If you dont know your own clients life insurance history, then americo or other carriers arent a good fit for you. You would have all sorts of problems if you wrote fully underwritten companys.
It would be hard to know the client's life insurance history if you had just met them and they were unable to tell you who they had applied with in the past..
As for fully underwritten, I have always just filled in the question based on the way the client answers the question concerning other insurance and haven't had any problem.. However most of the apps, even fully underwritten, just ask "Does the proposed Insured have any other coverage in force?" .. They don't ask about other coverage applied for, disposition of the application, etc.
