Metal Detecting Laws in Taiwan

A general rule allowing hobby metal detecting in Taiwan could not be confirmed, including searches for modern lost items. The confirmed rules answer narrower questions: archaeological excavation needs specialist approval, some protected zones restrict digging or entry, and different reporting and ownership rules apply to lost property and heritage finds. Landowner agreement alone does not replace archaeological approval.

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.

Ordinary detecting and private land

Permission for ordinary detecting could not be confirmed nationally or for beaches, state forests, national parks, protected monuments, or private land. The 文化資產保存法 (Cultural Heritage Preservation Act) regulates archaeological-site excavation and foreign archaeological surveys; those rules do not establish permission to search for modern lost items.

On private land, obtain the owner’s agreement: Article 765 of the 民法 (Civil Code) gives owners the right to use their property and exclude interference, subject to legal limits. That agreement does not replace the archaeological approvals in Articles 51–52 of the heritage Act. A specific hobby-detecting rule for private land remains unconfirmed.

Archaeological excavation and discoveries

Archaeological-site excavation requires an application by qualified scholars, experts, or academic or professional institutions, committee review, and heritage-authority approval under Article 51. The 考古遺址發掘資格條件審查辦法 (Regulations for Reviewing Archaeological Excavation Qualifications and Conditions) include preliminary trial digging and exploration, and require archaeological qualifications, suitable institutional resources, an excavation plan, and written consent from the landowner, user, or manager (Articles 2 and 4–6). These are archaeological requirements, not a confirmed rule for every ordinary target-recovery hole. Suspected and listed archaeological sites are also covered (heritage Act Article 59; regulations Article 14).

Foreigners may conduct archaeological surveys or excavations only through collaboration with a domestic academic or professional institution and permission from the Ministry of Culture (heritage Act Article 52). For archaeological excavation collaborations involving foreigners, the project director must be a Republic of China national (regulations Articles 2 and 12). Where there is an urgent need to rescue an archaeological site, including an emergency involving a natural disaster, public safety, or another accident, regulations Article 9 allows the excavator to begin excavation with the competent authority’s agreement and submit a supplementary application within one month after excavation begins.

If you discover a suspected archaeological site, immediately notify the competent heritage authority of the special municipality or county/city where it is located. An ownerless object with antiquity value also requires immediate notification to that local authority and protective measures. If construction or other development reveals a suspected archaeological site or an object with antiquity value, whether or not the object is ownerless, immediately stop that work and notify the local authority; development at a suspected site cannot resume before the review procedure is complete (Articles 4, 57, 76, and 77).

Objects excavated from archaeological sites must be inventoried and delivered to the custodial institution designated by the authority; the same requirement extends to suspected and listed sites (Articles 53 and 59). This establishes custody, not a blanket rule that every old object is state-owned. Civil Code Article 809 leaves ownership of buried objects with academic, artistic, archaeological, or historical value to special legislation.

Parks, reserves, and forests: the zone matters

An ordinary detecting rule covering every national park or state forest could not be confirmed. The 國家公園法 (National Park Law) regulates specified activities, including mineral or soil and stone exploration and extraction, land cultivation or changed use, and artificial terrain changes in historic preservation zones (Articles 14–16). Entry to a national park’s ecological protection zone requires park-administration permission (Article 19). These provisions do not establish one detector rule for every park zone.

In 自然保留區 (nature reserves) designated under the heritage Act, Article 86 prohibits changing or destroying the original natural state. Recovering a target in a way that changes that state is therefore prohibited; the provision does not name detector sweeping itself. Entry separately requires authority permission unless another law provides otherwise. Entry permission is not an exemption from the natural-state restriction.

自然保護區 (nature protection areas) under the 自然保護區設置管理辦法 (Regulations for Establishment and Management of Nature Protection Areas) are a different category. In their 永續利用區 (sustainable-use zones), digging up buried objects requires permission from the competent authority, applied for through the managing agency or management unit (Article 11). This requirement concerns recovery, not an express rule about detector sweeping. Core and buffer zones have restricted entry: Article 10 provides permission where necessary for academic research, controlling or preventing infectious disease, or maintaining the original natural environment; it is not a hobby-access permit.

