Exactly that. My 'father' although I use the term VERY loosely has died and I am being very heavily leaned on to arrange something for him. And most probably pay for it as well.
I've been n/c with F for almost 30 years so how the hell anyone has got my contact details is well beyond me. At no point would I ever say OK to having any kind of dealings in connection with him. Because he was an evil bastard when me and my siblings were growing up. As soon as I could I changed my name by deed poll, one sibling moved 3000 miles away and the other sibling (who was very much the 'golden child') was so fucked up by him that they are incapable of living independently and live in a care home. 3000 miles sibling also refuses to get involved and sibling #3 wouldn't even understand what a funeral is, let alone arrange and pay for one.
So how can I tell everyone to leave me alone. As far as I am concerned F can rot in hell. I want absolutely nothing to do with F, I definitely don't want to have any part in signing anything or arranging anything. However I'm being hounded by the funeral home to arrange things and being told that if I don't then I am going to be fined and/or arrested.
