A California advance directive is a legal document that lets you outline your medical preferences if you become unable to speak for yourself. It combines a living will and a durable power of attorney for health care to guide your care team and loved ones.
This planning tool is designed to reduce confusion during stressful moments and ensure your values and treatment choices are respected. Understanding how it works can support confident decision-making for both you and your California health care agent.

Understanding California Advance Directive Rules
Legal validity and statutory requirements
California Health and Safety Code Sections 4600–4751 establish the rules for a valid advance directive. You must be an adult of sound mind, sign the form voluntarily, and have at least one qualifying witness or notary public complete the required signatures.
Designating your health care agent
Choosing a health care agent is a core step, because this person will interpret your wishes, consent to or refuse treatments, and communicate with providers. Select someone who knows your values, can stay calm under pressure, and will act in your best interests.
Clarifying Treatment Preferences
Common scenarios to address in a living will
Use your living will section to outline positions on cardiopulmonary resuscitation, mechanical ventilation, artificial nutrition and hydration, dialysis, antibiotics, and comfort-focused care near the end of life. Being specific helps reduce ambiguity for your agent and clinicians.
Implementing and Using Your Directive
Copies, storage, and sharing with providers
Distribute signed copies to your health care agent, alternate agent, primary care physician, hospital medical record, and any other relevant parties. Keep a accessible copy with your advance care planning materials and consider adding it to your California medical ID registry or electronic health records where permitted.

FAQ
Reader questions
Can a California advance directive be changed after it is signed?
Yes, you can update or revoke an advance directive at any time as long as you have capacity. You may create a new document, notify your health care agent and providers in writing, or safely destroy the previous form, and providers must honor your most recent valid version.
Do California providers always have to follow an advance directive?
Providers must follow a valid advance directive, but they can decline to participate for reasons such as conscience or unavailability, provided they transfer care to a willing clinician and document the process; emergency laws also ensure treatment continues when necessary.
Does having an advance directive in California affect eligibility for government benefits?
An advance directive is an advance care planning tool and does not affect eligibility for Medi-Cal, Medicare, or other government benefits; it focuses only on your medical treatment preferences and the authority of your designated agent.
How often should I review my California advance directive?
Review your advance directive every few years, after major life or health changes, or when you switch providers, to confirm that your agent and treatment instructions still match your current wishes.
