So.... just got on this thread and will not be reading it all... just want to add my real world experience...
You NEED to tell people if you put them down as a beneficiary on any account!!!
I knew there was some money my mom left for someone and as executor I kept calling them to find out who... I was told they would NOT give me that information as it is 'confidential'....
One day when I called I forgot to tell them I was the executor and GUESS WHAT

I was the beneficiary!! They would not talk to me when I said I was the executor but were very helpful when I was the beneficiary...
And if I had not known about that account it would have gone uncollected... maybe some day in the future I would see it as state funds but who knows...
