Getting your bearings

A word on accuracy
Listed acreage is an estimate; just a licensed surveyor can set the real lines on land around Walworth. In and around Darien, records update in batches, so a deed recorded last month can take weeks to appear.
Tax data in the record
The record for a parcel near Fontana-on-Geneva Lake often lists value and tax amounts; the county real property listing office sets values and the treasurer or collector bills taxes.
Backing up the map with records
Before you sign anything, pull the recorded deed through the Register of Deeds; the parcel map near Sharon only summarizes it. For property near Fontana-on-Geneva Lake, have ready the book and page listed on the parcel record to skip a name search.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Elkhorn, though signal can drop in rural spots. A saved image of the lot near Walworth and its lines helps when you meet an owner or agent.
Where Delavan fits in
Delavan is part of Walworth County, Wisconsin, and the county assessor maps its lots. In and around Walworth, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits toward Elkhorn often answers to county rules instead.
Reading the owner field
In and around Walworth, the owner field shows who the tax bill names, which may be a person, a trust, a company or an estate. "Estate of" on a record near Darien usually means title hasn't passed yet after a death, so the personal representative is the contact.
Getting answers from the right desk
For assessment questions about property around Williams Bay belong with the county real property listing office, the office behind the parcel record. Building or septic questions for a lot near Elkhorn are for the local planning and health departments, and the answer depends on jurisdiction.
Sections, lots and bearings
Wisconsin follows the Public Land Survey System, so deeds around Elkhorn 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 Darien odd-sized. Copy the legal description from the record for the parcel near Elkhorn for any title or survey request.
When you need more than the map
Bring the document number shown for the parcel near Walworth to find the deed quickly; hire a title company before money changes hands.
Looking around the parcel
