How to Revoke a Power of Attorney in New Mexico

You signed a power of attorney two years ago naming your brother as your agent. Since then, your relationship has deteriorated, you have caught him accessing your bank account for personal expenses, or you simply want to name someone else. The question is: can you cancel it?

Yes. A principal can revoke a power of attorney at any time in New Mexico, as long as they have the mental capacity to do so. But revoking it incorrectly — or incompletely — can leave the old agent with the ability to keep making transactions in your name.

Here is how to do it properly.

Step 1: Put the Revocation in Writing

Do not rely on verbal statements or destroying the physical document. Tearing up your copy of the POA does not revoke it — the agent, banks, and county clerks may have their own copies, and those remain legally valid until you provide written notice of revocation.

Draft a written revocation that includes:

• Your full legal name
• A clear statement that you revoke the power of attorney
• The name of the agent whose authority you are terminating
• The date the original POA was executed
• Your signature
• The current date

Step 2: Notarize the Revocation

Have your revocation notarized. While New Mexico law does not explicitly require notarization for a revocation, it provides the same presumption of genuineness that the original POA relied on — and institutions that received the notarized original will expect a notarized revocation.

Step 3: Record the Revocation With the County Clerk

This step is critical if the original POA was recorded with a county clerk for real estate purposes. Under NMSA 1978, Section 47-1-7, powers of attorney used for real property must be acknowledged and recorded. The same applies to their revocation.

If the original was recorded in Bernalillo County, the revocation must be recorded in Bernalillo County. If it was recorded in multiple counties, record the revocation in every county where the original appears.

Until the revocation is recorded, a title company or buyer relying on the county records has no way to know the POA has been cancelled. An unrecorded revocation for a recorded POA is a lawsuit waiting to happen.

Step 4: Notify Everyone

Send certified copies of the notarized revocation to:

• The former agent. They need to know their authority has been terminated. Certified mail with return receipt provides proof of delivery.
• Every financial institution that received the original POA. Banks, brokerages, insurance companies, credit unions — every entity where the agent was authorized to act.
• The successor agent (if one was named). They should know the document has been revoked, especially if you are executing a new POA with different terms.

Until third parties receive actual notice of the revocation, transactions the former agent makes in good faith may still be legally binding. The faster you notify everyone, the smaller this window of vulnerability.

Step 5: Execute a New POA (If Needed)

If you are revoking the old POA because you want a different agent or different terms, prepare and execute the new document immediately. A gap between revoking the old POA and signing a new one leaves you with no protection if you become incapacitated.

What If the Agent Refuses to Stop?

If a former agent continues to make transactions after receiving notice of revocation, their actions constitute unauthorized use and potentially financial exploitation. In New Mexico, you can:

• Report the conduct to the Adult Protective Services division of the Aging and Long-Term Services Department
• File a complaint with local law enforcement
• Petition the court for an injunction and damages

The agent's fiduciary duties under the Uniform Power of Attorney Act do not disappear just because the POA is revoked — they are accountable for every transaction they made while the POA was in effect, and liable for any unauthorized transactions made after revocation.
