Property Ownership exam concept
Legal description methods
Start with what anchors the land. A journey through boundary calls suggests metes and bounds. Section, township, range and meridian identify the public survey grid. A named lot tied to a recorded subdivision plat points to lot and block. Then read the rest: two descriptions can use the same method and acreage while identifying different land.

The short answer
Metes and bounds describes boundaries through courses, distances, monuments and related calls. Rectangular survey locates land by principal meridian, township, range, section and its subdivisions or government lots. Lot and block identifies land through a recorded subdivision plat. Check the entire description, including exceptions. An address or PIN is a useful record cross-check, not a replacement for sufficient parcel identification.
Reviewed October 25, 2026. PSI National I.B.1-3 lists the three methods; Illinois III.E covers legal descriptions and the Plat Act. The full Property Ownership domain has 10 of 100 scored national questions. The full Additional Illinois Laws and Regulations domain has 10 of 40 state questions. These are not page-specific quotas. Nominal acreage examples are teaching models, not surveyed boundary determinations. This guide does not prepare, repair or approve a conveyance description.
Identify the anchor, then locate the parcel
- Recognize the method without relying on one word. Bearings, distances, monuments and adjoining lines are metes-and-bounds clues. Directional quarters within a section belong to the rectangular survey system. A numbered lot can be a subdivision lot or a government lot, so find the record it refers to.
- For a closed perimeter, separate the approach from the boundary. A point of commencement can lead from a known reference to the point of beginning. Follow the actual perimeter from there. Not every metes-and-bounds-based description is a closed perimeter; a specified-width strip can instead follow a center line to a termination point.
- For nested section fractions, locate the larger tract first. In the E 1/2 of the NW 1/4, find the northwest quarter of the section, then its east half. The wording names the smallest part first. To locate it, start at the section and apply the divisions from right to left.
- For lot and block, find the named recorded plat. Match the lot, any block, subdivision, amendments and recording reference. A lot number alone is not unique. Do not assume that a condominium mailing number is the legal unit identifier shown on its plat and declaration.
- Keep all additions, exceptions and interests. A description may combine the grid, a plat reference and perimeter calls. Less-and-except language removes described land; an easement burden or appurtenant right is a different issue. Compare the complete exhibits, not only the first line.
- Cross-check and refer discrepancies. Compare the contract, proposed deed, title record, survey or plat, parcel count, address and PINs. A broker can accurately transmit existing text but should not choose a new boundary, delete an exception or change a bearing to make a description close.
| Method | Fingerprint | Anchor | Exam move |
|---|---|---|---|
| Metes and bounds | Courses, distances and boundary references | Locatable beginning and control | Trace the described boundary or strip |
| Rectangular survey | Section, township, range and divisions | Principal meridian and base line | Locate the larger division, then the smaller part within it |
| Lot and block | Lot on a named recorded subdivision | The actual recorded plat | Match the lot and all applicable references |
| Government lot | Numbered lot within the public survey | Official survey plat and records | Do not assume a fixed acreage |
| Street address | Number and street | Local addressing system | Use only as cross-check |
| PIN | Tax index number | Assessor or recorder index | Confirm parcel count |
The distinctions that matter
| Distinction | How it works | What to notice |
|---|---|---|
| Metes and bounds vs. lot and block | Metes and bounds uses boundary calls. Lot and block identifies land by reference to the recorded subdivision. A description can combine both methods. | Boundary calls versus plat reference. |
| Rectangular survey vs. lot and block | Rectangular survey uses section, township, range, and meridian. Lot and block uses a developer's or surveyor's recorded subdivision grid. | Government grid versus recorded subdivision. |
| Metes vs. bounds | Metes are measured courses, directions, and distances. Bounds are monuments and adjoining physical or legal features. | Measurements versus boundary features. |
| Point of commencement vs. point of beginning | A commencement point is an approach reference. The point of beginning starts the described boundary; a closed perimeter returns there. A strip center line can instead have a point of termination. | Approach point versus boundary start. |
| Township tier vs. range | A township tier is counted north or south of a base line. A range is counted east or west of a principal meridian. | North-south position versus east-west position. |
| Survey township vs. civil township | A survey township is the nominal six-mile PLSS grid. A civil township is a local governmental unit and does not define the federal survey square merely because the word township appears. | Land grid versus local government. |
| Section vs. quarter section | A standard section is nominally 640 acres. A quarter section is one-fourth of it, nominally 160 acres. | Whole grid square versus one quarter. |
| Legal description vs. address | A legal description identifies land boundaries for title purposes. An address identifies a location for navigation, occupancy, or service. | Parcel identity versus street location. |
| Legal description vs. PIN | A legal description identifies the land or interest. A PIN indexes tax records and helps cross-check it. A mismatch needs resolution; do not use the PIN alone to rewrite the deed boundary. | Boundary language versus record index. |
| Survey exception vs. description exception | A survey exception concerns a physical or title item shown or discoverable by survey. A phrase such as 'less and except' removes described land from the parcel itself. | Title coverage issue versus land excluded. |
| Government lot vs. subdivision lot | A government lot is identified within the public land survey records. A subdivision lot comes from its recorded subdivision plat. Neither the word lot nor its number gives a universal acreage. | Read which survey or plat creates the lot. |
Work through the facts
Metes-and-bounds fingerprint
A deed says to commence at a section corner, travel 420 feet to the point of beginning, then follow four bearings and distances back to the point of beginning.
