Choosing the Right Power of Attorney for Financial and Healthcare Decisions

Many people sign a power of attorney form at their bank, or print one online, and assume the job is done. In California, you generally need separate documents to authorize someone to manage your finances and make medical decisions if you become unable to do so.

A financial power of attorney gives your agent authority over specified financial matters, while an advance health care directive allows you to appoint someone to make health care decisions. Choosing the right documents and agents is an important part of preparing for possible incapacity.

At the Law Offices of Gary R. Kershner, I help clients in Oakland and throughout the Bay Area put financial and health care powers of attorney in place as part of a coordinated incapacity plan. If you already have documents and aren’t sure they would hold up, contact me to schedule a free consultation and discuss whether they still meet your needs.

Why One Document Can’t Cover Both

California treats financial and medical authority under two separate bodies of law in the Probate Code. The Power of Attorney Law governs your property and finances, while the Health Care Decisions Law governs who can consent to or refuse treatment on your behalf. 

The result is a division of authority. Depending on the powers granted, your financial agent can pay your mortgage, manage investments, handle tax matters, and deal with insurers, but cannot make medical treatment decisions solely under a financial power of attorney.

Your health care agent can choose your doctors and accept or refuse treatment, including life-sustaining treatment, but has no authority over your accounts solely because of that appointment. A form from your bank may be narrower still, covering only accounts at that institution.

What Makes a Financial Power of Attorney Durable

A power of attorney is “durable” only if it says it continues after you lose capacity. Under California Probate Code section 4124, the document must include language such as “This power of attorney shall not be affected by subsequent incapacity of the principal.” Without durability language, the agent's authority generally ends if you become incapacitated.

The document must meet California's execution requirements, including being dated and signed by you and either acknowledged before a notary or signed by two qualified witnesses. Your agent cannot serve as a witness. Notarization is particularly important for powers of attorney involving real estate transactions that require recording.

Scope matters as much as form. California requires express authority before an agent can make gifts or create, modify, or revoke a trust. Certain trust funding transactions also require specific authorization. A broad, generic form may omit those powers, which can interfere with your estate planning arrangements.

Also, keep in mind that a financial agent's authority generally ends when you die. Your estate is then handled under applicable estate administration laws and documents, including any will or trust.

Immediate or Springing Authority

You can make a financial power of attorney effective immediately or have it “spring” into effect upon your incapacity. Springing authority sounds more protective, but your agent must first establish that the conditions specified in the document have been met. This may require medical documentation or another form of verification.

An immediately effective power of attorney avoids that delay but gives your agent authority while you still have capacity. Consider how much you trust your chosen agent and when you want that person to act.

Health care authority follows a different default. Unless your directive says otherwise, your health care agent's authority begins when your primary physician determines you can no longer make your own health care decisions. You can choose to make it effective immediately, although you retain the right to make your own decisions while you have capacity.

How California’s Advance Health Care Directive Works

The advance health care directive does two jobs: it appoints your health care agent and records your treatment wishes. Getting both right is central to the power of attorney planning I do for clients approaching retirement or managing a diagnosis.

California’s statutory form, found in Probate Code section 4701, has four parts: agent appointment, health care instructions, organ donation, and naming a primary physician. You don’t have to use that exact form, and the California Attorney General’s advance care planning resources explain that no specific form is required as long as the directive meets state requirements. 

Your agent must make decisions according to your written instructions and other wishes they know about. Specific instructions about pain management, life support, or where you want to receive care give your agent firmer ground if relatives disagree. 

Choosing Your Agents

You can name the same person for both roles or split them. The skills don’t always overlap. A good financial agent is organized, honest, and comfortable with records and deadlines. A good health care agent is reachable on short notice, willing to ask doctors hard questions, and prepared to follow your wishes even when they would choose differently. 

Name at least one alternate for each role in case your first choice can’t serve. California also limits who can act as your health care agent: your supervising health care provider, or an employee of the facility where you receive care, generally cannot serve unless they are related to you or a coworker. Whoever you choose, your agents owe you a fiduciary duty to act in your interest, not their own. 

Signing Details That Can Undo Your Planning

An advance health care directive must be signed and dated and either notarized or signed by two qualified witnesses. Witnesses cannot be your agent, your health care provider or that provider’s employee, or the operator or an employee of a residential or community care facility. At least one witness must be unrelated to you by blood, marriage, or adoption and not entitled to any part of your estate. 

One rule catches families off guard. If you are a patient in a skilled nursing facility, your directive is not effective unless a patient advocate or ombudsman signs as a witness, even if the document is also notarized. A directive signed hastily after an admission can fail on this point alone. 

Comprehensive Estate Planning Services in California

I graduated from Santa Clara University in 1986 with an MBA and a law degree and spent many years in business litigation. Helping clients solve problems was rewarding, but I kept seeing disputes that better planning could have prevented. That led me to focus my practice on estate planning, where I help people prepare for changes before they become emergencies. 

The part of this work I value most is getting to know the people I represent: their histories, their families, and what they want for the years ahead. Choosing who will manage your money and speak for you medically is a personal decision, and I take the time to understand your relationships and priorities before drafting documents that reflect them. 

I work with clients in Oakland, Berkeley, Alameda, Emeryville, Rockridge, Piedmont, Fruitvale, Fremont, San Jose, San Francisco, and beyond. As an Oakland elder law attorney, I can review documents you already have or prepare a durable financial power of attorney and advance health care directive that work together.
