In the most straightforward case, the statute of limitations on wrongful death, or the time period within which a wrongful death lawsuit must be filed with the appropriate court, begins to run on the date that the wrongful death occurs. There are, however, situations that have created exceptions to this general rule. For instance, if a person is severely injured due to another's negligence, but does not die from the injuries until several months, or even a few years, later, then the statute of limitations may not begin to run until the person's wrongful death actually occurs. However, some state laws may require that a personal injury lawsuit be brought on the person's behalf prior to the relevant statute of limitations, in order to preserve a potential wrongful death claim in the future. Given the possible complexity and exceptions to these statute of limitation laws, which are different in every state, it is essential to contact a knowledgeable attorney who can best advise you on these issues related to your wrongful death claim.
