Co-Owned Buildings & Strata Titles: Statutory Mechanics of Foreign Ownership Under the 2010 Law and Sub-Decree No. 82

Word Count Target: ~1,500 words

Core Themes: The 2010 Foreign Ownership Law (Royal Kram No. NS/RKM/0510/006); Sub-Decree No. 82 ANKr.BK; The 70% aggregate foreign ownership quota; The ground floor/underground prohibition; Special border zone exclusions; Strata title (Vicheanapat Samroab) registration workflows; Common property governance vs. private unit ownership.

Until 2010, the constitutional prohibition enshrined in Article 44 of the 1993 Constitution effectively locked cross-border individual capital out of direct, titled real estate ownership in Cambodia. While commercial enterprises operated via long-term leases or corporate holding structures, individual foreign investors possessed no statutory mechanism to secure absolute, perpetual, state-backed title over residential or commercial real estate.

This structural barrier changed with the promulgation of the Law on Providing Foreigners with Ownership Rights in Private Units of Co-Owned Buildings (promulgated by Royal Kram No. NS/RKM/0510/006 on May 24, 2010; commonly cited as the Foreign Ownership Law of 2010), along with its operational administrative regulation, Sub-Decree No. 82 ANKr.BK on Determining the Ratio and Calculation of Private Units That Can Be Owned by Foreigners in a Co-Owned Building (dated July 29, 2010).

Together, these legislative enactments introduced the concept of Strata Title (Vicheanapat Samroab) to the Cambodian legal system, creating a segmented real-property framework that harmonized direct foreign ownership rights with the fundamental constitutional ban on foreign landholding.

The Legal Architecture of the “Co-Owned Building”

To permit foreign ownership without violating Article 44 of the Constitution, the 2010 Law detached ownership of specific, demarcated vertical volumes of physical space from the ownership of the underlying land plot.

Under Article 2 of the 2010 Law, a Co-Owned Building (Akar Samroab) is defined as any building or construction where multiple owners hold:

1. Private Units (Phnek Ekachon), consisting of individual spaces exclusively owned, occupied, and utilized by specific titleholders; and

2. Common Areas (Phnek Ruom), consisting of structural elements, architectural foundations, shared utility passages, corridors, stairwells, roofs, and—most importantly—the underlying land parcel upon which the building sits.

Under this legal demarcation, the underlying land remains an indivisible, common property asset. Foreigners do not acquire a direct or severable freehold interest in the soil. Instead, foreign titleholders obtain a specialized certificate of private unit ownership: an individualized cadastral title that confers perpetual, alienable, inheritable, and mortgagable real rights over the interior air-space and interior partitions of their specific unit, combined with an undivided, proportionate percentage share in the administration of the common property.

The Core Statutory Restrictions on Foreign Strata Title Ownership

The Foreign Ownership Law of 2010 and Sub-Decree No. 82 impose four structural limitations designed to safeguard national security, sovereign border integrity, and the constitutional land monopoly:

+----------------------------------------------------------------------------------+
|                    STATUTORY FOREIGN STRATA RESTRICTIONS                         |
+------------------------------------+---------------------------------------------+
| 1. The 70% Floor-Area Cap          | Max 70% of total private unit surface area  |
| 2. Ground Floor Exclusion          | Absolute ban on Ground Floor & Underground  |
| 3. Border Buffer Zone Exclusion    | Prohibited within 30 km of national borders |
| 4. Master Land Title Prerequisite  | Parcel MUST hold an official Hard Title     |
+------------------------------------+---------------------------------------------+

1. The 70 Percent Surface-Area Quota (Article 6 of Sub-Decree No. 82)

The law does not permit foreign entities to acquire an entire residential tower. Under Article 6 of Sub-Decree No. 82, the maximum aggregate private floor space across an entire co-owned building that can be transferred into foreign ownership is capped at 70 percent.

The mechanics of this quota are calculated strictly according to net private living area:

• The Denominator: The aggregate sum of the surface area (measured in square meters) of all registered private units in the building.

• The Exclusions: Common areas (corridors, elevator shafts, service rooms, lobbies, recreational decks, and utility floors) are excluded from both the numerator and denominator.

• The Compliance Mechanism: Once the cumulative square meterage transferred to foreign physical or legal entities reaches 70 percent of the total private unit surface area, the General Department of Cadastre and Geography within the Ministry of Land Management, Urban Planning and Construction (MLMUPC) automatically locks the building’s cadastre. Any subsequent conveyances, transfers, or long-term lease conversions for the remaining 30 percent of private unit space may strictly be issued only to physical persons holding Cambodian nationality or legal entities meeting the definition of a Khmer Legal Entity under Article 56 of the 2001 Land Law.

2. The Absolute Exclusion of Ground Floors and Subterranean Levels

Under Article 6 of the 2010 Law, foreigners are barred from holding ownership rights in:

• The Ground Floor (Bantoap Choan Phkhal Dei); and

• Any Underground Floor (Choan Kraom Dei).

The statutory intent of this exclusion is direct: because the ground floor rests immediately upon the terrain, direct private ownership of the ground level could be construed under civil property theory as direct, exclusionary possession of the national soil, which would breach Article 44 of the Constitution. Consequently, all ground floors, basements, subterranean parking complexes, foundation levels, and structural footings must remain either:

• Designated as statutory common property managed by the co-owners’ association; or

• Titled exclusively to Cambodian citizens or 51% Cambodian-owned domestic corporations.

