Which aspect of title insurance helps to define property boundaries?

The metes and bounds description is the correct choice as it specifically refers to a system used to define the boundaries of a particular parcel of land. This method relies on detailed descriptions that often include physical features of the geography (like trees, rivers, or roads) and measurements (such as distances and angles) to outline the exact perimeter of a property. This makes it crucial for determining property lines, which is essential for both ownership and development purposes.

In contrast, an abstract of title provides a summary of all recorded documents related to a property, but it does not directly detail the boundaries. A title search involves examining these documents to confirm ownership and any encumbrances but is more focused on ownership history rather than delineating property lines. Lastly, a public records review refers to examining various public documents, which may include title documents and land use regulations, but does not focus specifically on the boundaries themselves. Thus, the metes and bounds description stands out for its specific role in identifying and defining property boundaries accurately.
