Kesuvos4: 12
,,אַתְּ תְּהֵא יָתְבָא בְּבֵיתִי וּמִתַּזְנָא מִנִּכְסַי כָּל יְמֵי מִגַּד אַלְמְנוּתִיךְ בְּבֵיתִי” — חַיָּב, שֶׁהוּא תְנַאי בֵּית דִּין. כָּךְ הָיוּ אַנְשֵׁי יְרוּשָׁלַיִם כּוֹתְבִין. אַנְשֵׁי גָלִיל הָיוּ כוֹתְבִין כְּאַנְשֵׁי יְרוּשָׁלַיִם. אַנְשֵׁי יְהוּדָה הָיוּ כוֹתְבִין: ,,עַד שֶׁיִּרְצוּ הַיּוֹרְשִׁין לִתֵּן לִיךְ כְּתֻבְּתִיךְ”. לְפִיכָךְ, אִם רָצוּ הַיּוֹרְשִׁין — נוֹתְנִין לָהּ כְּתֻבָּתָהּ וּפוֹטְרִין אוֹתָהּ.
[If he did not write:] “You shall live in my house and be supported from my property all the days of the duration of your widowhood in my house,” he is [nevertheless] liable, since it is a condition established by the court. In this manner, the people of Jerusalem used to write. The people of Galilee used to write like the people of Jerusalem. The people of Judea used to write: “until the heirs wish to give you your kesubah.” Therefore, if the heirs so desired, they may give her her kesubah and dismiss her.
