Is there a way to double check to see if someone deceased had life insurance?

Findyourpolicy.com provides a A free Central Database to help Consumers protect their beneficiaries from losing their life insurance inheritance. If the deceased person had a life isnurance policy, they may have registered it with this service so you could find out. Also, you may want to check with their life insurance agent, or review their canceled checks, or their checkbook, to find out if they were paying life insurance premiums, and to what insurer.
