The husband's overdue car loan will not affect his wife's credit information. The bank's credit information is a personal credit information, not a family credit information. If it is a company loan or your personal loan, it will not be affected. However, if it involves housing or family consumption loans, it will be affected because it is necessary to check the spouse's credit information. According to the relevant regulations, the debts incurred by one spouse before marriage belong to personal debts in principle, and are repaid within the limits of personal property; The debts established during the marriage relationship are joint debts of husband and wife, which are repaid by the joint property of husband and wife. Therefore, during the marriage, the loan to the bank is the joint debt of the husband and wife, and the property also belongs to the joint property of the husband and wife.

The measures for being sued for defaulting on loans are as follows:

1. If the court has not pronounced a judgment, the borrower can take the time to negotiate with the defaulting institution and try to get the other party to withdraw the lawsuit;

2. If you have the ability and don't return it, the court will enforce it;

If you can't afford it, you can apply for deferred repayment or partial interest reduction.

Legal basis: Article 1064 of the Civil Code of People's Republic of China (PRC).

Debts jointly signed by husband and wife or ratified by one party afterwards, as well as debts incurred by one party in his own name for the daily needs of the family during the marriage relationship, belong to the joint debts of husband and wife. The debts incurred by one of the husband and wife during the marriage relationship in their own name beyond the daily needs of the family are not joint debts of the husband and wife; However, the creditor can prove that the debt is used for the husband and wife's common life, joint production and operation, or based on the common meaning of both husband and wife.
