A symbolic Wedding Blessing ceremony compliments the legalities of a Marriage or a Civil Partnership Registration. Therefore you can incorporate your family and friends in a meaningful celebration of your special day.
Consequently, you can arrange this ceremony for the same day and make it part of the legal service. Alternatively it could be a couple of days or weeks apart depending if you wish to have two ceremonies.
The legal ceremony is just that, it’s just the exchanging of paperwork. A symbolic Wedding Blessing is looked upon as the “real day”. As a result, you can keep the exchanging of rings for this ceremony to enhance the day and make it even more special along with your ideas and / or scripted promises and vows.
