The following rules apply when the son whose status is doubtful and the brother who married the widow come to divide the estate of the father of the family. The brother who married the widow is definitely an heir. In this instance as well, there is a question concerning the rights of the son whose status is doubtful. If he is the son of the deceased brother, he receives half; if he is the son of the brother who married the widow, he does not receive anything. Therefore, the estate should be given to the brother and the son whose status is doubtful should be overlooked. The following principles apply with regard to the inheritance of the grandfather's estate if the brother who married the widow left two sons whose lineage is definite and died. The son whose status is doubtful claims: "I am the son of the deceased brother. Hence, I should receive half and you two should receive half." The two sons say: "You are our brother and the son of the brother who married the widow. Hence, you deserve only one third of the estate of our grandfather." ? The two sons receive the half that the son whose status is doubtful acknowledges as belonging to them. The third that they acknowledge as belonging to him is given to him, and the remaining sixth is divided equally: he receives half of it and they receive half of it. ? If the son whose status is doubtful dies, the brother who married the widow may claim: "Perhaps he is my son and I have the right to inherit his estate." His father may say: "Perhaps he is the son of my deceased son and I have the right to inherit his estate." In such a situation, they should divide the estate equally. (If the son who married the widow died, the son whose status is doubtful may claim: "He is my father and I have the right to inherit his estate." His father may say: "Perhaps you are the son of my other son and this is your father's brother. Thus, I have the right to inherit his estate." In such a situation, they should divide the estate equally.)
