הַמּוֹצֵא גֵּט אִשָּׁה בַּשּׁוּק, אִם הָאִשָּׁה נוֹתֶנֶת סִימָן, שֶׁאוֹמֶרֶת: נֶקֶב יֵשׁ בְּצַד אוֹת פְּלוֹנִי, וְאוֹמֶרֶת שֶׁכְּבָר נִתְגָּרְשָׁה בּוֹ וּמִמֶּנָּה נָפַל, יַחֲזִירוּהוּ לָהּ, אֲפִלּוּ אִם הַבַּעַל מַכְחִישָׁהּ וְאוֹמֵר שֶׁמִּמֶּנּוּ נָפַל וְלֹא גֵּרְשָׁהּ מֵעוֹלָם אֶלָּא שֶׁצִּוָּה לְכָתְבוֹ וַעֲדַיִן לֹא נְתָנוֹ; אֲפִלּוּ אִם גַּם הוּא נוֹתֵן בּוֹ סִימָן. וְאִם אֵינָה נוֹתֶנֶת בּוֹ סִימָן, וְהַבַּעַל מַכְחִישָׁהּ, לֹא יִתְּנוּהוּ לֹא לוֹ וְלֹא לָהּ. וְאִם הַבַּעַל מוֹדֶה שֶׁכְּתָבוֹ, וְאוֹמֵר שֶׁיִּתְּנוּהוּ לָהּ לְהִתְגָּרֵשׁ, בְּמָקוֹם וּבְשָׁעָה שֶׁרָאוּי לְהַחֲזִיר, דְּלֵיכָּא לְמֵיחַשׁ שֶׁמֵּאַחֵר נָפַל עַל פִּי מַה שֶּׁנִּתְבָּאֵר בְּסִימָן קל"ב, יִתְּנוּהוּ לָהּ וְתִתְגָּרֵשׁ בּוֹ מֵעַתָּה; וְאִם לָאו, לֹא יִתְּנוּהוּ לָהּ. וְאִם הוּא מוֹדֶה שֶׁנִּתְגָּרְשָׁה בּוֹ, וְהִיא שׁוֹאֶלֶת אוֹתוֹ לִגְבּוֹת בּוֹ כְּתֻבָּתָהּ, וְהוּא אוֹמֵר שֶׁכְּבָר פְּרָעָהּ וְהֶחֱזִירַתּוּ לוֹ וּמִמֶּנּוּ נָפַל, מַחֲזִירוֹ לָהּ, אֲפִלּוּ אֵינָהּ אוֹמֶרֶת: נֶקֶב יֵשׁ בְּצַד אוֹת פְּלוֹנִית, רַק בִּשְׁאָר סִימָן (שֶׁאֵינוֹ כָּל כָּךְ) מֻבְהָק, כְּגוֹן שֶׁאוֹמֶרֶת: כָּךְ וְכָךְ אֶצְבָּעוֹת בְּאֹרֶךְ הַגֵּט אוֹ בְּרָחְבּוֹ, אוֹ שֶׁאוֹמֶרֶת מִדַּת הַחוּט הַקָּשׁוּר בּוֹ. אֲבָל אִם אָמְרָה: הַגֵּט הָיָה אָרֹךְ אוֹ קָצָר, וְאֵינָהּ מְכַוֶּנֶת מִדָּתוֹ, אוֹ הַחוּט לָבָן אוֹ שָׁחֹר, אוֹ שֶׁאָמְרָה שֶׁהוּא מֻנָּח בַּחֲפִיסָה אוֹ בִּדְלוֹסְקְמָא, אֵינוֹ סִימָן לְהַחֲזִירוֹ לָהּ עַל יָדוֹ:

If someone finds a woman's bill of divorce in the marketplace, if the woman gives a sign [it is hers], saying, "This hole is next to this letter," and she says she was already divorce with it and it fell off of her, they return it to her. [This is so] even if the husband contradicts her and says that it fell off of him and that he never divorced her ever, but rather he had commanded it to be written but he had yet to give it; even if he also gives a sign. If she does not give a sign, and the husband contradicts her, they don't give it to him, nor to her. And if the husband admits he wrote it, and says he they should give it to her for divorce, at a place and time that it is appropriate to return, for there is not what to suspect after it fell, according to what was explained in Siman 132, they can give it to her and she can be divorced from then on. If not, they should not give it to her. And if he admits he divorced her with it, and she requests of him that she should collect her ketubah, and he said that he already paid her and returned it to her and [the bill of divorce] fell from him, he returns it to her, even if she doesn't say, "This hole is next to this letter," but any other sign (that does not so much) show intimate knowledge [of what the bill of divorce looks like], such as her saying, "Such and such fingers are the length of the bill of divorce," or "[Such and such fingers are the width of the bill of divorce," or she says the measurement of the string-tie for it, or [whether] the string is white or black, or she says it was placed in a box or in a chest, those are not sign that are enough for him to return it to her.
