An adult woman and a woman incapable of having children (aylonit)—their ketubah is 200. If she is married on the presumption that she was fit to bear children but it turned out that she was incapable, she has no ketubah. If he wants to uphold it, he gives a ketubah of 100 zuz.

She [a widow] that sold something worth 101 zuz for 100, even if she says "I will return the [extra] zuz to the inheritors"—her sale is null and void. Rabban Shimon ben Gamliel says: Her sale certainly stands, and she should return the zuz to the inheritors; and [her sale is void] only if there was some left over [from the sale that she did not give to the inheritors]. Therefore, if she reduced or added [to the price of the property she is selling], she only has the price that she sold it [and has to return the excess to the inheritors]. (Based on Ehrfurt manuscript:) Rabbi Liezer: An orphan girl has [the right to] worn out clothes [like a widow]. Rabbi Yehudah said in the name of Rabbi Liezer: An orphan girl has [the right to] fruit [i.e. interest from her property].
