For many foreign investors, buying property in Thailand is often the easy part.
The real challenges usually appear years later.

Many investors focus on the property itself — the villa, condominium, land, or development project. However, few take the time to carefully consider the legal structure behind the investment.

Unfortunately, some of the most serious property disputes in Thailand do not arise because of the property.


They arise because of the ownership structure chosen at the beginning
Questions such as:

• Who legally controls the land?
• What happens if relationships change?
• Can the investment be transferred or inherited?
• Will the structure still work 10, 20, or 30 years from now?
• What happens if government policies become stricter?

These are issues that many investors only begin to consider after problems arise.

Common concerns include nominee investigations, ownership disputes, inheritance complications, transfer restrictions, tax exposure, and long-term dependence on third parties.

---

THE PROPERTY MAY BE VALUABLE.

BUT THE STRUCTURE HOLDING IT MATTERS EVEN MORE.

A well-designed legal structure can provide greater certainty, flexibility, inheritance planning, and long-term investment security.

That is one of the reasons why many foreign investors explore alternative legal structures such as SAP-ING-SITH (Right Over Leasehold Asset) when investing in Thailand.

Not Sure Whether Your Current Structure Is Safe?

For many foreign investors, one of the biggest concerns when investing in Thailand is not simply whether they can purchase the property — but whether the ownership structure itself will remain legally secure in the future.

Over the years, many investors relied upon leasehold arrangements, nominee structures or holding companies without fully understanding the long-term legal and tax implications involved. In practice, some structures later created problems involving inheritance rights, transferability, retroactive tax exposure, ownership disputes, forced asset sales or regulatory scrutiny.

Sap-Ing-Sith (Rights Over Leasehold Asset), often referred to in the market as the “Blue Garuda Deed,” was introduced under Thai law, RIGHTS OVER LEASEHOLD ASSET ACT B.E. 2562 announced on April 2019, as a legally recognized and registrable “PROPERTY RIGHT” intended to support long-term foreign real estate investment while reducing reliance on nominee arrangements and legally questionable ownership structures.

Upon establishing the RIGHT OVER (LEASEHOLD) ASSET, “the certificate of rights over leasehold asset (Blue Garuda Deed) will be issued. Its function is almost equal to the title deed (RED Garuda Deed) or strata title (the document of condo ownership—”Aor”Chor 2” in Thai) as the case may be. The Sap-Ing-Sith holder has right, duty, and liability in the immovable property which it has been established as if he/she is the owner of immovable property, except right to track and get immovable property back from a person who has no right to hold onto and right to obstruct another person not to interfere illegally with such immovable property. (Section 11)

Although it is not direct ownership of land, Sap-Ing-Sith provides foreigners with a formally registered right over immovable property under a dedicated statutory framework together with significantly greater legal structure, transferability and long-term investment certainty than traditional long-term lease registration.

• Separate government-issued certificate (Blue Garuda Deed) for foreign investors
• Rights and practical usage capability similar to title ownership in many aspects
• Ability to apply for construction permits and deal directly with government authorities
• Greater independence from the underlying land owner during the registration period
• Transferable and capable of being mortgaged or used as collateral (Section 12)
• Inheritable and suitable for long-term succession planning
• Greater legal certainty and structural clarity than traditional long-term lease arrangements
  

For foreign investors seeking to secure villas, retirement residences and long-term property investments in Thailand legally, professionally and tax-efficiently, Sap-Ing-Sith has become one of the most important legal alternatives available under Thai law today.

Sap-Ing-Sith (Rights Over Leasehold Asset) is a unique legal concept created specifically under Thai law and exists only in Thailand. It represents one of the few occasions in which Thai legislation was intentionally designed to support long-term foreign investment in Thai real estate through a legally recognized and registrable property right.

The legislation emerged from Thailand’s broader policy objective of promoting foreign investment in the real estate sector. Over the years, lawmakers and policymakers recognized that many legal rights previously used by foreign investors — including traditional leasehold arrangements, usufruct rights and various holding structures — were not originally designed for long-term foreign property ownership or residential investment purposes

As a result, Sap-Ing-Sith was introduced as a dedicated legal framework intended to allow foreigners to hold legally recognized “rights” over Thai real estate in a more transparent and regulated manner, while also reducing reliance on nominee arrangements and legally questionable ownership structures.

