Lawyers have the obligation to keep secrets from their clients, which is the obligation of lawyers to practice. However, according to the provisions of Article 46 of the Criminal Procedure Law of People's Republic of China (PRC), defense lawyers have the right to keep confidential the relevant information and information of their clients they know in their practice activities. However, if the defense lawyer knows that the client or others are preparing or committing criminal acts that endanger national security, public security and seriously endanger the personal safety of others, he shall promptly inform the judicial organs.
If it is not "preparing or committing crimes that endanger national security, public safety and seriously endanger the personal safety of others", the defender has no obligation to inform.
