Metal Detecting Laws in Cambodia

Cambodia places archaeological searching within an authorized scientific-research regime, including systematic surface searches. This does not settle whether you may use a detector solely to look for modern lost items. What you find also matters: cultural discoveries and ordinary lost property have different ownership and reporting rules.

The rules, land by land

Even where detecting is allowed, archaeological and historic sites are protected, and you must fill every hole and follow posted rules. Always confirm the current rule with the land manager.

Archaeological searching and permits

The អនុក្រឹត្យលេខ ៩៨ (Subdecree No. 98) defines archaeological work broadly in Article 17: it includes research to discover archaeological objects or study archaeological material or sites, including systematic exploration of the ground surface. The definition also reaches work on the bed or subsoil of inland and territorial waters. This is a search restriction, not just an excavation rule.

The 1996 ច្បាប់ស្តីពីកិច្ចការពារបេតិកភណ្ឌវប្បធម៌ (Law on the Protection of Cultural Heritage) requires prior authorization for heritage excavations or surveys. Article 41 reserves archaeological work to recognized scientific institutions with the necessary expertise, experience and resources. Subdecree No. 98 provides an institutional permit route with a scientific program. These provisions do not establish a hobby permit or general permission to search for modern lost objects.

Protected monuments and archaeological sites

The scientific-authorization requirement applies to archaeological searching at protected monuments and sites. Heritage Law Article 23 separately requires authorization before classified cultural property, or property proposed for classification, is moved, destroyed, modified, altered, repaired or restored.

Subdecree No. 98 contains special exclusions and arrangements for active religious sites and cemeteries in Article 22. An archaeological permit therefore does not provide blanket permission to work at every protected place.

Beaches, state forests and private land

The national archaeological-search regime applies on beaches and foreshore, in state forests and on private land. It does not establish general permission in those places to search solely for modern lost objects or recover detector targets. Protected-area zoning can also restrict access to forests within those areas.

For archaeological work on private land, Subdecree No. 98 requires the owner to be informed during review of an excavation application and notified of the permit. Owning the land does not replace the archaeological authorization. Rules for sharing a buried find do not authorize entering land, searching it or digging.

National parks and nature reserves

Archaeological searching in national parks and nature reserves remains subject to scientific authorization. The ក្រមបរិស្ថាននិងធនធានធម្មជាតិ (Code on Environment and Natural Resources) also imposes access restrictions. Article 364(3) excludes areas designated to and managed by APSARA Authority or other authorities entrusted by the Royal Government from these natural protected areas. Within that scope, under Article 364, entry to a core zone is prohibited except for officials responsible for protected-area management performing their duties, authorized natural-science researchers for the specified conservation purposes, and necessary security or defense activity.

Within the same territorial scope, entry to a conservation zone requires prior authorization from the responsible protected-area officials, subject to the security and defense exception. Permission to enter does not itself authorize detecting or excavation. A general park permission to search for modern lost objects or recover targets could not be confirmed. The exclusion does not establish detecting permission or displace the separate national archaeological-authorization requirements.

The 2023 code displaces the 2008 Protected Areas Law from the code’s application; Article 865 provides for application one year after entry into force. The access provisions described here are those of the newer code.

Cultural discoveries: report promptly and do not claim ownership

Under Heritage Law Article 37, when construction or another activity reveals cultural property of the kinds covered by that article, both the finder and the owner of the discovery site must stop the construction work and immediately declare the discovery to local police. Police pass the declaration without delay to the province or city governor, as applicable, who informs the competent authority and takes protective measures.

The ក្រមរដ្ឋប្បវេណី (Civil Code) treats underground statues, bas-reliefs, antiquities and other cultural objects as state property. Article 141 requires the landowner to deliver them to the Ministry of Culture and Fine Arts. Heritage Law Article 39 makes movable cultural property discovered by chance public property and provides a reward within three weeks of discovery, with the amount fixed by agreement or expert opinion.

Objects found by scientific institutions are also state property under Heritage Law Article 44. Its limited donation exception concerns duplicate objects or objects not essential to public collections, donated to scientific institutions for public display. It gives hobby finders no right to keep artifacts.

In natural protected areas, Environmental Code Article 411 requires people who know of or chance upon suspected cultural objects, ancient structures or other ancient objects during activities to report urgently to the relevant ministries or institutions and subnational administration. Under Article 412, a chance finder during excavation, digging, construction or another activity must temporarily stop the work, report, and immediately send the cultural property to subnational administration or the relevant competent institution. The following articles set out official reporting, assessment and suspension procedures.

Ordinary lost objects and buried treasure

Civil Code Article 191 requires a finder to return an ordinary lost object to its known owner. If the owner is unclear, hand it to the chief of the police post within seven days of finding it. That seven-day period does not replace the immediate reporting duty for heritage discoveries.

The police keep the object and give public notice. If no owner is identified within six months, the finder acquires ownership. A finder who fails to hand it in within seven days cannot acquire it; it becomes state property instead. The same result follows if the finder does not collect it within two months after acquiring ownership.

Article 192 applies the lost-object rules to buried treasure, subject to Article 141’s separate treatment of cultural objects and minerals. Where unclaimed treasure is found within another person’s property, the finder and that property’s owner share it equally. These ownership procedures give no permission to search or dig.
