Due to the sensitive nature of this question I have name changed. It's not an aibu but I would like others opinions and perspectives on this.
Just to set the scene and avoid drip feeding...
My father left my mother for another woman when I was 16 and married her when I was 18. OW had 2 children and my dad had me and my db. My father has or will have 2 pensions, half the equity in a 4 bedroom house in the south, a life insurance pay out, a car and some other minor assets.
My father is sadly dying and probably only has months to live. He told me recently that his will states everything is being left to his wife and when she dies will be split 4 ways between us 4 children.
I expected that he would leave everything to his wife tbh, the only thing I thought he might leave us was the payout from one of his pensions as it was a career he had while we were children and well before he met his wife. Anyway I'm not upset either way and don't actually expect to get anything when his wife dies either as it will likely be spent on care or she might change the will in favour of her own children.
I happened to mention this to my mum who is absolutely furious for us and said that's he's disinherited us and it's disgusting etc etc. (We're in Scotland and my dad is in England which might explain the difference in attitudes towards wills).
So my question is do I pre warn my brother incase he has the same attitude as my mum - I don't want there to be any scenes at a later date? Also is my mum being unreasonable? Are her feelings towards my dad clouding her judgement? She thinks he's showing his children a complete disregard.
