How Do I Use a Power of Attorney?

Signing a power of attorney is only the first step. The harder question for most people comes later: when the moment arrives, how does the agent actually use it to get something done? Understanding how an agent acts and proves authority makes the difference between a document that works and one that gathers dust.

First, Confirm the Document Is in Effect

Before an agent does anything, the agent needs to know the document is actually in force. Under Washington law, a power of attorney is effective when executed unless the principal provided that it becomes effective at a future date or upon a future event or contingency. See RCW 11.125.090. If the document is immediate, the agent's authority already exists and the agent can act right away.

If the document was written to spring into effect upon a triggering event, most often the principal's incapacity, then the agent first has to establish that the event occurred. RCW 11.125.090 addresses this by allowing the principal to name someone to determine in writing that the event has happened, and, for incapacity, by allowing a physician or licensed psychologist who has personally examined the principal to make that written determination. An agent using a springing document should gather that written proof before approaching a bank or other institution, because no one will act on the document until the trigger is documented.

Acting in the Principal's Name

Once the document is in effect, the agent steps into the principal's shoes for the tasks the document covers. When an agent signs a check, sells a car, or manages an account, the agent is doing so on behalf of the principal, not personally. The agent should make that clear by signing in a form that shows the representative capacity, for example signing the principal's name and then noting that it is signed by the agent under a power of attorney.

This distinction protects both the agent and the principal. Washington law provides that an act performed by an agent under a power of attorney has the same effect, and binds the principal and the principal's successors, as if the principal had performed the act. See RCW 11.125.240. In plain terms, a proper act by the agent counts as the principal's own act. That is exactly why signing correctly and staying within the document's authority matters so much.

Proving Authority to Third Parties

The most common frustration agents face is not a legal problem at all. It is a practical one: convincing a bank, title company, or brokerage to accept the document. Institutions are cautious because they do not want to hand over money or property to someone whose authority has ended. Washington gives agents a direct way to overcome that caution.

Under RCW 11.125.190, a person asked to accept an acknowledged power of attorney may request, and rely upon without further investigation, an agent's certification given under penalty of perjury. In that certification, the agent confirms a set of important facts, including that the agent is the person named in the document, that to the agent's knowledge the principal is still alive, that all events necessary to make the document effective have occurred, that the agent does not know of any revocation or termination, and that the agent is acting in good faith. Because the third party is allowed to rely on this signed statement, the certification is often the key that unlocks a hesitant institution.

Washington even supplies an optional form for this purpose. RCW 11.125.430 sets out an Agent's Certification as to the Validity of Power of Attorney and Agent's Authority, which an agent can complete and sign under penalty of perjury. Using this form, or one substantially like it, gives the institution the assurance it needs while keeping the process orderly.

When an Institution Still Hesitates

Occasionally an institution drags its feet even after the agent provides a proper certification. Washington law limits that. A person generally must accept an acknowledged power of attorney, or request a certification or translation, within seven business days of presentation, and must accept it within five business days after receiving a requested certification, subject to certain exceptions. See RCW 11.125.200. The same section lists the narrow circumstances in which a person may refuse, and it exposes an institution that wrongfully refuses to a court order and to liability for reasonable attorneys' fees and costs. Knowing these rules exist can help an agent calmly work through resistance rather than giving up.

Staying Within the Lines

Using a power of attorney well is not only about proving authority. It is also about respecting its limits. An agent may only do what the document authorizes, and certain significant actions require an express grant that the document may or may not include. An agent who acts outside the document's scope risks personal liability and can undermine the very plan the principal built. When in doubt, an agent should read the document carefully and get guidance before acting.
