The lawyer's duty of confidentiality includes the lawyer's duty of confidentiality, that is, a lawyer comes into contact with the client's personal privacy, business secrets or other personal data and information in his practice, and may not disclose it to a third party, including the media or even state organs, without the client's consent. In practice, in order to understand the case, lawyers inevitably need to know a lot of materials, information and evidence of their clients. Some of these contents are customer privacy, some are trade secrets, and some are not privacy and trade secrets, which will adversely affect their customers. Lawyers have the responsibility to keep secrets for their clients. The confidentiality obligation of lawyers is determined by their professional nature, legal obligations of lawyers and contractual obligations of entrustment. Even if there is no confidentiality obligation in the contract, the lawyer's confidentiality obligation cannot be exempted. Of course, if the client authorizes the lawyer to disclose relevant information, the lawyer is allowed to disclose any privacy or business secrets without exceeding his authority. Lawyers who violate confidentiality obligations and cause reputational losses or economic losses to their clients shall be liable for compensation. Bian Xiao's summary ends here.
