אבן העזר קע״אEven HaEzer 171

Se’if 1א׳

מִי שֶׁהָיָה נָשׂוּי יְתוֹמָה קְטַנָּה שֶׁהִשִּׂיאוּהָ אָחִיהָ וְאִמָּהּ, שֶׁאֵין קִדּוּשֶׁיהָ רַק מִדְּרַבָּנָן, וְחֵרֶשֶׁת, וּמֵת, וְנָפְלוּ לִפְנֵי אָחִיו לְיִבּוּם, אֵין בִּיאַת אַחַת מֵהֶן פּוֹטֶרֶת צָרָתָהּ. וְכֵיצַד תַּקָּנָתָם, מְלַמְּדִין הַקְּטַנָּה שֶׁתְּמָאֵן בּוֹ, וְכוֹנֵס אֶת הַחֵרֶשֶׁת. וְאִם רָצָה לְגָרְשָׁהּ, כּוֹתֵב לָהּ גֵּט אַחַר שֶׁיָּבֹא עָלֶיהָ, וּמֻתֶּרֶת לְזָר:

A man who was married to an orphan of minor age (note: who was married off by her brother or mother, and whose marriage is valid by Rabbinical decree) and a deaf woman (whose marriage is also only valid by Rabbinical ruling) and he died, and the women have fallen to his brother for possible levirate marriage, consummation of levirate marriage with one of these (Rabbinically married) women does not free her co-wife from levirate bonds. What is their resolution? We instruct the minor to reject him (annul the marriage), and the brother marries the deaf woman. If he wants to divorce her, he writes a divorce after consummating the marriage, and she is then permitted to a stranger.

Se’if 2ב׳

הָיוּ שְׁתֵּיהֶן חֵרְשׁוֹת אוֹ קְטַנּוֹת, בִּיאַת אַחַת מֵהֶן פּוֹטֶרֶת צָרָתָהּ:

If both wives were deaf or both were minors, consummation of levirate marriage with one frees her co-wife [from levirate bonds].

Se’if 3ג׳

הָיְתָה אַחַת גְּדוֹלָה וְאַחַת קְטַנָּה, בִּיאַת גְּדוֹלָה אוֹ חֲלִיצָתָהּ פּוֹטֶרֶת הַקְּטַנָּה, וְאֵין בִּיאַת הַקְּטַנָּה פּוֹטֶרֶת אֶת הַגְּדוֹלָה:

If one wife was of majority age, and the other was a minor, consummation of levirate marriage or chalitza (ceremony severing the levirate bond) with the adult wife frees the minor [from levirate bond], but consummation of levirate marriage with the minor does not free the adult wife.
