From: Rabbi Moshe Sofer
To: Rabbi Wolf
The Chasam Sofer advises against arranging a get in Güssing before consulting the two surviving former rabbis who may know why their predecessors avoided the practice, especially for a traveler not of the community. He qualifies the Noda BiYehudah's restriction, limiting it to cities where multiple rabbis deliberately refrained over many years, and provides detailed guidance on recording the city's dual names and identifying the nearby blocked river.
