“Ratchaphatsadu” (ราชพัสดุ) literally translates to “royal supplies” or “state property.” In Thai real estate law, Ratchaphatsadu land means any immovable property owned by the State, with some exceptions. It is the single largest category of government-held land in Thailand. It is often called “treasury land” or “Thanarak land”, after the Treasury Department (กรมธนารักษ์) that administers it. It has nothing to do with the tax forms sometimes confused with it: Por Bor Tor 5 (ภ.บ.ท. 5) was a receipt for the local development tax, repealed from 2020, and Por Dor Sor 3 (ภ.ด.ส. 3) is a form used under the Land and Building Tax Act B.E. 2562. Neither is a title to State land.

Ratchaphatsadu Land in Thailand

1. What Is Ratchaphatsadu Land in Thailand (ที่ราชพัสดุ)?

The governing statute is the Ratchaphatsadu Land Act B.E. 2562 (2019), which by its Section 3 repealed the B.E. 2518 (1975) Act outright. Older sources, and much of the English-language web, still quote the 1975 Act.

Section 6 provides that Ratchaphatsadu land comprises (1) immovable property of every kind that is property of the State, (2) land reserved or set aside for the specific benefit of the State, and (3) land reserved or set aside for official benefit under the law. Because limb (1) reaches immovable property of every kind, buildings and permanent structures on State land are themselves Ratchaphatsadu, not merely fixtures on it.

Section 7 sets out what is not Ratchaphatsadu. It excludes waste and vacant land, and land expropriated, abandoned or otherwise reverted to the State under the land law, except where that land is itself reserved or set aside for the specific benefit of the State or for official benefit.

Key Fact

The Thai Treasury Department manages about 12.5 million rai of Ratchaphatsadu land in Thailand. That is roughly 2 million hectares. Its estimated value, as reported in the Thai press from Treasury Department figures, is over 5 trillion Baht.

In simple terms, Ratchaphatsadu land includes government office buildings. It also includes military sites. It includes state-owned markets. It includes land set aside for agencies. It also includes land the State leases to private parties for commercial or residential use. It does not include public commons land, such as beaches or public roads. It also leaves out land owned by autonomous state enterprises. These include the State Railway of Thailand and the Electricity Generating Authority of Thailand.

For Western readers, Ratchaphatsadu land is similar to “Crown land” in Commonwealth countries or “treasury land”. Examples include Canada, Australia, and the UK.It is also similar to “federal land” in the United States. It is government-owned land that may be leased or used for specific purposes.The public cannot freely buy it.

Ratchaphatsadu land is governed by a layered system of primary legislation, secondary regulations, and ministerial policies. Understanding this framework is essential for anyone seeking to lease or interact with government-owned land in Thailand.

2.1 Ratchaphatsadu Land Act B.E. 2518 (1975)

The original Ratchaphatsadu Land Act was enacted on February 14, B.E. 2518 (1975). It served as the foundational law for more than four decades. This Act has 12 sections. It defined Ratchaphatsadu land. It created the Ratchaphatsadu Land Committee, chaired by the Minister of Finance. It also set basic rules to supervise, maintain, use, and manage state property.

Section 5 of the B.E. 2518 Act vested ownership of all Ratchaphatsadu land in the Ministry of Finance. Section 6 established the Ratchaphatsadu Land Committee with authority to formulate policy and issue Ministerial Regulations. Section 8 said you needed an Act of Parliament to transfer Ratchaphatsadu land. This applied when the land was public land set aside for special state use. Section 9 stated that when the land was no longer needed for its purpose, a Royal Decree had to revoke its reserved status.

Reference: Ratchaphatsadu Land Act B.E. 2518 (1975), Sections 4 to 12; Royal Gazette Vol. 92, Part 54, special issue, page 1, 5 March B.E. 2518.

2.2 Ratchaphatsadu Land Act B.E. 2562 (2019)

The newer Ratchaphatsadu Land Act B.E. 2562 (2019) was published in the Royal Gazette on March 9, 2019. It replaced the 1975 Act to modernize state property management. This updated law set clearer rules for buying, managing, and leasing Ratchaphatsadu land. It also added rules for managing state property outside Thailand. This change reflects Thailand’s growing international government interests.

The B.E. 2562 Act reinforced a rule for government agencies and local administrative organizations. If they want to use Ratchaphatsadu land, they must notify the Treasury Department of their goals. They must also seek formal approval under Ministerial Regulations. It also moved State-property deals out of the Public-Private Partnership (PPP) regime. Under Section 29, exploiting Ratchaphatsadu land with a private party is exempt from the PPP law, except for infrastructure and public-service projects above a value set by ministerial regulation; the 2021 regulation sets that at 5,000 million baht or more (MR B.E. 2564, clause 3). Under Section 28, a deal where the State land is valued at more than 500 million baht needs the Ratchaphatsadu Land Committee’s approval.

Reference: Ratchaphatsadu Land Act B.E. 2562 (2019); Royal Gazette Vol. 136, Part 31 Kor.

