Many thanks Al, that is pretty clear and I feared it might come to this.
The daughter occupying the house does not have the funds to buy out her sister. She lived with my late sister for over 13 years with her partner and both her children were born into the house. She is claiming it is her family home and that her children will be emotionally scarred if required to move (my sister passed away months ago).
However, my sister`s will is that her estate is divided equally. Would her claims of moving from the family home and the emotional effects on her family carry any weight if it goes to Court?
