How to Prove You Are Resident in Spain After Brexit (2025 Update)

Even though the Brexit transition period ended several years ago, it remains important for British citizens in Spain to understand how to prove their legal residency status in 2025 — especially when dealing with authorities, accessing services, or crossing borders.

While many UK nationals successfully registered before the Brexit deadline, some may still need to show valid proof that they’ve been living in Spain legally since before the transition period ended. This guide explains which documents remain valid, what you need to show, and how to ensure you're fully covered.

Your rights under the Withdrawal Agreement

If you were officially resident in Spain before the Brexit deadline in 2020, your rights to live and work in the country continue to be protected under the Withdrawal Agreement. However, it's essential that you can prove your status if requested by Spanish authorities, especially at border checks or when accessing healthcare, social security, or municipal services.

Are old residency documents still valid in 2025?

Yes. If you still hold the older style green A4 certificate or green residency card, these documents continue to be valid proof of residency and your protected rights. There is no legal obligation to exchange them for the biometric TIE card, although doing so may make travel and administration easier.

How do I prove my legal residency in Spain today?

In addition to your residency card (TIE or green certificate), the following documents may help reinforce your legal status:

• Padrón certificate: This proves you are registered at your local town hall and is often used in administrative procedures.
• Rental agreement or mortgage: A dated, legal document showing your residence in Spain.
• Utility bills: In your name and address, showing ongoing occupancy.
• Employment or freelance registration: Work contracts, autonomo registration, tax filings, or social security contributions all support your residency status.
• Healthcare documentation: Registration with Spain's public healthcare system (INSS) or proof of valid private health insurance.

Explore private health insurance for expats in Spain if you need visa-compliant cover or documentation for TIE applications.

Missed your appointment back then? If you were unable to secure an extranjería appointment during the 2020 rush, keep any evidence of appointment attempts (screenshots, emails). These may still support your case if needed in future reviews.

Still unsure? You can also refer to the UK Ambassador’s reassurance to British nationals in Spain — which continues to be referenced by expat advisors and immigration experts.

Conclusion

If you were legally resident in Spain before Brexit, your rights are secure — but being able to prove them is essential. Whether you hold the TIE card or still use the green certificate, having backup documentation will help in any situation involving Spanish bureaucracy, healthcare, or international travel.
