The less common modified comparative threshold
Among the roughly 33 US states that use some form of modified comparative negligence, a smaller group uses the stricter 50% threshold — recovery is barred once the claimant's fault simply equals the defendant's, not only when it exceeds it. A larger group of 21 states uses a more forgiving 51% version instead.
The 12 states using a 50% bar
Kansas's peer group under this stricter threshold is: Arkansas, Colorado, Georgia, Idaho, Kansas, Maine, Nebraska, North Dakota, South Carolina, Tennessee, Utah, and West Virginia.
A group spanning several regions
This list isn't confined to one part of the country — it includes Great Plains states like Kansas, Nebraska, and North Dakota, Mountain West states like Colorado, Idaho, and Utah, and Southeastern states like Georgia and South Carolina. The 50% bar isn't a strict regional pattern so much as a shared legislative choice made independently across a genuinely varied set of states.
Shared threshold, separate statutes
All 12 states share the same core threshold — fault reaching 50% bars recovery — but each codifies this under its own statute, with its own precise wording and its own body of case law. Kansas's version, K.S.A. § 60-258a, also pairs the 50% bar with the Kansas Comparative Fault statute's abolition of joint and several liability — a combination not every state in this group shares in exactly the same form.
Why this matters in a disputed claim
Because all 12 of these states bar recovery at an even 50-50 split, a disputed fault percentage that lands right at the midpoint results in zero recovery here — a real practical difference from the 21 states using the more forgiving 51% bar.
