Direct answer

After transfer, buyers rely on a mix of contract warranties, developer after-sales policies, and—where applicable—legal doctrines on hidden defects. Exact liability periods and remedies are document- and fact-specific; this guide does not invent statutory deadlines. Photograph snags, give written notice on time, and keep counsel involved when the seller or developer disputes coverage.

Key takeaways

  1. 1.Read SPA warranty clauses before you celebrate handover keys.
  2. 2.Separate cosmetic snagging from structural or waterproofing failures.
  3. 3.Send dated written notices; verbal lobby chats are weak evidence.
  4. 4.Latent issues may surface later—preserve inspection records from day one.

Important terms

Defect liability / warranty period — A contractual window (sometimes reinforced by law) during which the seller/developer must remedy defined defects. Length and scope vary by contract.

Latent defect — A problem not reasonably discoverable at handover with ordinary inspection.

Snagging list — Itemized punch list created at inspection, ideally with photos and deadlines.

Notice — Formal written communication required to trigger many remedies.

Detailed answer

Layer the sources of rights

Buyers often hear “one-year warranty” without reading exclusions. Diligence means reviewing: SPA clauses, any separate warranty booklet, common-area vs unit responsibilities, and juristic-person rules after condo handover. Registration at the Department of Lands transfers title; it does not by itself write your warranty terms.

Inspection quality

Cosmetic lists miss waterproofing, slope-to-drain, electrical load, and movement cracks. Consider an independent inspector or engineer for high-value assets (see related structural-snagging guidance).

After notice

Track acknowledgment, access appointments, and whether “repairs” are temporary patches. Escalate per SPA dispute clauses rather than endless informal chats.

Step-by-step

  1. Before transfer, obtain warranty schedules in Thai and English with parity check.
  2. Conduct handover inspection with camera and moisture meter if appropriate.
  3. Deliver a signed snag list the same day when possible.
  4. Diary every contractual notice deadline.
  5. For post-handover discoveries, document with dates and expert notes.
  6. If refused, instruct counsel early—while evidence is fresh.

Hypothetical example (clearly labeled)

Hypothetical: Two months after transfer, a buyer finds staining under a balcony door. Photos, a humidity reading, and written notice go to the developer within the SPA window. A patch without membrane work is rejected; the buyer requests membrane remediation per warranty scope.

Illustrative only—not a guarantee of coverage.

Risks

  • Missing notice periods while traveling.
  • Accepting cash “goodwill” that waives broader claims without counsel.
  • Common-area leaks mis-assigned solely to your unit.
  • No baseline photos, making causation fights harder.

Practical checklist

  • Warranty clauses extracted
  • Handover photo set archived
  • Snag list delivered and acknowledged
  • Notice deadlines calendared
  • Expert retained for non-cosmetic issues
  • Counsel ready if denial letters arrive

FAQ

Does Thai law always give me two years on latent defects?

Do not rely on blog numbers. Ask counsel to apply current instruments to your facts.

Are second-hand resales warranted like new builds?

Often weaker or seller-specific. Negotiate expressly.
