QUICK ANSWER
A legal description identifies a parcel with enough certainty to locate it. National exam prep emphasizes metes and bounds, rectangular (government) survey, and lot and block. Texas uses metes and bounds and lot and block; it never came under the federal rectangular survey because it kept its public lands when it joined the Union. Texas instead traces land to an original survey. For exam purposes, do not substitute a bare address or tax number for the complete description. Under Texas law, sufficiency turns on whether the writing, or another writing it identifies, supplies data that locate the land with reasonable certainty.
EXAM PREP ONLY
This guide explains legal descriptions for the Texas sales agent exam. It is educational content, not legal or surveying advice. A boundary or a legal description in a real transaction must come from a licensed land surveyor and the recorded documents, not from an article. Texas statutes and recording rules can change, so confirm current law before you rely on any point below.
The exam tests legal descriptions in two ways. First, can you name and recognize the three methods? Second, can you do the arithmetic when a rectangular survey question hands you a fraction of a section? Texas adds one more layer, because the state does not use the rectangular system that the National portion still asks about.
What is a legal description?
A legal description is a written identification of a parcel that supplies enough data to locate the land with reasonable certainty. It is different from a street address or tax parcel number, which should not be treated as a substitute for the full description in an exam question or transaction. A deed must identify the land sufficiently, or the transfer can fail.
A legal description answers one question: exactly which piece of land is this? A mailing address like "123 Main Street" and an appraisal-district account number are location or administrative identifiers; standing alone, they do not state the parcel's boundary calls. Texas courts do not apply a magic-words rule, however. A particular address combined with other identifying data in the writing, or in another writing the instrument identifies, can satisfy the reasonable-certainty standard. The exam-safe rule is to use the complete deed, survey, or recorded-plat description rather than assume a bare address is enough.
Why it matters for the exam and for practice is simple. A deed that transfers title must describe the land well enough to identify it.
What Texas law requires of a description
Two Texas provisions sit behind that. Texas Property Code Section 5.021 requires that a conveyance of an estate of inheritance, a freehold, or an estate for more than one year be in writing and be subscribed and delivered by the conveyor or an agent authorized in writing. Separately, Texas Business and Commerce Code Section 26.01(b)(4) puts the contract for the sale of real estate inside the statute of frauds.
How precise the description must be
How good the description has to be is a question of Texas case law rather than statute. The long-settled standard is that the writing must furnish within itself, or by reference to another writing, the means or data by which the land can be identified with reasonable certainty. A description that fails that test can make the instrument unenforceable, so the legal description is not paperwork you can skip.
The three methods of legal description
The three legal description methods are metes and bounds, rectangular (government) survey, and lot and block, also called the recorded plat method. Metes and bounds traces a boundary line by line. The rectangular survey divides land into townships and sections. Lot and block refers to a recorded subdivision plat.
National real-estate courses emphasize three traditional systems, sometimes used in combination. Learn the name, the idea, and where each one is used.
| Method | How it identifies land | Where it is used |
|---|---|---|
| Metes and bounds | Traces the boundary as a series of directions and distances from a starting point back to that same point | The original method in Texas and the eastern states; still used for irregular tracts |
| Rectangular (government) survey | Divides land into a grid of townships and one-mile-square sections using principal meridians and base lines | Most states admitted after 1785; the federal system was never run in Texas |
| Lot and block (recorded plat) | Refers to a lot and block on a subdivision map filed in the county records | Platted subdivisions everywhere, including Texas |
The one Texas twist is in the middle row. The National portion of the exam still tests the rectangular survey system, so you must learn it. Texas was never part of the federal public domain, so its original-survey framework does not use the federal principal-meridian, base-line, township-and-range references.
The nuance most study guides get wrong
"Texas does not use sections and townships" is the version you will hear, and it is too strong. Texas land is described by reference to its original survey, and in the West Texas and Panhandle land the state granted to railroads in the nineteenth century, those original surveys were themselves laid out on a grid. A Permian Basin tract can read "Section 41, Block 57, Township 1, T&P RR Co. Survey, Reeves County, Texas."
The words section, block, and even township genuinely appear in Texas descriptions. What makes them Texas rather than federal is that they number outward from a private railroad grant, not from a principal meridian, and there is no range component at all.
For the exam, hold two things at once:
- The federal Public Land Survey System does not describe Texas land. Texas kept its public domain in 1845, so the federal grid stops at the state line. Learn township, range, and section for the National portion.
- Texas descriptions still name a survey. Every Texas parcel traces back to an original grant, identified by survey name and abstract number, and the county appraisal district and the General Land Office both index land that way.
