Question:
Although it is the minhog not to say Baruch HaShem l’Olam Amen veAmen in Maariv said in Eretz Yisrael, should it be said or not said in the following circumstances: a maariv is said during a wedding in Eretz Yisrael, where the location is not a shul, and therefore there is no locational minhog aside from any general minhog Eretz Yisroel, and all participants are from Chutz Lo’oretz and normally say Baruch HaShem l’Olam Amen veAmen?
Answer:
The minyan should say Baruch Hashem Laolam.