2.3 Ministerial Regulations B.E. 2563 (2020) and B.E. 2564 (2021)

For many years the working rules were the Ministerial Regulation on the Administration, Maintenance, Use and Exploitation of Ratchaphatsadu B.E. 2545 (2002), made under the 1975 Act. It no longer applies. Two regulations made under the 2562 Act now cover the ground: the Ministerial Regulation on the Use of Ratchaphatsadu B.E. 2563 (2020), for use by government agencies, and the Ministerial Regulation on the Exploitation of Ratchaphatsadu B.E. 2564 (2021), which governs leases to private parties and whose clause 1 repeals the 2002 regulation. Much of the English-language material still describes the 2002 rules.

The 2021 regulation is the one a private lessee meets. It caps a lease at 30 years unless it is a commercial or industrial lease under the 1999 Act, which needs the Minister’s approval (clause 9). Rent may not be below the rate the Director-General approves, or the Committee’s rate where the land is worth more than 500 million baht (clause 10). The lessee is chosen by auction unless an exception applies (clauses 15 to 17). Deals over 500 million baht go through a separate track: the Committee approves the project and then the contract, a selection committee that includes the Office of the Attorney General runs the tender, and a supervisory committee monitors the contract (clauses 19 to 43).

3. Classification of State Land in Thailand

To understand Ratchaphatsadu land properly, it must be situated within the broader classification of state-owned land in Thailand. The Land Code B.E. 2497 (1954) and related laws recognize several types of government land. Each type has different legal rules and administrative frameworks.

CategoryThai TermDescriptionManaging AuthorityCan Be Leased?
Publicly Used Landที่สาธารณประโยชน์Land commonly used by the public: roads, rivers, beaches, canals, public parksMinistry of Interior / Local GovernmentNo, protected as public domain
Waste Landที่รกร้างว่างเปล่าAbandoned or unused land that has reverted to the StateMinistry of Interior / Land DepartmentMay be allocated for private use under certain programs
Treasury Land (Ratchaphatsadu)ที่ราชพัสดุState-owned land used for government administration, military, commercial leasingTreasury Department / Ministry of FinanceYes, under the Ratchaphatsadu Land Act
State Enterprise Landที่ดินรัฐวิสาหกิจLand owned by state enterprises with juristic person status (e.g., SRT, EGAT)Respective State EnterpriseUnder the enterprise’s own governing law
Government-Reserved Landที่ดินสงวนหวงห้ามLand reserved for specific purposes: natural resources, environmental protectionVarious (Forestry Dept., etc.)Generally no, protected by reservation

Reference: Land Code B.E. 2497 (1954); Chandler MHM, “Doing Business in Thailand,” Chapter 8, Section 2(A).

The key commercial distinction is that Ratchaphatsadu land can be leased to private parties. Unlike public-use or reserved land, it is often leased for business, housing, and farming. This makes it a significant category for businesses, investors, and individuals seeking to utilize state-owned property in Thailand.

4. The Treasury Department (กรมธนารักษ์): Role and Powers

The Treasury Department (กรมธนารักษ์, Krom Thanarak) is a government unit within the Ministry of Finance. It oversees and maintains all Ratchaphatsadu land across Thailand. The Department’s mandate includes surveying state property and keeping a national registry of government-owned immovable property. It also sets assessed land values for tax and fee calculations nationwide. It also manages lease agreements for treasury land.

The Treasury Department’s assessed land values are very important. They set the baseline for transfer fees, taxes, and registration costs in Thailand. This applies to all land transactions. It includes Ratchaphatsadu land and private land transactions. The assessed price announced by the Treasury Department is usually much lower than the property’s market value.

The Department runs provincial offices (สำนักงานธนารักษ์พื้นที่) in every province.These offices act as the local administrative arm. They process lease applications and conduct inspections. They also manage lease relationships. They work with tenants who use state property.

5. The Ratchaphatsadu Land Committee

The Ratchaphatsadu Land Committee (คณะกรรมการที่ราชพัสดุ) is the top policy body for state property in Thailand. It first appeared as Section 6 of the B.E. 2518 Act, but that Act was repealed rather than amended, so the Committee now exists under Chapter 2, Section 9 of the Ratchaphatsadu Land Act B.E. 2562. The 2562 Act also changed who sits on it: it added the Permanent Secretary for Natural Resources and Environment and, for the first time, three expert members appointed by the Minister from people qualified in economics, land, or property development.

The Committee is chaired by the Minister of Finance. It includes the Permanent Secretary of the Ministry of Finance. It also includes the Director-General of the Treasury Department. The Director-General serves as both a member and secretary. Various other senior officials from relevant ministries are also included. Under Section 15 the Committee sets policy on managing Ratchaphatsadu land, sets the rules for the Ratchaphatsadu register and for reporting, and recommends ministerial regulations to the Minister, who issues them. Under Section 28 it must approve any deal with a private party where the land is worth more than 500 million baht, and under Section 22 it decides when a government agency will not hand back land the Treasury Department has recalled.

