“She changed her name (with a kiddush and e/t), made sure e/o called her by her new name”
not so simple. Rav Fisher, ZT’L, of the Eidas Hareidas in Yerushalayim, gave me an extra name after my husband brought in a kvitel with our whole immediate family’s names. besides what was mentioned above, we had to get a new ketubah as well!!
