Filing Chapter 7 or Chapter 13 enacts an automatic stay, which means that creditors are not allowed to take any further action against you to collect the debt owed to them.  This includes wage garnishments.  If your wages are being garnished at the time you file bankruptcy, you can contact both the creditor garnishing your wages, and your employer, to notify them that you have filed bankruptcy.  Once notified, they are required by law to cease the garnishment action.  The automatic stay, however, does not apply to child support and alimony garnishments.
