Hatoras Nedorim

The custom is to make Hatoras Nedarim (Annulment of Vows) on Erev Rosh Hashanah.
This is done in groups with one person standing in front of three people while requesting release from his promises. The Rebbe will do Hatoras Nedarim after davening on Erev Rosh Hashanah with a group of 10 prominent dayanim (scholars) of the Belz community.
