“Certified” or “sworn”? The distinction that decides your application

Most people arrive looking for a “certified translation,” because that is the term used in the UK and the US. It is worth understanding exactly what it means for a Polish matter, because the wrong kind of translation — a certified one where a sworn translation was needed — is one of the most common reasons a Polish citizenship by descent file is returned.

A sworn translation (tłumaczenie przysięgłe) is produced by a tłumacz przysięgły — a translator sworn in and entered on the official register held by the Polish Ministry of Justice. Every page of a sworn translation carries the translator’s official round seal and repertory number, and a record of it is entered in the translator’s repertorium, which is open to government inspection. This is the standard that Polish consulates, voivodeship offices, civil-registry offices and courts require, and every translation is duly stamped and signed under Ministry of Justice registration TP/122/24, exactly as Polish law requires.

A “certified translation” of the kind common in the United States and the United Kingdom — a translation accompanied by a signed statement of accuracy, the format accepted by USCIS and US courts — is a different thing, and so is a “notarised” translation. Polish authorities will typically not accept either for a citizenship confirmation, civil-registry or court matter. It is not a question of quality: an excellent, word-perfect certified translation can still be refused, because what the Polish office checks is the legal form.

Confirming citizenship you may already hold

Polish citizenship may be held by descent from a Polish parent, grandparent or great-grandparent, regardless of where you were born and whether or not you have ever used it. For most descent applicants the process is therefore not a grant of new citizenship but a confirmation of Polish citizenship you already hold — potwierdzenie posiadania obywatelstwa polskiego — passed down an unbroken line. A Polish passport is an EU passport, carrying the right to live, work, study and retire anywhere in the European Union.

Magdalena Fowler is a sworn translator, not a lawyer, and does not advise on eligibility for Polish citizenship by descent. Whether your particular ancestor, dates or documents establish the claim is a legal question for you, your own research or a qualified adviser, and for the Polish authority that decides. What she provides is sworn translation, without which your foreign documents cannot be used.

For many families the application is about far more than a passport. It is a way of reconnecting with a grandparent’s or great-grandparent’s story: the parish in Galicia or Masuria where a birth was first recorded, the ship that carried a young man to Liverpool or New York, the soldier who settled in Britain after the war rather than return to a Poland under Soviet control. Gathering the documents often brings that family history together for the first time, and the sworn translation is the means by which those records are made decipherable to the Polish authorities responsible for citizenship claims.

The practical reasons are just as varied. Some applicants want the freedom to live, work or study anywhere in the European Union, some plan to retire in Europe, some have children whose options they want to widen, and many British applicants simply want back the European rights they lost with Brexit. Whatever the reason, many applicants are surprised how manageable the paperwork turns out to be once the right documents are gathered and in order.

Keep your British or US passport

The first worry of many descent applicants is whether confirming Polish citizenship means giving up the citizenship they were born with. It does not. Polish citizenship by descent sits alongside an existing nationality, and the result for most applicants is two passports: the British or US one they already hold and a Polish passport, which is also an EU passport.

The United Kingdom permits dual nationality, so a British citizen who confirms Polish citizenship remains fully British, with nothing to renounce. The United States does not require a citizen to renounce US citizenship on acquiring another, and US citizens commonly hold a second passport; US law does expect a US citizen to enter and leave the United States on the US passport. Individual circumstances vary, particularly for anyone holding a third citizenship or working in a sensitive government post, so applicants should take their own advice on their own position.

Poland accepts that its citizens may hold another nationality, but under the Act on Polish Citizenship of 2 April 2009 it treats a Polish citizen solely as Polish while dealing with them. In practice that means a dual national travels into and out of Poland as a Polish citizen, on a Polish passport or Polish identity card, and uses the British or US passport at home. Within the European Union, the Polish passport gives the right to live, work, study and retire anywhere in the EU without a visa or work permit.

Holding both passports also helps the next generation. Once a parent’s Polish citizenship has been confirmed, their children can in turn have their Polish citizenship confirmed and their births registered in Poland. The Polish passport itself is applied for after the confirmation decision, and the process usually also involves entering the applicant’s foreign birth certificate, and often a marriage certificate, into the Polish civil register, a step called transcription (transkrypcja). Every foreign certificate used for transcription needs a sworn translation into Polish too, so it pays to have the whole set sworn-translated once, consistently, at the start.

