Not submitting signatures to qualified validation is a very serious mistake. It presupposes taking a risk that can cause incalculable damage by accepting signatures that will prove their deficiency at the worst possible moment, in a court of law.
The electronic signature of documents is a reality with which many entities and professionals are already familiar. However, it is not so common for these entities that make use of electronic signatures to follow the appropriate verification processes to ensure that the documentation received has been correctly signed and has some kind of legal effectiveness.
The consequences? Accepting documentation that, in practice, is not signed.
