Responsa Beit Yosef

As head of the court of Tzfat, Karo answered questions sent from across the Jewish world. One volume of his responsa, dealing with the laws of Even HaEzer — marriage, divorce and personal status — was published by his son, Rabbi Yehudah Karo, in Salonica in 1598. In its introduction the son mentions other works of his father that remained in manuscript.
