California is a no-fault divorce state. This means that no grounds need to be stated by either spouse to obtain a divorce. Instead, a dissolution of marriage can be granted due to an irrevocable breakdown of the marriage. There are residency requirements to divorce in California. At least one of the spouses needs to be a state resident for at least six months before filing the divorce petition. They must also reside in the county where they file for the divorce for at least three months prior to filing.
