An independent executor so your friend or family member isn’t burdened with cleaning up after you while they are still hurt.
I don’t know about that. It’ll depend on your circumstances but it’s asking a lot of a friend? My partner is getting everything and he is my executor because all the decisions should be his and because he knows where everything is. I don’t really like the idea of someone else poking through my stuff, either. Or putting him through someone else poking through our stuff.
