Four systems, and Kentucky uses the most forgiving one
American fault law splits into four real categories: pure comparative negligence, modified comparative negligence with a 50% bar, modified comparative negligence with a 51% bar, and pure contributory negligence. Kentucky uses pure comparative negligence under KRS § 411.182 — the most claimant-friendly of the four.
The defining feature: no threshold, ever
In a modified comparative negligence state, a specific fault percentage — 50% in some states, 51% in others — completely eliminates the claim once the claimant's fault crosses it. Kentucky has no such line anywhere on the spectrum. Fault always reduces the recovery proportionally and never bars it entirely, whether a claimant is 10% at fault or 95% at fault.
A genuinely small group of states
Pure comparative negligence is a minority approach nationally — roughly 13 states use it, compared to about 33 states using some version of modified comparative negligence. Kentucky's peer group under this approach includes states like Alaska, Arizona, California, Florida for most claims, Louisiana, Mississippi, Missouri, New Mexico, New York, Rhode Island, South Dakota, and Washington.
Contributory negligence: the opposite extreme
At the far other end of the spectrum sit the five contributory negligence jurisdictions — Alabama, Maryland, North Carolina, Virginia, and the District of Columbia — where any fault at all, even 1%, bars recovery entirely. Kentucky's rule produces the exact opposite outcome on the same facts: that same 1% at-fault claimant in Kentucky would still recover 99% of their damages.
What this means in practice
Because there's no fault threshold to clear in Kentucky, the strategic fight over a claimant's exact fault percentage looks different than it does in a modified comparative state. See our guide to how fault still matters in Kentucky without a bar for what that difference actually looks like in a real negotiation.
