Foreign Property Ownership in Thailand: What Changed in 2026 and What It Means for Expat Buyers

If you've been thinking about buying property in Thailand, you've probably heard the rumours: "foreigners can buy land now," "the 30-year lease is dead," "the condo quota is going up." Most of those headlines are half-true at best. But underneath the noise, 2025 and 2026 brought some genuinely significant changes to how foreigners can own, lease and invest in Thai property.

We've broken down what actually changed, what didn't, and what it all means for you as an expat buyer.

Key takeaways

Nominee structures are under unprecedented scrutiny. Thailand's government launched a crackdown on tens of thousands of suspected nominee companies in 2025, and enforcement has only intensified in 2026.

"30+30+30" lease renewals are no longer legally reliable. A 2025 Supreme Court ruling found that pre-agreed renewal clauses beyond the initial 30-year term are not binding.

The 99-year leasehold proposal is still just a proposal. It has not been enacted, so don't make financial plans based on it passing soon.

The 49% condo foreign quota is unchanged. Proposals to raise it to 75% stalled. Enforcement is tighter, though, with a new digital tracking system.

New OCPB rules protect off-plan condo buyers. Stricter rules on deposits and reservations took effect in January 2025.

The 40 million baht land investment proposal is in limbo. The Cabinet endorsed it, but the National Assembly sent it back for review in early 2026.

1. The nominee company crackdown: the biggest shift

This is the change that matters most for expats who already own property through a Thai company, or who are being advised to set one up.

For years, a common workaround for Thailand's ban on foreign land ownership was the "nominee structure": a Thai-registered company in which Thai nationals held the majority 51% shareholding on paper, while the foreign buyer effectively controlled the company and the land it owned. In practice, the Thai shareholders were often nominees, people lending their names without any real financial interest in the company.

In May 2025, the Deputy Commerce Minister revealed that authorities had identified over 46,000 suspected nominee companies. The government launched a multi-agency enforcement drive combining the Department of Business Development (DBD), the Land Department and the Revenue Department, with AI-driven screening of company registries and property records.

What this means in practice: if you are considering buying land, including a house or villa, through a Thai company, the risk is now substantially higher than in years past. Authorities have the tools to detect nominee arrangements, and the consequences can include confiscation of the property, fines and criminal penalties. Relying on a 51% Thai shareholding alone is no longer a safe assumption.

The legal alternatives remain the safer paths: registered leaseholds, superficies rights and condominium ownership. If you already hold property through a company structure, we strongly recommend having it reviewed by a qualified lawyer to confirm it is compliant.

2. The Supreme Court ruling on 30-year leases

Leasehold has long been the main legal structure for foreigners who want to live in a house or villa in Thailand without owning the land. Under the Civil and Commercial Code, the maximum enforceable lease term is 30 years.

The problem was the "30+30+30" structure. Many developers and agents marketed leases with pre-agreed renewal clauses, two more 30-year terms stacked on top of the first, supposedly giving 90 years of security. These renewals were always legally uncertain.

In March 2025, the Thai Supreme Court settled the matter: pre-agreed renewal options beyond the initial 30-year term are not legally binding. Each renewal needs a fresh agreement between both parties at the time, with no guarantee that the landowner will agree.

What this means in practice: a 30-year registered lease is still a solid, enforceable right for its full term. Any renewal beyond that is not guaranteed, whatever your contract says. If a developer or agent is marketing a "90-year lease," treat the claim with serious caution: the first 30 years are enforceable, the next 60 are not. That makes it all the more important to negotiate good terms for the first 30 years and to understand exactly what happens when the term ends.

3. The 99-year leasehold proposal: promising but not law

In response to the Supreme Court ruling and the wider need for long-term investment security, the Thai government began exploring a 99-year leasehold scheme in 2025. Under the proposed framework, leases of up to 99 years would be available for non-agricultural land (residential, commercial and industrial). Lessees could mortgage, transfer or inherit the lease during its term, and the land would go back to the original owner, or the state, at the end of the 99 years.

This would be one of the most significant property law reforms in decades, if it passes. As of 2026 it remains a proposal. It has not been enacted into law, and there is no confirmed timeline.

4. Condo ownership: the 49% quota holds, but enforcement tightens

The condominium remains the most straightforward way for a foreigner to own property in Thailand outright: freehold, in your own name, with a chanote title.

The rule is simple. Foreign ownership in any single condominium building is capped at 49% of the total unit area. This has not changed. Early proposals to raise the cap to 75% stalled in committee and have not progressed.

What did change in 2026 is enforcement. The Land Department introduced a stricter digital tracking system that monitors foreign ownership ratios in real time and automatically flags buildings approaching the 49% quota. Before, tracking was less rigorous, and in some popular expat areas the numbers were not always tightly policed.

What this means in practice: if you're buying into a popular building, especially along the Sukhumvit line or in places like Phuket or Chiang Mai, check the foreign quota status early. Transfers in buildings near the cap may now take one to three weeks longer while the Land Department confirms the unit won't push the building over 49%. And don't assume a unit will still be available to foreign buyers by the time you're ready to transfer: in tight buildings, quota slots can fill quickly.

5. New OCPB rules: better protection for off-plan condo buyers

Thailand's Office of the Consumer Protection Board (OCPB) introduced new rules for condominium reservations that took effect in January 2025. They tighten how developers can take deposits and reservation fees from buyers of off-plan, pre-construction units.

Key protections include stricter requirements on how reservation contracts must be structured, clearer rules on when and how deposits must be returned, and limits on developers' ability to keep deposits if the buyer withdraws within the reservation period.

6. The 40 million baht land investment proposal: still in limbo

In late 2025, the Cabinet endorsed a draft that would allow foreigners who invest at least 40 million baht in Thai government bonds or other approved assets to buy up to one rai (about 1,600 square metres) of residential land. It builds on an existing but rarely used provision, Section 96 bis of the Land Code.

The proposal generated significant excitement, and significant pushback. In March 2026, the National Assembly sent the draft back for further review, citing concerns from rural and nationalist constituencies. As of mid-2026 it remains under review, with no clear timeline.

What should expat buyers do now?

The landscape has shifted, but the fundamentals haven't. Here's our practical guidance.

Condo freehold remains the simplest and safest ownership path. Buy within the 49% quota, in your own name, with a clean title, and check the building's quota status early.

If you want a house or villa, use a registered 30-year lease. It gives you enforceable rights for 30 years. Don't rely on renewal clauses beyond that.

Avoid nominee company structures. The crackdown is real, the detection tools are sophisticated and the consequences are severe. If you already have a company structure, get it reviewed.

If you're buying off-plan, make sure your reservation contract meets the new OCPB standards. Your deposit is better protected than before, but only if the contract is properly drafted.

Don't plan around proposals that haven't passed. The 99-year lease and the 40 million baht land scheme are worth watching, not worth betting on.

Getting advice

Thailand's property rules for foreigners have tightened in important ways, but they've also become clearer. The nominee crackdown, the Supreme Court ruling on lease renewals and the new OCPB protections all push in the same direction: toward structures that are transparent, legally sound and properly registered. That's good news for expat buyers who want to invest with confidence.
