אבן העזר מ״חEven HaEzer 48

Se’if 4ד׳

קִדַּשְׁתִּי אֶת בִּתֵּךְ, וְהִיא אוֹמֶרֶת: לֹא קִדַּשְׁתָּ אֶלָּא אוֹתִי, הוּא אָסוּר בִּקְרוֹבוֹת הַבַּת, וְהַבַּת מֻתֶּרֶת בִּקְרוֹבָיו; וּמֻתָּר בִּקְרוֹבוֹת הָאֵם, וְהָאֵם אֲסוּרָה עַל קְרוֹבָיו:

[One says:] I married your daughter. And she (the mother) says: you did not marry [her], rather you married me. He is prohibited in coming close to the daughter, and the daughter is allowed in coming close to him; and he is allowed in coming close to the mother, and the mother is prohibited regarding coming close to him.

Se’if 5ה׳

כָּל אֵלּוּ שֶׁטּוֹעֲנִין הַקִּדּוּשִׁין, כְּשֶׁטָּעַן הַטּוֹעֵן שֶׁהָיוּ שָׁם עֵדִים וְהָלְכוּ לָהֶם לִמְדִינָה אַחֶרֶת אוֹ מֵתוּ, אֲבָל אִם הוֹדוּ שֶׁהָיוּ הַקִּדּוּשִׁין בְּלֹא שְׁנֵי עֵדִים, אֵין כָּאן קִדּוּשִׁין:

All of these that claim marriage, are like the claim of a one who claims that there are witnesses there [at the scene of something], and they (judges) went to them (the witnesses) and to the state afterwards or they (the witnesses) died. But, if they rejoice that they were married [and there were not] two witnesses, there is not marriage here.
