Looking for an Oliver County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Sanger. What this Oliver County guide covers: how the atlas is organized, where to find editions, and how the county viewer fills the gaps.
The Oliver County plat book: start here
In and around Hannover, a plat book is a privately published atlas, that map ownership across the countryside, often organized by township.
Getting to the right map
Go first to the Oliver County Portico map; it maps every tax parcel in the county, Hannover included. If you're looking near Lake Sakakawea, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. In and around Hannover, save the parcel ID from that panel; every office in the county will want it.
When a parcel crosses a boundary
The county touches Burleigh County, McLean County, Mercer County, and Morton County, all with their own assessor records around Hannover. A tract near the line by Lake Sakakawea can be split across two assessors' files, so check the neighboring map too. For property near Hannover, our state page lists every neighboring county map across North Dakota.
Editions and availability
Not every county has a current edition, so ask at the courthouse, extension office or a local library near Price.
Using the parcel viewer instead
The Oliver County Portico map is updated more often than any atlas, including rural land around Hannover.
Sections, lots and bearings
North Dakota uses the Public Land Survey System, so deeds around Hensler reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Hensler odd-sized. Copy the legal description from the record for the parcel near Fort Clark for any title or survey request.
Why people still buy them
Buyers and seed dealers around Fort Clark rely on them to see ownership across many tracts at once.
Getting your bearings
Center serves as the county seat, where most land records are kept. You'll also find Fort Clark, Hannover, Hensler, and Price, where town lots give way to larger tracts. Roughly 1,879 people live in Oliver County (Census Bureau estimate, 2023) across roughly 722 square miles. Oliver County was organized in 1885, which matters when you trace an old farm's title. Features like Missouri River and Lake Sakakawea are easy to spot when you zoom out.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Sanger, but coverage can be spotty out of town. A screenshot of the parcel near Hensler with its ID is a good backup.
Plat book vs. recorded plat
For land near Price, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Recorder is a legal document, and the atlas is just a guide.
Before you lean on the lines
If you're looking near Center, the acreage figure is a tax-roll number; just a licensed surveyor establishes the real corners on the ground. For a home near Hensler, records update in batches, so a deed recorded last month can take weeks to appear.
The paper trail behind a parcel
Before you sign anything, get the recorded deed from the County Recorder; the parcel line is a drawing of it, which applies near Center as much as anywhere. For acreage around Fort Clark, inherited tracts in the county may trace back through several deeds, so a title company is worth hiring before a purchase.
Making your own township pages
Screenshot each section of the viewer around Hannover to build your own up-to-date atlas.
Who handles what
