12 Ketubot 4/10-12

(י) לֹא כָתַב לָהּ, בְּנִין דִּכְרִין דְּיֶהֱווֹן לִיכִי מִנַּאי אִנּוּן יִרְתוּן כְּסַף כְּתֻבְּתִיךְ יָתֵר עַל חוּלְקֵיהוֹן דְּעִם אֲחוּהוֹן, חַיָּב שֶׁהוּא תְנַאי בֵּית דִּין:

(יא) בְּנָן נֻקְבִין דְּיֶהֶוְיָן לִיכִי מִנַּאי, יֶהֶוְיָן יָתְבָן בְּבֵיתִי וּמִתְּזָנָן מִנִּכְסַי עַד דְּתִנַּסְּבָן לְגֻבְרִין, חַיָּב, שֶׁהוּא תְנַאי בֵּית דִּין:

(יב) אַתְּ תְּהֵא יָתְבָא בְּבֵיתִי וּמִתְּזָנָא מִנִּכְסַי, כָּל יְמֵי מִגַּד אַלְמְנוּתִיךְ בְּבֵיתִי, חַיָּב, שֶׁהוּא תְנַאי בֵּית דִּין. כָּךְ הָיוּ אַנְשֵׁי יְרוּשָׁלַיִם כּוֹתְבִין. אַנְשֵׁי גָלִיל הָיוּ כוֹתְבִין כְּאַנְשֵׁי יְרוּשָׁלָיִם. אַנְשֵׁי יְהוּדָה הָיוּ כוֹתְבִין, עַד שֶׁיִּרְצוּ הַיּוֹרְשִׁים לִתֵּן לִיךְ כְּתֻבְּתִיךְ. לְפִיכָךְ אִם רָצוּ הַיּוֹרְשִׁין, נוֹתְנִין לָהּ כְּתֻבָּתָהּ וּפוֹטְרִין אוֹתָהּ:

(10) If he did not write [in her ketubah], "The male children that you will have with me shall inherit the amount of your ketubah over and above their equal shares [of inheritance] with their brethren," he is, [nonetheless], obligated [in that condition], as that is a [fixed] stipulation [enacted] by the court.

(11) If he did not write [in her ketubah], "The female children that you will have with me shall live in my house, and be fed out of my property, until they are betrothed by men," he is, [nonetheless] obligated, as that is a [fixed] stipulation [enacted] by the court.

(12) [If he did not write in her ketubah], "You shall live in my house, and be fed out of my property, as long as you remain a widow in my house," he is, [nonetheless], obligated is [nevertheless] in force, as that is a [fixed] stipulation [enacted] by the court. [The above] is what the men of Jerusalem would write [in their ketubot]. The men of the Galilee would write like the men of Jerusalem. [however,] the men of Judea would write "[You shall live in my house, and be fed out of my property] until the heirs want to give you [the amount of] your ketubah." Therefore, if the heirs want, they [may] give her [the amount of] her ketubah, and dismiss her.
