You can only watch this if you are in the UK, I assume. Skip to 10 minutes into the video to get to the start of this part about Russell Davison talking about keeping the body of his wife home for six days before the funeral (10:00 - 20:23):
I am talking about bringing my husband's body home before the funeral. He died in a car accident and had to have an autopsy. We organised the funeral ourselves and buried him on private land.
Basically this short video is showing people how it is not necessary to hand over to funeral directors unless you want to. It is possible to keep the body at home until the funeral or to bring it home once it is released by the coroner, if the death is due to an accident or other unexpected circumstance.
