For negligence cases filed after March 24, 2023, a person found more than 50 percent at fault generally recovers nothing. At 50 percent or less, damages are reduced by that share. House Bill 837 made that modified comparative negligence rule the central fight in most crash and premises cases, because pushing an injured person over the halfway line ends the claim entirely rather than merely discounting it.
That filing-date trigger is different from the two-year statute of limitations, which usually runs from the date of injury. Medical malpractice claims are excluded from this modified rule and follow their own fault framework.
How Modified Comparative Negligence Works
Florida previously applied pure comparative negligence: you could recover even if you were mostly at fault, with damages cut by your percentage. The modified rule is harsher at the top end. A finding of 51 percent fault against you is a total bar in the usual negligence case. Insurers know that, and opening settlement positions often assume a fault split that favors ending the claim.
The rule shows up in every car accident with disputed lane position, every truck crash where the carrier argues the passenger vehicle braked suddenly, and every pedestrian claim where lighting, crosswalk use, or clothing color becomes a liability argument. It also appears in many slip and fall cases where the defense argues the injured person should have seen the hazard.
Where Insurers Push The Number
Adjusters look for any fact that can be spun as shared blame: speed estimates, following distance, phone use, failure to wear a seatbelt in damages arguments, and “you should have seen them” theories at intersections. In truck cases, the company’s rapid-response team often arrives while you are still in the emergency room. In pedestrian cases, the defense leans on visibility and path of travel.
None of that means the insurer’s first number is correct. It means the fight starts early, and recorded statements given without counsel are frequently the exhibit used to inflate your percentage later. Locking down physical and electronic evidence before the narrative hardens is what moves the number.
Local Roads And Local Juries
Fault arguments are heard by juries drawn from the venue where the case is filed. A disputed merge on I-275 looks different to a Tampa jury than a port-corridor truck conflict does in Jacksonville. Local driving norms, congestion patterns, and how the crash corridor is known in the community all influence how a percentage lands.
What To Do When Fault Is Disputed
- Do not give a recorded statement to the other side’s insurer
- Preserve photos, the police report number, and witness contacts the same day
- Get medical care promptly so the defense cannot argue the injury was minor or unrelated
- Have counsel send preservation demands when commercial vehicles, cameras, or telematics are involved
A free case review identifies the evidence that moves the fault percentage and the arguments the insurer is likely to make. It does not invent a number in place of that record.
How This Fits With Other Florida Rules
The 51 percent bar sits beside the two-year filing deadline and beside no-fault PIP limits. You can lose PIP by missing the fourteen-day treatment window and still face a hard fault fight on the liability claim. You can also clear the fault bar and still need UM coverage when the at-fault driver carried too little bodily injury insurance. The rules stack; none of them replaces the others.
Frequently Asked Questions
What is Florida’s 51 percent fault rule?
In most negligence cases filed after March 24, 2023, a person found more than 50 percent at fault recovers nothing. At 50 percent or less, damages are reduced by that share of fault. Medical malpractice is excluded from this modified rule.
Does the rule turn on the injury date or the filing date?
The modified comparative negligence rule generally applies to cases filed after March 24, 2023. That is a different trigger from the two-year statute of limitations, which usually runs from the date of injury.
Can I still recover if I was partly at fault?
Yes, if you are found 50 percent or less at fault. Damages are reduced by your share. The dangerous line is anything above half, which generally ends the claim.
Why do insurers argue about fault so early?
Because under the modified rule, pushing an injured person over 50 percent ends the claim rather than merely reducing it. Early recorded statements and missing evidence make that push easier.
