מִי שֶׁאֲנָסוּהוּ עַד שֶׁמָּכַר וְלָקַח דְּמֵי הַמִּקָּח. אֲפִלּוּ תָּלוּהוּ עַד שֶׁמָּכַר מִמְכָּרוֹ מִמְכָּר בֵּין בְּמִטַּלְטְלִין בֵּין בְּקַרְקָעוֹת שֶׁמִּפְּנֵי אָנְסוֹ גָּמַר וּמַקְנֶה. אַף עַל פִּי שֶׁלֹּא לָקַח הַדָּמִים בִּפְנֵי הָעֵדִים. לְפִיכָךְ אִם מָסַר מוֹדָעָה קֹדֶם שֶׁיִּמְכֹּר וְאָמַר לִשְׁנֵי עֵדִים דְּעוּ שֶׁזֶּה שֶׁאֲנִי מוֹכֵר חֵפֶץ פְּלוֹנִי אוֹ שָׂדֶה פְּלוֹנִי לִפְלוֹנִי מִפְּנֵי שֶׁאֲנִי אָנוּס. הֲרֵי הַמִּמְכָּר בָּטֵל. וַאֲפִלּוּ הֶחֱזִיק כַּמָּה שָׁנִים מוֹצִיאִין אוֹתָהּ מִיָּדוֹ וּמַחֲזִיר הַדָּמִים:
When a person compels a colleague to sell an article and to take the money for the purchase - even if he hung him until he sold the article - the purchase is binding. This applies with regard to movable property and landed property. We say that since he compelled him, he committed himself to selling. This applies even if the seller did not take the money in the presence of witnesses. Therefore, if the seller issues a protest before he sells and tells two witnesses: "Know that the reason I am selling this and this article - or this and this property - is that I am being compelled against my will," the sale is nullified. Even if the purchaser was in possession of the article or the property for several years, it may be expropriated from him, at which point, the seller returns the money.
