documentation essential. If the risk is assessed and a reasoned decision is made that no immediate danger exists, that decision is usually protected. But if nothing is written down, courts assume nothing was done.
For patients and their families, the takeaway is straightforward. When a loved one tells a therapist about a violent intention, that statement is not locked away forever. The therapist has a legal obligation to take it seriously and to involve outside parties when needed. For mental health professionals, the takeaway is equally simple. Do not rely on confidentiality as an excuse for inaction. Warn the target. Notify the police. Document every step. The duty to warn is not a gray area. It is a bright line, and crossing it is the only safe route.
