Certified vs Notarised vs Sworn: What Differs

Four words get used almost interchangeably by people who need a document translated for use in Ireland: certified, notarised, sworn, apostilled. They are not the same thing, and using the wrong one costs time. A certified translation is what Irish authorities actually ask for. Notarisation is something a small number of private-sector recipients request on top of it. Sworn translation is a foreign system that has no Irish equivalent. Apostille legalises a document’s origin, not its translation. Here is what each one covers, and how to tell which your situation needs.

Certified: the Irish default

Ireland does not operate a state register of sworn translators the way France, Spain, Poland or Germany do. What Irish authorities accept instead is a certified translation: an accurate rendering of the full source document, accompanied by a signed Statement of Accuracy from the translator or translation provider. The Statement of Accuracy confirms four things: that the translation is complete and accurate, the translator’s or provider’s name, the provider’s contact details, and the date.

Immigration Service Delivery (ISD, formerly INIS), the Department of Justice, the Passport Office, the HSE, third-level admissions offices and Irish courts all accept this format without asking for anything further. Every certified translation we issue carries “Tatkowski Certified Translator” as the certifying name, our company registration and contact address, and the date, with a stamp on the physical copy where the receiving office wants one. No notary, no court officer and no government registry signs off on it. The translator’s professional signature is the whole mechanism, and it is enough.

Notarised: an add-on, not the default

Notarisation is a separate act performed by a notary public, who is usually a solicitor with additional notarial qualification. A notary does not check that the translation is linguistically accurate. What they certify is that the person who signed the Statement of Accuracy is who they claim to be, or that a copy of a document is a true copy of the original. It is a layer of identity or copy verification sitting on top of the translation, not a replacement for the Statement of Accuracy itself.

Irish public bodies rarely ask for it. ISD, the HSE and Irish courts work from the certified translation alone. Where notarisation shows up is in private-sector requests: some banks, some overseas property transactions, and some foreign courts or government departments that are used to a notarial system and ask for one out of habit, even where Irish law does not require it. If a specific letter or portal asks for a “notarised translation,” check whether they actually mean certified (most do) before booking notary time, because notary appointments add days and a separate fee that a certified translation alone does not need.

Sworn: not an Irish concept

“Sworn translator” describes a state-appointed status that exists in several continental European systems but has never existed in Ireland. Spain’s Traductor Jurado is appointed by the Ministerio de Asuntos Exteriores (MAEC) and signs with an official seal. France’s Traducteur Assermenté is registered with a Cour d’Appel. Poland’s Tłumacz Przysięgły is registered with the Ministerstwo Sprawiedliwości, the Ministry of Justice. Germany’s beeidigter or vereidigter Übersetzer is appointed by a regional court, the Oberlandesgericht. Italy takes a slightly different route: an ordinary translator’s work is formally sworn, asseverazione, before a judge or notary at the local tribunale.

All four systems hand the translator a state-conferred authority that carries its own registry number and seal. Ireland never adopted this model, so there is no Irish equivalent to point to and no Irish sworn-translator register to search. Two situations bring “sworn” into an Irish translation job anyway. First, a document produced abroad may already have been sworn and apostilled in its country of origin before it reaches Ireland, in which case the foreign sworn document is accepted alongside an Irish certified translation where one is still needed. Second, a document is going the other way, out of Ireland to a country whose authorities specifically require a sworn translator registered in their own system. In that case we produce the certified Irish-side translation and arrange sworn certification in the destination country through a partner network, rather than pretending an Irish certification can substitute for a foreign statutory requirement. The full comparison, with country-by-country detail, is on our sworn vs certified translation page.

Apostille: legalising the document, not the translation

The 1961 Hague Apostille Convention legalises the origin of a public document for use in another Convention country. An apostille confirms that a signature, seal or stamp on a document is genuine; it says nothing about who translated the document or how well. That distinction trips people up constantly, because apostille and translation often travel together in the same application without being the same step.

In Ireland, the Department of Foreign Affairs Consular Section issues apostilles, both on Irish public documents going abroad and, where a foreign authority specifically asks for it, on translations produced in Ireland. The current DFA fee is EUR 40, which we pass through at cost when a client needs it. The standard combination for most Irish use cases is: a certified translation of a foreign document, with an apostille applied only if the receiving authority names apostille as a requirement, not as a default extra. Skipping the certified translation and getting an apostille alone will not satisfy ISD, the HSE or an Irish court, because none of them are checking the apostille for language accuracy.

Which one does your document actually need

Work backwards from the receiving authority, not from the word a form uses. If the document is going to ISD, the HSE, an Irish university, the Passport Office or an Irish court, a certified translation with a signed Statement of Accuracy is the standard and usually the whole requirement. If a private recipient (a bank, an overseas conveyancer, a foreign employer) asks for “notarised,” confirm whether they mean certified before adding a notary appointment to the timeline. If the document originated abroad and already carries a sworn stamp from its country of origin, keep that stamp attached and add an Irish certified translation only if the receiving Irish authority still needs one in English. If the document is going abroad to a jurisdiction that names apostille specifically, get the apostille from the DFA and check whether the destination country wants a locally sworn translator on top of it, because an Irish certified translation will not automatically satisfy that requirement.

Most applications only need the first option. Certified translation is the floor every Irish authority accepts, notarisation and sworn translation are targeted add-ons for specific recipients, and apostille runs on a separate track that legalises the original document rather than the words on the page.

Three scenarios, worked through

Abstract rules are easier to apply with concrete examples attached. Three come up often enough to be worth walking through directly.

A Polish birth certificate needed for an ISD family reunification application. This is the simplest case. The document needs a certified translation with a signed Statement of Accuracy. No notary, no apostille, no sworn translator anywhere in the process, because the receiving authority is Irish and the Irish standard is certified translation alone. See our Polish translation page for how registry-office format affects the translation itself.

An Irish marriage certificate needed for a property purchase in Spain. This runs the other way, an Irish document going abroad to a jurisdiction that does operate a sworn-translator system. Spanish authorities and conveyancers frequently expect a Traductor Jurado’s seal on the Spanish-language version, not an Irish certified translation, even a correct one. The practical route is an Irish apostille on the original certificate from the DFA, followed by sworn translation into Spanish arranged through a partner in Spain, rather than assuming an Irish certification will be recognised by a system that has never accepted it.

A Ukrainian document already sworn and apostilled before it reached Ireland. Some Ukrainian civil documents pass through legalisation abroad before arriving in Ireland. Where that has already happened, the existing sworn stamp and apostille stay attached to the document, and what Ireland typically still needs on top is a certified English translation for ISD, the HSE or an employer to actually read it. Re-doing the foreign legalisation step is unnecessary and expensive; adding the missing certified translation is usually the only gap.

Each scenario turns on the same question: which authority is receiving the document, and does that authority sit inside the Irish certified-translation standard or a foreign jurisdiction with its own rules. Get that answer first and the rest of the paperwork follows from it.

Our certified translation pricing page covers per-page rates and turnaround if you already know a certified translation is what you need. If you are still unsure which category your document falls into, send us the receiving authority’s letter or portal instructions and we will tell you plainly which of the four you actually need before you pay for anything extra.
