"Sheriff...how long would it be before they attached my paycheck???"
*** If the debt/judgment was included in your bankruptcy, they MIGHT have been noticed of your filing. The reason they MIGHT is that a no asset case does not get 'noticed' to creditors.
If they were noticed, then they cannot start attaching (garnishing) your wages at all.
And if they were not noticed, have your attorney contact them and put them on notice. When you filed, an automatic stay went into place with ALL creditors preventing them from taking any further collection actions.
