The timing of the garnishment order and the issuance of the payroll check could be the answer to what happened here and would have an effect on the answer to this question.  Let's start by establishing a basic rule: it is never proper to knowingly violate a court order.  That being said, in certain states the order goes in to effect 30 days after it is issued.  That could mean that this is your last paycheck before the 90 day freeze.  It could also mean that your employer made a huge mistake on their part.  I would seek help with all of this, including the judgment and the garnishment.  Go and see a debt counselor that can help you with the matter.  Garnishment can be a huge chunk of your pay and you do not want to be left with nothing to pay the other bills in your life.  See if a deal can be worked out.  Good luck.
