Looking for a Johnson County plat book? A plat book shows owners and tract lines on township pages, useful for farms near Princes Lakes. Covered here for Johnson County: what's in a plat book, where to find editions, and the free online map that stays current.
Getting started with the Johnson County plat book
For land near New Whiteland, plat books are commercial atlases, with owner names on each tract, often organized by township.
Opening the official parcel viewer
The official parcel map for this area is the Johnson County Beacon site, and anyone can open it without signing up. When a rural tract has no street number, follow the nearest road on the aerial and click the parcel itself, for land near Princes Lakes included. For acreage around Bargersville, copy the parcel ID from that panel; every records desk in the county will want it.
Next door to Johnson County
The county touches Bartholomew County, Brown County, Marion County, Morgan County, and Shelby County, and each of those keeps its own parcel map, at least around Trafalgar. Ground near Greenwood that runs to the line can be split across two assessors' files, so check the neighboring map before you assume the acreage. In and around New Whiteland, the Platbookmapper state page links each bordering county map across Indiana.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Bargersville, so load it before you lose signal. A printout of the tract near Franklin is a good backup.
What the map can't tell you
For a tract near Edinburgh, acreage on the record is a tax-roll number; only a licensed surveyor sets the real lines on the ground. Owner names and values update on a schedule, so a fresh transfer around Franklin may not show yet.
Getting answers from the right desk
Anything recorded against property around Bargersville sit in the index kept by the County Recorder, often with an online index. Building or septic questions for a lot near Bargersville are for the local planning and health departments, town or county, depending on location.
Who uses plat books
Buyers and seed dealers around Princes Lakes rely on them for a big-picture view of who owns what.
Deeds, plats and who keeps them
Near Edinburgh, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are filed with the County Recorder. Long-held tracts near New Whiteland can trace back through many deeds, and a title company earns its fee if money is changing hands.
Where to look for one
Not every county has a current edition, try the county extension office, recorder's office or library near Princes Lakes.
Getting your bearings
Franklin holds the county offices, which is where the courthouse records live. You'll also find Bargersville, Edinburgh, Greenwood, and New Whiteland, where town lots give way to larger tracts. About 167,819 people call Johnson County home (Census estimate, 2023) across roughly 320 square miles. The county dates to 1823, and some chains of title near Princes Lakes are long.

Sections, lots and bearings
Indiana is laid out under the Public Land Survey System, which means a tract near Edinburgh 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 corrections make some sections near Edinburgh odd-sized. Keep the legal description for land near Bargersville before you request a deed or survey.
Plat book vs. recorded plat
For acreage around Princes Lakes, 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.
