2. Can you indicate which are the most common authentic instruments in the case of a succession to the estates of deceased persons and which authorities issue them?

The will.
The choice of law applicable to the succession.
Acceptance or waiver of the succession, revocation of a waiver of a succession.
Winding up (liquidation) of the matrimonial regime.
Sharing out of the estate of the deceased.

These authentic instruments are issued by the civil law notary, although in certain cases the authentic form is not required by the law (e.g., the will, the acceptance of the succession).

Lastly, we mention that the civil law notary who settles a succession has the competence to issue a specific instrument: the certificate of inheritance. For details, please refer to Question 3 below.
