If a surveyor disagrees with a previously established corner, what must they do before setting a new one?

Before a surveyor sets a new corner in disagreement with a previously established one, it is essential for them to verify that the previous corner is truly lost. This involves a thorough investigation of the existing evidence, which may include reviewing historical survey documents, physical evidence on the ground, witness testimonies, and any pertinent records that could confirm the position of the original corner.

By determining that the previous corner is indeed lost or mislocated, the surveyor ensures that they are acting within professional standards and legal guidelines. This step is vital because establishing a new corner without sufficient justification could lead to disputes, potential legal complications, and the loss of confidence in the surveyor's work. The process of verification serves to uphold the integrity of land surveying practices and maintains the accuracy of property boundaries.

The other options do not provide the necessary protocol for addressing a disagreement with an established boundary corner. Ignoring the previous assessment would undermine the importance of established records, while conducting a new survey without verifying the prior corner could lead to errors. Consulting with the property owner is important, but it does not replace the need for a methodical verification process regarding the corner in question.
