The 30-Year Maximum Lease and the End of "30+30+30": Why Pre-Agreed Lease Renewals Are Now Void and Unenforceable in Thailand

Supreme Court Judgment No. 4655/2566 · Civil & Commercial Code, Section 540

Under Thai law, the maximum lease term for immovable property (land, houses, condominium units) is 30 years. This ceiling is fixed by Section 540 of the Civil and Commercial Code and cannot be overridden by private contract.

On 18 March 2025, Thailand's Supreme Court (Dika) handed down Judgment No. 4655/2566, holding that the popular "30+30+30" lease structure — a 30-year lease combined with two pre-signed, pre-paid 30-year extensions — is void and unenforceable. Pre-agreed automatic renewals are merely personal contractual promises; they do not bind the land, do not bind future owners, and cannot be enforced in court.

KEY TAKEAWAY

Foreign buyers can rely on a single registered 30-year lease. Anything marketed as "60 years", "90 years" or "30+30+30" should be treated as unenforceable beyond the first 30 years, regardless of how the contract is drafted, paid or registered.

The 30-Year Maximum: Section 540 of the Civil and Commercial Code

Section 540 of the Civil and Commercial Code is the cornerstone of Thai leasehold law. It provides, in substance:

"The duration of a hire of immovable property cannot exceed thirty years. If it is made for a longer period, such period shall be reduced to thirty years. The aforesaid period may be renewed, but it must not exceed thirty years from the time of renewal."

Three points follow directly from the wording of the statute:

30 Years Is an Absolute Ceiling

Any lease purporting to run longer is automatically reduced to 30 years by operation of law.

Renewal Is Permitted, but Not Pre-Bookable

A new 30-year term can be granted, but only at the time of renewal — not pre-signed decades in advance.

Registration Is Mandatory Beyond 3 Years

Under Section 538, any lease over three years must be in writing and registered at the Land Office, otherwise it is enforceable for only three years.

The Land Department will register a lease for a maximum of 30 years. It will not register a 60-year or 90-year lease, and Departmental Instruction No. มท 0515.1/ว 8867 (24 April 2008) specifically directs officials to refuse registration of pre-paid or automatic renewal arrangements that exceed the 30-year limit.

What the "30+30+30" Structure Promised

For more than two decades, foreign buyers in Phuket, Samui, Hua Hin, Pattaya and Chiang Mai have been sold villas, pool houses and townhouses on a so-called "30+30+30" basis. The package typically combines:

• An initial 30-year lease, registered at the Land Office

• Two pre-signed renewal agreements (or option clauses) for two further 30-year terms

• Up-front payment of all rent for the full 90-year period, often described as a "purchase price"

The buyer was told the structure delivered "90 years of secure tenure, near-equivalent to freehold." In reality, only the first 30 years was ever a registered property right. Everything after year 30 depended on private promises that the courts have now refused to enforce.

Why Marketing Language Has Misled Buyers

Brochures often described the renewals as "guaranteed" or "automatic." Thai law recognises no such concept for immovable property. A registered lease is a property right; a renewal promise is, at best, a personal contract — and now, when used to circumvent Section 540, it is no contract at all.

Supreme Court Judgment No. 4655/2566 (18 March 2025)

In a ruling that originated from a property dispute in Phuket, Thailand's Supreme Court (ศาลฎีกา) issued Judgment No. 4655/2566 on 18 March 2025. The case concerned a 30-year lease coupled with two pre-signed 30-year extensions, with the lessee having paid the rent for the entire 90-year period in a single lump sum shortly after signing.

Procedural History

• The Court of First Instance sided with the lessee, treating the extension clauses as enforceable contractual promises.

• The Court of Appeal reversed, holding that the structure circumvented Section 540.

• The Supreme Court upheld the Court of Appeal and dismissed the lessee's claim, declaring the renewal clauses void.

The Court's Reasoning

The Supreme Court focused on substance over form. The simultaneous execution of the lease and the two renewals, together with the single up-front payment for the entire 90-year period, demonstrated a "premeditated intention to lease for 90 years — not 30."

Allowing such a scheme to stand, the Court held, would render Section 540 meaningless. The 30-year ceiling exists for reasons of public policy: to prevent the indefinite removal of land from economic circulation, to protect future owners from being bound by commitments made decades earlier, and to protect lessees from speculative arrangements over excessively long durations.

What the Court Actually Decided

Issue | Court's Holding

Initial 30-year registered lease

Valid and enforceable for the full 30-year term, binding on the land and on any future owner (Section 569 CCC).

