Recording Subdivision and Site Plans

What is the Plat Law?

The recording of plats is governed by NH RSA 478:1-a under the Registers of Deeds and is generally referred to as the

Plat Law. A ‘plat’ is defined as a map of a specific land area whose boundaries are defined by metes and bounds.

A plat may show:

1. Newly created parcels, streets, alleys and easements as in a subdivision; or

2. A lot-line adjustment or site plan depicting existing parcels defined by legal descriptions contained in deeds, grants or other legal documents.

The standards of the Plat Law are designed to ensure that all plats or plans recorded at the state’s 10 registry of deeds are clear and reproducible. The Registry’s responsibility is to keep a record of information which defines the limits or extent of legal rights or interest in land. Construction plans, construction details and maps that do not define the limits or extent of legal rights or interest in land shall not be recorded per the plat law.

 Do’s and Don’t of Recording
