For those who live in Spain full time, if you are a resident, and on the Padron, have your Residencia and are in the Spanish social security system then there will be little change for those people.
However, those people living here, and who are not Resident or Fiscally Resident in Spain as they have not really decided whether they live in Spain, or the UK, could have problems when Brexit happens. The British Consulate is advising everyone to be fully legal in Spain and this has been backed up by the Spanish representatives who were in attendance at these meetings.
We have seen in Spanish Solutions a substantial increase in those requiring Residencias now TIES and we are happy to advise what documentation is required.
