A wrongful death suit in civil court is the appropriate response if negligent behavior caused the accident and injuries sustained in the accident led to your husband’s death. A loved one needn’t die immediately for you to pursue a wrongful death case. However, the evidence must show that the accident caused the death. If a doctor treats someone for heart disease, for example, and he dies of a heart attack after an accident that caused severe head trauma, an insurance company might argue that the heart attack was unrelated and the death did not stem from their insured’s negligence.
