You don't have to do anything. However, you can contact the court on the "warrant" and let them know that the person does not live at your address. This, hopefully, would prevent a default judgment from being issued against a person who has not actually received notice.
While you are not REQUIRED to do anything, you can help out the justice system by notifying the court that the defendant on the WID does not live there..
A simple letter will do the trick--
Dear (name of court)
(defendant) does not live at the address, I do.
(your name and address)
