Structure Of A Beth Din

A functioning beth din normally sits with three dayanim rather than a single judge, a requirement drawn from Jewish law's general preference for a panel over any one person's individual judgment in matters of consequence, though the presiding dayan, often the most senior in scholarship or experience, typically directs proceedings and writes or approves the court's final ruling. Major Jewish communities maintain standing batei din, such as the London Beth Din long associated with the United Kingdom's Chief Rabbinate, that handle recurring categories of case: supervising conversions to Judaism, overseeing religious divorce through the writing and delivery of a get, certifying food and products as kosher, and arbitrating civil disputes that Jewish parties choose to bring before a religious rather than a secular court.

Because a dayan's rulings can have serious practical consequences for the people involved, particularly in divorce and conversion cases where an error can leave a person's marital or religious status genuinely uncertain under Jewish law, the additional ordination of yadin yadin, beyond the ordinary rabbinic semichah, is treated as a serious credential in its own right, and not every ordained rabbi pursues it or is recognized as qualified to sit as a dayan even where he has studied civil law extensively.
