CA is a community property state, so any debt made by *either* spouse during the marriage, is a marital debt that you are *both* liable for. I always took that to mean any debt made from the date of the marriage to the date of the divorce. However, at this website:
[url]http://www.cyberstation.net/~paralegal/calif.htm[/url]
it states, "Both spouses are responsible for the debts incurred by either spouse between the date you married and the date you
separated. In general, you are not liable for the debts of your spouse after the date of separation."
I'm not sure how you 'prove' the separation date though (other than, of course, actually filing for divorce or for a legal separation).
Regarding your joint accounts, you are still liable for those accounts (even after the separation date), since they're in both names. So, you might want to call the creditors to find out what they would require to freeze or even close the accounts. They may do that just based on your request (even without his permission). I'm sure they would require it writing though.
My disclaimer--I AM NOT AN ATTORNEY, and you really should talk to one
