What is the younger brother's share of the inheritance, knowing that he previously received 10,0 pounds, and the house was valued at 90,0 pounds?

If the father gifted an apartment to his son, and the son took possession of it during the father's lifetime, it becomes the son's private property, and the other heirs do not share in it. As for the remaining apartments, they are part of the inheritance and are to be divided among the heirs according to each one's share. The younger brother has the right to demand compensation for his share of the apartments' value. It is advisable to reach a mutual agreement and make concessions to preserve affection.
