The more common modified comparative threshold
Among the US states that use some form of modified comparative negligence, a majority use the more forgiving 51% threshold — recovery is barred only once the claimant's fault actually exceeds the defendant's. A smaller group of about 11 states uses a stricter 50% version instead.
The 21 states using a 51% bar
Wisconsin's peer group under this more common threshold is: Connecticut, Delaware, Florida, Hawaii, Illinois, Indiana, Iowa, Louisiana (for accidents from 2026 onward), Massachusetts, Michigan, Minnesota, Montana, Nevada, New Hampshire, New Jersey, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Texas, Vermont, West Virginia, Wisconsin, and Wyoming.
A genuinely distinctive comparison method within this shared group
Sharing the same 51% recovery threshold with these 20 other states doesn't mean Wisconsin compares fault the same way they do. Many 51%-bar states compare a plaintiff's fault against the combined total of every defendant together. Wisconsin instead runs that comparison separately against each individual defendant — a genuinely distinctive structural choice within this group that can produce real differences in multi-defendant cases.
A cleaner joint and several liability threshold
Wisconsin uses the same 51% figure for its joint and several liability rule as it does for the plaintiff's own recovery bar — a cleaner, single-threshold structure compared to some other states in this group, where the joint and several liability figure sits at a separate, sometimes lower percentage.
Why this matters in a disputed claim
Because Wisconsin's per-defendant comparison can produce different outcomes against different defendants within the same case, a claim that would resolve simply in a combined-total 51%-bar state can genuinely play out differently in Wisconsin.
