"Article 59 When a person appoints another to act on his behalf in litigation, he must submit to the people's court a power of attorney bearing his signature or seal."
The power of attorney must specify the matters entrusted and the powers conferred.
"An agent ad litem must obtain special powers from his principal to admit, waive or modify claims, or to compromise or to file a counterclaim or an appeal."
A power of attorney mailed or delivered through others by a citizen of the People's Republic of China residing abroad must be certified by the Chinese embassy or consulate accredited to that country.
"If there is no Chinese embassy or consulate in that country, the power of attorney must be certified by an embassy or a consulate of a third country accredited to that country that has diplomatic relations with the People's Republic of China, and then transmitted for authentication to the embassy or consulate of the People's Republic of China accredited to that third country, or it must be certified by a local patriotic overseas Chinese organization."
