The cutover, and why the date of accrual is everything

Florida had been a pure-comparative state since 1973 under Hoffman v. Jones. For 50 years a Florida claimant could recover regardless of fault percentage. HB 837 replaced that with a 51% bar for most negligence actions.

Pre-cutover (accidents before Mar 24, 2023)

Pure comparative

Recovery at any percentage of fault, reduced proportionally. A 60%-at-fault claimant on a $100K case recovers $40K.

Post-cutover (accidents from Mar 24, 2023)

Modified 51% bar

Recovery only when fault is 50% or less. Above 50% you are barred entirely. A 60%-at-fault claimant on a $100K case recovers $0.

The text of HB 837 ties applicability to when the cause of action accrued, not when suit is filed. Medical-negligence cases were expressly carved out and continue under pure comparative regardless of accrual date.

Worked examples: what changes at the cutover

Same facts; different accident dates. The cliff effect of the new 51% bar is visible.

Medical-negligence claim (any date), you 60% at fault, damages $100KN/A$40,000 — carve-out keeps pure comparative

How Florida adjusters use the new rule

The 51% bar gives Florida insurers a hard lever they did not have before March 24, 2023. In any case where the adjuster can credibly argue your fault is just over 50%, the entire claim disappears.

Emphasize speed

Any speed at or above the limit gets called out, even when within the prevailing flow of traffic.

Cabin distractions

Phone visible, food, passengers — anything that can be characterized as inattention.

Push for recorded statements

Early calls before counsel is retained, with leading questions designed to elicit admissions of partial fault.

Pre-existing conditions

Attribute the injury to your medical history rather than the accident to reduce the value of treatment claims.

Defense: do not give a recorded statement to the at-fault driver’s insurer. Document everything contemporaneously, and consult a Florida attorney before agreeing to any percentage of fault.

FAQ: Partly at Fault in Florida

Common claimant questions about the post-HB 837 regime.

Can I still sue in Florida if I was partly at fault?

It depends on when your accident occurred and how much fault is attributed to you. For accidents that accrued on or after March 24, 2023, Florida applies a 51% bar: you can recover only if your fault is 50% or less. Above 50% you are barred entirely. For accidents that accrued before that date, the old pure-comparative rule applies: you can recover at any percentage of fault with damages reduced proportionally. Medical-negligence cases follow the older pure-comparative rule regardless of accrual date.

What changed under House Bill 837?

House Bill 837 made several pro-defendant changes effective March 24, 2023. The two biggest changes affecting partly-at-fault claimants: (1) Florida switched from pure comparative fault to a modified 51% bar under Fla. Stat. § 768.81, and (2) the general personal injury statute of limitations was cut from four years to two years under Fla. Stat. § 95.11(4)(a). Both changes apply only to causes of action that accrued on or after the effective date.

My accident was before March 24, 2023 but I have not filed yet. Which rule applies?

The rule that applies is determined by when the cause of action accrued, not when you file. For pre-March-24-2023 accidents, you should be under the older pure-comparative rule and the four-year statute of limitations. But the older four-year deadline still runs against you. An accident on March 23, 2023 would have had to be filed by March 23, 2027 under the older statute of limitations. Confirm with a Florida attorney before relying on any of this.

Why is the medical-negligence carve-out important?

Medical-malpractice claims in Florida remain under pure comparative negligence even after HB 837. If you suspect medical care contributed to your injury, the analysis is different from an ordinary auto or premises case. The two-year statute of limitations changes also did not apply to medical-malpractice claims, which have their own pre-existing deadlines under Fla. Stat. § 95.11(5)(a).

How will the Florida insurance adjuster use the new 51% bar against me?

In any disputed-liability case, Florida adjusters now have a strong incentive to argue your fault is just over 50%. Crossing that line eliminates the entire claim, so even a small dispute about percentage can swing the outcome from a substantial recovery to zero. This is a major shift from the pure-comparative regime, where the adjuster could only push for percentage reductions, not elimination. Expect adjusters to emphasize any contributing factor on your side and to push for early recorded statements.
