I am resident in spain and I have entered into a serious relationship with somebody from the UK and she has 2 young children. We are not thinking too far into the future yet and we are aware of the 90 day rule but it does beg the question.

How does it work if we want to be together permanently ?

Thank you.

If you get married she can join you here as a family member. You may have to prove that you have sufficient income to support your new family etc

"How does it work if we want to be together permanently ?"
Option B, you move back to UK.

Unless your (new) relationship started before the end of the transition period (31st December 2020), your new partner and her children cannot gain residency under the withdrawal agreement (i.e. as family members of someone protected under the WA) and will need to qualify in their own right, such as NLV. The only circumstance in which a new family member can qualify is if he or she is a new-born or newly-adopted child of an existing relationship predating the end of the transition period.

"Only"? ... If CBT has citizenship of an EU country, or takes Spanish citizenship, then he could sponsor his spouse/ partner and her dependent children.

Yes, of course. Similarly if his new lady can get Irish passport etc. But I was arguing on the basis of OP being a British citizen living in Spain under the WA.

Hmmmm I am eligible for an Irish passport but how does that effect my residency which was gained under my British passport.

If you are eligible for an Irish passport, why on earth have you got a British passport if you live in an EU state? I made sure I obtained my Irish passport before the end of the transition period and I'm extremely glad I did.

If you get the Irish passport, you can get your partner and children into Spain immediately. You can simply reapply for normal EU type residency with the Irish passport and you don't need to faff about with the ridiculous Brexit related stuff.

Can you get the Irish passport immediately or have you got to go via the FBR?

What is the FBR ? I did my residency with my british passport so just never felt the need to apply for my irish one. Surely if i was to get an irish one i wouldn't need to do my residency again ? Not like you have to forfeit the British one as you can have dual citizenship.

This make the most sense to be honest.

As a resident of this country you should be free to meet anybody from anywhere in the world.

So as a british citizen resident in spain i am only limited to finding love within the european union after brexit ?

Ridiculous answer

Visados Nacionales - Visado de reagrupación familiar en régimen general

Visado para familiares de los extranjeros que ya tengan residencia legal en España y que quieran ejercer el derecho a la reagrupación familiar.

You'll have to get married first since you won't be able to live together as a pareja de hecho due to the 90/180 rule.

To be more accurate Spain does not 'disallow' dual citizenship, rather it does not recognise it unless between countries with which it has agreements, UK not being amongst them.

You cannot be asked or told to surrender your UK passport either as it's the property of the UK government and cannot legally be taken from you by Spain.

In short, even if you take up Spanish citizenship you remain a UK citizen also. Renouncing that, were you to wish to do so, can only be done with the UK.

I suppose I'll just have to marry her then
