Legal Descriptions in Texas: The Real Estate Exam Guide

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?

Snippet answer: A legal description is a written identification of a parcel of land that is precise enough for a surveyor to locate its exact boundaries on the ground. It is different from a street address or a tax parcel number. A valid deed must contain a legal description sufficient to identify the land, 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" points to a mailbox, but it does not fix the corners of the lot, so it is not a legal description. The same is true of an appraisal district account number, which is an administrative label, not a boundary.

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. Texas requires conveyances of real property to be in writing under the statute of frauds, and courts expect a description that a surveyor could follow. A vague or missing description can make a deed unenforceable, so the legal description is not paperwork you can skip.

The three methods of legal description

Snippet answer: 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.

Every legal description in the United States uses one of three systems, or sometimes a combination. Learn the name, the idea, and where each one is used.

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. Just remember that you will not find a township and range description on a Texas survey, because Texas runs its own system instead.

Metes and bounds: tracing the boundary

Snippet answer: 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 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 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

Snippet answer: When the parts of a metes and bounds description disagree, courts follow an order of priority. Natural monuments control first, then artificial monuments, then courses (directions), then distances, and acreage is the least reliable. A physical marker on the ground generally beats a number on paper.

Surveys sometimes contain internal conflicts, and the exam likes to test which call wins. The general order is natural monuments, then artificial monuments, then directions, then distances, and finally quantity or acreage. The reason is practical. A river or an iron rod is hard to move, while a typed distance is easy to mistype. This is also why a stated acreage is the weakest call. A description that says "10 acres more or less" gives way to the boundaries that the monuments and courses actually enclose.

The rectangular (government) survey system

Snippet answer: 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, even though no Texas parcel is described this way.

Here is the grid, from largest to smallest:

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 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.

Lot and block: the recorded plat method

Snippet answer: 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.

In Texas, platting is regulated. Under the Texas Local Government Code, a subdivision plat generally must be approved by the city or the county before the county clerk will record it. It must then be filed in the county's real property records under the Texas Property Code. 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

Snippet answer: A survey is the physical measurement of a parcel by a licensed surveyor, and it produces the metes and bounds that a legal description uses. In Texas transactions, the title company relies on a survey and a T-47 affidavit to provide area and boundary coverage and to catch encroachments and boundary problems.

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.

In a Texas sale, the survey does real work at closing. The title insurance company uses an existing survey and a signed T-47 affidavit, or a new survey, to decide whether it will delete the standard survey exception and provide area and boundary coverage. 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

Snippet answer: 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

Snippet answer: 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.

• A street address is not a legal description. Neither is a tax account number. The exam loves this distinction.
• Texas does not use the rectangular survey. Learn township and range for the National portion, but know no Texas parcel is described that way.
• 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 beat measurements. When calls conflict, natural monuments win first and stated acreage is the weakest call.

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 and Spanish and Mexican land grants when it joined the Union, so it never adopted the rectangular survey system. Texas uses metes and bounds and lot and block, which is the recorded plat method. (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. In a metes and bounds description, the parts disagree. A stated distance conflicts with an iron rod set at a corner. Which controls?

• A) The stated distance
• B) The artificial monument, the iron rod
• C) The stated acreage
• D) Whichever was recorded first

Answer: B. Monuments outrank measurements. A physical marker on the ground beats a typed distance, and stated acreage is the weakest call of all. (Original question.)

Question 4. An agent lists a home and writes only the street address on the contract as the description of the property. Why is that a problem?

• A) A street address is not a legal description and does not fix the boundaries
• 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 street address points to a location but does not identify the exact boundaries of the parcel, so it is not a legal description. Texas contracts and deeds rely on a legal description or a recorded plat reference. (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 never adopted the rectangular or Public Land Survey System, because it retained its own public lands and its Spanish and Mexican land grants when it joined the United States. Texas land is described by metes and bounds or by lot and block. You still learn the rectangular system for the National portion of the exam.

Is a street address a legal description?

No. A street address identifies a location for mail and navigation, but it does not fix the exact boundaries of the parcel. A legal description must be precise enough for a surveyor to locate the corners, which is why deeds use metes and bounds or a recorded plat reference instead.

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 July 21, 2026. The point that Texas never adopted the rectangular or Public Land Survey System, and instead relies on metes and bounds and its original Spanish and Mexican land grants, reflects the history of the Texas public domain and the records held by the Texas General Land Office, which was established in 1837. The vara as a unit of about 33.33 inches, along with leagues and labors, comes from the Spanish and Mexican survey heritage still visible in Texas field notes and abstract surveys. The rectangular survey figures, a township of 36 sections and a section of 640 acres, are standard measures from the federal system created by the Land Ordinance of 1785. The requirement that Texas conveyances be in writing and identify the land reflects the Texas statute of frauds and the description sufficiency courts require in a deed. Texas subdivision platting and recording are governed by the Texas Local Government Code and the Texas Property Code, which require plat approval and recording in the county's official public records. The priority of calls, with natural monuments controlling over artificial monuments, courses, distances, and quantity, reflects long-settled Texas boundary case law. Statutes, rules, and case law can change, so verify the current Texas Local Government Code, Texas Property Code, and General Land Office guidance before relying on any point in practice.
