Gitin8: 10
גֵּט קֵרֵחַ — הַכֹּל מַשְׁלִימִין עָלָיו; דִּבְרֵי בֶן נַנָּס. רַבִּי עֲקִיבָא אוֹמֵר: אֵין מַשְׁלִימִין עָלָיו אֶלָּא קְרוֹבִים, הָרְאוּיִין לְהָעִיד בְּמָקוֹם אַחֵר. וְאֵיזֶהוּ גֵּט קֵרֵחַ? כֹּל שֶׁקְּשָׁרָיו מְרֻבִּין מֵעֵדָיו.
10. A “bald” get may be completed by anyone; [these are] the words of Ben Nannas. R' Akiva says: No one may complete it, except relatives, who are qualified to testify elsewhere. What is a “bald” get? Any whose bindings are more than its witnesses.
Gitin9: 1
הַמְגָרֵשׁ אֶת אִשְׁתּוֹ וְאָמַר לָהּ: ,,הֲרֵי אַתְּ מֻתֶּרֶת לְכָל אָדָם, אֶלָּא לִפְלוֹנִי” — רַבִּי אֱלִיעֶזֶר מַתִּיר, וַחֲכָמִים אוֹסְרִין. כֵּיצַד יַעֲשֶׂה? יִטְּלֶנּוּ הֵימֶנָּה וְיַחֲזֹר וְיִתְּנֶנּוּ לָהּ, וְיֹאמַר לָהּ: ,,הֲרֵי אַתְּ מֻתֶּרֶת לְכָל אָדָם”. וְאִם כְּתָבוֹ בְתוֹכוֹ — אַף עַל פִּי שֶׁחָזַר וּמְחָקוֹ, פָּסוּל.
[If] one divorced his wife and said to her: “You are permitted to every man, except So-and-so” —- R' Eliezer permits [her]; the Sages, however, prohibit [her]. What shall he do? He must take it from her and give it to her again, and say to her: “You are permitted to every man.” If he wrote it inside it, although he subsequently erased it, it is void.
