Comparative fault.

(1) DEFINITIONS.—As used in this section, the term:

(a) “Accident” means the events and actions that relate to the incident as well as those events and actions that relate to the alleged defect or injuries, including enhanced injuries.

(b) “Economic damages” means past lost income and future lost income reduced to present value; medical and funeral expenses; lost support and services; replacement value of lost personal property; loss of appraised fair market value of real property; costs of construction repairs, including labor, overhead, and profit; and any other economic loss that would not have occurred but for the injury giving rise to the cause of action.

(c) “Negligence action” means, without limitation, a civil action for damages based upon a theory of negligence, strict liability, products liability, professional malpractice whether couched in terms of contract or tort, or breach of warranty and like theories. The substance of an action, not conclusory terms used by a party, determines whether an action is a negligence action.

(d) “Products liability action” means a civil action based upon a theory of strict liability, negligence, breach of warranty, nuisance, or similar theories for damages caused by the manufacture, construction, design, formulation, installation, preparation, or assembly of a product. The term includes an action alleging that injuries received by a claimant in an accident were greater than the injuries the claimant would have received but for a defective product. The substance of an action, not the conclusory terms used by a party, determines whether an action is a products liability action.

(2) EFFECT OF CONTRIBUTORY FAULT.—In a negligence action, contributory fault chargeable to the claimant diminishes proportionately the amount awarded as economic and noneconomic damages for an injury attributable to the claimant’s contributory fault, but does not bar recovery, subject to subsection (6).

(3) APPORTIONMENT OF DAMAGES.—In a negligence action, the court shall enter judgment against each party liable on the basis of such party’s percentage of fault and not on the basis of the doctrine of joint and several liability.

(a)1. In order to allocate any or all fault to a nonparty, a defendant must affirmatively plead the fault of a nonparty and, absent a showing of good cause, identify the nonparty, if known, or describe the nonparty as specifically as practicable, either by motion or in the initial responsive pleading when defenses are first presented, subject to amendment any time before trial in accordance with the Florida Rules of Civil Procedure.

2. In order to allocate any or all fault to a nonparty and include the named or unnamed nonparty on the verdict form for purposes of apportioning damages, a defendant must prove at trial, by a preponderance of the evidence, the fault of the nonparty in causing the plaintiff’s injuries.

(b) In a products liability action alleging that injuries received by a claimant in an accident were enhanced by a defective product, the trier of fact shall consider the fault of all persons who contributed to the accident when apportioning fault between or among them. The jury shall be appropriately instructed by the trial judge on the apportionment of fault in products liability actions where there are allegations that the injuries received by the claimant in an accident were enhanced by a defective product. The rules of evidence apply to these actions.

(4) APPLICABILITY.—This section does not apply to any action brought by any person to recover actual economic damages resulting from pollution, to any action based upon an intentional tort, or to any cause of action as to which application of the doctrine of joint and several liability is specifically provided by chapter 403, chapter 498, chapter 517, chapter 542, or chapter 895.

(5) MEDICAL MALPRACTICE.—Notwithstanding anything in law to the contrary, in an action for damages for personal injury or wrongful death arising out of medical malpractice, whether in contract or tort, if an apportionment of damages pursuant to this section is attributed to a teaching hospital as defined in s. 408.07, the court shall enter judgment against the teaching hospital on the basis of such party’s percentage of fault and not on the basis of the doctrine of joint and several liability.

(6) GREATER PERCENTAGE OF FAULT.—In a negligence action to which this section applies, any party found to be greater than 50 percent at fault for his or her own harm may not recover any damages. This subsection does not apply to an action for damages for personal injury or wrongful death arising out of medical negligence pursuant to chapter 766.
