What is the legalization of a signature and how does it differ from a notarial power?

The legalization of signature is a notarial act distinct from the power. In the legalization, the notary certifies only that a signature is authentic and belongs to the identified person, without creating any representation or authorization. The notary does not attest to the content of the document.

The notarial power, on the other hand, authorizes a person to act on behalf of another for one or several specific legal acts.

When is signature legalization needed?

  • Private documents that must be presented to organizations requiring notarial authentication
  • Contracts or assignments of rights that will be used abroad
  • Administrative applications that require a legalized signature

Signature legalization is faster and more economical than a public deed. It can be processed online with the signatory appearing via video call, as provided by Law 11/2023.

A good tip is to grant the power that you need to be carried out but not grant the attorney the authority to obtain copies of the power themselves. In this way, once the attorney performs the mandate entrusted to them, it will suffice to retrieve the copy of the power from them, leaving the attorney without said power, thereby avoiding the need to execute a deed of revocation in the future.
