[QUOTE=Spectre of Pithecanthropus]
From what I’ve seen, in the U.S. permanent graves, or crypts, are the rule. In my home town of Los Angeles, of all places, there is a cemetery that was founded in 1877 and, I’m sure, contains the graves of some who were born before 1800. It’s a little sad to think of a mausoleum or grave that’s so old there aren’t any descendants anymore to pay their respects, or that said descendants have forgotten.
Sometimes graves do have to be moved, but they are still preserved in the new location. There are a few early cemeteries in L.A. that were moved to new sites to make way for development.

A good place to start is the quintessential treatise on burial law, The Law of Cadavers by Percival Jackson (1936). Mr. Jackson gives us the basic rule of U.S. burial law:
The cumulative effect of primitive fears of the spirit, apprehensions or hopes of resurrection, modern concepts of morals and habits of devotion, respect, and sentiment–all these presently produce an undeniable recognition of the rights of the dead and the living to have respected the peaceful and unviolated sanctity of the grave. It may be generally said that once a person is buried, the law, having a proper respect for the dead, a just regard for the sensibilities of the living, and a care for the due preservation of the public health, jealously guards the grave against ruthless or unjustifiable intrusion.
Essentially, once you’re in the ground, anybody who wants to haul you back out, move you, or move your tombstone needs official approval.
When you buy a lot in a cemetery, you generally get the right to choose whose body goes in there. If someone gets put in your lot by mistake, you can have them moved. Once the body goes in, it’s pretty hard for somebody else to move it. But it does happen. Cemeteries are subject to condemnation. Natural disasters sometimes disinter graves. An inactive cemetery can become a nuisance subject to abatement. Under some circumstances, a person can purchase an abandoned cemetery and get government permission to move the graves to another cemetery or even remove the tombstones and build over it (although this is pretty rare). Even if you were buried in your backyard, the property could be condemned, or your heirs could sell it, and the new owner could try to develop the land. The dead can’t defend themselves–the fate of their remains is in the hands of the living.
The preceding applies to the U.S., you understand–practices elsewhere vary, as we’ll see in a moment.
