If one of the sons of a grandfather has died leaving behind children, will these grandchildren be able to inherit from the grandfather on his death while his other children are alive?
No, unless the grand father makes a will to give them whatever he wants to give them.
Inheritance goes to the direct children who are alive when the grandfather passed away and in the existence of direct children, no inheritance to grandchildren but with a will.
f the grandfather when he passed away had no living children but only grandchildren then all of them get the right is inheritance.
Wassalam.
