Sworn Translation in Poland: What Foreign Families Need

Every foreign document you present to a Polish court, bank, tax office, or registry must be translated into Polish by an authorized sworn translator. Not a regular translator — a specifically licensed professional. Getting this wrong means your documents are rejected and your deadlines keep ticking.

Who Can Provide a Valid Sworn Translation

Polish institutions accept translations only from three categories of authorized professionals:

1. A sworn translator (tłumacz przysięgły) registered with the Polish Ministry of Justice. These translators hold a state license and appear on an official public list maintained by the Ministry. This is the most common route.

2. A sworn translator licensed in an EU or EEA member state. Their qualifications are recognized across the EU under mutual recognition agreements.

3. A Polish consular officer holding jurisdiction over the country where the document was issued. Polish consulates can translate and certify foreign documents directly.

Regular commercial translation services — no matter how qualified — are not accepted. The translator must stamp the document with their official seal and register number.

What Documents Need Sworn Translation

For estate settlement in Poland, these typically need sworn translation:

• Foreign birth certificates — to prove family relationships for inheritance claims
• Foreign marriage certificates — to establish spousal rights
• Foreign death certificates — when the death occurred outside Poland but assets are in Poland
• Foreign wills — to establish testamentary succession in Polish proceedings
• Powers of attorney — to authorize someone in Poland to act on your behalf
• Court documents — foreign probate decrees, guardianship orders
• Autopsy reports — if obtained from the prosecutor's office (these aren't automatically provided to families in Poland; an attorney must petition for a copy)

Documents issued within the EU often don't need sworn translation if you use the multilingual standard forms available under EU regulations. Poland's multilingual death certificate (odpis skrócony wielojęzyczny) is accepted across EU member states without additional translation.

The Apostille Requirement

Documents issued outside the EU must be authenticated before they can be used in Poland:

• Hague Convention countries (US, UK, Canada, Australia, and 100+ others): Get an apostille from the designated authority in the issuing country. In the US, this is usually the Secretary of State's office in the state where the document was issued.

• Non-Hague countries: Documents must be legalized by a Polish consular post in the issuing country — a more complex and time-consuming process.

The apostille certifies that the document is genuine. It doesn't translate it — you still need the sworn translation on top of the apostille.

Costs and Timelines

Simple documents (birth certificates, death certificates) take 1-3 business days to translate. Complex documents (wills, court orders, powers of attorney) can take a week or more.

Cost-saving tip: The multilingual abridged death certificate from Poland's Civil Registry (22 PLN) is accepted across EU countries without any translation. If you need the death certificate for use in Germany, France, or another EU state, this version saves you the entire translation cost.

The NIP-7 Form

Foreign heirs who need to interact with Polish tax authorities (filing SD-Z2 for inheritance tax exemption, handling capital gains on property sales) may need to obtain a Polish tax identification number (NIP). The application is filed on Form NIP-7 with the local Tax Office. The form itself is in Polish — a sworn translator can help complete it, or your Polish attorney can file it on your behalf.

Forensic Autopsy Document Access

If the death was sudden or suspicious, Polish authorities may have ordered a forensic autopsy. The autopsy report is part of the prosecutor's investigation file and is not automatically shared with the family. To obtain a certified copy, the family must hire a licensed Polish attorney (adwokat) to petition the prosecutor's office. The report will be in Polish and may need sworn translation for use abroad.
