A small note for Anglican clergy who read this blog.
Until very recently, when I led the "signing of the marriage registers" after a wedding, here is how I did it: 1. The groom signs 3 copies (the two marriage registers, and what will be their marriage certificate). 2. The bride signs 3 copies. 3. Witness 1, then Witness 2, sign all 3. 4. Lastly I sign both marriage registers, I sign the same box on the marriage certificate, and then I sign the declaration at the bottom of the marriage certificate.
