עָרֵב דְּבֵית דִּין הוּא דְּלָא בָּעֵי קִנְיָן, הָא בְּעָלְמָא בָּעֵי קִנְיָן.	It is only a guarantor who undertakes a loan guarantee in the presence of a court who does not require an act of acquisition; this indicates that generally, a guarantor requires an act of acquisition in order to be obligated to pay.
וְהִלְכְתָא: עָרֵב בִּשְׁעַת מַתַּן מָעוֹת – לֹא בָּעֵי קִנְיָן, אַחַר מַתַּן מָעוֹת – בָּעֵי קִנְיָן. עָרֵב דְּבֵית דִּין – לָא בָּעֵי קִנְיָן; דִּבְהָהִיא הֲנָאָה דִּמְהֵימַן לֵיהּ – גָּמַר וּמְשַׁעְבֵּד לֵיהּ.	The Gemara concludes: And the halakha is that a guarantor who accepts responsibility for the loan at the time of the giving of the money does not require an act of acquisition; but if he accepts responsibility after the giving of the money, he requires an act of acquisition. Moreover, a guarantor who undertakes a loan guarantee in the presence of a court does not require an act of acquisition, as in return for that gratification that he experiences in that the court trusts him, he resolves to obligate himself.