- The section corner is a reference point used to approach the parcel.
- The expressly named point of beginning starts the actual perimeter.
- Bearings, distances, and closure identify the method.
Answer: This is a metes-and-bounds description. The point of commencement and point of beginning perform different jobs.
Nested rectangular fraction
A description conveys the E 1/2 of the NW 1/4 of Section 14 in a stated township, range, and principal meridian.
- Start with the 640-acre nominal section.
- The northwest quarter is nominally 160 acres.
- The east half of that quarter is nominally 80 acres.
Answer: This is a rectangular survey description of a nominal 80-acre tract, subject to actual survey conditions.
Quarter of a quarter
The deed describes the SW 1/4 of the NE 1/4 of a standard section.
- Locate the northeast quarter first because it appears closest to the section reference.
- That tract is nominally 160 acres.
- Take its southwest quarter to reach a nominal 40 acres.
Answer: This is the southwest quarter within the northeast quarter, nominally 40 acres. Locate NE first, then SW within it; do not swap the two directions.
Recorded subdivision lot
A fictional teaching description identifies Lot 18 in Oak Ridge Subdivision according to a stated plat document in Lake County, Illinois. It includes no block number.
- The lot and named subdivision are explicit.
- The document reference identifies the incorporated plat.
- The referenced plat supplies the lot boundaries and other recorded details; inspect the actual plat and applicable title records.
Answer: This is lot and block, even though the sample wording does not happen to include a block number.
Two parcels under one address
A house and detached garage use one street address, but the title commitment lists two legal descriptions and two PINs.
- The address identifies the occupied location but not the number of title parcels.
- Both descriptions must be compared with the contract, deed, survey, and intended sale.
- Omitting the garage parcel could leave the seller with land the parties expected to convey.
Answer: Use the legal descriptions as controlling parcel identifiers and the address and PINs as cross-checks.
Description does not close
A typed exhibit follows several boundary calls but ends 35 feet from the stated point of beginning when plotted.
- The mismatch may reflect a transcription error, omitted call, bad bearing, wrong distance, or a more complex controlling-boundary issue.
- A broker should not alter a number to force closure.
- The source documents, title record, and professional survey analysis need review before execution or recording.
Answer: Pause the affected document process and obtain qualified survey, title and legal review. Do not invent a corrected boundary or decide deed validity from the plotting discrepancy alone.
Same acreage does not mean the same land
Compare the NE 1/4 of the SW 1/4 with the SW 1/4 of the NE 1/4 in the same standard section.
- Each nominal calculation is 640 x 1/4 x 1/4 = 40 acres.
- The first is inside the southwest quarter. The second is inside the northeast quarter.
Answer: Both are nominally 40 acres, but they are different tracts. Multiplication checks area, not location.
A government lot is not a standard quarter
A fictional official-survey-record example identifies Government Lot 7 as 23.48 acres within a stated section, township, range and meridian.
- The survey-lot number does not mean seven acres or a fixed fraction of 640 acres.
- The supplied record gives the acreage for this example.
Answer: Use 23.48 acres. Do not replace a numbered government lot with a nominal quarter-quarter section.
One description combines methods
An existing description begins with a lot on a named recorded subdivision plat, then excludes a separately described ten-foot strip along one side.
- The plat locates the base lot.
- The exception limits the land included in that base description.
- Deleting the exception could change the parcel even though the lot number stays the same.
Answer: Read the full lot-and-exception description. Do not call the strip an easement merely because it is narrow.
A condominium unit is tied to its recorded instruments
A building calls an apartment Door 702, but the condominium plat and declaration identify the intended legal unit as Unit 7B.
- The mailing label and legal unit identifier have different jobs.