Practice Point: For high-value or large-scale leases, the lessee must navigate the Treasury Department’s process. The lessee must also secure approval from the Ratchaphatsadu Land Committee. Prospective lessees should factor this committee approval process into their project timelines.

6. How to Lease Ratchaphatsadu Land

Leasing Ratchaphatsadu land is a main way the State earns revenue from its property holdings. The Treasury Department runs a clear process for awarding leases. The terms follow the Ministerial Regulation on the Exploitation of Ratchaphatsadu B.E. 2564 (2021), which replaced the 2002 regulation.

6.1 Eligibility Requirements

Neither the 2562 Act nor the 2021 regulation limits lessees by nationality. Applicants are commonly Thai nationals or Thai-registered juristic persons, and each tender or lease invitation sets its own qualifications. Government agencies, state enterprises, local administrative organizations, educational institutions, and temples may also be granted the right to use state property. Private entities seeking commercial leases must show a valid business purpose. They must also have enough money to develop and maintain the property. This must meet the Treasury Department’s requirements.

The default is an auction (clause 15 of the 2021 regulation). A lease can be granted without one in the cases clause 16 lists, including residential land of up to 100 square wah valued at no more than 50,000 baht per square wah, agricultural land of up to 15 rai valued at no more than 500,000 baht per rai, non-profit public-benefit bodies, civil servants’ welfare schemes, disabled persons’ organisations, and the owner of adjoining land where the State plot is too small to build on.

6.2 Lease Duration and Renewal

Kind of leaseMaximum termSource
Ordinary lease (residential, retail, agricultural)30 yearsCCC s.540; MR B.E. 2564 cl.9
Commercial or industrial lease under the 1999 ActMore than 30 years, up to 50, with the Minister’s approvalMR B.E. 2564 cl.9
Lease in an EEC promotion zone for target industries50 years, renewable for up to 49 moreEEC Act B.E. 2561 s.52
Use by a government agencyNo lease: agreement with the Treasury DepartmentAct B.E. 2562 s.19; MR B.E. 2563

The general maximum lease period is 30 years, under Section 540 of the Thai Civil and Commercial Code. It states that a lease of immovable property cannot exceed 30 years. If the parties agree to a longer term, it will be reduced to 30 years. However, certain special legislation provides exceptions. The Lease of Immovable Property for Commercial and Industrial Purposes Act B.E. 2542 (1999) allows 50-year leases. These leases apply to qualifying commercial and industrial projects. On Ratchaphatsadu land a lease of more than 30 years under that Act also needs the Finance Minister’s approval (clause 9 of the 2021 regulation). The Eastern Special Development Zone Act B.E. 2561 (2018), the EEC Act, allows leases of up to 50 years in its promotion zones, renewable for no more than 49 years (Section 52), and where the EEC Policy Committee resolves to use Ratchaphatsadu land, the Treasury Department’s powers over it pass to the EEC Office (Section 53).

Important: A renewal clause in a Ratchaphatsadu lease does not create a vested right. Renewal is always up to the Treasury Department. The terms, including rental rates, may be renegotiated at renewal. Lessees should not assume automatic renewal.

6.3 Rental Rates and Fees

Rent is not left to the market alone, but market rent is part of the test. Section 27 of the 2562 Act requires any deal with a private party to take into account its purpose, the land’s condition and location, normal market rent, any other return to the State, and the value of buildings that will pass to the Ministry of Finance when the contract ends. Rent may not be below the rate the Director-General approves (clause 10 of the 2021 regulation), and for residential and agricultural leases it is often lower than private-market rent. In addition to monthly or yearly rent, lessees often pay key money (เงินกินเปล่า). They may also pay a building usage fee. This may apply if the lease includes state-owned structures.

The standard registration fee for a Ratchaphatsadu lease is 1% of the total rental value. This amount covers the full lease term. It follows the Land Department’s fee schedule for registered leases in Thailand. Stamp duty of 0.1% of total rent applies (agricultural leases are exempt from stamp duty).

6.4 Step-by-Step Lease Procedure

Obtaining a lease on Ratchaphatsadu land has several steps and often takes months to finish. The exact time depends on the project’s size and value.

Step 1, Identification and Inquiry: The prospective lessee identifies the specific Ratchaphatsadu land plot. They ask about it at the provincial Treasury Department office (สำนักงานธนารักษ์พื้นที่). The office will confirm whether the land is available for leasing and the permitted use categories.

Step 2, Application Submission: The applicant submits a formal lease application. It includes ID documents and business registration for juristic persons. It also includes a proposed use plan and proof of financial capacity. The applicant must also provide any supporting documents required by applicable Ministerial Regulations.

Step 3, Evaluation and Inspection: The Treasury Department conducts a site inspection. It evaluates the application against the Ministerial Regulations. It reviews the proposed rental rate and terms. For large-scale projects, an environmental impact assessment may be required.

Step 4, Committee or Ministerial Approval: Depending on the lease value and type, approval is needed. Where the land is worth more than 500 million baht, the Ratchaphatsadu Land Committee must approve the project and then the negotiated contract (Section 28; clauses 23 and 32 of the 2021 regulation). Below that, the Treasury Department acts under rules the Director-General sets, and a lease over 30 years needs the Finance Minister (clause 9). Cabinet approval is required for transferring Ratchaphatsadu land (Section 31), not for leasing it.

