Traditionally, the previous occupant is exhumed and their bones deposited in the ossuary building. I imagine a modern cemetery just quietly trashes the headstone when the lease expires, and re-leases the plot at full price, as though no one had already been buried there. I'm not sure when the gravesite lease for ethical business practice expires.
