A legal guide to Thailand’s "Sale with Right of Redemption"—how it compares to mortgages, key legal frameworks, benefits, risks, and expert advice.
Kaifak (ขายฝาก — pronounced khai-fak) is legally defined as a "Sale with Right of Redemption" under Sections 491 to 502 of the Thai Civil and Commercial Code (CCC), reinforced by the Protection of People in Sales with Right of Redemption Act B.E. 2562 (2019).
Ownership of the property legally transfers to the buyer (investor/lender) on day one at the Land Office.
The seller retains the legal right to buy back the property within a contractually agreed timeframe by paying back principal plus agreed profit/interest.
If the seller fails to redeem before the legal deadline, full, unencumbered ownership permanently stays with the buyer without needing a court foreclosure.
Entities and individuals permitted under Thai law to act as Kaifak buyers/lenders
High-net-worth private investors seeking secure asset-backed returns capped at 15% per annum.
Licensed private liquidity firms and asset management businesses operating under Thai commercial regulations.
Professional agencies (such as RE/MAX) that connect property owners with verified legal buyers.
Foreigners can fund Kaifak contracts. However, for land default, they must operate via legal entities or stick to eligible condo units.
Key contractual elements required by the Thai Civil Code and the 2019 Protection Act
The contract must explicitly state the initial sale price (principal) and the exact redemption price (principal + agreed interest return, max 15% p.a.).
Specific end date for redemption. Housing & agricultural land require a statutory minimum of 1 year, up to a maximum cap of 10 years.
The agreement must specify whether the seller retains the right to occupy or rent out the property during the contract term and under what conditions.
Clear allocation of Land Office transfer taxes, property maintenance duties, insurance, and land tax obligations between seller and buyer.
Critical legal protection rules under the 2019 Protection of Kaifak Act
Never rely on unrecorded contracts, private promissory notes, or messaging app promises. Under Thai law, only terms formally endorsed on the back of the Title Deed (Chanote) at the official Land Office are legally binding.
Under the 2019 Act, the buyer (lender) is legally obligated to deliver a formal written notice to the seller between 30 and 60 days before the contract expires, specifying the redemption amount and deadline. If the buyer fails to notify, the law automatically extends the redemption period by an additional 6 months.
If a predatory buyer tries to avoid receiving payment when you are ready to redeem, you can legally deposit the redemption funds at the Legal Execution Department (LED) or local Land Office before the deadline to legally preserve ownership.
Kaifak (ขายฝาก) vs. Traditional Mortgage (จำนอง)
| Feature | Kaifak (ขายฝาก) | Standard Mortgage (จำนอง) |
|---|---|---|
| Title Ownership | Buyer (Investor) immediately | Borrower (Remains on Title) |
| Legal Term Cap | Up to 10 Years (Min. 1 year for housing) | Flexible (Up to 30 Years) |
| Interest Cap | Max 15% per annum by Thai law | Varies (Bank rates ~3%-8%) |
| Approval Speed | Very Fast (2 – 5 days) | Slower (3 – 8 weeks) |
| Income / Credit Check | No credit check required | Strict financial checks required |
| Land Office Fee | Higher (Transfer 2% + WHT + SBT/Stamp) | Lower (Mortgage registration fee 1%) |
"Never rely on verbal agreements or informal LINE messages with the investor to extend your redemption period. Under Thai law, any extension of a Kaifak agreement **must be formally recorded on the back of the official Title Deed (NS-4J / Chanote) at the Land Office before the contract expires**. If you fail to register it legally before midnight on the final day, the buyer becomes the permanent 100% legal owner, and informal promises cannot be enforced in court."
Yes, as investors/lenders. Foreigners can act as the buyer in Kaifak contracts to earn interest returns. However, because foreign nationals cannot directly own land in Thailand, if the seller defaults on land, foreign buyers cannot legally retain sole title to the land without proper legal structuring. Foreigners can, however, use Kaifak for condominium units within foreign ownership quotas.
The legal ceiling for Kaifak interest/profit is strictly capped at 15% per annum above the actual registered sale price. Under the 2019 Act, any contractual clause stipulating interest exceeding 15% per year is automatically voided and reduced to the statutory maximum.
The right of redemption automatically lapses. Full, unencumbered legal title permanently consolidates with the buyer without court intervention. However, under the 2019 Protection Act, the buyer must send a formal written notice to the seller at least 30 to 60 days before expiration informing them of their redemption rights.
Yes. Both parties can agree to extend the contract term, provided the total cumulative period does not exceed 10 years for real estate. Crucially, this extension must be registered at the Land Office before the current term expires.
While the law allows parties to negotiate fee splits freely, standard practice usually assigns government transfer fees (2%), withholding tax, and specific business tax/stamp duty to the seller or split 50/50. When the seller redeems the property back, transfer fees are assessed again upon re-registration.
