How does South Carolina's fault system affect my Duncan car accident claim?
South Carolina follows a modified comparative fault system under SC Code Ann. § 15-38-15. Unlike the contributory negligence rule used in a small number of states — where being even slightly at fault can bar all recovery — South Carolina allows injured people to recover as long as they are 51% or less responsible for the crash. Your recovery is reduced proportionally by your percentage of fault. This means handling fault carefully still matters in a Duncan accident case — reducing your assigned fault percentage directly increases your potential recovery.