Metes and bounds: tracing the boundary
A metes and bounds description starts at a fixed point of beginning, then follows a series of calls, each giving a direction and a distance, around the perimeter of the tract until it returns to the point of beginning. Metes are the distances and bounds are the directions and physical markers, called monuments.
Metes and bounds is the oldest method and the everyday method in Texas. Picture walking the edge of a field. You start at a marked corner, then follow each boundary line in turn, writing down the direction you face and how far you walk, until you arrive back where you started.
The parts of a metes-and-bounds description
The parts you need to know:
- Point of beginning (POB). The fixed starting corner. A valid metes and bounds description must close, meaning it ends at the exact point of beginning. If it does not close, it does not describe an enclosed tract.
- Metes. The distances, the length of each boundary line.
- Bounds. The directions and the physical boundaries, including bearings such as "North 45 degrees East."
- Monuments. Physical markers that fix a corner or line. A natural monument is a river, a tree, or a rock. An artificial monument is an iron rod, a fence, or a concrete marker set by a surveyor.
Texas measurement terms
Texas descriptions carry a piece of history here. Early Texas surveys measured distance in varas, a Spanish unit of about 33.33 inches, a little under three feet. Large original grants were measured in leagues and labors. You will still see varas in old field notes and abstract surveys, so recognize the word even though modern surveys use feet.
When calls conflict: the priority of monuments
When calls in a metes and bounds description conflict, the usual priority is natural monuments, artificial monuments or adjoiners, courses, distances, and finally acreage. This hierarchy is a guide for finding the parties' intent, not an automatic rule that overrides better evidence of the grant. The first job is to identify the original called-for monument and the land the instrument intended to convey.
Surveys sometimes contain internal conflicts, and the exam likes to test which call usually wins. The general order is natural monuments, then artificial monuments or adjoiners, then directions, then distances, and finally quantity or acreage. The reason is practical. A river or an identified original iron rod may be stronger evidence than a typed distance. This is also why a stated acreage is usually the weakest call. In a real dispute, though, courts seek the grant's intent and may let a course or distance control when the evidence shows it more clearly identifies the intended boundary.
The rectangular (government) survey system
The rectangular survey system, also called the government or Public Land Survey System, divides land using north to south principal meridians and east to west base lines. A township is six miles square and contains 36 sections. Each section is one mile square and holds 640 acres. Texas does not use this system.
Congress created the rectangular survey in the Land Ordinance of 1785 to divide the public domain into an orderly grid. You need it for the National portion. Texas was left out of the public domain when it joined the Union, so the federal grid was never run here.
Here is the grid, from largest to smallest:
| Unit | Size | Contains |
|---|---|---|
| Township | 6 miles by 6 miles (36 square miles) | 36 sections |
| Section | 1 mile by 1 mile | 640 acres |
| Quarter section | Half mile by half mile | 160 acres |
| Quarter-quarter section | Quarter mile by quarter mile | 40 acres |
Principal meridians and base lines
The reference lines are principal meridians, which run north and south, and base lines, which run east and west. Columns of townships measured east or west of a meridian are called ranges, and rows measured north or south of a base line are called tiers or townships. Because the earth curves, surveyors insert correction lines and guide meridians so the grid stays close to square.
The section-acreage math
The math is the part that shows up on the exam. To find the acreage of a described piece, multiply the fractions together and then multiply by 640.
- The NE 1/4 of a section is 1/4 times 640, which is 160 acres.
- The NW 1/4 of the SE 1/4 is 1/4 times 1/4 times 640, which is 40 acres.
- The S 1/2 of the NW 1/4 is 1/2 times 1/4 times 640, which is 80 acres.
Read these descriptions from the smallest unit backward. "The NW 1/4 of the SE 1/4" means you first find the southeast quarter, then take the northwest quarter of that.
DRILL THE SECTION MATH
Turn "NW 1/4 of the SE 1/4" into 40 acres without hesitating.

Lot and block: the recorded plat method
The lot and block method describes land by referring to a lot and block number on a subdivision plat that has been recorded in the county's official public records. It is the shortest legal description because the plat itself carries the detailed boundaries. Most Texas homes in subdivisions are described this way.
When a developer divides raw land into a subdivision, a surveyor prepares a plat, a map showing every lot, block, street, and easement. Once the plat is approved and recorded, each lot can be described in one short line by naming the lot, the block, the subdivision, and the recording reference.
A typical Texas lot and block description reads like this: "Lot 7, Block 3, Sunset Ridge Addition, an addition to the City of Austin, Travis County, Texas, according to the plat recorded in the official public records." The plat carries the metes and bounds detail, so the deed does not have to repeat it.
