I took the liberty of looking up NC's laws (your profile says NC, smokymtngirl85?) -
and wow. A marriage where one person is impotent is void too. Interesting. Anyway, they criminalize bigamy, and adultery, and presenting yourself as married with a person to whom you are not legally married when obtaining a hotel room. But not much else about getting non-legally married.
Now I've got to go read Ohio's laws...
