Short answer. Yes. The Civil Code lists the expiration of the period for which the agency was constituted as one of the ways agency is extinguished, separate from revocation. If you fixed a one-year term, the agent's authority ends when that year runs out on its own, without you needing to take any further action.

What the law says

Agency is extinguished: (1) By its revocation; (2) By the withdrawal of the agent; (3) By the death, civil interdiction, insanity or insolvency of the principal or of the agent; (4) By the dissolution of the firm or corporation which entrusted or accepted the agency; (5) By the accomplishment of the object or purpose of the agency; (6) By the expiration of the period for which the agency was constituted.

Expiration is its own ground, not a form of revocation

The law lists six distinct ways agency ends, and expiration of the agreed period is one of them, listed separately from revocation. That distinction matters: revocation is something the principal actively does. Expiration of a fixed term needs no action from anyone — it happens automatically once the period you set has run out, precisely because you already built the end date into the agency when you created it.

Why the agent's authority doesn't outlive the term

A power of attorney limited to one year is, by its own terms, an authority that only exists for that window. Once the year ends, there's nothing left for the agent to draw authority from — the grant itself was time-bound. You don't need to send a revocation letter, demand the document back, or take any other step, because the automatic extinguishment listed in the law does that work for you. Anything the agent purports to do in your name after the term lapses is no longer backed by valid authority from you.

The other automatic triggers worth knowing

Expiration sits alongside several other events that end agency without any formal act by the principal: the agent's own withdrawal, the death, civil interdiction, insanity or insolvency of either the principal or the agent, the dissolution of the firm or corporation that gave or accepted the agency, and the accomplishment of the agency's object or purpose once the task is done. All of these end the relationship on their own, the same way a fixed term does — revocation is just one path among six, not the only one.

The practical risk once the term lapses

Because expiration is automatic, the real-world risk after the term is up isn't about whether the agent's authority ended — it did — but about whether a third party dealing with the agent knows that. If you want a clean break, telling the people your agent regularly deals with that the term has lapsed avoids disputes over whether they could still rely on an apparent authority that, as between you and the agent, no longer exists.
