90-Year Lease in Thailand: Is It Legal and Safe in 2026

A '90-year lease' in Thailand is a marketing term, not a single legal instrument. Thai law caps a registered land lease at 30 years. What developers sell as '90 years' is three consecutive 30-year terms stacked together, with the second and third terms written as contractual renewal promises. As of 2026, that structure is widely used across Phuket, Koh Samui, Chiang Mai and other popular markets. Whether it is safe depends entirely on how the documents are drafted and registered.

The short answer: the first 30-year term is legally enforceable once registered at the Land Office. The second and third terms are contractual promises between you and the current landowner. They are not automatically binding on a new landowner if the land is sold or transferred. That gap between marketing promise and legal reality is where buyers lose money.

Quick answer

  • Thai law (the Civil and Commercial Code) limits a single registered lease to 30 years maximum
  • A '90-year lease' means three 30-year terms; only the first term can be registered at the Land Office today
  • Renewal clauses in the lease contract bind the original lessor, but do not bind a new landowner unless the buyer takes extra protective steps
  • A well-drafted lease includes pre-registration of a superficies right or a recorded annotation, but most off-plan contracts do not
  • As of 2026, Thai courts have upheld renewal obligations between original parties, but enforcement against a successor landowner remains legally uncertain
  • The safest long-term structure for a foreign buyer wanting secure tenure beyond 30 years is freehold condo ownership under the Condominium Act, where foreign quota allows up to 49% of total unit floor space

Options and scenarios

Scenario 1: Single registered 30-year lease

This is the most straightforward leasehold structure. You pay a lump sum or annual rent. The lease is registered at the Land Office against the title deed (chanote - the highest grade of Thai land title, equivalent to full freehold title for the land itself). Registration gives you a real right in rem: it appears on the chanote and binds third parties, including a buyer of the land, for the registered term only.

You can occupy, rent out and in most cases renovate within the scope the lease permits. You cannot sell the leasehold interest without the lessor's written consent unless the lease explicitly grants assignability. At the end of 30 years, you have no automatic right to renew unless the lease contains a renewal clause and the land has not changed hands.

Best for: Holiday-home buyers who want a fixed tenure and are comfortable with a 30-year horizon, or buyers who plan to sell the leasehold interest within that window.

Scenario 2: Three-term '90-year' lease with contractual renewal clauses

This is the structure most commonly marketed to foreign buyers in resort areas as of 2026. The signed agreement covers three periods of 30 years each. The first term is registered. The renewal clauses state that the lessor (and their heirs or assigns) will cooperate to register each subsequent term when it begins.

The legal position: Thai contract law does allow renewal obligations. If the same landowner holds the land for 90 years, the renewal clauses are enforceable in Thai court. The problem arises when the land changes hands through sale, inheritance, bankruptcy or corporate restructuring. A new landowner who did not sign the original lease is generally not bound by unregistered future terms.

Some developers add protective layers: a usufruct right (the right to use and benefit from the property, registerable at the Land Office for up to 30 years or for the holder's lifetime), a superficies right (the right to own buildings on land belonging to someone else, also registerable), or a second contract with a company controlled by the developer pledging to renew. Each layer adds cost and complexity but improves protection.

Best for: Buyers who have verified the developer's land ownership structure, confirmed the renewal obligation is registered or secured by an additional real right, and accept residual legal uncertainty beyond year 30.

Scenario 3: Leasehold through a Thai company structure

Some buyers are advised to hold land through a Thai-majority company. This is outside the scope of the 90-year lease question but relevant context: the Land Code prohibits foreigners from owning land directly, but a company majority-owned by Thai nationals can hold land. As of 2026, Thai authorities continue to scrutinize nominee shareholder arrangements. Using Thai nominees to circumvent foreign ownership restrictions is illegal under the Land Code and the Foreign Business Act. This guide does not recommend that route.

