How do you find the location of a safety deposit box and life insurance policy of a deceased person?

try your state comptroller office website Safety deposit boxes and insurance policies are private issues and are not a matter of public record. An insurance provider would not release the information without authorization from the executor of the deceased estate or an order from the probate court (POA's become null and void upon the death of the grantor). About the only option is to search through the deceased's possession/paperwork for cancelled checks, bank statment's, policies, account statements, tax returns and so forth.
