I Won a forclose case in supreme court,we had already came out of 2nd appellate court. now the attorney is using another address of my clients

It sounds as though you've been proceeding pro se, yet you make reference to your "clients"- are you an attorney? Definitely need more information here. It also sounds like you are in the middle of an appeal, or a motion for leave to appeal, so I suggest you respond quickly, because the clock is likely ticking on deadlines.
