Reference for Ketubot 1:4
בְּתוּלָה אַלְמָנָה, גְּרוּשָׁה, וַחֲלוּצָה, מִן הַנִּשּׂוּאִין, כְּתֻבָּתָהּ מָנֶה, וְאֵין לָהֶן טַעֲנַת בְּתוּלִים. הַגִּיּוֹרֶת, וְהַשְּׁבוּיָה, וְהַשִּׁפְחָה, שֶׁנִּפְדּוּ, וְשֶׁנִּתְגַּיְּרוּ, וְשֶׁנִּשְׁתַּחְרְרוּ, יְתֵרוֹת עַל בְּנוֹת שָׁלֹשׁ שָׁנִים וְיוֹם אֶחָד, כְּתֻבָּתָן מָנֶה, וְאֵין לָהֶן טַעֲנַת בְּתוּלִין:
A virgin who was a widow or a divorcée or a chalutzah from the marriage [If she then remarried without any apprisal (of that fact)] — her kethubah is a manah [for she entered the chuppah in a status of non-virgin] — and she is not subject to a claim of virginity. A proselyte, and a captive, and a bondsmaid, who had been redeemed and divorced and freed (when they were) more than three years and one day — their kethubah is one manah, and they are not subject to a claim of virginity.
