Last Updated: 29/09/2026Categories: Legalisation News

Spain has recently approved an extraordinary regularisation process that could allow up to 500,000 undocumented migrants to obtain legal residence and permission to work. For many people already in Spain, the next few months will be about proving identity, family ties, clean criminal record, and eligibility. That proof often starts with documents.

If you are a UK expat in Spain or a foreign citizen who lived in the UK for the past 10 years, supporting a family member, or preparing a Spanish immigration or residence application, this matters for one simple reason: Spanish authorities are likely to scrutinise paperwork closely, and demand for properly legalised documents may rise. A missing Apostille or an incorrect sworn translation is one of the easiest ways to lose weeks in the Spanish bureaucracy and delay your visa process.

This guide focuses on the practical part: how to legalise UK documents for Spain, especially:

  • UK Birth Certificate
  • UK Marriage Certificate
  • UK ACRO Police Certificate
  • UK Medical Certificate
  • UK Degree Certificate

 

What Spain’s 2026 decree actually changes (and what it does not)

The Spanish government has announced an extraordinary regularisation route expected to open in April 2026 (with reporting indicating a limited application window). The application period is expected to begin shortly, likely in early April 2026, and close on 30th June 2026. Eligibility requirements are such as being in Spain before 31 December 2025, proving a minimum period of presence of at least 5 months, and having no criminal record in spain or in their country of origin.

Check the announcement at the Spanish Chamber of Commerce in the United Kingdom. 

What it does not change: Spain still expects credible documents. If your paperwork is UK-issued, Spanish authorities typically want it:

  1. Correctly issued,
  2. Apostilled (legalised), and
  3. Sworn translated into Spanish when required.

 

The legalisation basics for Spain: Apostille, not embassy stamps

Spain is a member of the Hague Apostille Convention 1961. In practice, this usually means an Apostille is enough for UK public documents, without further consular legalisation, provided the document is correctly prepared.

For UK documents, the Apostille is issued by the UK Foreign, Commonwealth and Development Office (FCDO) legalisation service.

Some documents might require Solicitor Certification or a Notary Public Certification.  If you are not sure whether your document needs certification before the Apostille, contact the experts at WLS. 

 

What is Spain’s 2026 extraordinary regularisation process?

Spain’s government has announced a one-off regularisation process designed to give eligible foreign nationals who are already in Spain a route to legal residence and work authorisation. Reporting indicates the policy is being implemented through a government decree and could cover up to 500,000 people, subject to eligibility checks such as proof of presence in Spain before a cut-off date and a clean criminal record. If you are preparing any Spanish immigration application, the safest approach is to assume Spanish authorities will be strict about documentation standards and request properly legalised and translated evidence.

 

Do I need an Apostille for Spain on UK documents?

In most cases, yes. If a Spanish authority asks for a UK-issued certificate (birth, marriage, police certificate, degree certificate and similar), they commonly require an Apostille to confirm the document is genuine and internationally recognised. The Apostille is the legalisation method used between Hague Convention countries, including the UK and Spain. Once your UK document is correctly Apostilled, it can usually be presented directly in Spain, and then translated into Spanish when needed.

 

Which UK documents are most commonly requested by Spanish authorities?

It depends on the procedure, individual’s circumstances and type of visa you are applying for, but the most common requests include:

  • Birth certificate (identity and family relationship evidence)
  • Marriage certificate (family applications, dependant visas, registration)
  • ACRO police certificate (background checks for visas and residency routes)
  • Medical certificate (certain long-stay visas and residence applications)
  • Degree certificate (if you indent to pursue further studies in Spain)
  • Proof of address, financial evidence, and other civil documents (often case-specific)

The key is not just having the document. It must be the right version, correctly legalised, and sworn translated in a format Spain accepts.

 

How do I legalise a UK birth certificate for Spain?

  1. Use the correct certificate: Spain typically expects an official UK-issued full birth certificate, not a scanned printout and the longer version (with parents details).
  2. Apostille the certificate: The Apostille is added by the UK legalisation authority (FCDO).
  3. Translate to Spanish if requested: Many Spanish processes require a sworn translation (traductor jurado) by sworn translator registered with the Spanish Ministry of Foreign Affairs.

WLS can handle the full flow: Apostille plus sworn translation by a qualified translator registered with the Spanish Ministry of Foreign Affairs for Spanish use.

How do I legalise a UK marriage certificate for Spain?

  1. Check you have an official marriage certificate (or order a replacement if needed via the GRO website).
  2. Apostille the original certificate
  3. Translate into Spanish if required for your application.

If you are applying as a couple or proving family status, this document is often a gatekeeper. If it is not Apostilled, it is commonly treated as “not valid for official use” abroad, even if it is perfectly valid in the UK.

How do I get an ACRO police certificate for Spain, and how do I legalise it?

An ACRO Police Certificate is typically requested for immigration and visa applications to show your criminal record status (or lack of one). The process usually looks like this:

  1. Apply for the ACRO Police Certificate (ACRO Online application, ID, photo).
  2. Wait for issuance, then check the certificate details match your passport.
  3. Apostille the ACRO certificate for Spain.
  4. Translate into Spanish if requested by your consulate, immigration office, or legal adviser.

