Sap-Ing-Sith vs a 30-year lease in Thailand: the honest comparison
If you are a foreigner buying a villa in Thailand, you will be offered one of three things: a 30-year lease, a 51/49 company, or a Sap-Ing-Sith right. All three are described as "as good as owning". They are not the same, and the differences only show up when you try to sell, borrow against the property, or pass it to your children.
Statute
Act B.E. 2562 (2019)
Registered at
Land Office, on the Chanote
Start with the one rule that never changes
Under the Thai Land Code a foreign individual cannot hold freehold title to land. Everything on the market is a way of holding something against land that a Thai person or Thai company owns. So the real question is not "do I own it" — it is "what exactly do I hold, and how strong is it".
A 30-year lease is a contract between two people
A lease (เช่า, chao) under Sections 537–571 of the Civil and Commercial Code is a personal right. It binds your landlord, and only your landlord. Leases over three years are annotated at the Land Office, but the instrument itself stays a contract. In practice that produces four soft spots:
—You usually cannot assign or sell the lease without the landlord's written consent, and consent can be refused or repriced.
—Inheritance is contested: Thai courts have repeatedly treated lease rights as personal and terminating on death.
—No bank will lend against it, because there is nothing on the title to secure.
—"30+30+30" renewals are promises, not rights. The Thai Supreme Court has declined to enforce them more than once.
Sap-Ing-Sith is a right on the deed
The Sap-Ing-Sith Act B.E. 2562 (2019) — the Property-Based Right Act — created a new registrable category of property right. It is inscribed directly on the Chanote at the Land Office, next to the freehold owner, and it attaches to the land rather than to the person who granted it. It is open to any natural or legal person, Thai or foreign, for a statutory term of up to 30 years.
Because it is a real right, it behaves like an asset: freely transferable without landlord consent, inheritable by statute for the remainder of the term, mortgageable including with Thai banks, and unaffected if the land changes hands. A new owner of the land takes the land with your right on it.

| Question | 30-year lease | Sap-Ing-Sith |
|---|
| What is it legally? | Personal contract | Registered property right |
| Can I sell it? | With consent | Freely |
| Do my children inherit it? | Contested | Yes, by statute |
| Can I borrow against it? | No | Yes |
| If the landowner sells? | At risk | Right stays on the title |
A lease gives you the use of a villa. A registered right gives you an asset. The gap between those two words is the entire decision.
What happens when a leaseholder tries to sell
This is where the theory becomes money. A buyer's Thai lawyer opens the lease and finds an assignment clause requiring the landlord's written consent. So the deal now has three parties. The landlord is entitled to say no, to take weeks to answer, or to name a price for saying yes — commonly a percentage of the sale. Meanwhile the buyer is being asked to pay today's market price for a contract with, say, nineteen years left on it, no renewal they can enforce, and no bank willing to fund it.
Most of those deals do not fail dramatically. They just drift: six months on the market, two price reductions, and a sale to a cash buyer at a discount that quietly wipes out several years of rental income. The lease was never defective — it simply was not built to be sold.
Read the contract
The three clauses that decide whether you own an asset
01Assignment. "The Lessee may transfer this lease with the prior written consent of the Lessor" means you cannot sell without permission. A registered right has no equivalent clause — consent is not required.
02Succession. Silence here is the danger. If the contract does not say the lease passes to your heirs, Thai courts have generally treated it as ending with the lessee.
03Renewal. "The Lessor shall grant a further term of 30 years" is a promise by one company to a future buyer of that company. Thai courts have declined to enforce renewals against a new landowner.
Where the two are genuinely equal
Honesty helps here. For day-to-day use they are the same: you live in the villa, you rent it out, you renovate it, you pay the same utilities and the same taxes. Both are capped at 30 years — Sap-Ing-Sith is not "longer ownership". Both sit on land owned by a Thai person or company. And both cost roughly the same at the Land Office. The difference is not the holiday; it is the exit.
What it costs at the Land Office
Registration involves a transfer fee (typically 2% of the registered value, by Thai custom split 50/50 between the parties), stamp duty of 0.5%, and a fixed Land Office fee for inscribing the right on the Chanote. These are government fees and sit outside any service fee. Registration itself normally completes in about two weeks from signing.
The practical answer
If you plan to use the villa for a few years and walk away, a lease is cheap and simple. If the property is meant to be an asset — something you can rent, borrow against, sell to someone else, and leave to your family — a lease gives you none of those with certainty, and a registered right gives you all four. That is the whole comparison.
Questions we get asked
Is Sap-Ing-Sith actually being registered, or is it still theory?
It is registered practice. The Act has been in force since 2019 and Land Offices process the inscription as a standard entry on the Chanote. The realistic constraint is not the law — it is finding a landowner willing to grant the right, which is exactly what United Grace exists to be.
Can I convert an existing lease into a Sap-Ing-Sith right?
Not by conversion. The land has to be acquired by a landowner who will grant the right, and the right is then registered fresh in your name. In practice that means an asset purchase — which is the route we run for owners who already hold a villa through a lease or a company.
What happens at the end of 30 years?
The right expires and the land remains with the owner. Two things matter in the meantime: you can sell the remaining term at any point, and the value of what you sell declines as the term shortens — which is an argument for holding it inside a network with ready buyers rather than alone.
Does a mortgage really work in practice?
The right is mortgageable as a matter of law, and Thai banks can register a mortgage over it. Whether a given bank lends to a given foreign borrower is a credit decision, not a legal one — but with a lease there is nothing to secure in the first place.
Is a 51/49 Thai company safer because I "control" it?
Control is the problem, not the reassurance. If Thai shareholders hold their shares on your behalf, the arrangement is a nominee structure and unlawful under the Land Code and the Foreign Business Act. A registered right needs no shareholders at all.
