A grandparent has died and their will leaves everything to their grandchildren.
The grandchildren will receive unequal amounts as the estate is divided proportionally e.g. Divided into quarters. So a grandchild without siblings will get a quarter and grandchildren with siblings will share a quarter with their siblings.
The grandchildren are named individually- the named grandchildren are all biological grandchildren.
However one of the deceased’s children has two adopted children with their second wife. One of the adopted grandchildren was initially a step-child and the other grandchild was adopted from abroad.
The adopted grandchildren were not mentioned in the will.
He is pressuring his biological daughter to share with her adopted half-siblings. She refuses. He has now appealed to his nephew and nieces and again they are refusing.
The adopted children are still children.
One of the biological grandchildren is 16 (not the daughter of the son who is annoyed) but the others are all adults.
Can the son challenge the will on behalf of the adopted children who were adopted before the will was made?
In England. Estate is roughly 3 million pounds with the house included.
