1.2 Legal Evidence Framework
Key Takeaways
- Boundary resolution starts with intent and evidence, not with forcing record bearings, distances, or area to close mathematically.
- A reliable original monument or called-for monument commonly carries more weight than conflicting course, distance, or area calls.
- Senior rights usually control before junior rights in sequential conveyances, but reservations, exceptions, statutes, and facts must still be checked.
- Water boundaries require careful distinction among riparian and littoral rights, navigability, gradual accretion or reliction, and sudden avulsion.
- PLSS corner status drives the method: recover an existent corner, restore an obliterated corner from evidence, and proportion a truly lost corner only when evidence is insufficient.
Evidence before arithmetic
The Legal Principles domain tests boundary judgment. A surveyor is not just computing a closed polygon; the surveyor is evaluating intent, records, physical evidence, occupation, and applicable law to form a defensible boundary opinion.
A useful exam habit is to ask three questions before doing math:
- What created the boundary? Look for the deed, plat, grant, survey, subdivision action, or other source of original intent.
- What evidence survives? Separate original monuments, called-for objects, adjoiner calls, occupation evidence, later measurements, and replacement markers.
- What rule controls the conflict? Use general evidence priority, senior rights, PLSS restoration rules, or water-boundary principles as the prompt requires.
Calls and evidence priority
A call is a descriptive element in a conveyance or survey record. It may call for a monument, an adjoiner, a course, a distance, an area, or another controlling object. When calls conflict, the exam usually rewards evidence that best reflects original intent.
| Evidence item | Typical exam treatment |
|---|---|
| Original monument | Strong evidence when genuine, undisturbed, and tied to the creating survey |
| Called-for monument or adjoiner | Can control because the record points to a real object or neighboring boundary |
| Course | Bearing or direction; useful but vulnerable to record or measurement error |
| Distance | Useful for geometry, but often secondary to reliable monuments and intent |
| Area | Usually the weakest call when it conflicts with better boundary evidence |
This is not a mechanical hierarchy that overrides every fact. State law varies, and a prompt may give statutory language, reservation language, or facts that change the analysis. Still, if an undisturbed original monument conflicts with a calculated distance or stated acreage, do not discard the monument just to make the numbers look cleaner.
Senior and junior rights
In sequential conveyances, an earlier valid conveyance is generally senior to a later one. A common grantor cannot usually convey the same land twice; a later junior deed receives only what remains unless the record and governing law say otherwise.
For exam purposes, shortages and overlaps often turn on sequence. The surveyor should trace the chain of title, inspect exceptions and reservations, compare adjoiner descriptions, and document the conflict. The surveyor identifies evidence and forms a boundary opinion; courts decide title disputes.
Water boundaries
Water boundaries add another layer because the boundary may respond to natural change. Riparian rights relate to rivers or streams, while littoral rights relate to lakes, seas, or oceans. Navigability and sovereign ownership can change the result.
The basic contrast is gradual versus sudden change:
- Accretion is gradual natural buildup and can move a water boundary under common principles.
- Reliction is gradual exposure of land as water recedes and can have similar boundary effects.
- Avulsion is sudden change, such as a flood cutting a new channel, and commonly leaves the legal boundary where it was before the event.
State law and the specific water body matter. On the PS exam, answer from the facts supplied and avoid importing a local shoreline rule that the question does not give.
PLSS corner status
For Public Land Survey System work, corner status controls the next step:
| Corner status | Meaning | Proper response |
|---|---|---|
| Existent | The original corner or acceptable direct evidence is found | Recover and use it, after verifying reliability |
| Obliterated | The monument is gone, but collateral evidence proves the original position | Restore the position from the evidence |
| Lost | Evidence is insufficient to identify the original position | Reestablish by approved proportionate methods |
The exam trap is replacing evidence with coordinates too quickly. A GIS point, protracted map location, or neat proportion is not superior to reliable original or collateral evidence. Recover first, restore from evidence second, and use proportion only when the corner is truly lost.
A deed calls to an original stone corner, then gives a course and distance that would place the line several feet away. The stone is found, undisturbed, and consistent with adjoiner evidence. What is the best exam response?
In a PLSS retracement, the original monument is gone, but witness trees, old field notes, and long-recognized occupation evidence allow the surveyor to identify the original corner position. How should the corner usually be classified?
