The minute a bankruptcy case is filed the automatic stay is issued which prohibits creditors from trying to collect on debts that were included in the bankruptcy.
The automatic stay is self-executing, effective upon the filing of the bankruptcy case and requires that all collection calls, lawsuits and garnishments must stop immediately.
Creditors who continue with collection efforts face stiff fines and penalties from the bankruptcy court.
Section 362(k) of the Bankruptcy Code provides:
An individual injured by any willful violation of a stay provided by this section shall recover actual damages, including costs and attorneys’ fees, and, in appropriate circumstances, may recover punitive damages.
You may even be able to recover some of your wages lost to garnishment. Your wages can only be protected up to a certain amount, so you likely won’t be able to recover all of your losses that occurred due to garnishment.
