Let’s start with the definition of a certified true copy.

What is a Certified True Copy?

A certified true copy is an official version of the original document, certified by a qualified professional as being true and accurate to the former. The qualified professional stamps the copies to prove they can be used to substitute the original documents.

However, a certified true copy isn’t proof that the original documents are authentic. For example, a certified true copy of a document that had been stolen or forged isn’t evidence of the original documents’ authenticity. 

Purpose of a Certified True Copy

Certified true copies are required where the individual or company needs to apply for important personal or company documents. Since third parties are not allowed to retain the original documents, certified true copies are used as a substitute instead.

In Hong Kong, a certified true copy is required in the following instances:

  • When opening a corporate bank account in a Hong Kong bank
  • When applying for a business license
  • When engaging in international transactions
  • Legal purposes
  • Government proceedings

For example, when opening your company’s bank account you’ll be asked to present the following certified copies:

  • Certified copies to prove identity of shareholders and directors where a national ID, passport or driver’s license can be used
  • A certified true copy to prove residential address which can be done using a recent utility bill 
  • True copies of company incorporation documents including articles of association, registration certificate, and registers of shareholders and directors

These requirements may vary from bank to bank, so you should enquire first with your bank which documents are needed to avoid certifying the wrong documents.

Format of a Certified True Copy

The format of a certified true copy is determined by the certifier. Still, in most cases, the following information should be included:

  • Name and signature of certifier
  • Certification date
  • A statement with wordings such as:  “I confirm that this is a true copy of the original” or “Certified to be a true copy of the original seen by me”
  • Professional stamp of certifier
  • Position of certifier
  • Number of pages

In Hong Kong, the certified true copies must be in Chinese or English. If the documents are in another language, they must be translated.
