Can a Thai Lease Be Renewed? The 30-Year Rule Explained

A foreigner generally cannot own land in Thailand, so a registered lease is one of the few lawful ways to hold a villa, and many are sold with a line about renewal: 30 years, then another 30, sometimes a third. The first 30 years are a right the law protects. Everything after that is a promise, and in 2023 Thailand’s Supreme Court showed how little it is worth when it stretches a lease past the legal limit. So the question to ask of any Thailand leasehold is not whether it mentions a 30-year renewal but whether that renewal is a right, and what a buyer can rely on if it is not. Leasehold against freehold in general is covered in our guide to the pros and cons of buying leasehold property.

What does a 30-year lease actually give you?

A Thai lease is a contract of hire, not ownership: the landowner lets you use the land, and usually the house on it, for a limited period in return for rent. A lease of more than three years is enforceable for only three unless it is made in writing and registered with the Land Office (Civil and Commercial Code, section 538), and section 540 caps the term at 30 years, cutting any longer term down to 30. A separate 1999 Act allows longer leases, but only for commercial and industrial use (a 2023 Land Development Department sheet). Unless the contract says otherwise you cannot sublet the property or pass the lease on (section 544), and when the term ends the lease simply ends, with no notice needed (section 564).

A registered lease therefore gives you a secure, exclusive right to use a property for its registered term, at most three decades, and nothing after that. Our legal guide to property ownership for foreigners explains why a lease is needed at all, and the Thai-company arrangements often used instead are the target of the 2026 nominee company crackdown.

Can a Thai lease be renewed, and what did the 2023 ruling change?

It can, but only for a new term that starts when the old one ends. Section 540 says the 30-year period "may be renewed, but it must not exceed thirty years from the time of renewal", so the law allows one term at a time, not a stack of terms fixed and paid for at the start. Supreme Court Decision 4655/2566 shows what happens to the stack. In 1990 a Phuket landowner leased her land and house for 30 years for 1,500,000 THB, and the same day the tenant agreed to pay 1,200,000 THB more for two further 30-year terms, 600,000 THB of which he had paid. When the first term ended in 2020 she asked him to leave. The trial court ordered her to register a new term; the Court of Appeal reversed that, and the Supreme Court upheld the eviction, holding that the promised renewals circumvented section 540 and awarding her damages of 30,000 THB a month (Addleshaw Goddard).

The firm’s briefing is dated March 2025, which is why the 2023 ruling is sometimes given that year. In the firm’s reading the ruling did not overturn earlier case law but applied the code strictly: an agreement that creates more than 30 years from the outset is void. The court was particularly wary of renewals fixed on the same terms as the first period, which the firm reads as meaning renewal terms may be upheld if they reflect circumstances at the time of renewal; here the later rent had been set in 1990, lower than the first. The court also refused to treat the prepaid renewals as an enforceable personal contract, because that would defeat the 30-year limit by another route.

Nor is a longer lease on the way. The 99-year lease you may have read about, including in our 2025 article on the leasehold reform, was one proposal: a draft amendment to the Sap-Ing-Sith Act, heard by the Department of Lands from 22 August to 5 September 2025, under which, reportedly, only a state agency could grant a right of up to 99 years (Isranews). On 16 September 2025 The Nation, describing it as "99-year leases with land transferred to the Treasury Department in exchange for usage rights", reported that it "will not be pursued further" (The Nation); we have found no record that it has been enacted, and our July 2026 update on the 99-year proposal has the detail.

What is a renewal clause still worth?

Less than it is sold as, but not nothing. A renewal agreed as the first term ends, on terms that reflect the property and the market at that point, is exactly what section 540 allows, and a landowner who wants a good tenant to stay has every reason to sign one. What a clause written today cannot do is guarantee that outcome. A Koh Samui law practice puts it bluntly in its guide to lease terms and renewal: renewal "is not enforceable in a court based on a promise made in a lease signed 30 years ago".

