Boundary Surveying and Land Descriptions
This domain tests retracement doctrine and deed construction rather than original design: how Oklahoma surveyors weigh evidence, interpret calls, and resolve gaps and overlaps between adjoiners.
Hierarchy of boundary evidence
Oklahoma follows the common-law rule that original monuments control over courses, distances, and area. The practical order is: natural monuments, original artificial monuments (GLO corners, bearing trees, called-for pipes), subsequent monuments, courses and distances, then area. A called-for monument found undisturbed is strong evidence; an uncalled-for monument found by chance deserves scrutiny before it is accepted.
Reading a description
Metes and bounds begin at a point, run calls around the parcel, and return to the point of beginning; a description that does not close creates a gap or overlap to be resolved with adjoiner deeds and occupation. Aliquot calls ("the SW1/4 of the NE1/4") are construed within the PLSS. Where language is ambiguous, Oklahoma courts look for the grantor's intent from the whole instrument and surrounding circumstances; ambiguities are generally construed against the grantor, and area is the weakest call.
Worked example
A 1948 deed reads "...thence S 89°30' E 200.00 feet to a 1/2-inch iron pipe set in concrete." Your search finds the pipe undisturbed at 199.62 feet. The pipe controls: hold the pipe, record 199.62 feet, and continue from it. Do not set a new corner at 200.00 feet. If the pipe is not the monument called for, or shows disturbance, evaluate bearing trees, adjoiner deeds, and occupation before deciding.
Traps
Treating acreage as controlling; "correcting" or moving original monuments; assuming record bearings are true north when they were magnetic at the survey date; ignoring the adjoiner's deed; failing to close the description.
