What is the purpose of the digital version of the DNI in the notarial environment?
The digital version of the DNI (known as the "Digital DNI"), which complements the traditional physical format, enables citizens to prove their identity using a mobile phone app, with full legal equivalence. This advancement is especially relevant in the field of deeds, as the notary requires reliable proof of the identity of the grantors before formalizing the legal transaction.
Identification of the grantors before the notary
When a person goes to a notary to sign a deed—for example, a deed of sale, a gift, or an acceptance of an inheritance—the notary must verify that the grantor is who they claim to be, has the necessary legal capacity, and is authorized to perform the act. Traditionally, this verification has been carried out by showing a physical ID. With the introduction of the Digital ID, this proof of identity can be provided through the app, maintaining the same standards of security and authenticity.
Terms and conditions for its implementation
The regulatory framework governing the Digital ID establishes an adaptation period for notaries and other entities that must accept this form of identification. During this period, notaries may continue to require physical ID. After this period, signing deeds using digital ID will be enabled. In this regard, it is expected that, starting on the planned date, citizens will be able to visit the notary and use only their Digital ID for identification and signing their deeds.
Advantages for granting deeds
The adoption of the Digital National Identity Document (DNI) for the formalization of deeds offers several advantages. First, it facilitates the identification of the grantors without the need to carry a physical card, promoting efficient management. Second, it allows for technological adaptation of the notary's office, which can integrate direct digital verification systems. Third, this option increases accessibility to notarial services, especially for citizens with limited mobility or who reside outside the place of execution, by facilitating remote preparatory procedures. Finally, it strengthens legal security by maintaining a high level of guarantee in the identification and traceability of the deed.
Practical considerations and recommendations for users
For the use of the Digital DNI to be effective in the execution of deeds, citizens must:
-
Have the digital version activated on your mobile phone and linked to your identity.
-
Verify that the selected notary is adapted to the digital verification system and accepts the method.
-
Keep your DNI electronic certificates up to date and comply with the required technical requirements.
-
It is important to note that during the transition period, the notary may still request a physical ID card if the technological adaptation has not been completed.
For its part, the notary office must ensure proper interconnection, implement digital verification protocols, and train staff in the new procedure.
The incorporation of the Digital National Identity Document (DNI) in the field of deeds represents a significant step toward modernizing notarial acts, without sacrificing the traditional guarantees of authenticity, legality, and security. Once the regulatory and technological adaptation period is complete, citizens will be able to identify themselves and sign deeds before a notary solely using their mobile device, which will mean greater convenience, speed, and accessibility in formalizing legal transactions.
