Demystifying the Lot and Block Survey System for the Hawaii Real Estate Exam

Last updated: April 2026

Navigating legal property descriptions is a fundamental skill for any aspiring real estate professional. For candidates preparing for the Hawaii real estate licensing exam, understanding the Lot and Block survey system (also known as the recorded plat system) is absolutely essential. Because Hawaii features a unique dual-recording system and distinct historical land laws, the way subdivisions are recorded and legally described here differs slightly from the mainland.

This guide will break down the lot and block system, explain how it interacts with Hawaii’s Regular System and Land Court, and provide practical examples to ensure you are fully prepared for exam day. For a broader overview of all exam topics, be sure to bookmark our Complete Hawaii Exam Guide.

What is the Lot and Block Survey System?

The lot and block system is a method used to legally describe property, primarily in densely populated urban, suburban, and subdivided areas. It is designed to simplify the identification of individual parcels of land within a larger tract.

The process works sequentially:

  1. Initial Survey: A large parcel of land is first surveyed using Hawaii metes and bounds legal descriptions to establish the perimeter of the entire parent tract.
  2. Subdivision: The developer or surveyor divides the large parcel into smaller, manageable sections called blocks.
  3. Individual Parcels: Those blocks are further subdivided into individual lots (the actual parcels sold to buyers).
  4. Plat Map Recording: The surveyor creates a detailed map, known as a plat map or subdivision map, illustrating the exact dimensions, streets, easements, and lot/block numbers. This map is then officially recorded with the government.

The Hawaii Context: Regular System vs. Land Court

To pass the Hawaii real estate exam, you must demonstrate expertise in Hawaii's dual recording systems. The way a lot and block description is officially recorded depends on which system the land falls under.

The Regular System (Bureau of Conveyances)

Governed by Hawaii Revised Statutes (HRS) Chapter 502, the Regular System is a "race-notice" recording system. When a developer subdivides Regular System land, they file a File Plan (FP) with the Bureau of Conveyances.

A legal description in the Regular System utilizing lot and block will typically reference the specific File Plan number. For example: "Lot 14, Block B, of the 'Sunset Estates' subdivision, as shown on File Plan No. 4321, recorded in the Bureau of Conveyances of the State of Hawaii."

The Land Court System (Torrens System)

Governed by Hawaii Revised Statutes (HRS) Chapter 501, the Land Court system guarantees the title to the property. When Land Court property is subdivided, a consolidation and resubdivision map is filed directly with the Land Court. Instead of a File Plan, the property will reference a specific Map Number and Transfer Certificate of Title (TCT).

A Land Court legal description might read: "Lot 45, as shown on Map 12, filed in the Office of the Assistant Registrar of the Land Court of the State of Hawaii with Land Court Application No. 888." Notice that Land Court descriptions often drop the "Block" designation and simply rely on sequential Lot numbers tied to specific Map numbers.

Visualizing Legal Descriptions in Hawaii

While the lot and block system is the standard for subdivisions, it is not the only method used in the islands. The chart below illustrates the approximate prevalence of different legal description frameworks utilized in modern Hawaii real estate transactions.

Lot and Block vs. Tax Map Key (TMK)

A frequent trap for test-takers is confusing the legal description (Lot and Block) with the Tax Map Key (TMK).

The TMK is a 9-digit number used by county tax assessors to identify property for property tax purposes. Its format is: Division - Zone - Section - Plat - Parcel - CPR (if applicable). While a TMK plat map will visually show the lots and blocks of a subdivision, the TMK itself is not the legal description. A valid real estate contract in Hawaii requires the actual legal description (the Lot/Block/File Plan or Land Court Map data), though the TMK is always included for administrative clarity.

Practical Scenario for the Exam

Imagine a scenario where a client is buying a beachfront lot in a newly developed subdivision in Kailua. The boundaries of the lot might be subject to state shoreline regulations, meaning you must also understand Hawaii water rights and riparian law. The initial developer bought a 10-acre parcel (described by metes and bounds), subdivided it into 20 lots, and filed a File Plan. Your client's deed will describe the property as "Lot 5 of File Plan 9988," rather than spelling out the metes and bounds of that individual 0.5-acre lot.

Study Strategies for Legal Descriptions

Memorizing the nuances between Regular System File Plans and Land Court Maps can be tricky. We highly recommend utilizing spaced repetition for exam prep to drill these concepts into your long-term memory. Create flashcards distinguishing HRS 501 (Land Court) from HRS 502 (Regular System), and test yourself on drafting mock legal descriptions.

Frequently Asked Questions (FAQs)

1. What is the main difference between a File Plan and a Land Court Map?

A File Plan is a subdivision map recorded in the Regular System (Bureau of Conveyances) under HRS Chapter 502. A Land Court Map is filed with the Office of the Assistant Registrar of the Land Court under HRS Chapter 501 and is backed by a Transfer Certificate of Title (TCT) which guarantees ownership.

2. Can a property have both a lot and block description and a metes and bounds description?

Yes, historically. The perimeter of the entire subdivision is always described by metes and bounds. Furthermore, sometimes an individual lot's deed will recite the metes and bounds of that specific lot in addition to referencing the recorded lot and block plat map, though the lot/block reference alone is legally sufficient.

3. Is the Tax Map Key (TMK) considered a legal property description in Hawaii?

No. The TMK is an administrative number created by the county for property tax assessment purposes. While heavily used in real estate listings and contracts, the actual legal description relies on the recorded plat map (Lot and Block) or a metes and bounds survey.

4. Where are subdivision plat maps physically recorded in Hawaii?

All property records in Hawaii, whether Regular System or Land Court, are recorded centrally at the Bureau of Conveyances located in Honolulu on the island of Oahu. Hawaii is unique in that it does not have county-level recording offices.

5. How does the lot and block system apply to Condominium Property Regimes (CPRs)?

When a developer creates a CPR (condominium), the underlying land is usually described using the lot and block system (e.g., Lot 12 of a specific File Plan). The CPR declaration then further divides that specific lot into 3D spatial units (apartments/condos) or spatial land units, assigning them specific CPR numbers.
