- For names containing the words government, bank, assurance or insurance, or derivatives of these, you must provide additional supporting documents.
Additional details for registration
- You indicate whether the registrant is an organisation or an individual. All of the domain's contacts must fall into the same category.

Transfer
Transferring a .com.hk

Owner
Change of registrant
Change of registrant
- The new registrant must also be based in Hong Kong. The registrant's name or organisation can only be changed through an official change of registrant.
- For a change of registrant, you fill in a special form. This form and all supporting documents are combined into a single PDF and submitted. WebOké will help you with this.
- If the current registrant is a Hong Kong company, it must include an extract from the companies register dated no more than 30 working days before the date of the request letter.
- If the current registrant is a company outside Hong Kong, the signed declaration form DCTNR1 is required. This must be accompanied by a recent document, no more than 30 working days old, showing that the signatory is authorised.
