Defendants do not have to move until 30 days AFTER the Judge confirms the sheriff's sale. I don't know what the Notice of Sale says that you are referring to but it is always 30-60 after confirmation that you must move or face an eviction action by the sheriff.
You have an attorney on the action - recommend you consult him or her for details.

Your attorney is correct. Pursuant to Illinois law, you have a minimum of 30 days to move out from the date of entry of the order confirming sale. Since your hearing is on 2/8/2013, you will have 30 additional days to remain in the home (assuming the order is entered). I believe the applicable statute is 735 ILCS 5/15-1701. Trust your lawyer; it sounds like he knows what he is doing.
