Hunting for the latest Montgomery County plat book? A plat book shows owners and tract lines on township pages, useful for farms near Freysbush. Covered here for Montgomery County: what's in a plat book, where to find editions, and the free online map that stays current.
Getting started with the Montgomery County plat book
If the land is near Fonda, a plat book is a privately published atlas, showing rural owners and tract lines, often organized by township.
Opening the official parcel viewer
Property in and around Auriesville are published on the NYS Tax Parcels Public layer in ArcGIS Map Viewer, a viewer that needs no account. Out toward Auriesville, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. For acreage around Florida, save the parcel ID while you have it open; every office in the county will want it.
Neighboring parcel maps
Montgomery County meets Fulton County, Herkimer County, Otsego County, Saratoga County, and Schenectady County, all with their own assessor records. Acreage along the edge near Amsterdam may show up in two county records, so open the neighboring map too. For property near Charleston, the Platbookmapper state page lists every bordering county map for New York.
Buying or borrowing a copy
Not every county has a current edition, try the county extension office, recorder's office or library near Sprakers.
Sections, lots and bearings
Tracts outside towns near Fort Hunter are often described by metes and bounds, which trace the boundary call by call. Town lots near Minden are typically described by lot and block, which is simpler to follow. Write down the legal description for the tract near Amsterdam when you talk to a surveyor.
What the map can't tell you
For a parcel near Freysbush, acreage on the record is an assessed number; only a licensed surveyor establishes the real boundary on the ground. For a tract near Freysbush, owner names and values update on a schedule, so a deed recorded last month might lag behind.
The free online alternative
Between printed editions, the NYS Tax Parcels Public layer in ArcGIS Map Viewer shows current owners, including rural land around Charleston.
Not the same thing
On ground around Auriesville, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Clerk is a legal document, while the atlas is a reference.
Printing your own
Print parcel views near Freysbush township by township to build your own up-to-date atlas.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Fonda, so load it before you lose signal. A screenshot of the parcel near Florida with its ID keeps working without signal.
Which office to call
For assessment questions about property around Minaville are handled by the county Real Property Tax Services office, the office behind the parcel record. Questions about what you can build around Fonda go to planning, building or health offices, town or county, depending on location.
Why people still buy them
Farmers, hunters and appraisers near Fort Hunter use plat books for a big-picture view of who owns what.
Backing up the map with records
If you're looking near Charleston, the map is an index, not the title: deeds, plats and easements for parcels in the county sit with the County Clerk. For a tract near Fort Hunter, bring the book and page shown in the record panel and the lookup takes minutes.
Getting your bearings
Fonda holds the county offices, which is where the courthouse records live. You'll also find Amsterdam, Canajoharie, Charleston, and Florida. Around 49,368 people call Montgomery County home (Census Bureau estimate, 2023) on about 403 square miles. Montgomery County was organized in 1772, so old deeds can run back a long way.
