  • Assigning tax parcel numbers to newly created parcels
  • Processing tax bills
  • Entering address changes for mailing tax bills as submitted by property owners or municipalities

Real Estate Sales

Various types of real estate documents recorded in the Walworth County Register of Deeds Office are linked by the Property Listing division to the applicable tax parcel identification number. The application entitled "Real Estate Sales Search" is available for viewing a list of those documents for a particular municipality. The results displayed cover a one-month period beginning with the date entered. While there are some earlier documents, the information primarily begins with documents recorded in 1973.

Real Estate Sales Search Instructions

  1. Go to the Real Estate Sales Search website
  2. Use the drop-down arrow to select a municipality. 
  3. Either enter a starting date with slashes between the day, month and year (i.e, January 1, 2000) or select the calendar to select a beginning date.
