Do Satmar hassidim follow the Mishnah Berurah? If this is not the case, what sefer or sefarim do they use?
The chassidim in communities i know, this means poskim and dayanim, who bishita don't view the mishna berurah as the posek achron rely upon the rav shulchan aruch. This is a general attitude, not limited to satmar.
I've been in a Yeshiva with Satmar guys. By Halacha Seder they learnt Mishnah Berira. Reb Leibel Willger isn't Satmar but he uses Mishnah Berira all the time!
