1but with regard to the halakha it does not indicate anything?
2But isn’t it taught in the mishna (157a): A house collapsed on a son and upon his father, or upon a certain person and upon those from whom he stands to inherit, and it is unknown who died first. If the son bore the responsibility to pay the marriage contract of his wife and to pay a creditor, and the son had no money with which to pay them except that which he might inherit from his father, and the father’s heirs say: The son died first and afterward the father died, and therefore the son did not inherit property from his father, and the creditor says: The father died first and afterward the son died, there is a dispute as to the halakha . The son therefore inherited his father’s property, and his creditor has a lien upon the property, enabling him to collect payment from the property even after the son’s death.
3What, is it not correct to explain that the father’s heirs are the son’s sons, and the term: Those from whom he stands to inherit, is referring to the deceased son’s brothers? And if it enters your mind to maintain that the grandson cannot say: I come to repossess the property on the basis of the right of my father’s father to the property, as when it is written in the verse in Psalms: “In the place of your fathers shall be your sons,” this is written as a blessing, then the mishna is difficult. According to this understanding, grandsons inherit from their grandfather only through their father. If so, even if the son died first and afterward the father died, what of it? Let the creditor say to the son’s sons: It is their father’s inheritance that I am taking, as the grandsons inherit from their grandfather only through their father.
4The Gemara rejects this explanation: No, the father’s heirs are the deceased son’s brothers, who certainly inherit from their father directly, and the term: Those from whom he stands to inherit, is referring to the deceased son’s father’s brothers. Therefore, one cannot derive from the mishna that a grandson inherits from his grandfather directly.
5§ The Sages raised a dilemma before Rav Sheshet: What is the halakha with regard to a son inheriting from his mother while he is in the grave, in order to bequeath that inheritance to his paternal brothers? If a son dies, and afterward his mother dies, does the deceased son inherit from his mother, and subsequently bequeath the inheritance to his paternal brothers, who are not related to the mother? Rav Sheshet said to them: You learned it in a baraita : Consider the case of a father who was taken captive and died in captivity, and his son died in the province, i.e., at home, and consider the case of a son who was taken captive and died, and his father died in the province. Since it is not known who died first, the father’s heirs and the son’s heirs divide the inheritance.
6The Gemara asks: What are the circumstances of the case? If we say that the case is as the baraita teaches, the baraita is difficult. Who are the father’s heirs and who are the son’s heirs? The same individuals inherit from both of them. Rather, is it not so that this is what the baraita is saying: Consider the case of a father who was taken captive and died in captivity, and his daughter’s son died in the province, and consider the case of the son of his daughter who was taken captive and died, and the father of the captive’s mother died in the province, and we do not know which of them died first. If the father died first, his daughter’s son inherits from him, and the son’s paternal relatives subsequently inherit from the son. If the son died first, the father’s heirs inherit the father’s estate. Since it is unknown which of them died first, the father’s heirs and the son’s heirs divide the inheritance.
7And if it is so that a son inherits from his mother while in the grave, although the son indeed died first, he should inherit from his mother’s father while in his grave and bequeath his inheritance to his paternal brothers, and the son’s heirs should receive the entire inheritance. Rather, isn’t it correct to conclude from the baraita that the son does not inherit from his mother while in the grave in order to bequeath that inheritance to his paternal brothers?
8Rav Aḥa bar Minyumi said to Abaye: We learn this halakha in the mishna (158b) as well: If the house collapsed on a son and upon his mother, both these Sages and those Sages, Beit Shammai and Beit Hillel, concede that the son’s heirs and the mother’s heirs divide the property between them. And if it is so that a son inherits from his mother while in the grave, although the son indeed died first, he should inherit from his mother while in his grave and they should inherit from him, i.e., he should bequeath his inheritance to his paternal brothers. Rather, isn’t it correct to conclude from that mishna that the son does not inherit from his mother while in the grave in order to bequeath that inheritance to his paternal brothers? The Gemara affirms: Conclude from the mishna that this is so.
9And what is the reason that a son does not inherit from his mother while in the grave? Abaye says: The term transfer, concerning the transfer of inheritance from one tribe to another, was stated with regard to the inheritance of a son (see Numbers 36:7), and the term transfer was stated with regard to the inheritance of a husband (see 111b–113a and Numbers 36:9). Just as in the case categorized as transfer that was stated with regard to the inheritance of a husband, the husband does not inherit from his wife while he is in the grave in order to bequeath that inheritance to his heirs, so too, in the case categorized as transfer that was stated with regard to the inheritance of a son, the son does not inherit from his mother while in the grave in order to bequeath that inheritance to his paternal brothers.
10§ There was a certain person who said to another: I am selling to you all of the property that I own of bar Sisin. There was one parcel of land that was called the tract of the house of bar Sisin. The seller said to the buyer: This latter parcel of land is actually not the property of the house of bar Sisin, and it is merely called: Of the house of bar Sisin, and therefore it is not included in the sale.
11The matter came before Rav Naḥman, and he placed the land in the possession of the buyer. Rava said to Rav Naḥman: Is this the halakha ? The halakha is that the burden of proof rests upon the claimant, which in this case is the buyer. And the Gemara raises a contradiction between this statement of Rava and another statement of Rava, and between this statement of Rav Naḥman and another statement of Rav Naḥman.
12The Gemara explains the contradictions. There was a certain man who said to another: What do you want, i.e., what are you doing, with this house of mine? He said to the claimant: I purchased it from you and I worked and profited from it for the years necessary for establishing the presumption of ownership. The claimant said to him: I was traveling among the settlements in a distant location, and I was unaware that you were residing in my house, which is why I did not lodge a protest.
13The one residing in the house came before Rav Naḥman for a judgment. Rav Naḥman said to him: Go clarify your profiting, i.e., prove that you really resided there for three years, and then the case can be judged. Rava said to Rav Naḥman: Is this the correct judgment? The halakha is that the burden of proof rests upon the claimant. Therefore, the claimant should have to prove that the possessor did not reside in the house. The first statement of Rava is difficult, as it is contradicted by the second statement of Rava, and the first statement of Rav Naḥman is difficult, as it is contradicted by the second statement of Rav Naḥman. In the first case, Rav Naḥman ruled in favor of the buyer, and Rava ruled in favor of the seller, whereas in the second case their rulings were reversed.
14The Gemara answers: The apparent contradiction between the first statement of Rava and the second statement of Rava is not difficult. Here, with regard to the property of bar Sisin, the seller stands in possession of his property, and the buyer claims the parcel of land from him. There, the buyer stands in possession of his property, since he dwells in the house, and the seller wishes to evict him.
15The contradiction between one statement of Rav Naḥman and the other statement of Rav Naḥman is not difficult as well, because there, since the seller said to him: I am hereby selling you all of the property that I own of the house of bar Sisin, and this parcel of land is called: Of the house of bar Sisin, it is incumbent on him to reveal that it is not of the house of bar Sisin. But here, in the case where the claimant states that he had been in a distant location, it should not be considered as any case other than one where the possessor is holding a document as evidence that he purchased the house. Wouldn’t we then say to him: First ratify your document, and only then be established as the owner of the property? In this case as well, since his presumptive ownership is in place of a document, he needs to clarify the matter by means of witnesses.
