There might be a internet system in your state for the NJ equivalent of the superior courts (of GA). But otherwise you will prolly need to go to your county courthouse and look up your name there. The Clerks office may be able to help you look yourself up. This would be the same courthouse/clerks office that handles mortgages, deeds, and plats.
I am sorry if this doesn't help but thats how it works in Georgia.
After a Google search it does look like you need to go to the Superior Court (and that is what NJ calls it, or so it seems) And i don't see a online system but i may have missed it. Usually they have a lien book or a computer database you can look through at the courthouse.
