For criminal cases, lawyers can only provide legal advice and defense opinions before the trial, but can't make the final judgment and handling of the case. Therefore, if the lawyer has defended the case and provided legal advice before the trial, there is not much to do before waiting for the trial.
A lawyer refers to a practitioner who has passed the national legal professional qualification examination, obtained a lawyer's practice certificate according to law, accepted the entrustment or designation, and provided legal services to the parties.
