A seller’s pin or map image does not establish that fences and occupied areas match the recorded boundary.
The Department of Lands provides boundary-survey procedures involving records and adjoining landowners. An app measurement is not a substitute for that process.
Practical checks: compare site conditions with records and boundary markers. Where uncertain, ask the land office about a survey; do not move markers or take over disputed ground yourself.
