אבן העזר קל״וEven HaEzer 136

Se’if 1א׳

הַמְגָרֵשׁ צָרִיךְ שֶׁיֹּאמַר כְּשֶׁיִּתֵּן לָהּ הַגֵּט: "הֲרֵי זֶה גִּטֵּךְ", וְכַיּוֹצֵא בָּזֶה. וְאִם נָתַן בְּיָדָהּ וְלֹא אָמַר כְּלוּם, הֲרֵי זֶה גֵּט פָּסוּל. הַגָּה: וּלְכַתְּחִלָּה יֹאמַר לָהּ: הֲרֵי זֶה גִּטֵּךְ (וְהִתְקַבְּלִי גִּטֵּךְ) (מָרְדְּכַי פ' הַמְגָרֵשׁ וּב"י בְּשֵׁם הַקֻנְטְרֵס) וַהֲרֵי אַתְּ מְגֹרֶשֶׁת מִמֶּנִּי וַהֲרֵי אַתְּ מֻתֶּרֶת לְכָל אָדָם (שָׁם וּבַטּוּר) מֵעַכְשָׁו (ב"י בְּשֵׁם י"א). וְנוֹהֲגִין שֶׁהַבַּעַל כּוֹפֵל הַגֵּט כְּמוֹ אִגֶּרֶת, וְנוֹתְנוֹ לָהּ, כְּדֵי שֶׁתּוּכַל לְאָחֲזוֹ כֻּלּוֹ בְּיָדָהּ כְּשֶׁנָתְנוֹ לָהּ. וְהַבַּעַל צָרִיךְ לֵידַע מַה הוּא אוֹמֵר לָהּ. וְכֵן כָּל מַה שֶּׁאוֹמֵר לָהּ, יוֹדִיעוּ אוֹתוֹ פֵרוּשׁוֹ (הַכֹּל בְּסֵדֶר גִּטִּין):

One who divorces must say when he gives her the divorce document, "Behold, this is your divorce document", or something similar. If he puts it in her hand and says nothing, the divorce document is invalid. Rama: Ideally he should say to her "Behold this is your divorce document (and I am accepting your divorce document) (Mordechai in chapter Hamgaresh and Bet Yosef in the name of HaKuntres) and behold you are divorced from me, and behold you are permitted [to remarry] any other person (ibid and Tur), from now on (Bet Yosef in the name of the Y"A)." We have the custom that the husband folds the divorce document like a letter, and gives it to her, so that she can grasp the entirety of it in her hand when he gives it to her. The husband must understand what he is saying to her. And so, anything he says to her, they must explain to him wgat it means (all in the Seder Gittin).

Se’if 2ב׳

בַּמֶּה דְּבָרִים אֲמוּרִים, בְּשֶׁלֹּא הָיָה מְדַבֵּר עִמָּהּ עַל עִסְקֵי גִּטָּהּ. אֲבָל אִם הָיָה מְדַבֵּר עִמָּהּ עַל עִסְקֵי גִּטָּהּ, וְנָטַל הַגֵּט וְנָתַן בְּיָדָהּ וְלֹא אָמַר כְּלוּם, הֲרֵי זֶה גֵּט:

When does this apply? When he had not discussed with her the process of her divorce document. But if he did discuss with her the process of her divorce document, and he takes the divorce document and puts it in her hand and says nothing, indeed that is a [valid] divorce document.

Se’if 3ג׳

כְּשֶׁיִּתֵּן לָהּ הַגֵּט יֹאמַר לָהּ: "הֲרֵי אַתְּ מְגֹרֶשֶׁת מִמֶּנִּי בְּגֵט זֶה וּמֻתֶּרֶת לְכָל אָדָם", אוֹ "הֲרֵי אַתְּ מְשֻׁלַּחַת מִמֶּנִּי". וְאִם שְׁלוּחוֹ נוֹתְנוֹ לָהּ, אוֹמֵר: "הֲרֵי אַתְּ מְגֹרֶשֶׁת מִפְּלוֹנִי בְּגֵט זֶה וַהֲרֵי אַתְּ מֻתֶּרֶת לְכָל אָדָם". וְאִם אָמַר: "אֵינִי אִישֵׁךְ", "אֵינִי בַּעְלֵךְ", יֵשׁ מִי שֶׁאוֹמֵר, שֶׁאֵינוֹ גֵּט, אֲפִלּוּ הָיָה מְדַבֵּר עִמָּהּ עַל עִסְקֵי גִּטָּהּ, דִּכְתִיב "וְשִׁלְּחָהּ" (דְּבָרִים כד, א ו ג) וְלֹא שֶׁיְּשַׁלַּח אֶת עַצְמוֹ. וְיֵשׁ מִי שֶׁאוֹמֵר, שֶׁאִם הָיָה מְדַבֵּר עִמָּהּ עַל עִסְקֵי גִּטָּהּ, הָוְיָא סְפֵק מְגֹרֶשֶׁת:

When he gives her the divorce document, he should say to her, "Behold you are divorced from me with this divorce document and permitted to [remarry] any other," or "Behold you are sent away from me." If his messenger gives it to her, he says, "Behold you are divorced from so-and-so with this divorce document, and behold you are permitted to [remarry] any other." If he says [instead], "I am not your spouse," or "I am not your husband," some say that is not a divorce, even if he discussed with her the process of the divorce, as it says (Deuteronomy 24:1, Deuteronomy 24:3) "And he sent her away", and not that he sent himself away. And some say that if he discussed the process of divorce with her, it is a divorce of doubtful [legality].
