You have to file in CA as long as you meet the residency requirement of 6 months , you can only file for divorce in the county you live in as long as you've lived there for at least 90 days . You cannot file for divorce until you meet all the residency requirements .
The courts will require you to make a " good faith " effort to locate your spouse before granting a " divorce by publication " .
