What do I need to submit to change my lawyer before the trial?

About the application for changing the litigation agent, the agency procedures of the new lawyer, and the lawyer's appearance in court issued by the law firm. If the agency procedures of the lawyer you originally hired are not submitted to the people's court, it is not necessary to submit an application for changing the agent ad litem to the court when changing the lawyer. Just ask the lawyer you hired now to submit the agency procedures and the letter of appearance to the court.
