I am looking to file for bankruptcy to stop a garnishment. I also received a Motion to Enter a Wage Withholding Order from the same people.

An Earnings Withholding Order is a directive to your employer to withhold the required amount from your paycheck and send it to the judgment creditor.   Typically this is 25% of your net pay.  You can file bankruptcy anytime and it will stop any future garnishments, but you usually cannot get back what is already taken prior to filing your bankruptcy. Make sure you hire an experienced bankruptcy attorney to represent you.
