Just as a widow can sell [her ketubah] without the court, so too can her inheritors [or] those who come with her permission sell [it] without the court. Said Rabbi Shimon: Why did they say that a widow can sell [it] without the court? In order to benefit the orphans, such that they shouldn't plunder their property [if they have to wait to go to court, they will be using up their property in the meantime, so they said that they don't need a court and can sell the ketubah immediately]. If she took possession of a field that was made a security [for her ketubah] and ate it [i.e. used up the value of the property], but profits came out of it—they evaluate for her what she ate, and evaluate for her the profits [just like someone who took possession of a field without permission]. If they evaluate for her in a court, whatever they evaluated is evaluated.
