Divorce has traditionally been a fault-based proceeding, but California and most other states are now no-fault jurisdictions, and a divorce in legal terms is now called a Dissolution of Marriage.
And yet we never hear anyone say “I’m going to dissolve you.”
The primary ground for dissolution in California is “irreconcilable differences.” In a Regular Dissolution you are also allowed to use “incurable insanity.” Your spouse may seem crazy to you, but the insanity case is too complicated for you to present without an attorney, so if you want to keep things simple, go ahead and use “irreconcilable differences.”
