1) Dayan Gelley Shlita is NOT Av Beis Din, his title is Senior Dayan.
2) London Beth Din Is NOT the only authority to register marriages and divorces. The UOHC also register marriages, and in fact the vast majority of ‘chareidi’ weddings are under their auspices. The London Beth Din are the only ones to register conversions.