Step 5, Lease Execution and Registration: After approval, the Treasury Department and the lessee sign the lease agreement. If the lease term is more than 3 years, you must register it at the relevant Land Office. This ensures it is enforceable under Section 538 of the Civil and Commercial Code.

Step 6, Ongoing Compliance: The lessee must follow the lease terms. This includes use limits, maintenance duties, and regular reports. The Treasury Department retains the right to inspect the property and may terminate the lease for material breach.

7. Types of Permitted Use of Ratchaphatsadu Land

The Treasury Department permits Ratchaphatsadu land for many uses.These include commercial uses like hotels, department stores, markets, and shophouses.It also allows residential use. Educational and religious uses are allowed, such as temples, schools, and universities. Agricultural use is also permitted.Government agencies may use the land for administrative functions. The permitted uses for any parcel come from the Treasury Department’s zoning and use plan. Lessees must follow the approved use category. Unauthorized changes in use constitute grounds for lease termination.

Several large commercial properties in Bangkok and other provinces sit on Ratchaphatsadu land. These include popular markets, government-owned shop rows, and some hotel projects. The long-term nature of these leases and their lower rental rates make Ratchaphatsadu leases commercially attractive. However, the lessee must accept limits when leasing from the government. The lessee cannot own the land outright.

8. Foreigners and Ratchaphatsadu Land

The intersection of Ratchaphatsadu land and foreign investment is a nuanced area of Thai law. As a general rule, Ratchaphatsadu land leases are awarded to Thai nationals or Thai-registered entities. The Land Code B.E. 2497 (1954) limits foreign land ownership. The Treasury Department’s internal policies are also strict. It follows a similar approach when granting leases on state property.

However, foreigners may indirectly access Ratchaphatsadu land through several recognized structures. A Thai-majority company, with at least 51% Thai shareholding, may apply for a Ratchaphatsadu lease as usual. Foreign investors in BOI projects or in the EEC may also lease state property. They may do so under special lease rules in the related promotional laws. In such cases, the lease is between the Treasury Department and the Thai-registered project entity.

Legal Risk Warning: Using nominee shareholders to bypass Thai ownership rules is illegal. Leasing land is not acquiring it, so a foreign lessee does not breach the Land Code by leasing, but a nominee structure used to run a business the Foreign Business Act B.E. 2542 (1999) reserves to Thais is an offence under that Act. Violations carry criminal penalties including fines and imprisonment. The Treasury Department may also terminate the lease if nominee arrangements are discovered.

8.1 The 99-Year Lease Proposal

A proposal to allow foreigners to hold long-term land leases for up to 99 years has been discussed in Thai policy circles. Under this proposal, Thai landowners who want to lease land to foreigners would first transfer the title deed. They would transfer it to the Treasury Department for oversight. Foreign lessees would then hold a lease for up to 99 years. After that, the land would return to state ownership under the Treasury Department. Restrictions would prevent foreigners from acquiring agricultural land or developing low-income housing under this scheme.

However, as of early 2026, this proposal remains at the discussion stage and has not been enacted into law. The Finance Ministry’s permanent secretary has said that this proposal would need changes to state property law. It would also need changes to related laws. Public consultation would be required under the Constitution. Prospective foreign investors should not rely on this proposal for current planning. They should work within the existing 30-year framework. Special laws may allow a 50-year term.

10. Tax Obligations on Ratchaphatsadu Land

Under the Land and Building Tax Act B.E. 2562 (2019), Ratchaphatsadu land leased to private parties may face annual land and building tax. The tax is based on the value of the land and buildings. It is calculated using rates that vary by use category. These include residential, commercial, agricultural, and vacant. Tax rates range from 0.01% to 0.7% of the assessed value, depending on the use classification and the value tier.

Ratchaphatsadu land used directly by government agencies for governmental purposes is generally exempt from land and building tax. That exemption covers State property used for State or public purposes without profit (Section 8(1)). Once the land is leased to a private party it is being used for profit, and the Act makes the lessee the taxpayer directly: Section 5 defines the taxpayer to include a person who occupies or uses land or buildings that are State property. No clause in the lease is needed for this. The Treasury Department’s assessed land value, which is typically below market value, serves as the tax base.

Lessees should also be aware of income tax implications on buildings or improvements constructed on Ratchaphatsadu land. Upon lease expiration, any structures on the land may revert to the State. This depends on the lease terms. The lessee may or may not receive compensation for these improvements. This is a critical commercial consideration that must be addressed clearly in the lease negotiations.

Reference: Land and Building Tax Act B.E. 2562 (2019); Revenue Code.

