Talmud - Bava Batra 172a בבא בתרא קע״ב א׳

But today, when we do not do this either when writing receipts, how can we avoid double collection of a loan? Rav Kahana said to him: The Sages instituted taking this precaution. One who does what the Sages instituted does it and protects himself from loss; and as for one who does not do so, he has brought the loss upon himself, and will suffer the consequences if the promissory note is found and presented in the future.

Rava bar Rav Sheila said to those who wrote deeds of acquisition, i.e., deeds of sale or deeds of gifts for property they acquired: When you write deeds of acquisition after the acquisition was performed, if you know the day on which you effected the acquisition, write that date on the document. But if you do not know the day on which you effected the acquisition, write the date on which you are currently writing the document. You should follow this procedure, and not write an approximate or estimated date, so that the document shall not appear as a falsehood.

Rav said to his scribe, and Rav Huna said similarly to his scribe: When you are writing a document and you are situated in Shili, write that the document was written in Shili, and you should do so even if the matters were given over to you, i.e., the transaction attested to in the document took place, in Hini. When you are situated in Hini, write that the document was written in Hini, even if the matters were given over to you in Shili.

§ Rava said: With regard to this one who is holding a promissory note of one hundred dinars, and he says to the court: Prepare this note for me, i.e., exchange it, for two notes of fifty dinars each, so that if the debtor pays half the debt I will be able to give him one document and keep the other, we do not prepare the new notes for him.

What is the reason? The Sages have performed a matter here that is beneficial to the creditor and is beneficial to the debtor as well. It is beneficial to the creditor to keep the promissory note with the larger sum so that he can coerce the debtor to repay him, as there is a greater incentive to pay off a larger promissory note than a smaller one. And it is beneficial to the debtor, so that when he pays half the debt his promissory note becomes vitiated, and the remainder of the sum written in the vitiated promissory note can be collected only if the creditor takes an oath that he has not received the entire sum.

And Rava said further: With regard to this one who is holding two promissory notes, each of fifty dinars, owed by the same person, and he says to the court: Prepare this note for me into a single note of one hundred dinars, we do not prepare the new note for him.

What is the reason? The Sages have performed a matter here that is beneficial to the creditor and is beneficial to the debtor as well. It is beneficial to the creditor to keep the smaller notes, so that if the debtor pays fifty dinars, his promissory note will not become vitiated, which would require the creditor to take an oath before collecting the remainder. And it is beneficial to the debtor, so that the creditor will not be able to coerce him to repay the debt quickly, as there is a greater incentive to repay a larger sum than a smaller one.

Rav Ashi says: With regard to this one who is holding a promissory note of one hundred dinars, and he said to the court: Prepare this note for me into one note of fifty dinars, as the debtor has paid me half, we do not prepare the new note for him.

What is the reason? We say, i.e., we are concerned, that the following may have happened: This debtor actually repaid all one hundred dinars, and when he did so he said to the creditor: Give me back my promissory note. And the creditor said to him: I lost it. And the creditor wrote a receipt for him in lieu of handing over the promissory note. And now, if we write a new promissory note of fifty dinars for the creditor, he will present this note and say to the debtor, who presents his receipt for a hundred dinars: That receipt is for a different loan that you repaid.

MISHNA: In a case where there are two brothers, one poor and one rich, and their father left them a bathhouse or an olive press as an inheritance, if the father had built these facilities for profit, i.e., to charge others for using them, the profit that accrues after the father’s death is shared equally by the two brothers. If the father had built them for himself and for the members of his household to use, the poor brother, who has little use for these amenities, cannot force the rich brother to convert the facilities to commercial use; rather, the rich brother can say to the poor brother: Go take servants for yourself, and they will bathe in the bathhouse. Or he can say: Go take olives for yourself, and come and make them into oil in the olive press.

If there are two people who were living in one city, one named Yosef ben Shimon and the other also named Yosef ben Shimon, one cannot present a promissory note against the other, as the purported debtor can claim: On the contrary, it is you who owed me money; you repaid me and I returned this note to you upon payment. Nor can another, third person, present a promissory note against either of them, as each one can claim: It is not I but the other Yosef ben Shimon who owes you money.

If a document is found among one’s documents stating: The promissory note against Yosef ben Shimon is repaid, and both men named Yosef ben Shimon owed this man money, the promissory notes of both of them are considered repaid, as it cannot be determined which debt was repaid and which is outstanding.

What should two people with the same name in a single city do in order to conduct their business? They should triple their names by writing three generations: Yosef ben Shimon ben so-and-so. And if they have identical triple names, i.e., not only their fathers but their grandfathers had identical names, they should write an indication as to which one is referred to, such as: The short Yosef ben Shimon or the dark Yosef ben Shimon. And if they have identical indications, they should write: Yosef ben Shimon the priest, if one of them is a priest.

GEMARA: There was a certain promissory note that was presented at the court of Rav Huna, in which it was written: I, so-and-so son of so-and-so, borrowed one hundred dinars from you. No name was given as the creditor, but the one presenting the document claimed that the money was owed to him.
