What are grounds for divorce in California?

In California, there are two grounds for divorce (also known as dissolution):

• Irreconcilable differences. You simply check this box on the dissolution petition and the court will grant your divorce.
• Incurable insanity (almost never used). Medical proof that one spouse was insane when the petition was filed-and remains incurably insane-is required.

In addition, you or your spouse must have lived in California for six months and in your county for three months before filing a petition to dissolve your marriage. There is no residency requirement for filing for legal separation.