11. Transfer, Revocation, and Disposal of Treasury Land

Ratchaphatsadu land cannot be freely transferred or sold in the manner of private land. The rules now sit in Chapter 5 of the B.E. 2562 Act, which carried the 1975 scheme forward with one significant addition. Under Section 30, transferring ownership of Ratchaphatsadu land that is public domain set aside for the specific benefit of the State still requires an Act of Parliament, with a boundary map annexed. Under Section 31, transferring any other Ratchaphatsadu land follows criteria set by ministerial regulation and needs Cabinet approval, which the 1975 Act did not require. Separate routes apply where the transfer is for agricultural land reform, for expropriation, or for a government project the Cabinet has already approved. When land reserved for official use is no longer needed, a Royal Decree revokes the reserved status, again with a boundary map attached.

The B.E. 2562 Act did add one genuinely new mechanism, and it runs the other way. Under Section 32, where Ratchaphatsadu land was acquired by donation and is not put to use within the period the donor set, or within five years of the gift, the donor or their heirs may ask for the land back. Nothing comparable existed in 1975.

11. Supreme Court Decisions on Ratchaphatsadu Land (คำพิพากษาศาลฎีกา)

Thai Supreme Court (San Dika, ศาลฎีกา) decisions interpret the Ratchaphatsadu Land Act and related state property laws. These decisions give essential guidance on how these laws apply in practice. Unlike common law jurisdictions, Thai court decisions do not formally create binding precedent. However, Supreme Court judgments carry strong persuasive weight. Lower courts, lawyers, and the Treasury Department often rely on them. For lessees, investors, and legal advisors, knowing these landmark decisions is key to judging risk. It also helps them handle disputes over treasury land.

11.1 Classification: What Qualifies as State Property (สาธารณสมบัติของแผ่นดิน)

One of the most common issues in Thai land law is whether a parcel is Ratchaphatsadu land.This is state land used for government purposes. Or it may be private land that people can own and sell freely. The Supreme Court has developed a robust body of case law on this classification question.

Supreme Court Decision No. 5200/2566 (2023)

In this landmark case, the Supreme Court addressed the evidentiary weight of a prior final judgment declaring land to be state property. The disputed land was split from a plot that a court had already ruled was public domain property. The property was used for the State’s specific benefit under Section 1304(3) of the Civil and Commercial Code. The defendants argued that the subdivided parcels should not carry the same classification.

The Supreme Court held that a judgment awarding property ownership to one party can bind third parties. This applies unless the third parties prove they have stronger rights. This is based on Section 145, paragraph 2(2) of the Civil Procedure Code. Since the defendants only reinterpreted existing documents, they did not prove stronger rights. The Court upheld the property’s status as state-owned.

Key Principle: When the Supreme Court classifies land as state property (สาธารณสมบัติของแผ่นดิน), that status applies to all subdivided parcels. Third parties claiming rights must affirmatively prove superior title, merely offering alternative interpretations of existing documents is insufficient.

Reference: คำพิพากษาศาลฎีกาที่ 5200/2566; CCC Section 1304(3); CPC Section 145.

Supreme Court Decision No. 3169/2564 (2021)

This decision addressed a dispute. The Ministry of Finance registered its name on a land utilization certificate (NS3, Nor Sor 3). It did so after buying the land from one individual. However, the actual occupant, a different person (“S.”), had possessed and cultivated the land for years. Later, S. sold the land to the plaintiff.

The Supreme Court ruled that the name appearing on the NS3 creates only a presumption of possessory rights under Section 1373 of the CCC. When the possessor (“S.”) had physical control of the land, “S.” had valid possessory rights under Section 1367. “S.” could also transfer those rights. The Ministry of Finance registered its name after buying it from someone without land ownership. This did not override the rights of the person who actually possessed the land.

Key Principle: Listing the Ministry of Finance on a land certificate creates a presumption, not final proof. Actual physical possession (การครอบครอง) prevails over paper registration. A person who never took physical possession cannot validly sell land to the government. The government’s later registration does not fix this defect.

One caveat before you rely on this as a Ratchaphatsadu case. The buyer here was the Agricultural Land Reform Office (ส.ป.ก.), and Section 36 bis of the Agricultural Land Reform Act B.E. 2518 provides that land it acquires is not to be treated as Ratchaphatsadu land. The possession rule the case lays down is general and applies either way, but the land itself sat outside the Ratchaphatsadu regime.

Reference: คำพิพากษาศาลฎีกาที่ 3169/2564; CCC Sections 1367, 1373; Agricultural Land Reform Act B.E. 2518, Section 36 bis.

What the Act itself defines as Ratchaphatsadu land

The definition does not come from case law at all. It is set out in Section 6 of the Ratchaphatsadu Land Act B.E. 2562 (2019), which by Section 3 repealed the 1975 Act that older sources still cite. Ratchaphatsadu land is (1) immovable property of the State of every kind, which is why buildings and other structures on state land are included, (2) land reserved or set aside for the specific benefit of the State, and (3) land reserved or set aside for official use under any law.

Section 7 matters just as much, because it lists what is not Ratchaphatsadu land, including vacant and abandoned land under the Land Code, public property for the common use of the people, and the immovable property of state enterprises that are juristic persons and of local administrative organisations. If your plot falls under Section 7, the Treasury Department is not your counterparty.

