A Sworn Translation of a Power of Attorney into Spanish: What Spain Will Actually Accept

Only the client’s first name is used here. The family, the property, the dates and the contents of the deed have been changed or omitted entirely.

Paula found the right page on our site before she wrote to us, which tells you something. Her message was nine words — she needed a sworn translation of a power of attorney — and the form recorded the direction as English into Spanish, fifteen pages, no notarisation requested, purpose family and personal. Under certification she had put “Unsure”, which was the only honest answer available to her.

Almost everything about that enquiry was unusually well judged. She had used the word sworn rather than certified, which is the distinction most people get wrong, and she had got the direction right: this was a British document going out to Spain, not a Spanish one coming in. A sworn translation of a power of attorney into Spanish is a specific product with specific gatekeepers, and the first thing we owed her was a straight answer about who those gatekeepers are — including the possibility that the answer cost us the job.

The request was precise, and that is rarer than it sounds

Most enquiries about documents bound for Spain arrive asking for a certified translation, because that is the phrase British people know. Certified is the UK product. It means a complete translation accompanied by a signed statement from the translator confirming accuracy and identifying them, and it is what UK authorities ask for.

Spain does not work that way, and asking for a sworn translation signalled that Paula either knew that or had been told it by somebody on the Spanish side. We asked which, because it changes the brief. In this case a Spanish professional had used the phrase traducción jurada to her. That is the magic word, and it means the requirement came from the reader rather than from a guess.

A UK certified translation and a Spanish traducción jurada are not the same instrument

This is the heart of it, and we say it plainly on our sworn translation services page too, because it is the single most expensive misunderstanding in outbound work.

Spain maintains an official register of sworn translators and interpreters — traductores-intérpretes jurados — appointed through the Spanish foreign ministry. A translation produced by one of those appointees carries their seal, their signature and a prescribed certification wording, and in Spain that package is what gives a translated foreign document official standing. Several countries run comparable systems; France, Italy and others keep their own registers.

The United Kingdom keeps no such register. There is no British equivalent of a sworn translator, and no amount of care, qualification or professional membership creates one. So a UK certified translation, however well executed, is not a traducción jurada. Handed to a Spanish notary, a Spanish land registry or a Spanish bank that has asked for a jurada, it can simply be declined — not because it is wrong, but because it is the wrong instrument.

We told Paula that in the first reply. We also told her the practical consequence: where a Spanish reader has specified a jurada, the translation needs to come from an appointee on the Spanish register, and if that is what her situation requires then that is where the work belongs, with us or without us. Saying so loses us occasional orders. It loses clients far more than an order when nobody says it.

Where a Spanish reader has not specified a jurada — and plenty have not, particularly private companies, insurers and some administrative uses — a complete certified translation may be perfectly acceptable, and we provide that. The test is never what sounds safest. It is what the reader asked for, in writing.

Fifteen pages usually means a registered LPA, and the registered version is the one to translate

The page count was informative. A short general power of attorney runs to two or three sheets. Fifteen pages, for a private family matter, almost always means a statutory lasting power of attorney on the English form, with its prescribed sections, its certificate provider’s part, its attorney declarations and its continuation sheets.

That changes the sequence, and getting the sequence wrong is how people pay twice.

An English lasting power of attorney is not operative on signature. It has to be registered with the Office of the Public Guardian, and the registered instrument carries the office’s own markings. The version worth translating is the registered one. Translate an unregistered copy and you have a faithful English-to-Spanish rendering of a document that has no effect yet — and when the registered version arrives, with its additional markings, you are buying the translation again.

So the first question we asked Paula was not about Spanish at all. It was whether the deed had been registered, and whether what she held was the registered instrument with the office’s markings on its face or an earlier copy. The second question was how many of the fifteen pages were continuation or guidance sheets, because the statutory form is issued with explanatory material that is not part of the instrument. There is no point paying to translate a page of English government guidance on how to fill in a form.

