I had two couples come to me.
They had been friends for nigh on 15 years.
Husband A decided he liked Wife B more than Wife A. Wife A decided she likes Husband B more than Husband A.
The reverse was also true, and Husband B preferred Wife A, Wife B preferred Husband A.
The couples had near identical assets in terms of value. They came to me all together, and I drafted two sets of paperwork. Two default judgment hearings were set on the same day. The judge signed all the papers the same day.
A week after that, they all went to a JP and remarried. The husbands swapped houses and they all went about their lives exactly as they had the week before, but each slightly happier.
