Sap Ing Sith in Phuket: 30-Year Right for Foreigners

Sap Ing Sith is a registered real right, created by Thailand's Sap Ing Sith Act B.E. 2562 (2019), that lets a holder use land, a house or a condominium unit for up to 30 years and sell, mortgage or bequeath that right without the owner's permission. Because the land stays with its Thai owner, foreigners can hold it, which is why Phuket developers and lawyers are now discussing it as a lawful alternative to the nominee structures that authorities are investigating.

What is Sap Ing Sith and why is Phuket talking about it?

Phuket's villa market sits under heavier scrutiny than at any time in recent years. The Nation reported on 4 November 2026 that nominee investigations, including a Department of Special Investigation arrest linked to a luxury villa rental business, are complicating the island's property boom. In an earlier Nation interview, Phuket Real Estate Association president Maetapong Upatising said stricter nominee checks had hit luxury pool villas harder than condominiums, and described "registered property-use rights" of up to 30 years, without a transfer of freehold land, as an increasingly discussed option for foreign villa buyers. That description matches the framework.

He also noted awareness is still limited, particularly among Russian buyers, while Chinese buyers appeared more receptive because they saw a clear legal basis.

How does the registered right work in practice?

According to the text of the Act as published by ThaiLawOnline, only the registered owner can create the right, and only over land with a full chanote title, that land together with its buildings, or a condominium unit. The main rules are:

• Term: up to 30 years, with no automatic renewal (Section 4). Continuing requires a new agreement and fresh registration.
• Whole title only: it cannot cover part of a title deed or unit.
• Existing charges: a mortgaged property needs the lender's written consent.
• Registration: the Land Office records it on the deed and issues a certificate for the right in two copies (Section 5).
• Transferable: the holder can sell, mortgage or pass it to heirs; every such act must be in writing and registered (Section 12).
• Limits: the holder acts much like an owner, but legal actions to recover the property remain with the owner (Section 11).

Lawyers also point out that holding the right does not change business rules: DanSiam, citing the Dharmniti Law Office, notes any business use by a foreigner still falls under the Foreign Business Act. That matters for anyone planning nightly villa rentals; see our guide on whether Airbnb is legal in Phuket.

A registered right vs a 30-year lease: which is stronger?

Most foreign villa buyers in Phuket still sign registered 30-year leases. Sansiri's new The Tales Story Two Pasak villas, priced from 49.5 million baht, are sold on 30-year leasehold contracts, the Bangkok Post reported this week. The difference is mainly what happens to the right after signing. Our freehold vs leasehold Phuket guide covers lease renewal risk in detail; the summary below shows where this right differs.

Neither route gives a foreigner land ownership. Land Code section 86 still bars it, as Phuket law firm Lex Estate summarises; the two other registered rights it lists are usufruct and superficies. For condos, freehold ownership within the 49% foreign quota remains the simplest option.

What does registration cost?

Land Office fees come from a 2020 ministerial regulation. Figures published by DanSiam and ThaiLawOnline are:

• Creating and registering the right: 20,000 baht
• Issuing the certificate: 10,000 baht
• Transfer for value: 2% of the declared value
• Transfer without payment (gift or inheritance): 1,000 baht
• Registering a mortgage over the right: 1% of the secured sum

DanSiam found no Revenue Department ruling on how transfers are taxed, and secondary sources disagree, so get a Thai tax adviser's view before agreeing a price. Compare these with the costs of a normal sale in our Phuket property transfer fees breakdown, and remember that money coming from abroad should be documented, as explained in our FET form guide.

Is this right for your Phuket purchase?

It suits buyers who want a tradeable, inheritable right to a villa or house for a fixed period, and who value a Land Office certificate over a private contract. It is less useful where the price only makes sense with renewals beyond 30 years, because the Act offers none. Run the numbers on a 30-year horizon using realistic rents; our Phuket condo rental yields and Phuket villa prices guides give current ranges. Buyers who also want long residence can look at the LTR visa, which developers are pairing with property sales.

FAQ

Can a foreigner hold this right in Phuket?

Yes. The Act sets no nationality limit on holders, and because the Thai owner keeps the land, the foreign land ban is not triggered.

Does it work on any land title?

No. It needs a chanote title or a condominium unit title, and it must cover the whole title.

Can the owner cancel my right early?

Not at will. The right is registered and can be sold or inherited without the owner's consent, but the contract terms still matter, so have a lawyer draft them.

Is this legal advice?

No. This is a newsroom summary of the Act and published guidance. Check the title deed and terms with an independent Thai lawyer before you sign.
