1: If both parties have gone through marriage registration procedures, and one party does not agree to divorce, the other party needs to go to the original registration authority to issue a marriage status certificate, and then go to the court to sue for divorce.
2: Both parties have already gone through marriage registration, and if both parties agree to divorce, they can go through divorce procedures at the marriage registration office.
3: If the two parties have not gone through the marriage registration procedures, the "husband and wife relationship" of both parties is not protected by law and can be separated by agreement. However, if there is a dispute over property and child custody, it can be handled in court.