Originally, early legislative discussions contemplated granting Sap-Ing-Sith rights for a significantly longer duration than the conventional 30-year leasehold framework, potentially extending to approximately 60 years in order to better support long-term foreign investment. However, due to legislative and policy considerations, the final enacted structure ultimately adopted a registration period more closely aligned with the traditional 30-year framework. (Section 4)

Nevertheless, the underlying legislative structure and policy direction of Sap-Ing-Sith were originally designed with the possibility of substantially longer durations in mind — potentially extending to 60 or even 90 years if supported by future government policy and legislative reform.

From a legislative perspective, expanding the duration of Sap-Ing-Sith rights in the future may also be more practical than attempting to amend the broader leasehold framework under Section 540 of the Civil and Commercial Code together with related Land Department regulations and administrative provisions governing traditional leasehold registration.

For this reason, many legal practitioners and real estate professionals continue to view Sap-Ing-Sith as a legal framework with significant long-term policy potential for future foreign real estate investment structures in Thailand.

Because Sap-Ing-Sith remains relatively new within the Thai legal system, registration procedures and administrative practices may still vary among Land Offices in different jurisdictions throughout Thailand. For this reason, professional legal coordination and practical experience remain important when structuring and registering Sap-Ing-Sith rights.

Although the legislation itself is still relatively new and there are currently very few Supreme Court precedents directly interpreting Sap-Ing-Sith structures, it has nevertheless become one of the most significant legal mechanisms specifically intended to support legally recognized foreign property rights in Thailand.

---

Under current Thai law, Sap-Ing-Sith may only be established over certain categories of immovable property specifically permitted by law.
The most common eligible property types include:

1. land that has title deed / Chanote Land Title (Nor Sor 4 Jor)
2. land with structure in land that has title deed (Nor Sor 4 Jor)
3. strata title condominium unit under the law on condominium (section 3)
   

In practice, Sap-Ing-Sith structures are particularly common in relation to luxury villas, private residences, retirement properties and long-term foreign investment properties throughout Thailand.

---

One important issue frequently misunderstood by foreign investors is the distinction between ownership of “land” and ownership of “buildings” under Thai law.

Although foreigners are generally prohibited from directly owning land in Thailand, Thai law does not prohibit foreigners from legally owning buildings or structures constructed upon land.

In the context of Sap-Ing-Sith, the holder of the registered right may, subject to applicable laws and approvals, apply for construction permits in their own name and may also legally own the buildings or structures subsequently constructed on the land.

In practice, this is an extremely important feature for foreign investors seeking to develop private villas, retirement residences, vacation homes or long-term residential investment properties in Thailand.

For this reason, proper structuring of both the land rights and the ownership of buildings and improvements remains a critical component of sophisticated property planning involving Sap-Ing-Sith structures.

---

1) Upon establishing SAP-ING-SITH, “the certificate of rights over leasehold asset” will be issued to the foreigner, holder. Its function is almost equal to the title deed or strata title (the document of condo ownership—”Aor”Chor 2” in Thai).

2) SAP-ING-SITH is Transferable: Unlike a lease agreement, which is personal to the lessee, a Right Over Leasehold Asset can be transferred to another person.

3) Right Over Leasehold Asset as Collateral: SAP-ING-SITH can be used as collateral for loans or other financial obligations. This provides the holder with greater access to financing options.

4) Right Over Leasehold Asset SAP-ING-SITH as Inheritance: Upon the death of the holder, it can be passed on as part of their inheritance. This ensures the continued enjoyment of the property rights by their successors.

5) A holder of SAP-ING-SITH has right to utilize immovable property. (Section 10) There is no need for the permission of the property owner in official business, ex. applying the building permit, asking for electricity & water meter, doing the plantation, etc.

6) When establishment of SAP-ING-SITH in any immovable property, owner of immovable property cannot establish any proprietary interest in such immovable property except receiving written consent from the holder. (Section 9)

Besides Leasehold and SAP-ING-SITH, two other important legal structures commonly used in Thailand are:

• The Right of Superficies (สิทธิเหนือพื้นดิน)
  Civil and Commercial Code: Sections 1410–1416 CCC
• The Right of Usufruct (สิทธิเก็บกิน)
  Civil and Commercial Code: Sections 1417–1428 CCC
  

Unlike SAP-ING-SITH, these rights are primarily designed for long-term residential security and family protection, not investment flexibility.

