But it's best to entrust your lawyer with full authority. You don't have to appear in court. If you are here, if the judge asks some sensitive questions, your answer is abrupt, even if it is true, it is likely to be bad for you. When you are not in court, when the judge asks your lawyer, he can bring back the question and answer it appropriately after consulting with you, which may be much better.
Except for divorce cases, you must appear in court in such cases.
