A person's statements regarding his relatives affect his share of an inheritance, but not that of his brothers. To illustrate by example: Jacob died and left two sons: Reuven and Shimon. The prevailing presumption was that he did not have any sons other than these two. Reuven took Levi from among people at large and said: "He is also our brother." Shimon replied: "I don't know." Shimon is granted half the estate. Reuven is given a third, for he acknowledged that they are three brothers, and Levi is given a sixth. If Levi dies, that sixth is returned to Reuven. If other property had been acquired by Levi, it should be divided between Reuven and Shimon, for Reuven acknowledges Shimon's claim to a portion of the estate, because Levi is their brother. Different rules apply if the sixth that Levi was given increased in value on its own accord and then Levi died. If the increase were crops that were almost ready to be reaped - e.g., grapes that are ready to be harvested - they are considered to be property acquired from others and should be divided among the two brothers. If they are not ready to be reaped, they belong to Reuven alone. If Shimon said explicitly: "Levi is not my brother," and Levi received part of Reuven's share, as explained above, and then died, Shimon should not inherit any part of his estate. Instead, Reuven should inherit both the sixth from his share and any other property that Levi left. These principles apply with regard to any other heirs when a portion of them acknowledge the existence of other heirs that the remaining portion do not acknowledge.
