The Registry of Deeds is the office that processes information as it relates to the selling and buying of real property. It is a public office open to the legal profession and general public for researching the records. In addition to deeds, mortgages, liens and attachments, there are many other types of documents pertaining to land records filed with the Registry, for example, trustee certificates, power of attorney, plans etc.

The recording of important documents is one of the oldest functions performed by government. Centuries before the birth of Christ, the practice of stamping an official seal on documents was common.

The office provides information to 43 communities in Coos County (1 City – 19 Towns & 23 unincorporated places) There is a great deal of information available in the early volumes and anyone interested in genealogy may find it useful to research the records. The official records, maintained at this location, are dated from 1771.

Coos County (pronounced “CO-ahss” with two syllables), named for the indian word for pines, encompasses the entire northern section of the state, covering 1,804 square miles, 20% of the land area of the state of New Hampshire. The Abenaki word, also spelled cowass, cohoss, and coo-ash, was used to identify inhabitants of the region. The first reference to the area is found in the 1704 records of NH, which names the area “Cohoss” a large and valuable tract of land along the Connecticut River. The county is large in area – 1,855 square miles – but the most sparsely populated in the state with only about 35,000 people.

Coos County was separated from the northern part of Grafton County, New Hampshire and organized at Berlin in 1803, although, the county seat was later moved to Lancaster. The county includes the northern portion of the White Mountains, including all the summits of the Presidential Range, the most prominent of which is Mount Washington, the highest peak in New England and the Mid-Atlantic states.

Additional information on Coos County history can be found on the web pages at the University of New Hampshire (
