Legal analysis: the law does not expressly prohibit it. In judicial practice, if the lawyer of first instance and his relatives appeal on his behalf, the court will seek the opinions of the defendant. According to the relevant laws and regulations of our country, whether the first-instance lawyer is only responsible for submitting the appeal materials depends on the power of attorney signed by both parties. If there is no agreement, he is generally only responsible for the end of the first instance.

Legal basis: Article 59 of People's Republic of China (PRC) Civil Procedure Law entrusts others to represent the lawsuit, and a power of attorney signed or sealed by the client must be submitted to the people's court. The power of attorney must specify the entrusted matters and authority. An agent ad litem must have the special authorization of the client, and can admit, waive or change the claim, make a settlement, file a counterclaim or appeal on his behalf. The power of attorney sent or entrusted by China * * and China citizens living abroad must be authenticated by China * * and China's embassy or consulate in that country; If there is no embassy or consulate, it shall be certified by the embassy or consulate of a third country that has diplomatic relations with the people of China, and then by the people of China and the embassy or consulate of China in a third country, or by the local patriotic overseas Chinese delegation.