When Texas requires a plat
In Texas, platting is regulated, and the governing provision is worth reading closely. Texas Local Government Code Section 212.004(a) requires a plat when an owner divides a tract inside a municipality or its extraterritorial jurisdiction into two or more parts to lay out a subdivision, lots, streets, alleys, squares, or parks intended for public use. It applies however the division is made, including by a metes and bounds description in a deed or a contract for deed, which closes the obvious workaround.
There is a threshold worth memorizing. Section 212.004(a) exempts a division into parts greater than five acres where each part has access and no public improvement is being dedicated. That five-acre line is the kind of concrete number an exam item can be built on.
What a recordable plat must contain
Section 212.004(b) then says what a recordable plat must contain, and one requirement is the strongest evidence that Texas runs its own system: the plat must describe the subdivision by metes and bounds and locate it with respect to a corner of the survey or an original corner of the original survey of which it is a part. Not a meridian. A survey corner. The plat is acknowledged like a deed and filed with the county clerk under Section 212.004(c) and (d).
Because the recorded plat controls, this method ties directly into a clean chain of title, and it is why title work always checks the plat.
Surveys, boundaries, and where they fit in a Texas closing
A survey is the physical measurement of a parcel by a licensed surveyor, and it can produce the metes and bounds a legal description uses. In a Texas transaction, a title company may review a survey with a T-47 affidavit or T-47.1 declaration, or require a new survey, when deciding whether and how to provide survey-related title coverage.
How a survey differs from a legal description
A legal description is words. A survey is the fieldwork behind those words, done by a licensed land surveyor who measures the tract and marks its corners. The two work together, because the survey produces the metes and bounds that the description records.
What the survey does at a Texas closing
In a Texas sale, the survey does real work at closing. Depending on the contract and underwriting facts, the title insurance company may use an acceptable existing survey with the seller's T-47 affidavit or T-47.1 unsworn declaration, or a new survey, to evaluate survey-related exceptions and coverage. Texas title rules allow T-47.1 in lieu of T-47. A survey can reveal an encroachment, where a structure crosses a boundary, or a gap that hints at a boundary dispute or even an adverse possession claim. Those are exactly the clouds a buyer wants found before closing, not after.
Boundaries that follow water add another wrinkle. When a metes and bounds line runs along a river or stream, the boundary can shift as the water moves. That ties legal descriptions to Texas water rights and to the doctrines of accretion and reliction covered under involuntary alienation.
Vertical descriptions: air lots and datums
Some property is described vertically, not just horizontally. A datum is a reference elevation, such as mean sea level, and a benchmark is a fixed point of known elevation. Condominium units and air lots use datums and benchmarks to define space above or below the ground.
Most descriptions are flat, but ownership can be three dimensional. A datum is a fixed reference elevation, often mean sea level, and a benchmark is a permanent marker of known elevation that surveyors measure from. These let a description define a condominium unit or an air lot, a volume of space at a stated height, rather than a patch of ground. You do not need heavy detail here, but recognize the terms and know why a high-rise condominium needs vertical measurement.
Common exam traps to remember
Legal description questions punish a few predictable confusions: treating a street address as a legal description, using township and range on a Texas survey, misreading the acreage math, and forgetting that a metes and bounds description must close at the point of beginning.
- Do not substitute a bare address for the full legal description. A street address or tax number is not one of the traditional survey-description methods. Texas enforceability depends on reasonable certainty from the writing and any identified writing.
- The federal grid stops at the Texas line. Learn township and range for the National portion. Texas's original-survey framework does not use federal township-and-range references, though section, block, and township do appear in West Texas railroad surveys.
- Read the section math backward. "NW 1/4 of the SE 1/4" starts from the southeast quarter. Multiply the fractions, then multiply by 640.
- A metes and bounds description must close. It has to return to the exact point of beginning.
- Monuments usually outrank measurements. Use the standard priority for exam questions, but remember that a real court seeks the grant's intent rather than applying the hierarchy mechanically.

Original practice questions
Use these to check yourself. They are written for practice and are not copied from any real exam.
Question 1. Which method of legal description is not used in Texas?
- A) Metes and bounds
- B) Lot and block
- C) Rectangular (government) survey
- D) The recorded plat method
Answer: C. Texas kept its own public lands when it joined the Union, so the federal rectangular survey was never run here. Texas uses metes and bounds and lot and block, which is the recorded plat method. Note that section, block, and sometimes township appear in West Texas railroad-grant surveys; what is absent is the federal principal-meridian, base-line, township-and-range framework. (Original question.)
Question 2. A description reads "the NW 1/4 of the SE 1/4 of Section 10." How many acres is this?