Scenario 4: Freehold condo as the alternative to leasehold

Foreign buyers can own a condominium unit outright (freehold) under the Condominium Act, provided the building's foreign quota - meaning the maximum percentage of total floor space that can be foreign-owned - does not exceed 49%. Ownership is registered on a title document called a chanote or a condominium-specific title (tor dor 5). This is the only direct freehold land-touching ownership route legally available to most foreign individuals in Thailand. For buyers whose goal is long-term security, freehold condo ownership eliminates the renewal risk entirely.

Best for: Retirees, families relocating, and yield investors who want full ownership rights, simpler inheritance and easier resale to other foreign buyers.

Scenario 5: Leasehold with superficies right

A superficies right (granted under Sections 1410-1416 of the Civil and Commercial Code) allows you to own the building on leased land separately from the land itself. It is registerable at the Land Office for up to 30 years or for the holder's lifetime. Combined with a 30-year lease, it gives you registered ownership of the structure. If the land is sold, the new landowner is bound by the registered superficies for its remaining term. This does not solve the 30-year cap, but it does protect your building investment during the registered period.

Risks and mistakes

The renewal clause is not registered and the land is sold

This is the most common scenario where buyers lose rights. The original developer sells the underlying land to a new entity. The new entity is not a signatory to your lease renewal promise. Thai courts have generally held that the new landowner takes the land subject to the registered first lease term but is not obligated by unregistered future terms. You may have a claim against the original lessor for breach of contract, but recovering damages from an offshore developer is difficult and slow.

What to check: Ask the seller's lawyer to confirm what charge or annotation, if any, appears on the chanote for the second and third terms. If nothing is registered, the renewal promise is an unsecured contractual right only.

The developer-owned company structure adds hidden risk

Many resort villas are sold on land held by a developer company. The lease is between you and that company. If the company is wound up, changes directors or is restructured, the chain of obligation for renewal can break. Ask for a certificate of company registration, the company's shareholder structure and any existing charges on the land before reserving.

Superficies and usufruct are often omitted to save cost

Developers sometimes offer the 90-year lease without a superficies right because registration costs money and slows the process. Without a registered superficies, your ownership of the building itself is not secured against third parties. Insist on it in writing before signing.

Lease assignability is often restricted

Many standard Thai lease contracts prohibit assignment without the lessor's written consent. If you want to sell your leasehold interest before year 30, you may need the lessor to cooperate. Some developers charge a transfer fee of 1-2% of the original purchase price (market practice, indicative 2026 figures) to consent to an assignment. Confirm this in the contract before signing.

Currency and remittance rules affect exit

Foreign buyers who import funds to buy a condominium unit must receive a Foreign Exchange Transaction (FET) form - a bank document proving foreign currency was converted into Thai baht for the purchase. The FET form allows you to repatriate sale proceeds later. For leasehold properties, remittance rules are less standardized. Confirm with a Thai bank before purchase how you will document and later repatriate your investment.

Inheritance is not automatic for foreign heirs

A leasehold interest forms part of your estate but the lease contract may contain clauses restricting transfer on death. Even where inheritance is contractually permitted, a foreign heir must go through Thai probate, which can take one to three years (indicative timeframe based on typical court practice in 2026). Freehold condo units are easier to transfer through probate because the title is clear. For leasehold villas, have a Thai lawyer review the inheritance clause before you sign.

Questions you must put to the seller's lawyer before reserving

The following questions are practical and non-negotiable. Get written answers, not verbal reassurances.

  • Is the first 30-year lease term already registered on the chanote, or will it be registered on or before completion?
  • What legal instrument secures the second and third 30-year terms - is anything registered on the chanote for those periods?
  • Does the lease include a registered superficies right covering the building?
  • Who currently owns the land - a company or an individual? If a company, what is the shareholding structure and are there any existing charges on the land?
  • Is the lease assignable without the lessor's consent? If consent is needed, is there a contractual cap on any transfer fee?
  • On my death, can my heirs inherit the leasehold interest, and is any consent from the lessor required?
  • How do I document the foreign currency import for this purchase, and what does the FET process look like for this type of asset?

