I would suggest getting a free consult with a lawyer.
Eta.. get a bunch. I weaseled a bunch of free legal advice out of mine
Or check to see if there is a legal aide hotline for your county. They can give out legal advice for free over the phone.
Typically, your WS would be required to maintain your insurance while you are going through the process, but not after you are divorced.
My state requires the working spouse continue to support a non working spouse until the divorce is final. But I am not in Cali.
