The DOHSA applies only to deaths caused by unseaworthy vessels or negligence. Proving negligence can be difficult, particularly because the incident occurred in foreign waters. It takes a detailed investigation to uncover evidence that proves negligence–a failure to act with proper care or caution in the circumstances. Examples of negligence under the Death on the High Seas Act may include inadequate safety inspections, not enough lifeboats for passengers and crew, failure to replace aging equipment, failure to provide proper equipment, or unsafe conditions on the vessel. Additionally, if any equipment on a vessel is not designed correctly, reasonably maintained, or does not work properly, this may render the vessel unseaworthy and thus entitle the surviving family member of a passenger or seaman who lost his or her life to compensation under the Death on the High Seas Act.
