all info please

Assuming you are British ...

The new rules are 90 days in any rolling 180.

So, after 90 days, you must leave the EU/Schengen zone (no popping off to Portugal or Gibraltar for a few days). 

You can't re-enter the EU for another 90 days.

Hi Many thanks for that.WOW that is an eye opener. there we were thinking pop into Portugal for a week!!!

So tell me please what are the rules on obtaining residencia

Mac

Again ... assuming you are Bitish ...

"Residencia" acquired a whole new level of bureaucracy and cost on 1.1.21.

For "Residencia", now read "Visa".

I won't bore you with the gory details, but the headlines ...

You/your partner need to demonstrate (between you) 33k Euros of available income/funding in year 1. Then 66K Euros of available income/funding twice more before your visa becomes permanent after 5 years.

You need criminal records checks. You need health checks.

If you are below UK retirement age, you need private healthcare (we are in our early 60s and we pay 2k Euros/year between us).

I'm not sure, now, if you will qualify for Spanish NHS at age 66, but you will qualify after 5 years of Residency.

You lose all but emergency access to the British NHS.

You have to switch to a Spanish driving licence (possibly a new test).

If you leave Spain for >6 months in a year, you lose everything that you have paid for - your visa becomes null and void.

The thread below goes on a bit, but contains good info. 

Spanish Consulate Update - application and income requirements, post Brexit - confirmation, Non-Lucrative Visa.

PS ... if you are well-set financially, you will very probably pay higher income tax in Spain.

Hotel is still closed. Golf course is open. Lots of places to rent. Good luck now getting residencia.
