Florida’s duty to warn is a legal obligation that requires certain people to alert others about foreseeable dangers they know about. It applies most often to three groups: mental health professionals who learn a patient plans violence, property owners who know about hidden hazards on their land, and employers who use hazardous chemicals in the workplace. Each situation has its own trigger, its own statute, and its own consequences when the warning never comes. Florida’s 2023 tort reform also changed what an injured person can recover and how quickly they must file, so a failure-to-warn claim today looks different from one filed a few years ago.
When Therapists Must Warn
Florida Statute 491.0147 governs when a licensed therapist, counselor, or other mental health professional may break patient confidentiality. The default is that everything a patient says stays private. The statute carves out a narrow exception when a patient makes a specific threat to cause serious bodily injury or death to someone the therapist can identify or readily locate.
Before disclosing anything, the professional has to make a clinical judgment that the patient has both the apparent intent and the ability to carry out the threat right away. General hostility or venting does not qualify. The threat has to be aimed at a specific person, and the therapist has to conclude the patient could act on it imminently.
When those conditions are met, the statute creates two separate tracks. The therapist may contact the potential victim directly. The therapist must report the threat to a law enforcement agency, which is then required to take steps to prevent the harm, including notifying the intended victim or seeking a risk protection order.1Florida Senate. Florida Code Title XXXII Chapter 491 Section 491-0147 – Confidentiality and Privileged Communications
That distinction matters. A therapist who contacts the potential victim is exercising a discretionary power. A therapist who fails to notify law enforcement is violating a legal obligation. Most professionals do both when a threat is credible, but the law only penalizes the failure to contact law enforcement.
A therapist who breaks confidentiality under either track is shielded from legal consequences. Florida law says that disclosing a patient’s threat under Section 491.0147 cannot be the basis for any lawsuit, criminal prosecution, or civil liability against the therapist.1Florida Senate. Florida Code Title XXXII Chapter 491 Section 491-0147 – Confidentiality and Privileged Communications The immunity only applies when the disclosure follows the statutory requirements. Sharing patient information outside those narrow circumstances gets no statutory protection.
What Property Owners Have to Warn About
Property owners have their own duty to warn under premises liability law. What the owner owes depends on why the visitor is there. Florida sorts visitors into three categories, and each one triggers a different level of responsibility.
Invitees
An invitee is someone on the property for a purpose connected to the owner’s business: shoppers, diners, patients at a medical office. Owners owe invitees the highest duty. They must keep the property reasonably safe and warn about any dangerous conditions the owner knows about or should have discovered through a reasonable inspection. The qualifier is that the hazard is not open and obvious. A pothole hidden behind a display shelf needs a warning. A visible curb does not.
Licensees
A licensee is a social guest or someone on the property with permission but not for the owner’s commercial benefit. A friend visiting your home fits here. The owner has to warn licensees about known hidden dangers but has no obligation to inspect the property for hazards that haven’t been discovered yet. The practical difference is that an invitee can argue the owner should have found the hazard; a licensee generally cannot.
Trespassers
Florida separates discovered and undiscovered trespassers, and the difference is significant. An undiscovered trespasser is someone whose presence the owner had no reason to know about. The owner’s only obligation is to avoid injuring that person through intentional misconduct. There is no duty to warn. A discovered trespasser is one the owner detected, or was alerted to, within 24 hours before an accident. For a discovered trespasser, the owner must avoid gross negligence and must warn of dangerous conditions the owner knows about but that are not readily observable.2The Florida Legislature. Florida Statutes 768.075 – Immunity From Liability for Injury to Trespassers on Real Property
Child Trespassers and Attractive Nuisance
Florida carves out an exception for child trespassers through the attractive nuisance doctrine. When a property has an artificial condition likely to attract children who are too young to understand the risk, the owner may be liable for injuries even though the child was technically trespassing. Florida Statute 768.075 explicitly preserves this common-law doctrine.2The Florida Legislature. Florida Statutes 768.075 – Immunity From Liability for Injury to Trespassers on Real Property
Swimming pools are the most common example. Florida’s Residential Swimming Pool Safety Act requires barriers at least four feet high, self-closing and self-latching gates, and exit alarms on doors that open to the pool area. Abandoned appliances like refrigerators and freezers are also specifically listed as attractive nuisances under Florida Statute 823.08. A property owner who knows children are likely to wander onto the property has to take reasonable steps to eliminate the danger or protect those children, regardless of whether they were invited.
