Can a surveyor seal a plat that was prepared by another firm?

The chosen answer indicates that a surveyor cannot seal a plat prepared by another firm due to a plan stamping violation. In order to maintain the integrity and accuracy of surveys, ethical and professional standards require that only the surveyor who has direct involvement in the preparation and verification of the work can affix their seal to that document. Sealing a document implies responsibility for its accuracy and compliance with professional standards, which would not be possible if the surveyor did not directly engage in its preparation.

Each of the other options presents scenarios where it might seem that sealing could be permissible under certain conditions. However, they all overlook the crucial professional ethics and regulations that are firmly established in land surveying practices. Hence, the requirement is clear: the surveyor must have directly prepared or supervised the work to be able to seal it legally and ethically.
