Florida Affirmative Defenses List: Contract, Tort, and Timing

A Florida defendant can defeat or reduce a civil claim by raising an affirmative defense, which concedes the plaintiff’s facts for the sake of argument but offers a separate legal reason the defendant should not be liable. The Florida affirmative defenses list in Rule of Civil Procedure 1.110(d) names close to twenty of them: accord and satisfaction, arbitration and award, assumption of risk, contributory negligence, discharge in bankruptcy, duress, estoppel, failure of consideration, fraud, illegality, injury by fellow servant, laches, license, payment, release, res judicata, statute of frauds, statute of limitations, and waiver.1The Florida Bar. Florida Rules of Civil Procedure The list is illustrative rather than closed. Comparative negligence, sovereign immunity, unclean hands, and other defenses developed through case law must also be pleaded affirmatively even though the rule does not name them.

Pleading the Defense on Time

Rule 1.110(d) requires a defendant to state every affirmative defense in the initial answer to the complaint, along with a short, plain statement of the facts supporting it. The defendant carries the burden of proof on each defense raised. Leaving a defense out of the answer generally waives it, and Florida judges enforce that rule strictly. Rule 1.190 allows amendment to add a forgotten defense, but once the plaintiff has served a responsive pleading the defendant needs leave of court, and requests that come late or would prejudice the plaintiff are often denied.1The Florida Bar. Florida Rules of Civil Procedure The practical rule is simple: identify every plausible defense before filing the answer.

Contract-Based Defenses

Several defenses on the list respond to breach-of-contract claims by attacking either the agreement’s validity or the plaintiff’s right to still sue on it.

Accord and satisfaction argues that the parties resolved the disputed obligation through a new agreement and the defendant performed it. Payment is the simpler cousin: the defendant proves they already paid or performed what the contract required. Release relies on a signed written document in which the plaintiff gave up the right to sue over the dispute at issue; settlement agreements and liability waivers are common examples, and courts read release language carefully.

Statute of frauds renders a contract unenforceable because it was never put in writing when Florida law required one. Under Florida Statutes section 725.01, contracts for the sale of land, agreements that cannot be performed within one year, promises to pay another person’s debt, and agreements made in consideration of marriage must be in writing and signed by the party being held to them.2Florida Senate. Florida Statutes Chapter 725 Section 01 Florida’s version of the Uniform Commercial Code adds a writing requirement for sales of goods worth $500 or more.3Florida Senate. Florida Code 672-201 – Formal Requirements Statute of Frauds

Fraud, raised as a defense, asserts that the defendant was induced to sign by a material misrepresentation the plaintiff knew to be false (or had no basis for believing true) and that the defendant relied on to their detriment. Proof makes the contract voidable. Duress argues that wrongful pressure destroyed the defendant’s ability to choose freely; the question is whether the threat would overcome a reasonable person’s free will and whether any realistic alternative existed. Economic duress can qualify when one party deliberately exploits the other’s financial vulnerability, though ordinary hard bargaining does not. Failure of consideration argues that the plaintiff never delivered what they promised, so the defendant received nothing of value in exchange for their own obligations.

Negligence and Personal Injury Defenses

Comparative Fault

Florida’s modified comparative fault rule appears in nearly every personal injury answer. Under Florida Statutes section 768.81, a plaintiff found more than 50 percent at fault for their own harm recovers nothing.4The Florida Legislature. Florida Statutes 768.81 – Comparative Fault If the plaintiff’s share is 50 percent or less, the award is reduced in proportion. A plaintiff found 30 percent at fault for a $100,000 injury recovers $70,000.

Medical negligence claims under Chapter 766 are the exception. The greater-than-50-percent bar does not apply, and the court uses pure comparative fault, reducing the recovery by the plaintiff’s percentage of fault with no absolute cutoff.4The Florida Legislature. Florida Statutes 768.81 – Comparative Fault

Assumption of Risk

Assumption of risk applies when the plaintiff voluntarily and knowingly exposed themselves to a recognized danger, as with injuries sustained during normal play in a contact sport. The defendant must show the plaintiff understood the specific risk and chose to encounter it anyway. A signed waiver strengthens the defense, but voluntary participation in an obviously dangerous activity can suffice on its own.

