movement from the original grave to a different family plot
repatriation overseas
a court order that requires further forensic examination
Things to consider
exhumations are rare and expensive
legally a licence is required from the Home Office before any arrangements can be made
it is an offence to exhume any human remains without having the necessary permissions
an environmental health officer must be present to supervise and ensure the respect for the deceased person is maintained and that public health is protected
if the conditions of the licence cannot be met, or there are public health or decency concerns, the exhumation may not go ahead
