To identify possible encroachments, a buyer should insist upon

A plat is a graphical representation of land divisions and property boundaries, typically used in planning and zoning. While it offers a general layout of properties, it does not provide the precise measurements and detailed information needed to identify encroachments. Hence, it lacks the specificity required for a buyer concerned about property lines.

Title insurance protects buyers from losses due to defects in the title, such as liens or ownership disputes. However, it does not address physical property boundaries or identify encroachments. While it is a crucial aspect of securing ownership, it does not provide the necessary information regarding actual property lines.

A special warranty deed offers limited protection to the buyer, ensuring that the seller has not encumbered the property during their ownership. However, like title insurance, it does not provide information about the physical boundaries of the property or potential encroachments. Its focus is on the title rather than the land's dimensions.
