Family died in a plane crash in Utah. Their residence is in Az. Does the family need an Attorny in Utah or Az? Can siblings file a wrongful death?

This sounds like a tragic accident and I am sorry for your loss. The answer to this question is a bit complicated. There are many things to consider when hiring an attorney, such as what exactly gives rise to the claim? Was it something that happened in Arizona on a flight to Utah or was it a flight that originated in Utah with no connection to Arizona? Where do the next of kin reside? The answer to the second question depends on the first in a way. In other words, where the suit is filed may determine who can bring a wrongful death claim. While this may not be a satisfactory answer the reality is that more information will be needed to determine a good course of action. Most if not all wrongful death attorneys should be able to provide a free consultation to review the answers to the above questions. I would begin with an attorney in the same state as the person seeking answers.
