Quick reference

U.S. Public Land Survey System

  • A principal meridian runs north-south and a base line runs east-west; their intersection is the initial point for the survey system.

  • A standard township contains 36 sections, each nominally 1 mile square and 640 acres; the township totals 23,040 acres.

  • Section numbering begins at the northeast corner with Section 1 and proceeds west to Section 6, then east to Section 7, alternating boustrophedon through Section 36.

  • Aliquot parts divide a section by halves and quarters: 1/2 = 320 acres, 1/4 = 160 acres, 1/4 1/4 = 40 acres; descriptions list the smallest part first.

  • Meander corners are set where survey lines intersect a bank, shore, or water body; meander lines are run to compute water area and are not legal boundaries.

  • Lost corner restoration uses proportionate measurement between the nearest existing original corners; single proportionate measurement applies to a corner on one line, double proportionate to an interior corner.

  • Closing corners are established on standard parallels and are not moved to conform to later surveys; fractional lots commonly occur along north and west township lines.

  • Original government corners are the best evidence of the PLSS; retracement surveys must not create new original corners.

Boundary Evidence and Rules of Construction

  • The general hierarchy for conflicting calls is natural monuments, artificial monuments, adjoiners, courses and distances, and area.

  • A call for a monument generally controls a conflicting distance, course, or area call.

  • Original survey evidence prevails over subsequent survey evidence when both exist and conflict.

  • Courses and distances control area; area is the weakest call and yields to monuments, adjoiners, courses, and distances.

  • A latent ambiguity is not apparent on the face of the document and may be explained by extrinsic evidence.

  • An original monument found in place is presumed correct; an obliterated corner may be restored from record and physical evidence.

  • A subsequent survey is a retracement and cannot alter the location of an original boundary.

  • A call for an adjoiner may control over a distance call when the adjoiner's boundary is certain.

Quick reference

Water Boundaries

  • Riparian rights attach to land bordering a watercourse; littoral rights attach to land bordering a lake, sea, or ocean.

  • Accretion is gradual and imperceptible addition of land by water action; title to the added land belongs to the upland owner.

  • Reliction is the gradual withdrawal of water exposing new land; the upland owner gains title to the exposed land.

  • Erosion is gradual loss of land by water action; the boundary follows the receding water line.

  • Avulsion is a sudden or perceptible change in a watercourse or shoreline; the boundary remains at its pre-avulsion location.

  • For navigable waters, the upland boundary is generally the ordinary high water mark, and the state owns the submerged bed.

  • For non-navigable streams, the boundary is typically the thread or middle of the stream unless the deed states otherwise.

  • Meander lines are not legal boundaries; they are used to compute the area of water and adjoining fractional lots.

Legal Descriptions, Deeds, and Conveyances

  • A valid deed requires a grantor, grantee, words of grant, legal description, signature, delivery, and acceptance.

  • A description is sufficient if it identifies the land with reasonable certainty or can be made certain by extrinsic evidence.

  • Specific descriptions control general descriptions; monuments control courses, distances, and area.

  • An exception excludes land from the grant; a reservation retains a right or interest in the grantor.

  • A latent ambiguity is not apparent on the face of the deed and may be resolved by extrinsic evidence.

  • Reformation corrects a written instrument to reflect the parties' original agreement, usually for mutual mistake.

  • A metes-and-bounds description begins at a point of commencement and runs to a point of beginning; the point of beginning should be monumented.

  • Recording a deed does not cure a void legal description.

Quick reference

Easements, Rights-of-Way, Encroachments, and Encumbrances

  • An easement appurtenant benefits a dominant parcel and burdens a servient parcel; an easement in gross benefits a person or entity.

  • Express easements are created by writing; implied easements arise from prior use or necessity; prescriptive easements arise from adverse use.

  • An easement by necessity requires unity of title and strict necessity for access.

  • The scope of an easement is fixed by the grant and the reasonable needs of the dominant estate at the time of creation.

  • An encroachment is a physical intrusion onto another's land; remedies include injunction, damages, or removal.

  • An encumbrance includes easements, liens, covenants, conditions, restrictions, and encroachments.

  • Easements terminate by merger, release, abandonment, prescription, or estoppel.

  • A right-of-way is an easement for passage; its width is set by the document or by the established use.

Quick reference

Adverse Possession, Prescription, Boundary Agreements, and Quiet Title

  • Adverse possession requires actual, open and notorious, exclusive, continuous, and hostile possession for the statutory period.

  • Color of title allows constructive possession of the entire described parcel, not just the portion actually occupied.

  • Tacking joins successive adverse possessors' periods when privity exists between them.

  • Prescription acquires an easement, not fee title, through adverse use for the statutory period.

  • A boundary line agreement requires an uncertain or disputed boundary, an agreement, and performance or acquiescence.

  • Quiet title is a court action to adjudicate competing claims and confirm title.

  • Possession must be hostile; permission or co-tenancy generally defeats adversity.

  • Statutory periods for adverse possession and prescription vary by state and by claim type.

Quick reference

Record Mapping and Subdivision Law

  • A record of survey maps evidence of boundary location; a subdivision plat creates lots and may include dedications.

  • A lot line adjustment relocates a boundary between existing parcels without creating additional lots.

  • Subdivision approval typically requires a tentative map, final map, and local government approval.

  • Monuments set during a survey must be shown on the record map with ties to existing control.

  • A corner record perpetuates evidence of a corner that is not shown on a recorded map.

  • Plats and surveys are filed with the county recorder or surveyor as required by state statute.

  • An ALTA/NSPS survey follows national standards for title and lending purposes.

  • Record maps must show bearings, distances, curves, and areas consistent with the survey.

Professional Standards, Ethics, and the Surveyor's Role

  • The surveyor locates and reports boundary evidence; courts decide legal title and boundary disputes.

  • A surveyor may interpret deeds and maps as part of the survey but may not give legal advice.

  • Professional ethics require disclosure of conflicts of interest and avoidance of contingent fees in boundary opinions.

  • Surveyors must maintain objectivity and not favor the client's desired boundary over the evidence.

  • Errors or omissions affecting the public or client should be disclosed and corrected.

  • Expert testimony must be based on accepted surveying principles and complete evidence.

  • Records and field notes should be retained according to state statute and professional standards.

  • A surveyor should not certify a boundary location without sufficient evidence.
