You've been "superpoked" _ and served. An attorney in Australia has used the popular networking Web site Facebook to notify a couple that they lost their home after defaulting on a loan. The Australian Capital Territory Supreme Court last Friday approved lawyer Mark McCormack's application to use Facebook to serve the legally binding documents after several failed attempts to contact the couple at the house and by e-mail. Australian courts have given permission in the past for people to be served via e-mail and text messages when it was not possible to serve them in person. The lender's application to take back the house in the capital, Canberra, was approved on Oct. 3 after the couple failed to appear in court. The lender was then required to serve the so-called default judgment on the couple before it could seize the property.
