Look at the contract you signed with the law firm, how much you represented in the first instance and the second instance, or agree to represent the first instance and the second instance for free. Most of them do. The lawyer receives the money first. In the first case, it is only the first trial, depending on the content of your agency contract.
In the second case, after receiving the materials, the court should consider them as criminal categories and transfer them to the case-handling organ. Lawyers shouldn't have done much work, so they can return it. If he doesn't return it, he can report it to the Legal Affairs Office of the Judicial Bureau.