The apostille is a page of the document, not a cover sheet

A UK deed going to Spain usually needs authenticating as well as translating. Both countries are party to the Hague apostille arrangements, and in the United Kingdom the apostille is issued by the Legalisation Office of the Foreign, Commonwealth and Development Office. The apostille attaches to the UK document and certifies the signature and seal on it; it says nothing whatsoever about the translation.

Three things follow, and they are the three things clients are not told often enough.

The order matters. Authenticate first, translate afterwards. An apostille obtained after the translation is finished is an extra page that the finished translation does not account for — so you are back for a top-up.

The apostille itself must be translated. It is a numbered certificate with its own fields: the country, the signatory, the capacity in which they acted, the place and date, the issuing authority, the certificate number and the seal. A Spanish reader checking the chain expects to be able to read all of it. Leaving it untranslated because it looks like administrative furniture is a common and entirely avoidable mistake.

And the set must not be taken apart. Original deed, apostille and translation travel as one bundle, in that relationship, with the translation stating what it is attached to.

Our power of attorney translation service sets out the add-ons, including notarisation and legalisation, and the published guidance there is explicit that a foreign authority may ask for notarisation or an apostille. Paula had ticked no for notarisation, and for a UK instrument heading to Spain with an apostille that was the right call — the apostille route and a notarial certificate answer different questions, and buying both without being asked for both is simply an extra invoice.

Words that look as though they translate, and do not

Then there is the language, which on a deed is the part where confidence is dangerous.

An English power of attorney and a Spanish poder notarial are not the same legal animal, and the vocabulary does not line up neatly. Spanish practice distinguishes a poder general from a poder especial, and has its own instrument — the poder preventivo — for the situation an English lasting power of attorney addresses. A Spanish reader coming to a translated English deed brings those categories with them.

The translator’s rule on a document like this is to render, never to convert. The donor of an English LPA becomes the otorgante, and the attorney the apoderado — and that second one has to be right, because abogado means lawyer and an attorney under an LPA is very often not one. Call the attorney an abogado and you have told the notary something untrue about who is standing in front of them.

Institutions keep their English names, with a short explanatory gloss in Spanish. The Office of the Public Guardian is the Office of the Public Guardian; the Court of Protection is the Court of Protection. Neither has a Spanish counterpart, and inventing one — substituting some nearby Spanish body — would tell the reader that an institution exists which does not. The same goes for the statutory wording of the form and for the prescribed declarations: they are reproduced as what they are, with the structure of the English instrument visible through the Spanish, so that a notary can see which part of the deed they are looking at.

Dates, reference numbers and the registration markings are transcribed exactly. Nothing is reformatted into a Spanish house style, because an identifier is data.

The question we asked that could have cancelled the order

Last, and most important, we asked Paula what the document was for — who in Spain was going to be handed it, and what they intended to do with it.

We ask because there is an honest answer that loses us the job. If a Spanish notary is going to act on a power of attorney in a transaction in Spain, it is very often cleaner, faster and cheaper to execute a poder notarial drawn in Spanish in the first place — before a notary in Spain, or at a Spanish consulate in the UK — than to translate and authenticate a long English instrument and hope the notary is content with it. Notaries vary in what they will accept, and some are markedly reluctant to act on a translated foreign deed when a native Spanish instrument is available.

That advice does not always apply. Where the donor cannot travel, where capacity is already in question, where the English deed is already registered and operative, or where the Spanish side has specifically asked for the English instrument to be translated, the translation route is the right one and sometimes the only one. The point is that it is a question with consequences, and it should be asked before money changes hands rather than afterwards.

What we delivered

What Paula took away was, in order: a note of which version of the deed to send us and why the registered one matters; a recommendation to get the apostille before the translation rather than after; the names of the two Spanish categories a notary is likely to be thinking in; and a plain statement that if her Spanish contact had asked for a traducción jurada, the certification has to come from Spain’s own register and we would say so rather than sell her the UK product under a Spanish name.

