Louisiana’s Comparative Fault Law: Changes Effective January 1, 2026

Louisiana’s January 1, 2026 amendment adds a 51% cutoff to many negligence claims: under the amended rule, fault below 51% reduces damages, while 51% or more may bar recovery. Which version governs depends on the incident date and applicable transition law. Article 2323(C) prevents reduction when the harm results partly from the injured person’s negligence and partly from an intentional tortfeasor’s fault.

What changed on January 1, 2026

Comparative fault is the process of assigning percentages of blame to everyone who caused or contributed to an injury. The updated version of Louisiana Civil Code art. 2323 keeps the percentage approach but adds a key threshold in many negligence cases: if the injured person is 51% or more at fault, recovery may be barred. Below that line (less than 51%), damages are typically reduced by the injured person’s percentage.

For the general framework beyond this 2026 change, see our Louisiana comparative fault overview.

• Percentages still matter: The factfinder assigns fault as a percentage.
• Less than 51%: Damages are reduced by the injured person’s share of fault.
• 51% or more: Recovery may be barred in many negligence cases covered by the updated rule.
• Small swings can matter: When the defense seeks an allocation of 51% or more, evidence that changes the supported fault percentage can be important.
• Jury instruction is addressed: If comparative fault is submitted to a jury, the jury must be instructed on the effect of the rule.

Before vs after: accidents before Jan 1, 2026 vs on/after

Effective date: Act No. 15 (HB 431) states the amended rule becomes effective January 1, 2026. Under Civil Code article 6, substantive laws generally apply prospectively unless the legislature provides otherwise. Which version governs depends on the incident date and applicable transition law; filing or negotiating after January 1, 2026 does not by itself make the new cutoff apply. Earlier incidents require review under the prior law; a near-date or legally complex timeline needs individual analysis.

Accident date	Rule in plain English	Why it matters
Before January 1, 2026	Comparative fault often reduced damages by the injured person’s percentage.	Fault disputes still mattered, but the “51% bar” may not apply the same way.
On or after January 1, 2026	Many negligence claims face a 51% threshold: 51%+ may bar recovery; less than 51% reduces damages.	The defense may focus more on seeking an allocation of 51% or more.
Near the effective date or legally complex timelines	The controlling rule can depend on details.	Do not assume—confirm quickly.

Three simple examples (with easy math)

These examples use $100,000 to keep the math simple and assume a negligence claim governed by the amended rule, without the Article 2323(C) intentional-tort exception. The incident date and governing law must support those assumptions. Real cases can involve disputed damages, multiple defendants, and insurance limits. This is general information, not legal advice.

Example A: injured person is 10% at fault

Total damages (example)	$100,000
Injured person’s fault	10%
Reduction	$10,000
Estimated recoverable damages	$90,000

Example B: injured person is 50% at fault

Total damages (example)	$100,000
Injured person’s fault	50%
Reduction	$50,000
Estimated recoverable damages	$50,000

Example C: injured person is 51% at fault

Total damages (example)	$100,000
Injured person’s fault	51%
Effect under post–Jan 1, 2026 rule	Recovery may be barred for many negligence claims.
Estimated recoverable damages	$0 (under the 51% bar)

What the “jury instruction” language means (plain English)

The statute includes language about juries: when comparative fault is submitted to a jury, the jury must be instructed on the effect of the rule. In plain English, that means jurors are not only asked to assign percentages—they must also be instructed on the effect of the rule under art. 2323 (as amended by Act No. 15).

• Jurors may be asked to assign fault percentages to everyone involved.
• When comparative fault is submitted to a jury, jurors must be instructed that fault below 51% to the injured person reduces damages, while 51%+ may bar recovery in many negligence cases under the updated rule.
• This can make evidence that affects fault percentages more important, because small swings can matter.

FAQs (short answers)

What is comparative fault in Louisiana?

Comparative fault assigns percentages of responsibility to people whose conduct caused or contributed to an injury. Those percentages may affect damages, but the applicable reduction rule depends on the incident date, governing law and statutory exceptions.

What changed on January 1, 2026?

For negligence claims governed by the amendment, 51% or more fault may bar recovery, while less than 51% generally reduces damages proportionately. The incident date and transition rules determine whether that version applies. Article 2323(C) prevents reduction when harm combines the injured person’s negligence with an intentional tortfeasor’s fault. See art. 2323 and Act No. 15.

Can I recover if I am 50% at fault?

Often, yes. For a negligence claim governed by the amended rule, 50% fault ordinarily reduces damages by half. Confirm the incident date and applicable law; Article 2323(C) instead prevents reduction when the harm combines the injured person’s negligence with an intentional tortfeasor’s fault. Evidence matters when the other party argues that your share should reach the 51% bar.

What if I am 51% at fault?

If the amended rule governs the incident, 51% or more fault may bar recovery on a negligence claim. Earlier incidents require review under the prior law. Article 2323(C) separately prevents reduction where harm results from both the injured person’s negligence and an intentional tortfeasor’s fault, so the percentage alone does not resolve every claim.

Does the 51% rule apply to every kind of case?

No. The claim, incident date and governing law matter. Under Article 2323(C), a claim is not reduced when harm results partly from the injured person’s negligence and partly from an intentional tortfeasor’s fault. A serious traffic violation alone does not establish an intentional tort. A lawyer can review whether this or another exception applies.

How are fault percentages decided?

Fault percentages are based on evidence about what each person did or did not do and how that contributed to the harm. Early insurance decisions can change when better evidence (video, witnesses, measurements, records) is found and preserved.

Can fault be assigned to someone who is not in the lawsuit?

Louisiana’s comparative fault statute addresses allocation among all persons who caused or contributed to the harm, including nonparties in many situations. This can matter when the defense blames an “empty chair” to raise the injured person’s percentage.

Why does the jury instruction language matter?

When comparative fault is submitted to the jury, the statute requires instructions on the rule’s effect. That explanation must match the law governing the incident and any relevant exception, rather than assume every case uses the 2026 cutoff.

What happens if my accident was before January 1, 2026?

An earlier incident requires analysis under the prior law and applicable transition rules. Act No. 15 sets January 1, 2026 as the amendment’s effective date; filing a lawsuit later does not by itself select the new rule. Have the incident timeline and any claim-specific exceptions reviewed promptly.

Should I accept an insurer’s fault percentage right away?

Be cautious. A fault percentage can be part of negotiation, not a final determination. If fault is disputed, seek legal guidance early so evidence is preserved and you can assess the proposed allocation against the facts and the law governing your incident.
