Reasons for divorce vary from sexual imcompatibility to a personality clash - do you have any experience?
The experience I have with divorce is that both of my grandparents divorced relatively early. 
The laws seem to vary around the world on it, but in most cases you still need to go through a legal process.
I agree with the legal process. Usually, at least one of the parties has grievances or issues, so a legal attorney paired with a judge to make sure the whole procedure goes smoothly and fairly seems like a good idea. 
And then you have to deal with things like alimony, child custody, visitation, child support, property, and debt.
I believe that around 50% of marriages end in divorce, but I also don't hear about smooth divorces very often, so I think there is room for improvement in the system in place right now. 
Definitely - I feel bad for the stay at home moms that all of a sudden find themselves divorced.  Alimony helps after the divorce, but not a lot.
On the other end, the other spouse may be unfairly responsible for the stay at home spouses expensive lifestyle post-divorce. There is potential for abuse on both ends.
