Regarding .hk registration, the registrant is required to submit to a mandatory arbitration proceeding in the event that a third party (a "Complainant") asserts to the applicable Provider that:-
(i) the domain name is identical or confusingly similar to a trademark or service mark in Hong Kong in which the Complainant has rights; and
(ii) the registrant has no rights or legitimate interests in respect of the domain name; and
(iii) the registrant's domain name has been registered and is being used in bad faith.
To succeed in the arbitration proceeding, the Complainant must prove that all of these three elements are present.
