Can a lawyer terminate the entrustment relationship without authorization?

Legal analysis: after accepting the entrustment, a lawyer may not refuse to defend or represent without justifiable reasons. However, if the entrusted matter is illegal, the client uses the services provided by the lawyer to engage in illegal activities, or the client deliberately conceals important facts related to the case, the lawyer has the right to refuse to defend or represent him.

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

An entrustment contract is a contract in which the principal and the trustee agree that the trustee will handle the principal's affairs.

Article 922 The trustor shall handle the entrusted affairs according to the instructions of the trustor. 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.
