3,431. Inheriting Tevel
Hilchos Maaser 6:21
Let’s say that a Yisroel inherits untithed produce from a grain pile that had been smoothed (i.e., its labor was completed) from his mother’s father, who was a kohein. The grandfather inherited it from his mother’s father, who was a Yisroel. In such a case, the current Yisroel may take the tithes and keep them. This is because gifts that are fit to be separated are considered to have been separated even if they were not separated in reality.
Hilchos Maaser 6:22
If someone gives his field for sharecropping to a non-Jew or to someone who cannot be relied upon to take tithes, he must take the tithes in their place even if the produce has not yet reached the stage of tithing. If he enters a sharecropping arrangement with an unlearned person before the produce reaches the tithing stage, the owner need not tithe in place of the sharecropper; if after it reached the tithing stage, he must tithe in the sharecropper’s place. In such a case, the owner stands over the grain pile and takes the tithes. He need not be concerned that the sharecropper may have eaten some of the untithed produce since he is not responsible for the sharecropper’s actions.
