How to translate your website's terms and conditions

A website whose terms and conditions exist only in one language creates a practical problem the moment users from other markets start accepting them. It is not just a question of accessibility — in several European jurisdictions, consumer-facing contracts must be presented in the local language to be enforceable.

What makes terms and conditions different from other web content

Terms and conditions are a contract. They define user obligations, liability limitations, refund policies, applicable jurisdiction, and dispute resolution mechanisms. A mistranslation in marketing copy is an embarrassment. A mistranslation in a contractual clause can create an obligation the original text never intended, or invalidate a limitation of liability altogether.

The same applies to related documents — privacy policy, cookie policy, legal notice. These form part of the same regulatory and contractual package and should be translated with equal care.

Which languages to prioritise

The decision should follow commercial reality, not guesswork. Three signals are worth examining:

• Website traffic by country — Google Search Console shows where users are coming from before they even convert.
• Existing customer base — if the company already processes orders from German or Dutch customers, those language versions are overdue.
• Local regulatory requirements — Germany, France, and several other EU member states have specific rules on the language of consumer contracts.

Vertio's engine supports over 70 languages, with verified quality across 9 active languages: Portuguese, English, Spanish, French, German, Italian, Dutch, Polish, and Romanian.

Choosing the right level of translation for legal documents

Terms and conditions use technical-legal vocabulary where precision is not optional. Free tools such as Google Translate or DeepL translate loose text — not documents — and apply no quality verification. The output may be fluent and still be legally inaccurate.

For most commercial websites and SaaS platforms, the right choice is a translation with human review. This means a qualified professional confirms that the legal meaning has been preserved in the target language — not just the words. For documents with direct legal consequences in a specific jurisdiction, such as binding contracts or regulatory submissions, a certified translation under ISO 17100 is the appropriate standard.

The Verificada tier covers most e-commerce and SaaS use cases. The ISO 17100 tier is for situations where the translation itself may be scrutinised in a legal or regulatory context.

How to prepare the source document

The quality of a translation depends partly on the quality of the source. Before uploading, it is worth checking:

• Terminological consistency — if the document alternates between "user" and "customer" without distinction, that ambiguity will carry through to the translation.
• Clean formatting — well-structured headings, numbered clauses, and clearly delimited sections make it easier to preserve the document's layout in the translated version.
• Current version — translating an outdated draft means doing the work twice. Confirm the source document reflects the version currently live on the site.

Supported formats include .docx, .pdf, .txt, and .pptx, up to 10 MB and 20,000 words per file.

Translating terms and conditions with Vertio

Vertio accepts the document file directly, runs it through the proprietary translation engine with automatic quality verification, and returns the translated document with formatting intact — ready to publish. For terms and conditions on a commercially active website, the Verificada tier (€49/1,000 words) includes human reviewer oversight alongside automatic verification. Where the translated document will carry direct legal weight — binding agreements, regulatory filings, court-admissible contracts — the ISO 17100 tier (€89/1,000 words) provides translation by M21Global's certified translators, backed by over 20 years of experience and 300 million words translated.

Frequently Asked Questions

Are website terms and conditions legally required to be translated?

In several EU member states, including Germany and France, consumer contracts must be presented in the local language to be enforceable. Even where there is no explicit legal obligation, providing translated T&Cs reduces the risk of disputes and improves user trust.

Can I use a free tool like Google Translate to translate my terms and conditions?

Free tools translate loose text without quality verification and do not preserve document formatting. For a contractual document like T&Cs, a translation error can alter the meaning of a clause, so a solution with quality verification and, ideally, human review is recommended.

What is the difference between the Verificada and ISO 17100 tiers for legal documents?

The Verificada tier combines the proprietary translation engine with automatic quality verification and a human reviewer — suitable for most commercial websites. The ISO 17100 tier uses M21Global's certified translators and is appropriate for documents with direct legal consequences, such as binding contracts or regulatory submissions.

Should I also translate my privacy policy and cookie policy?

Yes, if the website serves users in other languages. These documents form part of the same contractual and regulatory package as the T&Cs and should be translated with the same level of care to ensure compliance and user clarity.

What file formats does Vertio accept for document translation?

Vertio accepts .docx, .pdf, .pptx, .txt, .json, and .md files, up to 10 MB and 20,000 words per file.
