Wedding Invitations

My fiancé is a lawyer. May he use esquire?

“Esquire” is a title to designate status and it is an honor that is
bestowed on him by others addressing him, but would be presumptuous to
put that designation upon himself in a formal wedding invitation. It just would
not be proper. It is not recognized as proper on a social invitation.

Everyone knows my fiancé by his nickname rather than is real name. Can we add his nickname in parentheses?

Not if you want your wedding invitations to be done properly. His name should read as it is on his birth certificate. We have done this on occasion at a bride’s request, but it really is not proper. Everyone will understand the formality expected of a formal wedding invitation. Surely they will know who the groom is by his last name and your name.