- Section 7 of the Illinois Condominium Property Act addresses the identifying number or symbol shown on the plat and set forth in the declaration.
Answer: Verify Unit 7B against the instruments and intended transaction. Do not substitute Door 702 as though the labels necessarily match.
A PIN mismatch does not automatically invalidate the deed
A residential conveyance in a county with at least 3,000,000 inhabitants lacks matching PINs and the alternative documentation described in Section 35d.
- That section has specific county, property and grantor-to-grantee requirements.
- It expressly says failure to provide the PINs does not invalidate the deed.
- The compliance and possible liability issues still need resolution.
Answer: Do not announce that the deed is void or that the PIN is the complete boundary description. Refer the mismatch for proper correction and advice.
A strip center line need not return to its beginning
A description defines a stated-width utility strip by a center line ending at a specified boundary, with the necessary side and end treatment.
- BLM describes this as a modified metes-and-bounds form.
- Its described center line can end at a point of termination rather than travel around a closed perimeter.
Answer: Identify a strip description. The missing return call alone does not establish a defective closed parcel; evaluate the actual form and complete terms.
Mistakes to avoid
- Treating the street address as controlling Use the address as a cross-check. Do not substitute it for a sufficient parcel description or decide a disputed instrument's validity from the address alone.
- Treating a PIN as a legal description A PIN indexes tax and land records. It helps verify parcel count but does not replace sufficient boundary language.
- Confusing commencement with beginning Commencement can lead to the boundary start. A closed parcel perimeter returns to its point of beginning; a strip center line can instead terminate at its defined end.
- Calling every directional description metes and bounds Rectangular descriptions also use directional quarters. Look for bearings and perimeter calls versus township, range, section, and aliquot parts.
- Locating nested aliquot parts in the wrong order Start with the section and locate divisions from right to left. Multiplying the same fractions gives the same nominal area but does not prove the same location.
- Assuming every section contains exactly 640 acres The figure is nominal. Corrections, government lots, water, and actual survey records can produce different acreage.
- Assuming lot and block needs the word block Some plats number lots without blocks. The decisive clue is reference to a lot on a named recorded plat.
- Ignoring the referenced plat The plat can show easements, dedications, dimensions, notes, and restrictions that the short description omits.
- Dropping 'less and except' language An exception removes land from the grant. Omitting it can materially change the described parcel.
- Assuming acreage controls a boundary Acreage can be an estimate or subordinate call. Boundary analysis requires the complete description, survey evidence, and governing law.
- Correcting a suspicious call by guess Changing a bearing or distance can change title. Refer an ambiguity or closure failure to qualified professionals.
- Writing a new parcel from a tape measurement Illinois treats preparation of boundary descriptions for title or property rights as professional land surveying work.
Check your understanding
These are original teaching questions, not recalled or predicted PSI questions. Answer first, then explain why the other choices fail.
1. Which words most clearly identify a metes-and-bounds description?
- Point of beginning, bearing, and distance
- Lot 7 and recorded subdivision
- Street number and ZIP code
- Township 3 North and Range 8 East
Show answer and explanation
Answer: A. Point of beginning, bearing, and distance
These are characteristic boundary calls. A closed parcel description traces its perimeter; not every strip description needs the same closed-loop form.
2. In the rectangular survey system, ranges are counted in which direction?
- East or west of a principal meridian
- Clockwise from a point of beginning
- North or south of a base line
- Only along county lines
Show answer and explanation
Answer: A. East or west of a principal meridian
Ranges locate the survey township east or west of the principal meridian. Township tiers are counted north or south of the base line.
3. What is the nominal acreage of the NE 1/4 of the SW 1/4 of a standard section?
- 160 acres
- 80 acres
- 40 acres
- 20 acres
Show answer and explanation
Answer: C. 40 acres
The southwest quarter is 160 nominal acres. Its northeast quarter is 40 nominal acres.
4. A description names Lot 9 in a subdivision according to a recorded plat. Which method is being used?
- Metes and bounds
- Street-address description
- Lot and block
- Government rectangular survey only
Show answer and explanation
Answer: C. Lot and block
The lot gains its boundary meaning from the named recorded subdivision plat. A separate block number is not required on every plat.
5. A broker notices that the proposed deed description differs from the last recorded deed and does not close when plotted. What is the best response?
- Use only the street address
- Stop and obtain qualified title, survey, and legal review
- Change the final distance so it reaches the beginning
- Record both versions and let the buyer choose later
Show answer and explanation
Answer: B. Stop and obtain qualified title, survey, and legal review
A description defect can change the land conveyed. A broker should flag and route the issue, not create a boundary correction.
