Learn how apostilles, sworn translations, certificate validity and common document errors can delay immigration applications in Spain.
Spain's extraordinary regularisation process received 1,174,978 applications before the 30 June 2026 submission deadline, according to figures published by the Ministry of Inclusion, Social Security and Migration. Each application required documents from abroad, and many needed translation and authentication.
More broadly, Spain had more than 7.5 million foreign nationals with valid residence documentation at the end of 2025, representing a 4.5% increase over the previous year. As international mobility continues to shape the country's workforce and population, foreign document translation remains an important part of the immigration process.
However, obtaining these documents and certified translations is only part of the process. Applicants must also ensure that they meet the relevant authentication and translation requirements. An incorrect translation, or a missing apostille or certificate outside the accepted validity period, can lead to additional requests and delays in an immigration application.
Which foreign documents are commonly required for immigration procedures?
The documents a foreign national must provide depend on their nationality, purpose, and procedure they intend to follow.
Some of the most commonly requested foreign documents include:
-
Criminal record certificates
-
Birth certificates
-
Marriage certificates
-
Academic degrees and certificates
-
Civil status certificates and other registry documents
When these documents are written in a language other than Spanish, they may need to be accompanied by a translation that meets the requirements of the relevant administrative authority.
Apostille and translation: Which should come first?
Apostille and translation are two separate procedures and serve different purposes. The Apostille Convention (Hague Convention of 5 October 1961) lets certain public documents be used in other member countries without consular legalisation. It authenticates the origin of certain public documents so they can be used in another contracting country without going through the ordinary consular legalisation process.
An apostille certifies elements such as the authenticity of the signature, the capacity in which the person signing the document acted and, where applicable, the identity of the seal or stamp. It does not verify the truth of the document's contents or replace its translation.
If the issuing country is not a party to the Hague Convention, diplomatic legalisation may be required, unless an international agreement provides an exemption.
What is the correct order?
As a practical rule, it is advisable to complete the apostille or legalisation of the original document before arranging its translation. This allows the translator to include the document's contents, stamps, annotations and the apostille itself.
For example, if you translate a criminal record certificate and only then get it apostilled, you may need a second translation that covers the apostille.
This can mean extra time and costs that could have been avoided. Always check the receiving authority's instructions and the issuing country's specific requirements before starting the process.
Some documents are exempt from apostille or legalisation requirements under international agreements. Certain public documents issued by EU Member States are also exempt from these formalities in the areas covered by Regulation (EU) 2016/1191.
Common mistakes when translating foreign documents
A translation may appear linguistically correct and still contain errors that can lead to rejection. The following are some of the most common problems.
Errors in names and personal details
Differences in the spelling of names and surnames can raise questions about an applicant's identity.
For example, if your passport records your name as "Muhammad Ali", your birth certificate may use a different transliteration, such as "Mohamed Aly". The translator should faithfully reproduce the details in the original document without making arbitrary changes. Tell your translator how your name appears in your passport. Many sworn translators will note the passport spelling alongside the original.
If discrepancies exist between documents, you should check whether supporting documentation is needed to clarify them.
Omitted stamps, signatures and annotations
Official documents contain more than just their main text. They may also include institutional stamps, signatures, handwritten notes, verification codes and marginal annotations.
Suppose a criminal record certificate contains a note at the bottom stating that the document was issued for submission to a foreign authority. If the translation omits this information, the translated document will be incomplete.
This is why the professional handling the translation should review every page and all relevant elements of the original document.
Incorrect translation of legal and academic terminology
Some administrative terms have no exact equivalent across languages and legal systems.
Translating the name of a foreign university qualification word for word may produce a designation that does not correspond to its academic level in Spain. The translator should preserve the meaning of the original document without claiming an official equivalence not recognised by the competent authority.
Submitting a translation that does not meet official requirements
In Spain, translations produced by sworn translators-interpreters authorised by the Ministry of Foreign Affairs, European Union and Cooperation have official status. Translations from Spanish consulates abroad, or by the consulate in Spain of the applicant’s country, are recognised under Spanish regulations. They may also be accepted, including those produced by diplomatic and consular representations.
Before ordering a translation, you should confirm which type the authority handling your application accepts. A translation produced by a professional abroad is not automatically valid for every Spanish administrative procedure.
How long are foreign certificates valid?
No universal validity period applies to every foreign document. Acceptance depends on the nature of the certificate, the laws of the issuing country and the requirements of the procedure in which it is being submitted.
Criminal record certificates need extra care because they show only your record as of the issue date. For this reason, authorities may require them to have been issued within a specific period before you submit the application.
For example, if you obtained a criminal record certificate eight months ago, you should not assume that it will still be accepted. You need to check whether the procedure sets a maximum period from the issue date.
During Spain's 2026 extraordinary regularisation process, the Government required criminal record certificates from Spain, the applicant's country of origin and countries where the individual had lived during the five years before entering Spain, in accordance with the published requirements.
The supporting documentation also had to identify the applicant and include a date to be considered valid.
It is also important to distinguish between the validity of the document and that of its apostille. An apostille does not, by itself, extend the acceptance period of a certificate. If the document has a deadline for acceptance, legalisation does not change that deadline.
Therefore, before requesting a certificate, check the relevant authority's requirements and estimate how much time will pass between issuance, legalisation, translation, and submission.
How to prevent errors from delaying an immigration application
A preliminary review can help identify mistakes before the documents become part of an administrative file.
Here are some useful checks applicants should make:
-
Consult the requirements of the procedure: Identify the documents required by the relevant authority and whether they must be submitted as originals, authenticated copies or verifiable electronic documents.
-
Check whether an apostille or legalisation is necessary: Verify whether the issuing country is a party to the Hague Convention or whether an agreement provides an exemption.
-
Confirm the required type of translation: Check whether a sworn translation into Spanish is necessary or whether the authority accepts another form of official translation.
-
Review every element of the document: Ensure stamps, signatures, annotations, and additional pages are included, including the apostille where applicable.
-
Check the consistency of personal details: Compare names, surnames, dates of birth and identification numbers against the passport and other supporting documents.
-
Verify certificate validity: Make sure the documents are still within the acceptance period established for the procedure.
-
Keep the originals and copies: Retain copies of the submitted documents and their translations in case the authorities request additional information.
In Spain, the Ministry of Inclusion, Social Security and Migration outlines the general requirements for legalising and translating foreign public documents in its immigration guidance.
Consulting this information before preparing the paperwork helps applicants identify the formalities that apply to each document.
When an official translation is required, using an authorised professional can also help prevent formatting errors, omissions, and certification issues.
Conclusion
Immigration procedures do not depend solely on meeting the personal eligibility requirements for a residence permit. Applicants must also submit documentation that allows the authorities to verify their identity, criminal record and personal circumstances.
A missing apostille, a certificate outside its accepted validity period or a translation that omits relevant information can result in additional requests and unnecessary delays.
The best way to avoid these problems is to check the specific requirements for each procedure before requesting documents, complete the necessary authentication, and ensure translations meet the Spanish administration's requirements.
When it comes to immigration applications, getting the paperwork right from the beginning can make a significant difference to the process.
