If the credit card company chooses, it can stop the garnishment from proceeding. It sounds like it has made its choice to proceed.
The subject of the garnishment (the "garnishee") can object to the garnishment on a number of grounds including:
* Objecting that the garnishment proceedings are somehow defective, or that the property at issue is legally exempt from garnishment;
* Filing bankruptcy, and reporting the bankruptcy to the court;
* There is an existing, valid court order governing repayment, for example allowing installments, and the garnishment action is not consistent with that order.
* The garnishment (particularly a garnishment of wages) exceeds the limits permitted by law, whether alone or in conjunction with other garnishments with higher priority.
* The underlying debt has been paid. (This means proving actual payment, not attempting to challenge the validity of the underlying judgment.)
