Bid documents are among the most important materials determining a business’s success in participating in international or domestic tenders. To ensure that the documents are accepted and legally valid, notarized translation of bid documents is an essential step. At No.1 Translation, we provide fast, accurate translation solutions that comply with legal standards, helping clients confidently submit their documents on time and increase their chances of winning the bid.
Why Is Notarized/Certified Translation of Bid Documents Necessary?
Notarized or certified translation of bid documents is a mandatory requirement in many tenders, especially for projects involving foreign elements or led by international or joint venture organizations. A notarized translation not only verifies the authenticity of the content but also ensures legal validity, helps prevent disputes, and allows the bidder to demonstrate professionalism and transparency to the tendering party. It is also a prerequisite for the documents to be considered valid and not disqualified during the prequalification stage.
Some cases where notarized translation of bidding documents is required include:
- Participating in tenders invited by foreign enterprises or organizations.
- Bidding for ODA, FDI, EPC, or BOT projects involving international investors.
- Original documents are prepared in Vietnamese but must be submitted in English, Chinese, Japanese, etc.
- The procuring entity requires clearly notarized or certified translations.
- Documents must be submitted to authorities for licensing, evaluation, or contractor qualification verification.
- The contractor is part of an international consortium and needs a unified working language.
