If you are a client of the office and have a case code, you can check the progress of your matter here.
You can try the system with the sample code ejemplo.
This system works through an individual, non-guessable code given directly to each client by the office. It does not replace the official services of the Spanish General Council of Notaries (Portal Notarial del Ciudadano) for consulting already-signed deeds; it is only for tracking the progress of ongoing matters at this office.
