Direct answer
An official Thai government portal states that under the Condominium Act 1979 foreigners may own within a 49% limit and should request a letter confirming the foreign proportion from the condominium juristic person for Department of Lands transfer. The English portal wording refers to 49% of the total number of units; whether controlling Thai law measures units or saleable area must be confirmed with counsel. Do not rely on sales-gallery verbal assurances alone.
Key takeaways
- 1.Official portal guidance: foreigners may own within a 49% limit under the Condominium Act 1979.
- 2.Request a foreign-proportion letter from the condominium juristic person for Land Office transfer.
- 3.English portal wording emphasises units—flag possible area-based measurement in Thai law.
- 4.Quota is a building-level fact that can change as units transfer.
- 5.Needs Thai legal review before transactional reliance.
Important terms
49% foreign limit — The foreign-ownership ceiling summarised on THAILAND.GO.TH for condominiums under the Condominium Act 1979. (thailand-go-condo)
Foreign-proportion letter — Letter from the condominium juristic person confirming the foreign proportion for Department of Lands transfer, as described on the same portal.
REIC — Real Estate Information Center; the portal note includes REIC contact attribution. (reic-home)
Detailed answer: what the official portal establishes
The official English issue note establishes three operational points buyers can verify:
- Foreigners may own within a 49% limit under the Condominium Act 1979.
- The buyer should request a letter confirming the foreign proportion from the juristic person.
- That letter is used in the Department of Lands transfer process.
How to verify capacity (practical method)
Step-by-step
- Identify the exact condominium juristic person for the building.
- Request a current foreign-proportion letter stating remaining foreign capacity in the form the Land Office expects.
- Ask counsel to read the letter against the Thai statutory measurement method.
- Re-check close to transfer day—quota can change when other foreign transfers complete.
- Do not accept only a sales agent’s verbal “still available” statement.
Comparison table
| Evidence | Useful for | Weakness if used alone |
|---|---|---|
| Juristic foreign-proportion letter | Land Office transfer gate described on official portal | Must be current and correctly calculated |
| Sales gallery spreadsheet | Conversation starter | Not a substitute for the juristic letter |
| Older SPA annex | Historical context | May be stale |
| Blog percentage calculators | None for closing | Often invent methodology |
Hypothetical example
Assumed facts: A project markets “40% foreign sold.” A buyer deposits without a juristic letter. At transfer, the letter shows foreign capacity is exhausted under the method the Land Office applies.
Lesson: Building marketing percentages are not the same as a current juristic letter used for transfer.
Risks
- Using unit-count math when the Land Office applies a different statutory method—or the reverse.
- Relying on stale letters issued months earlier.
- Confusing leasehold foreign holdings with freehold quota (ask counsel how your building accounts for each).
Checklist
- Current juristic foreign-proportion letter obtained
- Counsel confirms measurement method against Thai Condominium Act text
- Letter dated close to the intended transfer
- SPA addresses failure if quota blocks foreign freehold transfer
- No reliance on verbal quota assurances alone
FAQ
Is the 49% rule national?
The Condominium Act framework summarised on the official portal is national; capacity is checked building by building.
Who issues the verification letter?
The condominium juristic person, per the official portal description for Department of Lands transfer.
Can REIC tell me a building’s remaining quota?
REIC publishes market information more broadly. Building-level quota evidence for transfer still runs through the juristic person and Land Office process described on the portal.
