Can a credit card company garnish your checking account?

I am a lawyer in CT and practice in this area of the law.  A creditor may NOT garnish wages without a court order/judgment.  if the court dismissed the creditor's case, the creditor must refile it before moving to garnisih wages.  i suggest that you hire a lawyer to obtain the documents the creditor filed in court and then look inbto filing a unfair debt collection practices claim against the creditor.  your bank should not honor the garnishment without an order and I would be surprised that it permited the garnishment.  Indeed, the bank can be held liable for permitting the garnishment wihtout the right documents.  Hire a lawyer asap.
