Personal Injury Cases: Determining Fault in Washington State
In injury cases, determining fault is the first critical step. Insurance companies initially assess who is responsible for the accident when a claim is filed. If the case is brought to trial, a jury will be assigned the task of determining fault. In some cases, the injured party will be assigned a certain degree of fault, affecting the outcome.
Washington Operates Under a Fault-Based System
Washington State operates under a fault-based system for accident and insurance laws, which means the injured party has the option to file an injury claim with the at-fault driver’s insurance company.
What Does No Fault State Mean?
Washington is not a no-fault state for car accidents or other types of personal injury claims. States that operate under that system require drivers to file claims with their own insurance company for bodily injury after an accident, regardless of who is at fault.
Washington Is a Comparative Fault State
In addition, Washington State is a comparative fault state, which means that fault can be shared in a personal injury case. Damages are awarded based on contributory fault law, which says that you may only be awarded damages proportional to the percentage of fault contributed by the defendant and nothing for the amount of fault that you contributed.
Specifically, Washington follows the Pure Comparative Fault Rule (also called the pure comparative negligence theory), which allows the injured party to recover even if they are 99 percent at fault but where the court or adjuster will diminish the award in proportion to the degree of fault of the injured party. In other words, the recovery is reduced by the injured party’s degree of fault. For example, if damages are calculated at $1 million, but the plaintiff is 30 percent responsible for the accident, they are only entitled to recover $700,000.
Washington also follows the theory of Joint and Several Liability. This means that each defendant is liable for their own share of the monetary award unless the plaintiff is not at fault at all, in which case each defendant will share in the responsibility of all liable defendants.