- A) 160 acres
- B) 80 acres
- C) 40 acres
- D) 640 acres
Answer: C. Multiply the fractions and then by 640: 1/4 times 1/4 times 640 equals 40 acres. Read it from the smallest piece backward, starting at the southeast quarter. (Original question.)
Question 3. With no contrary evidence of the grant's intent, a stated distance conflicts with the identified original iron rod called for as a corner. Which ordinarily controls?
- A) The stated distance
- B) The artificial monument, the iron rod
- C) The stated acreage
- D) Whichever was recorded first
Answer: B. Under the usual priority of calls, the identified artificial monument controls over a conflicting distance. In a real dispute, the hierarchy is evidence of intent rather than an absolute rule, and the surveyor or court must determine whether the marker is the original called-for monument. (Original question.)
Question 4. An agent lists a home and relies only on a bare street address instead of the complete recorded description. What is the safest exam conclusion?
- A) Do not assume the bare address supplies the boundary data needed to identify the parcel with reasonable certainty
- B) Street addresses are illegal in Texas
- C) It is fine, because the address identifies the land
- D) Only the tax account number is required
Answer: A. A bare street address is not one of the traditional description methods and does not itself recite boundary calls. Use the complete deed, survey, or recorded-plat description. Texas courts look to whether the writing, or another writing it identifies, supplies data that locate the land with reasonable certainty; do not turn the exam shortcut into an absolute rule that an address can never contribute to a sufficient description. (Original question.)
Frequently Asked Questions
For quick answers to every common Texas exam question, see the Texas real estate exam FAQ.
What are the three methods of legal description?
The three methods are metes and bounds, rectangular (government) survey, and lot and block, which is also called the recorded plat method. Metes and bounds traces a boundary by direction and distance. The rectangular survey uses a grid of townships and sections. Lot and block refers to a recorded subdivision plat.
Does Texas use the rectangular survey system?
No. Texas retained its own public lands when it joined the United States, so the federal Public Land Survey System was never run here. Texas land is described by metes and bounds or by lot and block, tracing back to an original survey and abstract number. Be careful with the absolute version of this rule: section, block, and even township appear in West Texas and Panhandle railroad-grant surveys. They do not use the federal principal-meridian, base-line, township-and-range framework. You still learn that federal system for the National portion of the exam.
Is a street address enough to describe land in Texas?
Do not assume so. For exam and transaction purposes, use the complete metes-and-bounds or recorded-plat description, because a bare address does not recite the parcel's boundary data. The Texas legal standard is reasonable certainty: the signed writing itself, or another existing writing it identifies, must supply the means or data to identify the land. A particular address plus other identifying language has been sufficient in some Texas cases, so “an address can never help” is too absolute.
What is a metes and bounds survey?
The survey is the fieldwork; the metes and bounds description is the writing that results from it. A licensed land surveyor locates the corners and monuments on the ground and records each boundary call by direction and distance, and that sequence of calls becomes the description recited in the deed. Texas traces land back to an original survey and abstract number rather than to the federal rectangular system, so "survey" in a Texas chain of title usually means that original grant survey, not a township-and-range section. For the exam, keep the two ideas separate: the survey establishes where the boundary runs, and the legal description is how that boundary is written down.
What is the point of beginning?
The point of beginning is the fixed starting corner of a metes and bounds description. The description follows each boundary line by direction and distance and must return to this exact point. If the description does not close back to the point of beginning, it does not describe an enclosed tract.
How many acres are in a section?
A section in the rectangular survey system is one mile by one mile and contains 640 acres. A quarter section is 160 acres, and a quarter of a quarter section is 40 acres. To find the acreage of any described piece, multiply the fractions together and then multiply by 640.
What is a vara in a Texas land description?
A vara is an old Spanish unit of length equal to about 33.33 inches, a little under three feet. Early Texas surveys measured distances in varas and larger grants in leagues and labors. You will still see varas in historic field notes and abstract surveys, though modern surveys use feet.

Sources and Methodology
This article was reviewed against Texas primary sources and standard national survey principles on August 12, 2026. The Texas General Land Office records support the state's original-survey framework and its railroad-grant terminology. Texas Property Code Section 5.021, Business and Commerce Code Section 26.01, and Texas Supreme Court decisions supply the writing and reasonable-certainty rules. Texas boundary cases treat the priority of calls as a tool for identifying the grant's intent, not a mechanical substitute for it. Texas subdivision platting is governed by Local Government Code Chapters 212 and 232. The Texas title-insurance manual and current TREC contract materials recognize both the T-47 affidavit and T-47.1 unsworn declaration. Statutes, forms, underwriting requirements, and case law can change, so verify the current primary sources before relying on any point in practice.
