Yes, a power of attorney can be revoked at any time by the grantor, unless it is irrevocable by agreement.
Revocation procedure:
- Grant a notarial deed of revocation before a notary
- Notify the revocation to the attorney (recommendable in a reliable manner: registered mail)
- If the power was used for registry inscription or was notified to third parties, it is also advisable to notify said third parties
Automatic extinction of the power: The power extinguishes without the need for revocation in the event of death, declaration of incapacity, or bankruptcy of the grantor or the attorney, unless it is a preventive power.
It is important to act quickly when you want to revoke a power to prevent the attorney from carrying out undesired acts before receiving the notification.
