What is a public record containing official plats of subdivisions located in a county called?

A public record that contains official plats of subdivisions located within a county is referred to as a plat book. A plat book serves as a comprehensive reference that includes maps and diagrams delineating the boundaries, dimensions, and layouts of various parcels of land. This resource is crucial for property owners, developers, and legal professionals as it provides clear graphical representations of land divisions, aiding in understanding property limits and zoning issues.

In contrast, a land register typically pertains to a database or system used for recording land ownership and property rights but may not specifically include the detailed maps found in a plat book. A survey book usually contains records and results of land surveys, which may not be organized in the same format as the plats in a plat book. Similarly, a property ledger is more focused on inventorying property transactions or ownership details rather than providing graphical representations of land designs.
