Wills and leaving to grandchildren

I would leave it as it is. Give your gc money and/gifts now whilst your alive. Set up savings accounts if you like.
But dont cause any emotional misunderstandings after your death.
Well, that's what I'm doing.

Please stick with your original will. Who knows what needs your elder children may have in the future? Legacies can create awful upset and to 'favour' one over the other two would not be fair. You could always leave a small legacy to the grandchildren directly.

Would it be easier to leave a set sum to be divided between all your grandchildren on the event of your death and to be kept in accounts which can't be accessed till they are 18? That way more money isn't left to your youngest son and you want to avoid any ill feeling if at all possible.

I wouldn’t ,I would split the youngest ones inheritance and give some to the GCs. I don’t see why the other ACs should ‘fund’ your youngests children.

You could leave a percentage of your estate to each grandchild. After which the balance can be divided.
