90-Year Lease in Thailand: Is It Legal? What Buyers Must Know in 2026
By THAI.ESTATE Editorial Team13 min read
A '90-year lease' in Thailand is a marketing term, not a single legal instrument. Thai law caps a registered lease at 30 years. What developers sell as a 90-year lease is three back-to-back 30-year periods, each written as a separate contractual promise to renew. The first lease is registered at the Land Office and is legally enforceable. The second and third periods are contractual renewal promises only. Understanding this distinction before you reserve can protect your money and your exit options.
This guide explains exactly what you get, what you do not get, and how the 90-year structure compares with freehold condo ownership for the four most common foreign buyer profiles in Thailand as of 2026.
Quick answer
- Thai law (Land Code, Section 540) limits any single registered lease to 30 years. A 90-year lease is three consecutive 30-year contracts, not one instrument.
- Only the first 30-year term is registered at the Land Office and appears on the title deed (chanote - the highest-grade Thai land title, equivalent to full freehold for Thai nationals). The remaining two terms exist as contract clauses.
- A renewal clause binds the original landowner but does not automatically bind a new owner if the land is sold. A buyer of the land takes subject to the registered lease only.
- The '90-year' marketing promise is not automatically enforceable beyond the first registered term without additional legal protections in the contract.
- Freehold condo ownership under the Condominium Act gives a foreign buyer perpetual title, but only within the 49% foreign quota for each building.
- As of 2026, no legislative change has extended the registered lease maximum beyond 30 years for residential property.
Options and scenarios
Option 1: Registered 30-year lease (the legal reality behind '90-year' marketing)
When you buy a leasehold villa or land plot in Thailand, the developer or landowner registers a 30-year lease at the Local Land Office. This registration is what gives you legal standing. It appears on the back of the chanote and is binding on the current landowner and any future buyer of that land, because Thai property law requires buyers to take subject to registered encumbrances.
The renewal clauses for years 31-60 and 61-90 sit inside the sale-and-purchase agreement or a separate lease agreement. They are binding contracts between you and the original lessor. If the lessor sells the land to a third party after your first term ends, that third party has no legal obligation to honour the renewal unless the renewal terms are also registered, or unless the new owner expressly assumes the obligation in writing at the time of purchase.
This is the single most important risk in the 90-year lease structure. It is not theoretical. Land in popular areas of Phuket, Koh Samui, and Chiang Mai has changed hands, and lessees have faced disputes at renewal time.
What a well-drafted lease should contain:
- A registered first-term lease at the Land Office for 30 years
- A pre-paid or clearly funded renewal mechanism (some developers collect all three terms' ground rent upfront)
- A right of first refusal or a mortgage over the land in favour of the lessee as security
- A clause confirming that any sale of the land by the lessor is conditional on the buyer assuming all renewal obligations in writing
- A notarised or Thailand-law-governed arbitration clause for dispute resolution
Without these elements, you have a 30-year lease and a contractual promise for two more - which is not the same as a 90-year lease.
Option 2: Freehold condominium ownership
Under the Condominium Act, a foreign national can hold freehold title to a unit in a registered condominium building. The foreign ownership quota is 49% of the total sellable floor area of any single building. This is not a quota per floor or per project phase. It is calculated across the entire building.
Freehold here means perpetual ownership. You receive a title document called a condominium unit title deed (also called a blue book or tabien ban in Thai, though that term technically refers to the household registration). The ownership does not expire. You can sell, bequeath, or mortgage it without time restrictions.
The practical constraint is quota. In high-demand buildings in central Phuket, Pattaya, or Bangkok, the foreign quota is often sold out at launch. Once quota is gone, new foreign buyers cannot acquire freehold in that building. Some buyers then accept a leasehold unit in the same building, at a lower price, but with all the risks described above.
Foreign quota mechanics in 2026: The 49% rule is enforced at the point of Land Office registration. To register, a foreign buyer must show a Foreign Exchange Transaction (FET) certificate - a document from a Thai bank confirming that the purchase funds arrived in Thailand as foreign currency and were converted to Thai baht. Without an FET, the Land Office will not register foreign freehold ownership.
Option 3: Company-held land (not recommended without legal advice)
Some buyers use a Thai limited company to hold land that is otherwise unavailable to foreigners. As of 2026, Thai authorities scrutinise nominee structures where Thai shareholders hold shares on behalf of a foreign buyer with no genuine business purpose. This route carries regulatory and legal risk. The THAI.ESTATE Editorial Team does not recommend this route without a qualified Thai lawyer reviewing the full structure before commitment.
Option 4: Long-term lease under the Industrial Estate Authority or BOI promotion
For investment-grade real estate above certain thresholds, the Board of Investment (BOI) and related agencies offer extended land ownership or lease rights to qualifying foreign investors. As of 2026, these are project-specific and do not apply to standard residential purchases. They are mentioned here for completeness; most readers buying a villa or condo will not qualify.

Risks and mistakes
Risk 1: Trusting the '90-year' label without reading the contract
Developers and agents use '90-year lease' as a marketing shorthand. It signals long-term security to buyers unfamiliar with Thai law. Always ask to see the actual lease agreement and the land title (chanote) before reserving. Confirm which terms are registered and which are contractual.
Risk 2: No security against land sale during the lease
If the developer sells the underlying land - to clear debt, through a company restructuring, or in a distressed situation - the new owner is bound only by the registered first term. Your renewal rights for years 31-90 depend on what the new owner agrees to. Without a registered mortgage or right of first refusal over the land in your favour, your position is weak.
Ask your lawyer to check whether the land is mortgaged to a bank. If it is, and the developer defaults, the bank forecloses on free-and-clear land, and your lease survives only for the registered term.
