Condo handover in Thailand: the snagging inspection, the defect list, and not paying for a half-finished unit

Handover day is your one real chance to catch a new-build condo's construction defects while the developer is still on the hook to fix them. This guide walks what handover actually involves, the room-by-room defect (snagging) checklist, whether to hire a professional inspector, how the defect list and re-inspection work, your right to hold back the final payment until snags are fixed, and the warranty that covers you after you move in. Unbiased, never paid placement.

The one-line version

Handover is your leverage moment — inspect before you accept. Walk the finished unit, test every fixture, and write down every defect (the snag list) while the developer is still obliged to fix them for free. Consider a professional inspector, keep the final payment as leverage where your contract allows, re-inspect that snags were actually fixed, and lean on the statutory warranty for anything that surfaces after move-in.

01

What handover actually is — and why it's your leverage moment

Handover — sometimes called the transfer or acceptance inspection — is the appointment where the developer formally hands you the finished unit and you check it against the contract before you accept it and pay the final balance. For a new-build condo bought off-plan, this is the single most important day of the whole purchase after signing, because it is your one real window to catch construction defects while the developer is still contractually obliged to remedy them at their own cost. Once you sign final acceptance and the money has moved, your position shifts from "fix this before I pay" to "please honour the warranty" — a much weaker spot. Treat handover as an inspection, not a celebration: bring a checklist, leave the champagne for later.

02

The room-by-room defect (snagging) checklist

Work methodically through the unit and test everything that moves, opens, drains or powers on. Photograph every defect and note its exact location:

What to check, system by system
  • Floors & walls — level surfaces, no cracks, no hollow-sounding tiles (tap them), even paint and clean grout lines
  • Doors & windows — proper alignment, locks that work, seals intact, runners and hinges smooth, no gaps
  • Plumbing — water pressure, no leaks under sinks, fast drainage, toilet flush, and no sewer smell from traps
  • Electrics — every socket and switch, the consumer unit/breakers, and all light fittings working
  • Air conditioning — each unit cools properly, drains correctly and doesn't drip water inside
  • Kitchen & bathroom — fittings secure, sealant neat, no chips or cracks, extractor and exhaust working
  • Ceilings — no water stains or sagging (a sign of leaks from the unit above or the roof)
  • Balcony — drainage falls the right way, railing height and fixings safe, waterproofing intact
  • Spec match — every promised appliance, wardrobe, fixture and finish is actually installed and undamaged

Cross-check the installed fittings against the specification schedule in your contract — a downgraded material or missing appliance is a contractual breach, not just a snag. If you're buying rather than renting, this pairs with the pre-purchase due-diligence checklist.

03

Should you hire a professional snagging inspector?

For a new-build condo, usually yes. Professional inspection companies operate in Bangkok and the main cities and bring tools an ordinary buyer doesn't have — moisture meters, thermal cameras, laser levels and electrical testers — plus a trained eye for the defects developers most often leave behind: hollow tiles, hidden leaks, poor balcony and bathroom waterproofing, and substandard electrical work. They produce a detailed, photographic defect report that developers take seriously, and their fee is modest against the price of the unit. A good inspector routinely finds problems you'd never spot. If you choose to inspect yourself, go slowly, bring the checklist above, test every single fixture, and don't let a sales agent hurry you through — the rush is rarely in your interest.

04

Holding back the final payment — your contract decides

This is where leverage is won or lost, and it turns entirely on your sale and purchase agreement. In a well-drafted SPA the final balance is payable on satisfactory handover — meaning you can refuse to accept the unit and withhold transfer until material defects are remedied. In practice many developers push to transfer title and collect the balance first, then fix snags afterwards under warranty. Whether you can lawfully hold back payment, and how much, depends on your specific clauses, so this is something to settle before you ever reach handover day. Have a Thai lawyer confirm your handover and defect-remedy rights when the contract is signed, and never put your name to an unconditional acceptance while serious defects are unresolved. The contract clauses that matter are covered in our off-plan buying guide.

05

The defect list, repairs and re-inspection

Catching defects is only half the job — confirming they're actually fixed is the other half:

06

The developer warranty — your cover after move-in

Thai condominium law provides statutory warranties on new units: commonly a longer period (often around five years) for major structural elements, and a shorter period (often around one to two years) for other defects and finishes — the precise terms are set out in your contract and the developer's documents, so read them. This warranty is why some buyers accept handover and allow minor snags to be remedied afterwards rather than holding up transfer. The catch: a warranty is only worth as much as the developer's willingness to honour it. A builder with a strong completion and after-sales record will usually respond to claims; an unknown or troubled developer may not. That's why warranty value loops straight back to developer due diligence done before you ever bought — covered in the off-plan guide and the condominium juristic person guide, since the building's management also affects how defects get handled long-term.

