According to the provisions of China's laws, the first thing to see is whether the time when both parties meet the substantive requirements of marriage is before or after February 1, 1994. If the two parties met the substantive requirements of marriage before February 1, 1994, they have formed a de facto marriage relationship even though they have not gone through marriage registration. At the time of divorce, they can either choose to divorce by agreement or terminate the marriage by litigation. If both parties meet the substantive requirements of marriage after February 1, 1994, they are just cohabiting. If they just don't want to live together, they can separate. If there is a dispute over the custody of the child or the property and debt during the cohabitation period, the dispute can be settled in the court through litigation.
