What would you do? Do you think this is fair.

Our will is split equally between our children only, on the assumption that in due course it will reach the grandchildren
I assume noone asked a daughter to have multiple children and it could be argued that the one-child families are being more socially responsible by having a smaller family.

Someone in my wider family has tried to manipulate their parents into favouring them because they have three children It’s caused a lot of distress among the siblings with fewer children, they feel less valued. And what happens should another grandchild arrive on the scene after your demise? They won’t get anything at all.

Presumably your daughters might still have more children. Personally I would split the estate equally between the three daughters and leave them to pass on whatever they wish to their children - if anything. That is fair.

I would leave the grandchildren the same amount each eg a thousand pounds, and split the residue equally between the daughters

Perhaps you could do as my mother did and leave each of your grandchildren a specific amount and the balance of your estate split equally between your daughters.

Personally I’d leave most of it to adult daughters, say 2/3, split equally, and would then divide the rest equally between the granddaughters.

The adult dds can always pass on some of their legacy to their children if they want to - that’s what’s generally happened in this family - the younger ones’ need is often greater.

I wouldn’t name actual sums - just percentages, since it may not be known exactly how much will be left if there’s IHT or anything else to pay.
