Yes.
If so, what are they? Are these only notarial acts or also acts of other authorities?
According to Article 369 of the Civil Code, the document shall only be authentic when the authority or public official that will sign the document is competent by reason of the subject matter and place and is not legally prevented from signing it.
However, the document drawn up by a public official exercising his or her functions shall be deemed to have been drawn up by a competent public office-holder.
These are therefore notarial instruments, but also instruments of the courts or civil registrars, etc.
Also, according also to article 371 of the Civil Code, the authentic instrument provides full proof of the facts they state as practiced by the respective public authority or official, as well as of the facts which are certified in them on the basis of the perceptions of the documentary body; the mere personal judgments of the documentary are only valid as elements subject to the free evaluation of the court.
