Se’if 1א׳

הַנּוֹשֵׂא אִשָּׁה, וּבָדְקָה עַצְמָהּ וְנִבְעֲלָה, וּבְעֵת שֶׁקִנְּחָה עַצְמָהּ הִיא וְהוּא נִמְצָא דָּם עַל עֵד (פֵּרוּשׁ, הַסְמַרְטוּט אוֹ מַטְלִית שֶׁבּוֹדֶקֶת עַצְמָהּ בָּהֶן) שֶׁלָּהּ אוֹ עַל עֵד שֶׁלּוֹ, אִם אֵרַע זֶה פַּעַם אַחַר פַּעַם שָׁלשׁ פְּעָמִים סְמוּכוֹת זוֹ לָזוֹ, הֲרֵי זוֹ אֲסוּרָה לֵישֵׁב עִם בַּעֲלָהּ, וְתֵצֵא בְּלֹא כְּתֻבָּה, לֹא עִקָּר וְלֹא תּוֹסֶפֶת, וְלֹא תְּנַאי מִתְּנָאֵי הַכְּתֻבָּה, שֶׁהֲרֵי אֵינָהּ רְאוּיָה לְתַשְׁמִישׁ; וְיוֹצִיא, וְלֹא יַחֲזִיר לְעוֹלָם. בַּמֶּה דְבָרִים אֲמוּרִים, כְּשֶׁהָיְתָה כָּךְ מִתְּחִלַּת נִשּׂוּאֶיהָ, וּמִבְּעִילָה רִאשׁוֹנָה רָאֲתָה דָּם. אֲבָל אִם אֵרַע לָהּ חֹלִי זֶה אַחַר שֶׁנִּשֵּׂאת, נִסְתַּחֲפָה (פֵּרוּשׁ, מִן "מַדּוּעַ נִסְחַף אַבִּירֶי ךְ" (יִרְמְיָהוּ מו, טו), כְּלוֹמַר נִפְסְדָה וְנֶאֶבְדָה לְמַזָּלְ ךְ) שָׂדֵהוּ. לְפִיכָךְ, אִם בָּעַל פַּעַם אַחַת וְלֹא מָצָא דָּם, וְאַחַר כָּךְ חָזְרָה לִהְיוֹת רוֹאָה דָּם בְּכָל עֵת תַּשְׁמִישׁ, יוֹצִיא וְיִתֵּן כְּתֻבָּה כֻּלָּהּ, וְלֹא יַחֲזִיר עוֹלָמִית. הַגָּה: יֵשׁ אוֹמְרִים דְּאִם אֵינוֹ רוֹצֶה לִשָּׂא אַחֶרֶת, וְרוֹצֶה לִשְׁרוֹת (עִם) זוֹ עַל יְדֵי שָׁלִישׁ בְּשָׁנָה אַחַת, וְלֹא יֵלֵךְ אֶצְלָהּ אֶלָּא בְּעֵדִים, אֵין צָרִיךְ לְגָרְשָׁהּ (בֵּית יוֹסֵף בְּשֵׁם תְּשׁוּבַת הָר"ם, וְכֵן הוּא בִּתְשׁוּבַת הָרַשְׁבָּ"א סִימָן תת"ס). וְכָל שֶׁכֵּן אִם זִנְּתָה תַּחְתָּיו, דִּמְאִיסָה לֵהּ, דְּשָׁרֵי בִּכְהַאי גַּוְנָא (שָׁם):

If a man marries a woman, she checked herself, and then had sexual relations, and afterward when she wiped herself and he [wiped himself] blood was found on the witness (Note: meaning the rag or cloth with which she checks herself) of hers or on his witness, and this occurred three consecutive times, she is forbidden to remain with her husband, and she is divorced without receiving ketuba monies, not the basic money nor the additional money, nor conditioned [moneys] from the conditions of the ketuba, for she is not capable of sexual relations. He divorces her and may never remarry her. What are the circumstances? When this occurs from the beginning of her marriage, and she saw blood with the first intercourse. But if this occurred afterward, then his field has been washed away (Note: meaning, from the verse, "why have your brave men been washed away," (Jeremiah 46:15), in other words, she has been damaged and lost by his bad luck). Therefore, if they had relations one time and did not find blood, and afterward she returned to seeing blood with every intercourse, he divorces her but must pay the entire ketuba, and may never remarry her. Note: Some authorities say that if he does not wish to marry another, and desires to stay with this woman at the hands (in the company) of a chaperone for one year, and he will not go to her except with witnesses, he is not required to divorce her (Beit Yosef in the name of Response Ram, and likewise in Responsa Rashba chapter 860). And certainly if she committed adultery, such that she becomes disgusting to him, it is permitted (to stay with her) in this manner (ibid.).

Se’if 2ב׳

אִשָּׁה שֶׁנִּבְדְּקָה עַל יְדֵי נָשִׁים, וְאָמְרוּ שֶׁאֵינָהּ רְאוּיָה לְאִישׁ, אֵין לָהּ כְּתֻבָּה וְלֹא תְּנָאֵי כְּתֻבָּה. וְאִם הַבַּעַל טוֹעֵן עָלֶיהָ כָּךְ, כָּל זְמַן שֶׁלֹּא נִבְדְּקָה אֵינוֹ חַיָּב בִּמְזוֹנוֹתֶיהָ:

A woman who was checked by other women, and they said that she is not fit for [relations with] a man, she has no ketubah nor the conditions of the ketubah. And if the husband argues this against her, he is not obligated in her sustenance all the time that she has not been checked.

Se’if 3ג׳

הַנּוֹשֵׂא אִשָּׁה, סְתָם, וְנִמְצְאוּ עָלֶיהָ נְדָרִים שֶׁנִּתְבָּאֲרוּ בְּסִימָן ל"ט, תֵּצֵא בְּלֹא כְּתֻבָּה, לֹא עִקָּר וְלֹא תּוֹסֶפֶת:

One who marries a woman stamp (without an explicit understanding) and finds that she is held to vows that are explained in siman 39 she leaves (the marriage) without (receiving payment) for her kesuba. Neither the mandated nor the extra (payment).
