[If there were] two brothers, one poor and one wealthy, and their father left them a bathhouse or an olive press —- [if] he had made them for renting, the rent is divided; [if] he made them for themselves, the wealthy one can say to the poor one, “Ac-quire servants, and let them bathe in the bathhouse; acquire olives, and come process them in the olive press.”  Two people in the same town, both named Yosef ben Shimon, cannot produce a document of indebtedness against each other; nor can another produce a document of indebtedness against them. [If] one found among his documents [a receipt stating], “The note of Yosef ben Shimon is paid,” both their notes are [treated as] paid. What should they do? They should [record] the third [gen-eration]. If they were [identical] for three [generations], they should write a description. If they were alike, they should write “Kohen.”  If someone said to his son, “One of my notes is paid, but I do not know which,” all the notes are paid. [If] two [notes] from one person were found there, the larger one is [treated as] paid and the smaller one is not [considered] paid.  One who lends to another through a guarantor may not collect from the guarantor. If he said, “On condition that I can collect from whomever I wish,” he may collect from the guarantor. Rabban Shimon ben Gamliel says: In either case, if the borrower has property, he may not collect from the guarantor. Similarly, Rabban Shimon ben Gamliel said: [If one was] the guarantor of a woman's kesubah, and her husband was divorc-ing her, he must vow not to derive any [further] benefit from her, to prevent them from plotting against this one's property and [then] remarrying.
