I work in the insurance industry and depending on the state that you are in (actually very few do not) the policies will pay for suicide if the policy has been in place for longer than 2 years.
Another angle to take is that the policy will pay unless the suicide was planned prior to taking the exam or taking the policy out. The burden of proof is on the insurance company to prove that the person was already planning, pre-meditating this suicide before even taking the policy out=very tough to do unless there is a written plan dated before the policy was active.
I also unfortunatly am familiar with these clauses as this is what took my fatehrs life as well. Any help that I might be able to pass along I would be glad to share.
It is important to concentrate on the emotional side of things but even if no one wants to bring it up the $$ side of things are just as heavily on your friends mind right now (and should be) as well. Someone needs to work on rounding up policies, 401Ks, etc...find out how long a death certificate with take to get (might be longer in case of suicide as it is considered a "crime" technically) might be a short time. You will need death certificates for any insurance claims, etc.
Also another place to look is with this mans group health insurance policy there is often a low cost rider that can be bought with a set $$ amount of life insurance up to 3,4,5X his salary paid thru the group health company and that would have no suicide out clause either.
Hope this helps, I will have more later I am sure this is the stuff that comes to mind right away going back thru my memory of what I did and learned with my dads case....
