Kansas's rule: barred at 50%, not 51%
Under K.S.A. § 60-258a, a claimant whose own negligence is 50% or more is barred from any recovery at all. Read the other way: a claimant whose fault is less than 50% is not barred, and their damages are reduced in proportion to their own percentage of fault. This is a genuinely stricter threshold than the more common 51%-bar states — in Kansas, an exact 50-50 split between claimant and defendant results in zero recovery, not a reduced one.
The 49/50 distinction, precisely
A claimant found 49% at fault still recovers 51% of their damages under Kansas's rule, because 49% is less than 50%. A claimant found exactly 50% at fault recovers nothing at all. This single-percentage-point line, one point stricter than states like Connecticut or Illinois that use a 51% bar, is what makes Kansas meaningfully less forgiving at the exact midpoint.
Worked example
Someone with $200,000 in damages, found 30% at fault, recovers $140,000 — reduced by their own share, since 30% is less than 50%. That same person, found 50% at fault instead, recovers nothing at all, even though their share of responsibility only shifted by a modest amount past the quarter mark.
No joint and several liability
The Kansas Comparative Fault statute also abolished joint and several liability among multiple defendants. Rather than any one defendant potentially being on the hook for the full damages amount regardless of their individual share of fault, each defendant in Kansas is generally responsible only for their own proportionate share, based on the percentage of fault actually attributed to them.
Who decides the percentage
The trier of fact — typically a jury, where a case reaches trial — compares the negligence of the claimant against the negligence of the defendant or defendants. In the far more common scenario of a negotiated settlement, this same comparison is effectively worked out between the parties based on the available evidence.
Why the fight over fault stays intense near the 49/50 line
Because the practical difference between a 49% finding and a 50% finding is the difference between a substantial recovery and zero, insurers have a real, concentrated incentive to argue a claimant's fault upward toward that exact threshold. See our guide to how adjusters build a fault argument in Kansas for what that negotiation actually looks like.
