Anyway we'll be in paradise so who cares
Your executor will I can assure you. I had the misfortune to act as executor for a relative who gave substantial sums to 3 charities and one NFP organisation (think that this was also a charity). This resulted in an enormous amount of work on my part and little help from the beneficiaries.
Because they are duty bound to make the most of their finances they scrutinised everything I did and it has left me with the feeling that the charity I leave my money to will be my family.
