Claims and Injuries
Personal Injury and Comparative Fault in Mississippi
How Mississippi's pure comparative fault rule divides damages, what a plaintiff must prove in a negligence case, and the three-year filing deadline.

Mississippi is one of the last states to have adopted comparative negligence, and it adopted the purest version of it. The rule has been in the code for more than a century, and it decides how much money changes hands in most injury cases that go to a verdict. Understanding it is the difference between reading a verdict as a win and reading it as a fraction.
What a plaintiff must prove
A negligence claim in Mississippi has four parts. The defendant owed a duty of reasonable care. The defendant breached that duty. The breach caused the injury. The injury produced damages that the law can measure. All four must be proved by a preponderance of the evidence, which means more likely than not.
Duty is usually straightforward. A driver owes other road users a duty to drive with reasonable care; a landowner owes a duty to keep the premises reasonably safe for the people invited onto them. Breach is where the facts live: speed, distraction, a warning that was never given, a floor that was never repaired. Causation is the hardest element, because a plaintiff must show both that the defendant's conduct was a cause in fact of the harm and that the harm was a foreseeable consequence of it.
The comparative fault rule
Mississippi Code section 11-7-15 provides that a claimant's own contributory negligence does not bar recovery, but that damages are reduced by the jury in proportion to the negligence attributable to the claimant. Mississippi applies the pure form of this rule: there is no threshold of fault above which a claimant recovers nothing. A claimant found ninety percent at fault recovers ten percent of the damages.
The statute has been on the books since 1910, and the Mississippi Legislature has not replaced it with a modified rule of the kind many other states use. The practical effect is that a defendant's best argument in many cases is not that the plaintiff was careless, but that the plaintiff was more careless than the defendant, because that argument reduces the award even when it does not defeat the claim.
How the jury applies it
The verdict form usually asks the jury to assign a percentage of fault to each party, totalling one hundred percent, and to state the total damages before any reduction. The judge then applies the percentages. In cases with several defendants, the allocation becomes more complicated, and Mississippi's rules on joint and several liability determine how much of the total any one defendant can be made to pay. A defendant who is only slightly at fault may still be ordered to satisfy a larger share of the judgment if the rules of joint liability apply and the other defendants cannot pay.
Damages: what can be recovered
Mississippi divides damages into economic and non-economic categories. Economic damages include medical bills, lost wages, lost earning capacity and out-of-pocket costs. Non-economic damages cover pain and suffering, disfigurement, mental anguish and loss of enjoyment of life. Mississippi law places a cap on the non-economic portion of damages in certain categories of case, and punitive damages are governed by a separate statute that requires clear and convincing proof of a higher degree of culpability. Those limits are why a case with a serious injury is often argued as much about the category of damage as about liability.
The three-year period and the discovery rule
The general civil limitation period in Mississippi is three years under Mississippi Code section 15-1-49. The clock ordinarily starts when the cause of action accrues, which for an injury is the date of the injury. Subsection two of the same statute adds a discovery rule for latent injury or disease: where the injury is not apparent, the claim does not accrue until the plaintiff discovers it or should have discovered it with reasonable diligence.
That rule helps a claimant whose harm appeared years later, but it is not a general extension. Once a claimant knows or ought to know, the three years run, and a defendant will argue that the date of knowledge came earlier than the plaintiff admits. Shorter periods apply to specific claims, and claims against a government body run on one year with a ninety-day notice requirement.
Preserving the evidence
An injury claim is built on records. Medical treatment creates the documentation of harm; photographs and witness names preserve the scene; a prompt report creates a contemporaneous record that is difficult to contradict later. Delay damages all of these. Memories fade, cameras are overwritten and witnesses move, and a claimant who waits a year before gathering the basics starts the case at a disadvantage.
Insurance and the claim behind the claim
Most injury claims are paid by an insurer, not by the person at fault. That makes the insurance policy central: what it covers, what it excludes, and whether the claimant has uninsured motorist coverage to fall back on when the at-fault driver has none. When an insurer denies coverage it should provide, the dispute can grow into a separate claim for bad faith, which is treated in Insurance Coverage Disputes and Bad Faith.
Where the claim goes next
If the claim is not resolved by negotiation or mediation, it becomes a lawsuit and follows the route described in How a Civil Case Moves Through Mississippi Courts. Claims involving vehicles have their own evidence and coverage questions, covered in Car and Truck Accident Claims in Mississippi, and the wider set of claim types is indexed in Mississippi Civil Claims and Practice Areas.
