My family has a small piece of land they use as a family cemetery down a dirt road out in the country. A number of years ago a hog farm purchased the adjacent property and now claims that the family has no right to the burial site. They have even dug up one grave recently and just left the vault and it's contents sitting out in the open for all to see. They come to family funerals and shout at the grieving parties about how the land doesn't belong to them and that they should leave.
Can they legally dig up existing graves, some have been there more than a hundred years. Do they have a right to disrupt our funerals?