Within forest recreation areas, 森林生態保育區 (forest ecological conservation zones) prohibit changing or destroying the original natural state, so target recovery that does so is prohibited. Visitors also need central-authority permission to enter, under Article 12 of the 森林遊樂區設置管理辦法 (Regulations for Establishment and Management of Forest Recreation Areas). This is a zone-specific rule; detector sweeping itself is not named.

The 森林法 (Forestry Act) requires authority agreement after a joint site inspection for mineral exploration or extraction, soil or stone taking, and specified works (Article 9). Protection forests separately restrict taking or digging soil, stone, turf, and roots without approval or consent (Article 30). These provisions do not confirm a general state-forest detecting rule or make every recovery hole a mineral-exploration project.

Ordinary lost property and buried objects

For ordinary lost property, Civil Code Articles 803–804 require prompt notification of the loser, owner, or another entitled recipient, or a report to the police or autonomous authority. When reporting, deposit the object too. For finds in an agency, school, organization, or other public place, you may instead report and deposit it with that place’s managing body or responsible person. Report recipients must promptly advertise for the owner. If direct notification or a public-place announcement brings no claim within a reasonable period, the finder or person advertising must deposit the object with the police or autonomous authority.

Under Article 807, an ordinary lost object becomes the finder’s property only after more than six months from notification or the last public announcement without a claim by someone entitled to it. The police or autonomous authority then notifies the finder to collect the object or sale proceeds, or publishes an announcement if notification is impossible. Failure to collect within three months of that notice or announcement transfers the object or proceeds to the local autonomous entity where it was kept.

For objects worth NT$500 or less, Article 807-1 requires prompt notification of an entitled person and also allows the public-place procedure. If no entitled person claims the object, the ownership waiting period is more than 15 days after notification or announcement, or more than one month from finding if that notification/public-place procedure cannot be followed. The seven-day provision in Article 805-1 concerns eligibility for a finder’s reward; it does not replace the duty to act promptly.

Ordinary buried objects follow a different rule. Under Article 808, a finder who discovers and takes possession of a buried object acquires ownership; when it is found in someone else’s movable or immovable property, the finder and that property’s owner each acquire half. Article 809 reserves buried objects with academic, artistic, archaeological, or historical value to special legislation. Article 802 separately allows ownership of an ownerless movable taken with intent to own it unless another law provides otherwise; lost property still has its own procedure.

Beaches and underwater heritage

Ordinary beach and foreshore detecting for modern lost items remains unconfirmed. The 水下文化資產保存法 (Underwater Cultural Heritage Preservation Act) covers qualifying heritage wholly or partly underwater, periodically or continuously, with the historical, cultural, archaeological, artistic, or scientific value described in Article 3. It defines activities targeting that heritage as field investigation, research, excavation, and other potentially disturbing or damaging acts undertaken for preservation, protection, management, research, or education.

Those targeted activities require a specialist activity plan and prior Ministry of Culture approval; foreign applicants must collaborate with a domestic academic or professional institution (Articles 2 and 22). Bringing heritage out of the water is separately limited to the preservation, research, or other needs specified or approved under Article 34, and requires a conservation plan under Article 35. These requirements do not establish permission for modern lost-item searches.

Anyone who discovers suspected underwater heritage must stop activities affecting it, preserve the scene, and immediately notify the Ministry of Culture. An activity need not stop where necessary to avoid imminent danger or for a major public interest, but immediate notification still applies. If the suspected heritage has already been brought out of the water, immediately deliver it to the Ministry (Articles 2 and 13).

Underwater heritage is excluded from the ordinary Civil Code rules for ownerless, lost, buried, drifting, and sunken property and relevant salvage rules. Heritage discovered within the Act’s internal-waters and territorial-sea scope is state-owned, except foreign state vessels or aircraft whose ownership has been asserted; that exception gives no title to the finder. Authorized excavation finds must be inventoried and reported within the authority’s deadline and preserved as directed (Articles 14–15 and 36). Civil Code Article 810 otherwise applies lost-property rules to drifting or sunken objects and other objects removed from someone’s possession by natural forces.
