Tax Lot Cards
Tax lot cards, which contain official descriptions of real property, are used to track land ownership and lot size and also may serve as a deed reference. Records include tax lot number; the location of the land in reference to township, range, and section; and a description and record of changes to the property, acreage, and land owner.