Which documents need sworn translation

Once you, or your adviser, have confirmed which documents your application requires, every non-Polish one needs a sworn translation into Polish, and they are best translated together as a set. Most often that begins with birth certificates — your own, and those of the Polish parent, grandparent or great-grandparent through whom the claim runs. Marriage certificates usually follow, because they establish the chain of descent and record the name changes that happen between generations, and death certificates of the ancestor or ancestors may be needed where the authority requires them to complete the chain. Where they are relevant to the line or to someone’s marital status, divorce decrees and annulments need a sworn translation too.

Naturalisation and citizenship records are often pivotal, because they show when — and whether — an ancestor acquired another citizenship abroad. In some application contexts, extracts or certified copies of passports and identity documents are also needed. Wherever any of these documents carries an apostille, the apostille is translated with it as part of the same sworn translation.

Note the direction: for Polish citizenship by descent, the sworn translation runs into Polish, by a Poland-registered sworn translator, and not into English as a US agency would do for USCIS. Documents already in Polish need no translation at all.

The apostille, and getting the order right

Foreign civil documents usually need an apostille in the country that issued them before they are translated, because the apostille becomes part of the document and must be translated with it. The ordinary order is to obtain the document, apostille it where required, and then have the whole thing sworn-translated into Polish. If the order is reversed, the apostille added afterwards is untranslated and the document usually has to be translated a second time. Confirm with the receiving authority exactly what is needed and in what form; getting the sequence right once avoids paying for the same sworn translation twice.

Old handwritten and archival records

Descent cases often turn on nineteenth- and early twentieth-century parish and civil records, handwritten and sometimes in Russian- or German-partition script, because before 1918 the registers in much of Poland were kept in the language of the occupying administration. The sworn translation of these records is routine work here, and reading them accurately is exactly where care matters: a sworn translator may only render what can be seen and understood, and may never guess, so where something is genuinely illegible the translation says so plainly. A clear, well-lit scan lets the record be read — and priced — accurately. Where a record is in Russian or German rather than English, it needs a translator sworn for that language; Magdalena Fowler does not translate these herself, but she can recommend trusted sworn colleagues for them from her many professional contacts.

How it works, and how it’s delivered

The whole process is simple and fully remote, in four steps:

A sworn translation of a standard document of one to three pages is typically ready in one to two working days, and a longer document in three to five; very long documents can take longer, and the exact timescale, which depends on current workload, is confirmed with the quote. Delivery is by eIDAS-qualified electronic PDF, valid across the EU, or on paper by courier or post, where the delivery time depends on the courier or postal service used (for the US, a courier or USPS) and is confirmed with the quote. Citizenship applications generally require the paper original by courier, so check what your receiving office accepts before choosing. A sworn translation can be made from a copy, which is fastest and needs no handover, or from the original, which gives the widest acceptance; where an in-person visit isn’t practical, the original can be verified remotely by other means.

Nothing has to be sent abroad before work begins. The translation is started from a scan or a clear photograph sent by email or WhatsApp, so no time is lost waiting for the post. A translation sworn from a copy means the original certificates never leave the applicant’s home, and where a paper translation sworn from the original is the better choice, the documents travel by tracked post and are returned with the finished translation. Family records carry personal details going back generations, so every document is handled confidentially, in line with the European Union’s General Data Protection Regulation (GDPR), and is used only to produce the translation. Anyone who would rather talk a document through before sending it can find every way to get in touch on the contact page.

The same certification, at a keener price

Every sworn translation in Poland is priced by the standard page — 1,125 characters of the finished translation — and that basis is the same for every sworn translator in the country. Overheads are not. Working from the Masurian countryside rather than central Warsaw means lower costs, and that saving is passed on to you: the same Ministry-registered certification and the same legal validity, at a price set by village overheads rather than city-centre rent. The village has high-speed fibre-optic broadband, a connection not yet available in every part of Warsaw, and the local town is served by all the major couriers, with a next-day collection account with InPost, so documents travel as quickly as they would from the capital. Sworn translation starts from £8 / €10 per page, and every price is quoted on the actual document and confirmed before any work begins. Upload a document for an instant quote →
