Se’if 1א׳

צָרִיךְ שֶׁיַּחְתְּמוּ שְׁנֵי עֵדִים כְּשֵׁרִים זֶה תַּחַת זֶה (בְּמָרְדְּכַי הל' גִּטִּין) לְמַטָּה מִשִּׁיטָה אַחֲרוֹנָה שֶׁל גֵּט. וְלֹא יַנִּיחוּ כְּדֵי אֲוִיר שְׁנֵי שִׁיטִין בֵּין שִׁיטָה אַחֲרוֹנָה לַחֲתִימָתָם. הַגָּה: וְאִם הִנִּיחוּ, הַגֵּט פָּסוּל (טוּר). וְיֵשׁ חוֹלְקִין וּמַכְשִׁירִין עַל יְדֵי עֵדֵי מְסִירָה (הָרַמְבַּ"ם וְהָרַמְבַּ"ן וְהָרַשְׁבָּ"א וְהָרַ"ן) וְאִם חָתַם הָעֵד הָאַחֲרוֹן תְּחִלָּה, וְאַחַר כָּךְ חָתַם הָרִאשׁוֹן, כָּשֵׁר, אַף עַל פִּי דְּמִתְּחִלָּה הָיָה הַשֵּׁנִי חָתוּם שְׁנֵי שִׁיטוֹת מִן הַגֵּט (סֵדֶר גִּטִּין). וּמִכָּל מָקוֹם לְכַתְּחִלָּה לֹא יַעֲשׂוּ. יֵּשׁ אוֹמְרִים, דְּלְכַתְּחִלָּה אֵין לַחְתֹּם בַּגֵּט אֲפִלּוּ קָרוֹב וְנִתְרַחֵק אוֹ מְחֻתָּנִים בְּעָלְמָא (בְּסֵדֶר הַגֵּט בְּשֵׁם מַהֲרִי"ל). וְטוֹב לְהַדֵּר אַחַר הַסוֹפֵר שֶׁלֹּא יִהְיֶה קָרוֹב לָאִישׁ וְלָאִשָּׁה, אֲבָל הֵיכָא דְּלָא אֶפְשָׁר אֵין קְפִידָא בַּדָּבָר (מַהֲרִי"ק ק"ו). וְלֹא יְהֵא אֶחָד מִן הָעֵדִים חָשׁוּד בַּעֲרָיוֹת. וְיֵשׁ מַחֲמִירִין שֶׁלֹּא יִהְיֶה בַּעַל מוּם, וְשֶׁלֹּא יִהְיוּ הָעֵדִים קְרוֹבִים לַסוֹפֵר, וְכֻלָּם לֹא יִהְיוּ קְרוֹבִים לָרַב הַמְסַדֵּר הַגֵּט, וְטוֹב לָחוּשׁ לְכָל זֶה לְכַתְּחִלָּה (כָּל זֶה בִּסְדָרִים). גַּם נוֹהֲגִין לִקַּח עֵדֵי חֲתִימָה לְעֵדֵי מְסִירָה, וְהֵם יִרְאוּ שֶׁהַבַּעַל צִוָּה לַסוֹפֵר לִכְתֹּב, כְּדֵי שֶׁיִּהְיֶה הַכֹּל נַעֲשֶׂה בִּפְנֵי כַּת אַחַת שֶׁל עֵדִים (בְּמָרְדְּכַי הל' גִּטִּין וּבַסְמַ"ג). וְלֹא יַחְתְּמוּ הָעֵדִים רַק בִּדְיוֹ וְקוּלְמוּס שֶׁל בַּעַל, כְּמוֹ הַסוֹפֵר (בִּסְדָרִים), וּכְמוֹ שֶׁנִּתְבָּאֵר לְעֵיל רֵישׁ סִימָן ק"כ:

One needs to sign [get] in front of two kosher witnesses, and they should sign one signature under the other (Mordechai Halachos Gitin), both under the last line of the get. But don't leave space that is two lines worth of space between the last line [of the get] and their signature. If they place it so [see statement above], the get is void (Tur). There are those who disagree, and say that it is still made kosher by the witnesses [those who see that the man gave the get] (Rambam). If the second witness signs first, and the first witness signs after, it is still kosher, even though from the beginning, there were two signatures, two lines away from the get (Gittin). Nevertheless, initially, you shouldn't do so. If you say that initially, one should not sign the get if they have been related and now distanced, or if you were the matchmaker (Seder HaGet Bisheim Maharil). It's good to praise the scribe, so the scribe will not come close to the man and his wife, but when this is impossible, you need not be stringent (Maharik 106). And none of the witnesses may be suspects of adultery. There are those that are stringent that he [the witness] cannot have a blemish, and he should not be related to the scribe, and none of the witnesses may be related to the Rabbi officiating the get , and it's also good to be suspicious of all this from the beginning. Also, it is customary to take signers and the witnesses to see that the husband commanding the scribe to write [the get ], so all this will be in the presence of one group of witnesses (Mordechai Halachos Gittin and in the Smag). And the witnesses shouldn't sign unless it is [they are signing] with the quill and ink of the husband, like the scribe, as was explained earlier in the beginning of the siman .

Se’if 2ב׳

יַתְחִיל בְּרֹאשׁ שִׁיטָה, שֶׁלֹּא יִשָּׁאֵר חָלָק בְּגִלְיוֹן הַגֵּט לִפְנֵי חֲתִימָתָן:

He shall start at the beginning of a line: no blank space shall be left in the margin before their signature[s].

Se’if 3ג׳

לֹא יִהְיֶה בֵּין הַגֵּט לַחֲתִימַת הָעֵדִים כָּתוּב דָּבָר שֶׁאֵינוֹ מֵעִנְיַן הַגֵּט. וְאִם כָּתוּב כֵּן, כְּגוֹן שֶׁכָּתוּב: שַׁאֲלוּ בִּשְׁלוֹמָהּ, פָּסוּל, שֶׁמָּא לֹא חָתְמוּ אֶלָּא עַל שְׁאֵלַת שָׁלוֹם. אֲבָל אִם כָּתַב: וְשַׁאֲלוּ בִּשְׁלוֹמָהּ), כָּשֵׁר, שֶׁהִיא מְדֻבָּק עִם שֶׁל מַעְלָה וְעַל הַכֹּל חָתְמוּ:

Between the text of the get (writ of divorce) and the signature of the witnesses there should be nothing written which is not relevant to the get. And if there is something written there, such as "inquire as to her welfare," the get is invalid, for maybe the witnesses only signed on to the welfare inquiry [and not the get]. But if he wrote "and inquire as to her welfare," the get is valid, for the phrase is attached to the text above, and the witnesses signed on everything.
