I would ask your brother (or his wife) how you can help
The danger with you helping your brother is what the future holds - would you get stuck in next of kin role for years?
This is more than helping your brother, it is about the long term
I think the problem is, if either myself or my brother don't do it, his OTHER next of kin is my uncle. Who cheated my father, my brother and I out of our half of the inheritance from our grandparents.
So if bro can't do it and I don't, if father dies and uncle is in charge, my brother will get nothing.
Bloody families.
