Definition
In property law and surveying, monuments are fixed physical objects — natural or artificial — used to establish and identify the boundaries of a parcel of land. They serve as the on-the-ground reference points from which a legal description of property is interpreted and, when necessary, reconstructed.
Natural monuments include rivers, streams, springs, lakes, ridgelines, and other features of the physical landscape. Artificial monuments include marked trees, stakes, iron pins, stones, posts, concrete markers, and similar objects set in place by surveyors or grantors for the express purpose of marking boundary lines or corners.
In the law of land description, monuments occupy the highest tier of a traditional priority hierarchy: when a deed's calls conflict, monuments generally control over courses (compass bearings), distances, and area calculations. The reasoning is that a physical object on the ground reflects the parties' actual intent more reliably than a surveyor's measurement, which may have been imprecise.
Common Language
Modern common usage (Wiktionary): Plural of monument — large structures, statues, or constructions erected to commemorate a person, event, or period.
Historical common usage (Webster's 1913): Any structure, building, or erection intended to perpetuate the memory of a person or event; also, a stone or other marker placed to indicate a boundary.
The ordinary meaning centers on commemoration — memorials, statues, public structures. The legal meaning is narrower and more functional: a monument in property law need not be grand, visible, or permanent to human memory. A wooden post, a blazed tree, or a pile of stones qualifies. What matters is its role as a boundary marker, not its cultural or historical significance.
Core Elements
For a monument to control in boundary disputes, courts generally consider:
1. Identification — the monument must be identifiable on the ground with reasonable certainty, either by its continued physical presence or by credible evidence of its former location.
2. Intent — the monument must have been placed or recognized as a boundary marker at the time of the conveyance, not merely incidentally present on the landscape.
3. Permanence — while absolute permanence is not required, courts give less weight to temporary or easily moved markers. Natural monuments typically receive the highest weight because of their stability.
4. Hierarchy — when a deed contains conflicting calls, the traditional order of priority is: (1) natural monuments, (2) artificial monuments, (3) adjacent boundaries, (4) courses and bearings, (5) distances, (6) area.
Recognized Forms
/SUBTYPES
Natural monuments: Permanent features of the physical landscape not placed by human hand — rivers, streams, lakes, ridges, rock outcroppings, springs.
Artificial monuments: Objects placed by surveyors or grantors to mark boundaries — iron pins, concrete markers, stone bounds, stakes, posts, marked or blazed trees.
Called monuments: Objects explicitly referenced in a deed's legal description.
Parol monuments: Boundary markers established or identified by oral agreement or testimony, sometimes recognized to resolve ambiguity in written instruments.
Why It Matters in Research
The central research trap is the hierarchy rule. Researchers reading historical deeds — particularly pre-twentieth-century conveyances — will encounter descriptions that call for distances and bearings, but the monuments called in those same deeds may override those numbers entirely. A grantee who walked the stated distance due north and found nothing, while the actual corner post stood thirty feet to the east, would lose to the monument. Understanding this priority rule is essential to interpreting any early land description correctly.
A second trap: monuments perish. Trees die and are removed; wooden posts rot; iron pins are displaced by construction. Corpus sources frequently address the evidentiary question of what proof is sufficient to establish a monument's former location when the object itself is gone. This generates substantial litigation in boundary and ejectment cases throughout the nineteenth and early twentieth centuries.
Jurisdictional variation in how courts rank called monuments versus senior conveyances creates meaningful divergence across state case law. Researchers working across multiple jurisdictions should not assume the hierarchy is uniform. Some states modulate the rule when a monument is shown to have been erroneously placed.
For survey plat research, be alert to the distinction between monuments of record (those called in the deed) and monuments found in the field (those actually located by a resurveying party). These may not coincide, and the legal consequences of that gap are the subject of an extensive body of resurvey and boundary law.
Historical Dictionary Support
Both Black's and Bouvier's converge on the same core definition: permanent landmarks established to indicate boundaries. Bouvier's is more useful for research purposes because it explicitly distinguishes natural from artificial monuments and provides illustrative examples — marked trees, springs, rivers, corner posts, and clearings — with historical case citations. This reflects the practical concerns of nineteenth-century land law, when boundary disputes involving wild or recently surveyed territory were common.
Black's entry, as reproduced here, appears partially corrupted or conflated with another entry (the text veers into language about proceedings and claims of right that belongs to a different term, likely scire facias or a related remedy). Researchers relying on the Black's entry in isolation should cross-check with Bouvier's. This is a good example of a transcription or scanning artifact in the historical dictionary corpus that can mislead.
Neither historical dictionary addresses the priority hierarchy rule directly as a doctrinal statement — that synthesis emerges from case law rather than dictionary treatment. Researchers should treat the dictionary definitions as definitional anchors and look to treatises on real property and surveying for the operative legal rules.
Jurisdictional Note
The rule that monuments control over distances and courses is widely accepted but not universal in application. Western states operating under the public land survey system apply specific federal resurvey rules alongside state common law principles, which can affect how conflicting calls are resolved. Researchers should approach boundary disputes in public land states with awareness of both layers.
