If you don't know who spent the money in the credit card, you can go to the bank to check the consumption records. Online banking can be used: after the user enters my account, he can log in to online banking to check the transaction details. When a person dies, the expenses in the credit card need to be paid off by the heir. If there is no heir, the debt will naturally die out and the loan can no longer be recovered. However, if this debt belongs to the joint debt of husband and wife, the bank can also require the spouse to fulfill the repayment obligation according to the regulations.