Foreign strata ownership may legally commence only on the first floor above the ground floor (which, under French architectural notation standard in Cambodia, is designated as Premier Étage, situated immediately above the Rez-de-chaussée) and extends upward through the tower’s penthouse levels.

3. Geographical Exclusions: The 30-Kilometer Border Buffer

Under Article 13 of the 2010 Law and administrative provisions established by the Royal Government, co-owned buildings situated within designated border buffer zones are entirely excluded from foreign strata ownership.

Foreigners cannot purchase strata units in co-owned buildings located within 30 kilometers of land borders with the Kingdom of Thailand, the Lao People’s Democratic Republic, or the Socialist Republic of Vietnam.

The law provides limited exceptions:

• Urban centers or capital districts of border provinces designated by special Royal Decrees;

• Specially demarcated Special Economic Zones (SEZs); and

• Specifically approved, state-sanctioned Master Planned Urban Development Zones where the Council of Ministers formally grants an exemption based on economic investment necessity.

4. Master Title Requirements: The Hard Title Prerequisite

A foreign strata title cannot be created out of an informal, unregistered, or “soft” titled property parcel. Article 7 of the 2010 Law mandates that the co-owned building must be erected upon land held under a definitive, registered Hard Title (either an LMAP Certificate of Immovable Property Title or a Sporadic Cadastral Certificate). If a developer holds land only under local commune-level possessory papers (Plon Tromung or soft title), the MLMUPC will not permit the subdivision of the property into strata units.

The Administrative Workflow of Strata Title Subdivision

For a foreign investor to acquire a legally enforceable, state-guaranteed strata title deed, the development project must complete an exhaustive multi-stage titling progression administered by the MLMUPC:

+-----------------------------------------------------------------------------------+
|                     STRATA TITLING CONVERSION WORKFLOW                            |
+-----------------------------------------------------------------------------------+
  [Stage 1: Master Hard Title]
         |  Developer must hold definitive ownership over the underlying land plot.
         v
  [Stage 2: Construction & Architectural Approval]
         |  Permits from MLMUPC verifying compliance with Building Law (2019).
         v
  [Stage 3: Application for Co-Owned Status]
         |  Filing with Cadastral Office to transform single-plot title into Co-Owned.
         v
  [Stage 4: Cadastral Survey & Boundary Delimitation]
         |  Cadastre measures 3D unit dimensions, common areas, and calculates 70% cap.
         v
  [Stage 5: Issuance of Strata Titles (Vicheanapat Samroab)]
         |  Individual titles issued; foreign transfers registered with 4% stamp tax.
+-----------------------------------------------------------------------------------+

1. Master Hard Title Verification: The project site must possess an unencumbered Hard Title issued by the relevant Municipal/Provincial Cadastral Office.

2. Construction and Architectural Approval: The developer must secure an official Construction Permit (Chhbab Anounhoat Sangsong) and a Site Opening Permit from the MLMUPC, proving structural compliance under the Law on Construction (2019).

3. Application for Co-Owned Status: Prior to or upon completion of construction, the developer files an application to transform the single-plot cadastral asset into a multi-unit co-owned property.

4. Cadastral Boundary Delimitation & Internal Surveying: Cadastral survey teams map the physical vertical boundaries of every individual unit, demarcating the common utility corridors, fire escapes, vertical shafts, and perimeter boundaries. The exact net floor surface area of every private unit is calculated, recorded, and indexed in the national land registry.

5. Issuance of Master Strata Register and Unit Deeds: The MLMUPC cancels the standalone status of the original master land title and creates the Co-Owned Building Register. For each private unit, the Cadastral Office generates an individual Certificate of Private Unit Ownership (Vicheanapat Samroab). Each title contains the unit’s unique cadastral identification code, its exact cubic-dimensional layout, floor level, total net area, and its allocated percentage of common property ownership.

Legal Status of the Strata Deed: Commercial Capabilities

A registered Strata Title confers upon the foreign holder full civil rights within the boundaries of Cambodian property law. Under Chapter 3 of the 2010 Law, a foreign titleholder possesses the autonomous legal authority to:

• Sell, assign, or convey the unit to any foreign or domestic party (provided foreign transfer does not violate the building’s overall 70% foreign cap);

• Register a Hypothec (Mortgage): The strata title can be pledged as formal collateral to domestic or international commercial banks licensed under the National Bank of Cambodia (NBC);

• Lease the Real Property: Foreign owners may enter into short- or long-term commercial lease agreements, collecting market rental yields without state intervention; and

• Devise and Bequeath: The unit forms part of the owner’s lawful estate and may be transferred to designated heirs via probate or testamentary disposition.

Pitfalls in the Market: Soft Titles and De Facto Common Areas

Foreign buyers often encounter developments marketed with promises of future strata titles that never materialize. A common structural failure occurs when an off-plan development is marketed on a soft title parcel. If the master developer fails to settle municipal land-conversion fees, lacks statutory permits, or defaults on an underlying bank lien secured against the master land title, the Cadastral Office will refuse to register the subdivision.

In such scenarios, foreign buyers are left with unrecorded, purely contractual private sales agreements (Samreang Luok-Ting). In Cambodian courts, these private instruments do not constitute property deeds; they function merely as unsecured, personal contractual claims against the developer. If the developer becomes insolvent, the foreign buyer has no title claim against the land or unit.

Securing an authentic, state-issued Certificate of Private Unit Ownership certified by the MLMUPC is the only mechanism that protects foreign capital with direct, inalienable real property rights under the 2010 statutory framework.
