Year 30 of a Thai Lease: Can You Renew, and What Happens If You Cannot?

30-Year Lease Renewal in Thailand: What Happens at Year 30?

Many of the buyers I meet ask whether the law on owning property in Thailand has changed. My answer is that it has not. It is being enforced now in a way it was not before, as our piece on the nominee company crackdown explains. The next question is nearly always about long leases: “So what happens after 30 years?” I tell them what I know: after 30 years, an extension is not guaranteed. It has to be agreed with the landowner. Beyond that, I always send them to a Thai lawyer to look at their own lease, because the wording matters.

This guide sets out what the law says about year 30, so that conversation can start from facts. It is general information about Thai law as we understand it, not advice on your own lease.

Can you renew a 30-year lease in Thailand?

Section 540 of the Civil and Commercial Code limits a lease of immovable property to 30 years, and a longer term is cut back to 30. Renewal is allowed, but each renewal term is also capped at 30 years, counted from the date of renewal.

What the law does not give is a right to renew. When the lease ends, a new lease has to be agreed with the landowner, and the landowner is free to say no or to change the terms. We are not aware of any Thai statute that lets a tenant demand an extension, and we recommend your lawyer confirms this against your own lease.

Two practical points sit alongside this. A lease of more than three years has to be in writing and registered at the Land Office; if it is not registered, only three years can be enforced. And the 50-year terms you may read about come from a 1999 Act for qualifying commercial and industrial use, which does not cover a private home.

Here is how that plays out. Say a lease is registered in 2026. It runs to 2056, and any extension would be agreed in 2056, with the new term counted from that date and capped at 30 years. Nothing signed today can fix the terms of that later negotiation.

What did the Supreme Court decide about 30+30+30 leases?

The case concerned Phuket land leased in 1990. The lease carried two further 30-year terms, agreed and signed in advance. When the tenant refused to leave at the end of the first term in 2020, the court ordered the tenant out.

The reasoning is that renewal terms agreed on day one are a way of getting around the 30-year limit. The first registered term can stand. The promised extensions cannot be enforced.

That does not make a leasehold the wrong choice for everyone. It means the extra years are not something you own, and a fair price reflects only the years you can rely on.

When a lease mentions renewal, ask your lawyer whether it describes a future agreement to be made at the time, or tries to promise renewal today. The first can be negotiated. The second is the pattern the court rejected.

What happens to the value of a leasehold as the term runs down?

Think in remaining years, not headline years. A villa on a 30-year lease with 28 years left and the same villa with 12 years left are different assets to a later buyer, even if the house looks identical.

We have observed that buyers ask about the long lease early in the conversation. Because an advance renewal promise cannot be enforced, the safest way to look at a leasehold is on the registered term alone, with any renewal treated as a possible bonus rather than part of what you are paying for.

If you plan to sell the leasehold later, ask your lawyer how the transfer of a lease works and what a buyer will want to see. A buyer will want the registered lease and its remaining term in front of them.

Who will own the land in year 30?

Renewal is a conversation with the person who owns the land in year 30, and that may not be the person who signed your lease. The landowner may have sold, or the land may have passed to heirs.

A registered lease survives a sale of the land under Section 569, so the new owner takes the land subject to your lease for its remaining term. A promise of renewal made by the old owner is a different matter, and it may not bind a buyer or heirs. Your lawyer can tell you how this applies to your lease.

What can you do now to protect a leasehold?

Ask the landowner about their intentions well before the last years of the lease, and keep a record of what is said, knowing that a conversation is not a legal right. Early clarity is better than a surprise in year 29.

Other structures exist, and each carries its own conditions: a superficies, a usufruct, or a condominium unit held freehold within the foreign ownership quota. We name them so you know the questions to ask, not to recommend one. Our guides on foreign property ownership and buying a villa in Chiang Mai set out the main routes.

Questions worth putting to your lawyer: When was the lease registered, and how many years remain? Who owns the land, and what is the title history? What does the lease say about renewal, and does it describe a future agreement or promise one today? What happens if the landowner sells or dies? What would you do differently if you were buying the same property as a freehold unit?

Why do 30-year leases matter in 2026?

The Phuket case shows the pattern: a lease from 1990, a renewal the tenant expected, and a landowner who said no. Any lease signed in the late 1990s ends in the late 2020s, so more owners will face the same question.

In our experience, enforcement of Thai property rules is tighter than it used to be, and the nominee company crackdown covered in our earlier piece is one example. For the wider picture, see our guide to buying property in Chiang Mai.
