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.
In most, if not all common law jurisdictions, there was no common law right to recover civil damages for the wrongful death of a person. However, many jurisdictions have now enacted statutes to create a right to such recovery. The issue of liability will be determined by the tort law of a given state.