Key Advantage: Lifetime Security

Both Superficies and Usufruct may be registered for:

This means the rights can remain valid for life unless:

• The rights holder passes away, or
• The rights are voluntarily terminated
  

In many cases, this offers stronger long-term residential security than leasehold and even SAP-ING-SITH

Key Limitation: Personal Rights Only

However, these rights are generally personal rights.

This makes them less suitable for investment or resale.

Best Used For

Superficies and Usufruct are commonly used for:

Important Legal Hint (Updated 2026)

Due to stricter anti-nominee enforcement, Land Offices now increasingly scrutinize Superficies and Usufruct registrations involving foreigners.

In many areas, officials may require proof of genuine relationship between the foreigner and the Thai landowner, such as: Spouse, Parent / Child, Family member

In practice, these structures remain strong for long-term living — but are generally not ideal for investment purposes.


Quick Comparison

• SAP-ING-SITH → Better for investment, transferability, and inheritance planning

• Superficies / Usufruct → Better for lifetime occupancy and family protection
  
  

---

While Sap-Ing-Sith provides a sophisticated legal framework for long-term foreign property investment in Thailand, proper tax planning and ownership structuring remain extremely important.

In practice, many investors focus only on whether the structure can be successfully registered at the Land Office, without fully considering future tax exposure, long-term obligations or Revenue Department scrutiny.

Over the years, we have encountered increasing numbers of cases involving holding companies, developer structures and property arrangements that were successfully registered initially, but later became subject to substantial retroactive tax assessments because the structures focused primarily on registration while failing to properly address personal income tax, corporate tax and long-term compliance issues.

In some situations, additional liabilities and restructuring costs were later passed on to foreign investors, resulting in unexpected expenses equivalent to approximately 10–20% or more of the property value.

For this reason, sophisticated investors increasingly focus not only on whether a structure can be registered today, but whether the structure has been professionally designed to remain:

• legally sustainable,
• tax-efficient,
• commercially supportable,
• and defensible under future regulatory scrutiny.

---

Who Should Hold the Title Deed?

One of the most important practical questions surrounding Sap-Ing-Sith structures is not only how the right itself should be registered — but who should hold the underlying title deed ownership.

The answer depends heavily on the investment objective, long-term relationship structure, tax planning considerations and the overall legal sustainability of the arrangement.

In practice, several different structures may be used depending on the circumstances involved.

1) Existing Land Owner / Property Owner

In some cases, the original owner or developer continues holding the underlying ownership while establishing Sap-Ing-Sith rights for the foreign investor.

However, long-term contractual obligations should be reviewed carefully, particularly regarding land and building tax, personal income tax exposure, maintenance obligations, renewal obligations, inheritance responsibilities and future re-establishment of rights after expiry.

Improper tax planning or unclear contractual allocation of responsibilities may later create substantial liabilities for both parties.

2) Legitimate Holding Company

Some investors may choose to use a properly structured “Legitimate Holding Company” established under Thai law & 100% Thai Shareholder to hold the underlying ownership and establish Sap-Ing-Sith rights.

Likewise, certain developers may already provide holding structures as part of their investment model. However, Investors should carefully review whether the company has real operational income, shareholders possess genuine financial capability, source of investment funds can be demonstrated and the structure reflects genuine commercial substance.

Long-term tax planning also remains extremely important, particularly regarding corporate income tax, land and building tax, annual service fees, transfer obligations and potential retroactive tax exposure.

3) Thai Spouse

In some situations, investors may choose to structure ownership together with a lawful Thai spouse.

While this may be legally possible, proper source-of-funds documentation, advance legal preparation and long-term contractual planning remain extremely important.

For this reason, House & Condo Lawyer generally recommends preparing a properly drafted Prenuptial Agreement clearly identifying investment funds, ownership intentions, responsibilities and long-term obligations between the parties.

4) Your Existing Thai Company

Some investors may choose to use their own Thai company to hold the underlying ownership structure.

However, investors should ensure that the company conducts genuine business activities in Thailand, possesses real operational income and does not exist solely for property holding purposes.

Proper tax planning, accounting consistency and source-of-funds documentation also remain essential.

House & Condo Lawyer generally does NOT recommend the use of nominee arrangements or artificial shareholder structures created solely to circumvent foreign ownership restrictions under Thai law.

