Converting a minor in an orthodox family
If a minor was converted by a Beis Din (court of law run by qualified Jewish judges of Jewish law, and according to the dictates of Jewish law) and was raised in an orthodox Jewish family until his Bar-Mitzvah, what should he be told at that time in order to complete his conversion process?

Answer: When he approaches Bar-Mitzvah age, he should be informed gently that he was converted as a child by a Beis Din, and he may protest that now at Bar-Mitzvah age. It is recommended however, to explain to him the great merit of being part of HaShem’s heritage. After the above procedure, when he performs even one Mitzvah after his Bar-Mitzvah, he is completely Jewish.
