A cohen must not defile himself for the deceased, i.e. come within four amot (approximately six feet – 1.85 meters) of the place where the deceased is located, or enter the house in which the deceased is located. If the deceased is one of the cohen's seven close relatives (father, mother, son, daughter, brother sister, and wife), the cohen is permitted and commanded to defile himself. A cohen defiles himself only if the deceased's body is whole; if part of the body is missing, a cohen is forbidden to defile himself, even if the missing part is laid by the side of the body or stitched and connected to the body. If an autopsy has been performed on the deceased, relatives of the deceased who are cohens do not defile themselves. A cohen is permitted to accompany his relative to the grave if there are no other graves within four amot on the way.
