How to annul an incestuous marriage

This is easy. You don’t even technically have to do a thing. This type of marriage is void ab initio.  And what that means is this: it is ABSOLUTELY null and void on its face. It never happened, it shouldn’t happen, it can’t happen. So you may have had a ceremony and all that, but the law says that only you think you had a ceremony. What you had may have been a ceremony but it definitely wasn’t a marriage. This is true in EVERY state in the Union.  It’s almost like this was just a personal nightmare you had and then you woke up. You don’t have to do anything to annul this baby. This puppy was dead on arrival.
And it may be better not to even bring this to anyone’s attention, since, you may be opening yourself up to legal action and jail depending on the circumstances of your particular nightmare.
