Understanding Metes and Bounds and Land Descriptions in Hong Kong
Last updated: April 2026
If you are preparing for the Estate Agents Authority (EAA) Salesperson Qualifying Examination (SQE), having a solid grasp of how land is legally described and measured is crucial. While you may encounter the traditional common law concept of "metes and bounds" in your studies, it is equally important to understand how this concept translates to the unique land registration and surveying framework of Hong Kong. For a comprehensive overview of the exam, be sure to check out our Complete Hong Kong Salesperson Exam Exam Guide.
In this mini-article, we will break down the fundamental principles of metes and bounds legal descriptions, explore how land boundaries are officially defined in Hong Kong under the Land Survey Ordinance, and discuss practical scenarios you will face as a licensed estate agent.
What is a Metes and Bounds Legal Description?
The "metes and bounds" system is one of the oldest methods used in common law jurisdictions to describe land, real property, and real estate. The term itself can be broken down into two components:
- Metes: Refers to the measurement of distance and direction (e.g., "North 45 degrees East for 150 feet").
- Bounds: Refers to the physical features or landmarks that define the boundaries of the property (e.g., "along the center line of the stream" or "to the old oak tree"). These are often called monuments.
A true metes and bounds description always starts at a specific, identifiable location known as the Point of Beginning (POB). The description then traces the perimeter of the property using distances, angles, and landmarks, eventually returning to the exact same Point of Beginning to create an enclosed area.
The Hierarchy of Evidence
In the event of a discrepancy in a traditional metes and bounds description, courts generally follow a hierarchy of evidence to determine the true boundary. Natural monuments (like rivers or large boulders) take the highest precedence, followed by artificial monuments (like iron pins or concrete markers), then adjacent boundaries, courses (directions), and finally, distances and area.
How Land is Described in Hong Kong
While the traditional "metes and bounds" terminology is highly prevalent in the United States and parts of the UK, Hong Kong utilizes a highly systematized lot numbering system managed by the Lands Department and the Land Registry. However, the principles of metes and bounds—relying on physical markers and precise measurements—are deeply embedded in Hong Kong's land history, particularly in the New Territories.
The Demarcation District (DD) System
When the British leased the New Territories in 1898, a massive land survey was conducted between 1899 and 1904 to record land ownership for taxation purposes. The land was divided into Demarcation Districts (DD). The surveyors at the time used rudimentary plane table surveys, marking boundaries based on physical "bounds" such as field bunds, village paths, and streams.
Today, a piece of land in the New Territories is legally described using its DD and Lot number (e.g., Lot 123 in DD 104). In urban areas like Hong Kong Island and Kowloon, land is described using Inland Lots (IL) or Kowloon Inland Lots (KIL) (e.g., Kowloon Inland Lot No. 4567).
Modern Boundary Surveys and Cap. 473
Because the original 1905 Block Government Leases in the New Territories relied on physical bounds that may have eroded or shifted over the last century, boundary disputes are common. Today, the Land Survey Ordinance (Cap. 473) governs the registration and discipline of Authorized Land Surveyors (ALS).
When a boundary needs to be re-established or a lot needs to be subdivided, an ALS must conduct a land boundary survey. They will search for old boundary stones (artificial monuments) and compare them against the Survey and Mapping Office (SMO) records, effectively applying modern metes and bounds principles using advanced GPS and total station technology.

Practical Scenarios for Hong Kong Estate Agents
As an estate agent in Hong Kong, you are not expected to be a land surveyor. However, the EAA Code of Ethics requires you to provide accurate information and avoid misrepresentation. Understanding land descriptions is vital for several reasons.
1. Village House Transactions in the New Territories
If you are representing a seller of a village house (Ding House), the property boundaries might not be clearly fenced. The actual legal boundary (the "bounds") might differ from the physical garden wall built by the owner. If you misrepresent the size of the garden, you could be liable for misrepresentation. You must advise the purchaser that the exact boundaries can only be confirmed by an Authorized Land Surveyor. Adhering to these honest disclosure practices is a core part of real estate ethics and standards.
2. Property Size and Valuation
The exact area of a lot, determined by its legal boundary description, directly impacts its valuation, plot ratio calculations, and Government rent. If a portion of the land is found to be encroaching on Government land, the buyer may face enforcement action from the Lands Department. Furthermore, accurate land size is essential when you are performing proration calculations step-by-step for property taxes, management fees, or government rents during the completion of a sale.
3. Recommending Professionals
If a client asks you to recommend a land surveyor to clarify a metes and bounds discrepancy, you must provide independent recommendations. Remember that colluding with other agencies or surveyors to fix service fees is strictly prohibited. You must always be mindful of anti-trust laws in real estate when dealing with third-party service providers.
Key Takeaways for the SQE Exam
- Definition: Metes refer to distances and directions; bounds refer to physical landmarks or monuments.
- Point of Beginning (POB): A metes and bounds description must start and end at the exact same point to form a closed polygon.
- Hong Kong Context: HK primarily uses Lot Numbers (IL, KIL, DD Lots) rather than written metes and bounds descriptions in its Land Registry deeds, but relies on Authorized Land Surveyors to translate those lot numbers into physical boundaries.
- Agent Responsibility: Never guarantee a boundary line based on physical fences. Always rely on land registry plans and advise clients to hire an Authorized Land Surveyor if boundaries are in doubt.
Frequently Asked Questions (FAQs)
1. Does the Hong Kong Land Registry use metes and bounds descriptions?
Not typically in the written text of modern deeds. Hong Kong uses a system of Lot Numbers (such as Inland Lots or Demarcation District Lots) combined with official survey plans deposited with the Land Registry and the Survey and Mapping Office (SMO). However, the principles of metes and bounds are used by surveyors to establish these plans.
2. What happens if the physical "bounds" (like a fence) do not match the official Land Registry plan?
The official boundary defined by the land grant and subsequent registered survey plans takes precedence. If a physical fence encloses Government land or a neighbor's land, it is considered an encroachment. Purchasers should be warned of potential liability.
3. What is an Authorized Land Surveyor (ALS) in Hong Kong?
An ALS is a professional registered under the Land Survey Ordinance (Cap. 473). They are the only professionals legally authorized to conduct land boundary surveys for the subdivision of land and to officially determine lot boundaries in Hong Kong.
4. Why are Demarcation District (DD) sheets sometimes inaccurate?
DD sheets were created over a century ago (around 1900) using basic plane table surveying methods. The scale was small (often 1:3960), and the physical bounds used at the time (like mud bunds between rice paddies) have long since disappeared, leading to modern discrepancies.
5. Can an estate agent measure the property boundary for a client?
No. While an agent can provide the Saleable Area (SA) of a residential unit based on the Rating and Valuation Department or first-hand sales brochures, establishing external land boundaries is strictly the purview of an Authorized Land Surveyor. Attempting to define legal boundaries for a client is a breach of professional EAA guidelines.
