The entrustment procedure includes the following contents: (1) The law firm and the client sign an entrustment agreement in duplicate. One is sent to the client and the other is filed by the law firm. (2) The power of attorney signed by the client is in duplicate. One is submitted to the case-handling organ, and the other is filed by the undertaker; (3) The letter of introduction issued by the law firm shall be submitted by the lawyer to the case-handling organ.
