Do I need to inform the court in advance to bring a lawyer to court?

Subjectivity of law: no need.

Before the trial, the lawyer's preparation work includes collecting some evidence related to the litigation claim, because these evidence need to be submitted to the court for trial. Of course, if some evidence cannot be collected by yourself, you can apply to the court for investigation when necessary and entrust a lawyer to handle related matters. If it is the plaintiff's family, you can make the following preparations:

1. Collect evidence related to the litigation request and apply to the court for investigation if necessary.

2. If you are not familiar with laws and regulations, you can entrust a lawyer as an agent to represent the case.

If it is the defendant's family, you can make the following preparations:

1. After receiving the copy of the indictment, collect evidence around the litigation request to prove that the plaintiff's request has no legal basis.

2. Submit a defense to refute the plaintiff's claim.

3. If necessary, you can entrust a lawyer as an agent to represent the case.
