הַתּוֹבֵעַ חֲבֵרוֹ בְּמָמוֹן שֶׁאִם הוֹדָה בּוֹ יִהְיֶה חַיָּב לְשַׁלֵּם וְכָפַר וְנִשְׁבַּע. אוֹ שֶׁהִשְׁבִּיעוֹ הַתּוֹבֵעַ וְכָפַר. הֲרֵי זֶה הַנִּתְבָּע הוּא חַיָּב בִּשְׁבוּעַת הַפִּקָּדוֹן אַף עַל פִּי שֶׁלֹּא עָנָה אָמֵן. שֶּׁבִּשְׁבוּעַת הַפִּקָּדוֹן אֶחָד הַנִּשְׁבָּע מִפִּי עַצְמוֹ וְאֶחָד שֶׁהִשְׁבִּיעוֹ אַחֵר וְכָפַר אַף עַל פִּי שֶׁלֹּא עָנָה אָמֵן חַיָּב. שֶׁכְּפִירָתוֹ אַחַר שֶׁהִשְׁבִּיעוֹ הַתּוֹבֵעַ כַּעֲנִיַּת אָמֵן:
When a person issues a financial claim against a colleague which would require the latter to pay were he to admit [liability] and [the colleague] denies [his obligation] and takes an oath or the plaintiff administers an oath to him and he denies [any obligation]. [If he is lying,] the defendant is liable for an oath concerning a sh'vuat hapikadon. [The above applies] even if [the defendant] does not respond Amen. For with regard to a sh'vuat hapikadon, one is liable whether he took the oath on his own initiative or another person administered the oath to him and he denied [any obligation], even though he did not respond Amen. For denying the claim after the plaintiff administered the oath is equivalent to responding Amen.
