1. In judicial practice, one spouse divorces by means of fake divorce, and then all the property belongs to the other spouse, which makes it difficult to realize the interests of legitimate creditors. Because this situation is relatively common, the Supreme People's Court's judicial interpretation stipulates that all legal debts during the existence of husband-wife relationship are joint debts of husband and wife, and both husband and wife bear the same burden;

As long as your parents are not divorced, the legal debts borrowed before the divorce are shared by both husband and wife (not equally shared). If the debt is really not used for family life, when the husband and wife divorce, the debt should be borne by your father and still shared by the husband and wife.
