When a deed near Marquand says lot and block, you'll need the Fredericktown plat map to make sense of it. This Fredericktown guide covers: where plats are filed, plat versus tax map, and what to look for on the sheet.
The Fredericktown plat map: start here
For land around Cobalt, the deed or parcel record often names the subdivision and plat reference; that makes the request quick.
The free map to start with
Parcels around Junction City can be looked up on the Madison County BreezeMaps viewer, free to use and open without a login. For land near Marquand, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. For acreage around Cobalt, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Where Fredericktown fits in
Fredericktown is part of Madison County, Missouri, which means parcel data comes from the county. Fredericktown is also the county seat, handy when you need recorded documents. For a home near Cobalt, City or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the city limits toward Junction City often falls under county rules instead.
Replats and vacations
Lots near Marquand can be combined or reconfigured by a replat, so check for later filings; street vacations near Junction City show up in the records too.
What the map can't tell you
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Cobalt can sit some distance off the line on screen. Near Cobalt, records update in batches, so a deed recorded last month might lag behind.
How a plat differs from the tax map
The Madison County BreezeMaps viewer draws parcels for taxes, but the recorded plat is what the deed relies on.
Sections, lots and bearings
Missouri uses the Public Land Survey System, which means a tract near Marquand is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Marquand can be irregular. Write down the legal description for the tract near Marquand for any title or survey request.
Reading the plat sheet
Near Cobalt, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Ordering the Fredericktown plat map
For acreage around Cobalt, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Marquand, so load it before you lose signal. A screenshot of the parcel near Cobalt with its ID keeps working without signal.
When a parcel crosses a boundary
Madison County meets Bollinger County, Iron County, Perry County, St. Francois County, and Wayne County, and each of those keeps its own parcel map. Ground near Marquand that runs to the line can be split across two assessors' files, so check the adjacent map before you assume the acreage. For a parcel near Marquand, the Platbookmapper state page lists each bordering county map for Missouri.
Getting your bearings
Fredericktown is the county seat, where most land records are kept. Smaller places on the map include Junction City, Cobalt, and Marquand. Roughly 12,698 people call Madison County home (Census estimate, 2023) on some 494 square miles. Madison County was organized in 1818, which matters when you trace an old farm's title. Features like Mark Twain National Forest are easy to spot when you zoom out from Marquand.
Offices that can help
Questions about value or the owner field for land near Cobalt are handled by the County Assessor, since that office keeps the assessment data. Questions about what you can build around Cobalt need the planning or permitting office, town or county, depending on location.
Metes and bounds instead
Acreage around Marquand outside a subdivision may have no plat at all; look for a recorded survey for land near Cobalt.
Recorded documents worth pulling
Before you sign anything, pull the recorded deed from the Recorder of Deeds; the parcel line is a drawing of it, and that holds around Cobalt too. Long-held tracts around Marquand can sit on many deeds, and a title company is worth hiring on a real sale.
