I'm not married or anything, but I was reading about this topic. Apparently a person must state the reason they want a divorce at a divorce trial and be able to prove that this reason is well-founded (in the US)
In a Fault divorce (something really "bad" happened), there most be no mutual consent. But, for a Non-Fault divorse, both parties have to agree on the divorce.
I find it uncanny, that you can't decide to undergo through a divorce on your own without having to prove anything. If you want out, you should be able to leave.
Maybe I interpreted the legal aspects wrong? If so, please correct me. I just read a little bit about the topic because of a random burst of interest.
What are your opinions about this?
