Are the Belknap County property lines accurate?

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

The office title varies by state (register of deeds, recorder, county clerk or clerk of court), so check the Belknap County government website for the right one. For subdivision lots in Laconia, the plat book and page on the record leads straight to the recorded plat.
