In new jersey I've received a default judgment against me in the amount of $159,000 but I haven't received any documentation prior to being served.

In Aug 2013 my mother and I had an argument over money before I left for work. Later that evening officers were sent to my job to serve a restraining order, in shock I used profanity and was tackled to the ground by 4 officers and arrested, given a ticket and dropped back off at work. The case for the restraining order was dismissed because in the judges words "it was a waste of her time". The resisting arrest case was dismissed as well. In November 2013 I received a letter saying that 2 of the 4 officers injured themselves while voluntarily using force to arrest me, and that I owed them a total of $60,000 and I then consulted the ACLU of NJ and was told that the litigation was illegal for no probable cause and that I should not have anything to worry about. Last week I was served by a legal process courier with a default judgment form in the amount of $159,000. I'm scared and don't know what to do. I have the surveillance footage that will clear my name and prove my innocence.
