Many (all?) American states have "no-fault" divorce. I most know about California law, but I believe many states have similar rules.

If there are no children, it is generally just a question of filing papers and waiting a period of time. (Don't know what the minimum is.) That's assuming both parties are agreeable. I don't know what happens if one party is contesting the divorce.

Divorces are No-fault in California

Do you know the most surprising thing about divorce? It doesn't actually kill you, like a bullet to the heart or a head-on car wreck. It should. When someone you've promised to cherish till death do you part says, "I never loved you," it should kill you instantly.
