Vehicles in Spain are subject to frequent police checks, and carrying documentation at all times is obligatory.

You must carry:

Driving Licence

The car’s Ficha Tecnica (showing the technical details of the car) or Log Book if UK registered

All your insurance documents – receipt, certificate of insurance (for UK vehicles) and Green Card.

By law, the documents in your vehicle should be the originals, but it is possible to photocopy them and then take them to your local police station and ask them to “compulsar” the documents, ie stamp them with an official stamp to verify that these are certified copies.
