[CA] Can someone create a medical power of attorney for another competent adult?

Lexi, Chatbot

I understand that setting up a medical power of attorney can be a significant decision. Have you already identified someone you would like to designate as your agent for medical decisions?

Are you looking to create this document for yourself or for someone else?

Hello and welcome to our service. My name is Queeneth. I am an attorney with over 8 years of legal experience. I will do my best to assist you today. First, I need to ask you a few questions to give you the best answer.

(Kindly note that our conversation does not establish an attorney-client relationship.)

Can you please tell me which state or country you and the person for whom you're creating the medical power of attorney are located in? Is the person for whom you're creating the POA currently able to understand and communicate their wishes (that is, do they have mental capacity)?

In California, what you’re looking for is usually an Advance Health Care Directive (AHCD) — it’s the standard California form that lets you name a health care agent (medical POA) and state your treatment wishes (optional but strongly recommended) (CA Prob Code § 4671). California has an official/recognized AHCD form you can use.

What you need to do a California medical POA (AHCD):

1) Information to gather

• Your full legal name, address, and date of birth
• Your agent’s full name, address, and phone/email
• At least one alternate agent (highly recommended)
• Any preferences about:
  • Life support / CPR / ventilator
  • Tube feeding
  • Pain relief
  • Organ donation
  • Burial/cremation preferences (optional)

2) The form
Use a California Advance Health Care Directive form. You can fill it out yourself (no lawyer required).

3) How to sign it (California execution rules)
California lets you make it valid either by:

Option A — Notary
Sign before a notary public.

Option B — Two adult witnesses
Two adults watch you sign and then they sign as witnesses.

Important restriction: At least one witness cannot be related to you by blood, marriage, or adoption and cannot benefit from your estate.

If you’re signing in a skilled nursing facility, California has extra witness requirements (a patient advocate/ombudsman).

(Using a notary is often simplest, especially if there’s any chance of disagreement later.)

To make sure it actually works in real life:

• Give a copy to your agent and any alternates
• Give a copy to your primary care doctor and any specialists
• Keep a copy where it’s easy to find (and tell your agent where)
• If you use a patient portal (Kaiser, Sutter, UCLA, etc.), upload it

Consider adding HIPAA access language. Most AHCD forms include language allowing your agent to access medical information. If your form doesn’t, include a HIPAA release so providers can talk to your agent immediately.

Don’t name someone who may be hard to reach or who you don’t fully trust under pressure.

Don’t keep it unsigned or unwitnessed — it won’t help you in an emergency.

Don’t assume “my spouse can decide” — hospitals often still ask for paperwork, especially with blended families or estrangement.
