Do close relatives need to issue a certificate of relationship when entrusting a lawyer?

Legal analysis: If it is a civil case, close relatives are not needed. If it is a criminal case, lawyers usually invite close relatives. Lawyers will look at household registration information. If it is not used in the same household registration book, a certificate must be issued, otherwise it is unknown whether the entrustment is legal.

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

Article 919 An entrustment contract is a contract in which the principal and the agent agree that the agent shall handle the principal's affairs.

Article 922 The agent shall handle the entrusted affairs in accordance with the instructions of the principal. If it is necessary to change the client's instructions, it shall be approved by the client; If it is difficult to get in touch with the client due to an emergency, the agent shall properly handle the entrusted affairs, but shall report the situation to the client in time afterwards.
