Tracking down tenant for back due rent NJ

[Alexander D Marchena]

I have a unit that I now have legal possession of (legal term for NJ) the tenant moved out owing $3200 in back rent and fees.

I had filed for eviction when I explained the situation to the court I was told to cancel the complaint and track him down and sue in the state/county he now resides in.

How the heck do I do this I check social media/post office won’t provide his forwarding address.

What steps have you guys taken?
