A legal description of property is the precise written identification of a parcel’s boundaries that appears on a deed, mortgage, or title policy, and it takes one of three forms in the United States: metes and bounds, lot and block, or the government rectangular survey. A street address tells the postal service where to deliver mail, but it does not define the exact perimeter of the land, and municipalities can renumber or rename streets at any time. The legal description does the work the address cannot. It locks down the parcel so precisely that no other piece of ground on earth matches, which is why the statute of frauds in every state requires real property transfers to be in writing with a description specific enough to identify the land.
Every deed, mortgage, and title insurance policy depends on this language. If you pull your closing documents and look past the address block, you will find a paragraph (sometimes a page) that looks like one of the three systems below. Which one depends mostly on where the property sits.
Metes and Bounds
Metes and bounds is the oldest method, dating to colonial land grants. It traces the outer boundary of a parcel from a fixed starting point, called the Point of Beginning, through a series of directions and distances until the line closes back where it started. “Metes” refers to the measured distances; “bounds” refers to the directions and the physical markers along the way.
Each segment of the boundary is called a call, and a call combines a compass bearing with a distance. You will see language like “North 45 degrees East, 200 feet,” which tells the surveyor to walk that heading for that distance before turning to the next call. Follow every call in sequence and you should end up back at the Point of Beginning. If the final line does not close, the survey has a mathematical error and cannot be used for legal purposes.
Monuments anchor these descriptions to the ground. Natural monuments are landscape features: rivers, ridgelines, large boulders. Artificial monuments are objects placed by people, such as iron pins, concrete posts, or brass survey caps. These markers give a surveyor something to find on-site instead of relying on measurements alone. Monuments also erode, get buried, or get removed, and when that happens the description loses its physical reference and needs updating.
Metes and bounds is the default in the original thirteen colonies, Texas, and other states that were never part of the federal rectangular survey. It also shows up everywhere else for irregularly shaped parcels that do not fit a grid.
When a metes and bounds description contains internal contradictions (a bearing that points one way while a monument sits off that line, or stated acreage that does not match the enclosed area), courts and surveyors resolve the conflict using a fixed ranking: natural monuments outrank artificial monuments, which outrank distances, which outrank bearings, which outrank the stated acreage.1Bureau of Land Management.

Lot and Block
Lot and block is what most suburban and urban homeowners encounter. Instead of tracing compass bearings around each parcel, a licensed surveyor draws a detailed map of an entire subdivision, called a plat, that divides a large tract into numbered lots grouped within numbered blocks. The plat also shows streets, utility easements, setback lines, and common areas. Local planning authorities review and approve the plat before it is recorded in the county’s public records.
Once the plat is on file, the legal description is short and clean: “Lot 7, Block 12, Oak Ridge Estates, as recorded in Plat Book 34, Page 19, of the records of [County], [State].” That single line points anyone to the master map, where the dimensions and boundaries of Lot 7 are already drawn. No compass bearings, no monument references, no multi-page narratives.
The simplicity is the point. Every parcel in the subdivision is tied to one authoritative map, so title searches are faster, deeds are shorter, and there is less room for ambiguity. The tradeoff is that the system only works where someone has already gone to the expense of creating and recording the plat. Rural and unsubdivided land still needs one of the other two methods.
Government Rectangular Survey
The Government Rectangular Survey System, also called the Public Land Survey System, was created by the Land Ordinance of 1785 to impose order on the territories the federal government was preparing to sell. Surveyors laid out a grid of intersecting lines across most of the country west of the original colonies: principal meridians running north-south and base lines running east-west. Every measurement in the system traces back to one of these reference lines.
The grid divides land into townships, each a six-mile square containing 36 square miles. A township’s location is described by its distance from the nearest principal meridian (its “range”) and its distance from the base line (its “township” number). Within each township, the 36 square miles are divided into sections numbered 1 through 36. Numbering starts at the northeast corner with section 1, runs west to section 6, drops to section 7 on the west side, snakes east to section 12, and continues this pattern until section 36 sits in the southeast corner.
Each section is one square mile, or roughly 640 acres, and sections can be subdivided into halves and quarters. A description like “the Northwest Quarter of the Southeast Quarter of Section 14, Township 3 North, Range 2 East” pinpoints a 40-acre parcel with no monuments and no compass calls, just grid coordinates.
The system covers roughly 30 states, mostly west of the Appalachian Mountains. It does not apply in the original thirteen colonies, Texas, Hawaii, or parts of Ohio where earlier colonial surveys had already been completed. If your property sits in a rectangular survey state, your deed almost certainly references a section, township, and range.
Where to Find Your Property’s Legal Description
The single best source is your deed. Every deed recorded in the county land records contains the full legal description of the parcel being transferred. If you do not have a copy, the county recorder’s office (also called the register of deeds or clerk of court) keeps the original. Many counties now offer online portals where you can pull up recorded documents by owner name or property address.
Your title insurance policy is another reliable source. The policy schedules include the legal description exactly as it appeared in the deed at closing. Mortgage documents also contain the description, because the lender needs to identify the collateral. Any of these three will give you the language you need.
The county assessor’s office assigns each parcel a tax identification number, sometimes called an Assessor’s Parcel Number or Parcel ID. That number is useful for looking up tax records and locating the parcel on the assessor’s map, but it is not the legal description and should never be used in place of one on a deed or contract. The tax ID is a filing shortcut; the legal description is the actual identity of the land.
If the description in your deed does not match a current survey, or if you are buying unimproved land that has never been formally described, you will need a licensed surveyor to create or verify the description. A standard residential boundary survey runs roughly $300 to $1,200, depending on parcel size, terrain, and local market.
Fixing an Error in a Legal Description
Mistakes in legal descriptions are more common than most people expect. A transposed number in a bearing, a missing lot digit, or a misidentified section can mean the deed technically describes the wrong piece of land. The fix depends on how serious the error is.
Minor clerical errors, like a misspelled subdivision name or a missing word in a call, can often be corrected with a scrivener’s affidavit. This is a sworn statement, typically prepared by the attorney or title professional who handled the original document, identifying the error and stating the correct information. The affidavit is recorded in the same county office as the original deed and becomes part of the public record. Most states authorize this process, though the specific requirements vary by jurisdiction.
More significant errors usually require a corrective deed. The original grantor signs a new deed with the correct legal description, and it is recorded alongside the original. The corrective deed does not create a new transfer of ownership; it fixes the paperwork. The practical challenge is that you need the original grantor’s cooperation, which gets harder as time passes.
When the error is severe enough that it is unclear what property was actually conveyed, or when the original grantor cannot be found, a quiet title action may be necessary. This is a lawsuit asking a court to declare who owns the property and to establish the correct legal description as a matter of public record. Quiet title actions are expensive and slow, but they are sometimes the only way to clear a defect that cannot be resolved with a simpler document. The description in the petition itself must be accurate; courts have dismissed these actions when the petition described the wrong parcel entirely.
