On March 24, 2023, Governor Ron DeSantis signed House Bill 837 into law, fundamentally changing how fault is assigned and compensation is calculated in Florida personal injury cases. The most significant change was Florida’s shift from a pure comparative negligence system to a modified comparative negligence system with a 51% bar. Under the new rule, codified in Florida Statute § 768.81(6), any person found to be more than 50% at fault for their own injuries is completely barred from recovering any damages. This single change has reshaped the strategy, risk, and outcome of virtually every negligence case filed in Florida since March 2023.
The shift ended a 50-year legal framework. Since 1973, Florida had operated under a pure comparative negligence system that allowed injured persons to recover damages even if they bore the majority of the fault. A plaintiff who was 80% at fault could still recover 20% of their damages from the other responsible party. That system prioritized proportional accountability. The new law replaces proportionality with a hard cutoff: one percentage point of fault above the 50% line eliminates the entire claim, regardless of how severe the injuries are or how negligent the other party was.
What Is Comparative Negligence?
Comparative negligence is the legal principle used to allocate fault among multiple parties in an accident and adjust the injured person’s compensation accordingly. In most accidents, more than one person’s actions contributed to what happened. A driver may have been speeding, but the other driver ran a red light. A pedestrian may have been crossing outside a crosswalk, but the driver was texting. Comparative negligence determines what percentage of fault each party bears and reduces the injured person’s recovery by their share of responsibility.
Before HB 837, Florida’s pure comparative negligence system worked like this: if you were injured in an accident and found 30% at fault, you could recover 70% of your total damages from the other party. If you were 70% at fault, you could still recover 30%. Even a plaintiff who was 99% responsible could recover 1% of their damages.
What Changed Under HB 837?
HB 837 added subsection (6) to Florida Statute § 768.81, which states: in a negligence action, any party found to be greater than 50% at fault for his or her own harm may not recover any damages. This is the 51% bar.
The practical effect is stark. Under the old system, a plaintiff found 60% at fault for an accident involving $200,000 in damages could recover $80,000. Under the new system, that same plaintiff recovers nothing. The entire claim is barred.
The change applies to all negligence actions filed on or after March 24, 2023. Cases filed before that date remain under the pure comparative negligence standard. Florida joined 23 other states that use a 50% threshold model for modified comparative negligence.
What Types of Cases Does the 51% Bar Apply To?
The 51% bar applies to virtually all negligence-based personal injury claims in Florida, including car accidents, truck accidents, motorcycle accidents, pedestrian and bicycle accidents, slip and fall cases, premises liability claims, product liability claims based on negligence, and dog bite cases.
There is one significant exception. Florida Statute § 768.81(6) explicitly states that the 51% bar does not apply to actions for personal injury or wrongful death arising out of medical negligence pursuant to Chapter 766. Medical malpractice claims remain under the pure comparative negligence standard. A patient found 60% at fault in a medical negligence case can still recover 40% of their damages.
How Does the 51% Bar Affect Car Accident Claims?
Insurance companies have always argued comparative fault in car accident cases. Before HB 837, those arguments reduced the plaintiff’s recovery but never eliminated it. Now, a successful argument that the plaintiff was 51% at fault eliminates the claim entirely. This gives insurers a strong incentive to aggressively investigate the plaintiff’s conduct.
Common comparative fault arguments include that the plaintiff was speeding, distracted by a phone, failed to wear a seatbelt (argued to have worsened injuries), made an unsafe lane change, failed to yield, or was impaired. Each argument carries higher stakes under the new system because success does not just reduce the payout; it eliminates it.
For plaintiffs, evidence preservation is more important than ever. Dashcam footage, witness statements, traffic camera recordings, cell phone records, and accident reconstruction analysis can determine whether the plaintiff’s fault stays below or crosses the 50% threshold. The difference between a finding of 49% fault and 51% fault is the difference between receiving compensation and receiving nothing.
How Did HB 837 Change the Statute of Limitations?