6. How do you locate the E 1/2 of the NW 1/4 of a standard section?
- Find the northwest quarter, then its east half
- Begin at a street-address point
- Find the east half, then its northwest quarter
- Use any 80-acre parcel in the county
Show answer and explanation
Answer: A. Find the northwest quarter, then its east half
The larger named division nearest the section is NW 1/4. Its E 1/2 is nominally 80 acres; the reversed location is different.
7. Two descriptions in the same section are NE 1/4 of SW 1/4 and SW 1/4 of NE 1/4. Which is correct?
- Their acreage must differ
- Their nominal areas match but their locations differ
- They are necessarily the same tract
- Each is a lot-and-block description
Show answer and explanation
Answer: B. Their nominal areas match but their locations differ
Each has nominal area 640 x 1/4 x 1/4 = 40 acres. The containing quarter and the quarter selected within it are different.
8. An official record gives Government Lot 7 as 23.48 acres. What should replace that area solely because the lot is numbered 7?
- Forty acres in every case
- Seven acres
- One seventh of a section
- Nothing; the number does not impose a fixed acreage
Show answer and explanation
Answer: D. Nothing; the number does not impose a fixed acreage
Government-lot numbers identify surveyed lots, not a fixed area or ordinary subdivision-block sequence. Use the supplied record for this example.
9. A complete description identifies a subdivision lot, less and except a separately defined strip. What is the principal risk in dropping the exception?
- It necessarily creates a new principal meridian
- It automatically converts the deed to a mortgage
- It can change the land described in the grant
- It only changes the mailing address
Show answer and explanation
Answer: C. It can change the land described in the grant
The exception removes described land from the base parcel. Its effect differs from merely describing an easement burden.
10. An actual irregular section contains 636 acres. With no further survey information, can you establish the acreage of its N 1/2 simply by dividing 636 by 2?
- Yes, if the street address is known
- Yes, every legal half must have exactly half the area
- Yes, because every section still has 640 acres
- No; actual subdivision boundaries and tract records are needed
Show answer and explanation
Answer: D. No; actual subdivision boundaries and tract records are needed
Nominal equal-area teaching arithmetic does not settle actual aliquot boundaries or prove actual area from the whole-section total.
11. Under Illinois Conveyances Act Section 35d, failure to provide the specified PINs for a covered residential conveyance does what to deed validity by itself?
- It converts the PIN into a full boundary description
- It always voids the deed
- It does not invalidate the deed, although the compliance issues remain
- It resolves every survey and title defect
Show answer and explanation
Answer: C. It does not invalidate the deed, although the compliance issues remain
The section has a specific county/property scope and alternatives, and expressly preserves validity despite the failure. It does not excuse noncompliance or settle all title questions.
12. A stated-width utility strip is fully described along a center line to a defined termination point. What is the best conclusion about the missing return call?
- It alone does not establish a defective closed perimeter; evaluate the strip form
- It always proves the land was abandoned
- It means the broker may invent a closing bearing
- It means the width can be ignored
Show answer and explanation
Answer: A. It alone does not establish a defective closed perimeter; evaluate the strip form
BLM explains strip descriptions as modified metes-and-bounds forms. A center line need not describe a loop around the perimeter; full identification and proper terms still matter.
Common questions
What are the three main legal description methods?
The three methods tested on the real estate exam are metes and bounds, government rectangular survey, and lot and block. Metes and bounds traces a parcel from a point of beginning. Rectangular survey identifies land by section, township, range, and principal meridian. Lot and block incorporates a recorded subdivision plat.
What is a metes-and-bounds description?
It uses boundary calls such as courses, distances, monuments, adjoining lines and curves to locate the land or interest. A closed parcel perimeter returns to its point of beginning. A strip described by a center line is a different form and can terminate without that return call. Read the entire description and its purpose.
What is the point of beginning?
It is the starting point of the actual described boundary. A point of commencement can be a separate reference used to reach it. A closed parcel perimeter returns to its beginning; do not apply that closed-loop shortcut to every center-line strip description.
How does the government rectangular survey system work?
A principal meridian and base line establish references. Township tiers are counted north or south of the base line, and ranges are counted east or west of the meridian. Their intersection identifies a survey township, nominally six miles square and divided into 36 sections.
How many acres are in a section and a quarter section?
A standard section is nominally 640 acres. A half section is 320 acres, a quarter section is 160 acres, and a quarter-quarter section is 40 acres. Actual surveyed acreage can vary because of corrections, water, irregular boundaries, and government lots.
