Firm annotation
Section 540 is the cap on Thai lease duration. The famous "90-year lease" marketed by some property developers is a myth — it is actually three back-to-back 30-year leases, each requiring renewal by mutual consent and Land-Office registration. Courts have struck down upfront-paid 90-year arrangements as attempts to circumvent §540. SC decisions on renewal options consistently hold that the renewal must be a true new agreement, not a unilateral right of the lessee. For long-term foreign investment, usufruct (life-of-lessee) or superficies (separately registered building right) are more durable than lease-renewal chains.
Residential vs commercial. The 30-year ceiling governs ordinary and residential leases. A genuine commercial or industrial lease can instead run up to 50 years (renewable for up to 50 more) under the Lease of Immovable Property for Commercial and Industrial Purposes Act B.E. 2542 (1999), provided the land is in an approved commercial/industrial area or industrial estate, the investment qualifies (broadly, a commercial investment of at least 20 million baht, or a BOI-eligible industry), and the lease is registered. Renewal is never automatic: it must be a fresh agreement made after the current term ends, and an automatic, prepaid, or pre-agreed renewal that effectively exceeds 30 years is void as a circumvention of §540 (see Supreme Court Decision 4655/2566). One exception binds the parties: where the tenant gives consideration beyond ordinary rent — typically by constructing the building or paying for major improvements — the contract may qualify as a reciprocal agreement (สัญญาต่างตอบแทนยิ่งกว่าสัญญาเช่าธรรมดา). The Supreme Court enforces such a contract between the parties and their heirs even without registration, but it stays a personal right — it does not bind a later good-faith purchaser and cannot defeat the 30-year cap.
Why this matters in practice
Lawyers: A provision purporting to grant a 99-year lease, or perpetual use, is automatically reduced to 30 years — no court order is required. A contractual option to renew after 30 years is valid, but the renewal requires a new written and registered agreement for the renewed term to be enforceable beyond 3 years. Laypeople: The longest enforceable lease of Thai land or buildings is 30 years. At the end, you must negotiate a new lease — your rights do not continue automatically.

Frequently asked questions
Can I sign a lease for 50 years in Thailand?
It depends on the purpose. For an ordinary residential lease, no — Section 540 caps a hire of immovable property at 30 years, and any longer term is automatically reduced to 30. But a lease for genuine commercial or industrial purposes can run up to 50 years under the Lease of Immovable Property for Commercial and Industrial Purposes Act B.E. 2542 (1999), if the conditions are met (the land is in an approved commercial/industrial area or industrial estate, the investment qualifies, and the lease is registered). In both cases the term is a single registered period; a renewal is valid only as a fresh agreement made after the current lease ends — it cannot be automatic or agreed in advance (Supreme Court Decision 4655/2566).
Can a commercial lease in Thailand be 50 years?
Yes. The 30-year limit in Section 540 is the general rule, but the Lease of Immovable Property for Commercial and Industrial Purposes Act B.E. 2542 (1999) allows a lease for commercial or industrial purposes of up to 50 years, renewable for up to another 50 years. It applies only to qualifying activity — broadly, a commercial investment of at least 20 million baht, or an industry eligible for BOI promotion — on property in an approved location, and the lease must be registered with the Land Department.
Is a lease renewal in Thailand automatic?
No. A renewal clause is only an option; the renewal must be executed as a new contract after the current term ends. A renewal that is automatic, prepaid, or agreed in advance to create an effective term beyond 30 years is void as an attempt to circumvent Section 540 (Supreme Court Decision 4655/2566). The lessor cannot be forced to renew, and the Supreme Court has refused to enforce an advance renewal even as a personal right where its purpose was to defeat the 30-year cap.
What is a reciprocal agreement, and can it bind the parties beyond an ordinary lease?
A "reciprocal contract more than an ordinary lease" (สัญญาต่างตอบแทนยิ่งกว่าสัญญาเช่าธรรมดา) arises where the tenant gives consideration beyond ordinary rent — for example, constructing the building or paying for major improvements. The Supreme Court treats it as a binding personal contract: it is enforceable between the parties even if it was not registered, and it passes to the parties' heirs rather than ending automatically. It remains a personal right, so it does not bind a later good-faith buyer of the land, and it cannot be used to evade the 30-year cap. Whether a contract qualifies is decided case by case.
