Sap-ing-sit (rights over leasehold assets): what it is, pros and cons

Last checked 6 October 2026 · 6 min read · English

Sap-ing-sit (ทรัพย์อิงสิทธิ) is a registered right over a property, created by the Rights over Leasehold Assets Act B.E. 2562 (2019). Think of it as a 30-year lease that behaves like an asset: you can sell it, leave it to your heirs and use it as security for a loan. For foreign buyers, it fills a gap that ordinary leases leave open.

How it works

Only the registered owner can create sap-ing-sit, by registering it at the Land Office. If the property is mortgaged, the lender must agree in writing. The Land Office issues a sap-ing-sit certificate (หนังสือรับรองทรัพย์อิงสิทธิ) in two copies, one for the owner and one for the holder. The right lasts up to 30 years. The Act has no automatic renewal: when the term ends, the property returns to the owner, and any new term needs a new registration.

During the term, the owner keeps ownership but cannot add new encumbrances without the holder's consent, or subdivide or merge the land. The holder may use the property, make improvements within the law and the building's rules, and deal with the right itself.

Advantages
  • A tradable asset: you can sell it before the term ends.
  • Your heirs inherit the remaining term.
  • Can be used as loan collateral.
  • You can sublet without asking each time.
  • Open to foreigners, outside the condo foreign quota.
Disadvantages
  • Ends after 30 years at most, with no automatic renewal.
  • Value falls as the remaining term shortens.
  • Only for chanote land, buildings on it and condo units.
  • Few projects use it, so resale demand is untested.
  • Registration costs and taxes can be higher than for a simple lease.

Costs

The Act caps the registration fee for creating the right at ฿20,000. Reported costs also include a certificate fee, a transfer fee of about 2% of the declared value when the right is sold, a 1% fee for registering a mortgage, and possibly stamp duty and taxes on the owner's payment. Sources differ, so ask the Land Office or your lawyer for the exact figures for your transaction.

Who it suits

Some visa agencies list a registered sap-ing-sit of ฿3 million or more as a route for the property long-stay visa. Rules for non-condo routes are still being clarified, so confirm before you rely on it.

Kathy's view: sap-ing-sit is one of the best tools Thai law offers foreigners who want a house, because it turns a lease into a real asset. But it is still new, few sellers offer it, and the clock still runs out at 30 years. Price it on the years you actually get, check the title and the owner carefully, and use your own lawyer to draft and register it.
