Does one need the above paperwork to reside in Fuerteventura.
If you want to reside in Fuerteventura for more than 90 days you need to apply for residency. There are lots of other things you need (NIE NUMBER etc), so I suggest you speak to a solicitor or seek advice from the Spanish Government websites or the UK Government.
It's far too complex to answer in a brief reply on this forum!!

Thanks for that, we already have NIE numbers but was unsure about the Certificado de Registro.
If you want one, try https://www.derecho.com/
It will cost 25/30 euros, for 24/5 hour electronic delivery.