Growth Trajectory

Thailand’s condo handover & warranty rules: how we got here

  1. 1925
    Civil and Commercial Code lays the legal root of today's warranty periods
    Sections 600-601 of Thailand's Civil and Commercial Code establish contractor liability for building defects — the structural and shorter-term warranty concepts still cited in condo contracts and this guide's warranty section today.
  2. 1979
    The Condominium Act creates the legal framework for condo ownership
    The Condominium Act B.E. 2522 establishes freehold condo ownership, juristic-person management and the legal basis for developer obligations that later handover and defect practice builds on.
  3. 1991
    Amendments strengthen juristic-person and common-property protections
    Condominium Act Amendment (No. 2, B.E. 2534) reinforces juristic-person governance and common-area protections, relevant to how building-wide defects get raised and resolved after handover.
  4. 2000s-2010s
    Bangkok's high-rise condo boom standardises handover as its own step
    As new-build condo supply surges along the BTS and MRT lines, handover/transfer inspection becomes a distinct, expected appointment in the buying process rather than an informal walkthrough.
  5. 2010s
    Professional snagging-inspection companies emerge as an industry
    Dedicated inspection firms begin operating across Bangkok and the main resort cities, bringing moisture meters, thermal cameras and laser levels to handover day and producing formal photographic defect reports.
  6. 2020-2021
    COVID-19 delays push back developer handover schedules
    Construction slowdowns and site-access restrictions during the pandemic delay completions across Bangkok, forcing many buyers to renegotiate handover dates and, in some cases, final-payment timing with developers.
  7. 2020s-2026
    Public buyer reviews increase pressure on developers
    Buyer Facebook groups, review platforms and social media scrutiny make handover complaints and defect disputes visible in near real time, giving developers a reputational incentive to resolve snag lists faster than the contract strictly requires.

Frequently asked

What is a condo handover inspection in Thailand?Handover (or 'transfer inspection') is the appointment where the developer formally hands you the finished unit and you check it against the contract before you accept it and pay the final balance. For a new-build off-plan condo this is your one real chance to catch construction defects — uneven floors, leaking plumbing, doors that don't close, aircon that doesn't cool, missing fittings — while the developer is still contractually obliged to fix them at their cost. You walk the unit, list every defect in writing (the 'snag list' or defect list), and the developer agrees to remedy them. Accepting the keys and signing off without inspecting properly can weaken your position later, so handover day matters more than most buyers expect.
What should I check on a condo defect (snagging) inspection?Work room by room and test everything that moves, opens, drains or powers on. Floors and walls (level, cracks, hollow tiles, paint finish); doors and windows (alignment, locks, seals, smooth runners); plumbing (water pressure, leaks under sinks, drainage, toilet flush, no sewer smell); electrics (every socket and switch, the consumer unit, light fittings); air conditioning (cooling, drainage, no water dripping); the kitchen and bathroom fittings; the ceiling for water stains; the balcony for drainage and railing safety; and that every item promised in the spec — appliances, wardrobes, fixtures — is actually installed and undamaged. Photograph each defect and note its exact location.
Should I hire a professional snagging inspector in Thailand?For a new-build condo it is usually worth it. Professional inspection companies in Bangkok and the main cities bring moisture meters, thermal cameras, laser levels and electrical testers, and they know the defects developers commonly leave behind — hollow-sounding tiles, hidden leaks, poor waterproofing on balconies and bathrooms, and substandard electrical work. They produce a detailed photographic defect report the developer takes seriously. Fees are modest relative to the price of the unit, and a good inspector routinely finds problems an untrained buyer would miss. If you inspect yourself, go slowly, bring a checklist, and test every single fixture — don't let a sales agent rush you through.
Can I hold back the final payment until defects are fixed?This depends entirely on what your sale and purchase agreement says, which is why the contract matters so much. In a well-drafted SPA the final balance is payable on satisfactory handover, giving you leverage: you can refuse to accept the unit and withhold transfer until material defects are remedied. In practice developers often push to transfer title and take the balance first, then fix snags afterwards under warranty. Whether you can lawfully hold back payment, and how much, turns on your contract clauses — so have a lawyer confirm your handover and defect-remedy rights before the appointment, and never sign an unconditional acceptance while serious defects are unresolved.
What happens after I submit the defect list?The developer takes your written defect list, schedules the repairs, and then you (or your inspector) return for a re-inspection to confirm each item was actually fixed — not just ticked off. Minor cosmetic snags may be agreed for completion shortly after move-in; structural or safety defects should be resolved before you accept the unit. Keep the signed defect list and all photos, because they're your evidence if a 'fixed' item fails again. Only sign final acceptance once you're satisfied, or once the contract's defect-remedy mechanism is properly documented.
How long is the developer's warranty on a new condo in Thailand?Thai condominium law provides statutory warranties on new units: commonly a longer period (often around five years) covering major structural elements, and a shorter period (often around one to two years) covering other defects and finishes — the exact terms are set out in your contract and the developer's documents. The warranty is why some buyers accept handover and let minor snags be fixed afterwards. But warranties are only as good as the developer's willingness to honour them, which loops back to developer due diligence: a builder with a strong completion and after-sales record is far more likely to actually respond to a warranty claim than one you've never heard of.
