Checklist: choosing the language of a document or of proceedings

Identify the native or working language of the client and of the client’s advisers, as well as the languages of the countries in which the document will take effect.
Draft in the language that ensures the best understanding by the parties and the greatest legal certainty in the countries of enforcement.
Where the drafting is multilingual, designate the authoritative version by means of a prevailing-language clause and verify that the versions correspond.
For arbitration, choose the language of the proceedings according to the parties, the arbitrators available and the documents.
Provide for the certified translations needed for enforcement in non-French-speaking countries.
Make sure that the practitioners responsible for the drafting command the chosen language at the required level, including its national legal particularities.

Dr Alexander Ressos, TEP

Rechtsanwalt/Attorney-at-Law

I am a Swiss attorney-at-law and also admitted as a solicitor in Hong Kong and in England & Wales, with almost 25 years of experience.

Together with my multilingual team, including Chinese, Japanese, Korean, Russian, Ukrainian and French native speakers, I advise companies and their owners from around the world on the full range of banking, corporate, commercial and tax law matters in Switzerland, including international tax planning, fiduciary services, and legal family office services including immigration & relocation or real estate investments. My practice has a particular focus on clients from growth and frontier markets in Greater China, Central Asia and the Caucasus, the rest of Asia, the Middle East, Africa and Latin America, and I equally advise clients from Europe and North America. Through an affiliated Swiss trust company, we also take care of the incorporation and ongoing administration of their companies and other structures, including accounting, tax returns and corporate secretarial services, and I serve as a professional director where required. With the support of a network of first-class cooperation partners, I also implement solutions worldwide.

My approach is to act as a trusted advisor who works directly with decision-makers, on an equal footing: I start from what you want to achieve and shape every structure, contract and tax decision around your commercial goals and how it improves your after-tax return. As “lawyers who make it happen”, my team and I stay involved until your company is set up, your structure is in place and your transaction has closed, and we remain available for any follow-on work that may be required. You benefit from bespoke solutions and personal attention, and sound, friendly and practical advice. We are not the lowest-cost provider in the market, nor do we intend to be; our aim is to deliver well-founded, proper solutions and excellent value for money.
