What does it mean when you claim "fraud"? Fox News said that they are going to ask for an annulment. That's usually because someone misrepresented him (her)self and was impotent, not really interested in having children, was substance-addicted and didn't tell the partner, etc. I assume that this wasn't financially-based as surely these people didn't marry without a pre-nup.
But if SHE is doing the separating, I wonder what HIS fraud.....
