There are two options for divorce. The first is divorce by agreement, and the second is divorce by litigation. If the two parties agree to divorce by agreement, they can take their marriage certificates, household registers, ID cards, divorce agreements, photos and other materials to the Civil Affairs Bureau where either party's household register is located for divorce registration. If you just want to divorce, and the other party does not agree to divorce, you can only sue for divorce. But litigation for divorce takes a long time, and the procedure is complex. If there is no legal divorce, the court is unlikely to decide for divorce, A second lawsuit is required to divorce (legal divorce situations: domestic violence, abandonment, abuse, drug abuse, gambling, bigamy, imprisonment, emotional discord and separation for more than two years, physical defects or diseases that are difficult to cure, etc.).
