What's the cheapest money can buy..??
A bottle of cheap Lidl whisky, some prescription pain killers and sit on the fence of a large pig pen full of hungry lawyers er sorry I meant pigs. Take tablets, drink whisky, slit wrists and as the life drains away, slump into the pen and let the hogs feast.
Beat me to it! I once employed a cleaning lady on a minesite in Tanzania who, I was warned by our nurse was suicidal. There was plenty of opportunity for a self-organised 'disappearance' because of the many deep holes on the land around us (which caused quite a few accidental and otherwise disappearences of those unwary to the danger), and she duly vanished; she had told someone that she was going to do it, though, so a search never took place.FFS. You put some thought into that.
Yup, about 5 seconds worth. Mind you as a member of the REA I get a free funeral anyway.
I offered to leave my body to science, and was sent a long form to fill in by the university concerned. It turns out that they don't want cadavers with the sort of things wrong with them which tend to kill former military types, so bugger off.Serious reply - well a bit serious - cremation followed by scattering the ashes somewhere.
You could go to the council and say there are no relatives and no estate (bear in mind that Probate and the Will are public documents and can be seen by anyone) and they will pick up the tab.
You can also leave the body to science and it will be dismantled by a medical student for fun - err - educational purposes.
