A relative has left all his estate to his grandchildren, split equally between them (in trust). He has a lot of them, also wealthy, it's c. £150k each
This has caused various frictions. E.g. one of his children has 5 children, another has none, so it hasn't been split equally between his DC iyswim.
Similarly, GC are still being born, so the childless son, may yet have children and the existing GC may end up with siblings who don't inherit.
As the adult children (parents of the GC), would you do anything to try and even this up? Is that even possible, given those who have inherited are mostly minors and the money has been left to the GC, who could decide that some of it is to be given to future siblings?
Among your own DC, how would you manage a situation where one DC had a big inheritance and another didn't?
