> "Over there" is one of those countries where hundreds of people register their adress with the government at the house of an unsuspecting widow?

In e.g. Germany that requires a signed statement from the landlord, and the ability to receive mail at that address. If you can't receive mail at your own address, it'd be noticed and reported within at most 5 years. I actually believe it'd be the national health insurance that'd be the first to notice & report you missing, as having health insurance is mandatory (even if you continue paying them, they'd notice it once they can't send you a replacement card).
