Until March 2023, Florida was one of only a handful of states that followed pure comparative negligence — a legal doctrine that allowed injury victims to recover compensation regardless of how much fault they shared for an accident, as long as another party was at least partially responsible. A plaintiff who was 90% at fault could still recover 10% of their damages from the remaining party.

That changed dramatically with HB 837. Florida now follows modified comparative negligence — and the modification is a hard bar. If a jury determines that you were more than 50% at fault for the accident that caused your injuries, you recover nothing. Zero. The change has significant implications for how personal injury cases are valued, litigated, and negotiated in Florida.

What Is Comparative Negligence?

Comparative negligence is the legal framework that determines how fault is divided when more than one party’s conduct contributed to an accident. Almost all states use some form of comparative negligence — the question is what happens when the plaintiff shares fault.

Under pure comparative negligence (the old Florida rule), fault was purely proportional. A plaintiff 80% at fault could recover 20% of their damages. Under modified comparative negligence — which most states use, and which Florida now uses — there is a threshold above which recovery is barred entirely.

Florida’s New Rule: The 51% Bar

Under the modified comparative negligence standard adopted by HB 837 (effective March 24, 2023), a plaintiff in a Florida personal injury case is barred from recovering any damages if they are found to be more than 50% at fault — that is, 51% or more. If the jury assigns fault as 50/50, the plaintiff can still recover 50% of their damages. If the jury finds the plaintiff 51% at fault, the plaintiff recovers nothing.

The Threshold: 50% or less fault: you recover damages reduced by your percentage of fault. 51% or more fault: you are barred from recovery entirely. The difference between 50% and 51% is the difference between a substantial settlement and zero compensation.

How This Change Affects Real-World Claims

Insurance Companies Now Fight Harder on Fault

The modification creates a powerful incentive for insurance companies to argue aggressively that the plaintiff was 51% or more at fault — because if they succeed, the insurer pays nothing rather than a reduced amount. Before the change, disputing fault was primarily a tool to reduce the payout. Now, it can eliminate it entirely. This makes thorough accident investigation and strong liability arguments more important than ever in Florida personal injury cases.

Cases Involving Shared Fault Are More Complex

Accidents where fault is genuinely shared — a driver who changed lanes without signaling and a driver who was slightly speeding; a pedestrian crossing mid-block and a driver who ran an amber light; a cyclist who failed to signal and a driver who turned without checking for cyclists — now involve significantly higher stakes. A jury’s fault allocation in a gray-area case determines not just how much is recovered but whether anything is recovered at all.

Comparative Fault Now Affects Pre-Trial Settlement Dynamics

Before trial, both sides must now factor the modified comparative negligence rule into their assessment of what a case is worth. An insurer who could previously offer a token reduction for shared fault now has an argument to offer zero if they can build a plausible case that the plaintiff was primarily responsible. This changes settlement negotiations in ways that favor defendants — and that make strong legal representation for plaintiffs more important.

How Fault Is Determined in Florida Personal Injury Cases

Fault in a Florida personal injury case is typically determined in one of two ways: through settlement negotiation (where the parties agree on a fault allocation) or through jury verdict (where a jury assigns percentages of fault). The jury’s fault determination is made after hearing all of the evidence — which includes witness testimony, physical evidence, expert accident reconstruction, video footage, and argument from attorneys on both sides.

Before the modified comparative negligence rule, plaintiffs’ attorneys needed to establish that the defendant was at fault — period. Now, plaintiffs’ attorneys must also defend against fault attribution to their own client. This makes the quality of the investigation and the strength of the liability presentation even more consequential.

Exceptions — The Medical Malpractice Distinction

It is worth noting that Florida’s HB 837 maintained pure comparative negligence for medical malpractice cases. In medical malpractice, a plaintiff who is 90% at fault can still recover 10% of their damages. The 51% bar applies to personal injury claims generally — car accidents, slip and falls, premises liability, products liability — but not to medical malpractice. The distinction is important for cases that involve elements of both general negligence and medical care.

Why You Need Experienced Representation Under Florida’s New Law

The 2023 comparative negligence change made the stakes in Florida personal injury cases higher for injured plaintiffs. Strong representation — thorough investigation, persuasive liability evidence, credible expert testimony, and aggressive litigation when necessary — is the difference between a full recovery and no recovery when fault is contested.

Howard M. Hughes’ background as a former insurance adjuster and claims manager gives Hughes and Barnard Law Firm a unique perspective on how insurance companies will attempt to attribute fault to plaintiffs under the new law. We anticipate those arguments and build our cases to counter them from the outset.
