Do the bride and groom pray the Mincha service of Yom Kippur on the evening of the wedding canopy?

Greetings,

It is the Ashkenazic custom that the groom recites the full confession liturgy of Yom Kippur at the end of the Mincha Amidah on the evening of his wedding canopy (see Piskei Teshuvot, Even HaEzer, siman 61, footnote 9). Likewise, brides follow this custom (Shulchan HaEzer, siman 6, se'if 3). However, this custom is not found among Sephardim (Shu"t Yabia Omer, part 3, Even HaEzer 9).

Regards,

Hillel Meirs
