My uncle on the other hand is greedy and wants the most money he can get from his share of my aunts estate.
He has no money and will rely on the sale of her house,
He is not greedy to expect half his sisters Inheritance,
Actually he is being generous to his Brother he is not trying to have a one sided relationship with his brother far from it he is trying his best to facilitate him,
I cannot understand how he can be called greedy, to me greed is expecting to get more than you are entitled to,
If fact he has offered to take less from your father if he wishes to move into his late sisters house,
You appear to be suggesting if your father takes over some of his late sisters estate his brother should be grateful to get 50% of what is left when sold, Can you see how that thinking is not fair on your uncle,
The best way to make sure there is no bad feelings when all this is sorted is for your father to insist his brother gets at least 50% or a little more of his sisters Inheritance for facilitate his brother wishes,
Just like the way his brother your uncle is going at least 50% if not more to facilitate your fathers wishes,