Common nominee warning signs may include:

• unknown shareholders,
• shareholders without sufficient income,
• individuals with no meaningful tax history,
• or shareholders appearing across multiple unrelated companies.

Improper nominee arrangements may create substantial future risks involving criminal exposure, retroactive tax assessment, ownership disputes, inheritance complications and forced asset disposal.

For sophisticated investors, the important issue is not merely whether the structure works today — but whether the structure is professionally designed to remain legally sustainable in the future.

---

Many foreign investors assume that legal risks arise only when laws change.

In Thailand, that is not always the case.

In reality, many property-related laws have remained largely unchanged for years — and in some cases, decades. The more significant change is often not the law itself, but how government authorities interpret, enforce, and prioritize existing laws.

Historically, certain ownership structures, tax arrangements, and business practices may have operated for many years with little scrutiny. However, when a particular issue becomes widespread, attracts regulatory attention, or begins to undermine the purpose of existing laws, enforcement often becomes significantly stricter.

The law may remain the same.

The enforcement may not.

---

One of the most significant developments in recent years is not legal reform, but technology.

As a result, information that was once fragmented across multiple government departments is becoming easier to compare, cross-reference, and analyze.

This trend is not limited to Thailand. Governments worldwide are investing heavily in digital infrastructure, data integration, and AI-powered monitoring tools to enhance compliance and enforcement capabilities.

For property investors, this is particularly relevant where information may overlap between:

In practical terms, arrangements that may have attracted little attention in the past can now become far more visible through digital review and data matching.

The issue is often not whether a structure could be established years ago.

The issue is whether it can withstand today’s level of transparency, scrutiny, and regulatory review.

---

THE KEY QUESTION IS NOT:

“CAN THIS STRUCTURE BE REGISTERED TODAY?”

THE MORE IMPORTANT QUESTION IS:

“WILL THIS STRUCTURE STILL BE DEFENSIBLE 10, 20, OR 30 YEARS FROM NOW?”

For this reason, many foreign investors now place greater emphasis on legal certainty, transparency, succession planning, tax compliance, and professionally structured ownership arrangements when investing in Thailand.

Sap-Ing-Sith is only one of several legal structures available in Thailand. Depending on the investment objective and personal circumstances involved, alternative structures such as Long-Term Leasehold, Superficies, Usufruct, Condominium Ownership, Thai Spouse Structures or Legitimate Holding Company arrangements may also be considered.

However, due to increasing scrutiny concerning nominee arrangements and foreign land holding structures, Land Office officials may refuse registration where the structure appears inconsistent with Thai law or involves suspected nominee ownership.

Because each investor’s situation is different, foreign investors should consult experienced Thailand property lawyers before proceeding with any ownership structure or registration strategy. Improper structuring may result in unnecessary costs, failed registration, retroactive legal exposure or even the loss of the property investment itself.

Can Sap-Ing-Sith be inherited?

Yes. Sap-Ing-Sith may form part of long-term inheritance and succession planning structures.

Can Sap-Ing-Sith be renewed after 30 years?

Under current Thai law, Sap-Ing-Sith may be registered for a period not exceeding 30 years. Any future renewal or re-establishment would depend upon the legal structure, agreements between the parties and the applicable laws and policies in effect at that time.

What happens after the 30-year registration period expires?

Upon expiry, the Sap-Ing-Sith right itself terminates in accordance with the law. For this reason, long-term contractual planning, succession planning and future ownership arrangements should be carefully reviewed in advance during the initial structuring stage

Can Sap-Ing-Sith be sold or transferred?

Yes. Sap-Ing-Sith may generally be transferred, assigned or registered in favor of another person, subject to applicable legal requirements and Land Office procedures.

Can foreigners obtain financing or mortgage Sap-Ing-Sith rights?

Under Thai law, Sap-Ing-Sith rights may legally be mortgaged or used as collateral. However, financing availability depends upon the lending institution, internal bank policies and the overall investment structure involved.

Can developers establish Sap-Ing-Sith structures for foreign buyers?

Yes. Certain developers and property owners may establish Sap-Ing-Sith structures as part of long-term foreign investment arrangements. However, the legal structure, tax implications and ownership arrangements should always be reviewed carefully before proceeding.

What are the tax risks associated with Sap-Ing-Sith structures?

The tax implications depend heavily on the transaction structure, parties involved, ownership arrangements, payment flows and the overall investment design. Professional legal and tax analysis is strongly recommended before registration.
