If the son sold [property written to him by his father for after his death] and (sic! according to Ehrfurt manuscript and most Rishonim, see Lieberman's notes) his father died, if there is property [still] attached to the ground [i.e. that the buyer has not used in the meantime], they evaluate for him [i.e. the property returns to the inheritors, but the buyer gets a certain amount of money as if he were a tenant, see end of this halakhah, also Lieberman and Tosefta Ketubot 8:4 above]. One who receives a field from his fellow [and then the original owner wants it back] which is an irrigated field or orchard [two types of field that are a lot of work to look after], if there is property attached to the ground, they evaluate for him [as a tenant]. One who receives a field from his fellow and the 7th year arrives, if there is property attached to the ground, they evaluate for him. (The following is not in the printed edition but supplied by Ehrfrut manuscript:) One who receives a field from his fellow and the time arrives when he has to leave, if there are [property] attached to the ground, they evaluate for him. And for all of these, they evaluate them as if he were a tenant.

Rabbi Yehudah says: [The husband] can always eat the fruits' fruit [i.e. the interest's interest, even if he said in the ketubah that he gives up access to the fruit from her property]. How so? He can sell the fruit and buy with [that money] land, and he can eat the fruit. Rabban Shimon ben Gamliel and Rabbi Yohanan ben Berokah say: If she dies, he inherits it [the fruit, even if he said he wouldn't have access to it in the ketubah], for she made a stipulation against what was written in the Torah and anyone who stipulates against what is written in the Torah, his stipulation is null and void.
