The five decisions an AHCD lets you make in advance

1. Who decides for you. You name an agent (and a backup) to make health-care decisions if you cannot. This is the most important choice in the document.
2. End-of-life care. You can state your wishes about life-sustaining treatment if you have an incurable condition, are unconscious with no reasonable chance of recovery, or are otherwise near the end. You decide whether to prolong life or focus on comfort.
3. Pain relief. You can direct that pain relief be provided even if it might shorten life.
4. Organ donation. You can authorize donation, refuse it, or stay silent.
5. Funeral & remains. You can name who has authority over your body, burial, cremation, and disposition.

When the directive takes effect

By default, your agent’s authority begins only when your primary physician determines that you cannot make your own health-care decisions — for example, because you are unconscious, sedated, suffering severe dementia, or otherwise incapacitated. (Cal. Probate Code § 4682.)

You can change this default. Some clients choose to make the agent’s authority effective immediately (helpful for spouses managing each other’s appointments). Others keep it strictly springing — effective only on incapacity.

“Unless otherwise specified in a power of attorney for health care, the authority of an agent becomes effective only on a determination that the principal lacks capacity, and ceases to be effective on a determination that the principal has recovered capacity.”

— California Probate Code § 4682

Choosing your health-care agent

This is the single most important decision in the document. The agent will be making real-time choices in a hospital room while you cannot speak. Pick someone who is:

• Available. Lives nearby or can travel. Answers their phone.
• Willing. Has agreed to do this; understands the responsibility.
• Aligned with your wishes. Knows what you want and can advocate for it even under pressure from other family members.
• Decisive. Can make a call without endless second-guessing.

Common picks: a spouse (with an adult child as backup), an adult child, a sibling, or a close friend. A few people you cannot name as your agent: your treating physician, an employee of your health-care facility (unless related to you), or someone who has been convicted of elder abuse. (Cal. Probate Code § 4659.)

HIPAA authorization — the companion document

An AHCD lets your agent make decisions, but a separate HIPAA authorization lets them access your medical records to make informed decisions. Without it, hospitals routinely refuse to share information — even with the named agent — citing federal privacy law.

We include a HIPAA authorization with every AHCD we draft, naming the same agents.

AHCD vs. POLST — what is the difference?

Most people need an AHCD. People with serious diagnoses or significant frailty often need both.

How a California AHCD must be signed

California gives you two valid options under Cal. Probate Code § 4673:

1. Two witnesses. Both adults, neither one related to you, neither one your health-care agent, neither one a beneficiary in your estate, neither one a health-care provider treating you. Stricter than will witnessing.
2. Notarization. One notary, no witnesses required.

We use the notarized format because it removes any future question about witness eligibility.

Where to keep it — and who needs a copy

• Original. In a fireproof safe at home (not a safe deposit box, which may be hard to access in a crisis).
• Your agent & backup. Each should have a copy and know where the original is.
• Your primary care physician. They typically scan it into your medical record.
• Your local hospital. If you have a hospital you would go to, you can pre-register the directive.
• Your phone. A photo of the signed document is enough to start a conversation with first responders.

Frequently asked questions

• If I have a living will, do I still need an AHCD?

  In California, the AHCD is the living will plus the medical power of attorney plus organ donation plus disposition of remains, all in one. The standalone “living will” is an older form. The modern California document is the AHCD.

• Can my agent override my written wishes?

  No. The agent must follow any instructions you wrote in the document and, for matters you did not address, must act in accordance with your known values and preferences. If your written wishes are clear, the doctors follow them.

• What if I do not name an agent and become incapacitated?

  California has a default surrogate-decision-maker statute, but it produces less control than naming your own agent — and in family conflicts, hospitals may insist on a court-appointed conservator. Filing a conservatorship takes months and costs thousands of dollars. An AHCD prevents that.

• Can I change my AHCD?

  Yes, at any time, as long as you are competent. The easiest method is to sign a new one (which automatically revokes the old). Tell your agents and your physician.

• Does the AHCD cover mental-health treatment?

  Partially. Standard AHCDs cover most mental-health decisions, but psychiatric hospitalization and some specific psychiatric treatments have additional statutory rules. If mental-health planning is a priority, ask about a separate “Psychiatric Advance Directive.”