Failure to Mitigate Damages

Even a liable defendant can argue that the plaintiff failed to take reasonable steps to limit their own losses. A plaintiff who refuses recommended medical treatment that would have reduced the severity of an injury, or a contracting party who sits idle instead of seeking a substitute supplier, has not mitigated. The defendant bears the burden of showing reasonable mitigation was possible and the plaintiff neglected it.

Equitable Defenses

These defenses matter most when the plaintiff seeks a non-monetary remedy such as an injunction, specific performance, or rescission. A court sitting in equity has broad discretion to deny relief when the plaintiff’s own conduct makes it unfair to grant.

Laches is the equitable counterpart to a limitations period. The defendant must show the plaintiff knew about the claim, waited an unreasonable time to bring it, and the delay caused prejudice. A plaintiff with a good explanation for the delay, such as ongoing negotiations or lack of information, can defeat the defense.

Unclean hands bars equitable relief when the plaintiff engaged in unfair or dishonest conduct connected to the same dispute. The misconduct need not be criminal, but it must relate to the subject matter of the lawsuit; unrelated wrongdoing elsewhere does not count. When it applies, the defense is a complete bar regardless of the merits of the underlying claim.

Equitable estoppel prevents a plaintiff from asserting a position that contradicts earlier conduct the defendant relied on. Florida’s standard jury instructions require proof that the plaintiff acted, spoke, or stayed silent when they had a duty to speak; that the defendant relied in good faith; and that the reliance caused the defendant to change position for the worse.5The Florida Bar.

Timing and Preclusion Defenses

Statute of Limitations

Florida Statutes section 95.11 sets the deadlines for filing civil claims. Once the period runs, the claim is time-barred regardless of its merits. The most common Florida limitations periods are:

The clock starts when the cause of action accrues, meaning when the injury occurs or, in fraud cases, when the plaintiff discovered or should have discovered the fraud. Because limitations is one of the most powerful defenses available, waiving it by leaving it out of the answer is especially costly.

Statute of Repose

A statute of repose runs from the defendant’s last act rather than from the plaintiff’s injury. Florida presumes most products have a useful life of 10 years, and no products liability action can be brought once that period expires, even if the injury happens on the final day. Products specifically warranted to last longer get a repose period matching the warranty or 12 years after delivery, whichever is later. Commercial aircraft, large vessels, railroad equipment, and improvements to real property are exempt from the products repose limit.8The Florida Legislature. Florida Statutes 95.031 – Computation of Time

Res Judicata

Res judicata, also called claim preclusion, blocks a plaintiff from relitigating a dispute that already produced a final judgment on the merits. The defense requires the same parties (or their legal equivalents), the same cause of action, and a final judgment. Once a court resolves a dispute, the losing side does not get another chance at the same claim.

Lack of Subject Matter Jurisdiction

This defense argues that the court lacks authority to hear the type of case the plaintiff filed. Unlike most affirmative defenses, it cannot be waived. A court can raise the problem on its own at any stage, and a defendant who notices a jurisdictional defect after answering can still bring it up.

Sovereign Immunity

When the defendant is a government entity, sovereign immunity adds protection that private defendants do not have. Florida Statutes section 768.28 waives immunity for tort claims against the state and its agencies, but only partially. Recovery is capped at $200,000 per person and $300,000 per incident, and a plaintiff who wins a judgment above those caps must petition the Legislature for a claims bill to collect the excess.9The Florida Legislature. Florida Statutes 768.28 – Waiver of Sovereign Immunity in Tort Actions

The statute also shields government entities from punitive damages and prejudgment interest entirely. The immunity covers state agencies, counties, municipalities, and employees acting within the scope of their duties. Plaintiffs must give the appropriate agency written notice and wait out a statutory period before filing, and failing to follow those steps supports a procedural dismissal.9The Florida Legislature. Florida Statutes 768.28 – Waiver of Sovereign Immunity in Tort Actions

If the Case Is in Federal Court

A case filed in federal court in Florida follows Federal Rule of Civil Procedure 8(c), not the state rule. The federal list is nearly identical and includes accord and satisfaction, assumption of risk, duress, estoppel, fraud, laches, payment, release, res judicata, statute of frauds, statute of limitations, and waiver.10Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading The pleading obligation is the same: raise it in the answer or lose it. The one meaningful difference is subject matter jurisdiction, which in federal court can be raised at any point, including on appeal.11Legal Information Institute.
