Practice Areas: Personal Injury, Insurance Claims
Louisiana changed how shared fault is calculated in injury claims, effective January 1, 2026. Under House Bill 431, signed by Governor Jeff Landry on May 28, 2025, as Act No. 15 of the 2025 Regular Session, Louisiana amended Civil Code article 2323 and adopted a 51% bar modified comparative fault system.
This matters most when fault is disputed, and the percentage could range from 40% to 60%. If your crash happened on or after January 1, 2026, speaking with a New Orleans personal injury lawyer can help you understand how the new rule may apply to your claim.
What Changed in Louisiana on January 1, 2026
Before 2026, Louisiana used pure comparative fault. That system reduced an injured person’s recovery by the percentage of fault, but did not completely cut off recovery.
HB 431 changed that for causes of action arising on or after January 1, 2026. Crashes before that date still fall under the older pure comparative fault rule that Louisiana followed for more than four decades.
Louisiana now follows a model used by roughly 33 other states, where recovery is barred once the plaintiff’s fault reaches a set threshold, commonly 50% or 51%.
How the Old Rule Worked Under Pure Comparative Fault
Under Louisiana’s pre-2026 pure comparative fault rule, an injured person could recover damages even if mostly at fault for the crash.
That was not always the case. Before 1980, Louisiana followed pure contributory negligence. Under that system, even 1% of fault on the part of the plaintiff could block recovery entirely. The 1980 move to pure comparative fault softened that rule. The plaintiff’s share of fault reduced recovery, but there was no cutoff.
So, under the old rule, a plaintiff found 99% at fault could still recover 1% of their damages from a defendant who was 1% at fault.
In practice, Louisiana juries and insurers worked with the understanding that fault reduced the claim’s value, but it did not automatically erase the claim.
How the 51% Bar Works Now
Amended art. 2323 creates a cutoff. If the injured person is 51% or more at fault, they cannot recover damages. If their fault is below 51%, their damages are reduced by their assigned percentage.
The statute says:
“If the degree or percentage of negligence attributable to the person suffering injury, death, or loss is equal to or greater than fifty-one percent, then the person suffering injury, death, or loss shall not be entitled to recover damages.”
The calculation below the cutoff still works the familiar way. If damages are $100,000 and the plaintiff is 20% at fault, recovery is $80,000. If the plaintiff is 49% at fault, recovery is $51,000. At 51% or higher, recovery becomes $0.
The amended article also requires juries to be instructed on the effect of the statute when comparative fault is submitted to them. In other words, jurors will know that assigning 51% fault to the plaintiff ends the claim.
What the New Rule Means for Close-Call Crashes
The new rule matters most when both sides have facts they can use to argue fault. A small shift in percentage can now completely change the outcome.
These disputes often come up in crashes like:
- rear-end collisions where the front driver stopped suddenly or is accused of brake-checking
- left-turn crashes where both drivers disagree about signal timing, speed, visibility, or right-of-way
- multi-vehicle pile-ups where several drivers may share responsibility
- lane-change crashes involving blind spots, missed signals, or disputed timing
- pedestrian crashes where crosswalk use, visibility, and driver attention are all questioned
In these cases, the facts do more than explain what happened. They can move the fault percentage just enough to change the result.
Insurance adjusters have already begun using the new framework for 2026 claims. That makes evidence, including photos, witness accounts, video footage, police reports, vehicle damage, and details about how the crash happened, especially important.

FAQs
Does the new 51% rule apply if my crash was before January 1, 2026?
No. HB 431 applies prospectively, meaning it governs causes of action that arose on or after January 1, 2026. If your crash happened before that date, Louisiana’s pre-existing pure comparative fault rule still applies to your claim, even if you file or settle in 2026 or later.
What counts as being “at fault” for a Louisiana crash?
Fault under art. 2323 refers to Louisiana, where a person’s negligence was a proximate cause of the injury. It is stated as a percentage. Courts and juries may consider speeding, following too closely, failing to yield, distracted driving, and failure to adjust for other conditions. Each party’s share is allocated within the total 100%.
If I’m found exactly 50% at fault, do I still recover?
Yes. The statute bars recovery only when the plaintiff’s fault is “equal to or greater than fifty-one percent.” A plaintiff who is found to be exactly 50% at fault remains below the cutoff and may recover 50% of their damages.
How does the 51% bar affect multi-vehicle crashes?
In multi-vehicle crashes, fault may be split among several drivers. That can make it harder to predict the plaintiff’s final percentage. Careful documentation of each driver’s actions and a clear reconstruction can matter because even a small change in fault allocation may decide whether recovery is available.
How long do I have to file the plaintiff’s personal injury claim?
Louisiana extended the prescriptive period for personal injury claims from one year to two years under Act 423 of 2024. The change applies to actions arising on or after July 1, 2024. For crashes in 2026 and later, that two-year deadline applies alongside the 51% fault bar.
Conclusion
Louisiana’s shift to a 51% bar changes the stakes in shared-fault crash claims. Under the old rule, a mostly at-fault plaintiff could still recover a small portion of damages. Under the new rule, recovery ends once the plaintiff’s fault reaches 51%.
That makes fault allocation especially important in close-call crashes. When the facts are disputed, early evidence about speed, visibility, traffic signals, right-of-way, impact points, and witness accounts can affect whether the claim remains recoverable.
