The basic function
A power of attorney is a legal document that authorizes another person (called your agent or attorney-in-fact) to act on your behalf in financial and legal matters. The scope can be broad, covering all of your financial affairs, or narrow, limited to a specific transaction or asset.
In the context of estate planning, a durable power of attorney is the most relevant type. “Durable” means the document remains effective even if you become incapacitated. A standard (non-durable) power of attorney terminates if you lose mental capacity, which makes it far less useful for planning purposes.
What a durable power of attorney covers
The powers granted depend on what the document specifically authorizes. California law allows a broadly drafted durable power of attorney to cover:
- Managing and signing contracts for bank accounts, investment accounts, and brokerage accounts
- Buying and selling real property on your behalf
- Filing taxes and managing tax matters
- Managing business interests you own
- Applying for government benefits, including Social Security and Medicare
- Making gifts to family members (if explicitly authorized)
- Paying bills, managing debt, and handling insurance matters
The document can be drafted to include some but not all of these powers. It can also include specific limitations, restrictions on when the agent can act, or requirements for multiple agents to agree before taking certain actions.
What it does not cover
A financial power of attorney does not authorize your agent to make healthcare decisions. California has a separate document for that: the advance health directive (or healthcare power of attorney). The two documents cover different domains, and you need both in a complete estate plan.
A power of attorney also does not allow your agent to make a new will or trust for you, change an existing one, or take actions after your death. At your death, the power of attorney terminates automatically and the trustee or executor takes over.

When it becomes important
A durable power of attorney is designed for situations where you are alive but unable to manage your own affairs: a medical crisis, a serious accident, a period of cognitive decline, or an extended international trip where you need someone to handle matters at home.
Without a durable power of attorney, your family has limited options if you lose capacity. They may need to petition the Superior Court for a conservatorship, which is a court-supervised arrangement that costs several thousand dollars, takes months to establish, and places ongoing reporting obligations on the conservator.
A conservatorship is appropriate in some circumstances, particularly if there is a dispute among family members about who should manage affairs. But for most families, a well-drafted durable power of attorney avoids the need for court involvement entirely.
The agent’s responsibilities
Your agent under a power of attorney has a fiduciary duty to act in your best interest. They must keep your funds separate from their own, keep records of transactions made on your behalf, and avoid conflicts of interest. California Probate Code 4232 sets out agent duties specifically.
Choosing the right agent is as important as having the document. The person needs to be trustworthy, financially competent, and ideally geographically accessible. Many people name a spouse or adult child, with a backup agent named in case the first becomes unavailable.
Naming a backup (or successor agent) is especially important because the document’s usefulness depends entirely on having someone ready to act if you cannot.
Springing vs. immediate authority
A durable power of attorney can be drafted to take effect immediately when you sign it, or to “spring” into effect only when a specific condition is met, typically a physician’s certification that you lack capacity.
Immediate authority is simpler and avoids potential disputes about whether the triggering condition has been met. It requires a higher level of trust in your agent, because they technically have the authority to act as soon as you sign. Most estate planning attorneys in San Diego recommend immediate authority with a trusted agent.
A springing power of attorney adds a procedural hurdle: the agent needs to obtain physician documentation before acting, which can delay action in an urgent situation.
How it works alongside a living trust
A funded living trust handles the management of trust assets without requiring a power of attorney, because the successor trustee provision in the trust document covers incapacity. But most people hold some assets outside their trust, whether by design or because they forgot to fund the trust fully.
A durable power of attorney covers the gap. It gives your agent authority over assets not in the trust, and it handles matters the trust cannot address, like filing taxes, managing business interests, or applying for benefits.
A complete estate plan includes both. For a full view of what the document package typically covers, see the estate planning service page.
Signing requirements in California
A power of attorney in California must be signed by the principal (you), witnessed by two adults who are not the named agent and who are not your heirs, and notarized. California Probate Code 4121 sets out the execution requirements.
An improperly executed power of attorney may be rejected by financial institutions, which defeats its purpose. Banks and title companies in San Diego occasionally require their own institutional forms in addition to a privately drafted document, so it is worth confirming with your financial institutions what they accept before you need to use the document.
The California State Bar at calbar.ca.gov can help you find a licensed attorney in San Diego County who can draft and properly execute a durable power of attorney.

Can I revoke a power of attorney after I sign it?
Yes, as long as you are mentally competent. You can revoke a power of attorney at any time by signing a written revocation and notifying your agent and any third parties (banks, financial institutions) who may have received a copy. If the revocation is not communicated to people who were relying on the document, they may continue to honor it.
What if my agent abuses the power of attorney?
An agent who misuses a power of attorney for personal gain can be held civilly liable for breach of fiduciary duty, and in cases of theft or fraud, criminally liable. California courts can order an agent to account for their actions and to repay misappropriated funds. This is why choosing a trustworthy agent is the most important decision in the process.
Does a power of attorney need to be recorded with San Diego County?
Generally, no. A power of attorney does not need to be recorded to be valid. If your agent needs to use the document to sell or transfer real property, however, they may need to record it with the county recorder’s office at that time, along with the deed, so that the title company can verify the agent’s authority.
