How long does a body have to be dead before it's no longer grave-robbing and now archeology?

Question

I think history and especially archeology is a very interesting field, but I am not necessarily talking about ancient Egypt. I think that someone buried in the 1800's would be interesting to look upon, to see what they wore, their jewelry. How could you get a better account of life in the nineteenth century than that?

Answer 1

I believe I heard somewhere that a grave is bought for 100 years after the person died, and then, if necessary, it can be destroyed or the plot can be reused.

Answer 2

Right after the person assigns his or her body to science after they are dead.

Answer 3

Maybe you could volunteer to be an embalmer's assistant...

Answer 4

Well, a lot would depend on the purpose the work is being done.  Sponsored by a university?  Doing it to satisfy your own curiosity?  It would need to follow proper protocol, otherwise it is graverobbing and unethical.
