Wrongful Death: a claim in common law jurisdictions against a person who can be held liable for a death. The claim is brought in a civil action, usually by close relatives, as enumerated by statute. Under common law, a dead person cannot bring a suit, and this created a legal hole in which activities that resulted in a person's injury would result in civil sanction but activities that resulted in a person's death would not.
The standard of proof in the United States is typically preponderance of the evidence as opposed to clear and convincing or beyond a reasonable doubt. In Australia and the United Kingdom, it is 'on the balance of probabilities'. For this reason, it is often easier for a family to seek retribution against someone who kills a family member through tort than a criminal prosecution. It should be noted, however, that the two actions are not mutually exclusive; a person may be prosecuted criminally for causing a person's death (whether in the form of murder, manslaughter, criminally negligent homicide, or some other theory) and that person can also be sued civilly in a wrongful death action (as in the O.J. Simpson cases).