The Slip-and-Fall Rule for Businesses
The most litigated duty-to-warn scenario in Florida involves customers slipping on spilled liquids, fallen produce, or other temporary hazards in stores and restaurants. Florida Statute 768.0755 addresses these “transitory foreign substance” claims and puts the burden squarely on the injured person.
To recover, the customer has to prove the business had actual or constructive knowledge of the dangerous condition and should have taken action to fix it. Constructive knowledge can be shown by evidence that the hazard existed long enough that any reasonable business should have noticed, or that the same type of hazard occurred so regularly that it was foreseeable.3The Florida Legislature. Florida Statutes 768.0755 – Premises Liability for Transitory Foreign Substances in a Business Establishment Simply showing that you fell on a wet floor is not enough. You need evidence the business knew or should have known and did nothing about it.
What a Sufficient Warning Looks Like
Meeting the duty to warn is straightforward in concept. The goal is to make a hidden danger obvious before someone gets hurt. Posting a clear sign near the hazard is the most common method. Physical barriers like cones, ropes, or caution tape work when a sign alone might not be enough. Verbal warnings are legally sufficient in some situations, though harder to prove later. The warning has to match the hazard. A small “caution” sign at the entrance of a building does not adequately warn about a collapsed stairway in the back.
For recurring hazards, fixing the condition is often smarter than warning about it. A sign next to a permanently uneven floor may reduce liability, but a jury will wonder why the owner never repaired the floor. Courts look at what a reasonable owner would do, and reasonable owners fix problems when the cost of repair is modest relative to the risk of injury.
Employer Warnings About Hazardous Chemicals
Florida employers also have to comply with federal OSHA rules that impose their own duty to warn. The Hazard Communication Standard requires every employer that uses hazardous chemicals to maintain a written hazard communication program, label every container of hazardous material in the workplace, keep Safety Data Sheets accessible during every shift, and train workers on the dangers of the chemicals they handle.4Occupational Safety and Health Administration. Hazard Communication Standard 29 CFR 1910.1200 Labels must be legible, in English, and displayed on each container or available in the immediate work area.
Training is not a one-time obligation. Employers have to provide it when a worker first starts and again whenever a new chemical hazard enters the workplace. The training has to cover how to detect the presence of hazardous chemicals, the health and physical risks of exposure, and the protective measures employees should use. Employers who fall short face OSHA citations and fines, and an injured worker may use the failure as evidence in a personal injury claim.
Suing When the Warning Never Came
A failure-to-warn lawsuit is a negligence claim. The injured person has to prove four things: that the defendant owed a legal duty to warn, that the defendant failed to fulfill that duty, that the failure directly caused the injury, and that the injury produced real damages. Damages typically include medical costs, lost income, and compensation for pain and suffering.
Each element has to hold. A property owner who knew about a hazard and said nothing clearly breached the duty, but the claim still fails if the injury would have happened anyway. A therapist who neglected to contact law enforcement about a credible threat has breached the statutory duty, but the plaintiff still has to show that a timely report would have prevented the harm.
How the 2023 Tort Reform Changed the Math
Florida overhauled its negligence framework in 2023, and the change hits failure-to-warn plaintiffs hard. Under the old system, Florida followed a pure comparative negligence model that allowed an injured person to recover some damages regardless of how much the injury was their own fault. That is no longer the law. Under Florida Statute 768.81(6), any party found more than 50 percent at fault for their own harm cannot recover anything.5The Florida Legislature. Florida Statutes 768.81 – Comparative Fault
In a duty-to-warn case, the defendant will almost always argue that the plaintiff should have noticed the danger themselves. If a jury decides the plaintiff was 51 percent responsible for the injury, the claim is worth zero, no matter how negligent the property owner or other defendant may have been. For injuries from obvious or semi-obvious hazards, this rule can decide the case. One exception: medical malpractice cases are still governed by the old pure comparative negligence standard.
The 2023 reform also shortened the filing deadline. A negligence-based failure-to-warn claim now has to be filed within two years from the date the cause of action accrues, which is typically the date of the injury. This applies to actions accruing after March 24, 2023. Wrongful death claims arising from a failure to warn carry the same two-year deadline. Product-related injury claims have a longer window: an action based on the design, manufacture, or sale of a product must be filed within four years.6The Florida Legislature. Florida Statutes 95.11 – Limitations Other Than for the Recovery of Real Property
Missing these deadlines almost always means losing the right to sue entirely. Courts rarely grant exceptions, and the two-year clock catches people off guard because the old four-year deadline was in place for decades. If you think you have a failure-to-warn claim in Florida, the filing deadline is the first thing to check.