How do you read an aliquot description?
Locate nested fractions from the section into successively smaller parts. For the NE 1/4 of the SW 1/4, first find the southwest quarter, then its northeast quarter. The written wording names the smallest subdivision first. Reversing those directional labels can identify different land even when the nominal area stays 40 acres.
How does lot and block identify a parcel?
It identifies the lot and any block by reference to the named recorded subdivision plat. Some subdivisions have lots without blocks. Check the recording references, dimensions, easements, notes and other applicable title records. A lot number alone, or a generic reference to an unrecorded drawing, is not the same complete identification. Condominium-unit identification has its own statutory provision.
Is a street address a legal description?
A street address is primarily a location or mailing identifier, and a PIN indexes a tax parcel. Neither is one of these three boundary-description methods. Use them to cross-check the intended land, including multiple parcels under one address. Whether particular contract wording is legally sufficient is a separate legal question; do not infer every instrument's validity from an exam label.
Can a real estate broker write a new boundary description?
Accurately copying or communicating an existing description differs from creating or revising one that determines title or real property rights through boundary lengths and directions. Section 5 of the Illinois Professional Land Surveyor Act includes that preparation and boundary determination in professional land surveying. A real estate license alone does not authorize it. Refer a new or disputed boundary to the appropriate professionals.
Are these official PSI exam questions?
No. These are original teaching questions supporting PSI National I.B.1-3 and Illinois III.E in the June 24, 2026 outline. Identified Illinois provisions and BLM guidance support the explanations. The practice is not a validated passing prediction or professional approval of a description.
Does Illinois require every description to close mathematically?
Rule 1270.56(g) requires a complete, definite, locatable description and mathematical closure when appropriate. Its (g)(4) exception concerns descriptions for other purposes that define neither conveyance boundaries nor survey extent; those descriptions need not relate to a physically monumented corner. A center-line strip and a closed parcel perimeter also need different checks. These qualifications do not authorize incomplete or ambiguous descriptions.
Is a government lot the same as a lot in a subdivision?
No. Government lots belong to the public survey records and often accommodate irregular areas. Subdivision lots are identified by their subdivision plat. Check the complete references and actual record acreage rather than converting every numbered lot into a standard aliquot fraction.
Can actual section acreage simply be divided to find an aliquot part?
Not necessarily. Nominal exam fractions use the stated standard model. Actual aliquot boundaries follow survey subdivision principles, which do not always produce equal areas. An actual section total alone may not establish the acreage of a named quarter or half; use the survey evidence for that tract.
How are Illinois condominium units legally identified?
Section 7 of the Condominium Property Act permits the unit's identifying number or symbol as shown on the plat and set forth in the declaration. The statutory description also affects the corresponding common-element ownership even if not expressly repeated. Verify the intended unit and associated interests; do not substitute a mailing number or assume parking and storage rights from the address.
What does the Illinois PIN provision actually cover?
Conveyances Act Section 35d addresses a grantor of residential property providing matching PINs or the specified alternatives to the grantee in a county with 3,000,000 or more inhabitants. It is not a universal rule that a PIN replaces the legal description. The section addresses continuing liability for noncompliance and expressly preserves deed validity despite failure to provide the PINs. Other recording requirements can apply separately.
Does a metes-and-bounds defect automatically void an Illinois deed?
Do not assume so. Section 35c specifies information for recorded conveyance descriptions and says neglect to comply with that section does not invalidate the instrument. That does not approve every ambiguous description or guarantee what land a disputed deed conveys. Flag the issue for qualified survey and legal review rather than declare it harmless or automatically void.
What does Plat Act Section 1.02 concern?
It addresses plats for annexation or disconnection of territory by the specified governmental bodies, including sufficient boundary identification and the stated preparation and filing requirements. It is not a general rule approving every private conveyance description. Private subdivision requirements are addressed elsewhere, including Section 1 and its exceptions.
Does writing a new description make a subdivision lawful?
No. A description identifies land; it does not by itself satisfy subdivision, approval or recording requirements. Plat Act Section 1 has a general subdivision trigger, exceptions and provisions about exempt plats, while local requirements can also matter. Get qualified advice on the actual division instead of assuming a metes-and-bounds description avoids the Plat Act.
Can a map or GIS line settle the boundary?
Do not assume so. USGS says PLSS lines represented on US Topo maps are not legally authoritative. A locator map or tax display can help find records, but a boundary determination requires the appropriate records, survey evidence and law. Do not replace that work with a line displayed on a screen.
