Florida Comparative Negligence Explained

Under HB 837, Florida switched from pure comparative negligence to a modified system with a 51% bar. The rule is straightforward: if you bear 50% or less of the total fault for the accident, your damages are reduced by your fault percentage. If you bear 51% or more of the fault, you are completely barred from any recovery.

The math works like this. If your total damages are $200,000 and you are found 20% at fault, you recover $160,000. At 40% fault, you recover $120,000. At 50% fault — the maximum allowed — you recover $100,000. But at 51% fault, you recover $0. That one percentage point is the difference between a substantial recovery and nothing. The 51% threshold creates a hard cliff with enormous financial consequences.

This system applies to all negligence-based personal injury claims in Florida arising from accidents on or after March 24, 2023, including car accidents, truck accidents, motorcycle crashes, pedestrian accidents, slip and falls, and premises liability. For accidents before that date, the old pure comparative negligence system still applies — you could recover at any fault level, with your damages reduced proportionally.

Example 1: You are rear-ended at a red light. The other driver was texting, but your brake lights were out. A jury awards $150,000 in damages and assigns you 10% fault for the brake light issue. You recover $135,000. Under Florida's modified system, a small fault assignment results in a proportional reduction — but you still receive the vast majority of your award.

Example 2: You make an unsafe lane change on I-275 and collide with a speeding driver. A jury awards $200,000 and assigns you 60% fault. You recover $0. Before HB 837, you would have recovered $80,000 under pure comparative negligence. The 51% bar eliminates your entire claim. This is the most significant practical change — cases where the plaintiff bears majority fault now result in zero recovery.

Example 3: A T-bone collision at an intersection where both drivers claim the other ran the light. A jury awards $300,000 and assigns you 50% fault. You recover $150,000. At 50% fault, you are exactly at the threshold and can still recover. But if the jury had assigned you 51% — just one percentage point more — you would recover nothing. Evidence quality determines which side of the line you land on.

Example 4: A multi-vehicle accident on I-4 involving three drivers. The jury assigns 45% fault to Driver A, 35% to Driver B, and 20% to you. On a $400,000 verdict, you recover $320,000 (reduced by your 20% fault). But if your fault had been 51% in a two-car accident, the other driver would owe you nothing regardless of the total damages. In multi-vehicle cases, fault is spread across more parties, which can work in your favor by keeping your percentage below the 51% bar.

Before March 24, 2023, Florida used pure comparative negligence. This was one of the most claimant-friendly systems in the country — you could recover damages even if you were 99% at fault. A plaintiff at 80% fault on a $200,000 verdict would recover $40,000. Pure comparative negligence meant that fault was always proportional and never eliminated your claim entirely.

After HB 837, that safety net is gone. The 51% bar means Florida now operates like Ohio, Illinois, and Indiana — states that have long used modified comparative negligence. Arizona and Missouri remain the most claimant-friendly states in our coverage area, still using pure comparative negligence with no fault bar.

The transition date matters: HB 837's modified comparative negligence applies only to causes of action accruing on or after March 24, 2023. If your accident happened on March 23, 2023, pure comparative negligence applies to your case. If it happened on March 24, 2023, the new 51% bar applies. This one-day difference can mean the difference between recovering damages at 60% fault and recovering nothing.

Comparative fault is a question of fact for the jury. The jury examines all available evidence and assigns a specific percentage of fault to each party involved in the accident. Those percentages must total 100% across all parties. In bench trials (no jury), the judge makes the fault determination.

Florida allows fault to be allocated to all parties, including nonparties. A defendant can argue that a person not named in the lawsuit is partially at fault, which effectively reduces the named defendants' shares. The Fabre doctrine (from Fabre v. Marin, 1993) requires that all potential tortfeasors be placed on the verdict form so the jury can allocate fault among them. This means defendants will actively seek to spread fault to other parties — including the plaintiff — to minimize their own share.

Police accident reports are often the starting point for fault analysis in Florida. The responding officer's determination, driver statements, citations issued, and noted traffic violations all factor into the fault determination. But police reports are just one piece of evidence — the jury also weighs witness testimony, dashcam footage, traffic camera recordings, security camera footage, phone records showing distracted driving, vehicle black box data, accident reconstruction expert analysis, and physical evidence such as skid marks and debris patterns.

Because Florida's 51% bar creates an all-or-nothing threshold, evidence quality is more important than ever. The difference between 49% fault and 51% fault is not a small proportional adjustment — it is the difference between a substantial recovery and zero. Every piece of evidence that moves your fault percentage one direction or the other has outsized impact near the threshold.

Key evidence types include: police accident reports and citations issued, witness statements and contact information collected at the scene, dashcam and surveillance camera footage, photographs of vehicle damage and the accident scene, medical records establishing injury causation and severity, phone records (to establish distracted driving), vehicle event data recorder (black box) data, and physical evidence such as skid marks, debris patterns, and road conditions.

Preserving evidence starts at the accident scene. Photograph everything — vehicle damage, road conditions, traffic signals, skid marks, and the surrounding area. Get contact information for every witness. Do not move vehicles until photos are taken (unless safety requires it). Request the police report number before leaving the scene. In post-HB 837 Florida, where the 51% bar means a single percentage point can eliminate your entire claim, thorough evidence preservation at the scene is the single most valuable step you can take to protect your recovery.

Insurance adjusters in Florida now have a powerful weapon that did not exist before HB 837: the ability to argue that your fault exceeds 50%, which would eliminate their obligation to pay anything. Before the reform, adjusters negotiated over how much to reduce the payout. Now, they negotiate over whether to pay at all.

Expect adjusters to aggressively assign fault to you in any case where the facts are even slightly ambiguous. A texting driver who rear-ends you will have their adjuster argue you braked suddenly or were in an improper lane. A slip-and-fall victim will face arguments about distraction, improper footwear, or failure to notice an obvious hazard. The adjuster's goal is not necessarily to prove 51% fault at trial — it is to create enough doubt about fault to pressure you into accepting a lower settlement.

The best defense against 51% bar arguments is strong, early evidence. Hire an attorney before giving any statements. Preserve all physical evidence from the scene. Obtain the police report immediately. Get medical treatment promptly and document every visit. The more evidence you have proving the other party's fault, the harder it is for the adjuster to credibly argue that you exceeded the 51% threshold.

Florida is a no-fault state for auto insurance, meaning your own Personal Injury Protection (PIP) coverage pays for your initial medical expenses regardless of who caused the accident. PIP covers 80% of medical expenses and 60% of lost wages, up to a $10,000 cap. PIP claims are not affected by comparative negligence because they pay regardless of fault.

But PIP has strict limits. To step outside the no-fault system and file a liability claim against the at-fault driver for full damages (including pain and suffering), you must meet the serious injury threshold: significant and permanent loss of an important bodily function, permanent injury within a reasonable degree of medical probability, significant and permanent scarring or disfigurement, or death. Once you step outside no-fault, the modified comparative negligence rules apply in full — including the 51% bar.

This creates a two-tier system. Your PIP claim pays regardless of fault, but the amounts are limited. If your injuries meet the serious injury threshold and you pursue the at-fault driver, your recovery is subject to comparative negligence reduction and the 51% bar. An injury victim at 51% fault recovers their PIP benefits but nothing beyond that — no compensation for pain and suffering, no additional medical expenses beyond the $10,000 PIP cap, and no recovery for long-term lost wages.
