Is it permissible to bury two men in one grave?

Question : And a dead person is not to be buried in a place where a dead person is already buried until the first one has decomposed, and in this matter, one should refer to those with expertise in that land.

Answer : This is correct. A dead person is not to be buried on top of another dead person. This is because when a person is buried, that place becomes his exclusive domain. Just as no one resides in another person's house in this world without his consent, so no one is to be buried on top of another. However, if there is a pressing need, it is permissible to bury two men in one grave.
