Apologies for the length, I'll try and keep it brief.
TLDR: should I tell a man who has never shown any interest in his family to piss off with his desire to chase his inheritance.
My father is the ultimate hands off dad. Several wives, several children. Only ever involved in the life of the youngest (who has now died).
I was brought up by his parents. They weren't great. Grandma mentally ill and my father subsequently didn't figure much in my life, Occasional visits and took me on holiday a couple of times. I eventually went NC with my grandparents. They split up and my grandma stayed in the house. She died 30 years ago (my grandfather predeceased her).
The house was sold and her daughter (my aunt) as far as I know took the money. She gave some to me. I doubt there would have been much as the house was mortgaged and in a state. I never questioned this as my aunt tried to maintain contact -despite the impact on her own MH - liaised with health care about her mother, tried to make sure she was OK, arranged the funeral, despite her mother being quite abusive to her. My father was nowhere to be seen. Didn't go to the funeral.
For added context my aunt also made sure her father was in a home near her when he got dementia and stayed in close contact with him. Frankly the woman was a saint and deserved any penny she got.
My aunt has since died, her estate has gone to her husband. In the meantime my father has recently been in touch. Apparently as he is now an old man he wants to make amends and is writing to all the people he has 'wronged'. This will take him a while. He is in a home overseas. Apparently comfortably off.
Anyway he now wants to know what has happened to the money from 'his mother's house'. He assumed the money was illegally taken my his sister (my aunt) and has now gone to her widower, and is determined to 'pursue this'. This is a man who didn't give a shiny shit about his mother when she was alive.
I was happy to keep some minimal contact by email on the basis that he is an old, dying man. Now I'd like to just tell him to do one. Added context, I haven't seen him for over 30 years and apart from the very, very rare birthday card barely heard from him up until a couple of years ago.
ETA: I have no idea if my grandma made a will, but I highly doubt it
YANBU: Just tell him to bugger off with his sudden interest in his family
YABU: He's entitled to his inheritance
