There are two types of modified comparative fault systems: "50% bar" and "51% bar."
Under a 50% bar system, if the court finds an individual to be 50% or more at fault for an accident, they cannot recover damages. They can recover damages if they are less than 50% at fault.
Under a 51% bar system, the threshold for recovering damages is a bit higher. If the court finds an individual to be 51% or more at fault for an accident, they cannot recover damages. They can recover damages if they are less than 51% at fault.
Under either system, the court will reduce the amount a claimant can recover by their percentage of fault. The court or a jury determines the percentage of responsibility based on the evidence presented.
