Just for  your information:

Nowedays usually the notario will make the registration by the Registro and you will get a nota simple from the Registro with some stamps on it to confirm it is registered. The Registro has local offices at every comarque. There is a website where you can order a nota simple for a finca or lookup where the nearest Registro-office is:

If you click on "localizador" and fil in your town you get the nearest office.
