I know that high-profile marriages between followers of different Hasidic courts occur -- such as the Belzer Rebbe, Rabbi Yissachar Dov Rokach and one of the Satmar Rebbes, Rabbi Aharon Teitelbaum each marrying a daughter of Rabbi Moshe Yehoshua Hager, the Vizhnitz Rebbe.
My questions is: When this does happen is there a general rule that has been published by Hasidic Rebbes/Ravs that the woman follows the Hasidic traditions of her husband's Hasidic court?
