Translating Documents for International Inheritance Cases

May 11, 20267 min read

When an estate spans more than one country, whether through property held abroad, heirs living overseas, or a will drafted under a foreign jurisdiction, correctly translated and certified documents are a legal requirement, not a procedural nicety. A mistranslation in a death certificate, a will, or a power of attorney can suspend probate proceedings or invalidate actions already taken.

Which documents require translation in a cross-border estate

The list of documents that typically need translation in an international inheritance case is extensive. The most common include:

  • Wills and codicils, including foreign wills to be recognised domestically or domestic wills to be executed abroad
  • Death certificates, issued by the country where the death occurred
  • Birth and marriage certificates of heirs and the deceased
  • Identity documents (passports, national identity cards, residency permits)
  • Property deeds and land registry documents for assets held in foreign jurisdictions
  • Bank statements and proof of asset ownership
  • Powers of attorney granted abroad for representation in probate proceedings
  • Court decisions from foreign tribunals, where judicial partition is involved

Each of these documents requires translation accompanied by the correct form of certification for the receiving country. There is no universal standard: requirements vary by jurisdiction.

Certified, sworn, or apostilled: understanding what is required

This distinction is where most cross-border estate cases run into difficulty. These three concepts are not interchangeable.

Simple translation carries no legal weight before public authorities. It is suitable for internal reference or preliminary review only.

Certified translation is signed by a qualified professional translator who attests to the accuracy and completeness of the translation. In many European countries, certified translations are accepted in notarial and registry contexts when accompanied by a signed declaration from the translator.

Sworn translation is produced by a translator who holds official recognition from a competent authority and whose work carries the legal weight of a sworn statement. It is mandatory in certain countries and for certain document types. For more on when sworn translation is required, see the article on sworn translation for court documents.

The Hague Apostille legalises the original document, not its translation. For documents originating in countries party to the Hague Convention, an apostille removes the need for consular legalisation. The apostille and the certified translation of that document are two separate requirements, both of which are typically mandatory.

For estates involving two or more EU member states, EU Succession Regulation No. 650/2012 provides a common framework for the recognition of succession decisions. Even so, each national authority still requires documents to be accompanied by a translation in the local language, certified to the appropriate standard.

What determines the level of certification required

The answer lies with the receiving country, not the country that issued the document. The key factors are:

  • The destination country: each state defines what forms of certified translation it accepts for foreign documents in succession proceedings
  • The receiving authority: a court imposes different requirements from a land registry, a bank, or a notary
  • The nature of the document: wills and court decisions typically require more rigorous certification than bank statements
  • The language pair: in some jurisdictions, only translators holding specific national accreditation are recognised for legal documents

Verifying requirements with the notary, solicitor, or court managing the case before commissioning translations avoids the risk of submitting a correctly translated document at the wrong certification level, which will be refused.

Common mistakes that delay international probate

Most delays in cross-border estate proceedings that stem from translation errors are preventable.

Incomplete translation: many official documents include marginal notes, endorsements, or apostille text that form part of the document. If the translation omits these elements, the receiving authority is entitled to reject it.

Certification mismatched to the destination: a certified translation prepared to Portuguese standards may not be accepted in France, Germany, or Brazil without adaptation to local requirements.

Translating before apostilling: if the original document will be apostilled after translation, any visible changes to the document (such as an apostille stamp or certificate attached) may require the translation to be redone.

Imprecise legal terminology: terms such as "forced heirship", "collation", "intestate succession", or "grant of probate" have specific equivalents in each legal system. A translation that substitutes approximate equivalents for precise technical terms can be challenged in proceedings.

This is why certified legal translation services for estate documents must involve translators with grounding in comparative succession law, not only general linguistic competence.

Frequently Asked Questions

What type of translation is required for a foreign will to be valid in the UK?

In England and Wales, a foreign will must typically be accompanied by a certified translation when submitted to the Probate Registry. The translator should sign a statement of accuracy. Requirements may vary depending on the language pair and the nature of the estate, so confirming with the relevant solicitor or probate authority is advisable.

Does an apostille replace the need for a certified translation?

No. An apostille authenticates the original document; translating the content of that document is a separate and equally obligatory step. The two are complementary requirements, not alternatives.

Does the EU Succession Regulation remove the need for translation within the EU?

No. EU Regulation No. 650/2012 facilitates cross-border recognition of succession decisions but does not remove the obligation to present foreign documents with a certified translation in the local language of the receiving authority.

How long does translation of inheritance documents take?

Timelines depend on the volume of documents, the language pair, and the certification level required. Urgent processing can often be arranged, but documents with direct legal effect in succession proceedings require specialist review, which sets a minimum turnaround time. Contact M21Global with the specifics of the case for a realistic estimate.

Can inheritance documents be translated between English and less common languages such as Arabic, Mandarin, or Russian?

Yes. M21Global works with over 40 languages, including non-European ones. For less common language pairs, confirming translator availability with legal specialisation in the specific combination in advance is recommended.
