To file for a divorce in the state of California, there are a number of requirements that must be met and procedures that must be followed. First, one must have been a resident of California for the previous 6 months, and generally, needs to have resided in the county he/she files in for the previous 3 months.
The person filing for divorce submits a petition to dissolve the marriage to the county' superior court. He or she must then serve this petition and certain other papers to the other spouse. There is the possibility, at that point, of the divorce or the grounds of it being contested. But even if not contested, there is a 6-month waiting period before a divorce can be finalized. As to grounds of divorce in California, however, there are only two: irreconcilable differences that have destroyed the marriage beyond repair or clinical insanity of one of the other spouse.
In some instances, both spouses might file jointly for divorce. If so, and if there are no children under 18, no large debts or real estate involved, the marriage is not over 5 years old, and certain other criteria are met, an immediate "summary" divorce can be made that skips the 6-month waiting period. A wife getting divorced will also have the option of reverting her last name to that which it was before the marriage began
