Two versions of "modified," and Arkansas uses the stricter one
Among the roughly 33 US states that use some form of modified comparative negligence, there are genuinely two different thresholds in use. Twelve states, including Arkansas, bar recovery once the claimant's fault reaches 50% — equal to the defendant's. The other, larger group of around 21 states instead uses a 51% threshold, barring recovery only once the claimant's fault actually exceeds the defendant's, which means a claimant exactly 50% at fault can still recover there.
The twelve 50%-bar states
Arkansas's peer group under this stricter threshold is: Arkansas, Colorado, Georgia, Idaho, Kansas, Maine, Nebraska, North Dakota, South Carolina, Tennessee, Utah, and West Virginia.
Shared outcome, separate statutes
All twelve states share the same core result — fault equal to or exceeding 50% bars recovery entirely — but each codifies this under its own statute, with its own precise wording and its own body of case law interpreting it. Arkansas's version lives in Ark. Code Ann. § 16-64-122, which frames the rule as barring recovery when the claimant's fault is "equal to or greater than" the defendant's — language worth reading closely, since it's this specific phrasing that puts the bar at 50% rather than 51%.
Why the one-point difference is a genuinely big deal
It's worth being direct about what separates a 50%-bar state from a 51%-bar state in practice: a claimant found exactly 50% at fault recovers a meaningful, reduced amount in a 51%-bar state, but recovers absolutely nothing under Arkansas's rule and the rules of its eleven peer states. Given how often real-world fault disputes land close to an even split, this single-point difference in where the line is actually drawn has real, practical consequences for a genuinely large number of claims.