The clause is worth least against a new owner. The same guide cites a 1998 Supreme Court judgment, No. 6763, holding that a renewal option did not bind a buyer of the land, because the agreed term is a lease right while an option to renew is only a contract promise. The law’s own automatic renewal is little comfort either: if you stay on after the term and the owner knowingly does not object, the lease is deemed renewed for an indefinite period (section 570), which either side can end on one rent period’s notice, at most two months (section 566). And never prepay renewals at today’s rent, as the Phuket tenant did. Of the 107 villas and houses we list for sale in Hua Hin, 13 are offered on a lease, among them HV316 at Woodlands Residences at 6,000,000 THB, and 6 more as freehold or leasehold; on a lease, the price buys the years left on the registered term, not the renewal clause.

What happens if the landowner sells or dies?

A registered lease survives both. Section 569 of the code says a lease of immovable property "is not extinguished by the transfer of ownership", and the new owner takes on the old owner’s rights and duties towards you, so a buyer of the land cannot simply evict you. When a landowner dies, the heirs inherit the land with your lease on it, because an estate passes with the deceased’s "rights, duties and liabilities", except those purely personal (sections 1599 and 1600).

That protection covers what the law treats as the lease itself, meaning the term, the rent, the use and any agreed right to sublet. The same Koh Samui practice warns that a new owner, or the landowner’s heirs, are not bound by the previous owner’s contract promises unless they accept them, and it counts among those promises not only renewal but a clause letting the lease pass to your heirs.

What happens to the lease if you die?

That depends on the wording. Thai courts long treated a lease as personal to the tenant, ending on the tenant’s death, and the Land Development Department sheet cited above still describes it that way. No section of the code says so; the rule is case law, and in 2016 the Supreme Court qualified it. Decisions 2939/2559 and 11058/2559 held that a lease allowing the tenant to sublet or assign is not personal, so it passes to the heirs and the landowner cannot evict them, while a lease without that term still ends (Legardy on section 544; a 2023 Thai law journal article). A lease that expressly lets you sublet and assign, and says it continues for your heirs, is therefore far more likely to outlive you than one that is silent.

What should the lease contract say?

Registration at the Land Office for the full term comes first, then an express right to sublet and assign, which section 544 otherwise withholds. The contract should also settle who owns the house, the structure our guide to buying a villa in Hua Hin as a foreigner explains, and on a bare plot, where the house you build will stand on land you only rent, our guide to buying land in Hua Hin covers the title deed the lease is registered against.

Then the contract should treat renewal honestly. Addleshaw Goddard suggests giving the tenant an option, never an automatic renewal, to register a new 30-year term when the current one ends, at the current rent escalated, for example by consumer prices, and paid on registration. At the end of any term the landowner takes over the buildings and pays you their market value, unless a new term is agreed. None of this turns a promise into a right, but it avoids what the court objected to, and it is worth asking for on new and off-plan villas, where the developer writes the lease.

Are there alternatives to a lease?

Three other rights come up, and our guide to Sap-Ing-Sith sets all four side by side. A superficies lets you own buildings on someone else’s land for up to 30 years or for the life of the landowner or the holder (Civil and Commercial Code, sections 1410 to 1412), while a usufruct always ends when the holder dies (section 1418), so it cannot be left to children.

Sap-Ing-Sith, in Thai law since 2019, is a registered right of up to 30 years that can be sold, mortgaged and inherited, but only over Chanote land or a condominium unit. It fixes the transfer and inheritance weaknesses of a lease but not the renewal one, because the Act contains no statutory renewal and an extension needs a new agreement and a new registration. Whichever right you hold, it is worth what is registered, and anything promised after its term is a negotiation still to come.

Looking at villas or land on a lease?

When a villa or plot you like is offered on a lease, ask to see the draft lease and the title deed early, so your lawyer can read the renewal and inheritance clauses before any deposit is paid.

Our guide to Red Mountain, Woodlands and Baan Phu Thara covers the Woodlands villas sold on leased land, HV316 among them.
