Land is one of the most valuable assets in Cambodia, whether for individuals, families, businesses, or investors. As Cambodia continues to experience economic growth, urban expansion, and increased real estate development, disputes concerning land ownership and boundaries have become increasingly common. Among the most frequent types of land conflicts are boundary disputes, which arise when neighboring landowners disagree about the location, size, or limits of their respective properties.
A boundary dispute may occur because of unclear land descriptions, inaccurate measurements, missing boundary markers, informal land transfers, overlapping claims, or differences between actual occupation and official land records. These disputes can affect residential properties, agricultural land, commercial developments, and construction projects.
Understanding the legal process is essential for landowners and investors to protect their property rights and avoid costly and lengthy disputes. 

The foundation of land rights in Cambodia is established under the Land Law 2001, which regulates ownership, possession, land registration, and the administration of land resources.
According to Article 4 of the Land Law 2001, the ownership of immovable property is protected by law, and land rights must comply with the provisions established under Cambodian legislation. The law recognizes legally registered land ownership as the strongest form of land entitlement.

 
Under Article 6 of the Land Law 2001, all persons may possess and own land only in accordance with Cambodian law. Land ownership rights are generally recognized through a legal title issued by competent authorities.
The Land Law also establishes the importance of cadastral registration. Under Article 229 of the Land Law 2001, the cadastral system is responsible for identifying land parcels, recording ownership information, and maintaining official land records. These cadastral records play an important role when determining the legal boundary of a property. 

The Civil Code of Cambodia, which entered into force in 2011, also provides general principles regarding ownership and immovable property rights. Under Article 138 of the Civil Code, ownership is defined as the right to use, enjoy benefits from, and dispose of property within the limits permitted by law.
Therefore, when a boundary dispute occurs, Cambodian authorities and courts generally consider official land titles, cadastral maps, survey records, and other evidence proving ownership and possession.

Boundary disputes in Cambodia commonly arise from historical, administrative, and practical issues relating to land use.
One major cause is the difference between physical occupation and official land records. In some areas, especially rural communities, families may have occupied land for many years based on traditional boundaries such as trees, fences, roads, or natural landmarks. However, when formal land registration occurs, the official survey may identify different boundaries.
Another common issue is the absence or movement of boundary markers. Cambodian land registration relies on cadastral surveys and boundary markers placed by competent authorities. If markers are removed, damaged, or relocated without authorization, neighboring owners may disagree about the correct property line.

 
Boundary disputes may also occur after informal land transactions. Some land transfers are conducted through private agreements without proper registration with relevant authorities. As a result, buyers may later discover overlapping claims or uncertainty regarding the exact boundaries of the purchased land. 

Inheritance is another frequent source of boundary conflicts. When family property is divided among heirs without proper measurement and registration, disagreements may arise regarding which portions belong to each heir.
In urban areas, boundary disputes are often connected with construction activities. Building extensions, walls, fences, or structures constructed beyond the legal boundary may result in conflicts between neighboring property owners. 

The first step in resolving a boundary dispute in Cambodia is usually to verify the official land information maintained by cadastral authorities.
The Ministry of Land Management, Urban Planning and Construction (MLMUPC) is responsible for land administration, urban planning, and cadastral management. Through cadastral offices, authorities maintain records of land parcels, ownership information, and survey documentation.
When a boundary disagreement occurs, parties may request a cadastral inspection or survey to determine the actual location of the property boundary. Officials may examine:

-Land titles
- Cadastral maps
- Survey measurements
- Boundary markers
- Historical land records

Statements from relevant parties or neighboring landowners.
A cadastral determination can help clarify whether the dispute resulted from incorrect assumptions, inaccurate measurements, or overlapping claims.
However, cadastral authorities generally determine technical land boundaries based on official records and surveys. If the dispute involves complex ownership claims, fraud allegations, or competing legal rights, the matter may need to be resolved through mediation or court proceedings. 

Cambodian law encourages parties to resolve land disputes through peaceful settlement whenever possible. Negotiation and mediation are often faster and less expensive alternatives compared with litigation.
For neighboring landowners, direct negotiation may involve reviewing land documents, conducting joint inspections, and agreeing on a mutually acceptable boundary.

Local authorities, including commune and district officials, may also assist parties in resolving disputes through administrative mediation. The Law on Commune/Sangkat Administrative Management recognizes the role of local authorities in addressing certain community-level disputes.
In addition, the National Authority for Land Dispute Resolution (NALDR) has historically played a role in addressing land disputes outside the court system. Mediation mechanisms can help preserve relationships between neighbors and avoid lengthy legal proceedings. 

A written settlement agreement is recommended when parties reach an agreement. The agreement should clearly describe the boundary, obligations of each party, and any commitments regarding future use of the land. Where necessary, parties should register changes with competent land authorities to ensure legal recognition. 

When negotiation and administrative solutions fail, a party may bring a claim before the competent Cambodian court.
Under Cambodian civil procedure, a person whose property rights are affected may seek judicial protection. The court may examine evidence including land titles, cadastral documents, contracts, witness testimony, expert opinions, and survey results.
The Cambodian Civil Code provides protection for ownership rights. Under Article 158 of the Civil Code, an owner has the right to demand the return of property from a person unlawfully possessing it. This principle may apply where a neighboring party occupies land beyond the legally recognized boundary.
Additionally, under Article 159 of the Civil Code, an owner may seek removal of interference with ownership rights. This may be relevant where a person constructs a building, fence, or other structure that crosses into another person's land.
During court proceedings, the court may order additional examination, including expert land measurement or technical assessment, to determine the correct boundary.

Possible remedies may include:

- Recognition of the legally established boundary
- Removal of unauthorized structures
- Compensation for damages
- Restoration of possession

Court proceedings may take significant time depending on the complexity of the dispute, availability of evidence, and appeals. Therefore, proper legal preparation is important before filing a claim. 

Many boundary disputes can be avoided through proper legal due diligence before purchasing land.
Before entering into a land transaction in Cambodia, buyers should verify:

1. Whether the seller has valid ownership documents
2. Whether the land title is properly registered
3. Whether the cadastral map matches the physical property
4. Whether neighboring claims exist
5. Whether there are restrictions or disputes affecting the property.

Cambodia has made significant progress in land registration through systematic land registration programs. According to the Ministry of Land Management, Urban Planning and Construction, millions of land titles have been issued through Cambodia’s land registration programs, improving legal certainty for landowners. However, because land registration has developed gradually over time, disputes involving historical possession and unclear boundaries continue to occur in some areas.
For investors and developers, professional legal review before acquiring land can significantly reduce risks associated with boundary conflicts, construction delays, and ownership disputes. 

Boundary disputes in Cambodia are complex matters involving land ownership rights, cadastral records, and legal procedures. Cambodian law provides several mechanisms for resolving these disputes, beginning with verification through cadastral authorities and extending to negotiation, mediation, and court proceedings.
The strongest protection for landowners is maintaining accurate land registration documents, conducting proper due diligence before transactions, and seeking legal advice when disputes arise. By understanding the legal framework under the Land Law 2001, the Civil Code of Cambodia, and relevant land administration regulations, individuals and businesses can better protect their property rights and resolve boundary conflicts effectively.
