One of the most common misconceptions about powers of attorney is that signing one locks you in. It does not. As the principal, you retain the right to revoke your POA at any time, for any reason, as long as you still have legal capacity to make that decision.
How to revoke a power of attorney in New Mexico
Revocation should be in writing. A signed, dated revocation notice is the clearest way to formally end your agent's authority. That notice should be delivered to:
-
Your agent, directly
-
Any bank, financial institution, or other third party that has been relying on the POA
-
Your healthcare providers, if revoking a medical POA
Some people revoke a prior POA by executing a new one that explicitly states it supersedes all previous powers of attorney. This is a common and straightforward approach, but it only fully protects you if the new document is delivered to everyone who had the old one.
What happens if your agent doesn't know about the revocation?
Under New Mexico law, an agent who acts in good faith without knowledge of a revocation is generally protected from liability. That protection, however, does not undo the transactions they completed. This is why prompt, documented notification matters.
When revocation happens automatically
In some situations, a POA may be revoked by operation of law without any action on your part. Divorce is one example: under New Mexico law, a POA granted to a spouse is typically revoked automatically upon divorce or legal separation, unless the document states otherwise. The death of the principal also terminates the POA immediately.
If your life circumstances have changed, including a divorce, a falling out with your named agent, or simply a change of heart, reviewing and updating your power of attorney is a straightforward process with an estate planning attorney.
