Land Boundary Surveying and Legal Principles
What this domain tests
This domain tests whether you can separate boundary location from measurement precision. A retracement survey recovers the intent of the original conveyance from evidence; it does not create a new boundary or decide title.
Core rules
- Follow the evidence hierarchy, but weigh quality: natural monuments, artificial monuments, courses and distances, then area. An original, undisturbed monument generally prevails over a deed distance.
- Identify the original survey and its corners. Do not “correct” an original PLSS corner to make record distances close.
- Possession lines, acquiescence, estoppel, and adverse possession may affect title; the surveyor documents them and lets counsel advise on legal effect.
- For water boundaries, meander lines are not the boundary. Locate the ordinary high water mark and distinguish accretion from avulsion.
Worked example
A deed reads “thence N 0°00′ E 200.00 ft to a found 5/8-inch rebar.” The rebar is found at 198.6 ft, and its age and accessories support it as the called-for monument. Accept the pin as the terminus; do not move it to 200.00 ft. The distance is evidence, not the controlling call. If the pin were a newly set, unexplained stake, it would carry little weight.
Traps
Holding deed distance over a called-for monument; treating GNSS coordinates as the boundary; ignoring occupation lines; assuming a meander line is a water boundary; and presenting a survey as a court adjudication.
