Thailand's Lemon Law 2026: Why It Won't Protect Condo Buyers

A studio owner in Jomtien accepts handover of his new unit, switches on the air conditioner, and twenty minutes later there is a puddle on the laminate floor. The developer nods, promises to send a repair team, and shows up six weeks later. The owner reads news about Thailand's new 'Lemon Law' and assumes he can now demand a full refund on his condo.

He cannot. The Liability for Defective Goods Act, approved by Thailand's Cabinet on 16 June 2026, covers goods such as cars, motorcycles, appliances, and electronics. Real estate is excluded. The bill has only moved on to Parliament, meaning it was not yet in force at the time of writing. In fact, Bangkok Post reported that Thai MPs backed the landmark bill only in principle, shifting the burden of proof for defects from buyers to sellers, a step still working its way through the legislative process.

Condo buyers do have another, less publicized toolkit: the developer's statutory warranty under the Condominium Act, and the Office of the Consumer Protection Board (OCPB) rules that, since 2025, cover condo reservation contracts and long-term residential leases.

Quick Answer

• On 16 June 2026, Thailand's Cabinet approved the draft Liability for Defective Goods Act, which then moved to Parliament; the effective date depends on the parliamentary process.

• The law presumes a defect existed from the start for 6 months on standard goods and 1 year on vehicles, with the burden of proof shifted to the seller.

• The law does not apply to used goods, animals, private person-to-person sales, or real estate.

• New condominium units are covered instead by the standard Condominium Act B.E. 2522 sale contract: 5 years on structural elements and 2 years on other building and unit components, counted from the date of title transfer registration, with written notice required within that window.

• OCPB rules ban unjustified deposit retention, unfair limits on developer liability, and penalty fees for resale/assignment in regulated contracts; serious breaches let the buyer cancel and reclaim payments plus interest.

Scenarios and Options

Handover of a new-build unit. This is the most common scenario, and the only moment when a buyer holds real leverage over the developer. Before signing the handover form and making the final payment, you set the terms; after registration at the Land Department, you are asking for favors. Do not schedule the Land Office transfer until the defect list is closed in writing. If the handover coincides with a trip to Thailand, build in an extra week to ten days, since a second inspection after repairs is almost always necessary.

Resale from a private owner. Neither the Lemon Law nor the developer's warranty applies here. You are left with the general hidden-defects provisions of the Civil and Commercial Code, under which a claim must typically be filed within one year of discovery. The burden of proof falls on you, and by then the seller may already be living in another country.

Long-term rental. OCPB's rules for regulated residential leasing target the most common pain point: arbitrary deposit withholding. Landlords must return the deposit unless they can prove damage beyond normal wear and tear. This only works with a written contract, a condition inventory, and move-in photos.

Furniture and appliances inside the unit. This is exactly where the future Lemon Law will help. Air conditioners, built-in kitchens, and TVs bought from a corporate seller will fall under the six-month defect presumption. Keep receipts and warranty cards in the same name as the unit contract, and hold onto them until the warranty expires.

Main Risks and Mistakes

Signing the handover form without a defect list. Thai developers often present a form stating the buyer accepted the unit without complaints. Mitigation: handwrite every defect with photos and dates, and keep a copy signed by the developer's representative.

Staying silent during the warranty period. The two-year and five-year Condominium Act warranties do not renew automatically. Mitigation: send written notice to the developer with the delivery date, not a message to a sales manager on WhatsApp or Line.

Assuming the Lemon Law will cover your condo. The bill is built entirely around goods, and real estate is not mentioned. Mitigation: stop citing it in developer negotiations; the Condominium Act warranty argument is far stronger.

A reservation contract in English with no Thai version. If the texts diverge, the Thai version prevails in court. Mitigation: use a bilingual document that states which version takes priority, and have a lawyer review it before transferring any deposit.

An assignment penalty clause buried in the contract. OCPB has banned such terms in regulated contracts, but they still appear in paperwork from smaller developers. Mitigation: strike the clause before signing, or if already signed, cite the OCPB rules and file a complaint with the Office.

Endless repair cycles. The developer technically responds, shows up, repairs poorly, and returns again. Mitigation: set a firm deadline in writing and negotiate the right to hire an independent contractor with cost reimbursement.

FAQ

Does Thailand's Lemon Law apply to buying a condo?

No. The Liability for Defective Goods Act governs goods, primarily cars, motorcycles, and consumer electronics. Condominiums are excluded.

When will the new law take effect?

Thailand's Cabinet approved the draft on 16 June 2026 and sent it to Parliament. The effective date depends on how the readings proceed, and no exact timeline can be given yet.

What warranty applies to a new condominium in Thailand?

Under the standard sale contract required by the Condominium Act B.E. 2522: five years on structural elements and two years on other components, counted from title transfer registration. Claims must be filed within that window.

Can I get my condo reservation deposit back?

Yes, if the developer breaches the terms or the contract includes clauses banned by OCPB. For serious violations, buyers can cancel the contract and recover all payments plus interest.

Does the law protect buyers of resale properties?

The Lemon Law does not apply to used goods or private person-to-person sales. Resale property buyers rely instead on the Civil and Commercial Code's hidden-defect provisions, with a one-year window from discovery.

Where can I file a complaint against a developer in Thailand?

The Office of the Consumer Protection Board (OCPB), where real estate is among the most common complaint categories. A parallel civil claim is also possible, and for amounts under one million baht this is often cheaper than expected.

What should I do if defects appear after title registration?

Send the developer written notice with photos and the discovery date, citing the warranty period in the contract. Do not raise the issue only verbally; six months later you will have nothing to prove it happened.

Should I hire an inspector for the handover?

For budgets from 4-5 million baht, yes: an independent inspection costs roughly 10,000-20,000 baht for a studio or one-bedroom unit and typically finds defects buyers would otherwise miss. For a 1.8 million baht studio, the cost is more debatable; a careful walkthrough with a checklist is usually sufficient.