Reference: Ratchaphatsadu Land Act B.E. 2562, Sections 3, 6 and 7.

11.2 Encroachment and Eviction from Treasury Land

Disputes involving unauthorized occupants on Ratchaphatsadu land are among the most common state property cases in the Thai courts. The Supreme Court has upheld the government’s right to evict encroachers. It has also recognized the rights of occupants with valid possessory claims.

Supreme Court Decision No. 2103/2565 (2022)

The plaintiff lived on a plot of land in Kanchanaburi Province, paid local taxes, and installed concrete boundary posts. The provincial Treasury Department office (สำนักงานธนารักษ์พื้นที่กาญจนบุรี) later surveyed the land. It found the land was Ratchaphatsadu property. It also had the features of a public right-of-way. When third parties entered the property to lay drainage pipes, the plaintiff sued for trespass and criminal damage. The Supreme Court held that the land was ultimately state property. Still, the plaintiff’s ongoing physical occupation gave him standing. He could file trespass and property damage claims. The plaintiff’s possessory rights, inherited from his predecessor in title, were enough to maintain the criminal action. This was true even if the state owned the property.

Key Principle: A person physically occupying Ratchaphatsadu land, even without formal authorization, retains possessory rights that the courts will protect against third-party interference. However, this does not create ownership rights. The occupant is still subject to the Treasury Department’s authority to take back the land.

Reference: คำพิพากษาศาลฎีกาที่ 2103/2565; Criminal Code Sections 362, 365, 358.

Supreme Court Decision No. 8649/2560 (2017)

The defendant pleaded guilty to occupying Ratchaphatsadu land, charged under the Land Code and the Forestry Act together, and the prosecution also asked for eviction of the defendant, workers, contractors, agents and dependents. The trial court treated the conduct as a single act offending several laws and sentenced under the heaviest provision, which is how Section 90 of the Criminal Code works. It is not a case of cumulative penalties under each statute.

What the Supreme Court actually decided is narrower and worth knowing if you are charged. It held that Section 74 bis of the Forestry Act is not an offence-creating provision at all. It only empowers the court to forfeit tools, animals, vehicles and machinery used in committing certain offences, so convicting the defendant under it was wrong. And because the prosecution had not pleaded that anything was seized, there was nothing for the court to forfeit even though the request appeared at the end of the charge.

11.3 Lease Disputes and Sub-Lease Rights

Supreme Court Decision No. 8901/2563 (2020)

This important decision addressed the legal position of sub-lessees on Ratchaphatsadu land. The defendant, the body holding the Ratchaphatsadu area and acting as head lessor, signed a lease with Plaintiff No. 1. Plaintiff No. 1 then subleased the property to Plaintiff No. 2. Plaintiff No. 2 then subleased the property to Plaintiff No. 3.When a dispute arose, Plaintiff No. 3 tried to claim rights directly against the Treasury Department.

The Supreme Court ruled under Section 545 of the CCC.A sub-lessee is directly responsible to the original lessor. This is a one-way obligation. It is a statutory exception to the general rule. Contracts usually bind only the parties who signed them. The Court held that this exception cannot be read in reverse. It does not allow a sub-lessee to bring claims against the original lessor. Because no law gives the sub-lessee rights against the original lessor, Plaintiff No. 3 lacked standing and its claim was dismissed as well.

Key Principle (Critical for Lessees): Section 545 runs one way only. A sub-lessee is directly liable to the head lessor, but acquires no rights against it, and the exception cannot be read in reverse. On Ratchaphatsadu land the head lessor is the government body holding the area, which is not necessarily the Treasury Department itself, so identify it from the head lease before assuming who your counterparty is. Either way the sub-lessee must enforce its rights against its own immediate lessor: if the head lease ends, the sub-lessee cannot challenge that decision and can only claim damages from the head lessee.

Reference: คำพิพากษาศาลฎีกาที่ 8901/2563; CCC Section 545.

Supreme Court Decision No. 13387/2555 (2012)

Two landowners sued four defendants over whether land occupied by an agricultural college was Ratchaphatsadu property. Two of those defendants were the college and the Singburi provincial Treasury office (ธนารักษ์พื้นที่สิงห์บุรี).

The Supreme Court threw those two out of the case, and this is the practical point for anyone planning to sue. It read the body of the complaint rather than the names in the caption, found that both had been sued as government sub-units rather than as the individuals heading them, and held that a sub-unit which is not a juristic person cannot be sued at all. The plaintiffs had no power to sue them. A provincial Treasury office is a branch of the Treasury Department, not a legal person in its own right.

Practical effect: name the Treasury Department itself, or the ministry the agency sits under. Naming the provincial office will cost you that defendant, and the Court will look at how you pleaded the claim, not at the caption.

11.4 Retrial Finality: When the Court of Appeal Has the Last Word

Supreme Court Decision No. 5161/2566 (2023)

This is a procedural ruling, not a land case, and we include it only for the appeal rule it settles. The underlying prosecution had nothing to do with title deeds: it concerned charges under Section 112 of the Criminal Code, alongside a separate fraud case about a construction contract.

