Reference for Ketubot 13:11
הַכֹּל מַעֲלִין לְאֶרֶץ יִשְׂרָאֵל, וְאֵין הַכֹּל מוֹצִיאִין. הַכֹּל מַעֲלִין לִירוּשָׁלַיִם, וְאֵין הַכֹּל מוֹצִיאִין, אֶחָד הָאֲנָשִׁים וְאֶחָד הַנָּשִׁים (וְאֶחָד עֲבָדִים). נָשָׂא אִשָּׁה בְאֶרֶץ יִשְׂרָאֵל וְגֵרְשָׁהּ בְּאֶרֶץ יִשְׂרָאֵל, נוֹתֵן לָהּ מִמְּעוֹת אֶרֶץ יִשְׂרָאֵל. נָשָׂא אִשָּׁה בְאֶרֶץ יִשְׂרָאֵל וְגֵרְשָׁהּ בְּקַפּוֹטְקִיָּא, נוֹתֵן לָהּ מִמְּעוֹת אֶרֶץ יִשְׂרָאֵל. נָשָׂא אִשָּׁה בְקַפּוֹטְקִיָּא וְגֵרְשָׁהּ בְּאֶרֶץ יִשְׂרָאֵל, נוֹתֵן לָהּ מִמְּעוֹת אֶרֶץ יִשְׂרָאֵל. רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר, נוֹתֵן לָהּ מִמְּעוֹת קַפּוֹטְקִיָּא. נָשָׂא אִשָּׁה בְקַפּוֹטְקִיָּא וְגֵרְשָׁהּ בְּקַפּוֹטְקִיָּא, נוֹתֵן לָהּ מִמְּעוֹת קַפּוֹטְקִיָּא:
All are brought up to Eretz Yisrael, and none are taken out. All are brought up to Jerusalem [A man may compel all the members of his household to go up with him to Jerusalem. Even if he bought a Hebrew man-servant, he must, perforce, go up with him, even from a good abode to a bad one, and even from a city with a majority of Jews to one with a majority of idolators], and none are taken out, neither men nor women. [If he wishes to go up, and she refuses, she is divorced without a kethubah. And if she wishes to go up, and he refuses, he divorces her and gives her her kethubah.] If he married a woman in Eretz Yisrael and divorced her in Kaputkia, he gives her Eretz Yisrael currency. If he married a woman in Kaputkia and divorced her in Eretz Yisrael, he gives her Eretz Yisrael currency. R. Shimon b. Gamliel says: He gives her Kaputkia currency. [Kaputkia is Crete. Its coins are larger and heavier than those of Eretz Yisrael. And because a woman's kethubah is an ordinance of the scribes, they were lenient, allowing it to be paid with the lesser currency. And R. Shimon b. Gamliel holds that a woman's kethubah is Torah-ordained, for which reason he takes the more stringent view. The halachah is not in accordance with him.] If he married a woman in Kaputkia and divorced her in Kaputkia, he gives her Kaputkia currency.
