Division 4 of Part 16 of the Companies Ordinance contains regulation of names used by registered non-Hong Kong companies to carry on business in Hong Kong. If the Registrar of Companies ("the Registrar") is satisfied that a corporate name is "the same as" or is "too like" a name that appears, or should have appeared, in the Registrar's index of company names, or gives so misleading an indication of the nature of its activities in Hong Kong as to be likely to cause harm to the public, the Registrar may, within 6 months of the date on which the corporate name is registered, serve a notice to that effect on the company.
If a registered non-Hong Kong company is served with such a notice, it must not, after the end of 2 months after the date of service, carry on business in Hong Kong under that corporate name. The company may either cause the name for which the notice is served to be changed in the place of its incorporation or apply, in writing, to the Registrar for approval of another name in substitution of that name under which it is to carry on business in Hong Kong.
For details, please refer to the Guideline on Registration of Corporate Names for Registered Non-Hong Kong Companies.
