在香港，如果要認證正式文件和重要文件，有三種方法，稱為公證、認證和合法化（Notarisation, Apostille and Legalisation）。您將需要為公司把重要文件進行“身份驗證”，包括必須為合約或公司文件進行認證，然後才能在公司的所在國家/地區以外的地方使用它們。在某些情況下，您可能需要在香港進行文件公證、認證或合法化，例如在海外開設銀行戶口、在中國開設外商獨資企業（WOFE），或您與一家在海外註冊運營的公司達成協議時。

In Hong Kong, if you want to authenticate official documents and important documents, there are three methods called Notarization, Apostille and Legalization. You will need to "authenticate" important documents for your company, including having to authenticate contract or company documents before they can be used outside of the company's home country. In some cases, you may need to notarize, authenticate or legalize documents in Hong Kong, such as when opening a bank account overseas, opening a wholly foreign-owned enterprise (WOFE) in China, or when you enter into an agreement with a company registered and operating overseas .
