Interesting post someone put up last year about the best and worst states to get a divorce. Not too surprisingly California ranked #47 on the list (as in 3rd from the worst state).
Doing some research on the site it appears they are basing this only on the cost of the divorce filing, the amount of residency required in that State, and the amount of time that must pass by before the divorce can become finalized. In this case California is expensive, requires a 6 month cooling off period, and the residency requirement is fairly strict. The good news though is California is a no fault divorce state. This means when it comes to spousal support or child support the reasons for the divorce should not come into play. Most family law courts will use a formula for determining these payments.