FAQ

Is a 90-year lease legal in Thailand?

The term '90-year lease' is legal as a contractual arrangement, but the underlying law caps any single registered lease at 30 years. The 90-year figure refers to three consecutive 30-year terms. Only the first term can be registered at the Land Office. The second and third terms are contractual renewal promises. They are legally valid between the original parties but do not automatically bind a new landowner.

What happens when the first 30 years expire?

At the end of year 30, the registered lease expires. If the renewal clause is enforceable and the original lessor or their legal successor still owns the land, you can require them to register a new 30-year lease. If the land has changed hands and the new owner is not bound by the renewal clause, you may have a breach-of-contract claim against the original lessor but no automatic right to remain on the property.

Can a developer guarantee the full 90 years in writing?

A developer can write a contractual guarantee into the lease agreement. That guarantee is binding on the developer as a legal party. It is not binding on a third party who later purchases the land unless additional rights are registered on the chanote. Written guarantees from the developer are worth having, but they are not the same as a registered right.

Is a 30-year lease safer than a 90-year lease?

A properly registered 30-year lease with a registered superficies right is often more secure in practice than a 90-year lease that only registers the first term and relies on unregistered renewal promises for years 31-90. Clarity and registration matter more than the headline number of years.

Can I get a mortgage on a leasehold property in Thailand as a foreigner?

Thai banks generally do not lend to foreign individuals against leasehold property in Thailand as of 2026. Some developer finance schemes exist, but these are private arrangements with the seller, not regulated bank mortgages. Buyers typically purchase with cash or foreign financing secured against assets in their home country.

What is a chanote and why does it matter for a leasehold?

A chanote (Nor Sor 4 Jor) is Thailand's highest grade of land title document. It confirms precise GPS-surveyed boundaries and allows full registration of rights including leases, superficies and mortgages. Always confirm the land underlying your lease is held on a chanote, not on a lower-grade document such as Nor Sor 3 or Sor Por Kor, which offer fewer registration options and weaker boundary certainty.

How much does it cost to register a lease in Thailand?

As of 2026, the Land Office charges a registration fee of 1% of the declared lease value plus a stamp duty of 0.1%, based on standard practice. The declared value is often negotiated between parties. These figures are indicative; confirm current rates with a Thai lawyer or the relevant Land Office before completion.

What is a superficies right and do I need one?

A superficies right (granted under the Civil and Commercial Code) is a registered right to own buildings on land that belongs to someone else. It is registerable for up to 30 years or for the holder's lifetime. If you are buying a villa or house on leased land, a registered superficies gives you a legal record that you own the structure separately from the land. This protects you if the land changes hands during the registered period. It does not extend your tenure beyond 30 years, but it does secure your building investment during that time.

Is freehold always better than leasehold for foreign buyers in Thailand?

For long-term security, yes. Freehold condo ownership under the Condominium Act gives you indefinite ownership, clearer inheritance rights and simpler resale within the foreign quota. Leasehold can make sense for buyers who want a villa or house (where freehold land ownership is not legally available to foreigners), who have a defined time horizon, and who have verified the lease structure with qualified legal advice. The choice depends on your goals, timeline and risk tolerance, not on which headline sounds better.

What buyer profiles fit leasehold versus freehold?

A holiday-home buyer with a 10-20 year horizon who wants a villa in a resort area may accept a well-structured leasehold as a practical option. A retiree or family relocating permanently who wants certainty and ease of inheritance is better served by freehold condo ownership. A yield investor who plans to resell within the foreign quota will find freehold easier to exit. A buyer who cannot access freehold options in their chosen location and has verified the lease documents with an independent Thai lawyer may proceed with leasehold, provided the risks above are understood and accepted in writing.
