Jerusalem Talmud Bava Batra 10.9

משנה: כְּיוֹצֵא בוֹ הָיָה רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר אַף הֶעָרָב לָאִשָּׁה בִּכְתוּבָּתָהּ וְהָיָה בְעָלֶיהָ מְגָרְשָׁהּ יַדִּירֶנּוּ הֲנָיָיה שֶׁמָּא יַעֲשׂוּ קָיְנוֹנִיָיא עַל נְכָסִים שֶׁל זֶה וְיַחֲזִיר אֶת אִשְׁתּוֹ.

MISHNAH: Similarly did Rabban Simeon ben Gamliel say that if a person was guarantor for a woman’s ketubah and her husband divorced her, the latter has to make a vow not to have any usufruct from her so they could not plan a partnership against that person’s property and then he would take back his wife.

הלכה: כְּיוֹצֵא בוֹ הָיָה רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל כול׳. חָמוֹי דִבְרַתֵּיהּ דְּרִבִּי חַגַּיי הֲוָה עֲרָבָא בְּפוֹרְנָהּ דִּבְרַתֵּיהּ דְּרִבִּי חַגַּיי וַהֲוָה מְבַזְבְּזָה בְנִכְסַיָיא. אֲתַא עוֹבְדָא קוֹמֵי רִבִּי אָחָא. אָמַר. צָרִיךְ לְהַדִּיר הֲנָיָיה. אָמַר רִבִּי יוֹסֵי. אֵין צָרִיךְ לְהַדִּיר הֲנָיָיה. אָמְרִין חֲבֵרַיָיה קוֹמֵי רִבִּי יוֹסֵי. וּמַה אִילּוּ דְּיַחְזוֹר וְיִסְבִּינָהּ לֵית מָרֵי חוֹבָה אֲתִי וְטָרִף. אֲמַר. דְּלָא יַחְזוֹר. וְיַעַבְדִּינוֹן מִטַּלְטְלִין אוֹ פָּרָאפֶרְנוֹן וְלָא מַשְׁכַּח מָרֵי חוֹבָא מַה מִתְפַּס. וּנְפַק עוֹבְדָא כְרִבִּי אָחָא.

HALAKHAH: “Similarly did Rabban Simeon ben Gamliel say,” etc. The father-in-law of Rebbi Ḥaggai’s daughter was guarantor for Rebbi Ḥaggai’s daughter’s ketubah. She turned out to be a spendthrift. The case came before Rebbi Aḥa, who said that he would have to make a vow not to have usufruct. Rebbi Yose said, he does not have to make a vow not to have usufruct. The colleagues said before Rebbi Yose, but if he would take her back, the creditor would come and seize it. He said, he would not take her back. But it could be transformed into movables or paraphernalia which the creditors could not seize. The case was decided following Rebbi Aḥa.
