I am in a custody battle and have not received paperwork regarding meeting the guardian ad litum and court social worker. And court is on the 13th

You can track the progression of your case by going to the Wisconsin circuit court access site, including what the court hearing on the 13th is schduled for. You don't indicate in your post where you are in the proceedings. The court date very well may be a status date to check in with the court on where you are with  the case. The WI circuit court access site will also provide you the information on the name of the guardian ad litem and you can call the GAL's office on your own to find out when they may want to see you to discuss the case.
