Legal analysis: The people's court can freeze the bank deposits of the executed person, which of course include the deposits on the credit card. But the credit card is the credit line given to you by the bank, not your private property. Therefore, the court will not freeze your credit card limit, but if the private funds beyond the limit are in the credit card account, the court can also freeze and deduct them.
legal basis: provisions of the Supreme People's Court on seizure, seizure and freezing of property in civil execution by people's courts
article 21 the seizure, seizure and freezing of the property of the person subjected to execution shall be limited to the amount sufficient to pay off the amount of creditor's rights and execution expenses determined by legal documents, and shall not be seized, seized or frozen if the amount obviously exceeds the standard. If it is found that the amount exceeding the bid is sealed up, detained or frozen, the people's court shall, upon the application of the person subjected to execution or ex officio, promptly release the sealed up, detained or frozen part of the property exceeding the bid, except that the property is inseparable and the person subjected to execution has no other property available for execution or other property is insufficient to pay off debts.
article 33 if a financial institution unfreezes the funds frozen by the people's court without authorization, and the frozen funds are transferred, the people's court has the right to order it to recover the transferred funds within a time limit. If it fails to recover within the time limit, it shall be ruled that the financial institution shall be liable to the applicant for enforcement with its own property within the scope of the transferred funds.
article 37 if the relevant unit pays the person subjected to execution or other people without authorization after receiving the notice from the people's court to assist in the execution of the income of the person subjected to execution, the people's court has the right to order it to recover within a time limit; If it fails to recover within the time limit, it shall be ruled that it shall be liable to the application executor within the amount paid.
