Legal analysis: Whether the summoned person can entrust a lawyer to appear in court depends on the nature of the case. According to the relevant laws and regulations, if it is a divorce case, the summoned person must appear in court unless there are special circumstances; However, in other cases, the summoned person may entrust an agent to appear in court instead of appearing in court himself. However, if another person is entrusted to represent the lawsuit, a power of attorney signed or sealed by the client must be submitted to the people's court, and the power of attorney must be clearly stated.

Legal basis: People's Republic of China (PRC) Civil Procedure Law.

Article 62 If there is an agent ad litem in a divorce case, I shall appear in court unless I can't express my feelings. If it is really impossible to appear in court due to special circumstances, a written opinion must be submitted to the people's court.
