The remains of a random person? I wouldn't think so.
But this is his uncle, so he probably has some sort of "next of kin"-type allowance. It was either pay for a burial plot (lots of money), pay a monthly fee to continue storing the remains (also lots of money), or take the box of remains out of storage.
@Egil It's the unfortunate side effect of marketing rare items towards children. You have manbabies trying to do everything to keep the kids from getting it, so they can have the valuable item.
