הָהוּא אַרְבָּא דַּהֲווֹ מִינְּצוּ עֲלַהּ בֵּי תְרֵי הַאי אָמַר דִּידִי הִיא וְהַאי אָמַר דִּידִי הִיא אֲתָא חַד מִינַּיְיהוּ לְבֵי דִינָא וְאָמַר תִּיפְסוּהָ אַדְּמַיְיתֵינָא סָהֲדֵי דְּדִידִי הִיא תָּפְסִינַן אוֹ לָא תָּפְסִינַן רַב הוּנָא אָמַר תָּפְסִינַן רַב יְהוּדָה אָמַר לָא תָּפְסִינַן § The Gemara relates: There was a certain boat that two people were quarreling about with regard to its ownership. This one said: It is mine, and that one also said: It is mine. One of them came to court and said: Seize it until I am able to bring witnesses that it is mine. The Gemara asks: In such a case, do we seize it or do we not seize it? Rav Huna said: We seize it. Rav Yehuda said: We do not seize it, as there is no cause for the court to intervene.
אֲזַל וְלָא אַשְׁכַּח סָהֲדֵי אֲמַר לְהוּ אַפְּקוּהָ וְכֹל דְּאַלִּים גָּבַר מַפְּקִינַן אוֹ לָא מַפְּקִינַן רַב יְהוּדָה אָמַר לָא מַפְּקִינַן רַב פָּפָּא אָמַר מַפְּקִינַן וְהִלְכְתָא לָא תָּפְסִינַן וְהֵיכָא דִּתְפַס לָא מַפְּקִינַן: The court seized the boat. The one who requested of the court to seize it went to seek witnesses, but did not find witnesses. He then said to the court: Release the boat, and whoever is stronger prevails, as this is the ruling in a case where there is neither evidence nor presumptive ownership for either litigant. The Gemara asks: In such a case, do we release it or do we not release it? Rav Yehuda said: We do not release it. Rav Pappa said: We release it. The Gemara concludes: And the halakha is that we do not seize property in a case where ownership is uncertain, and where it was seized, we do not release it.
זֶה אוֹמֵר שֶׁל אֲבוֹתַי וְזֶה אוֹמֵר שֶׁל אֲבוֹתַי אָמַר רַב נַחְמָן כֹּל דְּאַלִּים גָּבַר וּמַאי שְׁנָא מִשְּׁנֵי שְׁטָרוֹת הַיּוֹצְאִין בְּיוֹם אֶחָד There was an incident where two people dispute the ownership of property. This one says: It belonged to my ancestors and I inherited it from them, and that one says: It belonged to my ancestors and I inherited it from them. There was neither evidence nor presumptive ownership for either litigant. Rav Naḥman said: Whoever is stronger prevails. The Gemara asks: And in what way is this case different from the case where two people produce two deeds of sale or gift for the same field that are issued on one day,
