NJ-Suing Landlord for rental deposit but cant find any info on him.

Hi, me and my roommate went to court to obtain our rental deposit. Just to note on the lease the rental office is based in New York and we dont have any information regarding the slumlord name, phone number or address. When we put in maintenance requests as well it seems like he hired third party companies to take our calls and they would never be able to get in contact with him as well. Back to current date, the judge ruled in our favor and said that the slumlord have to give us double the rental deposit. The judge gave us an "Order of Judgement after Proof Hearing" and told us to serve it to him. We served it to the address that was on our lease, sadly it wasn't his address it was a a post office with p.o boxes in a jewish town in new york. We served the paper to the p.o box and pretty much didnt do nothing afterwards. I was pretty much the only one doing the leg work and got occupied with life and trying to find a place to stay. Now Im contacting Newark courthouse to see what else we can do, they told me to fill out a Writ and said that we dont need the lanlord banking info but when we got there they said we either need property info or banking info which we dont have. When I searched up the rental company name it's a dead-end and I dont get specific names on who own the property. What should I do next? I even texted the maintenance guy but I doubt he will give us any info. Im in my early 20s this was my first apartment and we were desperate, living under this landlord was hell there was even a monoxide leak in the apartment and people could have literally died, the fire dept came that day and told everyone we couldn't stay in the apt that night but we just want our rental deposit back. How should we proceed and should I get a lawyer?
