How to Apostille US Documents in Barcelona for Use in Spain (2026 Guide)

If you are living in Barcelona and need to use a U.S. document in Spain, obtaining the correct apostille is often a key requirement. Whether you are submitting an FBI background check, birth certificate, marriage certificate, academic record, or power of attorney, the document must typically be authenticated before it can be presented to Spanish authorities.

One of the most common misconceptions is that U.S. documents can be apostilled in Spain. In reality, apostilles are issued by the competent authority in the country where the document was issued. This means U.S. documents must be apostilled by the appropriate U.S. authority, even if you are currently residing in Barcelona.

In this blog, we explain how to apostille U.S. documents while living in Barcelona, which authorities issue apostilles, and the steps required to prepare your documents for use in Spain.

The short answer is no. Spanish authorities, including those in Barcelona, cannot issue an apostille for a document that was issued in the United States.

Under the Hague Apostille Convention, an apostille must be issued by the competent authority in the country where the document originated. For U.S. documents, this means the apostille must be issued by either the relevant Secretary of State or the U.S. Department of State, depending on the type of document.

However, you do not need to be physically present in the United States to complete the process. Many individuals living in Barcelona arrange for their documents to be apostilled remotely through mail, authorized representatives, or professional document services.

Before starting the process, it is important to determine which U.S. authority is responsible for your document, as requirements differ for state-issued and federal documents.

The authority responsible for issuing an apostille depends on where the document was issued. One of the most common reasons apostille requests are delayed or rejected is that documents are sent to the wrong authority.

In the United States, apostilles are generally issued by either a state authority or a federal authority.

State-Issued Documents

Documents issued by a U.S. state are typically apostilled by the Secretary of State in the state where the document originated. Common examples include:

• Birth certificates
• Marriage certificates
• Death certificates
• State court documents
• Notarized powers of attorney
• Notarized affidavits
• Business documents filed at the state level

For example, a California birth certificate must be submitted to the California Secretary of State, while a New York marriage certificate must be apostilled by the New York Department of State.

Federal Documents

Documents issued by a U.S. federal agency require an apostille from the U.S. Department of State. Common examples include:

• FBI Identity History Summary Checks
• Federal court documents
• Certificates issued by federal agencies
• Certain immigration and naturalization records

Because federal and state documents follow different procedures, identifying the document type before submitting an application is an important first step.

If you are unsure whether your document is state-issued or federal, checking the issuing authority can help determine the correct apostille route and avoid unnecessary delays.

Although U.S. documents cannot be apostilled in Spain, the process can still be completed while you are living in Barcelona. The key is identifying the correct issuing authority and ensuring the document meets all apostille requirements before submission.

Step 1: Identify Whether Your Document Is State-Issued or Federal

The first step is determining which authority issued your document. State-issued documents, such as birth certificates, marriage certificates, and many notarized documents, are generally apostilled by the Secretary of State in the issuing state. Federal documents, such as FBI background checks, require an apostille from the U.S. Department of State.

Submitting a document to the wrong authority is one of the most common causes of delays.

Step 2: Obtain the Correct Original or Certified Copy

Most authorities require either the original document or a certified copy issued by the appropriate office. Photocopies are generally not accepted unless they have been properly notarized and meet the requirements of the issuing authority.

Step 3: Complete Any Required Notarization

Certain private documents, including powers of attorney, affidavits, declarations, and certified copies, may need to be notarized before they can be apostilled.

Requirements vary depending on the document type and the state responsible for issuing the apostille.

Step 4: Submit the Document to the Appropriate Apostille Authority

Once the document is ready, it must be submitted to the correct U.S. authority:

• State-issued documents → Secretary of State in the issuing state
• Federal documents → U.S. Department of State

Processing methods may include mail submissions, courier services, authorized representatives, or apostille service providers.

Step 5: Receive the Apostilled Document in Barcelona

After the apostille has been issued, the document can be returned to Spain for use with the relevant authority, employer, university, court, or government office.

Depending on the purpose of the document, an official Spanish translation may also be required before submission.

In many cases, an apostille alone is not enough for a U.S. document to be accepted by a Spanish authority. If the document is written in English, a Spanish translation may also be required before it can be submitted as part of an official application.

