"If a man dies and leaves behind a wife and grandchildren (descendants of his children), the wife receives one-eighth of the inheritance, and the remainder goes to the grandchildren. If a woman dies and leaves behind her husband and grandchildren, the husband receives one-fourth of the inheritance, and the remainder goes to the grandchildren. This division is because the husband and wife are not considered primary heirs by blood; rather, they inherit through marital relation, not through lineage. Therefore, the grandchildren take the position of the direct children when there are no surviving children or parents of the deceased."
