Okay, so I'll preface by saying I don't think IABU, however I want a reality check from a non-emotive standpoint. I am also no-one of the people mentioned, but am aware of the situation.
Grandparent A has passed away. They left money to their biological children and biological grandchildren. This includes property and cash, the total of which is just shy of £1mil.
One of A's children - Bob - has a child from way back, and two step children.
The grandchild is unaware of the full extent of the will. They were close with their grandparent, however were not kept in the loop regarding the money side of things.
Bob is fully aware of the detail of his parent's will and the total of the cash assets. Despite Bob's parent passing away well over a year ago, he has not informed his first child who is now an adult in their mid-thirties.
Previously, Bob has withheld money left specifically to his first child when his other parent passed away. This was eventually revealed years after the death when Bob's sibling mentioned it in passing to the child, believing that the money had been passed on. The child was a young adult at the time, and didn't feel able to confront Bob, so the whole thing was brushed under the carpet.
So - here is my AIBU. Should I tell the child that Grandparent included them in the will. Bob and their child's relationship has massively improved in recent years after being not very present in each others lives when the child was younger, but this would put a massive cat amongst the pigeons.
Or should I keep my beak out, I am unrelated to the family and it is not any of my business?
I am more tempted by the first option and am pretty angry about Bob's handling of the situation!
