We just had a question about how people are declared dead when they disappear without a trace. That got me thinking about the reverse situation:
Someone leaves behind a power of attorney and says "I'm leaving to go be with [secretive cult], don't try to find me." They're receiving some sort of lifetime payment which is going into a joint account. Nothing is ever heard from them again.
From the answers to the other question it seems impossible for them to be declared dead, do the payments continue forever?
