11.1 Tort Law Fundamentals, the Elements of Negligence and Defenses

Quick Answer: A civil tort claim requires proving four fundamental elements: duty owed, breach of duty, proximate cause, and damages. Under Florida's landmark tort reform enacted through House Bill 837 (HB 837), effective March 24, 2023, Florida transitioned from a pure comparative negligence state to a modified comparative negligence system with a 51% bar (F.S. § 768.81). If a plaintiff is found to be greater than 50% at fault, they are completely barred from recovering any damages (with an exception for medical malpractice). HB 837 also cut Florida's general negligence statute of limitations under F.S. § 95.11 from 4 years down to 2 years.

1. Foundational Tort Law & The Four Elements of Negligence

In casualty insurance, a tort is a civil wrong—other than a breach of contract—that causes harm, injury, or economic loss to another person or property, resulting in legal liability. While torts can be intentional (such as battery, assault, or defamation) or strict (liability without fault), the vast majority of casualty claims handled by Florida claims adjusters arise from negligence.

Negligence is legally defined as the failure to exercise the degree of reasonable care that an ordinarily prudent person would have exercised under the same or similar circumstances. To establish actionable negligence against an insured party under Florida law, a plaintiff must prove four mandatory legal elements by a preponderance of the evidence:

1. Duty Owed ──> 2. Breach of Duty ──> 3. Proximate Cause ──> 4. Damages / Injury

1. Duty Owed

The plaintiff must prove that the defendant owed a recognized legal obligation to conform to a specific standard of conduct to protect the plaintiff against unreasonable risks of harm. In general casualty claims, this standard is the reasonable prudent person standard. In premises liability claims, the legal duty owed depends upon the claimant's legal classification under Florida law:

• Invitee (Public / Business): The highest duty of care. The property owner owes a duty to maintain the premises in a reasonably safe condition and to inspect the property to discover and warn of hidden, dangerous conditions that the owner knew or should have known existed.
• Licensee (Uninvited / Social Guest): The owner owes a duty to refrain from wanton negligence or willful misconduct and must warn of known concealed dangers not readily observable.
• Trespasser (Undiscovered): The owner owes only a minimal duty to refrain from intentional, willful, or wanton injury. However, under the attractive nuisance doctrine, property owners owe a heightened duty of care to protect child trespassers from dangerous artificial conditions on the land (such as unfenced swimming pools or construction equipment).

2. Breach of Duty

The plaintiff must demonstrate that the defendant failed to conform to the required standard of care. Breach occurs through an act of commission (doing something a prudent person would not have done, such as driving 85 mph in a thunderstorm) or an act of omission (failing to perform an act that a prudent person would have done, such as failing to clean up a recognized supermarket liquid spill).

3. Proximate Cause (Causation)

The breach of duty must be both the cause-in-fact and the legal (proximate) cause of the plaintiff's injuries:

• Cause-in-Fact ("But-For" Test): The injury would not have occurred but for the defendant's negligent conduct.
• Legal / Proximate Cause: The injury must be the natural, direct, and foreseeable consequence of the defendant's breach, operating through a continuous, unbroken chain of events. Under Florida law, if an independent, unforeseeable event breaks the chain of causation, it is classified as an intervening superseding cause, which relieves the initial defendant of legal liability.

4. Damages (Actual Injury or Financial Loss)

The plaintiff must suffer actual, demonstrable physical bodily injury, property damage, or quantifiable economic loss. Negligence without demonstrable damages cannot sustain a civil lawsuit or an insurance liability payout.

Proving Duty and Breach in Practice

A liability adjuster rarely argues about whether a duty existed in the abstract; the fight is over the standard of care and whether the insured met it.

• The Reasonable Person Standard. The default measure is what a reasonably careful person would have done under the same circumstances. It is objective: the insured's good intentions, inexperience, or personal habits do not lower the bar.
• Elevated and Special Standards. Professionals are measured against the skill and knowledge of a reasonably competent practitioner in the same field. Children are generally measured against a child of like age, intelligence and experience — except when engaged in an adult activity such as driving. Common carriers owe a heightened duty to passengers.
• Premises Liability Classifications. Florida still sorts entrants into invitees (owed a duty of reasonable care plus a duty to inspect and warn of known or discoverable dangers), licensees (owed a duty to warn of known dangers and to refrain from wanton injury), and trespassers (owed only a duty to refrain from willful or wanton harm, with a narrow attractive nuisance doctrine for child trespassers drawn by an artificial condition). Slip-and-fall claims against a business have their own statutory proof rule: under F.S. § 768.0755, the claimant must prove the business had actual or constructive knowledge of the transitory foreign substance, shown by how long the condition existed or that it occurred with regularity and was foreseeable.

Two Doctrines That Shift the Proof Burden

• Negligence Per Se. Where a statute or ordinance was enacted to protect a class of people from a particular type of harm, violating that statute can establish breach as a matter of law. A driver who runs a red light and injures a pedestrian has violated a traffic statute designed to protect exactly that class from exactly that harm.
• Res Ipsa Loquitur ("the thing speaks for itself"). Where the injury is of a kind that ordinarily does not occur without negligence, the instrumentality was in the defendant's exclusive control, and the plaintiff did not contribute to it, the fact of the accident supports an inference of negligence even without direct proof. A surgical instrument left inside a patient is the classic example.
