Is there any requirement for the location of men and women when taking photos of marriage certificate?

Yes, the photographer will teach you how to do it when you go to take pictures. . . This is a cultural tradition, where women are on the right and men are on the left, because in ancient times, boys were preferred to girls, and the left was the largest. Nothing, just look at how the leaders arrange their seats. That's it. Now it's a tradition, but it's different in the west, because men are on the right and women are on the left.
