What information is essential in a written property line boundary description?

A clearly stated basis of bearings is critical in a written property line boundary description because it establishes a reference direction that is used for delineating the boundaries of the property. The basis of bearings provides the framework for all measurements and angles defined in the description, ensuring consistency and accuracy in the representation of the property lines. It helps to eliminate ambiguity and allows other surveyors or individuals reviewing the boundary description to accurately understand and replicate the boundaries of the property based on a common reference. This precision is especially important in legal contexts where property boundaries may be contested or need to be clearly delineated for development or sales purposes. The other options do not provide the essential comprehensive guidance required for a complete boundary description, as simply indicating boundary lines, including personal details, or providing graphs alone does not convey the necessary context and direction that the basis of bearings supplies.
