Do the money and real estate that the father bought in his name, with the money of his sick son for whom he was a guardian, enter into his estate, and is the mother's share calculated from it, or does the mother only inherit from the apartment that the father bought with his own money?

Your father's estate (money and real estate) is to be divided among his heirs: his mother (one-sixth), his wife (one-eighth), and his children (the remainder, with the male receiving the equivalent of the share of two females). The funds that belonged to your brother and were managed by your father as an agent are the property of your brother. Your father is permitted to take from them only for his own needs, not to purchase real estate or land, unless with the intention of preserving his son's money or entering into a partnership with him. If your father seized his brother's money and bought things for himself, then what he bought must be returned to his brother. If your father exerted effort and invested the money, then a profit share, such as one-third or one-half, should be estimated for him. This share will then transfer to his heirs, and the remainder will go to your brother.