The rule is the useful part, and it applies to any retried criminal case. Once a trial court has reopened a case under the Criminal Case Retrial Act B.E. 2526, quashed the old judgment and entered a fresh one under Section 13(1), the right of appeal is governed by Section 15. If that fresh judgment goes to the Court of Appeal, the Court of Appeal decision is final and there is no further appeal to the Supreme Court. A defendant who files one anyway will find it was never properly admitted.

11.5 Jurisdictional Issues: Civil Courts vs. Administrative Courts

Supreme Court Decision No. 4818/2562 (2019)

This significant procedural decision clarified the boundary between civil court and administrative court jurisdiction in Ratchaphatsadu land disputes. The plaintiffs filed a civil case challenging the legality of a Royal Decree affecting state property. The Jurisdictional Dispute Resolution Committee ruled that the case challenged the legality of a Royal Decree.

The Decree was issued by, or approved by, the Cabinet. The Committee said this issue falls under the Supreme Administrative Court’s exclusive jurisdiction. The Supreme Court confirmed that the Committee’s decision is final.This is based on Sections 10 and 11 of the Jurisdictional Dispute Resolution Act B.E. 2542 (1999). The civil court must either transfer the case or dismiss it so that the parties can re-file in the Administrative Court.

Key Principle: Disputes that challenge Royal Decrees about Ratchaphatsadu land must go to the Supreme Administrative Court. They must not be filed in civil courts. Filing in the wrong court will result in dismissal or transfer, costing the litigant significant time and expense. Legal counsel should carefully assess jurisdictional questions before commencing proceedings.

11.6 Forest Reserve to Ratchaphatsadu Conversion: What a Defamation Case Does and Does Not Settle

Supreme Court Decision No. 321/2568 (2025)

Read this one carefully, because it is a criminal defamation case and not a ruling on land law. It is included here only because conversion of national forest reserve land into Ratchaphatsadu land was the subject of the accusation. In this case from Phetchabun Province, the defendant put up large vinyl banners. The banners were placed along the Phitsanulok-Lom Sak highway.They accused the provincial governor of seeking Cabinet approval. The approval was to convert national forest reserves into Ratchaphatsadu land.The defendant claimed this would benefit capitalists and politicians. They were allegedly linked to illegal forest encroachment in the Khao Kho area. The banners used language like, “Use Khao Kho as a model to help politicians who take forest land keep it legally.”

The Supreme Court upheld the criminal defamation conviction. The Court found the defendant’s accusations were untrue. The governor had only applied existing government policy. This was one way to address illegal forest encroachment. The Court also ruled that putting up public banners was not good-faith criticism. This was under Section 329 of the Criminal Code. The Court affirmed damages of 500,000 Baht for reputational harm.

Significance for Ratchaphatsadu law, stated precisely. The Court made no ruling on whether converting national forest reserve land (ป่าสงวนแห่งชาติ) into Ratchaphatsadu land is lawful, and this case is not authority that it is. What the Court found, in the course of holding the accusation untrue, is narrower: the governor was an official with a duty to protect the forest and had “merely acted in accordance with the government’s policy at the time, which was only one approach to solving the problem of encroachment on national forest reserves”. That establishes that such a conversion route was being pursued as government policy in the relevant period. It does not establish that the route is legally valid, and nothing in the judgment addresses the question. Treat the conversion mechanism as a policy matter to be checked against the Treasury Department and the governing Act, not as something settled by this decision.

Practical Lessons for Lessees and Investors

Supreme Court rulings on Ratchaphatsadu land offer key practical lessons for anyone leasing or dealing in state property:

1. Conduct thorough due diligence on land classification. The 5200/2566 decision shows that state property classification, once established, is extremely difficult to overturn. Before entering any land transaction with possible government ties, check its classification history. Use records from the Treasury Department and the Land Department.

2. Verify actual possession, not just paper titles. The 3169/2564 decision shows that Thai courts focus on who uses and occupies the land. They do not rely only on the name on the certificate. This is critical when purchasing land from entities claiming government-derived title.

3. Structure sub-lease arrangements carefully. The 8901/2563 decision makes clear that sub-lessees have no direct recourse against the Treasury Department. Any sub-lease on Ratchaphatsadu land must include contract protections from the head lessee. This is because if the head lease ends, the sub-lessee can only claim against the head lessee. The sub-lessee cannot claim against the government.

4. File in the correct court. The 4818/2562 decision confirms this rule.You must file challenges to government decisions in the Administrative Court.This includes Royal Decrees and Ministerial Regulations.This applies when decisions affect Ratchaphatsadu land.Do not file these cases in the civil court. Filing in the wrong forum wastes time and resources.

5. Unauthorized occupation carries criminal liability, but check the sections charged. Encroachment on state land is a criminal matter, not merely a civil dispute. Section 45 of the 2562 Act punishes occupying Ratchaphatsadu land without right, disturbing its use, or damaging it with up to five years’ imprisonment, a fine of up to 100,000 baht, or both; the court can order the offender, workers, contractors, agents and dependants off the land, and tools and machinery used are forfeited. The 8649/2560 decision is a caution on the other side: the courts below convicted under a Forest Act provision that creates no offence, and the Supreme Court quashed that part. Read every section in the charge before advising on exposure.