Risk 3: Pre-paid rent and developer insolvency
Some structures require you to pay all 90 years of ground rent upfront (often bundled into the purchase price). If the developer becomes insolvent before the building is completed, you have paid for a lease that may not exist. Thailand does not have traditional escrow protection for off-plan buyers. Review the payment schedule with a lawyer and understand what security, if any, protects your stage payments.
Risk 4: Resale to another foreign buyer
A leasehold property is harder to sell. The next buyer gets only the years remaining on the registered term. A property with 22 years left on a 30-year lease is materially less attractive than one with 28 years left. Pricing adjusts accordingly. Resale timelines are longer in the leasehold segment, per market observations in Phuket and Samui as of 2026.
Risk 5: Renovation and structural change rights
Lease agreements vary widely on what improvements you may make to the structure. Some restrict alterations without the lessor's written consent. Others allow full renovation but require you to return the property in its original condition at lease end - meaning you effectively fund improvements for the landowner. Read this clause before signing.
Risk 6: Inheritance and succession
A lease passes to your heirs for the remaining registered term. However, the contractual renewal obligations (terms 2 and 3 in a 90-year structure) may not pass automatically. Thai succession law and the terms of the lease agreement interact here. If you are buying as part of estate planning, a Thai lawyer must review the inheritance clause specifically.
Risk 7: Foreign quota sold out at point of resale
For freehold condos, if you later want to sell to another foreign buyer, the building's 49% quota must have an available slot. If the quota is full at the time of your sale, you can only sell to a Thai buyer or a Thai company - which narrows your buyer pool and may compress the sale price.
Mistake: Signing the reservation agreement without legal review
In Thailand, a reservation deposit (typically 50,000 to 200,000 baht as of 2026) is often non-refundable. Some buyers sign the reservation form before engaging a lawyer. By the time the lawyer reviews the full sale-and-purchase agreement, the buyer has already committed funds. Always engage a lawyer before paying any reservation deposit.
FAQ
Is a 90-year lease in Thailand legally recognised?
No, not as a single instrument. Thai law caps a registered lease at 30 years under Section 540 of the Land Code. A 90-year lease is three consecutive 30-year contracts. Only the first 30-year term is registered at the Land Office and has full legal standing. The remaining two terms are contractual renewal promises between you and the original landowner.
What happens to my lease if the developer sells the land?
The registered first term survives a land sale because Thai law requires buyers to take subject to registered encumbrances. The renewal obligations for years 31-60 and 61-90 are contractual only. A new landowner is not automatically bound by them unless they expressly assumed those obligations in writing at the time of purchase, or unless additional security (such as a registered mortgage over the land in your favour) was in place.
Can I register all three 30-year terms at the Land Office now?
No. The Land Code does not permit advance registration of a future lease that has not yet commenced. You can register the first 30-year term now. The second and third terms can only be registered when the previous term ends and a new lease agreement is executed. There is no legal mechanism to lock in all three terms today through Land Office registration.
Is leasehold always cheaper than freehold in Thailand?
Generally yes, by a material margin. Per market estimates in 2026, leasehold villas and land plots are priced roughly 20-40% below comparable freehold or freehold-equivalent assets, partly because of the resale discount and partly because financing options are limited. The discount varies by location, remaining lease term, and the quality of the renewal protections in the contract.
What is the difference between a leasehold condo and a leasehold villa?
A leasehold condo unit sits within a registered condominium building. The building itself is freehold; you lease your individual unit from the developer. A leasehold villa or house involves leasing the land and the structure on it. In both cases, the 30-year registered limit applies. The practical risks are similar, but villa leaseholders also need to consider the land owner's ability to sell the underlying land.
Do I need an FET certificate for a leasehold purchase?
A Foreign Exchange Transaction (FET) certificate - a document from a Thai bank confirming that funds arrived from abroad in foreign currency - is required for freehold condo purchases to qualify for Land Office registration. For leasehold purchases, an FET is not a legal requirement for the transaction itself, but it is good practice to bring funds through the banking system properly documented, as it simplifies any future sale or repatriation of proceeds.
Can I get a Thai bank mortgage on a leasehold property?
Rarely. Thai banks generally do not lend to foreign buyers on residential property, and leasehold security is even less attractive to lenders than freehold. Some developer financing or international private banking exists for high-value purchases, but you should plan for cash or offshore financing when buying leasehold property in Thailand.
Which buyer profile is better suited to leasehold versus freehold?
A holiday-home buyer who wants a larger villa footprint at lower cost, and does not prioritise resale or inheritance, can work with a well-structured 30+30+30 lease if legal protections are in place. A yield investor typically prefers freehold condos for liquidity and financing optionality. A retiree planning to stay long-term needs clarity on the renewal mechanism and should weight security of tenure very highly. A family relocating should prioritise freehold for inheritance simplicity and the ability to renovate freely. The comparison table in this guide maps these factors directly.
What questions must I put to the seller's lawyer before reserving?
Ask: Is the land mortgaged to any bank or creditor? Who is the registered landowner and is that the same entity as the developer? Is the lease registered at the Land Office and can I see the chanote with the lease notation? What security protects my renewal rights for years 31-90? What happens to my stage payments if the developer becomes insolvent before completion? What renovation rights does the lease grant and what are the reinstatement obligations at lease end?
Has Thailand considered extending the 30-year lease cap?
As of 2026, no legislation has passed extending the 30-year maximum for standard residential leases. Proposals have circulated periodically, including a suggested 50-year cap for tourism-related properties, but none have become law. Do not make a purchase decision based on anticipated legislative change. Base your decision on the law as it stands today.