HB 837 shortened the statute of limitations for most negligence claims from four years to two years. Under Florida Statute § 95.11, personal injury claims for causes of action accruing after March 24, 2023, must be filed within two years from the date of injury. This shortened deadline compounds the pressure created by the 51% bar.
How Did HB 837 Change Medical Damages Evidence?
Under Florida Statute § 768.0427, for past medical expenses that have been paid, only the amount actually paid (not the amount billed) is admissible as evidence. For future medical expenses, the statute uses formulas tied to Medicare or Medicaid reimbursement rates. A plaintiff whose ER visit was billed at $25,000 but paid at $8,000 by insurance can only present the $8,000 figure. Letters of protection must also be disclosed under the new rules.
How Does the 51% Bar Interact with Florida’s No-Fault System?
PIP benefits under Florida Statute § 627.736 are not affected by the 51% bar because PIP is a no-fault benefit. However, when the injured person’s damages exceed PIP’s $10,000 cap and they pursue a claim against the at-fault driver, the 51% bar applies. For motorcyclists, excluded from PIP entirely, the 51% bar applies from the first dollar of the claim. The helmet non-use argument as comparative fault is particularly dangerous in this context.
How Does Fault Allocation Work When Multiple Parties Are Involved?
In multi-party cases, the court assigns a fault percentage to every party, including the plaintiff. The critical question is always the plaintiff’s own percentage. If three drivers are involved and the jury assigns 30% to the plaintiff, 45% to Driver B, and 25% to Driver C, the plaintiff can recover because 30% does not exceed 50%. If the plaintiff is assigned 55%, they recover nothing from anyone despite the other drivers being collectively 45% at fault.
Defense attorneys have a strategic incentive to shift as much fault as possible onto the plaintiff because pushing the plaintiff above 50% eliminates all defendants’ liability simultaneously.
What Does This Look Like in Practice?
A driver traveling 10 mph over the speed limit is hit by another driver who runs a stop sign. If the jury finds the speeding driver 25% at fault and the stop-sign runner 75% at fault, the speeding driver recovers 75% of damages. Now add that the speeding driver was also on their phone. If the jury assigns 55% fault to the plaintiff for the combination of speeding and phone distraction, the plaintiff recovers nothing, even though the other driver ran a stop sign.
The difference between these two scenarios is not a different accident. It is different evidence. This illustrates why evidence preservation and early legal representation matter more under the modified system.
What Other Changes Did HB 837 Make?
Bad faith insurance reform. Insurers that tender policy limits or make good faith settlement offers within specified timeframes receive greater protection against bad faith claims.
Premises liability presumption. Florida Statute § 768.0706 created a presumption against liability for multifamily properties that implement specific security measures including adequate lighting, cameras, deadbolts, and a CPTED assessment.
One-way attorney fees elimination. HB 837 eliminated one-way attorney fee provisions in many insurance disputes, reducing the financial incentive for litigation against insurers.
These changes, taken together, shifted the overall balance of Florida’s civil justice system in favor of defendants and insurers. For injured persons, the combined effect is a legal environment that demands stronger evidence, faster action, and more careful case selection.
What Should You Do to Protect Your Claim?
The 51% bar makes several practical steps more important than they were before 2023. Document everything at the accident scene. Photographs, video, witness contact information, and dashcam footage are critical because fault percentages are determined based on evidence. Seek medical treatment immediately. Gaps in treatment give insurers ammunition to argue that your injuries are not as severe as claimed. Do not give recorded statements to the other driver’s insurance company without consulting an attorney. Under the new system, the insurer has a direct financial incentive to push your fault above 50%. Act quickly: the two-year statute of limitations leaves less time to build your case.
When Should You Contact an Attorney?
You should consult a personal injury attorney as soon as possible after any accident. The 51% bar and the shortened statute of limitations have raised the stakes for every negligence claim in Florida. An attorney experienced in post-HB 837 litigation understands how to build a case that keeps your fault below the 50% threshold, counters the insurance company’s comparative fault arguments, and maximizes your recovery within the new legal framework.
