R. Yustini once wrote such a document, relinquishing his claim on her property, and the case came before the Rabbanan, who ruled against him (that the stipulation is valid). However, R. Yustini then came before Raish Lakish who told him that he may take her property.

Question (R. Yirmiyah to R. Zeira): If Rav ruled that we ignore the stipulation and R. Yochanan ruled like Rabban Shimon ben Gamliel that the husband does inherit her...who are these Rabbanan that ruled against R. Yustini?

Answer: Other Rabbis.

Beraisa: The pasuk states (Bamidbar 27:11), "and he will inherit her'' - I might think that just as he inherits her, so she inherits him, the pasuk says "her'' - he inherits her but she does not inherit him.

R. Yochanan: According to the Chachamim (above 131- (a)) her father inherits her or her brothers inherit her.

Question (R. Ba bar Mamal): If you say that it is not Torah law that a husband inherits his wife, a man should also inherit his betrothed wife (MiD'Rabbanan)?

Answer: Just as you say that the word "kerovah'' excludes inheriting his ex-wife, so it excludes inheriting his betrothed wife.

Question (Rav Hamnuna): If you say that it is not Torah law that a husband inherits his wife, a husband should inherit even property of his wife that was not yet in her possession...So why did R. Yosi say that Rebbi taught that a husband does not inherit his wife's property that was not yet in her possession?

Answer (R. Yosi bei R. Bun): It is Torah law that even though a firstborn inherits a double portion, he does not inherit any property that was not yet in the father's possession.

R. Yitzchak: Those that write in their Kesuvah that if the wife will die without children, all of her property will be returned to her father, even though it is a stipulation against the Torah, it is valid, since it is a monetary stipulation.

The pasuk states (Divrei Hayamim I 2:22), "And Seguv bore Yair (and he had 23 cities in the land of Gilad)'' - this implies that only Yair had them but not Seguv. If his father did not have them, from where did Yair get them? Rather, he married a daughter of (the tribe of) Menashe and she later died and he inherited her. If you say that it is not Torah law that a husband inherits his wife, the pasuk should say "and Seguv had''; why did it say, "he had''? It refers to Yair. (This is therefore a proof that a husband inherits his wife.)

Similarly, the pasuk states (Yehoshua 24:33), "And Elazar ben Aharon died (and they buried him in the hill of his son Pinchas)''. This implies that the hill only belonged to Pinchas but not to his father. Rather, Pinchas married a daughter of (the tribe of) Ephraim and later inherited her. If you say that it is not Torah law that a husband inherits his wife, it should say that "Elazar had''; why did say that "Pinchas had''? (This shows that Pinchas inherited his wife.)