Translation requirements can vary depending on the authority receiving the document. Immigration offices, civil registries, universities, courts, and other public bodies may have their own document requirements, so it is important to confirm what is needed before submitting your paperwork.

What Is a Sworn Translation?

For many official procedures in Spain, foreign-language documents must be translated by a sworn translator (traductor jurado). A sworn translation is an official translation that carries the translator's certification and is legally recognized by Spanish authorities.

When Might a Sworn Translation Be Required?

A sworn translation is commonly requested when submitting documents such as:

• Birth certificates
• Marriage certificates
• FBI background checks
• Academic records
• Court documents
• Powers of attorney

The exact requirement will depend on the authority handling your application.

Should the Apostille Be Obtained Before Translation?

As a general rule, the document should be apostilled before arranging the final sworn translation. This ensures that both the original document and the apostille can be reflected in the translated version when required.

If you are unsure whether your document needs a sworn translation, it is best to verify the requirements with the Spanish authority requesting the document before proceeding.

In most cases, no. If a U.S. document has been properly apostilled by the competent U.S. authority, additional consular legalization is generally not required for use in Spain.

This is because both the United States and Spain are parties to the Hague Apostille Convention. The Convention simplifies the recognition of public documents between member countries by replacing the traditional legalization process with a single apostille certificate.

For applicants in Barcelona, this means that once the document has received the correct apostille, it can generally be presented directly to the relevant Spanish authority, subject to any translation or application-specific requirements.

However, an apostille only confirms the authenticity of the signature, seal, or stamp on the document. It does not guarantee that the receiving authority will accept the document for a particular purpose. Authorities may still have their own requirements regarding document validity, translations, or supporting paperwork.

If you are submitting documents for immigration, employment, education, or civil registration purposes, it is always advisable to confirm the exact requirements with the organization requesting the document.

Many Americans living in Barcelona discover that obtaining an apostille is only one part of the process. Depending on the requirements of the Spanish authority, you may first need to obtain a new FBI background check or other supporting document before the apostille can be issued.

Apostille and Translation Coordination

Once the required document has been obtained, Globeia can coordinate the apostille process through the appropriate U.S. authority- the US Department of State for federal documents such as FBI Identity History Summaries, or the relevant Secretary of State for state-issued documents on your behalf.  If a sworn Spanish translation is required, translation support can also be arranged to help prepare the document for submission in Spain.

Applying for an apostille may seem straightforward, but small mistakes can lead to delays, rejected applications, or the need to restart the process. If you are arranging an apostille from Barcelona, avoiding the following issues can help ensure your documents are accepted without unnecessary complications.

Sending the Document to the Wrong Authority

One of the most common mistakes is submitting a document to the wrong apostille authority. State-issued documents and federal documents follow different procedures, and sending them to the incorrect office can result in rejection or significant delays.

Using an Uncertified Copy

Many apostille authorities require an original document or an officially certified copy. Submitting a standard photocopy when a certified document is required will typically result in the application being returned.

Overlooking Notarization Requirements

Certain private documents, such as powers of attorney, affidavits, and declarations, may need to be notarized before they are eligible for an apostille. Requirements can vary depending on the document type and issuing jurisdiction.

Forgetting Translation Requirements

Even after a document has been apostilled, the receiving authority in Spain may require a sworn Spanish translation before accepting it. Failing to verify translation requirements can delay immigration, employment, academic, or civil registration applications.

Assuming an Apostille Confirms the Content of a Document

An apostille verifies the authenticity of the signature, seal, or stamp on a document. It does not validate the accuracy of the information contained within the document itself.

Waiting Until the Last Minute

Apostille processing times can vary depending on the issuing authority, document type, and delivery method. Leaving the process until shortly before a visa appointment, university deadline, or legal filing date can create unnecessary pressure and increase the risk of delays.

Assuming Spain Can Apostille a US Document

Many applicants believe they can obtain a U.S. document apostille directly in Barcelona. However, apostilles must be issued by the competent authority in the country where the document originated. U.S. documents must therefore be apostilled through the appropriate U.S. authority before they can be used in Spain.

Whether you're applying for residency, employment, studies, or another official process in Spain, ensuring your U.S. documents are properly prepared can help prevent unnecessary delays and complications. By understanding the apostille requirements in advance and following the correct process, you can submit your documents with greater confidence.
