My recommendation, don't do it. The FTB will come find you. Unless you do it right of course. But that means principal residence in Az, vehicles in Az, company and/or taxes in Az. If you're still married and wife files taxes in Ca and you in Az, that will probably be an issue. Now if she doesn't work or does not file in Ca then you might be ok.

Ca is brutal at collecting. Can't wait to get the hell out
