Sworn translation and apostille: the order almost everyone gets wrong

The mistake that costs people money and time

If you've been told a foreign document (a diploma, a marriage or birth certificate, a bank statement, a company document) needs to be "apostilled and translated" for use with a Polish office, the order matters — and a lot of people get it backwards, paying for a sworn translation first and then discovering they needed to apostille the original document before translating it, not after.

The correct order

1. Apostille the original document first, in the country that issued it. An apostille is a certification (under the Hague Apostille Convention) that verifies the document's authenticity for use abroad — it needs to be attached to the original before translation, not to a translated copy.
2. Then get a sworn translation (tłumaczenie przysięgłe) of the document together with its apostille — a Polish sworn translator (tłumacz przysięgły) translates both the original content and the apostille certification itself, so the Polish office receives a complete, translated package that shows the full chain of authentication.

Doing it the other way around — translating first, then trying to apostille — generally doesn't achieve what the receiving office needs, because the apostille is meant to authenticate the original document, not a translation of it.

When you might not need an apostille at all

Not every country requires an apostille for its documents to be recognised abroad — this depends on international agreements between Poland and the issuing country. Some countries' documents are recognised without an apostille under bilateral agreements, while others require it. Check with the Polish office requesting the document, or the relevant consulate, before assuming an apostille is (or isn't) required — this varies enough by country that a general rule isn't reliable here.

Who needs a sworn translator specifically

For most official Polish procedures (residence applications, marriage registration, university admissions, business registration), a translation from any translator generally isn't accepted — it needs to come from a tłumacz przysięgły, a translator sworn in and certified specifically for legal/official translations in Poland. A quality general translation from someone else, however accurate, typically won't be accepted for these purposes.

Practical summary

1. Confirm whether your document's country of origin requires an apostille for Poland (check with the receiving office).
2. If yes: apostille the original first.
3. Then: get a sworn translation of the whole package (document + apostille) from a tłumacz przysięgły.
4. Submit the complete translated package to the relevant Polish office.

This is general information, not legal advice

Requirements vary by document type, issuing country, and the specific office requesting it. Confirm the exact requirement with the office or institution asking for the document before starting the process, since redoing it after a mistake costs both time and translation fees twice.
