A Lieberman clause is a clause included in a ketubah, named after Talmudic scholar Saul Lieberman, that stipulates that divorce will be adjudicated by a modern Bet Din (rabbinic court) in order to prevent the problem of the agunah. In the 1950s the Conservative movement's Rabbinical Assembly worked on the agunah issue. Orthodox Judaism has rejected the Lieberman clause as a violation of Jewish law. As such, it is only accepted as binding and valid in non-Orthodox denominations of Judaism.
