He shall not say to her: “Your kesubah is lying on the table”; rather, all his property is surety for the kesubah. Likewise, a man shall not say to his wife, “Your kesubah is lying on the table”; rather, all his property is surety for her kesubah. [If] he divorced her, she is entitled only to her kesubah. [If] he remarried her, she is like all [other] women; she is entitled only to her kesubah.

[If] one writes to his wife: “I have neither right nor claim to your property,” he may [nevertheless] enjoy the usufruct during her lifetime. If she dies, he inherits her. If so, why did he write to her: “I have neither right nor claim to your property”? That if she sold [it] or gave [it] away, [the act] is valid.  [If] he wrote to her: “I have neither right nor claim to your property or its usufruct,” he does not enjoy the usufruct during her lifetime; but if she dies, he inherits her. R’ Yehudah says: He may always enjoy the usufruct of the produce unless he writes to her: “I have neither right nor claim to your property or its produce or the usufruct of its produce forever.”  [If] he wrote to her: “I have neither right nor claim to your property or its produce or the usu-fruct of its produce during your lifetime and after your death,” he does not enjoy the usufruct during her lifetime; and if she dies, he does not inherit her. Rabban Shimon ben Gamliel says: If she dies, he inherits her, because he stipulated on what is written in the Torah, and whoever stipulates on what is written in the Torah, his stipulation is void.
