After getting married, if the other party takes out a loan without the knowledge of one party, it is generally a joint debt of the husband and wife. If the debt is not repaid, the creditor will sue the husband and wife and require both parties to repay the debt.
The condition for determining whether it is a joint debt between husband and wife is not whether the other party knows about it, but whether one party borrows money for family life.
As long as it is used for family life, regardless of whether the other party knows it or not, it is a joint debt of the husband and wife.
Article 2 of the "Interpretation of the Supreme People's Court on Issues Concerning the Application of Law in the Trial of Cases Involving Debt Disputes between Spouses" stipulates: Debts borne by one spouse in his or her own name for the daily needs of the family during the marriage, If a creditor claims rights on the grounds that the debt belongs to the same husband and wife, the People's Court shall support it.
