So background dh has two dc (ds and dd) and I have two boys.
This is what dh thinks Is fair either me or dh passes away the surviving partner gets everything. Then when the sole partner dies it will be divided between all four dc.
I am against this I have money I've inherited including a property that I don't want dh's dc to get a share of it because why should they.
I think it should be split and be given to dc in trust when the dc die.
