Commercial and Company Document Translation for Switzerland

The first question to answer when preparing commercial paperwork for Switzerland is not “which document” but “which canton” and “which language”. This page deals with the documents a company established in Türkiye will put before a register, a bank or a business partner in Switzerland; a Swiss company opening a liaison office in Türkiye is a separate process running the other way.

Cantonal, not federal: two variables at once

The commercial register in Switzerland is kept at cantonal level. This means the same document can be asked for in a different language, and at times in a different form of approval, in Zurich and in Geneva. German, French and Italian are official languages; whichever the target canton uses is the language the translation is made into. Confirming in writing, before the file is prepared, which canton your counterpart is in and which language it corresponds in removes the risk of having a second translation made later. Because of the weight of international banking and trade, some institutions accept an English translation as well; that, however, is not a rule but an institutional preference.

The documents that establish a Turkish company’s identity

The core set a Swiss counterpart expects runs to four items: a currently dated certificate of activity showing that the company is still trading, the trade registry gazette notices showing its incorporation and the changes since, the articles of association carrying the shareholding and objects clauses, and the signature circular showing authority to represent. For account openings and financing files, declarations as to the shareholding structure and the beneficial owner are added to these. Because the translation of those declarations has legal effect it is subject to the full chain, whereas promotional material in the nature of internal correspondence is not. Submitting the certificate of activity together with the trade registry gazette notice matters particularly: the notice shows how the company was formed and what changes it has been through, while the certificate of activity confirms that it is trading as at today. Sending only one of the two is the shortest route to a “missing document” reply from your counterpart.

Approval: the notarised translation tradition

There is no central sworn translator regime in Switzerland; the established practice is for the translation to be notarised. The translator’s signature is verified before a notary and, where needed, an apostille is added to that notarisation. For a translation produced in Türkiye the chain is symmetrical: the sworn translator’s signature, notarisation, then an apostille from the governor’s office or the district governor’s office. Switzerland is a party to the Hague Apostille Convention; even so, since practice can differ from one canton to another, it is advisable to verify the current list of parties through the HCCH and to obtain written confirmation from your counterpart.

Decision point	What to ask	The cost of a wrong answer
Canton	In which canton will the transaction be dealt with?	The document goes to the wrong authority
Language	German, French or Italian?	The translation is done over from scratch
Level of approval	Is notarisation required?	The papers are sent back on receipt
Date of the document	How recent a copy is accepted?	It is treated as out of date

Export paperwork runs on a separate line

Because Switzerland is not a member of the European Union, customs paperwork works differently from the Union countries; proof of origin and preferential tariff documents follow the route of chamber of commerce approval and the customs administration. Those documents, along with the commercial invoice and the packing list, fall outside the sworn translation process. The sworn translation and apostille chain is for documents with legal effect: contracts, powers of attorney, register records, court papers. Adding transport and customs paperwork to the translation file enlarges both the time and the cost for nothing.

The separate burden of bank and financing files

Opening an account or making a financing application in Switzerland is heavier going than a conventional commercial file. The institution asks you to evidence not merely that the company exists, but who controls it and where the funds come from. Alongside the register record and the signature circular, therefore, come a declaration of the shareholding structure, a statement of beneficial ownership and, more often than not, recent financial statements. Consistency of terminology is decisive in translating financial statements: the same item appearing under a different equivalent in two places in the file leads the institution to ask for further explanation. Running the translation of files of this kind through one pair of hands and one term list cuts the number of follow-up questions directly.

Powers of attorney, tender files and the commonest ground of refusal

If a transaction in Switzerland is to be carried out by your local representative, have the power of attorney drawn up before a notary, obtain its apostille before having it translated, and support the grantor’s authority with a current register record. In tender and supplier registrations the commonest ground of refusal is a mismatch of language: the right document, the right approval, the wrong language. Second comes the date of the document, and third the translation having been detached from the copy of the original. Read the manner of delivery from the specification; institutions that want a stamped, wet-signed set are still in the majority.
