Definition
In surveying and conveyancing, "lines and corners" refers collectively to the boundary lines of a parcel of land and the terminal points or angles where those boundary lines meet or change direction. A line is the boundary segment itself — the course run between two fixed points. A corner is the point at which two boundary lines meet, forming an angle, or where a single line terminates and the next begins.
Together, lines and corners constitute the geometric skeleton of a land description. A deed or survey that calls for lines and corners is describing not just the perimeter of a tract but the specific directional courses and angular turning points that define its shape and extent on the ground.
Common Confusion
"Lines and corners" is sometimes loosely used as a synonym for "metes and bounds," but the two are not identical. Metes and bounds is the system of land description as a whole, incorporating distances, directions, monuments, and natural features. Lines and corners are the geometric components within that system — the courses and the points where courses change. A metes-and-bounds description uses lines and corners; the phrase "lines and corners" isolates those two structural elements and appears most often in disputes about which physical evidence on the ground controls the survey.
The phrase also appears in older deeds as a general call — "to run with the lines and corners as originally surveyed" — which is a reference to the original survey's authority rather than an independent description.
Why It Matters in Research
This term is almost exclusively a term of art in land law and appears primarily in three contexts in the Law Mind corpus: (1) deed construction disputes, where courts must determine whether a natural monument, an artificial monument, or a recorded course-and-distance call controls when they conflict; (2) boundary litigation, where the original survey's lines and corners are traced against later resurveys, occupation lines, and deed calls; and (3) historical conveyances from the eighteenth and nineteenth centuries, where the phrase is used as a shorthand reference to the controlling original plat or patent survey.
Researchers working in pre-twentieth-century land records should note that "lines and corners" in older Southern and Appalachian conveyances frequently signals a reference back to a state land grant or original entry survey. Mississippi, Alabama, Virginia, and Georgia cases appear repeatedly in the historical sources (Bouvier cites 17 Miss. 459, 21 Ala. 66, 10 Gratt. 445, 16 Ga. 141), reflecting that boundary litigation over original-grant corners was particularly active in those jurisdictions during the nineteenth century.
The phrase also has interpretive weight in deed construction. When a deed conveys land "by the lines and corners" of an adjoining tract, courts must determine whether that call creates a fixed boundary by reference to a third-party survey or simply adopts a common boundary as best ascertainable. This is a recurring source of ambiguity in historical deeds and connects directly to the four corners doctrine in deed interpretation — the question of whether the instrument's language alone controls or whether extrinsic survey evidence is admissible.
Historical Dictionary Support
The four historical sources are in close agreement on the core meaning. Black's and Burrill's are nearly identical: boundary lines and their terminating points where an angle is formed by the next line. Rapalje & Lawrence and Bouvier offer a slight variation — "the angles they make with each other" — that more clearly emphasizes the relationship between lines rather than the terminal point alone. These formulations are functionally equivalent; the difference is one of descriptive emphasis, not legal substance.
None of the historical sources address the interpretive hierarchy problem — what happens when lines and corners as described in a deed conflict with lines and corners as physically established on the ground. That gap is significant for researchers: the phrase is defined in the dictionaries but the operative legal question in most litigation is not what the phrase means but which lines and corners control. For that question, researchers must turn to treatise authority on boundary law (particularly Skelton's Surveying and Boundary Law and later works) and to the case law.
Burrill cites 4 Bibb's R. 133 and 3 Littell's R. 101, 152 — both early Kentucky reports — reflecting that boundary disputes over original survey corners were common in Kentucky's complex land-patent history.
Jurisdictional Note
The term is universal in metes-and-bounds states (primarily east of the principal meridians) but is less operative in public land survey system (PLSS) states, where boundaries are defined by township, range, section, and government corner monuments rather than by individual survey lines and corners. In PLSS states, the analog is the government corner, a term of art within the General Land Office survey system.