How do I legalise a medical certificate for Spain?

For Spain, a medical certificate must usually be:

  • Signed by a registered doctor
  • Suitable for legalisation
  • Apostilled (the doctor signature must be registered with the FCDO)
  • Translated into Spanish if required

UK government guidance confirms medical certificates signed by a registered doctor can be legalised.

How do I legalise a degree certificate for Spain?

For Spain, a degree certificate must usually be:

  • Certified by a UK Notary Public or Solicitor after having verified the authenticity of the academic award with the issuing university.
  • Apostilled by the UK Foreign, Commonwealth and Development Office (FCDO), and
  • Translated into Spanish, if required.

Both Solicitor and Notary Public certifications are accepted, provided they explicitly confirm that the authenticity of the document has been verified directly with the issuing educational institution. Statements such as “This is a true copy” or “This is an original degree certificate” are not sufficient on their own. The recommended wording is: “I have verified the authenticity of this document with the issuing institution.” Once properly certified, the document can then be submitted to the UK Legalisation Office for the Hague Apostille.

Do I need to translate the Apostille into Spanish?

The UK Apostille is already issued in Spanish language in addition to English and French, however, sometimes lawyers in Spain request for the Apostille also to be translated, but this is not a requirement by the Spanish authorities.

Spain may require the underlying document to be translated, and in some cases the Apostille itself may also need to be included within the translated bundle. Requirements can vary depending on the authority (consulate, immigration office, court, local registry or lawyer).

If you want a safe approach: assume translation will be required unless the Spanish authority has confirmed otherwise in writing. WLS can arrange sworn translation as part of your Spain document pack.

 

How long does an Apostille take in the UK?

It depends on document type and service level. Some people use standard processing, while others choose faster options when deadlines are tight.

WLS is a registered FCDO provider that offers the Apostille Next-Day service. 

If your appointment with the Spanish authorities or submission date is already booked, do not leave it until the last minute. The reality is: the moment you discover a missing Apostille is usually the moment you are already late.

 

How long is an Apostille valid for Spain?

An Apostille does not usually “expire” on its own. However, the document underneath it can become time-sensitive. For example, police certificates and medical certificates are often only accepted if they are recent (usually, less than 6 months – but rules vary by process).

A practical rule: treat time-sensitive documents as having a short shelf life, and request your Apostille close enough to submission that Spain will accept it without questions.

 

The WLS “Spain Pack” checklist

Common rejection traps (and how to avoid them)

1) Sending the wrong version of the certificate

Some certificates must be official originals or official replacements. A scan or uncertified copy or documents containing electronic signatures often fails.

2) Name mismatches across documents

If your passport uses one format (middle names, accents, double surnames) and the certificate uses another, Spain may ask questions. Fix inconsistencies before legalising.

3) Notarising when you did not need to, or not notarising when you did

Some documents are public registry documents and can be Apostilled directly. Others need a notary or solicitor first. If in doubt, WLS can confirm the correct route.

4) Translating before Apostille

Often, the cleanest process is: get the document Apostilled first, then translate the final version. That way, your translated pack matches exactly what you submit.

Next step: get your documents Spain-ready before demand spikes

Whether Spain’s 2026 regularisation affects you directly or not, it is a clear signal that immigration admin is about to get busy. If you need to present UK documents to Spanish authorities, the best move is to prepare early and submit a clean, correctly legalised, correctly translated pack.

 

Spain Regularisation 2026 for Indians, Pakistanis, Moroccans and Other Growing Communities

Spain’s regularisation 2026 scheme is attracting strong interest from Indian nationals, Pakistani nationals and Bangladeshi nationals who want to secure legal residence in Spain. Many already live and work in Spain and now want stability, work authorisation and access to public services.

But South Asia is not the only region watching closely. Spain has historically received large numbers of migrants from Morocco, Colombia, Venezuela, Romania, Ecuador, Honduras, Peru and Senegal, alongside communities from Nigeria, Pakistan, China and India. Moroccan nationals consistently represent one of the largest foreign populations in Spain, and Latin American migration to Spain has increased significantly in recent years.

If you are part of any of these communities and hold UK-issued documents, your paperwork must usually be legalised correctly before being accepted by Spanish authorities.

That is why people search for Spain regularisation 2026 for Indians, Spain regularisation 2026 for Pakistanis, and Spain regularisation 2026 for Bangladeshis, and then quickly realise they need UK Apostille for Spain Spanish translation. In practical terms, that often means preparing a pack that includes a legalise UK birth certificate for Spain, a legalise UK marriage certificate for Spain, and, where requested, an ACRO police certificate Apostille for Spain and medical certificate Apostille for Spain.

WLS can help you organise the correct route for UK Apostille for Spain plus UK Apostille for Spain Spanish translation, so you can present a clean, compliant document pack rather than scrambling to fix rejected paperwork at the last minute.
