DENR Administrative Order (DAO) 2007-29 Practice Test

The essential idea is that a survey’s authority must be grounded in a legal basis. To support jurisdiction, the survey returns should attach documents that establish who has the right to conduct the survey and what land is involved. A copy of pertinent laws, legal documents, or muniment of title provides that foundation—showing the official authority to survey and the recognized ownership or status of the land. Without this legal basis, the survey could be challenged on who has jurisdiction or what land is being described. Photographs may illustrate conditions but don’t prove who has the legal authority or the rightful property boundaries. A map of the property is part of the survey product but does not by itself establish jurisdiction; it describes the area rather than proving the authority or ownership. A list of surveyors is administrative and confirms who carried out the work, not the legal basis for the survey.
