I'm one of 7 siblings, father is deceased.
My mother (narcissist) has fallen out with each of us at different times over the years.
My youngest sibling 40 (married, works and has a 2 year old) never left home. Her and her DH/DS live with mother.
It's understood and known that she will inherit the house. It's in the will (I've not seen will)
However, my mother purposely doesn't lodge her pension into her bank, she collects it in cash and keeps it at home. She has a separate pension paid into her bank.
My sister pays all the bills.
The reason she is keeping cash is because she doesn't want everyone to know how much she has and also so it won't be shared among us, her children.
There is no point telling her the dangers of keeping cash as she will hasn't admitted she does this.
My question, when she dies how can we prove there was a pile of cash?