Pre-signed, pre-paid renewal clauses

Void and unenforceable. A scheme designed to circumvent Section 540 cannot be saved by labelling it an 'option' or 'contractual right.'

Status of the renewal as a property right

Not a real right. A renewal promise that cannot be registered in advance does not attach to the land and does not bind a successor owner.

Effect of pre-payment of rent

Pre-payment is evidence of the parties' intention to evade the 30-year cap; it does not cure the illegality.

Lump-sum, simultaneous structuring

Treated by the Court as proof of "premeditated intention" to lease for 90 years from inception.

The judgment is wrapped in cautious language about the specific facts of the case, but the practical effect is unambiguous: the "30+30+30" model has no future. Lower courts are already applying the precedent.

Why Renewal Promises Cannot Bind the Land

Thai property law distinguishes sharply between two categories of right:

Registered Property Right

A right attached to the land itself (e.g., a registered 30-year lease, usufruct, superficies, mortgage). Binds future owners — follows the land regardless of who owns it (Section 569 CCC). Registrable at the Land Office; registration is what makes it a property right. The first 30 years of a properly registered lease remain fully secure.

Personal Contractual Promise

A promise between two specific people (e.g., a pre-signed renewal letter). Does not bind future owners — a new owner is not party to it. Not registrable at the Land Office. Pre-agreed 30-year renewals are void where used to circumvent Section 540.

The consequence is straightforward. Even if the original landowner is willing and solvent in 30 years' time, the renewal will be enforceable only as a personal promise between the two original parties — and not at all if the land has changed hands, the owner has died, the company has been wound up, or the political climate has shifted.

Practical Consequences for Foreign Property Buyers in Thailand

If You Are Buying a Leasehold Villa Today

• Treat the contract as a 30-year lease, full stop. Price it accordingly.

• Ensure the lease is registered at the Land Office in your name, in writing, in Thai, with all critical clauses faithfully translated.

• Do not pay extra for "year 31 to year 90." Under Judgment 4655/2566 you are paying for a promise the courts will not enforce.

• Negotiate strong structural protections: right of first refusal to purchase, transfer rights, sub-lease rights, succession rights for heirs, and a clear exit/compensation mechanism if the lessor sells.

• For genuinely long horizons, consider lawful alternatives: BOI-promoted company, LTR-linked structures, condominium freehold within the 49% foreign quota, or ownership through a properly capitalised Thai company with credible commercial substance.

If You Already Own a Property Under a 30+30+30 Structure

• Your existing first 30-year term remains valid if it was properly registered. You retain full possession and use rights for the unexpired balance.

• The second and third 30-year renewals are now legally hollow. They are unenforceable against the current landowner if used to evade Section 540, and almost certainly unenforceable against any new owner.

• You may have contractual claims against the original developer or seller for misrepresentation, depending on how the property was marketed.

• Where possible, seek to convert the arrangement into more secure rights: a fresh registered renewal at the appropriate time, a usufruct or superficies for the structure, condominium ownership where the project qualifies for licensed conversion, or restructuring through a BOI or LTR-eligible vehicle.

Important: Do not panic, and do not assume your existing lease is worthless. The first 30 years — the only part the Land Office ever registered — is unaffected. The risk lies entirely beyond year 30, and you may have many years to plan around it. Each case turns on the wording of the specific contracts, the title documents and the corporate structure of the lessor.

Frequently Asked Questions About Thai Property Leases

Is my current 30-year lease still valid?

Yes. If your initial 30-year lease was properly registered at the Land Office, it is unaffected by Judgment 4655/2566. The Court only struck down the pre-agreed renewals; it did not disturb the underlying 30-year term.

Can I just sign a new 30-year lease at year 30?

Legally, yes — a fresh 30-year renewal is permitted under Section 540, but only when the existing term is at or near expiry. The catch is that the renewal is at the discretion of whoever owns the land at that time. You cannot bind that future owner today.

What if my lease registration document refers to the renewals?

The Land Office only registers the first 30-year term. References to future renewals in side-letters or unregistered annexes do not create a real right and, after Judgment 4655/2566, are very unlikely to be enforced if the structure was designed to evade Section 540.

Does the ruling apply to commercial leases too?

Section 540 applies to leases of immovable property generally. Commercial premises, hotels, retail and industrial leases are subject to the same 30-year ceiling unless they fall within specific statutes (for example, Industrial Estate Authority leases or BOI-promoted activities).

Is there any way to get more than 30 years on a villa?

Not by stacking renewals. The realistic options are condominium freehold (where applicable), BOI-linked land ownership, or a single registered 30-year lease backed by carefully drafted protective rights and a credible succession plan for renewal at year 30.
