To identify possible encroachments, a buyer should insist upon

A plat is a map that shows the divisions of a piece of land, including lots, streets, and boundaries. While it provides an overview of property layout, it does not offer the precise measurements or detailed analysis necessary to identify encroachments accurately. A plat alone may not adequately highlight any potential issues related to boundary lines or neighboring properties.

Title insurance protects the buyer from future claims against the property title due to issues that may arise after the purchase, such as liens or ownership disputes. However, it does not address physical property boundaries or encroachments, making it insufficient for directly identifying potential property line issues before a purchase.

A special warranty deed conveys ownership and guarantees that the property was not encumbered during the seller's ownership but does not provide any information about the physical boundaries or potential encroachments. It is a legal document rather than a tool for assessing property lines, making it irrelevant for identifying potential encroachments.
