The stricter, smaller modified group
Among US states using modified comparative negligence, a smaller group uses the stricter 50% threshold — recovery is barred once a plaintiff's fault merely equals the defendant's, not only once it exceeds that level. A larger group of states uses the more forgiving 51% bar instead.
The states using a 50% bar
Tennessee's peer group under this stricter threshold generally includes: Arkansas, Colorado, Georgia, Idaho, Kansas, Maine, Nebraska, North Dakota, Tennessee, Utah, and West Virginia.
A genuine contrast right next door
Tennessee's neighbor North Carolina doesn't share this rule at all. North Carolina still follows pure contributory negligence, one of only five such jurisdictions nationally, barring recovery entirely for any plaintiff fault, even 1%. Cross that state line, and the exact same accident can produce a dramatically different outcome depending on which side the plaintiff's fault falls.
A genuinely distinctive origin within this shared group
Here's what sets Tennessee apart from much of this list. While most comparative fault states, including most of Tennessee's own 50%-bar peers, adopted their rule through legislation, Tennessee is one of only 11 states nationally to adopt comparative fault judicially — through the state Supreme Court's own 1992 decision in McIntyre v. Balentine, rather than an act of the legislature.
Why this matters in a disputed claim
Because Tennessee and its peers in this group bar recovery at the midpoint itself, a disputed fault percentage landing right at an even split carries real consequences — in a 51%-bar state, that same split would still allow a reduced recovery.
