What leasehold actually is
Leasehold in Thailand is a registered right to occupy and use land or a building for a fixed term. It is created by a written lease that is registered at the Land Office and endorsed on the back of the title deed. Once registered, the lease is a real property right - it binds any future owner of the land, not just the person you signed with. That single fact is what separates a registered lease from a private rental agreement.
For a foreign buyer who cannot own land directly, a properly registered lease is the honest and enforceable way to secure a house or villa long-term. It is not freehold and no one should pretend otherwise, but it is a legitimate structure recognised by Thai law and used every day by ordinary Thai families as well as foreign residents.
The 30-year limit under Civil and Commercial Code Section 540
Civil and Commercial Code Section 540 caps the registered term of a lease at 30 years. A lease document that states 60 or 90 years is not enforceable beyond 30 years - the Land Office will simply register the first 30. Any additional term must come from a fresh registration made at that later date. This is a hard statutory limit and no contract clause can override it.
Because the initial term is capped, the market has settled on a common structure: a registered 30-year lease with contractual options to renew for one or two further 30-year terms. The renewal options are real promises between the parties, but they are not automatic real rights - see the next section.
Renewal options: what they are and are not
A renewal option in a lease is a contractual promise by the landowner to grant a new lease at the end of the current term. It is enforceable against the original landowner as a matter of contract law. If the landowner refuses to sign, the tenant can sue for breach and, in principle, obtain specific performance or damages.
What a renewal option is not: an automatic extension that binds future owners of the land. If the land is sold during the first 30 years, the buyer takes the land subject to the registered lease, but not automatically subject to unregistered renewal promises. This is why serious leasehold structures pair the renewal option with additional protections - a right of first refusal, a mortgage over the land in favour of the tenant, or a superficies right registered alongside the lease.
Registration: the step that actually protects you
A lease of more than three years must be registered at the Land Office to be enforceable for its full term. The registration is what turns the paper contract into a real property right. Without registration, a long lease is treated as a three-year tenancy and everything beyond three years is unenforceable.
Registration costs are modest: a fee of 1 percent of the total rent for the whole term, plus stamp duty of 0.1 percent. On a 30-year lease with a nominal annual rent, this is a small one-off cost. The Land Office endorses the lease on the back of the title deed, which is the visible proof that the right exists and survives any later sale of the land.
Sub-lease, assignment, and inheritance
By default, a registered lease is personal to the tenant: it cannot be sub-let, assigned to a third party, or automatically inherited on death. Each of these has to be expressly permitted in the lease itself. A well-drafted lease for a foreign buyer will include the right to assign, the right to sub-lease, and a clause allowing the lease to pass to named heirs. Without these clauses, the lease can end on the tenant's death and the family loses the home.
These are not exotic requirements. They are standard clauses in leases used for expat homes across Cha-am, Hua Hin, Phuket, and Bangkok. A qualified Thai lawyer will insist on them, and any developer selling leasehold villas to foreign buyers should already have them in the template.
Leasehold as the alternative to a nominee company
The reason leasehold matters more now than five years ago is the 2025-2026 enforcement wave against nominee land-holding companies (see our nominee crackdown guide). Where a Thai company with 51 percent Thai nominee shareholders used to be sold as a way for foreigners to "own" a house, that route is now actively investigated under IBAS and Order No. 2/2568, with forced sale under Land Code Section 94.
A registered 30-year lease is the honest alternative. It is smaller than freehold, but it is a real right recognised by Thai law, it is enforceable against successors, and it does not depend on a fiction about who paid for the shares. For most foreign buyers looking at houses in Cha-am, it is the right structure. For condominiums, the freehold route is available inside the foreign quota - see the condo foreign quota guide.
What to check before you sign
Before signing any leasehold contract, verify five things with an independent lawyer: that the land title is clean and the landowner has the right to lease; that the lease will actually be registered at the Land Office and not just kept as a private document; that assignment, sub-lease, and inheritance rights are expressly included; that the renewal option is backed by realistic security, not just a promise on paper; and that the developer or landowner is not simultaneously offering a nominee company structure as an "upgrade" - that is a warning sign, not a benefit.
