So I think though the 50/50 is sensible and easier, they have come to the arrangement of splitting the house into 4 plus small amounts for GC. DH does not seem to be fighting that anymore.
I like the idea of actually naming the current GC so they don't have to be associated with anyone, then adding the extra GC born after this date bit.
The adopted GC was adopted in near sight of the family so knows they are family and who his mum is, but they are not in touch. GC is an adult.
I think the DW is worried about putting his name on the will and then questions being asked 'who is this' by estranged Dds family.
Personally I think that is very unlikely! Especially is named separately with no reference to DD.
They have been to a solicitor about this and the will drawn up is so complicated and they aren't happy. It currently leaves a bit extra to any DC who have children, for them to distribute to GC. Doesn't seem clever to me, and surely has tax implications.
It was suggested one of us get the adopted GC portion, but that would then need to be given as a gift of 3 or possibly 6k, who knows if they are in a position to do that legally at the time. Seems better to have it all in the will.
I think what confused it further is, that the solicitor advised to just divide into 4, leave equally. GCs get nothing while DCs are living. If they die, that portion goes to GCs. Hence the having to specify one of them by name... ergh messy
