California’s “comparative fault” law lets people recover damages in a personal injury case even when they are partially to blame for an accident or injury.
California’s “comparative fault” law is sometimes referred to as “comparative negligence” or “shared fault.” Unlike the shared fault laws of some states, a plaintiff who is more than 50% responsible for an injury is still allowed to recover.
The jury will simply apportion the fault. The plaintiff can then recover from the defendant the percentage of his or her damages for which the defendant is responsible.
