Can amateur lawyers go to court?

First of all, if you go to court as an agent or defender, in criminal cases, employees need to have a lawyer's business license, so as long as there is a lawyer, you can participate. However, if you participate as a witness, there are certain conditions, such as the on-the-job police and the staff of the local law enforcement agency. Even if you have a lawyer's license, your attendance status is restricted in some cases, so it depends on your amateur nature. If you don't involve these, it is ok.
