Do you think you might still have life insurance, but you can’t find the policy? Do you think a deceased relative had a policy that no one has ever claimed? If so, you might be able to find it on the State of Michigan’s unclaimed property website: https://unclaimedproperty.michigan.gov
If you don’t know the name of the insurance company, you can try using the Life Insurance Policy Locator, a national database that is run by the state insurance regulators at: https://eapps.naic.org/life-policy-locator/#/welcome
Once a request is made to locate a policy, the National Association of Insurance Commissioners will ask all of its participating companies to search their records for a match.
If your deceased loved one was in the military in the pre-Vietnam era or was a service-disabled veteran, you can also search at: https://insurance.va.gov/unclaimedfunds
