Proof of life. This actually happened to the uncle of someone I work with. He's Indian, and his uncle served in the Army. As such, he gets a pension. However, ever year, to continue receiving his pension, he has to submit paperwork proving that he's still living.
While that's one thing, last year he moved to a different area of India. At the beginning of this year, he goes to the proper office and submits his paperwork for this year. But since he moved, was asked to produce paperwork proving he was alive the previous years.
Basically, "prove to me you were alive last year." Of course, the fact that he was standing there ... you would seem to think it was obvious.
I guess to the Indian government it was not.
He had to jump through hoops to get the proper paperwork (hard for a dead person, frankly), but he finally got it all ironed out.
