New Jersey deeds trace boundaries by bearing and distance, often from one old marker to the next. Corner pins, a recorded plat and a New Jersey licensed surveyor beat any line on a screen.

- Line up the assessed land values of a few neighboring tracts near Belvidere to sanity-check an asking price.
- Before you sign for land near Belvidere, check what the local planning and health offices will allow on it.
Where Warren County deeds and plats are kept
