The Montgomery County plat book turns a drive past an empty field near Hillsboro into a name, a parcel number and an acreage figure.
This guide walks through the official link, the kinds of land you'll find around Hillsboro, and what to do when the map and the ground don't agree.
Where to open the official Montgomery County plat book
The Montgomery County Beacon site is the county's own public parcel viewer; it runs on Schneider Geospatial's Beacon platform. For a tract near Nokomis, the report page lists sales history and the legal description, and a map link zooms straight to it. Bookmark the Platbookmapper page for Montgomery County too; we update it when the official map moves.
Is there a current Montgomery County plat book?
Farmers, hunters and rural mail carriers around Hillsboro have long used printed plat books, which show each township with owner names written on the tracts. The catch is age. A printed book is a snapshot from the year it was compiled, while the online Montgomery County parcel map is updated as deeds are processed.

How to find property lines in Montgomery County
On rural tracts near Zanesville, the parcel lines can drift from the fences on the ground, sometimes by more than a few feet. The section grid shapes many farm tracts around Zanesville; boundaries often follow quarter-section lines you can spot on the map. If a neighbor's fence near Nokomis and the map disagree, neither one is proof. A survey is.
Where Montgomery County deeds and plats are kept
For land near Coffeen, the parcel record is the index; the recorded deed is the source. Check the county government website to see which office records deeds for land near Zanesville.
