Article 35 of The Basic Law of the Hong Kong Special Administrative Region of the People's Republic of China ("Basic Law") guarantees right to confidential "legal advice". The law enables the Client to repose full trust in his Attorney and disclose all information that he think will assist his Attorney in the trial while making representaion on his behalf. Public policy mandates that the Attorney so trusted with confidential information cannot break the privilege on his own accord and always use the information in the best interest of the Client. The said law shall apply to all cases where (a) legal advice is sought or given and (b) actual or contemplated representaion in a litigation is made. The documents covered could be anything under the sun. Even oral information is confidential and cannot be disclosed. This applies to lawyers and his staffs and Clients and his representatives. Parties can waive the right to privileged information. Having said that, this privilege cannot be exercised in cases of fraud or conspiracy to commit a crime in the future.
