This one may not play as difficult as my usual themeless, but I’m really not sure.  I was aiming for a smooth, open grid with relatively few 3-letter answers (6 in this case) and this is what emerged.

I’m inordinately pleased with the clue for 57 Across, though I don’t wish to presume anything about the relevant couple’s legal affairs.  Please enjoy and share!
