Irish Citizenship Translation: What to Translate for Naturalisation

Here's a scene we see a lot. Someone has lived in Ireland for six years. They've used the residency calculator twice, counted their days abroad to the hour, and built a folder of payslips thick enough to stop a door. Then, the night before they submit, they spot the birth certificate in Portuguese, Polish or Arabic and wonder whether the whole folder now needs translating.

It doesn't. The heavy part of an Irish citizenship application, proving where you've lived and for how long, is made of Irish documents. The translation part is usually small, but it has to be done properly, by a professional, and in full. Let's work out exactly what yours is.

What Are the Translation Rules for Irish Citizenship?

Applications for naturalisation are decided by Immigration Service Delivery (ISD) on behalf of the Minister for Justice. According to Citizens Information, if your supporting documents are in a language other than English, you must get them translated by a professional translating service.

Two words in there do a lot of work. Professional means a DIY translation, or one by your bilingual cousin, won't do, however fluent they are. And a translation means the whole document: every stamp, margin note and registrar's scribble, not a summary of the parts that seem important.

There's one useful exception. Certain official documents from an EU country, Iceland, Liechtenstein, Norway or Switzerland don't need translating if they come with a Multilingual Standard Form (MSF) from the issuing authority. If your birth certificate comes from, say, Poland or Spain, it's worth asking the registry whether they can attach one before you pay anyone to translate it.

Who Can Apply for Irish Citizenship by Naturalisation?

Your route decides your paperwork, so it's worth a quick recap. These are the conditions as Citizens Information sets them out (page updated 22 September 2026):

• The standard route: one year of continuous reckonable residence immediately before you apply, plus four years in total during the eight years before that. That's five years out of the last nine. You can spend 70 days outside Ireland in that final year, with up to 30 more in exceptional circumstances.
• Spouse or civil partner of an Irish citizen: married for three years or more, three years of reckonable residence on the island of Ireland out of the last five (Northern Ireland counts on this route), 12 months continuous before you apply, and living with your spouse.
• Refugees: five years of reckonable residence for applications received from 8 December 2025. Earlier applications stay under the previous three-year rule.
• Children: a parent or guardian applies on their behalf, with different residence rules.

Not every stamp counts. Time on a student permission (Stamp 2 or 2A) generally isn't reckonable unless you apply as a young adult, so check your dates with the ISD residency calculator before you order anything. A translation you don't need yet is money spent on an application you can't make.

Which Irish Citizenship Documents Need Translating?

Anything you send that isn't in English. In practice, these are the documents that turn up in other languages:

We have document guides for the most common ones: birth certificate translation, marriage certificate translation and divorce certificate translation. If you can't get a document at all, ISD expects an explanation and, for a missing birth certificate, an affidavit form, which you download from the ISD website.

What Can You Leave in English? The Scorecard Pile

ISD uses a scorecard for identity and residence: you need 150 points in each, and residence is scored for every year you claim. The Citizenship Guidance Document sets out how many points each type of document is worth. For identity, a certified colour copy of the biometric page of your current passport is the document most people rely on.

Here's the good news. The residence half, which is by far the biggest pile, is made of documents from your life in Ireland. Those were never in another language to begin with:

So if anyone offers to translate your five years of Irish bank statements into English, politely decline. They're already there.

Certified Copies vs Certified Translations: Not the Same Stamp

This is where applications get muddled, because two different things are both called "certified".

• A certified true copy confirms a photocopy matches the original. For naturalisation, your birth certificate, passport and, on the spouse route, your marriage certificate and your spouse's birth certificate must be certified by a solicitor, notary, commissioner for oaths or peace commissioner. Documents issued in an EU country, Iceland, Liechtenstein, Norway or Switzerland don't need certifying in Ireland.
• A professional translation confirms the English text accurately reflects the original. Ours comes with a dated certification page carrying our company details, the copy of your original it was made from, and the full translation.

A solicitor certifying your copy doesn't translate it, and our certification doesn't replace the solicitor. You typically need both. Many people get their copies certified when they make their statutory declaration, so book the translation first and bring everything to that one appointment.

How Much Does Irish Citizenship Translation Cost?

We price per page: €20.99 per page for standard delivery within 24 working hours, or €35.99 per page for rush delivery within 8 hours. Prices include VAT, and there's no minimum. Here's what four typical applications look like:

The wildcard is the divorce file. A short divorce certificate is one page. A full court judgment with the reasoning, the financial settlement and the custody arrangements can be eight or more, and it all gets translated. If you have a choice between a short official certificate of divorce and the full judgment, check which one ISD's list asks for before you send us the longer one.

Upload your documents and you'll see the exact page count, price and guaranteed delivery date before you pay. With the application fee at €175 and a certification fee of up to €950 for most adults if you're approved, the translation is the smallest line in the budget. It's also the line most likely to cause a delay if it's missing.

Applying on the Spouse Route? Your Pile Is Bigger

Applications based on marriage or civil partnership to an Irish citizen need documents that show your spouse's nationality and evidence that you've been married for three years. Your spouse's Irish documents are in English. Your marriage certificate may not be, especially if you married in your home country.

If either of you was married before, add the papers that ended the earlier marriage. A marriage certificate tells ISD you're married. The divorce decree tells them you were allowed to be. Both need translating if they aren't in English. Our guide to divorce certificate translation was written for UK visas, but what it says about long court judgments applies here too.

How to Get Your Citizenship Documents Translated

Living in Northern Ireland or Applying for the UK Instead?

Spouses of Irish citizens can count legal residence in Northern Ireland, so plenty of applicants live north of the border. The Irish rules above still apply to the Irish application. If you're weighing up British citizenship as well, the paperwork is different: our guide to documents to translate for UK naturalisation covers that side, and certified translation in Northern Ireland covers UK visas for people living there. We translate from over 200 languages into English for both.
