Nedarim10: 2
מֵת הָאָב — לֹא נִתְרוֹקְנָה רְשׁוּת לַבַּעַל. מֵת הַבַּעַל — נִתְרוֹקְנָה רְשׁוּת לָאָב. בָּזֶה יָפֶה כֹּחַ הָאָב מִכֹּחַ הַבָּעַל.  בְּדָבָר אַחֵר יָפֶה כֹּחַ הַבַּעַל מִכֹּחַ הָאָב, שֶׁהַבַּעַל מֵפֵר בְּבֶגֶר, וְהָאָב אֵינוֹ מֵפֵר בְּבֶגֶר.
If the father dies, the [sole] right does not fall to the husband. If the husband dies, the [sole] right falls to the father. In this matter, the power of the father surpasses that of the husband.  In another matter, the power of the husband surpasses that of the father, for a husband can revoke [his wife's nedarim] even after she has been a bogeres, while the father cannot revoke her nedarim once she becomes a bogeres.
Nedarim10: 3
נָדְרָה וְהִיא אֲרוּסָה, נִתְגָּרְשָׁה בּוֹ בַיּוֹם, נִתְאָרְסָה בּוֹ בַיּוֹם, אֲפִלּוּ לְמֵאָה — אָבִיהָ וּבַעְלָהּ הָאַחֲרוֹן מְפִירִין נְדָרֶיהָ. זֶה הַכְּלָל: כָּל שֶׁלֹּא יָצָאת לִרְשׁוּת עַצְמָהּ שָׁעָה אַחַת — אָבִיהָ וּבַעְלָה הָאַחֲרוֹן מְפִירִין נְדָרֶיהָ.
If she vowed while she was betrothed, [and] was divorced on the same day [and] betrothed [again] that same day, even to a hundred [men] —- her father and her current husband revoke her nedarim.  This is the general rule: As long as she had never entered into a state of independence for even one hour, her father and her current husband revoke her nedarim.