12. Practical Considerations and Risks

Leasing Ratchaphatsadu land offers commercial benefits, mainly lower rent and access to prime government-owned locations. However, it also brings unique risks that private land deals do not.

No ownership interest: The lessee acquires only a leasehold right, not an ownership interest. The land cannot be used as collateral for a mortgage. Still, the leasehold interest may have some value in financing talks. This limits the lessee’s ability to leverage the property for external financing.

Government discretion on renewal: Lease renewal is not a right but a privilege. The Treasury Department may decline to renew, change the terms, or reallocate the land for a different purpose. Lessees who invest a lot in improvements should negotiate clear renewal terms and compensation in the original lease.

Restricted transferability: As with a private lease (section 544 of the Civil and Commercial Code), a Ratchaphatsadu lease cannot be assigned or sublet without the Treasury Department’s prior written consent. This limits the lessee’s ability to exit the arrangement or bring in partners.

Reversion of improvements: Unless the lease explicitly provides otherwise, structures and improvements made by the lessee on Ratchaphatsadu land may revert to the State upon lease expiration. This is a major financial risk, particularly for lessees who invest heavily in building development on state property.

Political and policy risk: Government policy on Ratchaphatsadu land may shift with changes in administration. New policies regarding rental rates, permitted uses, or lease durations can affect existing lessees, particularly upon renewal.

Last reviewed: 27 September 2026. Read in Thai for this review: the Ratchaphatsadu Land Act B.E. 2562 (all sections) and the 1975 Act it repealed; the Ministerial Regulation on the Exploitation of Ratchaphatsadu B.E. 2564; the Land and Building Tax Act B.E. 2562, sections 5 and 8; the EEC Act B.E. 2561, sections 52 and 53. The Revenue Code stamp-duty provisions (sections 107 and 121 and the Schedule) were read in the Revenue Department’s English text. The Supreme Court decisions were checked against the judgments in an earlier review and were not re-read for this one. The land-area and value figures come from press reports of Treasury Department data, and the 99-year lease proposal was not re-checked.

13. Frequently Asked Questions

What is the difference between “tanarak” and “ratchaphatsadu”?

“Tanarak” (ธนารักษ์) refers to the Treasury Department itself, the government body that manages state property. “Ratchaphatsadu” (ราชพัสดุ) refers to the state property (land and buildings) that the Treasury Department manages. In everyday Thai, people often say “ที่ดินธนารักษ์” (tanarak land). They mean Ratchaphatsadu land. They use the managing agency’s name instead of the legal land type.

Can I build a house on Ratchaphatsadu land?

Yes, if the lease permits residential construction. Many Thais build homes on leased Ratchaphatsadu land, especially in areas set aside for housing. However, the lessee should carefully review the lease terms regarding ownership of the structure upon lease expiration.

Is Ratchaphatsadu land cheaper than private land?

Yes, rental rates for Ratchaphatsadu land are usually lower than similar private-market rates. The Act requires regard to normal market rent among other factors (Section 27), with a floor the Director-General approves. However, the trade-off is the lack of ownership rights and the restrictions inherent in leasing from the government.

Can a Ratchaphatsadu lease be inherited?

A standard lease under the Civil and Commercial Code is a personal right and ends when the lessee dies. For Ratchaphatsadu leases, clause 11 of the 2021 Ministerial Regulation lets the Treasury Department allow one of the heirs to take over the lease for the remaining term, on the Director-General’s rules. It is a discretion, not an automatic right.

What happens if I default on the lease?

The Treasury Department may terminate the lease for non-payment of rent or breach of lease conditions. The lessee may need to leave the land. They may also lose any structures or improvements without compensation, based on the lease terms.

Ratchaphatsadu land represents a substantial and strategically important category of real property in Thailand. With over 12.5 million rai managed by the Treasury Department, it supports government operations nationwide. It also supports businesses, homes, and public institutions across the country. The legal framework is the Ratchaphatsadu Land Act B.E. 2562 (2019), which by its Section 3 repealed the Ratchaphatsadu Land Act B.E. 2518 (1975) outright rather than amending it. It is supported by the Ministerial Regulations B.E. 2563 (2020) and B.E. 2564 (2021), which replaced the 2002 regulation. It provides a clear system for administering, leasing, and managing state property.

For Thai nationals and Thai-registered businesses, leasing Ratchaphatsadu land can be a strong option. It offers lower rental costs, access to well-located government property, and long-term stability. For foreign investors, the opportunities are more limited but not fully closed. They are available through BOI-promoted projects, EEC zone developments, and well-structured Thai-majority entities.

As with all aspects of Thai property law, proper legal due diligence and expert guidance are essential. The Ratchaphatsadu Land Act, the Land Code, the Civil and Commercial Code, and other special laws create complex rules. These rules reward careful planning and punish assumptions.
