A power of attorney issued in Portugal is not automatically valid abroad. To be accepted in Spain, France, or the United Kingdom, it requires a certified translation and, in most cases, an apostille under the Hague Convention. Exactly what is required depends on the destination country and the purpose of the document.
Why a domestic power of attorney is not enough abroad
A power of attorney used exclusively in Portugal is a straightforward notarial document, recognised by Portuguese notaries and registries. Once it needs to operate in a foreign jurisdiction, a different set of requirements applies.
The receiving authority in the destination country needs two things: confidence in the authenticity of the document issued in Portugal, and a clear understanding of its content. These two elements involve separate processes. Authentication of origin is handled through the apostille mechanism. Accuracy of content is handled through certified legal translation.
Confusing the two, or attempting to handle them in the wrong order, is the most common cause of rejected documents.
Country-specific requirements: Spain, France and the UK
Spain and Portugal are both signatories to the 1961 Hague Convention. A Portuguese power of attorney intended for use in Spain must first be apostilled by the Portuguese Ministry of Justice, then translated into Spanish by a *traductor jurado* — a sworn translator recognised by the Spanish Ministry of Foreign Affairs. The sequence matters. The apostille goes on the original document. The translation is then made from the apostilled version.
France applies the same Hague Convention framework. The document must be apostilled in Portugal, then translated by a *traducteur assermenté*, a translator accredited by a French court of appeal. French authorities apply strict standards to legal terminology. A translation that uses literal equivalents without accounting for functional differences between the Portuguese and French legal systems is likely to be challenged or rejected.
The United Kingdom presents a specific situation following Brexit. The UK remains a signatory to the Hague Convention, so the apostille continues to serve as the mechanism for authenticating the original document. There is no official register of sworn translators in the UK. British authorities and solicitors generally accept translations accompanied by a signed statement from the translator or translation company, confirming the accuracy and completeness of the translation. The credibility of that statement depends on the credentials of the company or translator providing it.
Apostille, certified translation and sworn translation: how they differ
These three terms are frequently used interchangeably, but they refer to distinct things with distinct functions.
- Apostille: A certificate issued by a competent authority in the country of origin — in Portugal, the Ministry of Justice or notarial registries, depending on the document type. It authenticates the signature and capacity of the notary or official who signed the document. It says nothing about the content.
- Certified translation: A translation accompanied by a signed statement of accuracy from the translator or translation company, typically including a stamp and reference to the language pair. This is the minimum required in many international contexts.
- Sworn translation: In Portugal and most civil law countries, this refers to a translation produced by a translator formally recognised by the relevant authorities, carrying official status. The equivalent in Spain is the *traductor jurado*; in France, the *traducteur assermenté*.
For powers of attorney, the standard rule is: apostille first, certified translation second. Reversing the order means the translation no longer corresponds to the apostilled document and the process must restart.
For documents intended for court proceedings, the requirements follow a related but distinct set of rules, covered in more detail in the article on sworn translation for court documents.
Practical mistakes that delay or invalidate the process
Most delays and rejections come down to a small number of recurring errors.
Commissioning the translation before obtaining the apostille is the most frequent. The apostille physically alters the document by adding stamps and references. Any translation produced before that stage no longer matches the final apostilled version.
Using a translator not recognised by the destination country's authorities is a close second. A linguistically accurate translation can be rejected on purely formal grounds if the translator lacks the required credentials for that jurisdiction. This is particularly relevant for Spain and France, where the requirements are clearly codified.
Finally, powers of attorney often contain clauses granting specific legal powers — representation before registries, signing authority for property transactions, banking mandates. These concepts do not map neatly across legal systems. A translator who only knows the language pair, without knowledge of the destination legal system, can produce a translation that creates ambiguity where the original was precise.

Frequently Asked Questions
Does a Portuguese power of attorney need an apostille to be used in Spain?
Yes. Both Portugal and Spain are party to the Hague Convention, so an apostille issued by the Portuguese Ministry of Justice is the standard mechanism for authenticating the document. The Spanish sworn translator (*traductor jurado*) then translates the apostilled version.
What is the difference between a certified translation and a sworn translation for a power of attorney?
A certified translation is accompanied by a signed statement of accuracy from the translator or translation company. A sworn translation is produced by a translator formally recognised by the authorities of the destination country, such as a *traductor jurado* in Spain or a *traducteur assermenté* in France, and carries official legal status in that jurisdiction.
Does the UK still accept apostilled documents after Brexit?
Yes. The UK remains a signatory to the Hague Convention, so apostilles issued by Portuguese authorities continue to be recognised. The translation into English must be accompanied by a signed statement of accuracy from a credible translator or translation company.
What happens if the translation is done before the apostille is obtained?
The apostille physically alters the original document by adding stamps and reference details. A translation produced before that stage will no longer correspond to the apostilled version, and the translation will need to be redone.
How long does a certified translation of a power of attorney typically take?
A straightforward power of attorney can generally be translated and certified within 24 to 48 working hours. Turnaround depends on document length, the language pair, and the level of legal complexity. It is worth confirming deadlines directly with the translation provider.
