Yes.

If so, what are they? Are these only notarial acts or also acts of other authorities?

Such documents are considered as official written evidence and have greater probative value. The circumstances indicated in the official written evidence are considered fully proven, until they are denied of other evidence, other than testimony of witnesses.

The examples of such documents could be: wills, matrimonial agreements, real estate transactions, agreements of spouses regarding division of joint property, declaration on paternity recognition (when a child is born to an unmarried couple), lasting power of attorney, power of attorney, etc.

These authentic instruments are mostly notarial acts but some kind of acts can be issued by other authorities, for example, bailiffs (the inventory of assets, Statement of Factual Circumstances).

• The date on which the authentic instrument was drawn up
• The place where the authentic instrument was drawn up
• The signature by the parties of the authentic instrument
• The parties’ declarations
• Any observation made by the authority within the limits of its competence
• The measures the authority declares to have taken
• Appearance, identification and consent of the parties
