Is my mum being unreasonable regarding the inheritance that may become available following my dad's death.....
My dad is unwell at the moment, and my mum has always had it in her head that he will die before she does. They separated about 20 years ago and now have new partners. When they split up they separated all of their possessions - she had one house, my father had the other, and because her house was worth less she had a cash lump sum to make up the difference. She also recieves just under half of my Dad's lucrative pension. At the moment she is renting out her house because she is living with her boyfriend.
The complication is that both of their names are still on both of their houses and they are still married (I know, ridiculous). They just never finalised it. My mother is now denying that she had a cash lump sum and said her settlement was 'unfair'. We know for a fact how much money she had, so this is untrue. She is telling my brother and I that when our Dad dies, she will inherit his money and house and we will have nothing.
Is it normal for someone who has been practicaly divorced/separated from someone for 20 years, to expect to then inherit from their ex? Dad does not want her to inherit and wants the house to go to us, but he is too frightened to challenge her (divorce) and she evades attempts to change the names on the houses so that they legally have one each.
