Question: Is the chazan required to daven his silent Sh’moneh Esrei in the same nusach as the tzibur and with which he will use for Chazaras HaShatz?

 Short Answer: While the chazan must daven Chazaras HaShatz in the same nusach of the tzibur, many poskim allow him to daven his silent Sh’moneh Esrei in his own nusach. Rav Moshe Feinstein zt”l, however, required even the private Sh’moneh Esrei to be the same nusach as the tzibur.

Question: May a chazan start Chazaras HaShatz immediately after finishing his silent Sh’moneh Esrei?

 Short Answer: While some poskim rule that a chazan must pause for a few seconds before starting Chazaras HaShatz, many poskim rule that this is only a custom and not imperative. The chazan can likely rely on the lenient opinion where other factors, such as the embarrassment of the Rabbi (who has already finished his silent Sh’moneh Esrei), are in play.

Question: A man is saying Kaddish for a grandparent. Does he have the right to join the rotation of men serving as chazan, each in memory of a parent? Does it matter whether he is saying Kaddish for his maternal or paternal grandparent?
