The Decatur plat map: start here
For a lot near Hartselle, the deed usually cites the plat; use it to request a copy.
The viewer Morgan County publishes
Go first to the Morgan County parcel viewer; it includes every tax parcel around Priceville and Trinity. Out toward Hartselle, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Falkville, the record panel typically gives the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Places you'll see on the map
Decatur holds the county offices, which is where the courthouse records live. You'll also find Trinity, Priceville, Hartselle, and Somerville, each with its own cluster of lots. About 125,133 people call Morgan County home (Census Bureau estimate, 2023) across some 580 square miles. Morgan County was formed in 1818, and some chains of title near Falkville are long. Features like Wheeler National Wildlife Refuge are easy to spot when you zoom out from Huntsville.
Who handles what
For assessment questions about property around Priceville go to the revenue commissioner or tax assessor, the office behind the parcel record. Building or septic questions for a lot near Trinity need the planning or permitting office, town or county, depending on location.
Legal descriptions in Alabama
Alabama uses the Public Land Survey System, which means a tract near Trinity is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Trinity can be irregular. Write down the legal description for the tract near Hartselle before you request a deed or survey.
Land on the county line
Morgan County meets Cullman County, Lawrence County, Limestone County, Madison County, and Marshall County, and each of those keeps its own parcel map. A tract near the line by Falkville may show up across two assessors' files, so look at the adjacent map before you assume the acreage. In and around Trinity, our state page links each bordering county map for Alabama.
Where Decatur fits in
The city lies within Morgan County, Alabama, so its parcels are on the county's map, especially near Hartselle. Decatur is also the county seat, which puts the Judge of Probate (probate office) close by. On ground around Trinity, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Land beyond the town limits near Priceville generally follows county rules rather than the town's.
What the map can't tell you
The acreage figure is an estimate; only a licensed surveyor sets the real corners for a parcel near Trinity. For property near Somerville, records update in batches, so a deed recorded last month might lag behind.
Recorded plat or GIS layer
The tax map on the Morgan County parcel viewer is a summary, while the recorded plat is the legal document.
When a plat changes
Lots near Priceville can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations near Huntsville show up in the records too.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Hartselle sit with the Judge of Probate (probate office). Long-held tracts near Falkville may sit on a long string of deeds, and a title company can sort it out on a real sale.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Trinity, but coverage can be spotty out of town. A saved image of the lot near Priceville and its lines helps when you meet an owner or agent.
Reading the plat sheet
Recorded easements around Somerville can block a shed or pool; read the notes on the sheet.
Online indexes and office visits
Near Somerville, many recorder offices offer an online index, while others require a visit or a request; small fees are common.
When there's no plat
Acreage around Hartselle outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
