I know I always heard that divorces are expensive, but you hear that about weddings too, don't you?
It cost us £110 and ten minutes to get married, I assumed that a (hypothetical as yet) divorce would be the same kind of thing if we were both ok with it. DH just signed a form and posted it back to his ex for his first divorce (they were separated, but as soon as he got a new girlfriend - me - she divorced him for adultery. Can't blame her one bit for wanting to be rid of him asap.)
I know, it was my own fault, but shouldn't you get some kind of leaflet before you get married? Maybe not about divorce, that would kill the mood, but about the legal implications? I looked them up myself, but I doubt most people do. All we got was a throwaway comment about reregistering the kids to legitimise them, which we of course ignored.