On the pages she did commission, the work was a complete Spanish rendering of the instrument as issued — every prescribed section, every declaration, the registration markings and the apostille fields described in place, nothing summarised and nothing left out, with the English institutional names kept and glossed. Attached to it was our certification: a signed, dated statement that it is a complete and accurate translation of the documents supplied, with the translator identified and contactable. Guidance sheets that form no part of the instrument were identified and excluded from the quote, and that exclusion was stated on the certification so that nobody could mistake it for an omission.

Our published pricing for sworn work starts from around £45, and for a certified document translation from £25 per page, with standard delivery in two to three working days, express at 24 hours, and same-day for orders placed before midday. Quoting a fifteen-page bundle properly means knowing how many of those pages are the deed, which is why the page question came before the price.

Where it landed

The work went out inside the agreed deadline, complete, certified, and matched to the authentication chain rather than cutting across it. Nothing came back queried with us, and Paula told us the advice about registering first and apostilling before translating had saved her from doing the whole thing in the wrong order.

What a Spanish notary ultimately accepts is a matter for that notary, and we would not claim otherwise about any outbound document. Our part is that the bundle went out the door in the shape the Spanish side described, with the limits of a British certification stated rather than glossed over.

If you are sending a UK power of attorney to Spain

The sequence, in the order it actually has to happen.

Ask the Spanish reader, in writing, whether they require a traducción jurada. Keep the reply. It decides everything else.

Register the deed first if it is a lasting power of attorney, and work from the registered instrument.

Obtain the apostille before commissioning the translation, and remember the apostille has to be translated too.

Separate the instrument from the guidance sheets before you ask for a price.

And ask whether a Spanish poder executed in Spanish would serve you better. If the answer is yes, that is a cheaper afternoon than this one.

For documents coming the other way — a Spanish deed or power of attorney that a UK conveyancer, lender or court needs in English — our certified legal translation service is the right starting point, and the overview of which documents require legal translation in the UK covers the usual list.

Questions we are asked about Spanish sworn translations

Can a UK translator produce a sworn translation for use in Spain?

Not in the Spanish sense. Spain recognises translations certified by sworn translators appointed through its own foreign ministry and listed on its register. The UK has no equivalent register, so a UK certified translation is a different instrument. If your Spanish reader has asked for a traducción jurada, that is what you need, and anyone telling you otherwise is selling you a risk.

Will a Spanish notary accept a translated English lasting power of attorney?

Some will, some will want more, and some would rather you executed a Spanish poder instead. It depends on the notary and on the transaction. Ask before you commission the translation — it is a short email and it can change your whole approach.

Does the apostille need translating as well?

Yes. An apostille is a certificate with its own numbered fields, not a cover sheet, and a reader checking the chain of authentication expects to be able to read it. Get the apostille first, then translate the document and the apostille together.

Should I notarise the power of attorney as well as apostilling it?

Only if you have been asked to. Notarisation and apostille answer different questions, and for a registered UK instrument going to Spain the apostille route is commonly what is wanted. Our notarisation step is available as an add-on when a reader genuinely requires it.

My LPA has not been registered yet. Can you translate it now?

We can, but we would advise against it. An English lasting power of attorney takes effect on registration and the registered instrument carries markings the unregistered copy does not. Translating the earlier version usually means paying for the translation twice.

Do you charge for the guidance pages that come with the form?

No. The statutory form arrives with explanatory material that is not part of the deed. We identify it, exclude it from the quote, and state the exclusion on the certification so that it reads as a deliberate scope decision rather than a gap.

How are the English legal terms handled in Spanish?

Rendered, not converted. Spanish equivalents are used where they genuinely correspond — otorgante for donor, apoderado for attorney — and English institutional names such as the Office of the Public Guardian are kept with a Spanish gloss, because substituting a Spanish body would describe an institution that does not exist in your document.

If you are sending a British deed abroad and are not certain whether you need a UK certified translation or a sworn translation from the destination country’s own register, tell us which country and which reader and we will tell you straight — including when the answer is that the work is not ours to do. You can start an order here, read what is included in a notarised translation if that turns out to be the requirement, or send us the question with the page count and the destination.
