Legal analysis: husbands speculate in futures, but wives don't have to pay their debts. Because the debt of husband's speculation in futures is not used for husband and wife's life, it belongs to personal debt, and the wife does not have to repay it. If the husband and wife are in the same debt, the wife needs to bear the responsibility for repayment. If it is the husband's personal debt, the wife is not responsible for repayment. At the time of divorce, the debts owed by the husband and wife living together shall be paid jointly. * * * If the same property is not paid off, or the property belongs to the other party, both parties agree to repay it; If the agreement fails, the people's court shall make a judgment.
