Wrongful death claims are brought against a defendant who has caused someone's death, either through negligence or as a result of some intentional action. Wrongful death claims allow the estate and/or those close to a deceased person to file a lawsuit against the party who is legally liable for the death. Though each state's wrongful death laws vary, these kinds of lawsuits are usually filed by a representative of the deceased person's estate, often on behalf of surviving family members affected by the death.
