When do you stop being a californian resident?

You stop being a California resident when you establish a permanent home in another state and demonstrate an intent to make that state your primary residence. This typically involves actions such as obtaining a new driver's license, registering to vote in the new state, and moving your personal belongings. Additionally, spending more than six months outside of California can contribute to the presumption of no longer being a resident. However, individual circumstances may vary, and legal advice may be necessary for specific situations.
