Legal analysis: You can entrust a lawyer to help you with relevant legal matters, but you also need to appear in court in person. If a husband and wife divorce voluntarily, they must register for divorce at the marriage registration office where one of them has a permanent residence. Therefore, if both parties agree to divorce, they need to bring the household registration book, ID card, marriage certificate and divorce agreement signed by both parties and go to the Civil Affairs Bureau to handle the divorce formalities in person. They can't entrust a lawyer to handle the divorce formalities and get a divorce certificate.
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.
