Unless a creditor of a person has an actual judgment or an authroization signed by the debtor allowing the withdrawal of money out of a bank account the creditor legally cannot get access to money in one's bank account.In your situation, if there is a judgment against you stemming from a lawsuit, the judgment creditor can levy upon your bank account to get moneys to pay down the judgment. If there is no judgment against you, then getting money from your bank account does not seem warranted based upon what you have written. I suggest that you consult with a debt collection attorney.
