Yes, exactly the same legal value as a power of attorney granted in person.
The Notarial Law, reformed to allow remote notarial actions, establishes that the notary can authorize public documents by identifying the grantor via videoconference with the required technical guarantees.
The process is identical to the in-person one:
- The notary verifies the identity of the grantor through the DNI/NIE visualized by camera
- The notary reads the document in full
- The grantor gives their consent
- The notary attests to the signature and the content
The resulting document is a notarial public deed with full validity erga omnes, registrable in registers, accepted by banks, administrations, and courts.
